Abstract:
DSA(Digital Subtractin Angiography) is a valuable diagnostic imaging method in many clinical fields, includingranal-related conditons. Sixty four renal DSA examinations were performed in 59 patients with renal-relateddiseases from Jan. 1984 to Dec. 1985. Summary of these were as follows: 1. Intraarterial (IA)-DSA is performed in6 cases, intravenous(IV)-DSA in 58 cases. In 58 Examinations of IV-DSA, diagnostic image quality is obtained in 51cases(88%). 2. In investigations of a possible renovascular etiology of hypertension, IV-DSA,is a safe, sensitiveand accurate method. On screening for evaluation of renovascular hypertension, RSP should be replaced with IV-DSA,because IV-DSA is moe sensitive and accurate and can detect not only anatomic change of renal arttery but alsofunctional hemodynamic change. 3. IV-DSA is valuable in diseases with morphologic changes of vessels. Incharacterization of a known renal mass, and evaluation of hematuria, suspected aneurym and renal trauma, IV-DSA isvery useful diagnostic imaging modality. 4. In evaluation of potential renal donors, IV-DSA is an accurate andsafe method with 82.4% of accuracy. IV-DSA also is useful in follow-up of allograft recipients. 5. Ininvestigation of diabetic nephropathy, glomerulonephritis, pyelonephritis, IV-DSA is little helpful. 6. Theadvantages of DSA are well known, particularly post-procedure process using computer programs is helpful forobtaining informations of hemodynamic change or time-sequence-curve of density etc. More technical improvementwith this modality is required for improvement of the image quality and resolution. And more accumulation ofclinical experience is required in order to increase the diagnostic accuracy.
