Insights
Surgical treatment for type A aortic dissection shows high mortality, especially in acute cases and older patients (≥70 years). Five-year survival is 70%, with cardiovascular issues being a key cause of late death.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Disease
Context:
- Type A aortic dissection involves the ascending aorta, presenting a significant mortality risk without timely surgical intervention.
- The study retrospectively analyzed 100 patients undergoing surgical repair for type A aortic dissection between 2000 and 2008.
Purpose:
- To evaluate the outcomes and mortality rates associated with surgical treatment of type A aortic dissection.
- To identify patient demographics and disease characteristics influencing surgical outcomes.
Summary:
- Operative mortality was 27% for acute and 20% for chronic dissections.
- Patients aged 70 years or older experienced a 50% mortality rate, compared to 21% in younger patients.
- Bleeding was the most frequent complication (18%), necessitating reoperation. Five-year actuarial survival was 70%.
Impact:
- Surgical intervention for type A aortic dissection carries substantial risk, particularly for elderly patients and those with acute presentations.
- Findings highlight the need for careful patient selection and management strategies to improve survival rates in this high-risk population.
Background:
Tipe A aortic dissection involves the ascending aorta and has high mortality rates without surgical treatment.
Aim:
To report the results of surgical treatment of type A aortic dissection.
Material And Methods:
Retrospective review of medical records of 100 patients aged 17 to 78 years (73% males) operated between January 2000 and August 2008, for type A aortic dissection. Follow up was performed with telephone interviews and review of national death records.
Results:
Eighty three percent of patients had an acute dissection. Operative mortality was 27 and 20% for patients with acute and chronic dissection, respectively. Mortality was 50% among patients aged 70 years or more, compared with 21% among their younger counterparts, The most common complication was bleeding that required a new surgical procedure in 18% of patients. Actuarial survival was 70% at five years. Cardiovascular problems caused the death of two of the nine patients that died during follow up.
Conclusions:
Surgical mortality among patients with type A aortic dissection was higher among patients with acute episodes and those aged 70 years or more.
