Operation experience of atypical ruptured abdominal aortic aneurysm / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate and report surgical management and experience of atypical ruptured abdominal aortic aneurysm (RAAA).</p><p><b>METHODS</b>Clinical data of 52 RAAA patients from May 2002 to February 2015 were retrospectively collected and analyzed. Thirty-three cases were included into this study based on atypical clinical presentation and etiology, including 6 infected RAAA, 5 inflammatory RAAA, 1 traumatic aortic rupture, 6 tuberculotic RAAA, 2 aoritc-vena cava fistula, 3 intestinal fistula and 5 spine erosion cases. Two of them refused operation during preparation, 19 of them received emergency open repair and 13 of them received endovascular aortic repair (EVAR) with 1 case converted to open surgery.</p><p><b>RESULTS</b>The systolic blood pressure of atypical RAAA before operation was (88±16) mmHg (1 mmHg=0.133 kPa), duration time from admission to diagnosis making was (17±10) hours. Perioperative death occurred in 1 patient because of hemorrhagic shock induced acidosis. During follow-up for 3 to 72 months, no operation related complications occured, such as artificial graft infection.</p><p><b>CONCLUSIONS</b>Emergent operation including open surgery and EVAR is crucial for RAAA treatment. Early diagnosis, excellent operative techniques and comprehensive perioperative management are measures conducive to reduce the mortality rate of RAAA.</p>
