ABSTRACT: Recent studies indicate that resistant hypertension (RHTN) is present in about 12% of the treated hypertensive population. However, patients with true RHTN (confirmed out of the office) have not been widely studied. We prospectively studied 204 patients (123 male, 81female, mean age 48.4 years, range 19-65 years) with truly RHTN (ambulatory daytime mean blood pressure >135/85 mm Hg). We evaluated the frequency of obstructive sleep apnea (OSA), renal artery stenosis (RAS), primary aldosteronism (PA) and other secondary forms of hypertension (HTN) and conditions. Mild, moderate and severe OSA were present in 55 (27.0%), 38 (18.6%) and 54 (26.5%) patients, respectively. Secondary forms of HTN were diagnosed in 49 patients (24.0%), the most frequent being PA (15.7%) and RAS (5.4%). Metabolic syndrome (MS) was present in 65.7% of patients. Excessive sodium excretion was evident in 33.3% of patients and depression in 36.8% patients. In patients with RHTN, OSA and MS were the most frequent conditions, frequently overlapping with each other and also with PA. Our data indicate that in the vast majority of patients with truly RHTN, at least one of three co-morbidities-OSA, MS and PA-is present. Other conditions, even though less frequent, should also be taken into the consideration.Journal of Human Hypertension advance online publication, 23 May 2013; doi:10.1038/jhh.2013.32.

ABSTRACT: We are presenting clinical characteristics, management and follow-up of five consecutive patients with renal artery aneurysm. Renal artery aneurysms are relatively uncommon, they rarely give rise to clinical manifestations and they are usually found incidentally. However with the introduction of Doppler ultrasound, computed tomography (CT) and magnetic resonance (MR) imaging, the diagnosis of renal artery aneurysms became more frequent.

ABSTRACT: Arteriovenous fistulas of the kidney are rare. They may be acquired, idiopathic or arise in congenital arteriovenous malformations. There are only few reports in the current literature describing the successful embolisation of idiopathic arteriovenous fistulas. We report a 47-year-old hypertensive female patient with a successfully embolised arteriovenous fistula. Diagnosis was made on the basis of colour duplex Doppler examination and this method enabled further successful embolisation of the fistula.

ABSTRACT: In contrast to those for coronary restenosis, the data regarding the risk factors for renal restenosis are limited.
To evaluate potential humoral risk factors for restenosis after percutaneous transluminal renal angioplasty (PTRA).
We studied 27 patients aged 54+/-10 years with atherosclerotic renal artery stenosis in a 1-year prospective follow-up. Restenosis (confirmed by angiography) occurred in eight patients 1-6 months after PTRA. We detected no Doppler ultrasound evidence of restenosis in 19 patients throughout 1 year. Blood studies were done before PTRA for all patients, at the time of diagnosis of restenosis and, for those without restenosis, after 1 year. including determinations of fibrinogen, lipids, platelets and leukocytes.
The mean level of fibrinogen in patients who experienced restenosis was higher than that in those who did not (450+/-150 mg% versus 337+/-57 mg%, P < 0.01) and remained unchanged for both groups during follow-up. The other parameters did not differ between the groups before PTRA and did not change over time, with the exception of platelet count in patients who did not experience restenosis, which had decreased from 253+/-93G/l to 200+/-63G/l (P < 0.01) 1 year after PTRA. The logistic multiple regression analysis disclosed that an increment of fibrinogen level by 100 mg% was linked with an odds ratio for restenosis of 3.2 (95% confidence interval 1.1-9.8).
Restenosis was associated with higher than normal levels of fibrinogen before PTRA. A high plasma fibrinogen level might play a role in the development of restenosis after PTRA.

ABSTRACT: The aim of this study was to evaluate the effect of renal artery stenosis (RAS) correction in hypertensive patients on 24 h SBP, 24 h DBP, creatinine clearance (GFR), urinary albumin excretion (UAE) and LV morphology and mass (LVMI). A total of 61 hypertensive patients with RAS undergoing PTRA and/or surgical treatment entered the prospective study. The final analysis was done in 44 patients (age range 45.8 +/- 16.2 years) with RAS (atherosclerosis (ASC) 31 patients, fibromuscular dysplasia (FMD) 12 patients, arteritis 1 patient) who underwent PTRA (34 patients) or surgical treatment (10 patients) and presented no Doppler signs of restenosis (or a new stenosis) during 1-year observation. The pre-interventional assessment repeated after 6 and 12 months included ABPM, GFR, UAE and echocardiography. The results were analysed in the combined group (CG) and in according aetiology. 24 h SBP and 24 h DBP decreased in all groups 6 months post-intervention and did not change further. Cure of HT was observed in 35% and 29% of ASC patients at 6 and 12 months respectively; and in 58% of FMD patients. Failure rate at 12 months was 48% in ASC against 25% in FMD. The mean GFR in CG was higher 12 months after intervention. The increase in GFR was noted in 45% of patients, the decrease in 25% of patients at 12 months. Normal values of UAE were found in 71% of patients, pre- and post-intervention alike. Mean LVMI and number of patients with LVH in CG decreased already during the initial 6 months post-intervention and did not change further. In conclusion, correction of RAS leads to cure of or improved control of hypertension in the majority of the patients with FMD, but in the ASC group in about half of cases no BP cure or improvement was seen. The renal function was improved or stable in two-thirds of patients after revascularization. Successful renal revascularization was followed by regression of LVH, which was evident within 6 months post-intervention.

ABSTRACT: Subclavian steal syndrome (SSS) appears when the origin of the subclavian artery (SA) is occluded or stenosed. Introduction of transcranial Doppler sonography (TCD) provided an opportunity to evaluate parameters of the blood flow in the vertebral (VA) and basilar artery (BA). Measurements of blood flow velocities performed at rest and after the brachial hyperemia test allow one to classify hemodynamic types of SSS. The aim of the study was to categorize types of steal and to compare the differences of flow patterns before and after percutaneous transluminal SA balloon angioplasty (SA-PTA). Fourty-eight patients with angiographically confirmed SSS (aged from 27 to 68 years, mean 53; 2/1 f/m ratio) were examined with 2 MHz range-gated, pulsed transcranial Doppler device (TC 2-64B EME). Both VA and BA were evaluated by the transoccipital approach at rest and during the brachial hyperemia. In 5 cases (10.4%) permanent reversal blood flow in the BA was observed (complete basilar steal). In flow in the BA blood flow was in the normal direction at rest and altered (reversed or decreased) when induced with brachial hyperemia test (transient basilar steal). In the next 14 patients (29.2%) permanently reversed VA blood flow was observed with only a slight or no alterations of the BA flow after the hyperemia test (complete vertebral steal). In the last 19 cases (39.6%) alterations of the VA blood flow without changes in BA flow were observed (latent vertebral steal). Between 1991 and 1994 twenty seven symptomatic patients with different hemodynamic types of SSS were treated with SA-PTA. TCD evaluation of VA's and BA using the hyperemia test was performed before, 3 to 7 days and 3 months after morphologically and hemodynamically successful subclavian artery balloon PTA. Normal results of vertebrobasilar examinations were obtained in 26 cases after this procedure. In one case the latent vertebral steal was detected. The 28 months mean follow-up revealed no significant changes in TCD flow patterns recorded from VA's and BA. After collecting data of about 60 patients with SSS we examined with TCD we conclude that: in patients with a hemodynamically significant SA stenosis the presence of reversed ipsilateral VA blood flow (a radiologic steal) its not a good determinant of either the presence or type of presenting symptoms and after successful PTA or recanalisation and PTA of SA in almost all cases we examined close to normal TCD recordings in BA and VA.

ABSTRACT: The aim of the study was to investigate endothelin-1 (ET-1) and neuropeptide Y (NPY) plasma concentrations in renal venous blood of hypertensive patients with unilateral renal artery stenosis (URAS). The study was performed in 22 patients with URAS and 18 patients diagnosed as essentially hypertensive. In each subject renal arteriography and renal vein catheterisation was performed. Blood samples for ET-1, NPY and plasma renin activity (PRA) were withdrawn from renal veins and vena cava inferior, and for ET-1 and NPY from the aorta. Patients with URAS were divided in two subgroups according to the renal vein renin ratio. Both in nine patients with URAS and ratio > 1.5 and in 13 patients with URAS and ratio < 1.5, ET-1 and NPY plasma concentrations evaluated in renal venous blood of the ischaemic kidney were not different from those assessed in the contralateral side, in vena cava inferior and in the aorta. In essential hypertension, the mean ET-1 and NPY plasma concentrations of both renal veins were not different from the ET-1 and NPY plasma values assessed in renal vein of stenosed and contralateral side, vena cava and aorta of patients with URAS with and without activation of the renin system. Our study indicates that chronic ischaemia does not affect ET-1 and NPY plasma concentrations in renal venous blood of hypertensive URAS patients both with and without activation of the renin system.
