ABSTRACT
Introduction: Catheter directed interventions (CDIs) have evolved over the past decade in an attempt to reduce the complications of systemic thrombolysis, while providing equivalent therapeutic benefits.
Areas covered: CDIs include a wide array of catheters that incorporate ultrasound technology, the infusion of thrombolytics through multi-side hole catheters and suction thrombectomy systems. We present a contemporary review summarizing the different catheter directed interventions currently available for acute PE, their indications, technical considerations, clinical effectiveness, complication rates and long-term outcomes.
Expert opinion: For intermediate high-risk PE patients without a contraindication for thrombolysis, CDIs should be considered in patients at risk for clinical decompensation. For high risk PE patients with a major contraindication to thrombolytic therapy, suction thrombectomy can be considered in places with appropriate clinical and technical expertise.
Article Highlights
CDI have been promoted for use in both intermediate and high-risk PE in an attempt to reduce the complication rates of systemic thrombolytics.
For intermediate high-risk PE patients without a contraindication for thrombolysis, catheter thrombolysis should be considered in patients at risk for clinical decompensation.
For high risk PE patients with a major contraindication to thrombolytic therapy, suction thrombectomy can be considered in places with appropriate expertise.
Multidisciplinary teams are required to better identify the patient population that might benefit most from these invasive interventions.
