# Rupture of the Ulnar Artery in a Case of Neurofibromatosis Type 1

## TL;DR

This paper reports a rare case of ulnar artery rupture in a patient with Neurofibromatosis Type 1, successfully treated with endovascular intervention.

## Contribution

The novelty lies in the successful endovascular treatment of a rare ulnar artery rupture in an NF1 patient.

## Key findings

- Ulnar artery rupture is a rare but possible complication of Neurofibromatosis Type 1.
- Endovascular treatment via brachial artery puncture is an effective approach for such cases.

## Abstract

Neurofibromatosis type 1 (NF1) is a genetic disorder involving an abnormality on chromosome 17, resulting in the production of the protein neurofibromin. Neurofibromin inhibits cell proliferation, and abnormalities in its encoding gene are hypothesized to trigger signals for proliferation, resulting in various lesions. Vascular fragility is a rare complication of NF1; however, ruptures of various vessels have also been reported. Here, we present a case of ulnar artery rupture treated endovascularly by puncturing the ipsilateral brachial artery, achieving excellent results.
