BACKGROUND: The 1-year restenosis rate after standard balloon angioplasty (BA) of long lesions in below-the-knee arteries may be as high as 70%. Our aim was to investigate the efficacy and safety of paclitaxel drug-eluting balloon (DEB) for treatment of below the knee lesions in end stage renal disease patients (ESRD) with critical limb ischemia (CLI). METHODS: Our study is a retrospective, single-center study. Inclusion criteria were ESRD, critical limb ischemia (Rutherford class 4 or higher) and significant stenosis or occlusion of at least 1 below-the-knee vessel...

Chronic mesenteric ischaemia (CMI) is a rare disorder caused by severe stenosis of the mesenteric arterial supply that results in post prandial pain and weight loss. Treatment options are surgical or endovascular. Surgical bypass can be performed in an antegrade fashion from the supracoeliac abdominal aorta or the distal descending thoracic aorta or in a retrograde fashion from the infra-renal aorta or the common iliac artery. However in some patients with disease of the descending thoracic aorta (DTA) or the abdominal aorta (AA) another site for the proximal anastomosis needs to be found...

Objective Percutaneous transluminal renal artery angioplasty (PTRA) has been recommended for the treatment of renovascular resistant hypertension. However, large randomized trials have reported that PTRA did not improve the outcomes compared with optimal medical therapy in patients with renal artery stenosis (RAS). It is important to identify patients with renovascular hypertension who are likely to respond to PTRA. We herein examined whether or not the plasma renin activity (PRA) could predict the improvement in resistant hypertension after PTRA for RAS...

BACKGROUND: Transapical approach (TA) is an established access alternative to the transfemoral technique in patients undergoing transcatheter aortic valve replacement (TAVR) for treatment of symptomatic aortic valve stenosis. The impact of prior coronary artery bypass grafting (CABG) on clinical outcomes in patients undergoing TA-TAVR is not well defined. METHODS: A single center retrospective cohort analysis of 126 patients (male 41%, mean age 85.8 ± 6.1 years) who underwent TA balloon expandable TAVR (Edwards SAPIEN, SAPIEN XT or SAPIEN 3) was performed...

We performed stent placement under intravascular ultrasound (IVUS), without the use of contrast medium, in a male patient in his 70s who had vertebral artery origin stenosis and decreased renal function. Satisfactory dilatation was achieved without complications, and the patient remained asymptomatic at 2 years of follow-up. We now report the details of this procedure. Stent placement under IVUS guidance may be useful in patients in whom contrast medium is contraindicated.

Endovascular revascularization as treatment of atherosclerotic renal-artery stenosis (aRAS) is controversial since 3 large and multicentric randomised trials (CORAL, ASTRAL, STAR) failed to prove the superiority of percutaneous transluminal renal-artery stenting (PTRAS) over medical treatment only (MT). However, considering the multiple bias of these trials, among which questionable inclusion criterias, these results must be extrapolated in clinical practice with caution. New pathophysiological data have been helping to understand why restoring blood flow does not necessarily lead to kidney function improvement...

BACKGROUND: Renal artery stenosis is a common cause of secondary hypertension refractory to medical therapy. Percutaneous angioplasty along with metallic stent placement has been described as an effective treatment for revascularization of the renal artery. CASE REPORT: A 54-year-old woman affected by paranoid schizophrenia with a history of hypertension and chronic renal failure due to renal artery occlusion was treated by endovascular recanalization and stent placement that resulted in improvement of renal function and control of hypertension...

Atherosclerotic Renal Artery Stenosis is a form or peripheral arterial disease that tends to affect older subjects with hyperlipidemia, history of tobacco use, and who have other coexistent forms of vascular insufficiency. An abdominal bruit on physical exam can be a helpful clue. Slowly progressive, it can lead to critical narrowing of the renal arteries which creates a cascade of events such as renin-angiotensin-aldosterone activation (RAAS), hypertension, acute pulmonary edema, and renal fibrosis. The hypertension is considered a secondary form and can even be resistant to multiple antihypertensives...

This study included 126 hypertensive patients with renal artery stenosis (mean age, 63 years; 22.2% fibromuscular dysplasia [FMD]) and investigated the effects of percutaneous transluminal renal angioplasty on office and home blood pressure (BP), and BP variability estimates derived from home BP, both at baseline and up to 12 months after angioplasty. Home BP was measured for 7 consecutive days, and the threshold defining uncontrolled home BP was ≥135/85 mm Hg. In both the FMD and atherosclerotic stenosis (ARAS) groups, office and home BP decreased significantly after angioplasty (all P<0...

Renal artery stenosis (RAS) is the most common vascular complication following renal transplantation. Percutaneous endovascular transluminal angioplasty with stenting is the treatment of choice for clinically significant RAS. We present a case describing a novel combined trans-renal parenchyma and trans-femoral approach to repairing a disrupted transplant renal artery stent. Our patient's allograft RAS was initially managed by standard percutaneous approach, but during follow-up the stent became disrupted and crushed causing partial occlusion of the renal artery...

Constriction of the renal artery and controlled reduction of renal perfusion pressure is followed by a prompt increase in systemic renin activity and a concomitant rise in blood pressure in trained, unanesthetized dogs. The elevated blood pressure induced by the renal artery stenosis can be prevented by prior treatment with the nonapeptide Pyr-Trp-Pro-Arg-Pro-Gln-Ile-Pro-Pro, which blocks conversion of angiotensin I to angiotensin II. Further, the nonapeptide can restore systemic pressure to normal in the early phase of renovascular hypertension...

OBJECTIVES: The aim of this study was to assess the relationship of the extent of atherosclerosis on coronary computed tomographic angiography to the extent of secondhand tobacco smoke (SHTS) exposure in asymptomatic never smokers. BACKGROUND: A dose-related association between SHTS and coronary artery calcium has been reported, but the total extent of atherosclerosis has not been investigated. METHODS: Two hundred sixty-eight never smokers, ages 40 to 80 years, completed a questionnaire assessing risk factors and extent of lifetime SHTS exposure, providing a total SHTS exposure score...

Fibromuscular dysplasia (FMD) is a non-inflammatory, non-atherosclerotic vasculopathy that can lead to arterial stenosis, occlusion, aneurysms, and dissection. FMD of the renal arteries can lead to renovascular hypertension. Percutaneous angioplasty of the renal arteries (PTRA) can lead to normalization of blood pressure in 45% of patients with renal artery stenosis caused by FMD, particularly in younger patients and patients with a short history of hypertension. A considerable number of the patients with renovascular FMD also have cervical FMD, which can lead to ischaemic or haemorrhagic stroke...

Arterial hypertension (AH) is a major risk factor for chronic kidney disease (CKD). However, whether AH maintains this role in the development of CKD in elderly patients with aortic stenosis (AS) or whether transaortic gradient influences CKD remains unclear. Consecutive hospitalized patients were prospectively recruited to evaluate the relationship between AS and CKD. In all patients, transthoracic 2-dimensional echocardiography was performed to evaluate AS; renal function was evaluated using the Chronic Kidney Disease Epidemiology Collaboration formula...

The aim of this study was to evaluate outcomes and feasibility of carotid artery stenting versus carotid endarterectomy, both procedures performed in the same patient. Forty-five subjects (33 males, 70 ± 7 years) underwent carotid endarterectomy or carotid artery stenting, the counter procedure on the contralateral carotid performed after a variable period. We evaluated the post-procedural percentage of carotid stenosis at 30, 180 days and one-year follow-up, and the occurrence of acute myocardial infarction, New York Heart Association class progression, stroke, death, cardiovascular death, angina, transient ischemic attack and renal failure...
