Background: Carotid endarterectomy (CEA) is an effective and safe treatment of stenosed carotid arteries, and is a preventive operation with well-defined indications. It is associated with a loss of the baroreceptor reflex and postoperatively increased hemodynamic parameters. Objective: The aim of the study was to confirm the sensitivity of baroreceptors and the impact on arterial pressure and heart rate in unilateral and bilateral eversion carotid endarterectomies. Methods: A retrospective study was conducted with 30 patients treated with E-CEA in local anesthesia at the Clinic for cardiovascular surgery from December 2019 to May 2021, due to stenosis of the carotid arteries. Patients were divided into two groups: 15 patients in group A (patients with unilateral E-CEA; 15 patients in group B: patients with bilateral E-CEA). Results: Out of the total of 30 patients included in the research, 15 patients in groups A and B respectively, there were no statistically significant differences in regards to gender (p= 0,245) and preoperative risk factors: smoking (p=0,449); hypertension (p=0,388); diabetes (p= 0,714); hyperlipidemia (p=0.388), coronary disease (p=0.461) and symptomatic stenosis of the carotid arteries (p=0.449). Noted were the statistically significant differences in values of systolic and diastolic pressure on the 3rd postoperative days in patients with bilateral E-CEA (p=0,001; p=0,001), a statistically significant difference in the heart rate was not found in the analyzed groups in the postoperative period (p=0,225; p=0,994). Conclusion: This study identified statistically significant differences in values of systolic and diastolic pressure in the early postoperative period. In his period, early detection and correction of these hemodynamic disorders are needed.

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.

Background: Necrotizing enterocolitis (NEC) is the most common life-threatening gastrointestinal emergency associated with prematurity. Timely diagnosis and adequate treatment are crucial to reduce the morbidity and mortality of the affected infants. The aim of this study was to evaluate the diagnostic yield of bowel dilatation on plane abdominal radiography (AR) in the early diagnosis and NEC severity in preterm infants. Methods: We retrospectively reviewed initial ARs of 50 preterm infants with NEC ≥ stage II admitted to the neonatal intensive care unit (NICU) in a tertiary-care hospital. The largest bowel loops diameters (AD), the latero-lateral diameters of the peduncle of the first lumbar vertebra (L1), and the distance of the upper edge of the first lumbar vertebra and the lower edge of the second one, including the disc space (L1–L2), were measured. All anteroposterior ARs were done in a supine projection on the day of onset of the initial symptoms of NEC. Results: Preterm infants with surgical NEC showed a statistically significant increase in the AD/L1 ratio (p < 0.001) and AD/L1-L2 ratio (p < 0.001) compared with preterm infants with medical NEC. We found no significant association between the site of the most distended bowel loop and the severity of NEC (p > 0.05). Conclusion: Bowel loop distension on initial AR may serve as an additional diagnostic tool in the early diagnosis and severity of stages II/III NEC. Further prospective clinical studies should validate the results from this study.

Introduction: Abdominal aortic aneurysm represents a local pathological dilatation of the abdominal aorta. It is caused by structural weakness of aortic wall but there are many other risk factors that may positively correlate with incidence of AAA like hypertension, smoking, male gender, older age, family history etc. Aim: The purpose of the study was to evaluate the correlation of atherosclerotic risk factors and the size of aortic aneurysm in patients that were admitted for the surgical treatment at the Clinic for cardiovascular surgery in Sarajevo during period 2016-2019. Methods: The study was designed as a retrospective study with one group of patients that was conducted at the Clinical Center of the University of Sarajevo at the Clinic for Cardiovascular Surgery. It included 150 patients, 126 males and 24 females, all of them with infrarenal localization of AAA. From medical records we have collected relevant anamnestic data (age, gender, positive family history, diabetes mellitus, hypertension, hyperlipidemia, smoking, alcohol consumption and obesity). The size of aneurysm was determined by both ultrasound and CT arteriography. The data are processed in the Statistical Package for Social Sciences Ver. 22.0. The results are tabulated or graphically showed, and level of statistical significance was set at p <0.05. Results: Total amount of 129 of patients (86%) had hypertension, 57.3% (n=86) of them were smokers, 18.7% (n = 28) were former smokers, and 24% (n = 36) were non-smokers Blood lipid level analysis have shown that 44% (n = 66) of patients were normolipemic, while elevated blood lipid levels were found in 56% (n = 84) of patients. Diabetes mellitus was present in 17.3% (n = 26) of patients, 2.7% (n = 4) of them had an insulin-dependent form, while 14.7% (n = 22) of the analyzed patients had insulin independent DM. Almost half of total number of patients (46%, n = 69) were obese. 19.3% (n = 29) of patients consumed alcohol while the 80.7% (n = 121) denied alcohol consumption. Ratio of males in comparison to females was 5:1. The average age in males was 69.79 ± 8.16 years and 72.13 ± 9.11 years in females. Significant statistical correlation of AAA size and risk of atherosclerosis factor has not been established. We have found that there is a significant positive correlation between size of aneurysm and risk of rupture (p= 0,000<0,05). Conclusion: Although risk factors of atherosclerosis were present, statistically positive correlation was not confirmed between the size of AAA and analyzed risk factors.

Introduction: Color Doppler and CT angiography are diagnostic methods commonly used to determine the degree of carotid stenosis. Aim: To evaluate how the degree of carotid stenosis determined by the Color Doppler correlates with the degree of stenosis determined by the CT angiography. Material and Methods: The study was designed as a retrospective study. It included 42 patients with carotid stenosis. From medical records we collected anamnestic data (gender, age and risk factors - hypertension, hyperlipidemia, diabetes, smoking and obesity) and the results regarding the degree of carotid stenosis determined by Color Doppler and CT angiography. Results: Out of the total number of patients (n=42), 73.8% were males and 26.2% were females. Average age of examined patients was 65.24±8.61. Most frequent risk factor of atherosclerosis was hypertension, followed by hyperlipidemia and smoking. NASCET grading distinguishes: first (0-29%), second (30-69%) and third (70-99%) degree of carotid stenosis. According to the Color Doppler evaluation findings, the second degree had 8 patients and 34 patients had the third degree of carotid stenosis. CT angiography have shown that 35 patients had third degree carotid stenosis, while 7 patients had the second degree carotid stenosis. In only one case results of evaluated methods differed regarding assessment of carotid stenosis. We have found that there is a significant positive correlation of the degree of carotid stenosis determined by the Color Doppler with the degree of stenosis determined by CT angiography (p=0.0002). Risk factors of atherosclerosis did not have a significant correlation with the degree of carotid stenosis (p>0.05). Conclusion: The degree of carotid stenosis estimated by the Color Doppler positively correlates with the degree of stenosis estimated by CT angiography.

Introduction: We can define extracranial carotid artery aneurysm (ECAA) as bulb dilatation greater than 200% of the diameter of the internal carotid artery (ICA) or in a case of common carotid artery (CCA) greater than 150% of the diameter. Surgical intervention is required for the treatment of this disease.Case report: This study presents an open vascular surgical procedure to resolve ECAA. We report a case of 61 years old woman with an extracranial internal carotid artery berry aneurysm, presented with a headache and dizziness when turning the head aside. Classic open surgery was performed and the lumen of berry aneurysm was separated with three clips from the lumen of ICA.Conclusions: The open surgical approach is the method of choice for the treatment of extracranial internal carotid artery pathological conditions.

Introduction: Carotid endarterectomy (CEA) is a standard treatment for the prevention of stroke and death in patients with significant stenosis of the internal carotid artery. Eversion endarterectomy is warranted in patients with symptoms of cerebral ischemia and the degree of stenosis of 70-99%. The same is suitable for treating a symptomatic carotid artery stenosis with contralateral stenosis (50-70%). Purpose: The aim of this study was to evaluate perioperative complications (ICV, TIA, MI, mortality) in patients treated with carotid eversion endarterectomy with unilateral and bilateral symptomatic stenosis (with bilateral stenosis treated with ACI stenosis ≥70%). Patients and Methods: The study included 139 patients with symptomatic carotid artery stenosis at the Department of Vascular Surgery of the University Clinical Center of Sarajevo in the period from January 2012 to December 2014 year. Given the involvement of ACI stenosis patients were divided into two groups. Group A consisted of 74 patients with bilateral stenosis (surgically treated with ACI stenosis ≥70%, while the degree of stenosis opposite ACI was from 50-70%), and group B of 65 patients with unilateral stenosis ≥70%. Results: Of the 139 patients included in the study, in the group A was 74, of which 46 male (62.2%) and 28 female (37.8%), while in group B were 42 male (64.6%) and 23 female (35.4%) (p = 0.90). The subjects in group A were slightly older 65.9 (± 7.8) compared to group B 64.2 (± 7.7) (p = 0.17). Analysis of risk factors indicating a higher number in Group A compared to group B, but the difference was not statistically significant: 34 smokers (45.9%) versus 36 (55.4%); p = 0:34), patients with hypertension (63 (85.1%) against the 52 (80.0%); p = 0.56), with statin therapy (62 (83.8%) versus 52 (80.0%); p = 0.72), diabetes (18 (24.3%) versus 18 (27.7%); p = 0.79) and with a heart disease (18 (24.3%) versus 7 (10.8%); p = 0.06). Analysis of the frequency of perioperative complications between the groups was not statistically significant: ICV (2/74 versus 3/65; p = 1.00), TIA (2/74 versus 3/65; p = 0.88), one death was recorded in group A, while myocardial infarction (MI) we had in either group. Conclusion: In this study, no statistically about significant differences in the number of perioperative complications (from 0 to 30 days) between the two groups. With this risk is acceptable to perform carotid endarterectomy in a patient in the opposite ACI stenosis of 50-70%.

ABSTRACT Introduction: In Bosnia and Herzegovina according to available data, treatment of incompetent superficial lower extremity varicose veins by endovenous laser ablation (EVLA) has been introduced two years ago and so far no paper has been published regarding results of EVLA treatment of patients from our country. We wanted to present our results with EVLA treatment. Aim of study: to evaluate and compare primary posttreatment outcomes of endovenous laser ablation (EVLA) with classical surgical method of varicose vein treatment. Patients and methods: The study was clinical and prospective. It was carried out at Clinic for vascular surgery in Sarajevo where fifty-eight (58) patients received surgical treatment for varicose veins and in Aesthetic Surgery Center “Nasa mala klinika” in Sarajevo were sixty-one (61) patients with varicose veins were treated by endovenous laser ablation. Total 119 patients (limbs) with pathologic reflux only in great saphenous vein were evaluated between 1st of January 2013 and 31st of April 2014. Following primary outcome endpoints were evaluated smean day of return to normal everyday activities, patient subjective quantification of pain during first seven days after intervention, incidence of deep venous thrombosis (DVT), incidence of wound bleeding requiring surgical intervention, incidence of peri-saphenous vein hematoma and infection rate. Results: Mean of return to normal activities (expressed in days after intervention); EVLA vs. stripping (surgery) =1.21vs12.24, T test 13,619; p=0, 000, p<0,05. T test was used for comparing Mean value of visual pain analog scale for the first 7 days between groups, for all seven days pain was significantly higher in surgical group of patients as compared to EVLA group; p<0,05. Incidence of hematoma greater than 1% of total body surface area was significantly higher in patients receiving surgical treatment; Pearson Chi Square=23,830, p<0,05; odds ratio:10,453. Incidences of infection, deep venous thrombosis and posttreatment bleeding were not statistically different between analyzed groups; EVLA vs Surgery (Pearson Chi Square =3,237; p>0,05; Pearson Chi Square=2,139, p>0,05, Pearson Chi Square=2,139, p>0,05, respectively.) Conclusion: EVLA offers better patient recovery in terms of significantly lower post treatment pain, faster return to everyday activities and lower incidence of bruising (hematomas).

ABSTRACT Introduction: Risk factors for development of extremity artery atherosclerosis are the same as for coronary and cerebrovascular atherosclerosis namely, diabetes mellitus, hyperlipidemia, arterial hypertension, age and smoking. Atherosclerosis is polyarterial disease that clinically manifests itself most frequently in the form coronary, cerebrovascular or peripheral arterial disease (PAD). All of them have common, ominous and final pathologic step – atherosclerotic plaque rupture that might eventually lead to atherothrombosis and signs of ischemia. There are few studies of risk factor for peripheral artery disease (PAD). Aim of study: To identify prevalence of known risk factors for atherosclerosis in patients treated for acute atherothrombosis of extremity arteries. Patients and methods: Eighty patient were analyzed with regard to the prevalence of five risk factors for atherosclerosis (diabetes mellitus, smoking, hypertension, hyperlipidemia and age). 80 patients were divided into two groups (Group A and B) depending on country i.e. hospital where they received treatment for acute atherothrombosis of extremity artery. Group A consisted of patients treated at Clinic for vascular surgery in Sarajevo, while patients in Group B were treated in Trollhattan in Sweden at NAL hospital. This study was clinical, comparative, retrospective-prospective. Results: In group A, 20% of patients had diabetes mellitus while in group B prevalence of diabetics was lower (12,5%) but difference was not statistically significant p>0.05. Sixty percent of patients (60%) in group A were smokers. In Sweden, habit of smoking is not as common as in Balkan countries and consequently only 22,5% of patients were smokers in Group l, difference was statistically significant, p<0.05. In patients assigned to group A, 42.5% of them had diagnosis of hypertension while in Group B, 35% of patients were hypertensive. Difference was not statistically significant, p>0.05. 37.5% of patients in group A and 20% of patients in group B had hyperlipidemia. Difference was not statistically significant, p>0.05. In Group A mean age of patients was 67.85 years while mean age in Group B was 73.63. Age difference was statistically significant, p<0.05. Conclusion: Prevalence of risk factors of atherosclerosis in peripheral artery disease were evaluated in this study. Significant difference in prevalence of two risk factors were determined namely, smoking and mean age of occurrence of atherothrombosis. Quiting smoking and adopting healthier life habits may lead to reduction of prevalence PAD in younger patients in Bosnia and Herzegovina.
