Spontaneous Renal Artery dissection revealed by helical CT angiography
European Radiology, 2000Co-Authors: J.f. Paul, J F Blancher, Marc Sapoval, Jacques Blacher, Mona Safar, J.-C. GauxAbstract:Spontaneous Renal Artery dissection is rare and may be misdiagnosed because its clinical presentation is confusing. Diagnosis is usually made by intra-arterial angiography. We report a case where a spontaneous Renal Artery dissection was initially misdiagnosed as a Renal abscess. Diagnosis was made later with helical CT for suspicion of Renal Artery stenosis in a patient with recent onset of hypertension. This unusual case shows that helical CT can be useful for non-invasive diagnosis of Renal Artery dissection.

Percutaneous transluminal angioplasty and surgery of the Renal Artery.
European Journal of Vascular Surgery, 2005Co-Authors: Andrew C. NovickAbstract:The management of patients with Renal Artery disease has changed in recent years. This has occurred due to the advent of PTA as an effective method of treatment for certain patients, an enhanced appreciation of advanced atherosclerotic Renal Artery disease as a correctable cause of Renal failure, and improved results of surgical revascularisation in both older patients with severe aortic atherosclerosis and younger patients with branch Renal Artery disease. PTA currently yields excellent results and is the treatment of choice for patients with fibrous dysplasia of the main Renal Artery and non-ostial atherosclerotic lesions. Most reports in the literature indicate that surgical revascularisation provides more effective therapy for patients with ostial atherosclerotic lesions. Surgical revascularisation also remains the treatment of choice for the majority of patients with branch Renal Artery disease, a Renal Artery aneurysm, Renal Artery occlusion, and recurrent Renal Artery stenosis after failed PTA or surgery. Excellent clinical results can be achieved with both PTA and surgical revascularisation in properly selected patients.

Pheochromocytoma coexisting with Renal Artery lesions.
The Journal of urology, 2000Co-Authors: Inderbir S. Gill, Anoop M. Meraney, Emmanuel L. Bravo, Andrew C. NovickAbstract:Purpose: Physiologically significant Renal Artery lesions in the presence of a pheochromocytoma comprise a confounding factor which may impact on the hypertension cure following excision of the pheochromocytoma. We present 10 cases of these dual lesions and review the literature on this entity.Materials and Methods: From 1952 to 1999, 269 patients were diagnosed with pheochromocytoma at our institution. Hospital charts of these patients were reviewed retrospectively to identify those with coexisting Renal Artery stenosis. A Medline search was performed to review the available literature.Results: Of the 269 patients with pheochromocytoma 10 (3.7%) had coexisting Renal Artery lesions, including Renal Artery stenosis in 8, Renal Artery aneurysm in 1 and postangiographic dissection occlusion in 1. Pheochromocytoma was adRenal in 8 cases and ectopic in 2. Of the patients 9 have been treated to date by adRenalectomy in 4, nephroadRenalectomy in 3, adRenalectomy plus lysis of Renal Artery adhesions in 1 and adre...

Management of Renal Cell Carcinoma with Coexistent Renal Artery Disease
The Journal of Urology, 1993Co-Authors: Steven C. Campbell, Andrew C. Novick, Stevan B. Streem, Eric A. KleinAbstract:AbstractCoexistence of Renal cell carcinoma and Renal Artery disease is an unusual and challenging problem. From 1969 to 1991, 34 patients presented with localized Renal cell carcinoma and Renal Artery disease affecting all of the functioning Renal parenchyma. These patients represented 4 categories: 1) a solitary kidney with Renal cell carcinoma and Renal Artery disease (5), 2) bilateral Renal cell carcinoma and coexistent Renal Artery disease (5), 3) unilateral Renal cell carcinoma and contralateral Renal Artery disease (13), and 4) unilateral Renal cell carcinoma and bilateral Renal Artery disease (11). Atherosclerosis was the most common cause of Renal Artery disease (30), followed by medial fibroplasia (2), Renal Artery aneurysm (1) and arteriovenous malformation (1). A total of 23 patients (68%) presented with azotemia (serum creatinine 1.5mg./dl. or more) and 11 (32%) presented with hypertension.All patients underwent complete surgical excision of Renal cell carcinoma. A nephron sparing operation w...

Spontaneous Renal Artery thrombosis associated with altered mental status.
Annals of Emergency Medicine, 1992Co-Authors: Jack P Campbell, Paul W LaneAbstract:Renal Artery thrombosis is much less common than Renal Artery occlusion by emboli. When it does occur, it is usually a result of blunt abdominal trauma or a thrombus superimposed on an atherosclerotic plaque. Numerous other factors have been associated with Renal Artery thrombosis. Spontaneous Renal Artery thrombosis is a rare phenomenon in itself. This case represents spontaneous Renal Artery thrombosis associated with an altered mental status. Clinical features with suspected etiologies are reviewed. Recommendations for future evaluations are given.

e0672 Treatment of atherosclerotic Renal Artery stenosis involving Renal Artery bifurcations
Heart, 2010Co-Authors: Zheng Bin, Yan HongbingAbstract:Objective To investigate the efficacy of kissing stent or kissing balloon technique for Renal Artery bifurcation with atherosclerotic Renal Artery stenosis. Methods There were five patients included, who were with atherosclerotic Renal Artery stenosis involving Renal Artery bifurcation. Results The reference vascular diameter of main Renal Artery was 5.6±0.4 mm. The reference vascular diameter of Renal Artery distal to bifurcation were 3.4±0.4 mm and 3.6±0.5 mm. Kissing balloon technique was used in three patients with obvious residual stenosis, and kissing stent technique was used in two patients without obvious residual stenosis. Blood pressure was lowered in two patients, unchanged in three patients. Serum creatine was lowered in one patient. Conclusion As for angiographic residual stenosis, it seems that kissing stent technique is more efficacious than kissing balloon technique.
