Dr. Peter Gregory has been practicing interventional medicine for over ten years, with a particular focus on venous disease and interventional nephrology. Dr. Gregory has extensive experience in minimally invasive vascular procedures and devotes all of his professional time to performing these procedures. He has a keen interest in the minimally invasive treatment of varicose veins and venous reflux, venous and arterial stenosis, and venous access. Nearly all of these procedures are performed utilizing catheter and wire based therapy through "pinhole" access through the skin.
After graduating with a degree in chemistry from the University of Virginia, Dr. Gregory obtained his medical degree from the Medical College of Virginia, where he received the coveted William Branch Porter award for excellence in Internal medicine. Dr. Gregory trained in internal medicine at Washington University in St. Louis and nephrology at Johns Hopkins University in Baltimore. During his tenure at Johns Hopkins, Dr. Gregory trained under the direction of noted interventional radiologist, Dr. W. Perry Arnold, becoming the first Johns Hopkins interventional nephrologist. Dr. Gregory has also incorporated venous port placement to his practice after training with Dr. Robert Hickman, a pioneer in central venous access therapy. Dr. Gregory is one of the earliest certified members of the American Society of Diagnostic and Interventional Nephrology.
Having obtained this unique experience, Dr. Gregory regularly speaks on the topic of vascular intervention. For the past seven years, Dr. Gregory has been providing interventional vascular procedures to venous, nephrology, and oncology patients in the Puget Sound area. He calls Seattle home and is proud to be raising his family in the beautiful Northwest.
Dr. Gregory is a member of the American College of Phlebology and the American Society of Diagnostic and Interventional Nephrology.
At Sound Vascular & Vein, we are pleased to offer the Venefit® procedure, in addition to other treatment modalities for the comprehensive management of venous disease. Like the laser ablation it is a minimally invasive ambulatory treatment alternative to surgical stripping of the greater or lesser saphenous vein. Under ultrasound guidance a small catheter is inserted, usually through a needle puncture in the skin, into the damaged vein. After local anesthesia has been placed around the vein, the catheter is activated and slowly pulled back through the diseased vein. As the catheter is withdrawn, it delivers radiofrequency energy to the vein wall causing collagen to shrink and the vein to close. Following the procedure, the catheter is removed and a bandage or compression stocking is placed on the treated leg. Like the laser ablation procedure the Venefit® procedure may be combined with a mini-phlebectomy procedure.
Sclerotherapy (injections) can be used to treat small areas of varicose veins and spider veins. The procedure is simple. A tiny needle injects the veins with a medication that irritates the lining of the vein. Over a short time, in response to the irritation, the vein closes and is reabsorbed. The blood from the closed vein is routed to properly working veins, restoring correct circulation. Sclerotherapy relieves symptoms due to varicose and spider veins in most patients. With this procedure, veins can be dealt with at an early stage, helping to prevent further complication and unsightliness.
You may need to have one to several sclerotherapy sessions for any vein region and the number of injections varies per session. Generally, normal activities can be resumed after sclerotherapy. Medically prescribed support hose and/or bandages may need to be worn for one to several weeks to assist in resolution of the veins. The procedure, performed at Sound Vascular & Vein, usually causes only minimal discomfort. Bruising and pigmentation may occur after sclerotherapy. If bruising occurs it usually disappears within 1-2 weeks. Although pigmentation almost always fades, it can last for several months. Scarring and other complications are rare.
There are several endovenous lasers being used in the treatment of varicose veins. At Sound Vascular & Vein we currently have two different laser treatment systems to choose between, allowing us to select the best options for your individual needs. The endovenous laser ablation is a minimally invasive treatment performed in an office setting under local anesthesia. It is an alternative to surgical stripping of the greater saphenous vein and CLOSURE® . Using ultrasound, a small catheter is inserted, usually through a needle puncture in the skin into the damaged vein. The laser fiber is then inserted into the vein. Your doctor will then numb the vein and turn on the laser. Its targeted energy heats and seals the vein shut. This procedure usually takes less than one hour. Frequently the laser ablation procedure is combined with the mini- phlebectomy. Afterwards a compression bandage is applied to the leg and you will be up and walking immediately following the procedure and ready to resume normal activities.
Mini phlebectomy is a method of removing varicose veins on the surface of the legs. It is done in the office under local anesthesia. This procedure involves making tiny punctures or incisions through which the varicose veins are removed. The incisions are so small no stitches are required. Even though the varicose veins may look large when patients are standing, they are very collapsible making it possible to remove them through small incisions. The patient is able to walk immediately following the procedure. After treatment, a compression bandage and/or a compression stocking are worn for up to 2 weeks.
This is a treatment of hidden larger varicose veins and perforated veins (which connect the deep vein system to the superficial system). They are injected with our foamed sclerosing solution under ultrasound guidance for better accuracy and coverage of the veins treated.
We offer treatment of spider veins and varicose veins with an FDA approved sclerosing agent. This is an actual injection of a medication into the affected veins that close the veins and shuts down blood flow, ultimately eliminating the veins treated. Our providers foam the solution to allow better resolution and coverage of the veins treated.
