Key result
Transcatheter occlusion of bleeding arteries successfully treated life-threatening rectal hemorrhage in a long-term methamphetamine user with severe arterial stenotic lesions.
Why the study?
Massive hematochezia as a complication of methamphetamine-induced vasculitis and its treatment by transcatheter hemostasis is not well characterized.
Case Report (n=1)
Transcatheter occlusion can be an effective treatment for massive hematochezia caused by methamphetamine-induced vasculitis.
A long-term, heavy methamphetamine user with life-threatening rectal hemorrhage was treated with transcatheter occlusion of the bleeding arteries. The bleeding blood vessels were vulnerable submucosal arteries, part of the collateral supply to the distal colon. Visceral arteriography demonstrates severe arterial stenotic lesions of the celiac axis, superior mesenteric artery and the inferior mesenteric artery. Collateral vessels were seen with corkscrew morphology similar to that seen with thromboangiitis obliterans.

Link et al. (2011) conducted a case report in Massive hematochezia secondary to methamphetamine-induced vasculitis (n=1). Transcatheter occlusion of bleeding arteries was evaluated on Hemostasis. Transcatheter occlusion of bleeding arteries successfully treated life-threatening rectal hemorrhage in a long-term methamphetamine user with severe arterial stenotic lesions.
