Glossary Entry: Neurovascular Catheter

Overview

Definition: A catheter specifically designed for use in neurovascular procedures, allowing for precise navigation and delivery of therapeutic agents or devices to the brain and surrounding vasculature.

Detailed Description

Types and Variations

Variations: There are various types of neurovascular catheters, including microcatheters, guiding catheters, and balloon catheters, each tailored for specific applications in neurointerventional procedures.

Indications

Common Uses: Neurovascular catheters are commonly used in the treatment of cerebral aneurysms, arteriovenous malformations, and ischemic strokes, among other neurovascular conditions.

Insertion and Placement

Procedure: Neurovascular catheters are inserted through the femoral artery and navigated through the vascular system using fluoroscopic guidance, reaching the target site in the brain where the therapeutic intervention is needed.

Clinical Considerations

Potential Complications

Risks: Potential complications associated with neurovascular catheterization include vessel perforation, dissection, thrombosis, and embolization, which can lead to serious neurological sequelae if not managed promptly.

Care and Maintenance

Maintenance Requirements: Proper flushing and sterilization of neurovascular catheters are essential to prevent infections and ensure the device’s integrity for safe and effective use in neurointerventional procedures.

Additional Information

Related Devices

Associated Terms: Intracranial stents, detachable coils, and flow diverters are often used in conjunction with neurovascular catheters to provide comprehensive treatment for complex neurovascular pathologies.

Innovations and Advancements

Recent Developments: Advances in neurovascular catheter design, such as improved trackability, flexibility, and visualization capabilities, have enhanced procedural outcomes and patient safety in neurointerventional practice.

Regulatory and Safety Notes

Regulations: Neurovascular catheters must comply with regulatory standards set by regulatory bodies like the FDA to ensure their safety, efficacy, and quality in clinical use.
