INTRODUCTION: In-hospital mortality of acute aortic type III dissection ranged about 12%. Complicated dissections represent about 18% of all cases, and require open surgery or TEVAR. More morphological predictors of in hospital mortality are needed to differentiate patients who should be selected for immediate, surgical or endovascular intervention.; METHODS: From January 2009 to December 2014, 74 patients with acute aortic type III dissection were enrolled at Clinic of Vascular and Endovascular Surgery in Belgrade Serbia and retrospectively analyzed. Every MSCT was observed in regard to morphologic characteristics of dissection.; RESULTS: By analyzing morphologic parameters in patients between survival and non-survival group only localization of intimal tear showed statistical significance (p=0,020). The size of the intimal tear didn't reach statistical significance with the tendency of doing so in a larger sample of patients (p=0,063) with the cut-off value of 9.55mm. The shape of the true lumen was on the border of statistical significance (p=0,053).; CONCLUSION: Inner curvature intimal tear localization, huge intimal tear as well as elliptic shape of the true lumen together should raise awareness to a subgroup at risk for in hospital mortality. More liberal endovascular treatment in this subgroup of patients is advocated.

Aim. Horseshoe kidney is the most common congenital kidney anomaly, occurring in 0.15-0.25% of all newborns. A medial fusion of the kidneys, mostly anteriorly to the aorta, is the main characteristic of this anomaly. The co-existence of abdominal aortic aneurysm (AAA) and horseshoe kidney is rare, occurring only in 0.12% of patients. The aim of this paper is to define the optimal management of patients with AAA associated with the horseshoe kidney. Methods. This paper presents the analysis of patients operated at the Clinic for Vascular and Endovascular Surgery of the Clinical Center of Serbia in Belgrade due to AAA associated with the horseshoe kidney as well as the analysis of the previously published literature data regarding this topic. Results. Between 1985 and 2011, data were collected retrospectively on 25 patients with the horseshoe kidney who underwent aortic surgery. Out of them, 6 patients had aortoiliac occlusive disease and 19 patients had aortic aneurysm. More detailed analysis of the aneurysmatic group was performed. Among them there were 16 male and three female patients, with the average age of 63.8 (50-76) years. Two patients had type IV of thoracoabdomial aortic aneurysm (TAA) according to Crawford-Saffi classification, while 17 had infrarenal abdominal aortic aneurysms. There were 15 elective and four urgent procedures due to aneurismal rupture. The presence of the horseshoe kidney was detected in 16 patients before surgery (84.2%) by means of Duplex ultrasonography, angiography, computed tomography and intravenous urography. Multiple renal arteries were presented in 12 (63.2%) cases. A transperitoneal approach was used in 16 cases with abdominal aortic aneurysm, while left retroperitoneal approach with partial extrapleural removal of the 11 th rib was performed in two cases of thoracoabdominal aneurysm and in one patient with AAA. In 18 cases, kidney tissue transection was successfully avoided with vascular graft placement beneath the horseshoe kidney. In one case only, the division of the renal isthmus was performed. In all 12 cases with detected anomalous renal arteries, their reattachment into vascular graft has been performed. Two patients (10.5%) died during perioperative period. One of them had ruptured type IV TAA. Seventeen patients who survived were followed from one to twenty years (mean 6.6 years). During the follow up period we lost track of 4 patients. In this period there were no signs of graft occlusion, or renal failure. Conclusion. Repair of an abdominal aortic aneurysm in the presence of the horseshoe kidney is a truly particular surgical challenge. It is associated with three main problems: choice of the surgical approach; the procedure regarding kidney isthmus preservation as well as recognition and reattachment of all significant anomalous renal arteries.

Aim. The aim of this paper was to determine the role of ultrasonographic examination in acute progressive thrombophlebitis (APT) of great saphenous vein (GSV) and its impact in considering indications for urgent surgical treatment. Methods. In this retrospective study, out of 141 consecutive patients operated due to APT of GSV above the knee, 63 were examined by ultrasonography prior surgery. Results. Out of 63 operated patients, in 38 duplex ultrasonography (DUS) revealed that proximal level of phlebitic process was more than 5 cm higher than the one found during physical examination (60.3%). In this group, the mean difference between DUS and clinical finding was 8.5±3.5 cm. In 25 patients there were no differences greater than 5 cm found between DUS and physical examination (39.7%). There was statistically highly significant difference between DUS and physical examination findings (χ 2=6.5, P<0.01). Conclusion. This study revealed significant difference between ultrasonographic and physical findings in patients with APT of GSV. DUS presented as reliable diagnostic method in examining, course-following and making decision for operative treatment of these patients.
