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.

Percutaneous transhepatic biliary drainage for biliary obstruction in perihilar cholangiocarcinoma: a 10-year analysis of safety and outcomes using the CCI index.

Purpose: To evaluate percutaneous transhepatic biliary drainage (PTBD) safety and efficacy in patients with perihilar cholangiocarcinoma (PCCA).

Methods: This retrospective observational study included patients with PCCA and obstructive cholestasis referred for a PTBD in our institution between 2010 and 2020. Technical and clinical success rates and major complication and mortality rates one month after PTBD were used as main variables.
