Acute Massive and Submassive Pulmonary Embolism: Preliminary Validation of Aspiration Mechanical Thrombectomy in Patients with Contraindications to Thrombolysis.

Purpose: 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.

Materials And Methods: Eighteen patients presenting massive (8/18) or submassive (10/18) PE were prospectively enrolled between October 2016 and November 2017. All the patients enrolled had contraindications to thrombolysis (haemorrhagic stroke n = 1, ischaemic stroke in the preceding 6 months n = 7, central nervous system damage or neoplasms n = 1, recent major trauma/surgery/head injury in the preceding 3 weeks n = 5, gastrointestinal bleeding within the last month n = 4).

Microwave ablation of malignant renal tumours: intermediate-term results and usefulness of RENAL and mRENAL scores for predicting outcomes and complications.

The aim of this study was to evaluate intermediate-term results after microwave ablation (MWA) of renal tumours and determine the association of RENAL and modified RENAL (mRENAL) scores with oncological outcomes and complications. In May 2008-September 2014, 58 patients affected by early-stage RCC (renal cell carcinoma; T1a or T1b) were judged unsuitable for surgery and treated with percutaneous MWA. Follow-up was performed with contrast-enhanced computed tomography at 1, 3, 6, 12 and 24 months after the procedure.
