Problem: Approximately 4 million live births occur in the United States each year. Pregnancy causes many physical changes in the mother, including venous distension, increased ability to form blood clots, and hormonal changes. Data suggest that these factors help cause venous insufficiency (when the veins do not adequately return blood from the extremities to the torso). As venous insufficiency progresses, complications follow, the most severe of which include superficial thrombophlebitis and deep venous thrombosis (DVT, or blood clots). Although the fear of DVT has been well publicized, its prevention and prevalence in pregnant women has not been well-studied. The exact cause of venous insufficiency is not known. However, known risk factors include being female and hormonal changes associated with oral contraceptive use, certain hormone replacement medications, and pregnancy. Being pregnant places the mother at additional risk for developing venous insufficiency. Compression stockings are used to manage the condition, but this is by no means standard of care despite their easy use and safety. The medical community's understanding of how compression stockings work is largely theoretical; however, it is believed that the compression works by preventing venous hypertension in the lower legs, thereby preventing venous insufficiency and its associated complications. Research hypothesis: The investigators hypothesize that compression stocking use will be associated with lower incidence of varicose veins and, in those patients who already have varicose veins, lower incidence of complications associated with venous insufficiency. Further, the investigators believe that compression stocking use will be associated with a lower incidence or lessening of symptoms associated with venous insufficiency. Importance: An undetected DVT can be fatal. Even if detected promptly, DVT is associated with long term health problems. Treatment of a DVT requires anticoagulation which can be risky to both mother and fetus. The prevention or reduction of DVT in pregnant women through use of compression stockings would revolutionize their care. Further, this intervention is safe and noninvasive. The investigators propose to conduct a randomized, pilot study comparing pregnant women without and with varicose veins randomized to wear compression stockings to a similar group of participants randomized to no compression stocking use.
The investigators propose that evidence of chronic cerebrospinal venous insufficiency (CCSVI) may be evident in the vasculature of the fundus. The investigators will be examining fundi of multiple sclerosis patients and Ehlers-Danlos patients to see if evidence of CCSVI can be found in these patients having high risk for CCSVI. The investigators will read the fundus photos, compared to age-matched normals in a "blind" fashion.
The study is being done to determine if venous angioplasty is an effective treatment for chronic cerebrospinal venous insufficiency (CCSVI). In this condition, areas of narrowing or blockages are present in the internal jugular or azygos veins (veins which drain blood from the central nervous system) and these blockages may be associated with symptoms classically attributed to MS. Therefore, angioplasty may help to improve the symptoms associated with CCSVI and multiple sclerosis (MS). In this study, the investigators will evaluate the effectiveness of angioplasty in the treatment of CCSVI by comparing two the outcomes of two groups of patients: one group with CCSVI diagnosed on a venogram and treated with angioplasty and one group with CCSVI diagnosed on a venogram but not treated. The patients enrolled in this study, and the neurologist evaluating patients after the procedure, will not know whether or not they were treated with angioplasty.
This is a single center, multispecialty, randomized double blind placebo control feasibility clinical trial. The purpose is to evaluate the safety, feasibility and efficacy of percutaneous transluminal angioplasty in treating extracranial venous obstructive lesions, and its influence on the clinical outcomes of Multiple Sclerosis (MS) patients that have been found to have chronic cerebrospinal venous insufficiency (CCSVI).

The intent of this protocol is to obtain blood samples from subjects with or without a wound, so the blood can be used in wound-related scientific studies. It is also the intent of this protocol to salvage debrided wound material that is normally destined for destruction, so it can be used in wound-related scientific studies.
Severe skin damage caused by chronic venous disorders (CVDs) results in relentless pain and poor quality of life for millions of adults in the U.S. each year. DVDs are under-recognized and under-treated disorders shat harm the veins of the legs and at worst, cause skin inflammation and venous leg ulcers. A new way to ease the pain and inflammation is proposed in this study of cryotherapy (cool gel wraps) applied to damaged skin of the lower legs of CVD-affected individuals. The study hypothesis predicts that this novel cryotherapy model and method will significantly improve the health and quality of life for those with CVDs and that the intervention will become a standard of care for CVDs. In addition, the method will, over time, reduce health care costs associated with treating poor CVD outcomes.
This trial is designed as a prospective, non randomized, single center clinical trial to determine the safety and efficacy of laser ablation of incompetent perforator veins. Within this clinical evaluation, fifty (50) limbs will be treated with Vari-Lase ®. A duplex ultrasound will verify the presence or absence of incompetent perforator veins (IPV). In addition, the number, diameter and location of the IPVs will be determined. Limbs with IPVs which measure greater than or equal to 3mm in diameter and are located superior to the foot and distal ankle will be considered for entry into the study.
