Insights
This study shows that surgical strategies for acute type A aortic dissection are effective, with low in-hospital mortality and no mid-term dissection-related deaths. Therapeutic approaches for aortic dissection are validated.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Dissection Research
Context:
- Acute type A aortic dissection presents significant mortality risks.
- Therapeutic strategies require evaluation for early and mid-term outcomes.
- A review of 75 patients from 2001-2006 provides insight into treatment efficacy.
Purpose:
- To evaluate the early and mid-term outcomes of therapeutic strategies for acute type A aortic dissection.
- To assess the safety and efficacy of surgical interventions in a specific patient cohort.
- To determine the validity of established treatment protocols in managing complex aortic dissections.
Summary:
- Surgical intervention for acute type A aortic dissection, including entry resection with circulatory arrest and antegrade cerebral perfusion, resulted in low in-hospital mortality (4.8%).
- Emergent surgery was indicated for ascending aortic diameter ≥50 mm or ulcer-like projection (ULP).
- No mid-term dissection-related deaths were observed, and a low rate of cerebral infarction occurred in patients with residual brachiocephalic artery dissection.
Impact:
- The findings validate the therapeutic strategies employed for acute type A aortic dissection at the reporting department.
- This study contributes to the understanding of long-term outcomes for aortic dissection patients.
- The presented data supports the current surgical management protocols for complex aortic dissections.
Abstract:
We herein present the early and mid-term outcomes of therapeutic strategies for acute type A aortic dissection in our department. Subjects were 75 patients who were admitted to our department from January 2001 to October 2006. A total of 33 patients had thrombosed dissection: emergent surgery was indicated for cases in which the maximal ascending aortic diameter was > or =50 mm or when ulcer-like projection (ULP) was observed in the ascending aorta. Only 1 case of rupture-related death was observed, in a patient who had a maximal ascending aortic diameter of 52 mm and refused surgery. Although 8 patients were converted to surgery during the chronic phase, elective surgery was recommended in all cases. Surgery consisted of entry resection using open distal anastomosis under circulatory arrest at a bladder temperature of 25 degrees C, with antegrade cerebral perfusion into the 3 cervical branches of arch aorta based on bilateral axillary artery. In-hospital mortality of the 62 patients who underwent surgery was low (4.8%) and no dissection-related deaths were reported for the midterm outcomes. In addition, a low rate of cerebral infarction was observed among cases who had residual dissection of the brachiocephalic arteries after surgery. These findings demonstrate the validity of the therapeutic strategies in our department.
