Background: Acute pulmonary embolism is recorded as one of the most common and critical medical conditions, resulting in a notable mortality rate requiring a multidisciplinary management. In this series, we address the management of massive and sub-massive pulmonary embolism utilizing catheter-based intervention, in particular the conjunction of mechanical thrombus disruption and aspiration with pharmacological thrombolysis (pharmacomechanical thrombectomy). Results: 37 patients were diagnosed with massive and sub-massive pulmonary embolism based on the clinical and radiological findings. Pre-procedural vital parameters were obtained, including oxygen saturation, pulse rate, and blood pressure. Under continuous monitoring and conscious sedation, a pulmonary angiography via right common femoral vein access was performed for pre-procedural assessment. Pharmacomechanical thrombectomy was performed using the AngioJet Ultra System (Boston Scientific). Using the power pulse option, a fibrinolytic agent was infused into the thrombus. After 5–10 min, mechanical thrombectomy is performed with a maximum 3 passes through the thrombus. This technique is performed in the main pulmonary artery and lower branch. The procedure is repeated on the other side. The maximum duration of thrombectomy is 2–3 min on each side. Procedure success was based on improvement of vital signs and not related to post-procedure angiographic findings. All patients showed immediate improvement of vital signs (blood pressure, 02 saturation, and pulse rate) with progressive improvement over the following days. There were no procedure-related complications. Conclusion: Pharmacomechanical thrombectomy is a safe and effective technique in the treatment of massive and submassive pulmonary embolism. It can be a first-line treatment even in patients without absolute contraindication to systemic thrombolysis. [ABSTRACT FROM AUTHOR]
