Extra-anatomic iliac to superior mesenteric artery bypass after bridge endovascular treatment for chronic mesenteric ischemia. A case report

A 60 year old patient presenting chronic mesenteric Ischemia (CMI) was managed with superior mesenteric artery (SMA) stenting as bridge therapy to conventional open surgery. At 5 months follow-up, the SMA stent occluded. During this bridge period the patient gained his general condition and the body mass index (BMI) increased from 18 to 22. The patient was managed subsequently with iliac-SMA bypass in C-loop configuration. At 6 months follow-up the bypass is patent, the patient has no CMI symptoms and his BMI is 25. The endovascular approach did not preclude a subsequent conventional open surgery and it can be safely employed as bridge therapy. An improved patient clinical condition, also during a limited bridge period, can improve the conventional open surgery outcomes.
