Event or Problem Description
A 49-year-old male with renal cell carcinoma tumor, was given a 50% survival rate over the next 90 days.The patient had deep vein thrombosis (dvt) clot which extended from the bilateral popliteal into the inferior vena cava (ivc) with tumor thrombus extending from the right renal vein.The case began with the patient in a supine position.Access was obtained without issue and the protrieve sheath was placed in the internal jugular and secured with a tegaderm.A clottriever sheath 16fr., was placed in both popliteal veins.The clottriever bold catheter was advanced into position on the right and six passes were performed with an additional four aspirations.This removed a large amount of thrombus which had extended from the femoral vein into the iliac.The physician switched to the left side and four passes were performed which also yielded a large clot haul.The physician then moved to the ivc and performed four passes and five aspirations with the clottriever xl catheter (ctxl) which removed chronic clot.A venogram was then performed which revealed thrombus still present in the ivc confluence.The physician elected to move to more aggressive pulls with the ctxl further into the iliac.The protrieve sheath was also moved from the infrarenal to the suprarenal.On the third pull, the ctxl would not pull through the protrieve sheath.Multiple troubleshooting attempts were made before the protrieve sheath began to shoulder.The protrieve sheath was re-positioned with the ctxl positioned in the iliac and an aspiration was performed.A code was called, and cardiopulmonary compressions were conducted.Pressers and tpa were also given.The protrieve was removed from the body while the ctxl remained.Life saving measures were performed for the next 26 minutes, but the patient unfortunately did not make it.The ctxl was eventually removed under extreme force.Examination of the device revealed three solid sauced-shaped tumor clots sticking out of the collection basket.
