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.

Methods of learning may differ between generations and even the level of training or the training paradigm, or both. To optimize education, it is important to optimize training designs, and the perspective of those being trained can aid in this quest. The Association of Program Directors in Vascular Surgery leadership sent a survey to all vascular surgical trainees (integrated [0/5], independent current and new graduates [5 + 2]) addressing various aspects of the educational experience. ⋯ For "an urgent need to know," the integrated trainees are especially turning to online texts rather than traditional textbooks, which suggests an opportunity for a shift in educational focus. Point-of-care is the best time for education and feedback, suggesting a continued need for dedicated faculty. The business side of training is underserved and should be addressed.

Review Case Reports
Shotgun wound and pellet embolism to the intracranial carotid artery.
Missile embolism into the cerebral circulation is a very unusual complication of shotgun wounds to the chest or neck. We report a case of an 11-year-old boy who sustained an air gunshot wound and pellet embolism to the intracranial carotid artery. ⋯ The patient was successfully treated by emergency flow reversal and embolectomy. Because this injury is extremely rare, the literature is reviewed, and several principles are suggested to improve the management.

Controversy persists as to whether all calf vein thrombi should be treated with anticoagulation or observed with duplex surveillance. We performed a systematic review of the literature to assess whether data could support either approach, followed by examination of its natural history by stratifying results according to early clot propagation, pulmonary emboli (PE), recurrence, and postthrombotic syndrome (PTS). ⋯ No study of strong methodology could be found to resolve the controversy of optimal treatment of C-DVT. Given the risks of propagation, PE, and recurrence, the option of doing nothing should be considered unacceptable. In the absence of strong evidence to support anticoagulation over imaging surveillance with selective anticoagulation, either method of managing calf DVT must remain as current acceptable standards.

Case Reports
Covered stent use after subclavian artery and vein injuries in the setting of vascular Ehlers-Danlos.
Vascular Ehlers-Danlos (VED) represents a rare disorder in which a defect in collagen synthesis renders vessels to be extremely fragile. We report the successful repair of a subclavian artery pseudoaneurysm via a hybrid technique employing delivery of a covered stent along with video-assisted thoracoscopic ligation of the internal mammary artery in a patient with VED.
