Acute mesenteric ischemia (AMI) is associated with high morbidity and mortality due in part to its diagnostic difficulty and operative challenges. The purpose of this study was to review our experience of surgical management in patients with this condition and to identify variables associated with adverse outcomes following surgical interventions. ⋯ Elderly patients and those with a prolonged duration of symptoms had worse outcomes following surgical intervention for AMI. A high index of suspicion with prompt diagnostic evaluation may reduce time delay prior to surgical intervention, which may lead to improved patient survival. Aggressive surgical intervention should be performed as promptly as possible in patients once the diagnosis of AMI is made.

Endovascular procedures have become an integral part of a vascular surgeon's practice. The exposure of surgeons to ionizing radiation and other safety issues have not been well studied. We investigated the radiation exposure of a team of vascular surgeons in an active endovascular unit and compared yearly dosages absorbed by various body parts among different surgeons. Patients' radiation exposure was also assessed. ⋯ With current radiation protection practice, the radiation absorbed by vascular surgeons with a high endovascular workload did not exceed the safety limits recommended by ICRP. Variations in practice, however, can result in significant discrepancy of radiation absorption between surgeons.

To describe a novel technique for maximal reimplantation of intercostal arteries during thoracoabdominal aortic aneurysm repair. ⋯ Paraplegia is an extremely morbid complication associated with TAAA repair. We describe a technique that allows reimplantation of almost all intercostal arteries as one patch circumventing the need for selective reimplantation. Furthermore, our technique ensures continued patency of this patch graft as the outflow resistance is decreased by creating a continuous flow loop. Although this is a small case series, we had no incidence of acute or delayed paraplegia in this high risk group. Our technique of intercostal reimplantation is applicable to all open TAAA repair at high-risk for paraplegia and may be an important adjunct in preventing spinal cord ischemia.

To evaluate our experience of thoracic endoluminal graft (ELG) repair of various thoracic aortic pathologies using a commercially available device approved by the Food and Drug Administration. Our patient population includes patients eligible for open surgical repair and those with prohibitive surgical risk. ⋯ Endoluminal grafting is a feasible alternative to open surgical repair for thoracic aortic pathologies. After more than 300 cases, 30-day morbidity and mortality compares favorably with open repair. Paraplegia remains low as a complication and increases in incidence with retroperitoneal approach, increased perioperative blood loss, and increased aortic coverage.
