Summary
Kinking of the internal carotid artery (ICA) can cause cerebrovascular symptoms, especially in adults with transient ischemic attacks (TIAs). Surgical correction may benefit adults with symptomatic ICA kinking, particularly when head rotation aggravates symptoms.
Area of Science:
- Vascular Surgery
- Neurology
- Cerebrovascular Disease
Background:
- Kinking and coiling of the internal carotid artery (ICA) are anatomical variations that may be associated with cerebrovascular symptoms.
- While definitive evidence is lacking, these conditions warrant consideration in patients presenting with cerebrovascular disease.
- Kinking is often linked to atherosclerosis, whereas coiling is typically of embryological origin.
Purpose of the Study:
- To evaluate the association between internal carotid artery kinking and symptomatic cerebrovascular disease.
- To assess the potential benefits of surgical correction for patients with symptomatic ICA kinking.
Main Methods:
- Review of clinical evidence and angiographic findings in patients with ICA kinking and coiling.
- Analysis of patient outcomes following surgical intervention for symptomatic ICA kinking.
Main Results:
- Kinking of the ICA, particularly when exacerbated by head rotation, can obstruct blood flow and lead to transient ischemic attacks (TIAs) in adults.
- Surgical correction appears most beneficial for adults experiencing recurrent TIAs associated with ICA kinking.
- Coiling of the ICA is generally asymptomatic and recommendations for surgical intervention in infants are not established.
Conclusions:
- Symptomatic internal carotid artery kinking, especially in adults with TIAs aggravated by head movement, is a strong indication for surgical consideration.
- Distinguishing between atherosclerotic kinking and embryological coiling is crucial for appropriate patient management.
- Further research may clarify the role of surgical intervention for ICA kinking and coiling in specific patient populations.
