MAUDE Adverse Event Report: ENDOLOGIX SANTA ROSA ALTO; MAIN BODY

Model Number TV-AB2080-N

Device Problem Fluid/Blood Leak (1250)

Patient Problem Low Blood Pressure/ Hypotension (1914)

Event Date 12/19/2023

Event Type  Injury  

Event Description

The patient was initially treated for an abdominal aortic aneurysm (aaa) with the implantation of the alto abdominal aortic aneurysm stent system, two (2) ovation ix iliac limbs, and ovation prime fill polymer.During the initial implant procedure, uniform filling of the graft was noted.The physician then began wiring the contralateral gate, and after cannulating and measuring the length between the contralateral gate and the hypogastric artery, it was observed that the patient became hypotensive, possibly due to a suspected rupture.A check for a polymer leak was performed, indicating that the polymer syringe was empty.The physician then removed the autoinjector so that the polymer situation could be addressed.Epinephrine and benadryl were administered, which stabilized the patient's vital signs.The physician chose not to inflate the balloon near the sealing area to avoid disrupt the polymer, as an angiogram had already confirmed a secure seal.The main body was released using a third nested knob.The limb on one side was measured using ivus (intravascular ultrasound) and successfully implanted.The ovation ix iliac limbs were ballooned with two (2) 12x3 (non-endologix) balloons at 5 atmospheres of pressure (atm).The distal limb segments were also ballooned.A completion angiogram confirmed aneurysm exclusion.The final patient status was reported as stable.

Manufacturer Narrative

The devices involved in this event will not be returned for evaluation and remain implanted in the patient.Patient medical records and imaging studies will be requested for further evaluation by a clinical specialist.If additional information pertinent to the incident is obtained, a follow-up report will be submitted.

Manufacturer Narrative

The reported adverse event/incident was investigated in alignment with endologix operating procedures and work instructions.Where possible, it is endologix's practice to make at least three good-faith efforts to retrieve a reported adverse event/incident-related device, as well as medical records and medical imaging.An evaluation of the manufacturing record was completed.A review of the part number/lot number combination needed for device identification shows the device to have been properly manufactured and released in accordance with the device master record.The review confirms there were no manufacturing or processing non-conformities identified that would contribute to the reported adverse event/incident.The device was not returned to endologix for evaluation because it remains implanted.A clinical evaluation of the adverse event/incident was completed.An examination of medical records and/or medical imaging received by endologix shows the alto polymer leak complaint is unconfirmed.The transient hypotension complaint is confirmed.This is moderately consistent with the reported adverse event/incident.Proximal neck diameter + 7 was 15.5mm (should be 16-30.4mm) - off label.It is unlikely this contributed to the reported events.Procedure-related harms, device, user, procedure, or anatomy-relatedness of this complaint could not be determined with the medical records available for review.The final patient status was reported as discharged to home on postoperative day two in stable condition.No additional investigation of this reported adverse event/incident is planned.However, should additional information relevant to the investigation outcome become available, a follow-up report will be submitted.Endologix will continue to monitor this and similar adverse events/incidents.Corrections: g3: awareness date ¿ updated h6: investigation finding codes - remove code 3233 h6: investigation conclusion codes - remove code 11.
