title: [Current treatment of acute type A aortic dissection. Surgical treatment and treatment of malperfusion syndrome].
abstract: Acute type A aortic dissection is a surgical emergency. Treatment is based on dissected ascending aortic replacement and correction of an associated aortic insufficiency. Catheterization of the axillary artery, open distal anastomosis and systematic resection of the intimal tear are the main surgical evolutions of the last years. They allowed to significantly reduce intraoperative mortality rate particularly due to bleeding. Thirty days mortality rate of operated aortic dissection is about 20 to 30%. Visceral malperfusion syndromes induced by aortic dissection represent an important cause of postoperative death. An early diagnosis and treatment appears necessary. Thoracoabdominal CT scan allows understanding mechanisms inducing malperfusion. Aortography and an emergency endovascular procedure allow restoring arterial blood flow before renal or mesenteric irreversible ischemia. Collaboration between radiologist, anesthesiologist and surgeon is necessary to optimize survival of acute type A aortic dissection.
