Event Description

Following the completion of the removal of the aggressive maxilla orbital h&n tumor, two flaps were harvested for the reconstruction. A fibula free flap was used for the reconstruction of the maxilla and an alt flap to close the soft tissue. Both free flaps had a dp-sdp001 placed around the artery. 10 days post operation and after no issues in blood flow was detected, the probes came to be removed. Removal was performed on the h&n ward by a ward nurse who wasn't completely familiar with the cook doppler probe. The fibula flap monitor probe was removed easily with no incident. Upon removal of the alt flap it was reported that excessive force was required to remove wire and caused pain to patient. 24 hours later the alt flap was found to have an issue with blood flow and the patient returned to operating room for revision surgery. Upon opening, the arterial vessel leading to blood flow loss was separated and the flap had failed due to duration of ischemia. Afterwards, an alternative pectoralis major flap was harvested to anastomose to the vein of the recipient site. This led to a further 9 hour surgery and prolonged in-patient stay in hospital.
