Ct angiography evaluation of the renal vascular pathologies: a pictorial review

The emergence of CT angiography (CTA) has a groundbreaking impact on the evaluation of renal vessels and is gradually replacing the conventional catheter angiography as the standard imaging procedure. In this review, we aimed to describe the renal CTA technique and imaging findings of several renal arterial (i.e. atherosclerosis, fibromuscular dysplasia, aneurysms of the renal arteries, dissection, vasculitidis, follow-up of patients with renal arterial stent) and venous (i.e. nut-cracker syndrome, pelvic congestion syndrome) pathologies

Cholesterol efflux promoting function of high-density lipoproteins in calcific aortic valve stenosis

Background and aims: Cholesterol efflux capacity is a functional property of high-density lipoproteins (HDL) reflecting the efficiency of the atheroprotective reverse cholesterol transport process in humans. Its relationship with calcific aortic valve stenosis (CAVS) has not been fully assessed yet. Methods: We evaluated HDL-CEC in a patient population with varying degrees of aortic valvular calcific disease, assessed using echocardiography and cardiac computed tomography. Measurement of biomarkers that reflect osteogenic and tissue remodeling, along with dietary and gut microbiota-derived metabolites were performed. Results: Patients with moderate-severe CAVS had significantly lower HDL-CEC compared to both control and aortic sclerosis subjects (mean: 6.09%, 7.32% and 7.26%, respectively). HDL-CEC displayed negative correlations with peak aortic jet velocity and aortic valve calcium score, indexes of CAVS severity (ρ = -0.298, p = 0.002 and ρ = -0.358, p = 0.005, respectively). In multivariable regression model, HDL-CEC had independent association with aortic valve calcium score (B: -0.053, SE: 0.014, p < 0.001), GFR (B: -0.034, SE: 0.012, p = 0.007), as well as with levels of total cholesterol (B: 0.018, SE: 0.005, p = 0.002). Conclusion: These results indicate an impairment of HDL-CEC in moderate-severe CAVS and may contribute to identify potential novel targets for CAVS management

Preoperative evaluation of hilar vessel anatomy with 3-D computerized tomography in living kidney donors

Objectives. Digital subtract angiography is the gold standard for anatomic assessment of renal vasculature for living renal donors. However, multidetector-row computerized tomography (MDCT) is less invasive than digital subtract angiography and provides information of kidney stones and other intra-abdominal organs. In this study, preoperative MDCT angiography results were compared with the peroperative findings to evaluate the accuracy of MDCT for the evaluation of renal anatomy

Coronary artery calcifications in hemodialysis patients and their correlation with the prevalence of erectile dysfunction

Introduction. Our aim in this study was to investigate the prevalence and correlation with coronary artery calcium scores (CACS) and erectile dysfunction (ED) among hemodialysis patients

Inoperable Isolated Cardiac Hydatid Cyst Controlled With Albendazole In An Older Adult With Dementia

Hydatid cyst, a human parasitic disease, remains a clinical problem in undeveloped and developing countries. Although liver and lungs are regular sites of infection, rarely other organs such as the heart can be involved. Herein, we report an isolated cardiac hydatid cyst in an 87-year-old man. He had a history of dementia for 5 years and no history for cardiac or pulmonary disease. He presented with exertional dyspnoea which continued up to 6 months. The diagnosis was made by echocardiography and computed tomography (CT). The patient was inoperable and was treated with albendazole 10 mg/kg for 6 months. After a 6-month follow-up, echocardiography revealed reduction in the size of the cyst. We believe this is the first documented case of cardiac hydatid cyst which regressed with only medical treatment in an older adult with dementia.WoSScopu
