Controlled balloon false lumen obliteration for the endovascular management of chronic dissection in the descending thoracic aorta

JTCVS Techniques, 2023 · DOI: https://doi.org/10.1016/j.xjtc.2023.01.010 · Published: January 23, 2023

Simple Explanation

This study explores a technique called controlled balloon septal rupture during thoracic endovascular aortic repair (TEVAR) to treat chronic aortic dissection. The goal is to create a single lumen in the aorta by rupturing the dissection septum, preventing blood flow into the false lumen, which can lead to complications. The study reviewed the outcomes of 40 patients who underwent this procedure between 2017 and 2022, assessing clinical and radiographic results.

Study Duration

6 years (2017-2022)

Participants

40 patients undergoing TEVAR with controlled balloon septal rupture technique

Evidence Level

Not specified

Key Findings

1
The study found a midterm aortic-related mortality of 2.5% in a high-risk patient group, with low neurological complications.
2
Complete false lumen thrombosis was achieved in 74% of patients, and favorable aortic remodeling occurred in 97% of patients.
3
There was a 41% rate of early endoleaks, but most were treated medically and did not lead to aortic expansion.

Research Summary

This study evaluates the effectiveness of controlled balloon septal rupture during TEVAR for chronic aortic dissection in the distal thoracic aorta. The technique aims to prevent retrograde false lumen perfusion by creating a single aortic lumen. The study demonstrates promising perioperative and midterm outcomes, including high rates of false lumen thrombosis and favorable aortic remodeling.

Practical Implications

Improved Outcomes in Aortic Dissection

Controlled balloon septal rupture offers a potentially effective endovascular method to manage aortic dissection and improve outcomes compared to traditional TEVAR alone.

Considerations for Patient Selection

Success depends on appropriate patient anatomy, including a distal segment with a suitable diameter for complete wall apposition and false lumen closure.

Risk Management

Careful attention to distal landing zone sizing (1:1) and stent graft taper is crucial to minimize the risk of aortic injury and complications.
