Summary
Surgical management of recurrent carotid stenosis (RCS) after carotid endarterectomy (CEA) is safe, though technically demanding. A second recurrence is possible, necessitating serial noninvasive testing for patients undergoing repeat CEA.
Area of Science:
- Vascular Surgery
- Cerebrovascular Disease
- Surgical Outcomes
Background:
- Recurrent carotid stenosis (RCS) after carotid endarterectomy (CEA) presents a significant clinical challenge.
- Understanding the outcomes of surgical management for RCS is crucial for patient care.
Purpose of the Study:
- To report surgical management outcomes for recurrent carotid stenosis (RCS) following prior carotid endarterectomy (CEA).
Main Methods:
- A 20-year review of 1209 CEAs identified 82 operations (6.8%) for RCS.
- Patients underwent repeat CEA with various repair techniques, including patch angioplasty and bypass grafts.
- Angiography was used for pre-operative assessment.
Main Results:
- The average time to RCS presentation was 65 months, with 66% of patients symptomatic.
- Operative stroke rate was 4.8%, with minor complications including cranial nerve deficits (7.3%) and wound hematomas (2.4%).
- Patch repair was performed in 74% of cases, while bypass grafts were used in 24%.
Conclusions:
- Repeat endarterectomy for RCS is technically demanding but can be performed safely.
- Long-term follow-up revealed the potential for a second recurrence.
- Serial noninvasive testing is recommended for monitoring patients post-repeat CEA.
