Pulmonary thromboembolism in coronavirus disease 2019 patients undergoing thromboprophylaxis.

We aimed to investigate the prevalence of pulmonary thromboembolism (PTE) and its association with clinical variables in a cohort of hospitalized coronavirus disease 2019 (COVID-19) patients receiving low-molecular-weight heparin (LMWH) at prophylactic dosage.In this retrospective observational study we included COVID-19 patients receiving prophylactic LMWH from admission but still referred for lower-limbs venous Doppler ultrasound (LL-US) and computed tomography pulmonary angiography (CTPA) for clinical PTE suspicion. A dedicated radiologist reviewed CTPA images to assess PTE presence/extension.

Appropriateness of Duplex ultrasound assessment on venous system of the legs: a two-month preliminary analysis.

Aim: The goal of this study is to evaluate the appropriateness to prescribe venous ultrasound of lower limbs.

Material Of Study: Over a two months period, 1005 Duplex scans were performed by our Vascular Surgery Unit; out of the total, 225 exams were conducted on venous system of lower limbs. We retrospectively analyzed appropriateness of prescription (according to Lombardy District indications), urgency of prescription, time-lapse between application for the exams and its execution, positive or negative results, National Health System's sustained cost.

A 16-year experience of carotid artery stenting for carotid artery stenosis.

Aim: We report our experience of carotid artery stenting (CAS) for the endovascular treatment of significant carotid stenosis over 16 years.

Materials And Methods: Data of all consecutive patients who came for a significant carotid artery stenosis from January 1st 1999 to August 31st 2015 were retrospectively collected and analyzed. Primary outcomes were the occurrence of death and major cerebrovascular events (MCE) both at 30-day and at long-term.

Varicose veins: new trends in treatment in a Vascular Surgery Unit.

Aim: Less invasive techniques such as foam sclerotherapy, endovenous laser or radiofrequency ablation have recently been introduced as a valid alternative to surgery for the treatment of varicose veins (VVs). We retrospectively reviewed our experience in the treatment of VVs with particular attention to how our therapeutic approach has changed over the last years.

Material Of Study: Data of all patients consecutively treated from September 1st 2013 to July 31st 2015 for both primitive and recurrent VVs were retrospectively collected and analyzed.
