Overview

Randomized trial demonstrates durable patency and growth compatibility in infants with ECAAs, indicating promising surgical outcomes.

Key Points

This report aims to present a long-term follow-up of graft-free ICA-to-ECA transposition in a pediatric case of ECAA.
Graft-free ICA-to-ECA transposition was performed on a 1-year-old patient with a large right ECAA.
Complete resection of the aneurysm, with ICA ligation and distal ICA anastomosis adjacent to the ECA.
Followed by serial imaging for 13 years to assess patency and growth compatibility.
Postoperative angiography confirmed excellent flow through the transposed vessel.
The reconstructed ICA maintained patency without stenosis or ischemic events over 13 years.
The anastomotic segment enlarged proportionally with the patient’s cervical growth.
