The surgical anatomy of the perforating branches of the anterior choroidal artery.

BACKGROUND: The available information about certain microanatomic features of the AChA perforators is incomplete. Precise knowledge of these vessels is necessary to understand the consequences of their occlusion and to safely operate in their region. METHODS: The AChA perforators were microdissected and examined under the stereoscopic microscope in 10 vascular casts and in 20 hemispheres injected with india ink or radiopaque substance. RESULTS: The perforating branches ranged in number from 2 to 9 (mean, 4.6) and in diameter between 90 microm and 600 microm (mean, 317 microm). The most proximal perforator arose 3.2 mm on average caudal to the AChA origin. The most distal (capsulothalamic) perforator varied in size from 200 microm to 610 microm (mean, 431 microm). One or more of the perforators always originated from the AChA (100%), but some of them also from the uncal (33.3%) or parahippocampal branch (10%) of the AChA, either as individual vessels only (70%) or from common trunks (30%). The perforators gave off the peduncular (20%), optic (23.3%), or uncal side branches (26.7%). CONCLUSIONS: Our findings concerning the origin, position, number, size, branching, penetration site, and relationships of the AChA perforators gave the anatomic basis for safe operations in patients with AChA aneurysms or mediobasal limbic epilepsy.

Unruptured congenital aneurysm of the right sinus of Valsalva. Dissecting into the interventricular septum.

We report the case of a congenital aneurysm of the right sinus of Valsalva dissecting into the interventricular septum in a 21-year-old man. This condition was diagnosed by echocardiography and magnetic resonance imaging. In particular, transthoracic and transesophageal color-coded Doppler echocardiography showed that there was no communication between the aneurysm and the surrounding heart chambers. The findings were confirmed by angiography. Heart enlargement and other symptoms and signs of heart failure indicated surgical repair of the lesion. Early postoperative dehiscence of the sutured orifice was accurately diagnosed with Doppler echocardiography and angiography. Reintervention was successful in filling and sealing the septal cavity. This case confirms the reported difficulties in the surgical correction of aneurysms of sinus of Valsalva lying within the interventricular septum.

[Results of a multi-year study of persons with transplanted kidneys].

The authors review their results of five year follow up of renal transplantation. They summarised the results of treatment with three immunosuppressive regimens. There is an analysis of rejection episodes, recurrent glomerulonephritis, infections, surgical complications, a median graft as well as patient survival and other patterns of complications of renal transplantation.

[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.

[Transplantation of the kidney at the medical school in Novi Sad--3 years' experience of an interdisciplinary transplantation team].

The interdisciplinary transplant team on Medical faculty--Novi Sad is formed at the beginning of the 1986, and first successfully cadaver binephrectomy was performed in April 1986, and kidneys was transported in Transplant Centre in Belgrade. The first human renal transplantation with cadaveric kidney was performed 20, May 1986, and result was excellent. The first human renal transplantation with living related kidney was performed 27, Sept 1986, and result also was excellent. During the last three years our transplant team performed 32 renal transplantations. cadaveric kidney transplantations - 25 living-related kidney transplantation - 6 kidney autotransplantation - 1 Our Concept and organisation of interdisciplinary transplant team in Medical Faculty--Novi Sad is the very efficacy model of organisation and at the same time the cheapest solution. In this paper we discuss our organization of human renal transplantation, and technique of donor-neprectomy (cadaveric and living-related) and cold perfusion of kidney with Collins solution. Our rules for implantation are shown as the Algorythm. At the end of this paper we present our results, based on three year's experience and list of the members of our interdisciplinary transplant team.

[Multiorgan explantation].

In this paper, we discuss an ALGORYTHM of multiorgan explantation, including strategy, alternate technical principles with especially circumstances during this surgical procedure and rules for functional evaluation of human organs during and after explantation.

[Partial heterotopic and total orthotopic transplantation of the liver in dogs].

From 1983 to 1988 on the Department for Experimental Surgery 20 preservations of the liver has been done, with ice cold Euro- Collins and Ringer solutions, either with in situ or with on banch technique after fast expantation. On five dogs standard 55% left hepatectomy has been done and the right side preserved in situ. Partial heterotopic liver transplantation to the right iliac fossa was performed on five dogs. Total vascular exclusion of the liver and extracorporal inierior vena cava and jugular vein by pass with assisted circulation was performed on one dog, without assistance on four dogs. Total orthotopic liver transplantation was performed on two dogs. The surgical team practiced the technique of liver transplantation in experiment and liver resection with in situ technique and on banch technique.
