ABSTRACT
OBJECTIVE@#To discuss the diagnostic value of pneumoperitoneum helico-CT imaging (PHCT) in cases of post-operative peritoneal adhesion (POPA).@*METHODS@#We retrospectively analyzed the PHCT scan pictures from 32 consecutive patients with chronic abdominal pain or recurrent mechanical intestinal obstruction after abdominal operation.@*RESULTS@#In a normal peritoneal cavity without adhesion, an air distended dome-like space would be demonstrated with the abdominal organs arranged smoothly on the bottom of the shadow. Any additional shadow appearing in the dome-space would suggest adhesion or something abnormal. Positive findings of peritoneal adhesion were found in 30 of the 32 patients (93.75%). A spot adhesion at the abdominal wall making a kinking of intestine usually showed a cuneiform bulging shadow pointed to the roof of the dome-space. Organs involved in the adhesion may be single or multiple, including the liver, stomach, small intestine, colon, uterus, and omentum. In all the 32 patients, PHCT diagnosis was confirmed by the subsequent laparoscopy treatment.@*CONCLUSION@#PHCT imaging is valuable in making a definite diagnosis of POPA, particularly before a blind laparoscopic exploration. It is a replacement for laparoscopy but much simpler, and may offer a valuable help in dealing with the difficult cases of suspected POPA. A negative imaging is sometimes very important to an undetermined postoperative chronic abdominal pain.

Portal vein stricture complicated with superior mesenteric venous thrombosis is rarely seen in clinical practice. On December 26, 2009, a 51-year-old male patient who had a liver transplantation history was admitted to The General Hospital of Chinese People's Armed Police Forces with the chief complaint of intermittent abdominal pain and diarrhea.A plain and enhanced CT scan showed that the portal vein was constrictive and thrombosis had formed in the main trunk of the superior mesenteric vein, and varicose veins were seen in surrounding tissues of the esophagus. Edema was observed at the end of the ileum and cecum. The results of colonoscopy showed inflammatory changes and varicose veins of the colon. The patient received medical treatment. The thrombosis was dissolved 9 days later, and all symptoms disappeared 12 days later.
ABSTRACT
@# Objective To explore the application of 64-slice spiral CT angiography (CTA) in the evaluation of cerebral vascular disease. Methods 160 cases with suspected cerebral vascular disease underwent CTA with 64-slice spiral CT. Two dimensional and three dimensional reformation were performed in all cases including multiplanar reconstruction (MPR), maximum intensity projection (MIP), volume rendering (VR). Both axial and reformatted images were analyzed by two radiologists. Results 94 cases of 160 were diagnosed as abnormal, including 50 stenosis or obstructive disease, 21 aneurysm, 1 post-intravascular stent, 4 cliped aneurysm, 3 arteriovenous malformation, 4 moyamoya disease, 4 carotid-cavernous fistula, 4 venous sinus thrombus, 1 straight sinus occlusion with perpetual falcial sinus, 1 great cerebral venous aneurysm, 1 perpetual sublingual artery. Conclusion 64-slice spiral CTA is a valuable diagnostic method for various cerebral vascular disease.
