[Surgical treatment of ischemic colitis in patients with abdominal aortic aneurysm].

The authors suggest an original method for revascularization of the inferior mesenteric artery for the prevention and treatment of ischemic colopathy in operative treatment of abdominal aortic aneurysm. The essence of the method consists in shunting the blood flow from the channel of the celiac trunk by anastomosing the right gastroepiploic artery with the inferior mesenteric artery by the end-to-end techniques. Topographoanatomical studies of the right gastroepiploic and inferior mesenteric arteries were conducted on 22 cadavers for experimental substantiation of the suggested method. Besides that, selected angiograms of the celiac trunk and its branches were studied in 50 patients. The suggested method for revascularization of the inferior mesenteric artery in resection of aneurysm of the abdominal aorta with intraluminal prosthetics was applied in eight patients with good results.

[Reconstructive surgery of abdominal aortic aneurysm].

The authors have developed the methods for performance of a reconstructive operation for abdominal aortic aneurysms which permit to avoid prolonged clamping of the abdominal aorta. On the basis of the results obtained, a conclusion of the high effectiveness of these methods has been drawn.

[Limb revascularization through the deep femoral artery in atherosclerotic femoropopliteal occlusions].

The article analyses the results of examination and surgical treatment of 101 patients who were subjected to 105 reconstructive interventions on the deep femoral artery (DFA). Angiography showed affection of the orifice and beginning (up to 2 cm) of the DFA in 57.14% of cases, for a distance of 2-6 cm in 24.76%, and for a distance of more than 6 cm in 18.1% of cases. Arterial outflow was found to be excellent in 52.38%, good in 21.9%, satisfactory in 19.05%, and poor in 6.67% of cases. According to the findings of ultrasonic dopplerometry the changes of regional hemodynamics were most marked in III degree ischemia of the limb. Endarterectomy with the formation of a new communication between the superficial and deep femoral arteries was conducted in 14 cases, autovenous profundoplasty in 21, autoarterial profundoplasty in 35, autoarterial prosthetics of the DFA in 14, and autovenous DFA prosthetics in 21 cases. In 87.13% of patients the operation on the DFA was combined with lumbar sympathectomy. Choice of the method for DFA reconstruction on the basis of morphofunctional appraisal of the occlusive-stenotic process, the condition of collateral circulation and the outflow paths made it possible to achieve favorable results both in the immediate and late-term postoperative periods in more than 73% of cases.

[Selection of the approach to the surgical treatment of diseases of the abdominal aorta].

The article discusses results of using in clinic different operative accesses in surgical treatment of occlusive-stenotic injuries and aneurysms of the abdominal aorta in 224 patients. Full medial laparotomy was used in 22 patients, extraperitoneal access--in 27 patients, extraperitoneal C. Rob access--in 122 patients, extended +thoraco-phreno-lumbotonic access--in 5 patients, the developed extraperitoneal access--in 48 patients. The advantages of the proposed method as compared with the pararectal method and C. Rob's one were experimentally confirmed. Choice of the operative access depending on the kind and spread of the pathological alterations in the abdominal aorta and the presence of complications were shown to be expedient.

[Immediate results of reconstructive operations in arteriosclerosis obliterans of the iliac and femoral arteries].

The work generalizes the immediate results of restoration of the main and collateral blood flow in 240 patients with arteriosclerosis obliterans of the iliac and femoral arteries. The outcomes of surgical treatment were judged according to the clinical and ultrasonic evaluation of regional hemodynamics. The results were found to be good in 84 (35.0%), satisfactory in 104 (47.5%), and poor in 42 (17.5%) patients. The results of operations on the iliac and femoral arteries are shown separately, as well as the results of surgery in their combined lesions. Thromboses of the reconstructed arteries and prostheses were encountered in 10 (4.17%), hemorrhages in 8 (3.33%), wound infection in 16 (6.67%), and venous thromboses in 4 (2.5%) patients. For the prevention of thromboses of the deep veins the author claims dosed physical exercises on a constructed training apparatus to be advisable. Amputation of the extremity was carried out in 10 (4.17%) patients because surgical correction of the blood flow proved ineffective and specific complications occurred.

[Surgical tactics in obliterating atherosclerosis of the iliac and femoral arteries].

The article discusses the indications for and the choice of the method of reconstructive operations in patients with arteriosclerosis obliterans of the iliac and femoral arteries. It is based on the analysis of the results of examination and surgical treatment of 240 patients. Radiocontrast angiography and ultrasonic dopplerometry were applied for morphofunctional characteristics of regional circulation. The study showed that the surgical tactics in this category of patients should be determined by the severity of ischemia of the extremity, the character, localization, and length of the arteriosclerotic process, the state of the inflow and outflow passages, the condition of collateral circulation in the internal iliac and deep femoral arteries, and the presence and severity of concomitant diseases. The developed differentiated approach made it possible to achieve positive results of treatment in the immediate postoperative period in 82.50% and in the late-term follow-up periods in 77.38% of patients.

[Ultrasonic evaluation of regional hemodynamics in arteriosclerosis obliterans of the iliac and femoral arteries].

Regional hemodynamics was studied in 120 patients with atherosclerosis obliterans of the iliac and femoral arteries by ultrasonic Dopplerometry. Regional malleolar systolic pressure, malleolar-upper arm index, and regional systolic perfusion pressure deficit (RSPPD) were determined by an elaborated method. The authors analyse the values of regional hemodynamics according to the severity of the trophic disorders and type of the occlusive lesion of the iliac and femoral arteries. It was established that, being an integral characteristic, RSPPD allows the degree of limb ischemia to be characterized quantitatively most informatively with consideration for the condition of the central hemodynamics.

[Surgical tactics in aneurysm of the abdominal aorta].

The results of treatment of 164 patients with aneurysms of the abdominal aorta are summarized. Of these patients, 95 were operated on. Realization of the developed tactics of treatment permitted to reduce the incidence of postoperative complications 3.8-fold, and lethality--5.3-fold.

[Regional hemodynamics and its surgical correction in combined arteriosclerotic lesions of the iliac and femoral arteries].

The authors analyse the regional hemodynamics and the results of surgical treatment of 81 patients with coexistent atherosclerotic affections of the iliac and femoral arteries. Radiocontrast angiography and ultrasonic dopplerometry were conducted by elaborated methods for morphofunctional characteristics of arterial circulation. Inclusion of the internal iliac and deep femoral arteries in the main blood flow was the principal method of surgical correction. A differentiated choice of the reconstructive operation allowed a positive result of treatment to be produced in 80.25% of patients in the immediate and in 76.31% of patients in the late-term postoperative periods.
