This case demonstrates that large-bore percutaneous suction thrombectomy using the Inari FlowTriever system can safely and effectively treat fat embolism in-transit and relieve associated right heart strain.
May support percutaneous thrombectomy feasibility in fat embolism in-transit; hypothesis-generating and requires prospective validation before wider use.
We report the case of a previously independent 82-year-old female who experienced acute hemodynamic and respiratory deterioration requiring inotropic support due to a fat embolism during revision hip arthroplasty. Computed tomography pulmonary angiography demonstrated fat embolism, and transesophageal echocardiogram showed evidence of right ventricle strain and fat embolism in-transit in the right heart, as well as a moderate patent foramen ovale. Under transesophageal echocardiogram and intravascular ultrasound guidance, the Inari FlowTriever thrombectomy device was used successfully to retrieve the fat embolism with immediate hemodynamic improvement, no complications, and uneventful recovery.

Saricilar et al. (2024) conducted a case report in Fat embolism in-transit with right heart strain and shock (n=1). Percutaneous large-bore aspiration thrombectomy (Inari FlowTriever system) was evaluated. Percutaneous large-bore aspiration thrombectomy successfully retrieved a fat embolism in-transit, leading to immediate hemodynamic improvement, weaning of inotropic support, and uneventful recovery.
