Bilateral renal artery stenosis as a cause of refractory intradialytic hypertension in a patient with end stage renal disease.

BMC Nephrol 2019 Jan 14;20(1):19. Epub 2019 Jan 14.

Section of Nephrology, Department of Medicine, Regina General Hospital, 1440, 14th Avenue, Regina, S4P 0W5, Canada.

Background: We report a 61-year-old female with end-stage renal disease (ESRD) secondary to polycystic kidney disease (PKD) complicated by intradialytic hypertension (IDH). Increased sympathetic drive leading to increased stroke volume and/or vasoconstriction with an inappropriate increase in peripheral vascular resistance (PVR) has been postulated to be the cause of IDH.

Case Presentation: Attempts to control her blood pressure by reducing her goal weight; increasing dialysis times/ frequency and decreasing her sodium concentrate in the dialysis fluid were unsuccessful. Read More

Understanding and managing atherosclerotic renovascular disease: still a work in progress.

F1000Res 2018 29;7. Epub 2018 Nov 29.

Departments of Physiology and Biophysics, Medicine, and Radiology, University of Mississippi Medical Center, 2500 North State Street, Jackson, MS 39216-4505, USA.

Atherosclerotic renovascular disease (ARVD) is an unresolved therapeutic dilemma despite extensive pre-clinical and clinical studies. The pathophysiology of the disease has been widely studied, and many factors that may be involved in progressive renal injury and cardiovascular risk associated with ARVD have been identified. However, therapies and clinical trials have focused largely on attempts to resolve renal artery stenosis without considering the potential need to treat the renal parenchyma beyond the obstruction.

Treatment of critical hand ischemia via orbital atherectomy and focal force balloon angioplasty: A mini-review.

Cardiovasc Revasc Med 2018 Apr 6. Epub 2018 Apr 6.

Cardiovascular Systems, Inc., St. Paul, MN, United States.

Calcified lesions in below-the-elbow (BTE) arteries are common in patients with diabetes or end-stage renal disease and can lead to critical hand ischemia (CHI). Treatment of calcified lesions with atherectomy has proved useful in the lower extremities, however, atherectomy in the upper extremities and especially BTE, is not typically considered due to the small vessel size. We review and discuss these studies along with other CHI-related articles and also present a case of a severely calcified ulnar artery lesion treated with orbital atherectomy and plain Chocolate balloon angioplasty.

Adjunctive visceral artery chimney in patients undergoing Zenith Fenestrated aortic repair.

J Vasc Surg 2018 Dec;68(6):1688-1695

Division of Vascular Surgery, Department of Surgery, Indiana University School of Medicine, Indianapolis, Ind. Electronic address:

Objective: Visceral artery chimneys have been employed as an adjunct to endovascular aneurysm repair (EVAR) to treat short-neck infrarenal and juxtarenal aortic aneurysms for more than two decades. With the widespread introduction of fenestrated endovascular aneurysm repair by the Food and Drug Administration-approved Zenith Fenestrated endograft (ZFEN; Cook Medical, Bloomington, Ind) to the United States in 2012, clinicians gained the ability to apply the chimney technique to these custom devices for difficult anatomy. The purpose of this report was to demonstrate feasibility and to provide evidence on the performance of chimneys for the treatment of complex juxtarenal aneurysms that could not be adequately treated with ZFEN alone.

Differences in renal hemodynamics and renin secretion between patients with unifocal and multifocal fibromuscular dysplasia.

J Hypertens 2018 Aug;36(8):1729-1735

Department of Internal Medicine.

Objective: Fibromuscular dysplasia (FMD) can be classified in a multifocal and a unifocal subtype. As unifocal FMD generally leads to more severe hypertension at younger age, we hypothesized that renal hemodynamics are more disturbed in unifocal renal artery FMD as compared with multifocal FMD, leading to increased renin secretion.

Methods: We measured renal blood flow (Xenon washout method), renin secretion, and glomerular filtration rate per kidney in 101 patients with FMD (26 unifocal and 75 multifocal), all off medication and prior to balloon angioplasty. Read More

[Renal artery stenosis long time after renal denervation for resistant hypertension].

Ann Cardiol Angeiol (Paris) 2018 Jun 24;67(3):204-207. Epub 2018 May 24.

Centre d'excellence européen en hypertension artérielle Rennes-Dinard, rue Henri-Dunant, 35800 Dinard, France.

The onset of renal artery stenosis following a renal denervation is rare and occurs in the first few months after renal denervation. We report the onset of renal artery stenosis a long time after the renal denervation for resistant hypertension. This is a 74 year-old patient who stopped smoking in 1980 and who was treated for dyslipidemia with a revascularized coronary artery disease in 2011, a well-stabilized peripheral arterial disease since 2001, a stable asymptomatic carotid atheroma and a good kidney function.

Central venous (CV) catheterization is not only an invaluable diagnostic modality but also an essential therapeutic tool for the treating physician, enabling rapid and reliable intravenous administration of drugs and fluids, providing venous access to patients undergoing long-term continuous or repeated intravenous treatment such as chemotherapy, or it can be used for hemodialysis in patients suffering from acute or chronic renal disease. On the other hand, CV catheterization can lead to a wide range of life-threatening complications for the patient especially if left untreated or become late-diagnosed. In particular, arterial injuries are among the most feared complications that require early clinical suspicion for prompt diagnosis and management. Read More

A Unique Case of Renovascular Hypertension due to Fibromuscular Dysplasia in an Extra-renal Artery.

Intern Med 2018 Sep 27;57(18):2689-2694. Epub 2018 Apr 27.

Endocrinology & Diabetes Center, Yokohama Rosai Hospital, Japan.

A 33-year-old man was admitted to our hospital to undergo an evaluation to determine the cause of secondary hypertension. Computerized tomography angiography (CTA) showed bilateral multiple renal arteries with significant stenosis of the right extra-renal artery due to fibromuscular dysplasia and segmental impairment of renal perfusion. Although the plasma aldosterone concentration and plasma renin activity were within the normal ranges, percutaneous balloon dilatation of the stenotic lesion resolved his hypertension, leading to a diagnosis of renovascular hypertension caused by segmental renal ischemia due to extra-renal artery stenosis.
