Supraceliac Aorta-to-SMA Bypass with Ileocecectomy for Acute-on-Chronic Mesenteric Ischemia Complicated by Bowel Necrosis and Perforation

This case involved a 63-year-old female with a history of chronic tobacco use, hypertension, and hyperlipidemia, who had undergone aortobifemoral bypass several months earlier at an outside institution. Shortly afterward, she developed progressive postprandial abdominal pain, alternating constipation and diarrhea, unintentional weight loss, and food fear. During a prolonged hospital admission, she underwent upper and lower endoscopy and autoimmune evaluation, none of which yielded a definitive diagnosis. She was dependent on total parenteral nutrition due to intolerance of enteral intake.
On transfer to our facility, she was found to have a high-grade occlusion of the superior mesenteric artery (SMA), beginning approximately 3–4 cm distal to the ostium, caused by a bulky, calcified atherosclerotic plaque. The SMA origin was patent but significantly narrowed, correlating with her chronic symptoms. Given her worsening condition, surgical exploration was undertaken and revealed necrotic terminal ileum, a contained perforation, and localized peritonitis. A supraceliac aorta-to-SMA bypass was performed using a cryopreserved superficial femoral artery (SFA) graft routed through a retropancreatic tunnel, followed by ileocecal resection.
This surgical video demonstrates critical aspects of complex mesenteric revascularization. The technical elements of supraceliac aortic exposure, retropancreatic tunnel creation, and management of bowel complications provide valuable insights for surgeons encountering similar challenging scenarios. This case demonstrates the continued importance of open surgical expertise alongside endovascular techniques.

Thoracoabdominal aortic aneurysms (TAAAs) are generally asymptomatic and are discovered incidentally on thoracic or abdominal imaging. When they are identified, management is often expectant, depending on the size of the aneurysm and its rate of growth. Surgery is indicated for larger aneurysms and those that expand rapidly so as to avoid the catastrophic rupture of the aneurysm.
This article presents the case of a 70-year-old female with a TAAA, whom had been followed with serial computed tomographic angiography scans. The decision to operate was made when the aneurysm began revealing growth in diameter. Her anatomy was not conducive to endovascular treatment; therefore, her aneurysm was repaired using a traditional open approach.
Aortopexy for Innominate Artery Compression of the Trachea

Tracheomalacia is a rare congenital condition that results in incompetence of the trachea, the main airway, leading to collapse of the trachea during respiration. Most often this is due to inadequate bone formation in the trachea, and this causes it to be dynamically collapsed, which can result in breathing difficulties for the child. Upper respiratory infections can also be more common. While most cases of tracheomalacia resolve by 18 to 24 months of age, a small percentage either continue or cause such severe breathing or feeding issues that surgical intervention is warranted. In cases where the innominate artery is the cause of compression of the weakened trachea, an aortopexy to elevate the vessel up to the sternum and away from the trachea is performed.
Thoracofemoral Bypass: A Retroperitoneal Approach

Surgical intervention for aortoiliac occlusive disease (AIOD) remains a vital tool in the management of AIOD. AIOD is caused by occlusion of the infrarenal and/or iliac arteries, often secondary to atherosclerosis. This article presents a case of a young, male patient with a history of familial hyperlipidemia and chronic tobacco use who underwent a thoracofemoral bypass (TFB) procedure via a retroperitoneal approach.
He presented with classic symptoms of bilateral leg pain when walking, nocturnal lower extremity pain, and correlated diminished lower extremity pulses. TFB was the preferred approach due to the aggressive, soft plaque burden extending into the suprarenal aorta, which precluded endovascular repair and would have increased risk for standard infrarenal aortofemoral bypass (AFB). This video and case report present a detailed explanation of a retroperitoneal approach to a TFB procedure.
