“…The limitations of peripheral IVDSA can, in part, be overcome by central catheter IVDSA giving a more compact and concentrated bolus, and thus the possibility of more injections in several projections (61,62). The combination of IVDSA with selective renal vein sampling for renin determination seems to be a rather successful procedure in selected patients.…”

“…The immediate importance of the contrast medium reduction is important to greatly diminish the risk of nephrotoxicity as well as to eliminate pain and involuntary reflexes which may produce patient motion. Catheters can be placed in the aorta as well as in subselective positions (61,62). Following IADSA one may proceed with angioplasty in the same session.…”

Hypertension constitutes a major health problem and the challenge is to identify patients having 'surgically' curable renal vascular disease among the majority with so-called essential hypertension. The best of unsatisfactory diagnostic tests are renography and plasma renin activity both before and during angiotensin II blockade. The necessity of better screening tests has increased because of the recent advances in surgical techniques and especially percutaneous transluminal renal angioplasty. The latter has definitely become the method of choice for correction of suspected hemodynamically significant artery stenoses whenever technically feasible. With improved angioplasty techniques the risk of treating renal artery stenosis without hemodynamic and clinical importance (so-called cosmetic repair) has increased. Unfortunately randomized trials including surgery versus angioplasty are not available. It should be kept in mind that only after correction of the stenosis is achieved and the blood pressure has become normal, can the diagnosis of renovascular hypertension be made with certainty.

“…The contrast sensitivity is 10 to 20 times greater than that of conventional radiographic techniques resulting in a six-fold reduction in contrast medium necessary to be used (70). Catheters can be placed in the aorta as well as in subselective positions (61,62). Catheters can be placed in the aorta as well as in subselective positions (61,62).…”

Right anterior oblique intravenous digital subtraction ventriculograms and selective coronary angiograms were performed on 71 consecutive patients. The intravenous ventriculograms were reviewed by two blinded observers with close examination of the right and left anterior descending coronary arteries. These were considered abnormal if they failed to opacify or if luminal irregularities suggested greater than 50% obstruction. Significant (greater than 50% obstruction) occlusions of the right coronary artery were found in 16 patients according to a blinded reading of the selective angiograms. The observers correctly identified 13 of these on the digital subtraction ventriculograms (sensitivity 81%). Of the 55 nondiseased right coronary arteries, correct identification was made in 47 (specificity 85%). Likewise, 17 patients had angiographically significant obstructions of the left anterior descending coronary artery and 15 were correctly identified by digital subtraction ventriculography (sensitivity 88%). However, only 20 of the 54 nondiseased left anterior descending coronary arteries were correctly identified (specificity 37%). Nonopacification or visualization of a severe obstruction of the right coronary artery is a useful finding and should be sought during examination of routine intravenous digital subtraction ventriculograms. This technique is not adequate at the present time to replace selective coronary arteriography in the assessment of coronary anatomy.
