Successful treatment of extensive splanchnic arterial and port...

Venous and arterial thromboembolism is a significant cause of morbidity and mortality in patients with ulcerative colitis (UC). Arterial thrombosis of the splanchnic region is a rare event with a very high mortality rate. Furthermore, it represents a challenging complication since it tends to be overlooked and misinterpreted as a clinical exacerbation of UC. We present the case of a 62-year-old female with pancolonic UC complicated by an extensive arterial thrombosis involving the aorta, the celiac trunk, the hepatic, gastric and splenic arteries and the superior mesenteric artery. A thrombosis of the splenic vein extending into the proximal portal vein was also present. The patient was successfully treated by a combined interventional-radiological and surgical treatment. We discuss the rationale behind our management of this case and review the literature on splanchnic arterial thrombosis associated with UC.
