An unusual complication of carotid stenting: spontaneous rectus sheath hematoma and its endovascular management.

Carotid stenting has recently emerged as a potential alternative to surgical treatment. We report a case of a spontaneous rectus sheath hematoma in a patient who underwent anticoagulation therapy following carotid stenting. Computed tomography findings were consistent with active bleeding within the hematoma, and this was confirmed with selective angiography via right deep circumflex iliac artery injection. Transcatheter embolization of the right deep circumflex iliac artery with n-butyl 2-cyanoacrylate was successfully performed. To the best of our knowledge, spontaneous anterior abdominal wall hemorrhaging following carotid stenting has not been previously reported in the English language literature.
