Biography

Dr. Clifford Weiss is an assistant professor of radiology and radiological science. He also holds appointments in surgery and biomedical engineering. Additionally, he serves as medical director of the Johns Hopkins Center for Bioengineering Innovation and Design.

Dr. Weiss’ clinical focus lies in vascular and interventional radiology. He specializes in the diagnosis and treatment of vascular malformations, including pulmonary arteriovenous malformations and hereditary hemorrhagic telangiectasia; varicoceles; MRI-guided interventions, especially for the treatment of vascular malformations; advanced venous interventions; and advanced biliary interventions.

Dr. Weiss received his M.D. from the Johns Hopkins University School of Medicine in 2001. He completed an internship in internal medicine in 2002, his residency in radiology in 2007, and a fellowship in vascular and interventional radiology in 2008, all at The Johns Hopkins Hospital.

He is certified by the American Board of Radiology in diagnostic radiology and in vascular and interventional radiology, and he is a member of the Society of Interventional Radiology.

    Clinical Trials

    BEAT Obesity Trial 

    The purpose of this study is evaluate the safety and effectiveness of bariatric embolization as a minimally-invasive image-guided procedure for morbid obesity. In this procedure, specific blood vessels to the stomach are blocked in order to suppress some of the body''s signals for feeling hungry, leading to weight loss.

    Morbid obesity is currently treated with diet and exercise, medications, and surgery. This study is designed to help treat obesity using a minimally invasive, non-surgical, angiographic (through the blood vessel) approach. This procedure is similar to a common procedure used to treat bleeding within the stomach. This version of the procedure has been named "bariatric embolization".

    Although there are over 40 hormones that limit food intake, there is only one hormone, ghrelin that has been shown to stimulate (prompt) food intake. In obese patients, eating fails to suppress ghrelin levels, which is believed to prevent feeling full after a meal and to lead to overeating. Due to the strong hunger craving effects of ghrelin, this hormone has been a target for the treatment of obesity and weight loss. More recently, ghrelin has been shown to have a significant role in the long-term effect of weight loss in bariatric (obesity) surgery where ghrelin levels are shown to be much lower when compared to untreated patients.

    Recent data collected in animals in has shown that blocking blood vessels to a particular portion of the stomach (bariatric embolization) can temporarily decrease levels of the appetite inducing hormone ghrelin, and decrease short-term weight gain. In a study of 5 people, there was a decrease in ghrelin levels and weight loss in the first 6 months after the procedure, but there is no information about the effects of the procedure over longer periods of time.

    We hope to learn if bariatric embolization results in safe and effective weight loss in people who are morbidly obese.
