# True Digital Artery Aneurysm: A Case Report

## TL;DR

A rare case of a true aneurysm in a finger artery was successfully treated with surgery, showing good recovery and no complications.

## Contribution

This case report adds to the limited literature on true digital artery aneurysms and highlights effective treatment with ligation and excision.

## Key findings

- A 7-mm true aneurysm in the digital artery was successfully excised with ligation.
- Postoperative recovery was uneventful with no recurrence after one year.
- Sufficient collateral circulation allowed for effective treatment without complications.

## Abstract

True aneurysms of the digital artery are extremely rare, and only several dozen cases have been reported worldwide. A 29-year-old man presented with a pulsatile, tender nodule in his left index finger. Angiography revealed a 7-mm saccular aneurysm of the proper palmar digital artery with well-developed distal collaterals. Under local anesthesia, the aneurysm was excised following proximal and distal ligation. It was histopathologically confirmed as a true aneurysm. Postoperatively, symptoms resolved without ischemic or neurological complications and without recurrence after 1 year. Thus, simple ligation and excision are effective when collateral circulation is sufficient.
