[Indications for carotid endarterectomy and its outcomes].

The paper analyzes a correlation between the sonographic and morphological characteristics of the structure of atherosclerotic plaques and the severity of cerebrovascular insufficiency. This significantly expands indications for surgical treatment in patients with carotid atherosclerosis. In the authors' opinion, not only the degree of carotid stenosis, but also the structure of a plaque is an important criterion for assessing indications for surgical treatment. The outcomes of carotid endarterectomy are comparatively evaluated in relation to the mode of carotid plastic repair. A role of intraoperative cerebral oximetry is shown.

[Surgical treatment of aneurysms of unpaired visceral branches of the abdominal aorta].

Aneurysms of unpaired visceral branches of the abdominal aorta are rare diseases but they are dangerous for life. Russian Research Center of Surgery RAMS has an experience of diagnosis and surgical treatment of 23 patients with aneurysms of the celiac trunk (2), superior mesenteric artery (4), inferior mesenteric artery (1), hepatic artery (4), splenic artery (7), gastroduodenal artery (2), inferior pancreatoduodenal artery (1), multiple aneurysms of celiac trunk and superior mesenteric artery (2). 21 of 23 patients were operated. 20 patients were discharged with complete recovery. 1 (4.8%) patient died due to gastroduodenal bleeding 4 months after surgery. The results show that patients with aneurysms of unpaired visceral branches of abdominal aorta require surgical treatment.

[Surgical treatment of carotid chemodectomas].

49 patients have been examined and 38 of them operated in RRCS RAMS for carotid hemadectomas (CH). CH is a rather rare tumor developing from the carotid gland locating in bifurcation of the common carotid artery. It is slowly growing tumor which is scantily active and rarely metastasizes. In 35 of the 38 operated patients radical ablation of the tumor was carried out. In the rest 3 patients radical removal of the tumor was impossible due to its dissemination and malignancy. The classification was used according to which all the tumors were distributed in 3 groups in dependence on the character of their growth. The basic principle of their division was the relation of CH to the carotid arteries. The use of this classification allowed to define individual surgical tactics. As a result of the treatment 97.4% of the patients were discharged with improvement. During the follow-up period (94 +/- 5 months) there were no relapses detected in these patients.

[The use of angioscopy in the reconstructive surgery of vascular diseases of the lower extremities].

On the basis of the literature data and original research, the value of angioscopy in reconstructive surgery of vascular diseases of lower extremities is analyzed with a report of clinical application of intraoperative angioscopy. Practical recommendations for the use of angioscopy as a method of intraoperative control of quality of reconstructive operations on lower limbs vessels are provided.

[Bilateral malignant carotid chemodectoma].

A clinical case of carotid chemodectoma is reported. Unique character of this case consists in combination of rare manifestations of this disease in a patient (malignancy, bilateral location). Summarizing their own experience and analysis of literature data the authors give recommendations for diagnosis and management of such patients.

[Intraoperative angioscopy in vascular reconstructive surgery].

Based on the data available in the literature and their own findings, the authors analyzed the value of angioscopy in the reparative surgery of low limb vessels. Some cases of clinical application of intraoperative angioscopy are described and guidelines for the use of angioscopy as an intraoperative control of the quality of reparative surgery on low limb vessels.

[35 years of experience in reconstructive operations in surgery of vasorenal hypertension].

Reconstructive surgery was performed in 1148 patients with renal hypertension in the period from 1961 to 1996. Extracorporeal microsurgical correction with subsequent kidney autotransplantation was used in case of the lesions of the renal arteries branches. In 161 (14%) of the patients the result was unsatisfactory. The reasons of unsatisfactory results were the following: uncorrected stenosis of the contralateral renal artery (43%), nephrosclerosis of the contralateral kidney (26%), unknown reasons (31%). The long-term results have been followed up in 769 (67%) of the patients in the period for 135 +/- 4 months after the surgery. In 546 (71%) of the patients positive results persisted. The average time of symptomatic recurrence was 74 +/- 6 months after the surgery. Restenosis was the reason of recurrence in 61 (57%) of the patients. Based on these results the following recommendations are postulated: in atherosclerosis--the transaortic endarterectomy from the opening of the renal artery; in fibromuscular displasia--renal artery resection with end-to-end anastomosis; in nonspecific aorcic arteritis--bypass operations.

[Autologous vein bypass surgery in situ for reconstructive surgery of blood vessels of the leg].

The paper analyzes the authors' own experience with femorodistal bypass surgery in situ in patients with lower extremity vascular occlusive lesions. The patent distal bed and the intact superficial saphena are obligatory conditions for these operations. The paper details the surgical procedure, criteria for adequate blood flow recovery, the spectrum and incidence of complications in the immediate postoperative period. The beginning of the paper presents a brief review of the data available in the literature, which shows the present status of this worldwide problem.

[Results of surgical treatment of chronic abdominal ischemia].

The immediate results of surgical treatment for chronic abdominal ischemia were studied in 112 patients. The late-term results were studied in follow-up periods of 6 months to 20 years in 105 (95.5%) patients treated by operation and in 45 patients who were not operated on. In the immediate postoperative period, positive results were recorded in 104 (92.8%), no changes were found in 4 (3.6%) patients, and fatal outcomes occurred in 4 cases (3.6%). In the late-term postoperative period the results were positive in 79 (75.2%) patients, no changes were produced in 3 (2.9%), the disease recurred in 21 (20%) patients, and 2 (1.9%) patients died. Actuarial analysis showed the late-term results of surgical treatment to be higher by 40.8% in a 5-year follow-up period and by 27.7% in a 10-year follow-up period (69.93 +/- 5.8% in a 5-year period and 36.69 +/- 9.43% in a 10-year period) than in nonoperative treatment (29.16 +/- 6.75% and 8.97 +/- 4.27%, respectively) in P less than 0.01.

[Current problems of reconstructive surgery in patients with lesions of the visceral branches of the abdominal aorta].

This work is devoted to a current topic of vascular surgery, treatment of patients with such severe ailments as vasorenal hypertension and chronic abdominal ischemia. These diseases are secondary to the affections of the visceral branches of the abdominal aorta. The possibilities for their complete cure by means of reconstructive surgery are discussed. Results of surgery are analysed in 830 patients with affection of the visceral branches of the abdominal aorta, in whom reconstructive operations were performed: in 774 patients on the renal arteries and in 56 patients on unpaired visceral branches. Specific reconstructive operations are discussed in terms of their etiology and clinical manifestations. The immediate and long-term postoperative results were studied in these patients with the follow-up period lasting to 25 years. The necessity to assign such categories of patients to reconstructive surgery is demonstrated.

[Choice of the surgical intervention method in patients with chronic abdominal ischemia].

An experience with the treatment of 111 patients with chronic abdominal ischemia resulting from the alteration of the unpaired visceral branches of the abdominal aorta is presented. In 74 of the patients 77 operations have been performed. Criteria for the choice of the method of surgery in such patients are proposed depending on etiology, localization and spread of the pathological process. Positive results were obtained in 76% of the patients.
