Subtle abdominal aortic injury after blunt chest trauma

Recycling and Reinforcing Intimomedial Flap of the Infrarenal Aorta Using Anterior Longitudinal Ligament in Patients With Acute Trauma With Bowel Injuries

We present a patient with blunt abdominal trauma with severe acute right limb ischemia and clinical signs of diffuse peritonitis. Computed tomography angiography showed circumferential dissection of the infrarenal aorta with occlusion of the right common iliac artery. We opted for simultaneous abdomen exploration and open repair of injured aorta. Critical weakening of the aortic wall with imminent rupture was identified intraoperatively. Aortotomy cranially from bifurcation showed circumferential intimomedial dissection. The fixation of fragile intimomedial flap of aortic dissection was achieved with reinforcement using an anterior longitudinal ligament. The long aortoiliac arteriotomy was repaired using a great saphenous vein patch. Patient had uneventful postoperative course and was discharged after 7 days. In patients with abdominal polytrauma with peritonitis, and no available endovascular tools, open surgery for circumferential aortic dissection is possible and successful. Described reinforcement of the posterior aortic wall to the anterior longitudinal ligament should be added to the armamentarium of aortic injury treatment.

Anesthesia for Open Abdominal Aortic Aneurysm Repair

Abdominal aortic aneurysms (AAAs) are the 13th leading cause of death in the United States 1 and approximately 40,000 patients undergo elective AAA repair each year.2 With the population aging, this number is expected to increase. Although the use of endovascular AAA repair is becoming more common, open repair, first reported by Dubost et al. in 1951 remains the gold standard.2 This chapter will review the etiology, risk factors, diagnosis, pathophysiology, operative technique, perioperative management, and postoperative complications of patients undergoing open AAA repair.
