ABSTRACT
21-year-old male was admitted for evaluation of a mass shadow on chest film. On chest computed tomography showed 5 cm sized homogeneous low density based on the second thoracic vertebral body in the posterior mediastinum. The patient had been performed thoracic sympathectomy 6 months before admission and oxidized cellulose was used for hemostasis at that operation Surgical resection was performed and microscopic result was foreign body granuloma caused by oxidized cellulose. Oxidized cellulose is an absorbable sterile mesh and used to control capillary or venous bleeding. Although the manufacturer recommends its removal after hemostasis is achieved, in clinical practice it is usually left in situ to reabsorb spontaneously, usually with no untoward effect.

We experienced a case of aneurysm of the sinus of Valsalva dissecting into the ventricular dseptum. This dissection was induced by paravalvular leakage after aortic and mitral valve replacement. This 37-year-old male was admitted via emergency room due to progressive dyspnea. He had undergone aortic valve replacement(carbomedic(R) 23 mm) and mitral valve replacement(carbomedic(R) 31 mm) due to aortic regurgitation and mitral regurgitation about 6 years prior to admission and followed up regularly. The diagnosis was made by transthoracic and transesophageal echocardiography and reconfirmed by root aortography. The inlet of the ventricular septal aneurysmal sac was repaired by one layer suture with 3-0 prolene of the endocardium, epicardium and homograft muscle shoulder altogether. Postoperative course was uneventful and the patient was discharged on the 11th postoperative day.
