Intraoperative ruptures of thoracic aortic aneurysms.

Intraoperative rupture of thoracic aortic aneurysm is a severe complication which may have an adverse effect on the outcome of operation. Among all intraoperative aneurysmal ruptures the most difficult and uncontrolled are ruptures of aortic aneurysms in the presence of dissection and of false aortic aneurysm during repeat interventions in this area. At intraoperative aortic rupture the priority task of the surgical team consists in urgent attainment of maximal temporary hemostasis and an adequate replenishment of blood loss. Presented herein are two most demonstrative clinical cases of intraoperative aortic ruptures: of the ascending aorta during cannulation of the right atrium and of false aneurysm of the aortic isthmus, which developed after aortic isthmoplasty by dacron patch for coarctation where the posterolateral wall of aneurysm was visceral pleura of the left lung. The authors provide a detailed description of the treatment policy for the given condition. Review the reported data pertaining to the problem under consideration.
