BACKGROUND: Although surgical angioplasty for isolated coronary ostial stenosis is assumend as an alternative approach to CABG, the clinical features of isolated coronary ostial stenosis, postoperative complications and follow-up angiographic results would have not been well studied. METHODS: We retrospectively studied 24 patients (female : male = 20 : 4, mean age 50.0 +/- 12.3 yr) who underwent surgical angioplasty for isolated coronary ostial stenosis using patch ( 22 fresh autologous pericardium, 2 saphenous vein) during the period of March 1990 through February 1998. Repeat coronary angiography (16 patients) and echocardiography (24 patients) were performed. Aortic regurgitation was evaluated semiquantitatively (Grade I - Grade IV). RESULTS: There were 3 deaths after surgical angioplasty. One death was due to acute coronary dissection perioperatively, the second due to low cardiac output syndrome 2 weeks post-surgery, and the third due to traumatic panperitonitis 10 months post-procedure. Angina recurred in 4 patients and the remaning 18 patients were symptom-free. Repeat angiography (19.3 +/- 20.7 Mo) showed widely patent ostium with excellent run-off except 2 patients (1 distal patch stenosis, 1 ostial restenosis in Takayasu's arteritis). The third symptomatic patient was proven to have coronary spasm by ergonovine test. AR increased in the fourth patient (Grade II -> III) with patent ostium. CONCLUSION: Surgical angioplasty may be feasible and alternative operative method to CABG for isolated coronary ostial stenosis. It should however be noted that postop AR can develop and/or increase. Further investigation is needed to evaluate the clinical significance of the AR.

BACKGROUND: Endocrine pancreas tumor is a rare disease which incidence is less than 2% of all pancreatic tumors. But it comprises various types of tumor and usually secretes several hormones from one type of tumor although the patient with this tumor complains of sole symptom associated with only one hormone. The mechanism and clinical significance of multiple hormone secretion in the endocrine pancreas tumom are not yet clearly defined. METHODS: We analyzed retrospectively the clinicopathologic features of 20 cases which were operated at Seoul National University Hospital during the period between February 1989 and May 1998. RESULTS: The most common tumor was insulinoma (13 cases) and the second most common tumor was nonfunctioning tumor (6 cases). There was one case of somatostatinoma. Most of the patients with insulinoma complained of neuroglycopenic symptoms. There were 9 cases (45.0%) in which the tumors secreted more than two kinds of hormones, 7 cases in insulinoma, 2 cases in nonfunctioning tumors. Whether the tumor secreted multiple hormones was detected by the method of immunohistochemical staining. Though the tumors secreted more than two kinds of hormones, the patients with the tumors complained of symptoms which were associated with the cell type most strongly stained by immunohistochemical method. Whether or not the tumors secreted multiple hormones was not associated with the pathologic features such as tumor size, histologic patterns of the tumor, status of tumor cell differentiation and malignancy. CONCLUSION: From this results, we suggest that endocrine tumors of the pancreas secreted multiple hormones not by the mechanism of dedifferentiation from already differentiated endocrine cells but by the mechanism of neogenesis of multipotent islet stem cells. Since the relationship between the function of multiple hormone secretion in the endocrine pancreas tumors and islet stem cell would be significant, further study should be needed to find out the function of stem cells and application of stem cells to clinical use.

Angioid streaks are easily recognized although relatively rare. They are typically described as irregularly radiating lines extending from the peripapillary area peripherally. They are usually bilateral, and are characteristically found in the posterior pole. Angioid streaks may occur alone or in association with various systemic diseases. Pseudoxanthoma elasticum is a relatively uncommon disorder of elastic tissue involving dermal, ocular, gastrointestinal, and cardiovascular tissues. We examined a case of angioid streaks associated with pseudoxanthoma elasticum found in a 31 year-old female and presented a brief review of the relating literatures.
