# Two Cases of Satisfactory False Lumen Thrombosis Achieved via Total Arch Replacement Using the Frozen Elephant Trunk Technique for Chronic Aortic Dissection

## TL;DR

Two patients with chronic aortic dissection were successfully treated with a surgical technique called frozen elephant trunk, leading to improved outcomes.

## Contribution

Demonstrates successful use of TAR with FET in treating chronic aortic dissection with favorable thrombosis outcomes.

## Key findings

- Two patients with chronic aortic dissection underwent TAR with FET.
- Postoperative imaging showed true lumen expansion and favorable false lumen thrombosis at six months.

## Abstract

We report two cases of chronic aortic dissection (CAD) that were successfully treated with total arch replacement (TAR) using frozen elephant trunk (FET). Case 1 was a 64-year-old female with incidentally detected CAD. Surgery was planned due to progressive aortic enlargement. The primary entry was in the distal arch, and TAR with FET was performed. Case 2 was a 53-year-old male with an abnormal chest radiography, later diagnosed as CAD. He also underwent TAR with FET. Both patients were discharged without complications. Postoperative computed tomography at six months showed true lumen expansion and favorable false lumen thrombosis.
