MAUDE report 8947762 ↗InjuryApr 3, 2019Difficult to Remove; Detachment of Device or Device Component; Migration; Difficult to Remove; Detachment of Device or Device Component; Migration
IT WAS REPORTED THAT COIL EMBOLIZATION WAS ATTEMPTED ON THE GASTRODUODENAL ARTERY (GDA) TO PREPARE FOR Y90 TREATMENT USING THE LEFT HEPATIC ARTERY. WHILE ADVANCING THE COIL THROUGH THE CATHETER, THE CATHETER POPPED OUT OF THE GDA AND INTO THE RIGHT HEPATIC ARTERY. THE COIL WAS REMOVED PRIOR TO AN ATTEMPT TO REPOSITION THE CATHETER, AND THE CATHETER WAS FLUSHED UNDER FLUOROSCOPY, AT WHICH TIME THE IMPLANT COIL COULD BE SEEN EXITING OUT OF THE CATHETER INTO THE PROPER RIGHT HEPATIC ARTERY. DURING AN ATTEMPT TO REMOVE THE COIL WITH A GOOSENECK SNARE, THE COIL MOVED FURTHER DOWNSTREAM AND OCCLUDED A BRANCH OF THE RIGHT HEPATIC ARTERY. SEVERAL MORE ATTEMPTS WERE MADE TO RETRIEVE THE COIL; HOWEVER, THEY WERE UNSUCCESSFUL AND THE PROCEDURE WAS FINISHED. THE PHYSICIAN COMMENTED THAT THE OCCLUDED VESSEL WILL NOT HAVE AN IMMEDIATE IMPACT ON THE PATIENT'S TREATMENT PLAN, AS THE MOST SIGNIFICANT DISEASE IS IN THE LEFT LOBE. THE PATIENT HAS METASTATIC DISEASE THROUGHOUT THE LIVER, HOWEVER, AND THE AREA OF THE LIVER WHICH WAS FED BY THE ARTERY IN WHICH THE COIL SETTLED HAS A SIGNIFICANT TUMOR. THE TUMOR WILL FIND BLOOD SUPPLY FROM OTHER COLLATERAL BRANCHES AND THOSE WILL REVASCULARIZE THE AREA.
