Insights
A patient with carotid artery stenosis and an intraluminal thrombus underwent successful carotid artery stenting (CAS). Immediate diagnosis and careful management are crucial due to the high risk of embolism.
Area of Science:
- Neurology
- Vascular Surgery
- Interventional Cardiology
Background:
- Significant carotid artery stenosis poses a risk for transient ischemic attacks and stroke.
- Intraluminal thrombus formation in stenotic carotid arteries presents unique challenges during intervention.
Observation:
- A 77-year-old male experienced transient left-hand motor weakness, indicative of a potential cerebrovascular event.
- Cerebral angiography revealed severe (90%) stenosis at the right internal carotid artery origin.
- A large intraluminal thrombus was identified during planned carotid artery stenting (CAS).
Findings:
- The intraluminal thrombus was successfully aspirated using an aspiration catheter.
- Distal protection with a filter wire device was employed during the procedure.
- Carotid artery stenting was completed without any procedural complications.
Implications:
- Carotid stenosis with intraluminal thrombus requires immediate and thorough diagnosis before stenting.
- The presence of thrombus increases the risk of distal embolization during CAS.
- Prompt identification and management of thrombus are essential for safe and effective CAS procedures.
Abstract:
A 77-year-old man presented with transient motor weakness of the left hand. Cerebral angiography showed 90% stenosis at the origin of the right internal carotid artery. Carotid artery stenting (CAS) was performed 3 weeks later, and a large intraluminal thrombus was found during the procedure. The blood around the thrombus was aspirated using an aspiration catheter under distal protection with a filter wire protection device, and CAS was successfully performed without complications. Although this patient was treated by CAS without complications, carotid stenosis associated with intraluminal thrombus-because it has a high risk of distal embolism-should be carefully diagnosed immediately before CAS.
