Insights
Abdominal aortic dissection, a rare condition, was successfully treated in two patients using stent graft placement. This endovascular approach effectively closed the false lumen, leading to uncomplicated recovery.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Diagnostic Imaging
Background:
- Aortic dissection typically affects the thoracic aorta.
- Abdominal aortic dissection is rare, particularly without trauma.
Observation:
- Two cases of infrarenal aortic dissection were diagnosed using ultrasound, CT, and angiography.
- Patients underwent endovascular repair via stent graft placement through femoral arteriotomy.
Findings:
- Stent grafts were positioned to occlude dissection entry and reentry points.
- Successful obliteration of the false lumen was achieved immediately post-deployment.
- Follow-up imaging at 16 and 3 months showed no complications.
Implications:
- Stent graft placement is a viable treatment for infrarenal aortic dissection.
- Endovascular repair offers a minimally invasive option for this rare condition.
- This approach demonstrates potential for long-term success in managing abdominal aortic dissection.
Abstract:
Aortic dissection is primarily localized in the thoracic aorta. Dissection of the abdominal aorta is exceedingly rare, especially in the absence of a blunt abdominal trauma. Two cases of a primarily infrarenal aortic dissection were diagnosed by US, CT and angiography. The patients were treated by stent graft placement. The stent grafts were introduced via a femoral arteriotomy through the introducer sheath and were placed so that they occluded entry and reentry of aortic dissection. The stent graft placement caused total obliteration of a false channel of the dissection immediately after endoprosthesis deployment. The patients were followed-up by CT and angiography at 16 and 3 months after surgery without complication.
