Comparative StudyRisk models for mortality following elective open and endovascular abdominal aortic aneurysm repair: a single institution experience.
To develop and validate an "in house" risk model for predicting perioperative mortality following elective AAA repair and to compare this with other models. ⋯ In this study, an "in-house" developed and validated risk model has the most accurate discriminative value in predicting perioperative mortality after elective AAA repair. For purposes of comparative audit with case mix adjustments, national models such as the VGNW or Medicare models should be used.

ReviewProphylactic perioperative anti-thrombotics in open and endovascular abdominal aortic aneurysm (AAA) surgery: a systematic review.
Heparin is used worldwide by vascular surgeons as prophylaxis for arterial thrombo-embolic complications during open and endovascular arterial surgery. Possible harmful effect of heparin use is more perioperative blood loss, resulting in a higher morbidity and mortality. To evaluate the evidence for the use of heparin during aorto-iliac arterial surgery a review was performed. ⋯ Despite limitations this review showed no compelling evidence on the beneficiary effect of the prophylactic perioperative use of heparin during open surgery for (r)AAA. Authors will promote a randomised controlled multi-center trial on this topic for elective open surgical repair of AAA.

Comparative StudyFactors related to postoperative delirium in patients with lower limb ischaemia: a prospective cohort study.
To preoperatively determine candidates at definitive risk of postoperative delirium (POD), we identified relevant factors in patients with arteriosclerosis obliterans who underwent bypass surgery. ⋯ This study identified 5 risk factors for POD in patients undergoing bypasses for limb ischaemia. Long-term outcomes were similar when comparing the patients who experienced POD with those who did not.
