Diagnosis of Renal Artery Occlusion by Duplex Sonography and Successful Lysis Therapy

Abstract

A case of partial renal artery occlusion in a 44-year-old man is reported. Diagnosis was established by Duplex sonography and confirmed by digital subtraction angiography. Subsequently performed local lysis therapy with recombinant tissue plasminogen activator achieved partial revascularization. Doppler evaluation of renal blood flow is useful to detect renal infarction.

Successful Fibrinolytic Therapy Using Tissue Plasminogen Activator in Acute Renal Failure due to Acute Thrombosis of Bilateral Renal Arteries

“…In this report, renal scintigraphy was indeed effective. Although routine renal ultrasonography is not so valuable in detecting acute embolism of renal artery, duplex ultrasonography may permit immediate detection of suspected renal artery occlusion in routine ultrasound examination [4]. Renal artery occlusion is often detected too late for any therapeutic approach.…”

“…However, the appropriate usage of t-PA for the fibri nolytic therapy of acute thrombosis of renal artery has not been determined. t-PA has been used for acute thrombo sis of renal artery in only two reports [4,9] in which t-PA was intra-arterially administered. Our case has been fol lowed up and maintained a stable renal function for a far longer period than the above cases.…”

Renal Artery Embolism Diagnoed by Abdominal Ct and Successfully Managed Conservatively After Thirty-Six Hours: A Case Report.

“…Different authors [13] suggest that the duration of renal ischemia is an important factor for recovery of renal function, however successful late revascularization and renal recovery can be can be reversed after longer periods of occlusion [6,8,14,15] which may extended up to 5 days ( 8). In reality, this almost certainly reflects the extent of collateral renal circulation [15] .…”
