[Arterial aneurysms]. / Arterijske aneurizme.

The author analysed etiology, morphology, localization, symptomatology, diagnostics and surgical methods of treatment in 63 patients with 81 arterial aneurysms. Arterial aneurysms are not rare in vascular pathology. Most of them are atherosclerotic etiology (62%). Abdominal aorta is the most frequent localization (49%). Symptomatology and clinical findings depend on the localization, size and complications. Echosonography, with clinical finding, has presented the most accurate diagnostic procedure. Surgery is the method of the treatment of such patients, but the optimal method is the aneurysmectomy or resection of aneurysm with arterial reconstruction.

[Early prognosis of free venous autograft in common bile duct reconstruction. Experimental study--first phase]. / Rana prognoza slobodnog autovenskog grafta kod rekonstrukcije duktus holedohusa. Eksperimentalni rad--prva faza istrazivanja.

Experiments were carried out on 25 grown-up dogs of both sex in general anesthesia. The supraduodenal part of the choledochus was excised and the reconstruction of the defect with a free venous autograft was made by an end to end anastomosis without use of a transitory or permanent prosthesis. The experimental animals were observed for 60 days, during which period they were checked clinically, biochemically and radiologically. After this period the animals were sacrificed and surgical peroperative control and sampling of material for histological study were made. Out of 25 experimental animals 18 (72%) survived a period of 60 days and 7 dogs died. On autopsy it was found that the cause of death in all animals was biliary peritonitis, but in only one case due necrosis of the graft. The values of bilirubin concentration at the end of the experiment showed almost normal level, but the values of the alkaline phosphate activity and transminase showed significant increased values. Intravenous biligraphy showed significant excretion of the contrast material, freely passing the graft, which was dilated due to stenotic changes of the distal anastomosis. After sacrificing the animals we found: the graft increased length, diameter, thickness wall and stenosis of the distal anastomosis. By histological exploration we found in the liver the signs of the biliary stasis and in the grafts substitution of its endothelium by biliary epithelium. Free venous autograft used as a substitute in the reconstruction of the bile duct which survived 60 days postoperatively, remained transient but with changes in the sense of elongation and dilatation caused by the stenosis od distal anastomosis. Histologically the grafts were entirely bridged by biliary epithelium.

In a group of 63 patients with 81 arterial aneurysms the author analysed the etiology, morphology, location, clinical diagnosis and treatment. Arterial aneurysms are not so rare phenomenon in vascularly pathology, most of them there are atherosclerotic etiology (62%), abdominal location (49%), symptomatology and clinical findings depends from location, size and complications. Ehosonography with clinical findings, especially for aneurysms of abdominal aorta, are certain diagnostic procedures. The method of the treatment of such patients is only surgical, but the optimal method is the aneurysmectomy or resection of the aneurysm with the reconstruction of the artery.

[Tumors of the retroperitoneum]. / Tumori retroperitoneuma.

Authors present 13 patients with tumors of the retroperitoneal space. Primary tumors were revealed in 84.6%, malignant tumors in 92%, mesodermal source in 100%, liposarcomas in 30%, Operative treatment was undertaken in all patients, radical operation in 5 patients, radical operation with intervention on the surrounding structures in 4 patients, reduction tumor in one and biopsy in 3 patients.

[Reconstruction of the common bile duct with a free venous autograft (experimental work - preliminary communication)]. / Rekonstrukcija duktus holedohusa slobodnim autovenskim graftom (eksperimentalni rad - preliminarno saopstenje).

In seven dogs, the authors performed a resection of the supraduodenal part of the main bile duct, 15-2 cm. in length. The arising defect was bridged over with a free autovenous graft taken from the exterior jugular vein (T-T anastomosis), without using a temporary or permanent prosthesis. The animals were followed-up 60 days and the sacrificed. Three dogs perished: the first one on the third day due to intoxication, the second dog on the thirteenth day because of anastomosis' disruption and consequent biliary peritonitis, and the third one on the eighteenth day of unknown causes. In the immediate postoperative course the values of the bilirubin and alkaline phosphatase were increased while those of transaminase were not significantly altered. These values began to normalize during the third week. An intravenous biliography was made on the sixtieth day showing a normal filling of the gallbladder, with an orderly visualization of hepato-choledochus and its correct transit, but with stenosis at the distal anastomosis. Macroscopically, the graft appeared slightly enlarged in length and diameter due to the mentioned stenosis. Histologically, the graft took on an appearance similar to the main bile duct, while its endothelium was completely replaced by biliary epithelium. An answer about the viability of this autovenous graft to serve as a substituent of a normal common bile duct is to be expected with further experimental work.
