A lead extraction procedure commenced to remove a right atrial (ra), a right ventricular (rv) and a left ventricular (lv) lead due to cied system/pocket infection.Spectranetics lead locking devices (llds) were inserted into each lead to provide traction.Beginning with a spectranetics 11f tightrail (long) rotating dilator sheath on the ra lead, advancement was unsuccessful.Switching to a spectranetics 11f tightrail sub-c rotating dilator sheath, progress was made to the superior vena cava (svc).Once reaching this area, the tightrail sub-c was removed, and replaced with the same 11f tightrail (long).However, the patient's blood pressure suddenly dropped.An ice catheter confirmed there was no effusion or hemothorax, the blood pressure improved over time, and the ra lead was removed without difficulty.A spectranetics glidelight laser sheath was reportedly used, but time of use is unknown.Next, the lv lead was targeted for removal.Using the tightrail sub-c, progress was made to the svc, then replaced with the same tightrail (long), which advanced to the coronary sinus (cs) os.The lv lead appeared to be stuck in the mid-lateral cs, but freed with mild traction.When the tightrail (long) was removed from the patient, sudden brisk arterial bleeding was observed, and rescue efforts began immediately.The physician manually compressed the site of bleeding at the pocket and tried to place sutures without success, resulting in 500-700 ml blood loss.Blood transfusions were administered, and vascular surgery was called in to attempt hemostasis.A large vessel injury was identified, and a limited vascular repair was performed at the pocket using sutures.However, the patient's condition precipitously declined, with blood pressure continuing to drop.Frank signs of heart failure were detected via transesophageal echocardiography (tee), and required medical support.The patient went into ventricular tachycardia (vt) and ventricular fibrillation (vf), which required multiple defibrillator attempts, and with use of medications, the heart rhythm stabilized.After the limited repair, there was a dramatic reduction in bleeding but not full resolution.Angiograms were taken, with no signs of active bleeding.Subsequent angiograms revealed the axillary artery had begun to thrombose.The patient became entirely unresponsive to further medical intervention, and suffered overwhelming disseminated intravascular coagulation (dic) and was unable to recover, resulting in death.Posthumously, a perforation of a distal, posterior branch of the axillary artery was discovered.It is likely that during the initial implant of the lv lead, it entered and exited the axillary artery and then entered the subclavian vein, where it was subsequently implanted in the cs.When the tightrail advanced down the lv lead, it opened up the axillary artery, where the lead had been present since the time of implant.This event captures the 11f tightrail (long) advancing down the lv lead when the perforation occurred, requiring intervention but resulting in death.There was no alleged malfunction of any spectranetics devices in use during the procedure.
