Background— Mycotic aortic aneurysm (MAA) is a rare and life-threatening disease. The aim of this European multicenter collaboration was to study the durability of endovascular aortic repair (EVAR) of MAA, by assessing late infection–related complications and long-term survival. Methods and Results— All EVAR treated MAAs, between 1999 and 2013 at 16 European centers, were retrospectively reviewed. One hundred twenty-three patients with 130 MAAs were identified. Mean age was 69 years (range 39–86), 87 (71%) were men, 58 (47%) had immunodeficiency, and 47 (38%) presented with rupture. Anatomic locations were ascending/arch (n=4), descending (n=34), paravisceral (n=15), infrarenal aorta (n=63), and multiple (n=7). Treatments were thoracic EVAR (n=43), fenestrated/branched EVAR (n=9), and infrarenal EVAR (n=71). Antibiotic was administered for mean 30 weeks. Mean follow-up was 35 months (range 1 week to 149 months). Six patients (5%) were converted to open repair during follow-up. Survival was 91% (95% confidence interval, 86% to 96%), 75% (67% to 83%), 55% (44% to 66%), and 41% (28% to 54%) after 1, 12, 60, and 120 months, respectively. Infection-related death occurred in 23 patients (19%), 9 after discontinuation of antibiotic treatment. A Cox regression analysis demonstrated non-Salmonella–positive culture as predictors for late infection–related death. Conclusions— Endovascular treatment of MAA is feasible and for most patients a durable treatment option. Late infections do occur, are often lethal, and warrant long-term antibiotic treatment and follow-up. Patients with non-Salmonella–positive blood cultures were more likely to die from late infection. # CLINICAL PERSPECTIVE {#article-title-32}Background— Mycotic aortic aneurysm (MAA) is a rare and life-threatening disease.

Purpose To describe our experience with a novel technique to decompress abdominal compartment syndrome after endovascular aneurysm repair (EVAR) of ruptured abdominal aortic aneurysm (rAAA). Method From January 2003 to April 2010, 13 patients (12 men; mean age 75 years) treated for rAAA with EVAR underwent tissue plasminogen activator (tPA)–assisted decompression for intra-abdominal hypertension. All of the patients but one had intra-abdominal pressure >20 mmHg, with signs of multiple organ failure or abdominal perfusion pressure <60 mmHg. With computed tomography guidance, a drain was inserted into the retroperitoneal hematoma, and tPA solution was injected to facilitate evacuation of the coagulated hematoma and decrease the abdominal pressure. Results In the 13 patients, the mean intra-abdominal pressure decreased from 23.5 mmHg (range 12–35) to 16 mmHg (range 10–28.5). A mean 1520 mL (range 170–2900) of blood was evacuated. Urine production (mean 130 mL/h, range 50–270) increased in 7 patients at 24 hours after tPA-assisted decompression; among the 5 patients in which urine output did not increase, 3 underwent hemodialysis by the 30-day follow-up. One patient did not respond with clinical improvement and required laparotomy. The 30-day, 90-day, and 1-year mortality was 38% (5/13 patients); none of the deaths was related to the decompression technique. Conclusion tPA-assisted decompression of abdominal compartment syndrome after EVAR can decrease the intra-abdominal pressure and could be useful in preventing multiple organ failure. It is a minimally invasive technique that can be used in selected cases but does not replace laparotomy or retroperitoneal surgical procedures as the gold standard treatments.

Innominate artery (IA) traumatic injuries are rare but life-threatening, with high mortality and morbidity. Open surgical repair is the treatment of choice but is technically demanding. We describe a case of blunt trauma to the IA with ongoing bleeding, treated successfully by combined (hybrid) endovascular and open surgery. The case demonstrates the immediate usage of modern endovascular and surgical tools as part of endovascular and hybrid trauma management.

The usage of resuscitative endovascular balloon occlusion of the aorta, also known as aortic balloon occlusion, is an emerging method for bleeding control as a bridge to definitive treatment in trauma management. We describe a trauma case where resuscitative endovascular balloon occlusion of the aorta was used as part of the EndoVascular hybrid Trauma and bleeding Management concept to facilitate transient hemorrhage control and thereby to permit damage control surgery. The case is an illustration of the adoption of a multidisciplinary approach.
