Current state of endovascular surgery of abdominal aortic aneurysm

The endovascular repair of the abdominal aortic aneurysm allows treating patients with severe comorbid pathology. The traditional open surgery is a difficult intervention for the patient, which retains its significance at the present time, since it is accompanied by better results in the long term. The defining moment when choosing the final treatment method is the patient's life expectancy. For successful of the endovascular repair an abdominal aortic aneurysm, a favorable anatomy of the aneurysm, the selection of a stent graft, the presence of extensive experience of the operating surgeon, as well as sufficient material equipment of the medical institution is necessary. In addition, regular monitoring of postoperative complications is a prerequisite for the endovascular repair of an abdominal aortic aneurysm. The risk of complications increases significantly if the aneurysms are unfavorable or difficult. Endovascular correction is performed from 15 to 25% of patients within 5 years after the initial operation. Up to 5% of patients need open surgical conversion. The pre-existing protocols of postoperative follow-up turned out to be unsafe for the patient due to the regularly received radiation load and the nephrotoxic effect of the contrast agent during computed tomography. Therefore, there was a need to create a more rational approach in the prevention, diagnosis and treatment of complications after EVAR. The article presents the main causes, diagnostic methods and principles of treatment of specific complications arising after endovascular repair of an abdominal aortic aneurysm.
