Abstract:
Objective: To study the CT features and its diagnosis of spontaneous renal vein shunt (SPVA) in portal hypertension. Methods: Totally 220 cirrhosis patients with portal hypertension diagnosed clinically underwent multi-slice CT scanning. The parameters were 5 mm/6. 5 mm/2. 0 mm(collimation/effective thickness/interval) in 180 patients and 2. 5 mm/3. 2 mm/1. 6 mm in 40 patients. An arterial-phase (delaying 26-28 s) and a portal venous phase (55-60 s) were included. All images were showed by cine and CTA was displayed with volume rendering and thin-slab maximum projection when ah normal vessels were suspected. Results: The spontaneous renal shunt were found in 26 patients (11. 8%), including spleno left renal shunt(20 patients), gastro-left renal shunt (16 patients), and portal-right renal shunt(2 patients). The veins sur rounding renal hilum were rich and thick in 7 patients. Conclusion: The SPVA is not rare in portal hypertension, enhanced CT scan and angiography with multi-slice CT can effectively display the shunt vessels, contributing to the correct diagnosis and right therapy.
