We present a case of 52 year old male with an acute renal failure that took place 4 days after open transabdominal surgery repair of infrarenal abdominal aneurysm along with aneurysm of left common iliac artery and dilatation of left external iliac artery. Patient was subjected to 13 hemodialysis treatments that resulted in satisfactory recovery of renal function. One month after aneurysm repair he developed the right ureteral leak, consequently urinoma and acute renal failure once again. We suppose that ureteral leak was related to segmental ischemic necrosis of right ureter but not to traction or other iatrogenic ureteral injury. Percutaneous nephrostomy and insertion of ureteral stent was resulted in complete recovery of renal function.

INTRODUCTION Preoperative evaluation of patients with aneurysm of abdominal aorta includes CT angiography. Stenotic changes of iliac arteries greater than 50% imply consideration of aorto-femoral reconstruction in order to avoid upcoming occlusion of iliac arteries in the near future. AIM Comparison of detection of arterial stenotic changes between CT and Seldinger angiographies that are > or = 50% in aorto-iliaco femoral region. METHODS AND PATIENTS This is a retrospective descriptive study that included 73 patients diagnosed with AAA from 2006-2008. Both CT and Seldinger angiography were performed on 43 patients, while 30 patients were evaluated only with CT angiography. RESULTS out of 43 patients that were evaluated with both CT and Seldinger angiography, 30 of them were males and 13 were females. Stenotic changes > or = 50% detected by CT are as follows: aortic bifurcation -9.3% of patients, common iliac artery-11.62% of patients, internal iliac artery -46.51% of patients, external iliac artery 25.58% of patients and 4.6% of patients in case od common femoral artery. Seldinger angiography detected stenotic changes > or = 50% as follows: aortic bifurcation -16.27% of patients, common iliac artery -16.27% of patients, internal iliac artery -60.46% of patients, external iliac artery 32.55% of patients and 9.3% of stenotic changes at the level of common femoral artery. CONCLUSION Seldinger angiography detected more stenotic changes of iliac artery segment in comparison to CT angiography and in that aspect every suspicion of potential stenotic change in iliac artery segment should be additionally evaluated by Seldinger angiogram in case of patients with AAA.

Objective: Comparison of detection and determination of critical carotid stenosis between two radiological methods: color doppler ultrasound and Seldinger angiography. Methods: This is retrospective study that has included 64 patients that were hospitalized at the Clinic for Vascular surgery, Clinical Centre of University of Sarajevo, from 2006-2008.. 43 patients had carortid artery stenosis from 50-99%, all patients confirmed of having carotid stenosis greater than 60% were subjected to Seldinger angiography. Results confirming critical stenosis of both methods were compared. Degree of carotid stenosis with color doppler was determined on basis of peak systolic velocity and in the case of angiography stenosis was determined by measuring stenotic segment with milimeter tape and comparing it to diameter of normal segment. Results: according to color doppler investigation 32/43 patients had critical carotid stenosis ≥70% . In case of Seldinger angiogram ratio of positive cases was 37/43. In 86% of cases critical stenosis was confirmed by both methods. 5 angiograms showed greater degree of carotid stenosis than color doppler investigation. Out of 2 complete occlussions of internal carotid artery detected by color doppler only one was confirmed by Seldinger angiography, the other was described as stenosis of very high degree.. Discussion: Compatibility of successfull recognition of critical carotid stenosis for both methods is 86%, that figure does not deviate significantly from results pointed out by other studies where compatibility was reported to be 91%. Conclusion: Both methods should be combined in order to make sound indication for operative treatment since beside having segmental stenosis of carotid artery, imperative for carrying out succsseful operation is regular appearance of distal portion of internal carotid artery that is best visualised by one of available angiographies.

At the end of IX and beginning of the X century begins development and renaissance of the medicine called Arabic, and which main representatives were: Ali at-Taberi, Ahmed at-Taberi, Ar-Razi (Rhazes), Ali ibn al-Abbas al-Magusi (Haly), ibn al-Baitar, ibn al-Qasim al-Zahrawi (Abulcasis), ibn Sina (Avicenna), ibn al-Haitam (Alhazen), ibn Abi al-Ala Zuhr (Avenzor), ibn Rushd (Averroes) and ibn al-Nafis. Doctors Taberi, Magusi and Razi were born as Persians. Each of the listed great doctors of the Arab medicine in their own way made legacy to the medical science and profession, and left lasting impression in the history of medicine. Majority of them is well known in the West well and have their place in the text-books as donors of significant medical treasure, without which medicine would probably, especially the one at the Middle dark century, be pale and prosaic, insufficiently studied and misunderstood, etc. Abdullah ibn Sina (Avicenna) remained unsurpassed in the series of above listed. Close to him can only come Alauddin ibn al-Nafis, who will in mid-XII century rebut some of the theories made by Avicenna and all his predecessors, from which he collected material for his big al-Kanun fit-tibb (Cannon of medicine). Cannon will be commended for centuries and fulfilled with new knowledge. One of the numerous and perhaps the best comments-Excerpts is from Nafis-Mugaz al-Quanun, article published as a reprint in War Sarajevo under the siege during 1995 in Bosnian language, translated from Arabic by the professor Sacir Sikiric and chief physician Hamdija Karamehmedovic in 1961. Today, at least 740 years since professor from Cairo and director of the Hospital A-Mansuri in Cairo Alauddin ibn Nefis (1210-1288), in his paper about pulse described small (pulmonary) blood circulatory system and coronary circulation. At the most popular search engines very often we can find its name, especially in English language. Majority of quotes about al-Nafis are on Arabic or Turkish language, although Ibn Nafis discovery is of world wide importance. Author of this article is among rare ones who in some of the indexed magazines emphasized of that event, and on that debated also some authors from Great Britain and USA in the respectable magazine Annals of Internal medicine. Citations in majority mentioning other two "describers" or "discoverers" of pulmonary blood circulation, Miguel de Servet (1511-1553), physician and theologian, and William Harvey (1578-1657), which in his paper "An Anatomical Exercise on the Motion of the Hearth and Blood in Animals" published in 1628 described blood circulatory system. Ibn Nafis is due to its scientific work called "Second Avicenna". Some of his papers, during centuries were translated into Latin, and some published as a reprint in Arabic language. Significance of Nafis epochal discovery is the fact that it is solely based on deductive impressions, because his description of the small circulation is not occurred by in vitro observation on corps during section. It is known that he did not pay attention to the Galen theories about blood circulation. His prophecy sentence say: "If I don't know that my work will not last up to ten thousand years after me, I would not write them" Sapient sat. Searching the newest data about all three authors: Alauddin ibn Nafis (1210-1288), Michael Servetus (1511-1533) and William Harvey (1628) in the prestige Wikipedia I manage to link several most relevant facts, based on which we can in more details explain to whom from these three authors the glory and the right to call them self first describer of the pulmonary and cardiac circulation belongs. About Servetus and Harvey there is much more data than on ibn Nafis, about which on Google there are mainly references in Arabic and Turkish language, and my four references on Bosnian, with the abstracts in English. Probably the language barrier was one of the key reasons that we know so little about Nafis and so little is written, although respectable professor Fuat Sezgin from Frankfurt in 1997 published comprehensive monograph about this great physician, scientist and explorer, in which papers we can clearly recognize detailed description of the pulmonary and cardiac circulation. Also, I personally published separate monographs about this scientist, and which can be found on www. avicenapublisher.org.

This is a case report of 7 years old boy who presented to us with acute onset of pain and coldness in left leg that appeared during a game and started 3 hours prior to admission in our hospital. Developmental and past medical histories were nonspecific. Physical examination revealed absence of all pulsations in left lower extremity in addition to presence of paralysis of left peroneal nerve. Complete diagnostic investigation was carried out including Seldinger angiography and occlusion of left external iliac artery was confirmed. Embolectomy was performed and hydatid cyst that caused arterial obstruction has been removed from left external iliac and common femoral artery. Follow up examination after 7 days confirmed presence of palpable pedal pulsation with slight lingering paresis of left peroneal nerve that improved with physical rehabilitation exercises. The aim is to present an extremely rare case of primary arterial echinococcosis and to stress upon necessity of including it into differential diagnosis of acute arterial occlusion in regions where this illness is endemic.
