RESUMO
PURPOSE: The purpose was to demonstrate a new arch endograft configuration to allow total endovascular aortic arch repair exclusive from transfemoral approach. TECHNIQUE: The custom-made multi-branched arch endograft (Cook Medical, Bloomington, Indiana) features 3 inner branches (IBs) for supra-aortic vessels incorporation and complete endovascular arch repair. Traditionally, the innominate and left carotid branches are anterograde IBs, requiring upper access for incorporation of these vessels, and the left subclavian branch is an upward-facing IB that can be incorporated from transfemoral access. We report a novel device configuration with only upward-facing IBs, allowing exclusive transfemoral route for total endovascular arch repair. Technical aspects, implantation technique, and limitations are described thoroughly. CONCLUSION: Herein is described an arch endograft configuration that simplifies endovascular aortic arch repair, allowing supra-aortic vessel incorporation through a transfemoral route only. This innovative design may serve as another alternative in selected patients. CLINICAL IMPACT: This innovative endograft design, with only upward-facing inner branches, simplifies the total endovascular aortic arch repair by allowing for a exclusively transfemoral approach. This may reduce procedural complexity and minimizes risks associated with multiple access points. It provides another alternative, particularly beneficial for selected high-risk patients for open repair, potentially expanding the applicability of endovascular treatments for aortic arch pathologies.
RESUMO
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.
