Glossary Entry: Vascular Sheath

Overview

Definition: A tubular device used to facilitate the insertion and placement of various cardiovascular devices, such as catheters or guidewires, into blood vessels during diagnostic or interventional procedures.

Detailed Description

Types and Variations

Variations: Vascular sheaths come in various sizes and lengths to accommodate different procedures and patient anatomy. They may be hydrophilic-coated for smoother insertion or have hemostatic valves to prevent bleeding.

Indications

Common Uses: Vascular sheaths are commonly used in procedures like cardiac catheterization, angiography, angioplasty, and stenting to provide access to the vascular system.

Insertion and Placement

Procedure: The vascular sheath is typically inserted into a blood vessel over a guidewire using the Seldinger technique. Once in place, it provides a conduit for the introduction of other devices or delivery of medications.

Clinical Considerations

Potential Complications

Risks: Potential complications of using a vascular sheath include bleeding, hematoma formation, infection, vascular injury, and pseudoaneurysm formation.

Care and Maintenance

Maintenance Requirements: After use, the vascular sheath should be removed carefully to avoid complications. Proper hemostasis and monitoring for bleeding are essential post-procedure.

Additional Information

Related Devices

Associated Terms: Hemostatic valves, introducer sets, guidewires, catheters, angioplasty balloons, and stents are often used in conjunction with vascular sheaths.

Innovations and Advancements

Recent Developments: Advances in vascular sheath technology include the use of hydrophilic coatings, hemostatic valves, and radial access sheaths to improve safety and patient outcomes.

Regulatory and Safety Notes

Regulations: Vascular sheaths are medical devices regulated by health authorities to ensure their safety and efficacy in clinical use. Healthcare providers should be trained in their proper use and handling to minimize risks to patients.
