[Extra-intracranial artérial by-pass. A clinical experience based upon 40 cases (author's transl)]

Area of Science:

• Neurosurgery
• Vascular Surgery

Context:

• Extra-intracranial bypass surgery has been utilized since 1972 for treating cerebral ischemia.
• Cerebral ischemia poses significant neurological risks, necessitating advanced surgical interventions.

Purpose:

• To evaluate the outcomes and methodology of extra-intracranial bypass procedures in patients with cerebral ischemia.
• To analyze the surgical techniques, patient demographics, and clinical presentations associated with bypass surgery.

Summary:

• Forty patients (34 male, 6 female, aged 28-68) underwent extra-intracranial bypass surgery for transient ischemic attacks (TIAs), prolonged reversible ischemic neurological deficits (PRINDs), or stroke.
• Procedures involved anastomosis between the superficial temporal artery (36 patients) or occipital artery (4 patients) and various branches of the middle cerebral artery.
• Angiography confirmed bypass patency post-operatively and at one-year follow-up.

Impact:

• This study provides insights into the surgical management of cerebral ischemia using bypass techniques.
• Findings contribute to understanding the long-term efficacy and patency rates of extra-intracranial bypasses.
• The data can inform surgical decision-making and patient selection for bypass procedures.
