We present a rare case of mitral stenosis with bilateral pulmonary arteriovenous fistulae (PAVF). A 55-year-old female who complained of dyspnea did not have pulmonary hypertension. She underwent successfully mitral valve replacement with an artificial valve 2 months after transcatheter coil embolization for PAVF. The combination with mitral valve replacement and transcatheter embolization is regarded as a useful procedure for mitral valve disease associated with PAVF.

The diagnosis of ruptured dissecting limited abdominal aortic aneurysm was made in four cases. The sex ratio (M/F) was 1/3, and mean age was 63.5 years (from 53 to 78yr). Only one of these cases die due to intraoperative bleeding. Other three cases were discharged from our hospital. Intraluminal proximal anastomosis after fixed dissected aortic wall due to mattress suture and end to end anastomosis with reinforcement by Teflon felt were good results. The one case who was anastomosed simple intraluminal method has pseudoaneurysm in the proximal portion. It is important to diagnose preoperatively dissection and to make end to end anastomosis with Teflon felt.

We experienced a 51-year-old male case of CABG whose graftography one month after CABG revealed a 0.5cm venous bypass graft aneurysm. Anginal pain recurred in the eighth month after CABG. Re-graftography showed enlargement of the aneurysm and stenosis of the graft at the same site. Re-CABG was carried out successfully and his postoperative course was good. Venous graft aneurysm is a comparatively rare complication, and that of the present case was considered to be most ascribable to the fragility of the graft, caused by mediastinitis secondary to the first CABG. Thrombus formation was noted in the aneurysm, with a risk of causing rupture or myocardial infarction. Therefore, such graft aneurysms should be treated by re-CABG as soon as possible after detection.

A 27-year-old female with Marfan's syndrome underwent successful emergency surgery for rupture of an abdominal aortic aneurysm. Annulo-aortic ectasia with a saccular aneurysm of the aortic arch was revealed by angiography after the initial operation. Cabrol's operation with replacement of the aortic arch was performed. Because bleeding from the distal anastomotic portion was uncontrollable, the segment was ligated and an extra-anatomical bypass was performed from the ascending aortic graft to the bilateral femoral arteries. Intra-graft balloon pumping was carried out in the extra-anatomical bypass graft while the patient was in low cardiac output condition after the second operation. This was considered to be an effective circulatory assist procedure.

A 58-year-old man was admitted with pulsatile abdominal mass with fever and dull pain. Abdominal aortic aneurysm with left hydronephrosis due to obstruction of the left ureter was diagnosed by CT scanning. Aortic valve replacement was performed ten years previously for aortic regurgitation and recently his cardiac function deteriorated. On the 5th day after admission he suddenly suffered from hemorrhagic shock with massive melena. Emergency laparotomy was performed and ruptured abdominal aortic aneurysm was observed penetrating to the sigmoid colon with perianeurysmal abscess. The abdominal aorta was excluded and closed using two-layer sutures just below the renal artery, and bilateral common iliac arteries were also closed. The aneurysmal sac and the sigmoid colon were removed as a whole, and colostomy was made according to Hartmann's procedure. Permanent right axillo-bifemoral bypass graftiny was made to avoid infectious complications of the vascular graft. A successful vascular reconstruction was done without any complication of graft infection, however he died of cardiac failure due to dilated cardiomyopathy after 4 months postoperatively. We reported a successfully treated abdominal aortic aneurysm extending to the sigmoid colon with hemorrhagic schok.

Between 1984 and 1994, 58 patients underwent operations for type A aortic dissection. A sutureless ringed intraluminal graft was used in 9 of the 58 cases. The patients ranged from 47 to 74 years old (mean, 60.4 years). Six patients were discharged from the hospital and three patients died. The operative mortality rate for the 9 patients was 33.3% and for the other 49 patients it was 20.4%. Post-operative aortograms revealed a remaining false lumen in 5 of the 6 discharged patients. The result of the operation with the sutureless ringed intraluminal graft was not satisfactory. Therefore, we prefer to resect and replace the dissected aorta using the prosthetic graft rather than repair with the sutureless ringed intraluminal graft.

An 81-year-old woman with severe chest pain was admitted to our hospital. Computed tomography showed aortic dilation and a non-enhanced crescentic area in the ascending aortic wall, indicating a DeBakey type-II aortic dissection with thrombus. The ascending aorta was replaced with an impregnated knitted Dacron graft. Fresh clotted hematoma was found in the dissected ascending aortic wall, and the intimal surface was involved with a local atherosclerotic ulcer penetrating the media. Operative findings were compatible with intramural hematoma due to penetrating atherosclerotic ulcer described by Stanson et al. In the literature most penetrating atherosclerotic ulcers are located in the descending aorta, thus this case is rare.
8.A Case of Occlusion of the Abdominal Aorta at the Chronic Phase of Thrombosed Type A Aortic Dissection.

A 62-year-old woman was admitted for chest and back pains. She was found to have thrombosed type A aortic dissection by enhanced computed tomography. Since she had no clinical symptoms after her admission, she was discharged. Forty days after the admission, she returned with acute renal failure and ischemia of both lower extremities. Occlusion of the abdominal aorta was diagnosed and emergency axillobifemoral bypass was performed. Her renal function and the ischemia of both lower extremities improved dramatically and she was discharged 30 days after the operation. Axillobifemoral bypass is one of the most effective and least invasive operations in such cases.

A 39-year-old man received Bentall's operation for annuloaortic ectasia in July 1985. He was admitted with a high fever in July 1998. On the 2nd day of his admission, he suddenly suffered from headache and dizziness. Head computed tomography showed multiple low density areas in the right cerebrum and cerebellum. A transesophageal echocardiogram revealed massive vegetation around the prosthetic valve. The patient underwent emergency operation using cardiopulmonary bypass. The left ventricle outflow was almost occluded by thrombi. The prosthetic valve and graft were removed completely and replaced with a 24mm Gelseal® graft and a 23mm St. Jude Medical® valve. The right coronary ostium was reimplanted directly on the prosthesis, and the left coronary ostium was reinserted using a 10mm graft. The patient's intraoperative tissues grew S. aureus and parenteral antibiotics were administered for 5 weeks after surgery. The patient was discharged on the 45th postoperative day and is doing well 9 months after the operation.

1) The objectives of author's present study were 42, 245 patients with ratio of males to females of 7 to 3 in 44, 327 affected locations, covering the period of 23 years from the December of 1956 to the end of March of 1979.
2) All the injuries thus treated can be classified into 18, 815 (42.5%) of sprains, 11, 838 (26.7 %) of fractures, 9, 650 (21.8%) of lacerations, 2, 812 (6.4%) of contusions, 752 (1.7%) of dislocations and 460 (1.0%) of others.
3) Looking from auther's statistical study of the ski injuries in the past 23 years, the development of the ski equipments have largely effected on the ski injuries.
4) The lacerations on the head, face and arm are increased when the safety bindings have come into wide use. So, we expect the effect of the ski-stopper replacing the strap, in order to decrease the lacerations.
5) Injuries of the ankle have been decreased because of the plastic ski boots. Especially, “the ski fractures”, or, the abducted and external rotated fractures of the lateral malleolus are decreased remarkably.
6) The knee sprains, or, the ligamentous strains of medial colateral ligament of knee joint have been increased, because the stiff and high backed plastic ski boots have come into wide use.
7) Fractures of the lower legs and boot top fractures have been increased, according the development of the ski boots, such as from the leather boots to buckled boots to plastic boots.
