[Embolization of the internal iliac artery during endovascular repair of abdominal aortic aneurysms]. / Émbolizatsiia vnutrennei podvzdoshnoi arterii pri éndoprotezirovanii anevrizmy briushnoi aorty.

An abdominal aortic aneurysm is one of frequently encountered cardiovascular diseases, which is often accompanied by an aneurysm of the common and/or internal iliac arteries. Recent trends are towards increased use of endovascular methods of treatment, associated with a certain risk for the development of type IIa endoleaks. This raises the question as to the necessity of embolization of the internal iliac artery while covering it with a stent graft. Our study included a total of 20 patients operated on for abdominal aortic aneurysms combined with aneurysms of the common and/or internal iliac arteries. In order to evaluate the obtained outcomes, the patients were divided into 4 groups depending on the intervention performed. The scope of the performed operations varied from endoprosthetic repair of an abdominal aortic aneurysm with coverage of one internal iliac artery without embolization to endoprosthetic repair of an abdominal aortic aneurysm with coverage of both internal iliac arteries with embolization. In the latter event, two-stage interventions were performed. The duration of follow up amounted to more than 3 years. We assessed the short- and long-term outcomes, with zero lethality and the absence of either specific or non-specific complications observed. Embolization increases the duration of the operation and X-ray exposure, as well as the amount of the contrast medium, thus casting doubt upon the necessity of carrying it out, since the immediate and remote results do not differ as compared with mere coverage of the internal iliac artery.

Endovascular repair of the abdominal aorta is a method of choice in pronounced concomitant pathology and high risk of open surgical treatment. The article deals with a clinical case report of successful surgical management of a patient with an infrarenal aortic aneurysm, transplanted kidney, chronic renal insufficiency, secondary diabetes mellitus, multifocal atherosclerosis with predominant involvement of coronary arteries and lower-limb arteries, in whom open surgical treatment was associated with high risk. Endoprosthetic repair of the abdominal aortic aneurysm was performed with a good postoperative outcome.

[Possibilities of hybrid surgery in treatment of thoracoabdominal aneurysms].

The authors present a clinical case report and review of literature concerning treatment of extremely complicated pathology - thoracoabdominal aortic aneurysm, also reflecting the most difficult problems and complications of classical surgical treatment. A successful clinical example showed advantages of a new, less invasive approach, i.e., hybrid surgery. Based on analysing literature sources, the authors describe controversial points of carrying out a hybrid operation and its results. Accumulating experience in and improving technology of the hybrid operation would make it possible to further improve therapeutic outcomes.

[Endovascular prosthetic repair of abdominal aortic aneurysm combined with crossover femorofemoral bypass grafting].

In pronounced concomitant pathology and high risks of open operative treatment endovascular prosthetic repair of the abdominal aorta is a method of choice. Presented herein is a clinical case report concerning successful surgical treatment of a patient with an aneurysm of the infrarenal portion of the aorta and high risk of open operative treatment. The patient underwent unilateral endovascular prosthetic repair of the abdominal aortic aneurysm and crossover femoro-femoral bypass grafting with a good postoperative outcome.
