MEDTRONIC LITERATURE REVIEW FOUND REPORT OF PATIENT COMPLICATIONS IN ASSOCIATION WITH SOLITAIRE STENT. THE STUDY ANALYZED DATA FROM 79 PATIENTS WITH LARGE VESSEL OCCLUSION WHO RECEIVED MECHANICAL THROMBECTOMY (MT). AUTHORS AIMED TO INVESTIGATE THE INCIDENCE, RISK FACTORS, AND FUNCTIONAL OUTCOMES WITH EARLY NEUROLOGICAL DETERIORATION (END) AFTER MT, AND THEREFORE AIM TO PROVIDE EVIDENCE FOR MORE PRECISE CLINICAL PRACTICE. OF THE 79 PATIENTS, THE MEDIAN AGE WAS 63 YEARS, 52 WERE MALES AND 27 WERE FEMALES. PATIENTS WITH OCCLUDED ARTERIES WERE: 40 AT MIDDLE CEREBRAL ARTERY (MCA) (50.6%), 20 AT INTERNAL CAROTID ARTERY (ICA) (25.3%), AND 19 AT VERTEBRAL BASILAR ARTERY (BA) (24.1%).

THE INCIDENCE OF END AFTER MT WAS 32/79 (40.5%), OF WHICH 12 HAD ISCHEMIC STROKE PROGRESSION, 11 HAD ENCEPHALEDEMA, AND NINE HAD SYMPTOMATIC CEREBRAL HEMORRHAGE. AMONG THE 32 END CASES, THREE DETERIORATED WITHIN 24 HOURS, FOUR WITHIN 24 TO 48 HOURS, AND 25 WITHIN 48 TO 72 HOURS.
