“…At present a new type of CT scan, mul- tidetector CT (MD-CT), provides excellent images to visualize portosystemic collaterals in patients with portal hypertention. [12][13][14] Although PTP or direct varicography may show portosystemic collateral vessels with intense enhancement, if bleeding is suspected, MD-CT might be considered for early diagnosis and the evaluation of collateral vessels pretreatment, as well as for posttreatment screening of new varicose formations.…”

Successful embolization therapy for bleeding from jejunal varices after choledochojejunostomy: Report of a case

et al. 2010

We report a case of successful embolization of jejunal varices that were the cause of massive gastrointestinal bleeding from a choledochojejunostomy site, resulting from obstruction of the extrahepatic portal vein. A 42-year-old man who had undergone choledochojejunostomy for intrahepatic and choledochal stones was readmitted after he started passing massive dark bloody stools. Gastrointestinal endoscopic examination and angiography could not identify the source of bleeding. Percutaneous transhepatic portography showed obstruction of the right branches of the portal vein. The formation of jejunal varices at the site of choledochojejunostomy was revealed by portography and by cholangioscopy, suggesting the varices as the cause of massive bleeding. Bleeding could not be controlled long-term by cholangioscopic sclerosing therapy. We finally stopped the bleeding by embolizing a jejunal vein to the afferent loop.

“…In addition, on CT, the dilated left gastric veins and the varices around the lower part of the esophagus, particularly on the right aspect of the esophagus, were observed in all cases, which also illustrated that there were fewer varices at the 9:00 position. The incidence of hemorrhage in this drainage pathway is ~87.76% (15). This may explain the sharp decrease in the likelihood of hemorrhage at the 9:00 position in the 35-40 cm group.…”

Abstract. The aim of the present study was to investigate the predilection position of hemorrhagic stigmata (HS) in patients with esophageal variceal hemorrhage and provide guidance on endoscopic therapy for esophageal varices. The clinical characteristics, particularly the endoscopic manifestations of HS, in the patients who presented with gastroesophageal variceal hemorrhage and cirrhosis between January 2003 and December 2013 at our hospital were summarized and patients were grouped according to the distance of the lesion site to incisors at 35-40 and ~30 cm. The association between the location of HS and active hemorrhage was assessed. The location of hemorrhage and HS at 35-40 cm from the incisors was more common in esophageal varices patients, followed by the location at ~30 cm from the incisors (P<0.0001). The incidence of HS in esophageal varices patients in the 35-40 cm group was significantly higher than that in the ~30 cm group except

“…The anatomy of the hepatic vascular system is very important in the planning of hepatic surgery, and sufficient understanding of the anatomy and variations in the system is crucial in order to choose the adequate surgery plan and to avoid complications. MSCTA can be used to accurately demonstrate the vascular anatomy, possible variations and relationship with surrounding tissues ( 1 2 12 13 14 ).…”

ObjectiveTo investigate the efficiency of spectral computed tomography (CT) optimal monochromatic images in improving imaging quality of liver vessels.Materials and MethodsThe imaging data of 35 patients with abdominal CT angiography were retrospectively analyzed. Hepatic arteries, portal veins, and hepatic veins were reconstructed with mixed energy (quality check, QC), 70 keV and optimal monochromatic mode. Comparative parameters were analyzed including CT value, image noise (IN), contrast-to-noise ratio (CNR), signal-to-noise ratio (SNR), and subjective qualitative analysis.ResultsThe optimal monochromatic value for assessment of the common hepatic artery, portal vein, and hepatic vein ranged between 49 keV and 53 keV, with a mean of 51 keV. There were statistically significant differences (p < 0.001) among the optimal monochromatic, 70 keV and QC images with regards to the hepatic vascular CT value, IN, CNR, SNR, and subjective qualitative score. CNR of the common hepatic artery in the optimal monochromatic, 70 keV and QC groups was 24.6 ± 10.9, 18.1 ± 8.3, and 11.6 ± 4.6, respectively (p < 0.001) with subjective scores of 4.7 ± 0.2, 4.0 ± 0.3, and 3.6 ± 0.4, respectively (p < 0.001). CNR of the hepatic portal vein was 6.9 ± 2.7, 4.3 ± 1.9, and 3.0 ± 2.1, respectively (p < 0.001) with subjective scores of 4.5 ± 0.3, 3.9 ± 0.4, and 3.3 ± 0.3, respectively (p < 0.001). CNR of the hepatic vein was 5.7 ± 2.3, 4.2 ± 1.9, and 2.7 ± 1.4, respectively with subjective scores of 4.3 ± 0.3, 3.8 ± 0.4, and 3.2 ± 0.3, respectively (p < 0.001).ConclusionOptimal monochromatic images can lead to improvement in the imaging parameters and optimization of the image quality of the common hepatic artery, hepatic portal vein and hepatic vein compared with conventional mixed kV and with 70 keV datasets.
