| Popis: | From 6% to 25% of primary renal carcinomas are either hypovascular or avascular and are the major source of false negative angiography. High-dose renal pharmacoangiography, a valuable adjunct to conventional angiography, combines a renal vasodilator, acetylcholine, with a high dose of contrast medium. High-dose renal pharmacoangiography improves the diagnosis of hypovascular mass by enhancement of tumor vessels, increase of tumor stain, and better opacification of main and collateral renal veins. During a 4 year period, 20 hypovascular renal neoplasms were studied and successfully diagnosed preoperatively by this method. |
