Insights
Managing abdominal aortic aneurysm (AAA) with co-existing coronary artery disease (CAD) involves complex surgical decisions. Endolumenal repair offers a less invasive option for staged or combined approaches in AAA repair.
Area of Science:
- Vascular Surgery
- Cardiovascular Surgery
- Aortic Aneurysm Research
Background:
- Coronary artery disease (CAD) significantly increases mortality and morbidity in patients undergoing abdominal aortic aneurysm (AAA) repair.
- The optimal surgical strategy (staged vs. combined) for patients with both critical AAA and CAD remains debated.
- Standard open AAA repair contributes to high mortality and morbidity in these complex cases.
Observation:
- Four cases of concurrent AAA and CAD were managed over 30 months.
- Techniques for endolumenal AAA repair were developed during this period.
- The study presents case reports on managing this unusual comorbidity.
Findings:
- A staged surgical approach is suggested for non-tender AAA (5.5-8.0 cm).
- A combined surgical approach may be preferable for tender or larger AAA (> 8.0 cm) to prevent rupture.
- Endolumenal AAA repair presents a less invasive alternative for both staged and combined strategies.
Implications:
- Endolumenal AAA repair may reduce invasiveness compared to open surgery.
- Case reports offer insights into managing complex AAA and CAD comorbidities.
- Further research with larger series is needed to establish definitive management guidelines.
Background:
The high prevalence of coronary artery disease (CAD) in patients with abdominal aortic aneurysm (AAA) is responsible for most , 30-day mortality and morbidity in elective repair of AAA. The continuing debate regarding staged or combined surgery for AAA and CAD (coronary artery bypass grafting -CABG) in the small number of patients with critical degrees of both co-morbidities has not had a significant impact on the greater mortality and morbidity when the AAA repair is undertaken using the standard open operation.
Patients:
We report four cases with these combined pathologies which we have managed over the last 30 months during which time we have developed techniques of endolumenal repair of AAA.
Conclusions:
Whilst it is not possible to make firm recommendations regarding management strategy owing mainly to a lack of large series reporting this unusual combination of co-morbidities, the options are debated on the basis of published anecdotal evidence as well as our own case reports. We suggest that if the AAA is non-tender and/or 5.5-8.0 cm, the staged approach is appropriate. If the AAA is tender and/or > 8.0 cm, a combined approach may be a better option in order to avoid the risk of AAA rupture during the interval between the operations. Endolumenal repair of AAA offers a further option for the staged and combined approach, and may be less invasive than the standard open surgery for AAA repair.
