ABSTRACT

A 74-year-old man having a right refractory foot ulcer was referred to our hospital with a diagnosis of arteriosclerosis obliterans. Angiography of the lower extremities showed occlusive lesions in the middle popliteal artery and lower-leg arteries. Preoperative examination revealed decreased cardiac function and severe stenosis of the left and right coronary arteries. Therefore, we first performed coronary artery bypass grafting, followed by revascularization of the lower limbs at a later date. Owing to the lack of suitable autologous vein grafts, our procedure of choice was popliteal endarterectomy via a posterior approach with short saphenous vein angioplasty. The patient's foot ulcer healed completely following surgery. His postoperative course was uneventful, and he remained symptom-free during a 1-year follow-up.

ABSTRACT

OBJECTIVE: We conducted a retrospective, multi-institutional, collaborative study to accumulate cases of neuroendocrine carcinoma of the endometrium, to clarify its clinicopathologic features, treatment, prognosis and prognostic factors to collate findings to establish future individualized treatment regimens. To our knowledge, this is the largest case study and the first study to statistically analyze the prognosis of this disease. METHODS: At medical institutions participating in the Kansai Clinical Oncology Group/Intergroup, cases diagnosed at a central pathologic review as neuroendocrine carcinoma of the endometrium between 1995 and 2014 were enrolled. We retrospectively analyzed the clinicopathologic features, treatment, prognosis and prognostic factors of this disease. RESULTS: A total of 65 cases were registered from 18 medical institutions in Japan. Of these, 42 (64.6%) cases were diagnosed as neuroendocrine carcinoma of the endometrium based on the central pathological review and thus included in the study. Advanced International Federation of Gynecology and Obstetrics stages (stage III and IV) and pure type small cell neuroendocrine carcinoma cases had a significantly worse prognosis. Upon multivariate analysis, only histologic subtypes and surgery were significant prognostic factors. Pure type cases had a significantly worse prognosis compared to mixed type cases and complete surgery cases had a significantly better prognosis compared to cases with no or incomplete surgery. CONCLUSION: Our findings suggest that complete surgery improves the prognosis of neuroendocrine carcinoma of the endometrium. Even among cases with advanced disease stages, if complete surgery is expected to be achieved, clinicians should consider curative surgery to improve the prognosis of neuroendocrine carcinoma of the endometrium.

ABSTRACT

A 52-year-old man presented with a pulsatile mass in the right groin. He had undergone lumbar sympathectomy and aorto-right femoral artery bypass using an 8mm Microvel double velour graft, 14 years previously, for aortoiliac occlusive disease caused by thromboangiitis obliterans. Based on a clinical diagnosis of an anastomotic aneurysm, an operation was performed. When the aneurysm was incised, it was found that the anastomosis of the graft to the femoral artery was intact and that the graft itself had a defect, 3cm in size on the anterior wall, 1.5cm proximal to the distal anastomosis. The final diagnosis was a nonanastomotic false aneurysm due to prosthetic graft failure. The failed portion of the graft was resected, and a 10mm Hemashield Gold woven double velour graft was interposed between the old graft and the right femoral artery. Generally, arterial grafts below the groin are subject to high levels of mechanical stress, and graft failure is not uncommon. Vascular surgeons should keep in mind that graft failure is not rare in patients with long-standing prosthetic grafts.

ABSTRACT

The approach for the heart and proximal aorta in a patient with a tracheostomy poses difficult problems such as mediastinitis and inadequate operative exposure. We report a case of successful surgical treatment for type A aortic dissection in a patient with tracheostomy using a Y shaped skin incision and median full-sternotomy. A 63-year-old woman with a tracheostomy was referred to our hospital because of type A thrombosed aortic dissection and cardiac tamponade. At first we treated the patient conseservatively, but follow-up CT taken on the 20th day after onset revealed that false lumen of the ascending aorta was patent and the size of ascending aorta had increased to 6cm in diameter. We therefore performed hemiarch replacement (24mm Hemashield gold graft) through a Y shaped skin incision and median full-sternotomy. The postoperative course was uneventful and she was discharged on the 19th postoperative day.

ABSTRACT

Celiac artery aneurysm (CAA) is very rare. We report a case of CAA with type IIIb aortic dissection (DA) which was treated surgically. A 60-year-old man who had an abnormal enlargement of the aorta on abdominal ultrasonography was admitted to our hospital. Angiography and CT scan revealed CAA with type IIIb DA. His general condition was stable and surgery was performed electively. The CAA was exposed through a median laparotomy. It was found to be about 3cm in diameter. As vascular reconstruction seemed difficult and the proper hepatic artery showed good pulsation after clamping the common hepatic artery, we decided to perform celiac artery aneurysmectomy without vascular reconstruction. Except for transient liver dysfunction, there was no other complication and he was discharged on the 24th postoperative day. During surgery for CAA, when collateral perfusion from the SMA to the liver is adequate, it seems that vascular reconstruction is not always necessary as shown by this case.

ABSTRACT

We reviewed 223 cases of surgical treatment for abdominal aortic aneurysm in octogenarians in this hospital between 1981 and 2000, and investigated the characteristic features, complications, and indications of the operation. The cases were divided into two age groups. Group O included 23 cases of octogenarians, and Group Y included 200 cases of patients under 80 years old. The average age was 68.6 years old in group Y (33-79 years old), and 83 years old in group O (80-93 years old). The hospital mortality rate was 0% in elective operation cases. In emergency operation case, Group O had a hospital mortality rate of 57.1%, significantly higher than the 6.1% for group Y. The hospital mortality rate was 17% in group O and 0.5% in group Y. The rate of emergency operation case was significantly higher in group O (30.4%) compared to group Y (16.5%). As for the preoperative complications, group O had more cases of renal dysfunction, COPD and gastrointestinal complication. As for the coronary artery disease and other cardiovascular complications, there were no significant differences between the groups. In the postoperative complication, group O had more cases of ileus, pneumonia, and cardiovascular disease. These complications were fatal in group O. These results suggest that surgical treatment for abdominal aortic aneurysm was performed safely in both groups for elective operations. Because the results of emergency operations are poor, early diagnosis and treatment seem to be important for the improvement of operative results.
