Thromboembolism in active ulcerative colitis.

Inflammatory bowel disease (IBD) has a range of both intestinal and extraintestinal manifestations. Thromboembolism involving the arterial and/or venous systems is rare. Early recognition and treatment of thrombosis in patients with IBD may prevent progression and minimise complications. However, clear guidelines on the duration of treatment and indications for primary prophylaxis need to be established. We report a case of a young patient with ulcerative colitis, who developed multiple site arterial and venous thrombosis, all occurring within short intervals of each other.
