PURPOSE: This study was designed to evaluate usefulness of intravenous digital subtraction angiography (IV-DSA) in detection of peripheral arterial obstructive disease(PAOD) and in follow-up of percutaneous transluminal angioplasty(PTA). MATERIALS AND METHODS: 35 Patients who had clinical symptoms and signs of compromised lower extremity perfusion, was screened with IV-DSA and then performed confirmative conventional angiography. We obtained sensitivity, specificity and accuracy of IV-DSA by comparing the findings of IV-DSA with those of conventional angiography. 21 patients who had been performed successful PTA, were foliowed-up with IV-DSA in 3, 6, 12months. We studied patency rate and factors that influenced restenosis. RESULTS: The sensitivity, specificity and accuracy of IV-DSA were 100%, 97%, 97% in lilac artery, 92%, 96%, 93% in femoropopliteal artery, 85%, 75%, 70% in proximal tibioperoneal artery retrospectively. IV-DSA follow up after PTA showed patency rate of 67% in first 3month, 67% in 2nd 3month, 60% in next 6month. Longer length and more irregular surface of the stenotic site, and higher incidence of run-off of vessel and of residual stenosis in the patients with restenosis were noted. CONCLUSION: High sensitivity, specificity and accuracy of IV-DSA in evaluating PAOD suggest that IV-DSA is useful in screening, planning therapy and following up after PTA.

From January to December 1984, 191 patients with associated ventricular septal defect(VSD) were studied in the cardiac cathetherization laboratory. Among theses 191 cases, 58 cases(30.4%) of subpulmonic VSD were identified by angiocardiography. Among the 59 cases of subpulmonic VSD, 12 cases(20.6%) were complicated with aortic infficiency(AI). The relative frequency of subpulmonic VSD increased with the increase of age and the frequency of complication of AI with the subpulmonic VSD also increased with the increase of age. The amount of left to right shunt in the patients with subpulmonic VSD and AI was small and Qp/Qs ratio was less than 2.0 in all of the 12 cases. Among the 12 patients 4 cases had a pressure gradient greater than 20 mmHg across the infundibular region of the right ventricle.

Successful percutaneous transluminal angioplasty (PTA) of an internal mammary artery graft was performed in a 40 year old male patient who had recurrent angina soon after bypass surgery. Coronary angiography showed total occlusion of proximal portion of the left anterior descending artery and normal right coronary artery. Angiography of the left internal mammary artery graft revealed a tight stenosis (90% diameter narrowing) in the mammary artery at its insection into the left anterior descending artery.Angiography after the angioplasty demonstrated a widely patent graft (residual stenosis 10%) and translesional pressure gradient was 10 mmHg.

A case of invasive cribriform carcinoma of the breast is presented with fine need- le aspiration cytologic features. The aspiration was performed from a papable 2.0cm mass in the upper outer quadrant of the right breast in a 53 year-old woman. The aspirate showed cellular smear composed of larger three dimensional tight clusters, smaller monolayered loose clusters, and many individual cells on the clean background. In the clusters, the tumor cells were bordering central lumina, quite similar to the cribriform in histology. The tumor cells in the clusters and individual tumor cells had uniform, small and round nuclei. The chromatin was finely granular, and nuclear membrane was smooth. No discernible nucleoli were present (nuclear grade 1-2). Unless the abundance of individual cells and the cribriform growth pattern are recognized in the smear, the cytologic diagnosis of invasive cribriform carcinoma is difficult.
