RESUMEN
PURPOSE: To demonstrate the technical aspects of the novel Penumbra Indigo Lightning Flash System (Penumbra, Inc.) for mechanical thrombectomy of pulmonary embolism (PE). TECHNIQUE: The novel Penumbra Lightning Flash catheter is a 16 French (F) sheath-compatible device designed for advanced thrombectomy, especially in the pulmonary arteries. This device has large thrombus burden removal capacity; however, technical nuances are necessary to accomplish more with efficacy pulmonary embolism management. Access sites, pulmonary arteries catheterization technique, thrombectomy device navigation and mechanism of action are described thoroughly. CONCLUSION: Penumbra Indigo Lightning Flash system for mechanical thrombectomy as other catheter-directed treatments (CDTs) represents a major advance in contemporary PE management. With favorable safety profile and efficacy, CDTs have become an integral component of the multidisciplinary approach to PE care. CLINICAL IMPACT: The article highlights the Penumbra Indigo Lightning Flash System as a significant advancement in mechanical thrombectomy for pulmonary embolism (PE). By detailing technical aspects and procedural nuances, it supports clinicians for improvement in endovascular PE management. The system's integration into multidisciplinary care represents a major step forward, providing an effective alternative to traditional therapies, particularly for high-risk PE patients. This innovation promises to enhance patient outcomes in contemporary PE management.
