Clinical Scorecard: Case Study: Combined Retrograde Transcarotid Stenting for Left Common Carotid Artery Dissection Following Acute Type A Aortic Dissection

At a Glance

Key Highlights

• Endovascular repair is a treatment option for symptomatic carotid artery dissection.
• Transfemoral access may be prohibitive due to altered arch anatomy after graft reconstruction.
• Hybrid approach using retrograde transcarotid access can be effective in complex cases.
• Complete reperfusion achieved with modified Thrombolysis in Cerebral Infarction grade 3.
• Favorable neurological recovery and sustained stent patency at follow-up.
• Monitor for access-site complications post-procedure.

Guideline-Based Recommendations

Diagnosis

• Use computed tomography angiography (CTA) to assess carotid artery status post-surgery.

Management

• Consider hybrid open-endovascular approach for carotid artery dissection when transfemoral access is not feasible.

Monitoring & Follow-up

• Monitor neurological status and perform follow-up imaging to assess stent patency, including CTA and Doppler ultrasound.

Risks

• Access-site complications and embolic risk associated with transcarotid access.

Patient & Prescribing Data

Emergent surgical cervical exposure allows for controlled retrograde access and stent deployment, potentially improving outcomes in complex cases.

Clinical Best Practices

• Utilize direct cervical exposure for retrograde access in cases of complex vascular anatomy.
• Deploy overlapping stents to ensure complete coverage of dissected segments.
• Select patients carefully for the hybrid approach based on anatomical considerations.
