[Novel method for lower-half body perfusion at circulatory arrest].
It is generally accepted that patients with thoracic aortic aneurysma (TAA) require surgical reconstruction in the open distal anastomosis method. However, the optimal treatment of those with TAA remains controversial, as some of the postoperative complications are spinal-cord injury, rhabdomyolysis, MNMS and so forth caused by ischemia of lower-half body. Therefore the new Y connector with a one-way valve is useful for open distal anastomosis to avoid ischemia of the lower-half body. Through the branch of the Y connector between the femoral artery cannula and the arterial line, the occlusion balloon catheter is inserted and inflated at the descending aorta for perfusion of lower-half body. This procedure is safer and faster to perform than the conventional methodology in which a puncture is inserted, and a balloon catheter may be used only on the side of blood supply, thus making it possible to minimize the aggression of the patient.
