[A successful surgical treatment of dissecting thoracoabdominal aortic aneurysm using a heparin coated percutaneous cardiopulmonary support system].
A 52-year-old man with dissecting thoracoabdominal aortic aneurysm (impending rupture) involving the celiac, superior mesenteric and renal arteries underwent graft replacement of the thoracoabdominal aorta with reconstruction of all visceral branches and intercostal arteries (Th11,12) with the aid of femoro-femoral bypass. The bypass was performed using a heparin coated percutaneous cardiopulmonary support system with low doses of heparin, maintaining activated coagulation time at about 300 seconds. During the reconstruction of the major visceral branches, the branches were separately cannulated from inside the aorta, and perfused selectively via partial extracorporeal circulation. The intercostal arteries were reconstructed segmentally to minimize the duration of ischemia. During the repair of the intercostal arteries, Fogarty balloon catheters were inserted into the intercostal arteries to prevent back bleeding and ischemia. The patient had a satisfactory postoperative course.
