[Surgical aspects of liver resection based on 5 years' data].

From 1988 to 1993 thirty liver resections were performed in thirty patients. Eight were operated for suffering from hepatocellular carcinoma, four from metastasis of colon's adenocarcinoma, five for great hemangiomas and the rest for focal liver changes. Right lobectomy was performed in six cases, as well as two trisegmentectomies and two left lobectomies while segmentectomies in the rest. Periopretive mortality occurred in two cases as two patients died because of postoperative thrombosis of vena portae and massive gastrointestinal bleeding. Recidive of malignant tumors was established in five patients after year and in other five till the second year. Benign tumors are without recidives. Later resection is a safe procedure with a considerable selection of patients, with use of latest technical conveniences, application of grafts on branches of vena portae and with routine application of intraoperative ultrasonography. The paper contains diagnostical postulates, surgical techniques and anatomic and morphologic types of resection.

[Vascular aspects of experimental transplantation of the kidney in dogs].

Organ transplantation is predominantly vascular surgical procedure. Vascular aspects of renal transplantation are important in all surgical phases of this procedure: --donor-nephrectomy (living-related or cadaver nephrectomy)--include nephrectomy undamaged kidneys, each with good length of renal artery (with or without aortic patch), renal vein (with or without caval patch) and ureter --organ-ex situ-surgery (bench surgery) sometimes is necessary after cold perfusion with Collins solution --implant surgical procedure, which include--dissection of recipient vessels (localisation.) --venous anastomosis (type and technique) --arterial anastomosis (type and technique) --use of vascular grafts (autografts or alografts) for kidney revascularisation during implantation (???) In the period 1987-1988, in our Experimental Surgery Unit a total of 20 dogs were operated (experimental kidney autotransplantation) under the same surgical team. The aims of those experimental autotransplantations were: training of the surgical team for routine human renal transplantations and usefulness of vascular grafts (autografts or allografts) for kidney revascularisation. We divided animals into the three groups: The first group (5 dogs)--revascularisation using AUTOVENOUS grafts The second group (5 dogs)--revascularisation using ALLOGRAFTS (Dacron or e-PTFE-Goretex grafts) The third group (10 dogs)--direct revascularisation without vascular grafts (control group) The best results were in the third group (no early vascular thrombosis) especially with end-to-end arterial anastomosis (we prefer it) and end-to-side venous anastomosis. Unfortunately in the second group, results were bad (vascular anastomotic thrombosis in the all cases during the first 48 hours).(ABSTRACT TRUNCATED AT 250 WORDS)

[Results of surgical treatment of ruptured abdominal aortic aneurysms].

This paper analyzes results of 5-year surgical treatment of patients with ruptured abdominal aorta aneurysms (1991.-1995.) at the Clinic for Vascular and Transplantation Surgery of the Institute of Surgery in Novi Sad. 105 patients with abdominal aorta aneurysm underwent surgery, whereas in 31 patients there was a suspicion of rupture and it was confirmed by US and CT examination. One of basic factors to decrease mortality in these patients is early diagnosis and surgery before hemorrhagic shock occurs. Results in hemodynamic stabile patients with blood pressure over 100 mmHg and regular diuresis are much better with mortality of 20%. In order to estimate the correlation of hemodynamic state and outcome of the operation, patients were divided into three groups--hemodynamic stable with blood pressure over 100 mmHg and regular diuresis at admission: hemodynamic unstable patients with signs of mild or moderate shock and blood pressure under 100 mmHg and without initial diuresis which was regulated at the beginning of therapy and hemodynamic unstable patients in severe shock and unmeasurable blood pressure. The highest survival rate (10% mortality) and the least complications occurred in the first group of patients. The total mortality of patients after surgery was 48.48%. Timely diagnosis, suspicion of rupture and adequate first and with urgent transfer to a competent surgical institution are key factors in treatment of this disease and its outcome.
