Endovascular Repair for Abdominal Aortic Aneurysm Rupture With Neurofibromatosis Type 1

Massive Hemorrhage Following Acupuncture Treatment in a Neurofibromatosis Type 1 Patient

Neurofibromatosis type 1 (NF1) is a genetic disorder involving multiple organs. Vascular involvement is a rare complication among NF1 patients. We report a case of a 59-year-old female NF1 patient who presented with a massive hematoma over the scapular area after undergoing acupuncture treatment. Contrast-enhanced CT and MRI demonstrated a slightly hyperdense mass measuring 24.2 × 10.3 cm in size, and multiple enlarged and tortuous malformed vessels were seen arising from the left subclavian artery. Arterial embolization and subsequent surgical mass resection were successfully performed. This case indicates that minor injuries such as acupuncture-related ones could cause severe hemorrhage in patients with vascular malformation related to NF1. Endovascular angiography and embolization proved to be effective in localizing the culprit vessel and stopping active bleeding in our patient.

Endovascular treatment for a ruptured lumbar artery aneurysm in a patient with neurofibromatosis type 1

The present medical case report describes successful endovascular treatment via stent graft and coil packing for a ruptured lumbar artery aneurysm in a 55-year-old woman with neurofibromatosis type 1. Although less common, vasculopathy, such as an aneurysm, stenosis, rupture, and arteriovenous fistula, have been reported and can be a cause of death for patients with this disorder. However, only a few cases of a ruptured lumbar aneurysm have been reported.
