Objectives: To compare carotid endarterectomy patch angioplasty (p-CEA) with eversion carotid endarterectomy (e-CEA) and associated risks of early cardio-cerebrovascular complications. Methods: The study was a prospective randomized single-blind trial, monocentric, clinically applicable, descriptive analytical and comparative. From June 2021 to June 2023, 62 consecutive patients with symptomatic and asymptomatic stenosis of the internal carotid artery, admitted to our department and randomized into two groups: carotid endarterectomy with patch angioplasty and eversion carotid endarterectomy. Follow-up for 30 days after surgery. Results: During surgery e-CEA, 70% patients had an arrhythmia, and 24 hours after 66.7%, seven days after 46.7% and month after 13.3%. During surgery p-CEA, 33.3% patients had an arrhythmia, 24 hours later 33.3%, 7 days after 13.3% and 30 days after 13.3% patients. Statistically significant difference observed during surgery (Fishers p=0.004). One day after the surgery rate of patients with arrhythmia that were treated e-CEA has decreased, but it was still higher than after p-CEA (Fishers p=0.010). Conclusion: The frequency and categorization of postoperative cardiac arrhythmias after eversion carotid endarterectomy, the clinical implications of various postoperative heart rhythm disturbances and their long-term effects on patients need to be further investigate through sufficiently powered randomized controlled studies

According to the WHO data from May 2022, the COVID-19 pandemic caused a global health crisis with more than 515 million infected and over 6 million deaths as a result of COVID-19. Just over 11.5 billion vaccines have been administered to prevent severe disease and mortality from SARS-CoV-2 infection. In addition to that, COVID-19 had dramatic effects on all aspects of the society, including the fundamental factors of its functionality - education and health, preventing the continuity of its "normal" functioning. Crisis management measures have had more or less successful results in different countries, but no health system has been able to fully address the effects of the pandemic on the health of the population. The course of the epidemiological crisis and the success of the implementation of global vaccination measures are directly related to the adaptability of individual societies / its capacity to change and adapt. in analyzing the situation and predicting the course of the pandemic. Analytical ability, reliability of prediction, but also flexibility of legislative and executive power, are the most prominent parameters of a society that is ready for the unpredictability of the course and outcome of the global social crisis caused by the pandemic. In the local concept of the development of higher education until 2030, it is necessary to include the mentioned, global principles of adaptability to crises in all spheres of social activity. One of the most powerful instruments of social understanding is education, and here lies the potential of society to adapt and change in order to adapt to the challenges of the modern world through the acceptance of values and norms based on knowledge.

SUMMARY The aim of the study was to investigate if preoperative blood flow velocity in femoral vein in different positions of the hip during total hip arthroplasty (THA) is a predictor of postoperative deep vein thrombosis (DVT). In patients undergoing THA, blood flow velocity and diameter of proximal femoral vein on THA side were measured preoperatively in four flexion positions of the hip. After THA, patients were followed up for 42 days for DVT occurrence, and clinical features of patients with and without postoperative DVT were compared. The mean blood flow velocity in maximal flexion (90º+) preoperatively was significantly lower in patients with postoperative DVT (19/103) compared to patients without it (8.4±2 cm/s vs. 10.6±2.3 cm/s; p<0.001). Using the receiver operating characteristic curve analysis, the cut-off value for blood flow velocity during maximal flexion was 8.24 cm/s. In addition, anesthesia duration, duration of surgical position of the patient, body mass index, amount of blood transfused after surgery, and clinical signs of DVT were markedly different between patients with and those without postoperative DVT. Blood flow velocity in femoral vein in maximal flexion of the hip (90º+) measured prior to THA is an independent predictor of postoperative DVT.

Aim To determine preferable type of treatment in our clinical circumstances by following two groups of patients with critical limb ischemia (CLI), who were treated endovascularly and surgically. Methods Research was carried out in the form of a prospective study of 80 patients with CLI and Trans-Atlantic Inter-Society Consensus (TASC) C or D type of arterial disease, with American Society of Anesthesiology (ASA) class III risk, who were randomly divided in two groups as per the treatment they received, surgical and endovascular. Patients were followed during 28 months using clinical examination and Duplex Ultrasound (DUS) in accordance with prescheduled control visits. Results There was a statistical difference between surgical and endovascular group in two years patency (82.5% vs. 55%; p=0.022) but it did not result in the difference in amputation free survival (AFS) (95% vs. 85%; p=0.171) or two-year freedom from major adverse limb events (MALE) (87.5 vs. 77.5; p=0.254). Also, there was no difference in the overall survival of patients (100% vs. 97.5%; p=0.317). Conclusion Initial endovascular treatment is a preferred form of the treatment for selected patient population.

Aim To compare hospital costs of acute limb ischemia treatment in two periods of time and to show evidence of long-term repercussions on reducing costs during successful treatment. Methods Retrospective analysis of data obtained from 100 patients' medical history in the period 2000-2016 at the Clinic of Vascular Surgery Sarajevo: group A - 60 patients with acute limb ischemia in the period 2005-2016 and group B - 40 patients with acute limb ischemia (ALI) in the period 2000-2005. From 2000 to 2005 conservative treatment method was used, invasive diagnostic and surgical procedures were often delayed for a shorter or longer period of time. During the period from 2005 to 2016, the management model and safe practice included emergency diagnostic procedures, colour-Doppler, arteriography, emergency surgery (embolectomy by Fogharty and if necessary, vascular by-pass). Results Better health service for the patients with acute limb ischemia was offered in the period 2005-2016, which relied on proven medical treatment trends. The largest share of the total costs of each patient included costs of hospital bed with significant difference between the period 2005-2016 and 2000-2005, mean of 1398.71 KM and 2480.45KM, respectively (p<0.0001), indicating rationalization of time that patients spend at the Vascular Clinic. Conclusion This trend of money/fund savings is an example of good practice, effectiveness and efficiency in the treatment of ALI and as such was used in patients with other vascular diseases.

AIM: To compare hospital costs of acute deep vein thrombosis (ADVT) treatment in two periods of time. Evidence of repercussions on reducing costs during successful treatment. Attention was given to the necessity, costs and effectiveness of diagnostic procedures, treatment and complications. METHODS: A retrospective analysis of data obtained from patients medical history in a period from 2000 to 2016. Model management and safe practice of ADVT care consisted of clinical examination, laboratory, colour Doppler and invasive diagnostics. In a treatment was used continuous infusion un-fractionated heparin for 40 patients from 2000th till 2006th and low molecular weight heparin for 40 patients from 2006th till 2016th. All patients were converted to oral anticoagulants. RESULTS: When we look at the overall picture of improving the management model, safe practices and economic rationalization, we conclude that we offer better health service for the patients with ADVT at the moment, which relies on proven medical treatment trends. While we do not forget responsibility towards a society of which depends on treatment funding. CONCLUSION: The implementation of a conceptually new model of management of ADVT did not contribute rise of the desired outcomes, but it justified the positive economic viability of introduced changes at the Clinic of Vascular surgery than the previous concept.

Introduction: Stroke is one of the largest socio medical problems of modern times. In addition to the third leading cause of death, it is the first cause of non-trauma disability. Numerous studies show a correlation of risk factors and arteriosclerotic lesions in the coronary arteries and carotid arteries. Patients and methods: Study was conducted at the Clinical Center University of Sarajevo, Clinic for Cardiology surgery, methodologically cross-sectional study and partly manipulative and clinical prevention study, conducted on a representative sample of 100 patients. The subject was divided into 2 groups, coronary and non-coronary patients. Both groups of patients underwent color Doppler of carotid arteries, medical history and laboratory analysis. Results: The results confirm the hypothesis that the critical carotid artery stenosis is more present in patients with coronary disease, while the association of risk factors has been demonstrated for diabetes, hypertension and dyslipidemia. Conclusion: Screening of carotid arteries in patients scheduled for coronary revascularization is essential. With the presence of critical stenosis of the carotid artery, surgery of carotid artery should be done before coronary revascularization. The implementation of aggressive education and prevention of risk factors for cardiovascular disease is needed.

Introduction: Atherosclerosis blood vessels, be it on extra-cranial or intra-cranial circulation, the most common cause of incidents such as cerebro-vascular insult (ICV). Carotid endarterectomy (CEA) is a preventive operation to reduce the risk of stroke and it can be performed by eversion carotid endarterectomy (E-CEA) or a classical carotid endarterectomy (C-CEA). The aim of this study was to investigate the influence of the used techniques in basic perioperative results and the incidence of postoperative complications. Materials and Methods: It was retrospective-prospective study that involved 173 patients, with carotid stenosis, who underwent CEA, in the period of time December 2013 till December 2016. Subjects were divided into two groups in respect of technique: 90 patients were treated with E-CEA and 83 patients were treated with C-CEA. Results: Between two groups revealed a significant difference in favor of the patients from group E-CEA in the length of the surgery (92.56 ± 29.11 min. vs. 104.04 ± 18.01 min., P = 0.000), the time of clamping the carotid arteries (11.83 ± 1.81 min. vs. 23.69 ± 5:39 min., p = 0.000), the amount of post-operative drainage (25.33 ± 24.67 ml. vs. 36.14 ± 14:32 ml., p = 0.001), time spent in the intensive care unit (± 25.43 vs. 13:51 hours 34.54 ± 35.81 hours, p = 0.000), and the length of stay (4.60 ± 0.90 days vs. 5:42 ± 1.80 days, p = 0.001). In the patients of the group E-CEA, fewer number of individual postoperative complications without statistical significance: ICV (2.2% vs. 4.8%, p = 0.351), cardiac arrhythmia (2.2% vs. 4.8%, p = 0.351), transitory ischaemic attack (TIA) and cognitive disorder (2.2% vs. 7.2%, p = 0.117), mortality (1.1% vs. 1.2%, p = 0.954); and the total number of postoperative complications was significantly less in the same patients (7.77% vs. 18.7%, p = 0.042). Conclusion: The results of this study clearly indicate that operating techniques affects the specified monitored outcomes of vascular treatment of carotid arteries in favor of E-CEA technique. It would be ideally that the conclusions of this study contribute to broader use of E-CEA in treatment of carotid stenosis.

Objective: The aim of this study is to evaluate post-operative complications after myocardial revascularisation in patients with very severe ischaemic heart disease. Men typically have a higher incidence of coronary disease than women. Ischaemic heart disease is characterised by reduced blood supply to the heart. The coronary arteries supply blood to the heart muscle, and since no alternative blood supply exists, a blockage in the coronary arteries reduces the supply of blood to the heart muscle. Myocardial infarction can cause very severe dysfunction of the left ventricle. In spite of new medical and surgical treatments, the number of patients with ischaemic disease is constantly increasing. Patients and Methods: A group of 80 patients with ischaemic heart and myocardial infarc- tion was observed, and 40 of them surgically treated in the period 2010-2013. In this study we evaluated only those surgically treated patients. The results: Post-operative complications in patients surgically treated included: ICV 2.5% (1/40); bleeding 2.5% (1/40); arrhythmia 17.5% (7/40); pleural effusion 7.5% (3/40); media- stinitis 2.5% (1/40); sepsis 2.5% (1/40); acute renal insufficiency 2.5% (1/40); multiple organ failure 7.5% (3/40); and perioperative death 2.5% (1/40). Conclusion: Surgical treatment of patients with severe ischaemic disease as a result of myocardial infarction can be performed with minimal operative and post-operative compli- cations, especially in elective cases.

Objective: In our study we wanted to showed the safety, feasibility, efficacy and way how to solve the problems of endovascular repair for aortic dissection with insufficient proximal Landing Zone. Methods: The clinical data of all the patients with insufficient proximal Landing Zone (PLZ) for endovascular repair for aortic aneurism and dissection Stanford type B for the period from October 2013 to June 2014 was prospectively reviewed. According to the classification proposed by Mitchell et al, aortic Zone 0 was involved in 3 cases, Zone 1 in 1 case, Zone 2 in 9 cases and Zone 3 in 6 cases (19 patients in total). A hybrid surgical procedure of supraortic debranching and revascularization, with direct anastomosed truncus brachiocephalicus and left common carotid artery, were performed to obtain an adequate aortic PLZ. Revascularization of the left subclavian artery was carried out on the patient with dissection Stanford type B and short PLZ 2. Results: There was no significant difference of risk factors between Zone 0, Zone 1, and Zone 2 (Table 1.), but the length of the PLZ significantly differed between groups (p<0.01) and there is no significant difference in technical and clinical success rate among the groups. Conclusion: The procedure of extending insufficient PLZ for endovascular repair for aortic arch pathology is feasible and relatively safe. The TEVAR applicability in such aortic disorders could be extended.

Introduction: The aim of this study was to present the incidence of the vascular complications that had to be surgically treated during the two-year period of transfemoral cardiac catheterization procedure and to identify the risk factors associated with the complications.Methods: A retrospective two-year study of post-catheterization complications with the six-month postoperative follow-up and analysis of risk factors was done. Patients with cardiovascular diseases who underwent therapeutic or diagnostic coronary angiography in the period of 2012-2013 were included in the study. A total of 1320 patients were subjected to catheterization for coronary angiography, of which 24 had vascular complications that had to be surgically treated. Indications for operative treatment included rapid growth of pseudoaneurysm, hemorrhage, large hematoma, hemodynamic instability, failure of the targeted compression therapy.Results: Twenty-four patients experienced some kind of post-operative complication. Infection and dehiscence of surgical wound were the two most common complications. There were no fatalities. The average length of a hospitalization was 4 days. The important risk factors are gender (women more than man), obesity, concomitant use of anticoagulation therapy and antiplatelet therapy after catheterization.Conclusion: Insufficient length of the compression of the punctured place and increased risks of a pseudoaneurysm formation, such as female gender, obesity, and use of a combined anticoagulant therapy are the main causes of these complications. Late vascular complications are not uncommon.

Pseudo aneurysms as complications are a major source of morbidity after cardiac catheterization. Their incidence varies in the literature due to different definitions, methods of interrogation and presence of certain complications. We found in the literature that post-catheterization lesions occur in approximately 0.05% of treated patients after diagnostic catheterization and up to 1.2% after more complex procedures. The aim of this retrospective study was to determine the incidence of pseudo aneurysm after cardiac catheterization using the physical findings and color Doppler ultrasound. In the study, which encompasses the period of 2009-2010, there were 400 coronary angiography with trans femoral catheterization. After compression hemostasis was carried out, each patient was checked after 24 hours and again after 48 hours. Diagnostic coronary angiography was made in 400 patients (100%), out of which, 110 patients (27,5%) had a percutaneous coronary intervention with stent placement (PCI), Color Doppler ultrasound of femoral artery was normal in 384 (96.3%), local hematoma was found in 360 (90%), pseudo aneurysm in 14 (3.7%), AV fistula in 1 (0.25%) and dissection of the femoral artery in 1 (0.25%) patient. Complications in 16 patients were treated surgically, in 7 patients they were treated conservatively and in 1 case thrombin was applied within pseudo aneurism. Patients with complications were more often present with concomitant use of anticoagulant and anti platelet tablets than patients without complications (P = 0.003). Prevention of post catheterization pseudo aneurysm can be achieved by proper puncture technique, choosing the right place and right post interventional hemostatic compression with or without external devices. Special attention should be paid to the use of anti platelet drugs and anticoagulant and combinations thereof.

PURPOSE Cerebrovascular events (CVE) are the third most common cause of death in Western countries and about 65-70% of CVE are due to atherosclerotic disease of carotid arteries. Color Doppler scanning is used to evaluate the presence, severity and type of atheromatous plaques as well as velocity parameters of carotid arteries. We performed this study to correlate data of morphological and velocity parameters with clinical variables in patients following CVE. METHODS We included total of 211 pts who had CVE, 118 females, 93 males, mean age 71.1 +/- SD 12.5 years. Out of total number of pts (n = 211) 93 pts had transient ischemic attacks (TIAs), 49 had recurrent TIAs (rTIAs), 44 had ischemic stroke (IS), and 25 had recurrent IS (rIS). As a control group we took 50 pts without CVE but with at least three multiple risk factor (MRF). Morphological parameters were; plaque composition and echogenecity. Velocity parameters were: peak-systolic velocity (PSV) and end-diastolic velocity (EDV). The following MRF were evaluated: age, gender, hypertension, tobacco smoking, hyperlipidemia (total cholesterol and LDL-cholesterol), obesity, and diabetes mellitus. Examination was performed on CCA/ICA segment. RESULTS We found significant presence of heterogeneous plaques in TIAs and rIS subgroup, p < 0.014, and borderline significance for the rTIAs and IS subgroups, p < 0.04. We found significant difference in PSV in TIAs and rTIAs subgroups vs. controls (PSV 103 cm/s vs. PSV in controls 87 cm/s, p < 0.01). Decreased EDV, below 20 cm/s, was found in all subgroups, p < 0.01, while EDV, below 16 cm/s, was found in IS and rIS subgroups. MRF score of CVE group was 4.34 vs. 3.65 in controls, p < 0.012, while MRF score in TIAs and rTIAs vs. IS and rIS subgroups was 4.34 vs. 4.51, NS, p = 0.14. We found a significant correlation (95% CI) of tobacco smoking, obesity and arterial hypertension with presence of heterogeneous plaques, p = 0.0069. Interestingly, hyperlipidemia showed no correlation with heterogeneous plaques, p = 0.027. CONCLUSIONS (i) in CVE group we found significant presence of heterogeneous plaques in TIAs and rIS subgroups, (ii) in the pts with TIAs and rTIAs events we found significant increase in PSV, (iii) EDV below 16 cm/sec was a significant single predictor of IS and rIS events, (iv) MRF score was significantly increase in the pts with CVE compared to controls, but between CVE subgroups there was no significant difference.

INTRODUCTION Break ankle today is becoming more frequent. There is a dilemma to operate immediately upon receipt or delayed surgical treatment for a day or two. THE AIM OF THE WORK This work aims at showing the importance of the anatomy, mechanism of injury, injury classification, diagnostic and therapeutic methods in treatment of brake ankle from our experience. MATERIAL AND METHODS In the past year in our clinic there were 30 patients treated for all types of ankle fractures, and these patients were divided in two groups. Patients of the first group are those immediately operated, and the second group were with delayed surgery. The results showed that the patients of the first group had better healing, fewer complications, better and faster rehabilitation. Second groups of patients were with complications in terms dehiscence of wounds, bad healing fracture and DVT. CONCLUSION Our results showed that better result in the treatment of ankle fractures is achieved by aggressive treatment immediately after trauma, with reconstruction of articular surface and tibiofibular syndesmosis with early rehabilitation.
