    LITERATURE WAS REVIEWED REGARDING 'THE ¿MUSCLE WONTON¿ REPAIR ¿ A CASE SERIES OF INTERNAL CAROTID ARTERY INJURIES AT A SINGLE CENTRE DURING ITS 10-YEAR EXPERIENCE IN ENDOSCOPIC TRANSSPHENOIDAL PITUITARY SURGERY'. THE TIME FRAME OF THIS STUDY WAS JANUARY 2010 TO DECEMBER 2019. MULTIPLE MANUFACTURER¿S DEVICES WERE USED IN THE STUDY POPULATION. THE FOLLOWING MEDTRONIC DEVICES WERE USED: PIPELINE FLOW DIVERTERS WERE USED TO TREAT AN INTERNAL CAROTID ARTERY (ICA) INJURY. AMONG PATIENT ADVERSE EVENTS INCLUDED: THREE PIPELINE STENTS WERE DELIVERED, AND A POST-PROCEDURE CT HEAD REVEALED NO EVIDENCE OF ISCHAEMIA, BLEEDING OR HYDROCEPHALUS, DESPITE SHOWING THE DEFECT THROUGH WHICH THE ICA TEAR OCCURRED. TWO DAYS POST-INJURY, A REPEAT ANGIOGRAM SHOWED A PERSISTENT LEAK OF THE RIGHT ICA, AND IT WAS DECIDED TO PLACE A FOURTH PIPELINE STENT WITHIN THE CONSTRUCT, WHICH INITIALLY SEALED THE IATROGENIC TEAR. UNFORTUNATELY, THE PROXIMAL END OF THE STENT FAILED TO OPEN DESPITE ATTEMPTS MADE TO RECTIFY THIS USING TWO TYPES OF REMODELLING BALLOONS. A PARENT VESSEL OCCLUSION WAS EVENTUALLY PERFORMED IN VIEW OF A RAPIDLY ACCUMULATING CLOT ON THE FOURTH PIPELINE STENT AND THE PATIENT WAS STABLE FOLLOWING THIS. THE PATIENT REMAINED ASYMPTOMATIC AND DID NOT SHOW ANY DETERIORATION IN IMAGING OR CLINICAL SYMPTOMS. NO FURTHER INFORMATION WAS PROVIDED PERTAINING TO MEDTRONIC PRODUCTS.
