Event Description

Medtronic received a report that the patient had a previously ruptured anterior communicating artery aneurysm that was coiled and had a neck remnant that had grown and required treatment, as well as a posterior wall component that was unprotected by prior coils.Th physician decided that flow diversion was most adequate treatment for this case.His plan was to place the pipeline distally in ipsilateral (right) a2 into right a1.Accessing the a2 was difficult, requiring multiple attempts with multiple types of wires.Once the a2 was accessed with the wire, phenom27 was advanced past the target to begin pipeline placement.Measurements were obtained and ped2-300-16 was chosen by the physician to be optimal size.The device was loaded into the phenom27 and deployed normally.Follow up imaging displayed adequate placement and patency of the device.During recovery overnight the patient experienced an intracranial hemorrhage.The pipeline was used for an indication that is approved (on-label).The reported device and any accessory devices were prepared as indicated in the instructions for use (ifu).The patient was undergoing surgery for treatment of a saccular, unruptured anterior communicating artery aneurysm with a max diameter of 2.8mm and a 3mm neck diameter.The landing zone was 2.2mm at the distal end and 2.6mm at the proximal end.It was noted the patient's vessel tortuosity was moderate.Dapt (dual antiplatelet treatment) was administered.The angiographic result post procedure was successful flow diversion of acom aneurysm with pipeline embolization device.Placed distally in right a2, proximally in right a1.Ancillary devices include a penumbra neuron max sheath, navien 058 guide catheter, penom27 microcatheter, stryker synchro2 guidewire (x3), synchro10 guidewire, and scientia aristotle24 guidewire.Additional information was received that the patient was doing much better.The patient received external ventricular drain and was intubated (on (b)(6) 2023).The patient is improving, and the physician placed a shunt this week.The physician was unsure of the cause but per physician was confident it was not the pipeline.
