Catheters allow you to receive an extended course of intravenous medication without frequent needle pricks. They also keep you healthy by bypassing problems, such as difficulty swallowing. As an interventional radiologist, Kenneth Spearman, MD, at Central Coast Vein & Vascular specializes in image-guided procedures to precisely insert temporary or permanent catheters. If you need a catheter placement, call the office in Arroyo Grande, California, or schedule an appointment online.
