Insights
Endovascular repair using branched and fenestrated endografts offers a viable alternative for chronic aortic dissection when open surgery is not feasible. Careful patient selection and advanced imaging are crucial for successful treatment.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Medical Imaging
Background:
- Chronic aortic dissection presents significant challenges for vascular surgeons, often requiring close imaging surveillance.
- Dilation of untreated aortic segments and extension to supra-aortic and visceral arteries are common.
- Patient comorbidities may limit options for extensive open surgical repair.
Purpose of the Study:
- To evaluate the role of advanced endovascular techniques in managing complex chronic aortic dissections.
- To highlight the importance of detailed anatomical assessment and imaging in patient selection for endovascular repair.
Main Methods:
- Review of clinical data from high-volume aortic centers focusing on thoracic branched and fenestrated endografts.
- Mandatory anatomical study using 3D workstations and high-quality preoperative computed tomography angiography (CTA).
- Emphasis on assessing true lumen working space, arch/visceral artery extension, and false lumen perfusion.
Main Results:
- Thoracic branched and fenestrated endografts are emerging as a valid alternative to open surgery for complex aortic dissections.
- Clinical data are limited, with only a few small series available.
- Successful endovascular exclusion requires meticulous anatomical evaluation and intraoperative imaging support.
Conclusions:
- Endovascular repair with branched and fenestrated endografts is a promising option for chronic aortic dissection, particularly in high-risk patients.
- Preoperative CTA and 3D workstation analysis are essential for patient selection and planning.
- Intraoperative advanced imaging is critical for achieving technical success in these complex procedures.
Abstract:
The treatment of chronic aortic dissection is a major challenge for the vascular surgeon. Close imaging follow-up after the acute episode frequently identifies dilation of untreated aortic segments. Aortic dissection often extends to both the supra-aortic trunks and to the visceral aorta. The poor medical condition that often characterizes these patients may preclude extensive open surgical repair. Recent advances in endovascular techniques provide a valid alternative to open surgery. These complex lesions can now be managed using thoracic branched and fenestrated endografts. However, clinical data are scarce and only 3 small series from 3 high-volume aortic centers are currently available. Careful anatomical study on 3D workstations is mandatory to select patients that are candidates for complex endovascular exclusion; a specific focus on the available working space within the true lumen, extension to the arch and/or the visceral/renal arteries, and false lumen perfusion of visceral vessels is required. An excellent understanding of those anatomic details demands high-quality preoperative CTA. Intraoperative advanced imaging applications are a major adjunct in the achievement of technical success.
