This volume contains reports from the 37th Annual Vascular Symposium, which for nearly four decades has been sponsored by the Division of Vascular Surgery at the Feinberg School of Medicine, Northwestern University. The chapters were contributed by 50 experts of national and international standing and were based on their symposium presentations. The full spectrum of vascular surgery is covered: changes in management of extracranial cerebrovascular disease, new treatments for lower extremity arterial occlusive disease, novel techniques for complex venous disease, and cutting-edge developments in aortic stent graft repair in the chest and abdomen. The chapter in this volume, which benefited from the spirited discussions after the corresponding presentations at the symposium, provide in-dept detail and "pearls" from the experts. The text is divided into the following ten sections: Cerebrovascular disease Supra-aortic trunk disease Lower extremity arterial disease Lower extremity venous disease Abdominal aortic disease Visceral and renal artery disease Thoracic aortic disease Thoracoabdominal disease Complex venous problems Upper extremity disease
