Digital subtraction angiography in renal transplant recipients

Abstract

The renal transplant vascularity of 72 patients was investigated by intravenous digital subtraction angiography (IV DSA). The procedure was combined with selective venous renin sampling of the transplant and native kidneys to identify the source of hypertension in these patients. Abnormalities were found on IV DSA examination in 26 patients, of whom 7 had graft artery stenosis, 7 had diffuse intrarenal narrowing, 9 had lower pole ischemia, and 3 had aneurysmal dilatation. The combined outpatient procedure was well tolerated by all patients with no complications nor incidence of proteinuria.

Digital Subtraction Angiography of the Kidney

“…DSA techniques have been widely discussed in the medical literature and so have their various clinical applications (Arnold et al, 1981 ; Harrington et al Maffesanti, 1983). In the urological field the clinical applications of DSA are numerous, and the method has in fact been used in the pre-operative staging of renal tumours (Cronan et al, 1982;Engelmann et al, 1984;Prager et al, 1984), in the screening of arterial hypertension (Hillmann et al, 1982b;De Somer et al, 1984;Schorner et al, 1984;Wilms et al, 1986), and in post-operative follow-up controls after vascular surgery (Novick et al, 1982); also in the pre-operative and post-operative investigation of patients who have undergone a renal transplant (Flechner et al, 1983;Irving and Khoury, 1983;Rath et al, 1984;Tessier et al, 1986) and of their donors (Hillmann et al, 1982~). DSA has also proven valuable in the field of interventional radiology (Chang er al., 1984).…”

Digital subtraction angiography: The intravenous approach

“…In the last 2 years, with improved equipment, it has become a widely accepted method to check up patients with renal hypertension ( Fig. 2) and for follow-up of patients with renal artery stenosis, who were treated by percutaneous transhiminal angioplasty (PTA) or bypass-surgery [12]. Iv-DSA was also successfully used in patients with renal transplants (Fig.…”
