Aneurysm Shape and Sac Shrinkage After Total Arch Replacement With Frozen Elephant Trunk for True Aortic Arch Aneurysm.

ABSTRACT:

Objectives

This study aimed to evaluate midterm outcomes and identify predictors of sac shrinkage following total arch replacement with a frozen elephant trunk (TAR-FET) for true aortic arch aneurysms.

Methods

A retrospective analysis was conducted on 28 patients who underwent elective TAR-FET for true arch aneurysms between July 2014 and March 2022. Postoperative sac changes on CT were categorized as shrinkage (≥5 mm reduction), enlargement (≥5 mm increase), or no change (<5 mm change). The sphericity index, a novel morphological parameter, was calculated by dividing the average axial and sagittal sac diameters by sac length.

Results

The median age was 74 years, and 23 were male. No operative deaths or recurrent laryngeal nerve palsy occurred. Among 28 patients, 12 e
