Management of Prosthetic Mitral Valve Thrombosis
(2005) Ekim, H.; Akbayrak, H.; Başel, H.; Hazar, A.; Karadaǧ, M.; Kutay, V.; Yakut, C.
Prosthetic mitral valve thrombosis is a lifethreatening complication. Data on complications and outcome are limited. The purpose of this study was to review the clinical experience with the thrombolytic therapy and surgical management of prosthetic mitral valve obstruction in our hospital. Between the January 2001 and April 2005, twelve patients with obstructed prosthetic mitral valve were admitted to our hospital. There were 8 female and 4 male patients ranging in age from14 to 60 years, with a mean age of 34±12 years. In all patients, the diagnosis of prosthetic valve thrombosis was confirmed by echocardiography including transesophageal echocardiography. All patients showed absence or muffering of prosthetic valve sounds. Two of 12 patients received thrombolytic therapy by using streptokinase. In the remaining 10 patients, operations were performed on an emergency basis with median sternotomy and cardiopulmonary bypass techniques using antegrade-retrograde combinated isothermic blood cardioplegia and moderate hypothermia. The principal risk factors of prosthetic valve thrombosis are inadequate anticoagulation or fluctuation in anticoagulation levels. Its treatment is either surgical or with thrombolytics. Although both treatment methods are effective, the latter is gaining favor. However, surgery is often required due to large thrombi and a presence of pannus formation.
Primary Aneurysm of the Greater Saphenous Vein: Case Report and Literature Review
(2010) Ekim, H.; Başel, H.; Odabaşi, D.; Özen, S.
Primary venous aneurysm is a rare vascular abnormality that can occur throughout the venous system. We report a proximal greater saphenous vein aneurysm in a twenty one-year old male. A venous duplex ultrasonographic examination showed a fusiform venous aneurysm (5 cm in diameter) of the proximal greater saphenous vein containing occluding thrombus adherent to its wall and extending to saphenofemoral junction. Operation was performed due to apparent symptoms and the potential risk for thromboembolic complications. Aneurysm was exposed through a vertical left femoral incision. It was totally filled with thrombi. Histopathological examination of the aneurysmal wall demonstrated fibrocellular thickening with irregular vascular proliferation with multiple reduplications of internal elastic lamina. Because of the risk of thromboembolism, saphenous vein aneurysm containing occluding thrombus extending to saphenofemoral junction should be treated surgically.
