"right femoral cutdown (only access) 6,000 units of heparin given ivus (intravascular ultrasound) used to assess true lumen and aortic diameter 100cm marker pigtail and 300cm 4cm extended curve lunderquist wire the procedure was performed in the normal fashion using diagnostic wires and catheters to navigate into the true lumen of the dissection and verifying with ivus.After ivus measurements a 40-36 x 250 graft was selected with the possibility of a second piece.The proximal landing zone was about20- 25mm proximal to the debranch graft at the 3rd chest wire.Positioning and placement of the relay plus graft went as planned with the patient's vital signs stable.During the last deployment step, step 4 the patients blood pressure dropped to a systolic pressure in the mid 30's.Anesthesia gave medication to increase the bp with no improvement chest compressions were started and a code was called.The relay plus was left in place over the wire in the lower descending aorta to maintain hemostasis of the femoral artery during the code.No further imaging or angiograms were done".Patient outcome: "after an extended time of preforming cpr a time of death was called.Dr.(b)(6) spoke with the family and they agreed to an autopsy to determine the cause".
