Background: Pulmonary embolism (PE) is an acute cardiovascular syndrome characterized by high incidence and mortality. The therapy of this condition is based on anticoagulation and hemodynamic support, but in case of high-risk mortality, the European Society of Cardiology (ESC) guidelines recommend systemic thrombolytic therapy and surgical embolectomy if thrombolysis is contraindicated or has failed; nowadays several percutaneous catheter-directed treatments for local thrombolysis or mechanical embolectomy are available, but they have IIa class of recommendation, because of lack of robust scientific evidence favoring their use.
Case Description: We described a case of high-risk PE treated with a novel percutaneous system for mechanical embolectomy, which consists of a large aspiration catheter that was advanced in the pulmonary artery, capturing and removing a vast thrombus, of 15 centimeters in length. This therapeutic strategy avoided the risk of hemorrhagic complications related to systemic thrombolysis, exiting in the achievement of fast patient hemodynamic stabilization and symptoms resolution, without complications. Computed tomography (CT) pulmonary angiography after 10 days from the intervention revealed the complete resolution of pulmonary artery filling defects, and the patient was discharged asymptomatic.
Conclusions: Percutaneous catheter-directed treatments represent an effective alternative therapy for PE, but further studies are needed to demonstrate safety and superiority over the actually recommended therapy.

Pulmonary embolism (PE) is a life-threatening medical condition caused by the thrombotic occlusion of one or more branches of the lung vasculature, which represents the third most common cause of cardiovascular mortality after myocardial infarction and stroke. PE treatment requires a tailored approach based on accurate risk stratification and personalized treatment decision-making. Anticoagulation is the cornerstone of PE management, yet patients at higher clinical risk may require more rapid reperfusion therapies.

Background: Percutaneous mechanical aspiration thrombectomy is increasingly being employed as a less invasive alternative for managing right heart masses, including clot in transit.
Aims: We aimed to analyze trends in the use of catheter-directed aspiration (CDA) for right heart masses. Additionally, we analyzed in-hospital outcomes of percutaneous versus surgical approaches for patients with CIT and PE.

Pulmonary embolism (PE) is the third most frequent cause of acute cardiovascular presentation after myocardial infarction and stroke. The treatment approach for PE consists of hemodynamic and respiratory support, anticoagulation, reperfusion treatment, and vena cava filters. Reperfusion treatment consists of systemic thrombolysis (recombinant tissue-type plasminogen activator, streptokinase, and urokinase); percutaneous catheter-directed therapy (CDT); and surgical embolectomy.

The management of hepatocellular carcinoma (HCC) is undergoing transformational changes due to the emergence of various novel immunotherapies and their combination with image-guided locoregional therapies. In this setting, immunotherapy is expected to become one of the standards of care in both neoadjuvant and adjuvant settings across all disease stages of HCC. Currently, more than 50 ongoing prospective clinical trials are investigating various end points for the combination of immunotherapy with both percutaneous and catheter-directed therapies.

Article Synopsis
- Phlegmasia cerulea dolens (PCD) is a serious condition caused by massive deep vein thrombosis that can threaten both life and limbs, often requiring urgent treatment options such as endovascular therapy or surgical embolectomy in specific cases.
- A patient case illustrated simultaneous PCD with acute limb ischemia, showing symptoms like abdominal pain, cyanosis, and motor deficits, leading to a successful combined surgical embolectomy to resolve the issues.
- This report emphasizes that there are no formal guidelines for treating PCD and stresses the necessity for personalized treatment strategies and comprehensive care access.
