• MalfunctionJun 26, 2026Device Dislodged or Dislocated

  IT WAS REPORTED THROUGH THE CLINICAL STUDY CAR THAT A WEB WAS USED FOR EMBOLIZATION OF A BASILAR TIP ANEURYSM. AN INITIAL 5 MM × 2 MM WEB SL DEVICE WAS DEPLOYED; HOWEVER, DUE TO INADEQUATE LATERAL COMPRESSION AND CONCERN FOR RECURRENCE, THE DEVICE WAS RESHEATHED AND EXCHANGED FOR A 6 MM × 2 MM WEB SL DEVICE. IT WAS REPORTED THAT FOLLOW-UP ANGIOGRAPHY DEMONSTRATED COMPLETE ANEURYSM OCCLUSION WITH MILD ENCROACHMENT (APPROXIMATELY 50%) INTO THE PARENT ARTERY AND IMPROVED DEVICE COMPRESSION. THE DEVICE WAS DETACHED WITH STABLE POSITIONING CONFIRMED ON POST-DETACHMENT IMAGING. IT WAS REPORTED THAT AT THE 7-DAY FOLLOW-UP, THE PATIENT EXHIBITED NO NEUROLOGICAL DEFICITS. THE PATIENT WAS DISCHARGED ON (B)(6) 2025 WITH A MODIFIED RANKIN SCALE SCORE OF 0. AT SIX-MONTH FOLLOW-UP ON (B)(6) 2026, MAGNETIC RESONANCE ANGIOGRAPHY DEMONSTRATED COMPLETE ANEURYSM OCCLUSION WITH PRESERVED PARENT ARTERY PATENCY AND PERSISTENT 50% STENOSIS, WITH NO EVIDENCE OF RECURRENCE, HEMORRHAGE, STENT STENOSIS, OR DEVICE MIGRATION. THE PATIENT REMAINED CLINICALLY STABLE WITH A MODIFIED RANKIN SCALE SCORE OF 0.
