Abdominal contrast-enhanced CT for diagnosing and transcatheter arterial embolization for treating spontaneous retroperitoneal hematoma / 中国介入影像与治疗学

ABSTRACT

Objective To observe the value of abdominal contrast-enhanced CT for diagnosis of spontaneous retroperitoneal hematoma(SRH)and transcatheter arterial embolization for treating SRH.Methods Data of 7 SRH patients were retrospectively analyzed,including 4 cases diagnosed with abdominal contrast-enhanced CT,1 case diagnosed with plain CT and 2 cases diagnosed with abdominal ultrasound.Transcatheter angiography was performed to explore the offending artery of SRH which were then treated with trancatheter arterial embolization.The total angiographic time,i.e.the time span between the first and the last angiography was recorded and the treatment effect was observed.Results Among 7 patients,the offending artery of SRH was identified and embolized,and 30 days follow-up showed stable condition in 6 cases.The offending artery of SRH was not found in 1 case who then received conservative medical treatment,and the condition remained stable.The total angiographic time in 4 cases diagnosed with abdominal contrast-enhanced CT were 32-60 min,with a median time of 47.5 min,while in the rest 3 were 36-80 min,with a median time of 63.0 min.Conclusion Abdominal contrast-enhanced CT was helpful to diagnosis and displaying the offending artery of SRH.Transcatheter arterial embolization was effective for treating SRH.
