The authors evaluated the effectiveness of percutaneous renal revascularization (PRR) with stenting for the treatment of atherosclerotic renal artery stenosis (ARAS) in patients with coronary artery disease and the usefulness of captopril renal scintigraphy for predicting clinical outcomes after PRR. Sixty-four consecutive patients, referred for evaluation of suspected ARAS, after coronary angiography, underwent baseline captopril renal scintigraphy followed by renal angiography. Forty-four patients (68.7%)...
Randomized trials have failed to show clinical benefit in patients with atherosclerotic renal artery stenosis who were treated with angioplasty with or without stenting. However, these studies were done in patients with a high-grade stenosis. This paper examines whether there are arguments to consider patients with low-grade stenosis for angioplasty.
We report an aneurysm degeneration of a vein graft in a previous aortorenal bypass performed five years earlier for severe right renal artery stenosis due to Takayasu arteritis. The patient was a 31-year-old woman who suffered from refractory hypertension. The autogenous bypass adopting great saphenous vein was performed from her infrarenal abdominal aorta to her right renal artery. Five years after the operation, the patient complained vague discomfort in her abdomen. Three-dimensional computed tomography ...
To investigate the factors associated with the occurrence of transplant renal artery stenosis (TRAS).
To evaluate the safety and efficacy of endovascular intervention with angioplasty and stent placement in patients with transplant renal artery stenosis.
Concurrent involvement of bilateral renal and cerebral arteries, usually incurred as stenosis, is rare in childhood-onset Takayasu arteritis (c-TA). We report the case of a 14-year-old girl, with c-TA, presenting with transient ischemic attack after endovascular revascularization for renal artery stenosis and cerebrovascular stroke after surgical revascularization for cerebral artery stenosis associated with childhood-onset moyamoya syndrome. We deem that decrease of blood pressure by endovascular revascula...
Fibromuscular dysplasia is a heterogeneous group of systemic, noninflammatory, and nonatherosclerotic diseases of the vascular wall. It is the second-most common abnormality of the renal artery. Although hypertension is the most common presenting symptom, other symptoms, such as pulsatile tinnitus, stroke, chest pain, or abdominal discomfort, may result from other affected vascular beds. Revascularization of the renal artery appears to be effective at lowering blood pressure in many patients with renal arte...
Fibromuscular dysplasia (FMD), which usually affects the renal artery, also affects the carotid, vertebral, and intracranial arteries. Previous studies have shown a high prevalence of concomitant renal artery and cervicocranial lesions in FMD patients. However, the analyzed subjects were mostly Caucasians in Western countries.
Renal artery stenosis (RAS) in isolation or in conjunction with middle aortic syndrome (MAS), are important vascular causes of childhood hypertension. Few longitudinal studies have assessed the risk of surgical or endovascular intervention, and outcomes by etiology or extent of vascular disease.
We hypothesized the inflammatory markers (IM) could be independent predictors of carotid stenosis progression (CSP) after carotid artery stenting (CAS).
Renal cell carcinoma (RCC) exhibits a natural tendency to extend from the kidney into inferior vena cava (IVC) and growing into the right atrium is a rare complication. We report a 65-year-old patient with an RCC with intravascular extension through renal vein into the IVC and right atrial combined with severe coronary artery disease. This case has not been described in the literature and there is no treatment guideline for it.
Catheter-based intravascular near-infrared spectroscopy (NIRS) detects a lipid signal from atherosclerotic plaque. The aim of this study was to describe the effect of carotid artery stenting (CAS) on the lipid signal in a carotid stenosis.
Right-sided subclavian artery stenosis is a rare cerebrovascular disease involving the upper extremities. Considering an endovascular approach for its management requires increased endovascular and catheterization skills, when compared to the left side, due to the close approximation of the right subclavian artery origin, vertebral and common carotid arteries.
True degenerative aneurysms involving the donor renal artery after kidney transplantation are rather rare. The indications for operation and optimal therapy to combat this vascular complication are still not clear. Surgical revision has been used as a potential treatment; nonetheless, it has been associated with high risk of complications. In the present study, we report on a 31-year-old woman with a true aneurysm located at transplant renal artery after transplantation that was successfully managed with st...
Resistant hypertension is defined by the inability to maintain within normal limits the blood pressure values of an individual, while he is under treatment with maximal tolerated doses of three antihypertensive agents. One of the most common types of resistant hypertension is renovascular hypertension (RVH), which is caused by the narrowing of the renal arteries, in the context of existing atherosclerotic plaques at that level. We are presenting the case of a hypertensive 56-year-old man admitted in the Cli...
Carotid artery endarterectomy (CEA) remains the most common surgical intervention for the treatment of symptomatic and asymptomatic carotid artery stenosis. Several studies have shown a lower risk of periprocedural adverse events in statin-users who undergo coronary interventions orcarotid artery stenting.
Acute renal infarction (ARI) is a rare disease with atrial fibrillation being its main cause. The possible laterality of ARI is controversial. This study aimed to evaluate the association between anatomical features of the renal arteries and ARI.
After carotid artery stenting, the procurement of information about blood flow redistribution among brain-feeding arteries and its time trend is essential to understanding a patient's physiological background and to determine their care regimen. Cerebral blood flow has been measured twice following carotid artery stenting in few previous studies, with some discrepancies in the results. The purpose of this study was to measure cerebral blood flow at multiple time points after carotid artery stenting, and to ...
Iatrogenic injuries of the renal artery include pseudoaneurysms (PSA) and pseudoaneurysms with arteriovenous fistula (PSA + AVF). They can cause hematuria, anemization and flank pain. Endovascular treatment is recommended due to its effectiveness.
To describe an endovascular technique to close a renal artery fenestration during fenestrated endograft implant for a para-renal aneurysm (p-AAA) without interfering with other visceral vessels REPORT: A 76-year-old-male with p-AAA underwent repair by a four fenestrations custom-made endograft. At the intra-procedural angiography, the right renal artery was occluded. In order to avoid a high-flow endoleak from fenestration, we performed the following technique: a 9F-steerable sheath was used to advance a 7F...
Renal artery calcium (RAC) has been linked to several cardiovascular disease (CVD) risk factors, including age, male gender, and hypertension. The purpose of this study was to determine whether anthropometric measures of obesity are associated with presence of RAC.
Low-energy shockwave (SW) therapy attenuates damage in the stenotic kidney (STK) caused by atherosclerotic renal artery stenosis (ARAS). We hypothesized that magnetic resonance elastography (MRE) would detect attenuation of fibrosis following SW in unilateral ARAS kidneys.
To describe the role of Duplex-Ultrasound Imaging (DUI) in prompt diagnosis of pseudoaneurysm (PSA) of a branch of the segmental renal artery (b-SRA) and evaluate outcomes of DUI directed percutaneous embolization.
