Insights
Abdominal aortic aneurysms (AAA) are increasingly diagnosed in elderly patients with complex vascular conditions. This review details managing cardiac high-risk patients with AAA, focusing on treatment options and preoperative assessments.
Area of Science:
- Vascular Surgery
- Cardiology
- Geriatric Medicine
Background:
- Increasing incidence of abdominal aortic aneurysms (AAA) due to aging population and improved diagnostics.
- AAA frequently coexists with generalized atherosclerosis, leading to significant cardiac and peripheral arterial comorbidities.
- Elderly AAA patients often present as high-risk surgical candidates due to coronary artery disease and left ventricular dysfunction.
Purpose of the Study:
- To review optimal management strategies for cardiac high-risk patients with AAA.
- To discuss the considerations for medical treatment, coronary revascularization, and treatment in the elderly population.
- To provide guidance on the timing and modality of treatment for this complex patient group.
Main Methods:
- Review of current literature on AAA management in high-risk cardiac patients.
- Analysis of treatment strategies including medical management, endovascular repair, and open surgery.
- Discussion of preoperative cardiac evaluation and intervention.
Main Results:
- High prevalence of coronary artery disease and peripheral arterial occlusive disease in AAA patients.
- Endovascular approaches may be limited by severe peripheral arterial disease.
- Careful patient selection and risk stratification are crucial for successful outcomes.
Conclusions:
- Optimal management requires a multidisciplinary approach, balancing AAA treatment with cardiac risk.
- Preoperative coronary revascularization decisions must be individualized.
- Age and comorbidities significantly influence treatment choices for AAA patients.
Abstract:
With increasing age of the general population, a higher awareness of the disease, better screening methods and the option of less invasive therapeutical strategies, the incidence of abdominal aortic aneurysms (AAA) is rising steadily. Since AAA is a disease of the elderly patient with generalized atherosclerosis, there is a high coincidence with other vascular morbidities. Especially the presence of coronary artery disease and concomitant left ventricular dysfunction proves many of those patients to be cardiac high risk patients with respect to an operative approach. On the other hand, a high coincidence of severe peripheral arterial occlusive disease might hamper the endovascular approach and endovascular therapy might carry a high risk for these patients as well. Therefore, it is of utmost importance to consider how and when cardiac high risk patients with AAA should be treated. In this review therefore special aspects such as the choice of medical treatment, the need of preoperative coronary revascularization and the situation in old patients are discussed in detail.
