Abstract:
Objective To study the application of multi-slice spiral CT(MSCT) portography in diagnonsis of pancreatic portal hypertension. Methods Forty-seven patients with lesion in body or tail of pancrease,47 normal subjects and 126 patients with portal hypertension underwent MSCT portography with LightSpeed 16 CT scanner. The inner diameter of portal system and the main collateral veins were measured in maximun intensity projection (MIP) image. The volume of liver and spleen were also measured in volume rendering (VR) image. The liver parenchyma and main portal vein enhancement in portal vein phase were also taken. The endoscopy examination was made in 57 patiens with portal hypertension. Results In 47 patiens with lesion in body or tail of pancreas , stenosis or occlusion of spleen vein were found in 38 patients(pancreatic portal hypertension in 27 patients, chronic and acute pancreatitis in 11 patients). In 38 patients with pancreatic portal hypertension, esophageal varices was found in 5 patients(13.2%), gastric fundus varix in 25 patients (65.8%), gastric body variees in 22 patients (57.9%), short-gastric vein/post-gastric vein(SGV/PGV) in 26 patients (68.4%), coronal gastric vein in 26 patients (68.4%),dilated gasto-omenta vein in 24 patients(63.2%), mesenterica varicesin 1 patient, splenic vein occlusion in 14 patients (36.8%), splenic vein stenosis in 23 patinets(63.2%). Conclusions The patients with pancreatic portal hypertension were demonstrate characteristic changes in MSCT portography. The MSCT portography is helpful in etiological diagnosis of pancreatic portal hypertension by supplying images in vessel morphology.
