The use of fenestrated and branched stent graft technology for paravisceral abdominal aortic aneurysms (PAAA) is on the rise; however, its application is limited in the United States to only a few selected centers. Most PAAAs are currently repaired using an open approach. The objective of this study was to determine which patients are at highest risk with open PAAA repair and might benefit most from endovascular repair using fenestrated or branched stent grafts. ⋯ PAD, COPD, and female sex are major risk factors for postoperative mortality after open PAAA repair. Fenestrated or branched stent graft repair may be a more valuable alternative to open repair for patients with one or more of these characteristics who have suitable access vessels.

The evolution of endovascular surgery has increased the vascular surgeon's exposure to radiation, raising concern for female vascular trainees and staff of childbearing years. We developed surveys for female trainees, established vascular surgeons, and program directors in vascular surgery to determine current practices with respect to pregnancy and radiation exposure guidelines. ⋯ There is compelling interest to establish radiation safety guidelines for the pregnant trainee or vascular surgeon. Consideration should be given at the Society leadership level to develop and support radiation safety guidelines for all vascular surgeons.

The resuscitation of patients with ruptured abdominal aortic aneurysms (RAAAs) has not been well studied, and the potential benefit of autotransfusion (AT) is unknown. The increased use of fresh-frozen plasma (FFP) has been associated with decreased mortality rates in trauma patients and may also improve RAAA survival. We explored the influence of intraoperative AT and FFP resuscitation on mortality rates in massively transfused RAAA patients. ⋯ Greater use of AT but not of FFP was associated with survival in massively transfused RAAA patients. No mortality benefit was seen with increased FFP, but few patients had high FFP transfusion ratios. Further study to identify RAAA patients at risk for massive transfusion should be undertaken and a potentially greater role for AT in RAAA resuscitation investigated.
