Two cases of renal artery embolism treated by selective intra-arterial infusion of tissue plasminogen activator (t-PA) are reported. A 74-year-old woman with atrial fibrillation presented with left flank pain of 54-hour duration. Selective renal angiography revealed embolic obstruction of multiple segmental arteries in the left kidney. She was treated by one-shot intra-arterial t-PA infusion (8,000,000 units) and intravenous heparinization (25,000 units/3 days). Although fibrinolysis was successful except for most distal arterial branches, complete recovery of renal function was not obtained. A 66-year-old man presented with complete obstruction of left main renal artery. He had hyperthyroidism and atrial fibrillation. At 75 hours after onset of left flank pain, he was treated by one-shot intra-arterial t-PA infusion (18,000,000 units) and intravenous heparinization (4,000 units/24 hours). His renal function was recovered completely. Selective intraarterial t-PA infusion is considered an effective treatment for renal artery embolism.

Renal vein thrombosis can occur as a complication of nephrotic syndrome. We present the case of a young man with nephrotic syndrome caused by minimal change disease who developed acute inferior vena cava and left renal vein thrombosis. He was treated initially with intravenous heparin. Because of the persistence of severe left flank pain and gross hematuria, local infusion of recombinant tissue plasminogen activator was tried, with resolution of thrombi and subsidence of symptoms. Functional preservation of the involved kidney is good, as indicated by Tc-99m DMSA scan (involved kidney, 47.4%; uninvolved kidney, 52.6%). Anticoagulation is usually recommended as the treatment of choice in renal vein thrombosis. We believe that in cases with critical presentations, such as bilateral involvement, extension into inferior vena cava, acute renal failure, pulmonary embolism or severe flank pain, thrombolytic therapy should be considered as a second-line treatment if good response is not obtained with heparin.

A 55-year-old woman affected by mitralism presented with severe right flank pain of sudden onset. Biochemical examinations showed elevated serum lactate dehydrogenase, and abdominal enhanced computed tomography (CT) demonstrated hypoperfusion of the right kidney. Infarction of the right kidney was highly suspected, and she was immediately treated by systemic intravenous injection of 12,000,000 units of tissue plasminogen activator (tPA) per day for 3 days and 120,000 units of urokinase per day for 8 days. After the thrombolytic therapy, abdominal enhanced CT revealed marked improvement of enhancement of right renal parenchyma and decrease of serum LDH. Although thrombolytic therapy with selective intraarterial infusion is considered to be a useful treatment modality for renal infarction, systemic administration of tPA may also be effective judging from the clinical course of the present case.

Renal artery embolism (RAE) is a rare disease. Urgent treatment is necessary, as ischaemia can cause irreversible kidney damage in 60 to 90 minutes. RAE frequently clinically manifests as a pain similar to renal colic. Source of embolus is predominantly the heart at atrial fibrillation. Laboratory findings are unspecific. Ultrasonography with color Doppler imaging is essential. Kidney perfusion is low and upper urinary tract is undilated. Renal function can be recognized by intravenous urography and at renal scintigraphy. In angiography, renal artery is closed with thromboembolus. With no delay, transcatheter clot aspiration should be performed and fibrinolytic agents (tissue plasminogen activator) should be topically administered. Continual heparinisation and later warfarinisation should follow. In spite of successful revascularisation, parameters of kidney function can almost never reach that prior the RAE and shrinkage of kidney becomes a frequent consequence. Treatment can be successful even in patients with renal occlusion lasting over 90 minutes, since occlusion is often incomplete or significant collateral blood supply exists. In conclusion, renal artery embolism must be considered in cases of flank pain in patients with certain risk actors (especially atrial fibrillation). Ultrasonography with color Doppler imaging and urgent angiography of the renal artery are necessary in these cases. Thromboembolus can be then aspirated, and kidney perfused with fibrinolytic agent.
