Insights
Restenosis after carotid endarterectomy can occur, leading to significant internal carotid artery stenosis and kinking. This case highlights a successful surgical approach using PTFE graft interposition for complex cases.
Area of Science:
- Vascular Surgery
- Cerebrovascular Disease
- Interventional Cardiology
Background:
- Restenosis after carotid endarterectomy (CEA) affects 6-36% of patients, with intimal hyperplasia and atherosclerosis as key etiological factors.
- Critical carotid stenosis necessitates treatment, with surgical endarterectomy being the primary choice and endovascular therapy considered for restenosis.
- The optimal treatment for concomitant carotid stenosis and kinking post-CEA remains debated.
Observation:
- A 67-year-old male presented with stroke symptoms 8 years after right CEA.
- Doppler ultrasound and angiography revealed 75% internal carotid artery stenosis and kinking distal to the prior endarterectomy site.
- The patient's condition presented a complex challenge due to the combination of stenosis and kinking.
Findings:
- A surgical approach was employed to address the significant stenosis and kinking.
- A 6-mm polytetrafluoroethylene (PTFE) graft was used for interposition between the common and internal carotid arteries.
- The kinking segment of the internal carotid artery was resected as part of the procedure.
Implications:
- This surgical technique offers a viable solution for managing complex restenosis with kinking after CEA.
- Successful surgical intervention can prevent recurrent cerebrovascular events in high-risk patients.
- Further research may clarify the long-term efficacy of this approach compared to other treatment modalities.
Abstract:
According to the literature data, the prevalence of restenosis after carotid endarterectomy ranges between 6 and 36%. The etiological factor is intimal hyperplasia for early period, whereas it is atherosclerosis for late period. A 67-year-old male patient admitted to our clinic with a history of headache and minor stroke. His medical history was significant for right carotid endarterectomy 8 years ago. Recent Doppler ultrasound and digital substraction angiography revealed 75% stenosis and kinking corresponding to the segment distal to the endarterectomy region. Surgical endarterectomy is the treatment of choice in critical carotid stenosis. Endovascular therapy is primarily considered for patients if there is restenosis after carotid endarterectomy. However, the treatment modality is controversial in cases with concomitant carotid stenosis and kinking of internal carotid artery. We present our surgical approach to a case with significant stenosis and kinking of internal carotid artery. We performed a 6-mm-PTFE graft interposition between common and internal carotid artery and resection of the kinking segment.
