Cone beam CT pulmonary angiography in balloon pulmonary angioplasty for chronic thromboembolic pulmonary hypertension during the program initiation period.

Aim: Cone beam CT pulmonary angiography (CBCT-PA) has proven to be a valuable technique during balloon pulmonary angioplasty (BPA) for chronic thromboembolic pulmonary hypertension (CTEPH) in established centres. This study aimed to demonstrate the safety and efficacy of CBCT-PA-guided BPA for CTEPH during the initial period of a BPA program. CBCT-PA improves procedural accuracy by visualising distal thromboembolic lesions and providing real-time guidance, which is critical during program initiation.

Perivascular and parenchymal brain fluid diffusivity in patients with a recent small subcortical infarct.

Purpose: Fluid exchanges between perivascular spaces (PVS) and interstitium may contribute to the pathophysiology of small vessel disease (SVD). We aimed to analyze water diffusivity measures and their relationship with PVS and other SVD imaging markers.

Methods: We enrolled 50 consecutive patients with a recent small subcortical infarct.

Imaging of chronic thromboembolic pulmonary hypertension before, during and after balloon pulmonary angioplasty.

Balloon pulmonary angioplasty (BPA) has recently been elevated as a class I recommendation for the treatment of inoperable or residual chronic thromboembolic pulmonary hypertension (CTEPH). Proper patient selection, procedural safety, and post-procedural evaluation are crucial in the management of these patients, with imaging work-up playing a pivotal role. Understanding the diagnostic and therapeutic imaging algorithms of CTEPH, the imaging features of patients amenable to BPA, all imaging findings observed during and immediately after the procedure and the changes observed during the follow-up is crucial for all interventional radiologists involved in the care of patients with CTEPH.

Inferior Vena Cava Filters: Adherence to Clinical Practice Guidelines Recommendations, Retrieval Rates, and Filter Complications in a Tertiary Hospital.

The present study evaluated the adherence to guideline recommendations regarding the indication for inferior vena cava filter (IVCF) placement, retrieval rates, complications, thrombotic recurrences, and mortality. Patients in whom an IVCF was placed between 2015 and 2020 in a tertiary hospital were retrospectively included. We considered absolute indication of IVCF placement if all the guidelines evaluated agreed on the indication, relative indication if only some guidelines recommended it and without indication if none of the evaluated guidelines recommended it.
