ReviewBalloon Pulmonary Angioplasty for Chronic Thromboembolic Pulmonary Hypertension.
Chronic thromboembolic pulmonary hypertension (CTEPH) is a potentially lethal outcome of pulmonary embolism. Balloon pulmonary angioplasty (BPA) is aimed at improving pulmonary perfusion and pulmonary hemodynamics and has gained a lot of interest recently in patients either unsuitable for or refractory to surgical pulmonary endarterectomy. This article outlines the clinical features and diagnostic criteria, imaging evaluation, current medical and surgical treatment options for CTEPH. BPA is discussed in detail, focusing on the rationale, patient selection, technical details, post-procedural care and outcomes.

Acute Massive and Submassive Pulmonary Embolism: Preliminary Validation of Aspiration Mechanical Thrombectomy in Patients with Contraindications to Thrombolysis.
The aim of this study is to assess the feasibility of aspiration mechanical thrombectomy in patients with massive and submassive pulmonary embolism (PE) and contraindications to thrombolysis. ⋯ The high technical and clinical success of the procedure employed in this study suggests that aspiration mechanical thrombectomy is a promising technique when used alone. More extensive prospective studies are needed to assess the feasibility of this treatment.

Comparative StudyPercutaneous Ablation Versus Nephrectomy for Small Renal Masses: Clinical Outcomes in a Single-Center Cohort.
To compare the outcomes of percutaneous ablation (PA) versus nephrectomy (NE) for small renal masses (SRMs) in patients with T1 renal cell carcinoma and evaluate the role of pre-procedural biopsy in the treatment of SRM. ⋯ PA is a safe alternative to NE in the treatment of SRM, with similar overall survival and decreased complication rates. Pre-procedural biopsy decreases the rate of intervention for benign tumors and should be routinely performed.

Image-Guided Thermal Ablation for Non-resectable Recurrence of Renal Cell Cancer Following Nephrectomy: Clinical Experience with Eleven Patients.
To assess the feasibility, safety and clinical outcomes of image-guided percutaneous thermal ablation as salvage therapy for local recurrence of renal cell carcinoma (RCC) in patients initially treated surgically with curative intent. ⋯ Image-guided percutaneous thermal ablation is a feasible, safe and effective for local recurrence after nephrectomy, representing a non-surgical alternative for unresectable disease.

Transarterial Radioembolization Following Chemoembolization for Unresectable Hepatocellular Carcinoma: Response Based on Apparent Diffusion Coefficient Change is an Independent Predictor for Survival.
To evaluate whether response based on contrast-enhanced magnetic resonance imaging (MRI) and apparent diffusion coefficient (ADC) change at diffusion-weighted MRI after transarterial radioembolization (TARE) can predict survival, in patients with prior transarterial chemoembolization with drug-eluting beads (DEB-TACE) for hepatocellular carcinoma (HCC). ⋯ ADCratio following TARE is an independent predictor for survival in patients who previously underwent DEB-TACE for HCC.
