Surgical treatment of aneurysms of the descending thoracic aorta
Insights
This study shows that simple cross-clamping with Dacron grafts is a safe and effective treatment for descending thoracic aorta aneurysms. The procedure resulted in no deaths or complications in six patients, demonstrating its viability.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Thoracic Surgery
Background:
- Descending thoracic aorta aneurysms pose significant surgical challenges.
- Traditional repair methods may involve complex extracorporeal circulation.
- Developing less invasive techniques is crucial for patient outcomes.
Observation:
- Six patients underwent surgical repair of descending thoracic aorta aneurysms between 1983-1985.
- The technique utilized simple cross-clamping and Dacron tube graft interposition.
- No extracorporeal circulation was employed during the procedures.
Findings:
- The study population had a mean age of 69 years, with three patients presenting with ruptured aneurysms.
- Anesthesia focused on drugs with minimal myocardial depressant effects.
- No postoperative mortality or morbidity was observed in the cohort.
Implications:
- This approach offers a potentially simpler and safer alternative for treating descending thoracic aorta aneurysms.
- Careful pharmacologic blood pressure control is critical for success.
- Further studies with larger cohorts are warranted to confirm these promising findings.
Abstract:
Six patients were operated on for aneurysm of the descending thoracic aorta in 1983-1985 by use of simple cross-clamping and interposition of a Dacron tube graft without extracorporeal circulation. The aneurysm had ruptured in three cases. The patients' mean age was 69 years. Anesthesia and muscle relaxation were obtained by drugs with only minor myocardial depressant action. There was no postoperative mortality or morbidity. Five of the patients have been followed up for at least a year. Careful pharmacologic control of the blood pressure is essential during such surgery. Despite the smallness of the series, it indicates that simple cross-clamping and Dacron graft interposition can be used for treatment of aneurysm of the descending thoracic aorta.
