AB020. Clinical characteristics and treatment of traumatic renal artery thrombosis

Background: To study the clinical characteristics, early diagnosis and treatment of traumatic renal artery thrombosis so as to recommend how to diagnose, treat and prevent traumatic renal artery thrombosis.

Methods: Summarize the clinical data of 10 patients with traumatic renal artery thrombosis and analyzed pathogenesis, clinical characteristics and the diagnosis and treatment procedure.

Results: The left renal artery thrombosis was 6 cases and the right renal artery thrombosis was 4 cases. Ultrasound reported that renal has reduced blood flow signal in one case and was confirmed by enhanced CT. The others were directly diagnosis renal artery embolization by enhanced CT scan. 4 cases of patients were treated with low molecular weight heparin calcium. Although the follow-up CT scan showed that injured renal had no obvious blood perfusion, the renal function was in normal range. 2 patients had renal hypertension, 1 case had poor control of blood pressure with drugs, so nephrectomy was performed.

Conclusions: Clinical symptoms and laboratory examinations of traumatic renal artery thrombosis had no specificity, color ultrasound is the early diagnosis method and enhanced CT scan is the effective mean of diagnosis. The early recovery of renal blood is effective treatment. Major concerns are renal function and blood pressure in follow up.
