We gave Borei-takusya-san to six patients with intractable edema under the waist. This treatment cured three of the six. Two of the cured patients had Ki-deficiency or Yang-Ki-deficiency in the kidneys. In these cases, we first intensified Ki in the kidneys and improved their conditions to Yin-disease, first stage. We noticed improvement of their subjective symptoms and objective signs after we gave them Borei-takusya-san in combination with their prescriptions. All of the ineffective cases presented some conditions of hypo-tonus or hypo-reactivity.
With reference to many ancient medical books and our own experience we studied the use of Borei-takusyasan. It applies to patients (1) with oliguria, (2) with edema under the waist, (3) without Ki deficiency and Yang-Ki-deficiency in the kidneys and with (4) more reactive stage than Yang-disease, second stage and Ki between excess and deficiency. (5) If they had Ki-deficiency or Yang-Ki-deficiency in the kidneys, we should first replenish with Ki sufficiently, and make out prescriptions for the patients.
We consider that Borei-takusya-san is capable of wide application to the patients with edema under the waist, following our indications.

We examined the surgical procedure and long-term results in patients who underwent intraoperative re-do for the completion of mitral valve repair. Between March 1993 and July 1996, 81 patients underwent mitral valve repair for pure MR using TEE evaluation. Of these, 12 patients that were judged to have more than mild residual regurgitation (MRA≥2.0cm2 or MRL≥1.0cm) underwent intraoperative re-do. All of the patients were type 2, according to Carpentier's classification. Seven patients had degenerative disease and 2 had infective endocarditis. If the cause of residual MR was localized discoaptation, 5-0 suture plication with beating heart that increased the coaptation zone and resulted in decrease in the residual MR was useful. If the cause of residual MR was leaflet prolapse or dehiscence, intraoperative re-do was performed the cardiac re-arrest. Two patients of billowing valve underwent MVR and the other needed additional resection of leaflet, artificial chorda or suture. After intraoperative re-do, every procedure resulted in a reduction of MR except for 2 patients underwent MVR during the early postoperative stage, and of those all but one remaine no-to-mild MR in the late term (mean follow-up 26.2 months). In conclusion, 5-0 suture plication was effective for intraoperative re-do procedures, and basic mitral valve repair modification was necessary in about half of the cases. Intraoperative re-do was safely performed with no mortality or morbidity and it yielded good long term results. Intraoperative TEE evaluation was considered to be important.

The use of the radial artery (RA) for coronary artery bypass grafting (CABG) is increasing. This study describes mid-term results of the use of RA for CABG. Between March 1996 and March 1999, we performed 134 CABGs using RA or saphenous vein graft (SVG) for the left circumflex branch area or diagonal branch area. The mean age was 62.6±9.6 years in the RA group and 65.0±7.8 years in the SVG group. The average number of anastomoses was 2.7per patient. RA was anastomosed with the postero-lateral branch (PL) in 69 cases, with the obtuse marginal branch (OM) in 29 cases and with the diagonal branch (DB) in 10 cases. SVG was anastomosed with PL in 26 cases, with OM in 14 cases and with DB in 2 cases. The proximal anastomosis was made with the ascending aorta in all cases. No sequential bypass anastomosis was used in any case. The early patency rate of the grafts was 97.9% (93/95) in RA and 91.7% (33/36) in SVG. The clinically negative rate in the treadmill test (TMT) performed later was 99.0% (102/103) in RA and 90.9% (30/33) in SVG. The late patency rate of the grafts was 92.9% (13/14) in RA and 50.0% (3/6) in SVG. Perioperative death occurred in 5 cases. Late cardiac death occurred in 2 cases (0.02%) of the RA group and 1 case (0.03%) of the SVG group. The 3 year-survival rate free of cardiac events was 92.8% in the RA group and 80.9% in the SVG group. The use of RA for CABGs is not only effective for myocardial revascularization, but also can be expected to bring about good patency as a late result.

A 16-year-old girl with aortitis syndrome under treatment with a low dose of prednisolone was admitted because of severe headache and intermittent claudication. Angiography revealed diffuse stenosis of the thoracoabdominal aorta and the bilateral renal arteries. Extra-anatomical bypass grafting from the ascending to the abdominal aorta was first made with a 14mm woven Dacron graft through a midline sternolaparotomy. Bilateral renal arteries were difficult to dissect due to periarterial adhesion. Bypass grafting for the left renal artery could be performed with a 5mm external velour wrap-knit Dacron graft (Sauvage, Bionit); however, the right renal artery was so thin that bypass was made with a 4mm EPTFE graft which was demonstrated to be occluded by follow-up angiography 3 years after surgery. The postoperative course has been uneventful and she has been free from symptoms up to now. The good long-term function of the bypass graft from the ascending aorta holds promise for diffuse coarctation of the thoracoabdominal aorta due to aortitis syndrome.

The earlier the diagnosis of acute type A aortic dissection is made, the more frequent the complications of aortic root destruction and/or a compromised coronary artery are encountered. Only aortography is diagnostic in these lesions, however, recently this modality tends to be avoided in order to try to improve the survival rate of the patients by obtaining diagnosis by noninvasive modalities. Therefore, contrast-enhanced CT scans in 49 patients with aortic dissection were analyzed in order to detect the slightest signs suggesting aortic root lesions. In 4 of the 6 cases in which intimal flap was detected in the aortic root by CT and in 2 of the 14 cases with an aortic root more than 35mm in diameter, aortic root reconstruction and/or concomitant CABG were neccessary for the repair of the destroyed aortic root. The aortic root diameter was more than 40mm in 8 of 9 patients with aortic root destruction, with a mean value of 45.6±3.6mm (p<0.01). In summary, detection of a septum in the aortic root and/or an aortic root dilated more than 40mm on CT were important signs suggesting the dissection extending to the aortic sinus combined with aortic root destruction. In such cases aortic root reconstruction and/or concomitant CABG may be necessary.
