ABSTRACT
Objective ToinvestigatethevalueofDWIhyperintensityinvenoussinusindiagnosisandrecanalizationpredictionof cerebralvenoussinusthrombosis(CVST).Methods Clinicaland MRIdataof19patientswithCVST wereanalyzedretrospectively. BasedonDWIsignalcharacteristicsoftheCVST,thepatientsweredividedintoasthehyperintensegroupandthenon-hyperintense group.TheintervaltimebetweenthefirstMRIexaminationandtheonset,andtherecanalizationratewithin1 monthand3 months werecomparedbetweenthetwogroups.Results Therewere76 CVSTinthe19patients,withhyperintensein16venoussinus (21%)andin11patients(57.9%).Theintervaltimewaslongerinthehypertensegroupthanthenon-hypertensegroupbutnosta-tisticalsignificance[(12.81±11.10)daysversus(5.70±7.82)days,P=0.165].17patientsunderwentthesecond MRIexamination in1month,andtherecanalizationrateoftheobstructedsinuswaslowerinthehypertensegroupthanthenon-hypertensegroupwith nostatisticalsignificance(P=0.130).14patientsunderwenttheMRIexaminationafter3 months,andtherecanalizationrateofthe obstructedsinuswaslowerinthehypertensegroupthanthenon-hypertensegroupwithstatisticalsignificance(P=0.047).Conclu-sion ThehypertenseonDWIhashighsensitivityforthedetectionofsubacuteCVST.Thepresenceofhypertenseinoccludedsinus onDWIhasthepredictivevalueforvesselrecanalization.
