Aneurysm III: Interprofessional Care

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

Summary

Hybrid aortic arch repair offers a viable option for high-risk patients, with Zone 2 demonstrating better outcomes than Zone 1 regarding endoleaks and mortality. Lifelong surveillance is crucial post-procedure.

Area of Science:

Cardiovascular Surgery
Endovascular Therapy
Aortic Disease Management

Background:

Hybrid aortic arch reconstruction is an alternative for patients unsuitable for open surgery.
This study evaluates outcomes of hemiarch repair in Zone 1 and Zone 2.

Purpose of the Study:

To analyze patient outcomes after hybrid hemiarch repair in Zone 1 and Zone 2.
To compare early and long-term results between the two zones.

Main Methods:

47 patients underwent hemiarch repair between 2004-2012.
Supra-aortic debranching followed by thoracic endovascular aortic repair was performed.
Patients were either refused for open surgery or were emergency cases.

Main Results:

Overall technical success was 81% with 12.8% 30-day mortality.
Zone 2 repair showed a trend towards reduced type Ia endoleaks (4.3% vs 14.9%) and improved follow-up mortality (4.3% vs 10.6%) compared to Zone 1.
Overall survival rate was 70% with a mean follow-up of 50.5 months.

Conclusions:

Hybrid hemiarch repair is feasible in high-risk patients with acceptable perioperative risk and long-term survival.
Zone 2 is an effective option for hybrid arch repair, while Zone 1 carries higher risks of endoleaks and mortality.
Lifelong surveillance is essential after hybrid aortic repair.
