A 17-year-old girl with Klippel-weber syndrome complicated with a pulmonary thromboembolism and RV thrombus

Abstract

A 17-year-old girl with multiple areas of skin hemangiomas that had been present since birth was referred to our institution complaining of sudden onset of dyspnea. Enhanced CT demonstrated a pulmonary thromboembolism and transthoracic echocardiogram showed a thrombus-like echo in the right ventricle. CT further revealed thrombi in the inferior vena cava (IVC) and peripheral vein. The thrombi, especially those in the RV, were highly life-threatening; therefore, immediate thrombectomy was performed and an IVC filter was placed. Because no major complications occurred, the patient was discharged 34 days after admission. In such young women, carefully using anticoagulation therapy and planning pregnancy are recommended. © 2013 The Japanese Society of Internal Medicine.
