title: Thoracic aneurysmectomy utilizing direct left ventriculofemoral shunt (TDMAC-heparin) bypass.
abstract: Use of a temporary heparin-coated ventriculofemoral shunt in 2 patients in the successful management of traumatic aneurysms of the descending thoracic aorta is described. Safe and effective bypass protection can be achieved by direct ventriculofemoral diversion when cannulation of the left subclavian artery or ascending aorta is hazardous. The use of a heparinized shunt bypass without systemic anticoagulation considerably simplifies the operation.
