Endovascular mechanical thrombectomy in basilar artery occlusion: initial experience

Area of Science:

• Neurology
• Interventional Cardiology
• Vascular Surgery

Background:

• Basilar artery (BA) occlusion is a severe condition often leading to poor neurological outcomes.
• Endovascular mechanical thrombectomy (EMT) offers a potential treatment strategy for acute ischemic stroke due to BA occlusion.

Purpose of the Study:

• To evaluate the efficacy and safety of EMT for patients with basilar artery occlusion.
• To assess outcomes including recanalization rates, neurological improvement, and complications.

Main Methods:

• Retrospective analysis of 16 patients with BA occlusion treated with EMT.
• Utilized direct suction (Penumbra system) and stent retrieval (Solitaire stent) to restore BA flow.
• Outcomes assessed by angiographic recanalization (TICI II-III), NIHSS score improvement, mRS, and hemorrhagic complications.

Main Results:

• Successful recanalization achieved in 75% (Group A, <6h) and 87.5% (Group B, >6h) of patients.
• Favorable outcomes (mRS) observed in 50% (Group A) and 62.5% (Group B).
• Mean age 67.8 years, mean NIHSS 12.3 at baseline.

Conclusions:

• EMT is an effective and safe treatment for basilar artery occlusion.
• The procedure demonstrates positive outcomes even when initiated more than six hours after symptom onset.
