Angiographic catheter: unique tool for neuroendoscopic surgery

Area of Science:

• Neurosurgery
• Medical Devices
• Endoscopic Surgery

Background:

• Neuroendoscopic surgery for intraventricular and juxtaventricular space-occupying lesions (SOL) requires specialized instruments.
• Existing rigid and flexible forceps and scissors have limitations in maneuverability.
• This study explores the use of modified angiographic catheters for SOL removal.

Purpose of the Study:

• To evaluate the efficacy of cut angiographic catheters in neuroendoscopic removal of intraventricular and juxtaventricular space-occupying lesions.
• To present the surgical experience with this novel instrument.

Main Methods:

• Seventy-one patients with intraventricular and juxtaventricular lesions underwent endoscopic procedures using cut angiographic catheters (5F-8F, 30-35 cm).
• Lesions were cystic, solid, or mixed; cystic lesions were aspirated, and solid tumors were biopsied, decompressed, or excised by suction.
• Catheter effectiveness was dependent on lesion consistency.

Main Results:

• Complete excision, near-total removal, and biopsy were achieved in 14, 19, and 38 patients, respectively.
• Soft lesions were effectively removed by suction; firm lesions required biopsy.
• A complication of major bleeding occurred in one case (craniopharyngioma) and was managed successfully.

Conclusions:

• Cut angiographic catheters are a simple, effective, and versatile tool for neuroendoscopic surgery.
• This technique facilitates the endoscopic management of diverse intraventricular and juxtaventricular lesions.
