S2290 Venous and Arterial Thromboembolism: Unusual Harbinger of Ulcerative Colitis in a 64-Year-Old

INTRODUCTION: Arterial and venous thromboembolic events are known extraintestinal manifestations of inflammatory bowel disease (IBD). Since elderly patients with IBD require tailored treatment strategies, establishing the initial diagnosis and assessing the etiology of future symptoms are critical. We present a 64-year-old male who underwent left iliofemoral vein and artery thrombectomy for phlegmasia with subsequent diagnosis of severe active ulcerative colitis. CASE DESCRIPTION/METHODS: A 64-year-old otherwise healthy white male presented with a 3-month history of abdominal pain, hematochezia, 20 lb unintentional weight loss, and left lower extremity pain. He quit smoking one year prior to presentation and denied family history of IBD or colon cancer. Vital signs were stable and physical exam revealed left leg swelling and tenderness, cyanosis of the left great toe, and positive fecal occult blood test. Labs showed mild normocytic anemia and elevated fecal calprotectin. The abdominal CT showed thrombosis of the left femoral vein, right sided subsegmental pulmonary embolus, distal abdominal aorta mural thrombus, and left iliac artery occlusion (Figure 1). Anticoagulation was not initiated given concerns for lower gastrointestinal bleed. An Inferior Vena Cava filter was placed the following day with stenting of the left common and external iliac arteries, and thrombectomy of the left common femoral, superficial femoral, and external iliac veins. A colonoscopy showed severe inflammation from the rectum to the descending colon (Figure 2). Colonic biopsies showed active chronic colitis with cryptitis and crypt abscesses consistent with ulcerative colitis (UC). Patient was started on steroids, discharged on hospital day 5, and readmitted 5 days later for right leg pain. The Doppler ultrasound showed an occlusive acute Deep Vein Thrombosis (DVT) of the right posterior-tibial vein, nonocclusive DVT of the right common femoral, superficial femoral, and popliteal veins, and occlusion of right proximal superficial femoral artery. He was started on heparin drip, switched to apixaban on hospital day 5, and discharged on hospital day 8. DISCUSSION: The risk of venous thromboembolism is quite high in elderly adults with UC. The literature suggests that thrombosis and hypercoagulability are features of IBD involved in the occurrence of thromboembolic events. Therefore, it is imperative to consider IBD as a differential diagnosis in elderly patients presenting with unprovoked thromboembolism and gastrointestinal bleeding.Figure 1.: Mural thrombus of the distal abdominal aorta and high-grade left iliac artery occlusion.Figure 2.: Colitis up to the descending colon.

Acute limb ischemia due to abdominal compartment syndrome

Acute limb ischemia (ALI) is caused by embolisms or progressive atherosclerosis. We report the case of a 68-year-old female who presented with acute total occlusion of left iliac artery due to remarkably massive ascites from pancreatic cancer. To our knowledge, no other case reports of ALI caused by acute compartment syndrome have been published. We treated our case successfully by draining the ascites fluid without any balloon angioplasty or stent implantation. The removal of extrinsic compression may be the best treatment for cases of this type.

Robot Assisted Aorto-femoral Bypass

Laparoscopic vascular surgery has not been widely embraced by vascular surgeons because of the specific technical skills needed in performing vascular anastomosis. Robot assisted vascular surgery has shown the possibility to overcome several limitations of laparoscopic vascular surgery in previous studies. We report two cases of robot assisted aortofemoral bypass grafting for aortoiliac occlusive disease. Two male patients, 65 and 62 years old were admitted complaining of disabling claudication. CT angiography revealed total occlusion of left iliac artery and bilateral superficial femoral arteries in one case and concentric stenosis of lower abdominal aorta, severe occlusion of left common iliac artery in the other case. Laparoscopic aortofemoral bypass grafting was performed with a proximal end-to-side anastomosis constructed with robotic arms using Dacron graft. Femoral anastomosis was performed in the conventional method. The aortic clamping times were 80 and 198 minutes and operating times were 435 and 605 minutes, respectively. The patients were discharged uneventfully on postoperative days 20 and 13. Robot assisted vascular surgery is a technically feasible and safe procedure.

Horseshoe Kidney and Buerger's Disease: An Unusual Indication for Axillofemoral Bypass — A Case Report

Buerger's disease is characterized by multiple peripheral arterial occlusions in young, male smokers. It is rarely considered in the differential diagnosis of iliac artery occlusion. This report describes a patient with clinical, radiologic, and pathologic manifestations of Buerger's disease who underwent an axillofemoral bypass procedure because of left iliac artery occlusion in the presence of horseshoe kidney.
