[Heart failure following lumbar surgery].

High-output heart failure may be caused by an arteriovenous fistula. A case is reported of an arteriovenous fistula following discectomy.

Do catecholamines influence the level of plasma leptin in patients with phaeochromocytoma?

The relationship between plasma leptin and catecholamine concentrations during chronic and acute catecholamine excess is studied. Patients with phaeochromocytoma, divided according to gender, were examined under basal conditions (n = 18) and at selected time-points during surgical removal of the tumour (n = 12). Appropriate controls were used (n = 23) for the basal study.

Effects of the correction of renal artery stenosis on blood pressure, renal function and left ventricular morphology.

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.

Plasma fibrinogen as a risk factor for restenosis after percutaneous transluminal renal angioplasty in patients with atherosclerotic renal artery stenosis.

Background: In contrast to those for coronary restenosis, the data regarding the risk factors for renal restenosis are limited.

Objective: To evaluate potential humoral risk factors for restenosis after percutaneous transluminal renal angioplasty (PTRA).

Methods: We studied 27 patients aged 54+/-10 years with atherosclerotic renal artery stenosis in a 1-year prospective follow-up.
