Document Summary
Inflammation of a vein associated with the formation of a thrombus. Usually occurs in an extremity, most frequently a leg. Accompanied by cordlike or thready appearance to the vessel. Occurs primarily in the lower legs, thighs, and pelvic area. Characterized by aching or cramping pain in legs. Rest and elevation of the affected extremity. Injection of a chemical irritant into the varicosed vein. An abnormal circulatory condition characterized by decreased return of venous blood from the legs to the trunk of the body. Chronically distended veins that may cause damaged valves and pooling of blood may be due to standing or sitting in one position for a long period of time, pregnancy or obesity. Congenital heart defect characterized by a localized narrowing of the aorta. Results in increased blood pressure in upper extremities and decreased blood pressure in lower extremities. Abnormal opening between the pulmonary artery and the aorta due to failure of fetal ductus arteriosus to close after birth.
