Drainage Tube Placement for the Management of Rebleeding After Vascular Embolization in a Patient With Neurofibromatosis Type 1

Abstract

Neurofibromatosis type 1 (NF-1), a hereditary disease caused by a mutation of a gene on chromosome 17q11.2, is associated with manifestations in several organs. Although infrequent, vascular abnormalities are a complication of NF-1, and they are the second most common cause of death in patients with NF-1. Repairing the nutrient artery and achieving hemostasis are difficult once the artery has failed, thereby resulting in poor treatment outcomes. Herein, we report a case of a patient with NF-1 who presented with an enormous cervical hematoma caused by bleeding from a branch of the external carotid artery. Vascular embolization was performed initially; however, rebleeding from the embolized site occurred. Following the removal of the hematoma, drainage tube placement was effective in preventing micro-bleeding. Thus, drainage tube placement may be an effective treatment option in patients with rebleeding.
