[Renal failure in surgery of abdominal aorta aneurysms].

The authors analyse the experience in operations for resection of an aneurysm of the abdominal aorta in 70 patients, which were performed at the Vishnevsky Institute of Surgery, AMS of Russia, from 1983 to 1991. Preoperative examination revealed renal insufficiency in 8 (11.4%) patients. Resection of the aneurysm of the abdominal aorta with one-stage prosthetics of the renal arteries was carried out in 10 cases. To prevent ischemic damage to the renal parenchyma and acute renal insufficiency, local methods of kidney protection (isolated cold perfusion--2 and normothermic aorto-renal perfusion--2) were applied in 4 of 70 cases. The work discusses the methods of kidney protection and the indications and contraindications for their use, and factors promoting the development of postoperative renal insufficiency. Postoperative complications are shown and their causes are identified.

[Ischemic stroke and the ways of compensation of cerebral circulation in patients with nonspecific aorto-arteritis with lesions of the brachiocephalic arteries].

In patients suffering from nonspecific aortoarteritis associated with impairment of the common carotid arteries, cerebral blood flow is compensated for at the expense of an increase of the volumetric blood flow in the vertebral arteries. During the first three years since the onset of the first disease symptoms, the blood content in the basin of the internal carotid arteries is reduced. Brain strokes occur most frequently within that period. They mostly develop without any preceding transitory ischemic attacks. The origin of neurological symptomatology depends to a considerable measure on the condition of the anterior and posterior communicating arteries.

[Surgical tactics in combined lesions of the aortic arch and its thoraco-abdominal segments in nonspecific aortoarteritis].

Seventy-one patients with unspecific aortoarteritis and affections of the aortic arch and its thoracoabdominal segment were treated in the period between 1984 and 1989. All the examined patients had different variants of affection of the brachiocephalic arteries, in 57 (80.3%) of them there was a coexistent affection of the thoracoabdominal segment of the aorta, and in 14 (18.7%) coexistent affection of the abdominal aorta and the lower limb arteries. Operations were conducted on 56 (78.8%) patients. Reconstruction of the brachiocephalic arteries was carried out in 12 (21.4%), of the thoracoabdominal segment of the aorta and the renal arteries in 30 (53.6%), and of the abdominal aorta and lower limb arteries in 9 (16.1%) cases. Five (8.9%) patients underwent two-stage correction of the blood flow in the branches of the arch of the aorta and its thoracoabdominal segment. The clinical picture, the volume of the affection, the methods of examination, and techniques and the results of reconstructive operations are described in detail. The authors present their point of view on the performance of surgical treatment in stages in coexistent lesions differing in volume.

[Surgical tactics in nonspecific aortoarteritis of the thoracoabdominal region].

Sixty-six patients with nonspecific aortoarteritis of thoracoabdominal localization were treated at the department of vascular surgery of the Vishnevsky Institute of Surgery, AMS USSR from 1984 to 1989. Operations were performed on 49 (74.9%) patients. Percutaneous angiodilatation of the renal arteries was conducted in 3 (4.5%) patients. Nonoperative treatment was carried out in 14 (21.2%) patients. In view of concurrent affection of the branches of the arch of the aorta, reconstructive operations were performed in 16 (24.2%) cases on the brachiocephalic trunks: aorto-biocarotid prosthetics (6), aortocarotid prosthetics (1), subclavian-carotid autovenous prosthetics (6), carotid-subclavian autovenous shunt (2), carotid endarterectomy (1). Reconstructive operations on the brachiocephalic trunks were preceded by reconstruction of the arteries in 5 (7.6%) cases and were conducted after correction of the blood flow in the thoracoabdominal segment in 2 (3%) cases. In 9 (13.6%) patients only the brachiocephalic trunks were reconstructed. A total of 42 reconstructive interventions on the thoracoabdominal segment were carried out on 40 (60.6%) patients, in 35 (87.5%) correction of the blood flow in the visceral branches and renal arteries was performed simultaneously. The surgical tactics suggested by the authors and the results produced by it are discussed in detail.

[Indications for and the methods of revascularization of visceral branches in aorto-femoral reconstruction].

The work presents data of 774 patients with occlusing injuries of the abdominal aorta and arteries of lower extremities subjected to aorto-femoral reconstructions. In 546 of these patients (70.5%) there were different variants of injuries of visceral branches. A detailed analysis of the clinical picture of injuries of the visceral branches is presented related with the injury volume, etiology of the occlusing process and coexistent arterial hypertension. The authors have an experience with 169 observations of revascularizations of visceral branches during aorto-femoral reconstructions. Reconstruction of the inferior mesenterial artery was made in 134 cases, that of the celiac trunk of the superior mesenterial artery-in 35 cases. A detailed description of indications to correction of the visceral branches blood flow in aorto-femoral reconstructions is presented as well as the methods of revascularization of the visceral arteries.

[The initial experience of using pulse therapy with cyclophosphane and 6-methylprednisolone in patients with acute and subacute stages of nonspecific aortoarteritis].

The authors summarize the first experience gained with the use of pulse therapy with cyclophosphamide and 6-methylprednisolone in 18 patients with acute and subacute nonspecific aortoarteritis. Remission attained in 16 patients was attended by a decrease in objective criteria of the process acuity. It has been noted that duration of the remission was inversely proportional to the time of the inflammatory anamnesis. Provided the patients manifested exacerbation of the process, repeated courses of pulse therapy were conducted.

[Indications for the revascularization of visceral branches of the abdominal aorta in aorto-femoral reconstruction].

Affection of the visceral branches of the abdominal aorta was diagnosed in 546 of 783 patients subjected to aorto-femoral reconstructions. The clinical picture of affection of the visceral branches is analysed according to the extent of their involvement and the genesis of the occlusive process. The authors possess experience in 169 cases with revascularization of the visceral branches in aorto-femoral reconstructions. Reconstruction of the inferior mesenteric artery was carried out in 134 cases and reconstruction of the celiac trunk and the superior mesenteric artery--in 35 cases. Retrospective analysis of the frequency and severity of gastrointestinal complications in the immediate and late-term postoperative periods allowed the authors to formulate the indications for and elaborate the optimum extent of reconstruction of the visceral branches depending on the character of their affection and the course of the occlusive process.
