A 53-year-old man with stable coronary disease and dyslipidemia was admitted with sudden pain of severe intensity in the left flank, initiated at about 4 hours prior, with irradiation to the pelvic region, associated with vomiting. He was evaluated in the emergency department, and was suspected to have pyelonephritis and/or renal lithiasis. At physical examination, he had positive Giordano sign and no fever. Hemogram showed leukocytosis and shift to the left, non-infectious routine urine, and renal injury (creatinine, 1.4 mg/dL). An empiric antibiotic was started. He mentioned palpitations the night before. Electrocardiogram at admission showed sinus rhythm and absence of acute ischemia signs. He kept refractory pain, even after opioid analgesia. A computed tomography scan of the abdomen was performed with contrast, showing left renal hypoperfusion and a suggestive image of thrombus in the left renal artery (Figure 1).

Before persistent pain, we chose to do a renal arteriography to evaluate percutaneous approach; it highlighted a high thrombotic load in the left renal artery (Figure 2; Videos 1 and 2) with a decrease in the nephrographic effect. In view of the patient’s clinical picture and angiographic findings, we chose local intra-arterial thrombolysis.

We performed selective catheterization of the left renal artery, followed by bolus infusion of alteplase 15 mg by microcatheter (Video 3). More diluted injections were then given over a period of 30 minutes for a total of 50 mg. Immediate arteriography showed a maintained pattern, but the patient experienced a slight improvement in the pain. After 6 hours of the procedure, the patient was asymptomatic.

During hospitalization, echocardiogram (Figure 3) and Holter monitor were requested. Previous cardiac catheterization showed anterior descending  artery with a discrete lesion and small diagonal branch with a severe lesion, and we opted for clinical treatment. Left ventriculography and echocardiogram revealed thrombus at the apex and preserved global function. Holter monitor showed absence of paroxysmal tachyarrhythmias.

New renal arteriography was performed after 5 days, and showed no evidence of thrombus, with improvement of the nephrographic effect (Videos 4-6). At hospital, he was kept under full anticoagulation with enoxaparin. He was discharged in good clinical condition with normal renal function. Rivaroxaban, bisoprolol, enalapril, and rosuvastatin were prescribed.
