[Value of myocardial revascularisation surgery before correction of sub-renal aortic aneurysms]
Insights
Performing aortocoronary bypass (ACB) before abdominal aortic aneurysm (AAA) repair is beneficial for symptomatic patients. However, its necessity in asymptomatic patients requires further investigation due to complex diagnostics.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Interventional Cardiology
Context:
- Simultaneous surgical correction of infrarenal abdominal aortic aneurysm (AAA) and aortocoronary bypass (ACB) is complex.
- Patient selection for combined procedures requires careful consideration of coronary artery disease (CAD) status.
- Diagnostic challenges include the need for comprehensive coronary and cervical arteriography.
Purpose:
- To evaluate the impact of prior ACB surgery on outcomes for patients undergoing AAA repair.
- To compare hospital mortality and long-term morbidity between different patient groups based on ACB and CAD status.
- To clarify the indications for ACB in patients with AAA.
Summary:
- A study compared outcomes in 6 patients with prior ACB and AAA repair (Group I), 14 with AAA and CAD without prior ACB (Group II), and 16 with AAA and no CAD (Group III).
- Group I had nil hospital mortality and remained asymptomatic post-operatively. Group II experienced 2 deaths from myocardial infarction and 1 developed angina. Group III had 2 deaths (infection, cerebrovascular accident).
- While ACB is indicated for symptomatic CAD patients undergoing AAA repair, its role in asymptomatic patients remains debatable due to diagnostic complexities.
Impact:
- Findings suggest that performing ACB before AAA repair in symptomatic patients reduces perioperative mortality and improves long-term outcomes.
- The study highlights the importance of thorough pre-operative evaluation, including coronary and cervical arteriography, for patients with AAA.
- Results provide evidence to guide clinical decision-making regarding the optimal timing and necessity of ACB in the context of AAA repair.
Abstract:
The value of aortocoronary bypass (ACB) before surgical correction of infrarenal abdominal aortic aneurysm (AAA) was studied in three groups of patients. Group I: 6 patients undergoing both procedures; group II: 14 coronary patients operated for AAA without prior ACB surgery; group III: 16 patients without coronary artery disease operated for AAA. The hospital mortality was nil in group I; 2 patients died of myocardial infarction in group II; 2 patients died of infection and of cerebrovascular accident respectively, in group III. The patients in group I were asymptomatic on follow-up (mean = 29.7 months) whilst 1 patient in group II developed angina. The essential problem associated with this type of patient remains the complexity of the diagnostic investigations which must include coronary and cervical arteriography. Although the indications for ACB before cure of AAA are obvious in symptomatic patients and/or with previous myocardial infarction, they remain debatable in other patients.
