Case Reports
[Catamenial pneumothorax due to diaphragmatic endometriosis confirmed by histological examination; report of a case].
We reported a case of catamenial pneumothorax caused by diaphragmatic endometriosis that was histologically confirmed. A 49-year-old female who had recurrent chest pain and cough appearing on the day preceding each menstruation from 5 years ago. These episode suggested catamenial pneumothorax. ⋯ Partial resection of the diaphragm including these lesions were performed. Histological examination showing positive for estrogen receptor and progesterone receptor confirmed the presence of endometrial tissue on the diaphragm. The patient has been well controlled by therapy with gonadotropin releasing hormone, without recurrence of catamenial pneumothorax.

Case Reports
[Aortic and mitral valve replacement for calcified valvular annulus in a dialysis patient; report of a case].
A 77-year-old man on hemodialysis was admitted to our hospital due to heart failure. Echocardiography showed aortic valve stenosis and regurgitation, mitral valve stenosis and regurgitaion, and tricuspid valve regurgitation. Catheter examination revealed severe calcification at aortic valve and mitral valve including their annulus. ⋯ Aortic and mitral valve replacement and tricuspid valve annuloplasty were performed. The postoperative course was uneventful. Operative technique to remove calcification from valvular annulus using CUSA and reconstruct of the defect of the annulus with autologous pericardium is a very useful technique to prevent left ventricular rupture, perivalvular leakage and any other complications.

Thoracoscopic surgery under epidural and local anesthesia for intractable pneumothorax were performed in 26 patients. A total of 29 thoracoscopic operation were performed in 26 patients. ⋯ We could control the air leak of intractable pneumothorax with the covering of polyglycolic acid sheets using aerosolized fibrin glue in 25 patients. In all patients postoperative course was uneventful and there was no operative death.

An 83-year-old woman, who had suffered from idiopathic thrombocytopenic purpura (ITP), was admitted to our hospital because of cardiac heart failure and chest pain. The platelet was 42 x 10(4) in microl. Echocardiography revealed moderate aortic stenosis and regurgitation and left ventricular dysfunction. ⋯ Postoperative echocardiography revealed no perivalvular leakage. Preoperative administration of high-dose immunoglobulin and intraoperative platelet transfusion is very effective to minimize hemorrhagic complication in patients with ITP. We herein report an extremely rare quadricuspid aortic valve complicated with ITP.

Spinal cord ischemia (SCI) is one of the most serious complications in patients who undergo thoracic endovascular aortic repair (TEVAR). The incidence of SCI after TEVAR has been supposed to be lower than the one after traditional open surgical repair. However, not a few cases regarding SCI after TEVAR have been reported recently. Since the detailed mechanism of the SCI is still not fully understood, preventive strategies against SCI including preoperative identification of critical segmental artery (CSA) applying the artery of Adamkiewicz, preservation of the CSA, motor evoked potential (MEP) monitoring, and cerebrospinal fluid (CSF) drainage are routinely performed during TEVAR in our practice.
