Introduction. Abdominal angina, also known as chronic mesenteric ischemia or intestinal angina, is a rare disease caused by intestinal flow reduction due to stenosis or occlusion of mesenteric arteries. A case of successful treatment of a patient with abdominal angina by percutaneous transuliminal angioplasty of high-grade superior mesenteric artery and coeliac trunk stenosis was presented. Case Outline. A 77-year-old male patient was admitted at our Clinic for severe postprandial abdominal pains followed by frequent diarrhoeas. Extensive gastrointestinal investigations were performed and all results were normal. Multislice computerized (MSCT) arteriography was indicated which revealed ostial celiac trunk and superior mesenteric artery subocclusion. Percutaneous transluminal angioplasty of the superior mesenteric artery and coeliac trunk was done with two stents implantation. Just a few hours following the intervention, after food ingestion, there were no abdominal pains. Six months later, the patient described a significant feeling of relief after food ingestion and no arduousness at all. Conclusion. High-grade visceral arteries stenoses in patients with intestinal ischemia symptoms can be treated by either surgical procedures or percutaneus transluminal angioplasty. In cases when a low operative risk is anticipated, surgical treatment is recommended due to a better anatomical outcome, while percutaneus angioplasty is advised to elderly patients in whom increased operative risks can be expected.

INTRODUCTION The sciatic artery represents the earliest embryological blood supply to the lower extremity. It regresses after the 3rd month of embryologic development. The proximal part of the sciatic artery eventually persists as the inferior gluteal artery. Rarely, however, it persists into adulthood when it is frequently associated with numerous possible complications (aneurysm formation, embolism, nerve compression, rupture, thrombosis). CASE OUTLINE In March 1996, a 48-year-old male was admitted for angiography of the blood vessels of the right inferior extremity, before an elective orthopaedic procedure. Arteriography of the right leg was done in a usual manner through the right common femoral artery in order to get an angiogram of the popliteal trifurcation and crural arteries. However, on the first field we noticed a hypoplastic superficial femoral artery, as well as a huge persistent sciatic artery (PSA) originating from the internal iliac artery running distally and overlapping the deep femoral artery. There were no aneurysm and stenotic changes of PSA. CONCLUSION If clinical condition is stable, follow-ups at 12 months intervals should be done by means of ultrasound. The therapeutic decisions also depend on complete or incomplete PSA.

INTRODUCTION The American otolaryngologist Eagle was the first to describe styloid syndrome in 1937 and the syndrome was named after him (Eagle's syndrome). The original description of two separate syndromes is connected with his name: classical syndrome, which almost constantly occurs after tonsillectomy and carotid artery syndrome, which occurs without tonsillectomy and also in cases when stylohyoid complex compresses the carotid segments and perivascular sympathetic fibers. In the following years, two more syndromes were defined: stylohyoid and pseudostylohyoid, which according to their manifestations, correspond to the genuine classical form. CASE OUTLINE A 40-year old male is presented, with a history of 3-year duration of pains in the upper part of the left side of the neck, in the left eye and its surroundings. Pain occurrences were not regular. Throbbing pains were most often provoked by sudden head movements and neck compression. He was healthy until the onset of these problems. The findings of all examinations were normal. The applied prophylactic therapy, typical for cluster headache, was without any effect. On 64-MSCT (multislice computed tomography), the neck arteries did not show any intraluminal pathology. The styloid processes were of normal length. On the left side, the styloid process tip pressed the internal carotid artery disturbing its longitudinal axis. CONCLUSION In our presentation, the defined lengths of the styloid processes were normal. The medial angulation of the left styloid process was more expressed reaching 63.5 degrees (the right side angulation was normal). Persistent and throbbing pain in the region of the left eye with backward projection suggested compression on the internal carotid artery. Pains were most frequently provoked by head turning and neck compression. 64-MSCT diagnostics enabled us to determine the characteristics of styloid processes and their relation to the internal carotid artery. Improvement was achieved by administration of anti-epileptic (gabapentin) and antidepressant (amitriptyline) drugs.

INTRODUCTION Copper and zinc have significant antiatherogenic effect influencing activity of antioxidant enzyms (giutathion-peroxidase i superoxid-dismutase), mechanism of apoptosis and other mechanisms. Few studies showed increased copper and zinc concentration in atherosclerotic plaque in comparison to normal vascular tissue. AIM The aim of the study was to compare copper and zinc concentrations in carotid artery tissue without significant atherosclerotic changes and human ulcered atherosclerotic plaque. MATERIAL AND METHODS Study was conducted on 66 patients. Carotid endarterectomy due to the significant carotid atherosclerotic changes with cerebrovascular disorders was performed in 54 patients (81.8%). Control group consisted of 12 patients (18.2%) without carotid atherosclerotic changes operated due to the symptomatic kinking and coiling of carotid artery. Operated group consisted of 38 man (62.96%) and 16 woman (37.04%). Control group had the same number of patients: six men (50%) and six women (50%). Preoperatively, all patients were examined by vascular surgeon, neurologist and cardiologist. Duplex sonografy of carotid and vertebral arteries was performed by Aloca DSD 630 ultrasound with mechanical and linear transducer 7.7 MHz. Indication for surgical treatment was obtained according to non-invasive diagnostic protocol and neurological symptoms. Copper and zinc concentration in human ulcered atherosclerotic plaque and carotid artery segment were estimated by spectophotometry (Varian AA-5). RESULTS Average age of our patients was 59.8?8.1 years. For males average age was 76.1 ?9.8 years. And for females 42.4?5.8 years. In group with carotid endarterectomy female patients were significantly younger than male patients (p

Heavily calcified ascending aorta significantly increased morbidity and lethality during open-heart surgery. Cannulation and clamping (partial or total) of severely atherosclerotic ascending aorta can easily cause damage and rupture of aortic wall, with consequential distal (often fatal) embolization with atheromatous debris (brain, myocardium). From June 1998. until June 2000, 11 of 2 136 (0.5%) patients who underwent coronary artery bypass grafting were with the severe atheromatous ascending aorta. The site of cannulation was in the aortic arch in three patients (aorta was occluded with Foley catheter in one case, and single clamp technique was used in the other two cases). The femoral artery was the cannulation site in other five cases. Profound hypothermia, ventricular fibrillation, and circulatory arrest, with no cross-clamping or cardioplegia, were used in three patients. Two patients were operated on with extracorporeal circulation, one in normothermia, on the beating heart, the other in moderate hypothermia, on fibrillating heart. In three patients myocardial revascularization was performed on the beating heart, in normothermia, without extracorporeal circulation. Postoperative course was uneventful in all 11 patients. Neither atheroembolism in the peripheral organs, nor atheroembolism of the extramities occurred. The proposed surgical approaches have the potential to reduce the prevalence of stroke and systemic embolization associated with coronary artery bypass grafting in patients with heavily calcified ascending aorta. This result was achieved due to the applied modifications of standard cardiosurgical technique.

INTRODUCTION Reversible Posterior Leukoencephalopathy Syndrome was introduced into clinical practice in 1996 in order to describe unique syndrome, clinically expressed during hypertensive and uremic encephalopathy, eclampsia and during immunosuppressive therapy [1 ]. First clinical investigations showed that leucoencephalopathy is major characteristic of the syndrome, but further investigations showed no significant destruction in white cerebral tissue [2, 3,4]. In majority of cases changes are localize in posterior irrigation area of the brain and in the most severe cases anterior region is also involved. Taking into consideration all above mentioned facts, the suggested term was Posterior Reversible Encephalopathy Syndrome (PRES) for the syndrome clinically expressed by neurological manifestations derived from cortical and subcortical changes localized in posterior regions of cerebral hemispheres cerebral trunk and cerebellum [5]. CASE REPORT Patient, aged 53 years, was re-hospitalized in Cardiovascular Institute "Dedinje" two months after succesfull aorto-coronary bypass performed in June 2001 due to the chest bone infection. During the treatment of the infection (according to the antibiogram) in September 2001, patient in evening hours developed headache and blurred vision. The recorded blood pressure was 210/120 mmHg so antihypertensive treatment was applied (Nifedipin and Furosemid). After this therapy there was no improvement and intensive headache with fatigue and loss of vision developed. Neurological examination revealed cortical blindness and left hemiparesis. Manitol (20%, 60 ccm every 3 hours) and iv. Nytroglicerin (high blood pressure). Brain CT revealed oedema of parieto-occipital regions of both hemispheres, more emphasized on the right. (Figure 1 a, b, c). There was no sign of focal ischemia even in deeper sections (Figure 1d, e, f). Following three days enormous high blood pressure values were registered. On the fourth day the significant clinical improvement occurred with lowering of blood pressure, better mental state and better vision. There was no sign of left hemiparesis on the 7th day. On the 9th day there were no symptoms or sign of disease. Control brain CT (15th day) was normal. ETHIOPATHOGENESIS Most common causes of PRES are hypertensive encephalopathy [6-8], pre-eclampsia/eclampsia [9-12] cyklosporin A administration [13-22] and uremic encephalopathy [23]. There are several theories about the mechanism for PRES in hypertensive encephalopathy (reversible vasospasm and hyperperfusion) and administration of cyclosporin A (neurotoxic effect). CLINICAL PICTURE Most common symptoms are headache, nausea, vomiting, confusion, behavioural changes, changes of conciousnes (from somnolencia to stupor), vision disturbances (blurred vision, haemianopsia, cortical blindness) and epileptic manifestations (mostly focal attacs with secondary generalization). Mental functions are characterised with decreased activity and reactivity, confusion, loss of concentration and mild type of amnesia. Lethargy is often initial sign, sometimes accompanied with phases of agitation. Stupor and coma rarely occurred. DIAGNOSIS In patients with hypertensive ecephalopathy and eclampsia high blood pressure is registered. Neurological examination revealed vision changes and damages of mental function as well as increased reflex activity. Today, brain MRI and CT are considered the most important diagnostic method for the diagnosis and follow-up of patients with PRES [6]. Brain MRI better detects smaller focal parenhim abnormalities than brain CT.The most often neuroradiological finding is relatively symetrical oedema of white cerebral tissue in parieto-occipital regions of both cerebral hemispheres. Gray cerebral tissue is sometimes involved, usually in mild form of disease. Diagnosis of this "cortical" form of PRES is possible by MR FLAIR (Fluid-Attenuated Inversion Recovery) technique [5]. TREATMENT Therapeutic strategy depends on the cause of PRES and clinical picture. Most important are blood pressure regulation (labetalol, nitroprusid, diuretici), control of epileptic attacs (phenytoin), anti-oedema therapy. (Manitol), induction of vaginal delivery in eclampsia and discontinuation of cyclosporin therapy. In most cases there are no neurological manifestations after the 7th day but some studies showed normalization of clinical finding after one year and more.

The growth of intima media complex is widely accepted parameter in studies that are in relation to the process of atherosclerosis. Increased value of intima-media thickness (IMT) a. carotis communis is the incontestable index of atherosclerosis process in regard to distinct vascular spheres and wider cardiovascular risk. Hypercholesterolemia as the well-known promoter of atherogenesis influence on the increase of IMT. It is established that there is a highly valuable connection (p < 0.001) between the levels of cholesterol and the thickness of IMT. It is also observed a highly significant linear and cubic correlation between the cholesterol and IMT. Concerning the relationship between trigliceride and IMT, it stands out as the highly relevant (R = 0.42; p < 0.001) but the coefficient of correlation is fewer than cholesterol (R = 0.56). Increased value of cholesterol and triglicerides exerts influence on IMT of a. carotis communis simultaneously which leads to highly consequential equation: IMT = 0.005 x TG-0.008 x Chol + 0.28. This mathematics model can be noteworthy if one anticipates effects of primary and secondary prevention.

Background. To assess the early effects, possible risks, and long term results of percutaneous transluminal angioplasty (PTA) of brachiocephalic trunk (BT) and subclavian arteries (SA). Methods. During the period of 11 years, in 92 patients (57 males - 62%, mean age 53,5 ? 7,8 years) 93 PTA of SA/BT were performed; 70 (75%) lesions were stenosis, while 23 (25%) lesions were occlusions with mean diameter stenosis percent of 83,1 ? 6,2%. Clinical indications were: vertebrobasilar insufficiency (n=57), upper limb ischemia (n=40), coronary steal syndrome (n=4) and scheduled aorto-coronary bypass, using internal thoracic artery (ITA) (n=4 asymptomatic patients). Mean lesion length was 22 ? 8 mm. Results. Eighty one (87%) out of 93 lesions were successfully dilated; all of 12 (13%) failures were due to unsuccessful recanalisation of occluded arteries. In 10 patients 10 stents were implanted (2 in BT and 8 in left SA). There were 6 (6.5%) procedural complications: 1 dissection, 1 thrombosis of the left SA, transient ischemic attack in 2 patients, and 2 cases of dislocation of atheromatous plaque from the right SA into the right common carotid artery. During the follow-up of 48 ? 3 months, 16 (20%) restenoses were treated by PTA (n=7) or operatively (n=9). Primary and secondary patency for all lesions treated during 11 years was 87% and 80%, respectively (stenosis: 97% and 89%; occlusions: 58% and 58%). Conclusion. PTA with or without stenting was relatively simple, efficient and safe procedure. It required short hospitalization with low treatment costs. If any of suboptimal results or chronic occlusions were present, the implantation of endovascular stents should have been considered.

Background and purpose: The prospective studies that have compared the outcomes of eversion and standard longitudinal carotid endarcterectomy (CEA) have been few and small and available data to reach definitive conclusions are still scarce. This prospective, non-randomized study sought to compare eversion and standard CEA for early and late mortality and morbidity and the incidence of late restenosis. Methods: Between 1992 and 1997, we performed 2806 CEAs in 2469 patients (2124 eversion CEAs in 1859 patients and 682 standard CEAs in 610 patients). All patients underwent preoperative neurological examination and cervical duplex scanning. Patients were followed up by neurological evaluation and duplex scanning at 1 and 6 months after CEA, and yearly afterwards. Results: Demographics and neurologic inidications for CEA were similar in both groups. Mean clamping time was shorter in the eversion CEA group (13.5±6.1 vs 19.9±19.1 min, P

We presented the case of endovascular treatment of the restenosis of the carotid artery occurring after carotid endarterectomy. We have shown the need of applying the protection systems during the endovascular procedure, in order to prevent the distal embolisation caused by ahterosclerotic debris and/or air.

Introduction Views on the conduct of labor have changed over time, and a significant difference exists in relation to obstetric centers. Objective To assess cost, clinical outcomes and cost-effectiveness of different types of labor in singleton pregnancies. Methods A decision model was used to compare vaginal labor, induced labor and planned cesarean section. All data were taken from the Book of Labor from the University Hospital for Gynecology and Obstetrics 'Narodni Front', Belgrade, Serbia for labors conducted during one month period in 2011. Successful delivery (i.e. labor that began up to 42 gestation weeks, without maternal mortality and the newborn Apgar scores greater than or equal to seven in the fifth minute of life) was considered as the outcome of the cost effectiveness-analysis. To test the robustness of this definition probabilistic sensitivity analysis was performed. Results From a total of 667 births, vaginal labor was conducted in 98 cases, induced vaginal in 442, while planned cesarean section was performed 127 times. Emergency cesarean section as a complication was much higher in the vaginal labor cohort compared to the induced vaginal cohort (OR=17.374; 95% CI: 8.522 to 35.418; p lt 0.001). The least costly type of labor was induced vaginal labor: average cost 461 euro, with an effectiveness of 98.17%. Both, vaginal and planned cesarean labor were dominated by the induced labor. The results were robust. Conclusion Elective induction of labor was associated with the lowest cost compared to other types of labor, with favorable maternal and neonatal outcomes. Uvod Način porođaja se tokom godina menjao, a značajna razlika postoji u pogledu kliničkog centra u kojem se porođaj obavlja. Cilj rada Cilj rada je bio da se procene troškovi, klinički ishodi i troškovna isplativost različitih vrsta porođaja kod jednoplodnih trudnoća. Metode rada Za potrebe rada konstruisano je 'drvo' odlučivanja, radi poređenja spontanog vaginalnog, indukovanog vaginalnog porođaja i planiranog carskog reza. Iz knjige porođaja GAK 'Narodni front' uzeti su podaci o svim porođajima obavljenim u jednomesečnom periodu 2011. godine. Kao ishod analize troškovne isplativosti posmatran je uspešan porođaj, definisan kao porođaj koji je počeo do navršene 42. nedelje gestacije, bez smrtnost majke i sa Apgar skorom novorođenčeta većim ili jednakim 7 u petom minutu po rođenju. Primenom probabilističke analize osetljivosti ispitana je pouzdanost rezultata. Rezultati Od ukupno 667 porođaja, vaginalni porođaj je urađen u 98 slučajeva, indukovani u 442 slučaja, a planirani carski rez 127 puta. Hitni carski rez, kao komplikacija, bio je znatno češći kod žena sa spontanim vaginalnim porođajem nego kod žena koje su porođene primenom indukcije (OR=17,374; 95%CI: 8,522-35,418; p lt 0,001). Indukovani vaginalni porođaj je imao najmanje troškove (461 evro), s efektivnošću od 98,17%. Spontani vaginalni i planirani carski rez su bile skuplje strategije s manjom efektivnošću (dominirane strategije). Rezultati su bili pouzdani. Zaključak Elektivan indukovani porođaj je imao najniže troškove u odnosu na druge vrste porođaja, sa željenim ishodima po majku i dete.

Background. The incidence of recurrent carotid stenosis after primary endarterectomy ranges from 10-34%. We presented our four year experience and comparing reoperation versus endovascular treatment. Methods. In period from 2001 to 2005, 50 patients, 37 men and 13 women, were treated surgically and endovascular due to restenosis. Results. There were no minor or major stroke, death and myocardial infarction periprocedural and in first 30 days in either group. In endovascular group one patients 3,17% had transient ischemic attack and two patients 11,76% in surgical group. One patient died from myocardial infraction in follow up in surgical group. There were no restenosis >50% in endovascular group, two patients have restenosis >50% in surgical group. Conclusions. Endovascular treatment of carotid artery restenosis represents a safe and efficient way of treatment, connected with minor number of serious complications than redo operation.
