[Technique and problems of transaxillary angiography of the distal aorta and its branches]
Insights
Transfemoral catheterization is the main method for distal aorta angiography. The transaxillary approach offers a valuable alternative when transfemoral is contraindicated, with manageable risks through careful technique and monitoring.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Diagnostic Imaging
Context:
- Transfemoral catheterization is the standard for distal aorta and branch angiography.
- The transaxillary approach serves as a crucial alternative when transfemoral access is not feasible.
- Patient anatomy, particularly in older individuals, can present challenges to successful aortic arch catheterization.
Purpose:
- To review the transaxillary approach as an alternative to transfemoral catheterization for distal aorta angiography.
- To discuss the risks associated with the transaxillary approach and methods for their mitigation.
- To explore challenges in catheterizing the descending aorta due to anatomical variations and present potential solutions.
Summary:
- The transaxillary approach is a viable alternative for distal aorta angiography when transfemoral catheterization is contraindicated.
- Understanding potential complications and implementing meticulous post-procedure care minimizes risks associated with the transaxillary route.
- Anatomical changes in the aortic arch, common in elderly patients, frequently lead to procedural failures, necessitating a review of existing and novel techniques.
Impact:
- Provides guidance for interventionalists facing challenges with transfemoral access.
- Highlights strategies to improve success rates and patient safety in aortic angiography.
- Contributes to the body of knowledge on alternative vascular access techniques in complex cases.
Abstract:
The primary approach to angiography of the distal aorta and its branches is transfemoral catheterization. Whenever this approach is contraindicated, the transaxillary way is an alternative of full value. The comparatively somewhat higher risk can be reduced to an acceptable minimum by the knowledge of damaging mechanisms and careful postangiographic control. The decrease of the angle between left subclavian artery and aortic arch in older patients renders the approach to the descending aorta more difficult and is the most frequent reason for failures. Since an ideal technique for managing this problem does not yet exist a review of some of the hitherto published suggestions is given, completed by experience of our own.
