    MANUFACTURERS REF# (B)(4). SUMMARY OF INVESTIGATIONAL FINDINGS: A 71-YEAR OLD FEMALE WITH A TYPE B THORACIC AORTIC DISSECTION UNDERWENT A TEVAR (THORACIC ENDOVASCULAR AORTIC REPAIR) WITH A ZDEG (COMPLAINT DEVICE) AND A ZDES DEVICE. ON FOLLOW UP CT ON 21JUL2021 A LEAK WAS NOTICED. PER ADDITIONAL INFORMATION REQUESTED, THE PHYSICIAN IS INSISTENT IT IS A TEAR RATHER THAN A TYPE 2 OR 3 ENDOLEAK DUE TO THE LOCATION OF THE LEAK. IT IS REPORTED THAT THE PATIENT ANATOMY WAS WITH MINIMAL TO NO CALCIFICATION AND VESSEL TORTUOSITY. FURTHERMORE, IT IS NOTED THAT "LIKELY PLANNING FOR IMPLANTING AN ADDITIONAL GRAFT, BUT HAS NOT HAPPENED YET". BASED ON THIS FINDING "FOCAL AREA OF FALSE LUMEN PERFUSION IS ADJACENT TO THE PROXIMAL ZDES STENT JUST DISTAL TO THE ZDEG GRAFT EDGE" IN THE IMAGING REVIEW A REQUEST TO THE PHYSICIAN WAS PLACED, REQUESTING WHETHER THE ENTRY TEAR WAS PRE-EXISTING OR CONSIDERED DEVICE RELATED AND THE PHYSICIAN INDICATED THAT IT WAS RELATED TO THE DEVICE. REVIEW OF DEVICE HISTORY RECORD GAVE NO INDICATION OF THE DEVICE BEING PRODUCED OUTSIDE OF SPECIFICATIONS. AN IMAGING REVIEW OF THE PROVIDED IMAGES IS PERFORMED, THE IMAGING REVIEW OF THE REPORTED EVENT OF FABRIC TEAR IS NOT CONFIRMED. THE FOLLOWING IS THE IMAGING EXPERTS FINDINGS: "FOCAL AREA OF FALSE LUMEN PERFUSION IS ADJACENT TO THE PROXIMAL ZDES STENT JUST DISTAL TO THE ZDEG GRAFT EDGE. THE CONTRAST IN THE FALSE LUMEN DOES NOT APPEAR TO COMMUNICATE WITH THE FABRIC OF THE ZDEG GRAFT BUT, RATHER, APPEARS JUST DISTAL TO THE GRAFT EDGE. THIS IS LIKELY LEAKING ACROSS THE ZDES STENT INTO THE FALSE LUMEN FROM A RE-ENTRY TEAR HERE OR RIGHT AT THE DISTAL EDGE OF THE ZDEG GRAFT. BECAUSE THIS IS THE ONLY POSTOP STUDY, IT IS DIFFICULT TO DETERMINE IF THIS IS A NEW OR PRE-EXISTING RE-ENTRY TEAR." AND "INCIDENTALLY, THE PROXIMAL NECK DIAMETERS ON PREOP IMAGING ARE OUTSIDE THE IFU FOR THIS DEVICE AS THERE IS SIGNIFICANT AORTIC DILATION AT LESS THAN 25 MM LENGTH FROM THE LCCA. THE PROXIMAL ZDEG GRAFT IS POSITIONED AT THE LSA WITH ONLY 9 MM OF PROXIMAL SEAL LENGTH. NO PROXIMAL ENDOLEAK IS SEEN, HOWEVER" BASED ON THE PROVIDED INFORMATION AND THE IMAGING REVIEW IT HAS NOT BEEN POSSIBLE TO ESTABLISH A CAUSE FOR THE EVENT. COOK WILL REOPEN THE INVESTIGATION IF FURTHER INFORMATION OR IMAGES IS RECEIVED. COOK MEDICAL WILL CONTINUE TO MONITOR FOR SIMILAR EVENTS. THIS REPORT IS REQUIRED BY THE FDA UNDER 21CFR PART 803. THIS REPORT IS BASED ON UNCONFIRMED INFORMATION SUBMITTED BY OTHERS. NEITHER THE SUBMISSION OF THIS REPORT NOR ANY STATEMENT MADE IN IT IS INTENDED TO BE AN ADMISSION THAT ANY COOK DEVICE IS DEFECTIVE OR MALFUNCTIONED; THAT A DEATH OR SERIOUS INJURY OCCURRED; OR THAT ANY COOK DEVICE CAUSED OR CONTRIBUTED TO; OR IS LIKELY TO CAUSE OR CONTRIBUTE TO A DEATH OR SERIOUS INJURY IF A MALFUNCTION OCCURRED.
