Abstract Background Our purpose is to compare the stent patency and clinical outcome of trans-jugular intra-hepatic porto-systemic shunt (TIPS) through the left branch portal vein (TIPS-LPV) to the standard TIPS through the right branch (TIPS-RPV). We retrospectively reviewed all patients (n = 54) with refractory portal hypertension who were subjected to TIPS-LPV at our institute (TIPS-LPV) between 2016 and 2018. These patients were matched with 56 control patients treated with the standard TIPS-RPV (TIPS-RPV). The 2 groups were compared regarding the stent patency rate, encephalopathy, and re-interventions for 1 year after the procedure. Results TIPS-LPV group showed 12 months higher patency rate (90.7% compared to 73.2%) (P < 0.005). The number of the encephalopathy attacks in the TIPS-LPV group was significantly lower than that of the TIPS-RPV group at 6 and 12 months of follow-up [P = 0.012 and 0.036, respectively]. Re-bleeding and improvement of ascites were the same in the two groups [P > 0.05]. Patients underwent TIPS-LPV needed less re-interventions and required less hospitalizations than those with TIPS-RPV [P = 0.039 and P = 0.03, respectively]. Conclusion The new TIPS approach is to extend the stent to LPV. This new TIPS-LPV approach showed the same clinical efficiency as the standard TIPS-RPV in treating variceal bleeding and ascites. However, it proved a better stent patency with lower rates of re-interventions, encephalopathy, and hospital admissions than TIPS through the right branch.

Abstract Background Portal hypertension is a major complication resulting from obstruction of portal blood flow, like cirrhosis or portal vein thrombosis, that leads to portal hypertension. MDCT angiography has become an important tool for investigation of the liver as well as potentially challenging varices by detailing the course of these tortuous vessels. This information is decisive for liver transplantation as well as for common procedures in which an unexpected varix can cause significant bleeding. Results This study included an assessment of 60 cases of portal hypertension (28 males and 32 females), their age ranged from 42 to 69 years (mean age = 57.2 ± 6.63). All patients were diagnosed with portal hypertension, underwent upper GI endoscopy followed by a triphasic CT scan with CT angiographic assessment for the screening of gastro-esophageal varices. CT is highly sensitive as compared to upper GI endoscopy (sensitivity 93%) in detecting esophageal varices. Gastric varices detected by CT in 22 patients (37%) compared to 14 patients (23%) detected by endoscopy. While paraesophageal varices were detected in 63% of patients and retro-gastric varices in 80% of patients that were not visualized by endoscopy. Our study reported that the commonest type of collaterals were the splenic collaterals, and we also found there is a significant correlation between the portal vein diameter and the number of collaterals as well as between the portal vein diameter and splenic vein diameter. Conclusions Multi-slice CT serves as an important non-invasive imaging modality in the diagnosis of collaterals in cases of portal hypertension. CT portography can replace endoscopy in the detection of high-risk varices. It also proved that there is a correlation between portal vein diameter, splenic vein diameter, and number of collaterals.

AbstractIntroduction: We describe a technique we call “Meso-transjugular intrahepatic portosystemic shunt (MTIPS)” for relief of portal hypertension secondary to portal vein thrombosis (PVT) using combined surgical and endovascular technique. Materials and Methods: Nine adult patients with PVT underwent transjugular intrahepatic portosystemic shunt through a combined transjugular and mesenteric approach (MTIPS), in which a peripheral mesenteric vein was exposed through a minilaparotomy approach. The right hepatic vein was accessed through a transjugular approach. Mechanical thrombectomy, thrombolysis, and angioplasty were performed when feasible to clear PVT. Results: All patients had technically successful procedures. Patients were followed up for a mean time of 13.3 months (range: 8 days to 3 years). All patients are still alive and asymptomatic. Conclusion: We conclude that MTIPS is effective for the relief of portal hypertension secondary to PVT.

ABSTRACT: Pulsed Doppler ultrasound was used to evaluate portal blood flow, portal velocity and portal congestion index in 24 healthy sheep divided into groups (lambs, yearlings and ewes), according to age. Measurements were performed at the 11th right intercostal space using ideal insonation angle and uniform insonation method. Mean values obtained in each group were compared with one-way ANOVA, followed by Tukey post-hoc test. Portal velocity and portal blood flow were statistically similar between the groups (P>0.05). Mean portal velocity were 17.75; 17.13 and 16.75; while mean portal blood flow were 26.65; 31.04 and 24.32 for lambs, yearlings and ewes, respectively. Portal congestion index was statistically distinct between the groups and values for lambs, yearlings and ewes were 0.009; 0.058 and 0.09, respectively (P<0.01). Statistical differences were observed in portal vein diameter, portal vein area and portal congestion index between the groups, presumably due to influence of weight and not to age.

Aim. The frequency of the Right Posterior Sectional Bile Duct (RPSBD) hump sign in cholangiogram when it crosses over the right portal vein known as Hjortsjo Crook Sign and the bile duct anatomy are studied. Knowledge of the implication of positive sign can facilitate safe resection for both bile duct and portal vein. Methods. Prospectively, we included 237 patients with indicated ERCP during a period from March 2010 to January 2015. Results. The mean age (±SD) and male to female ratio were 38.8 (±19.20) and 1 : 1.28, respectively. All patients are Arab from Middle Eastern origin, had biliary stone disease, and underwent diagnostic and therapeutic ERCP. Positive Hjortsjo Crook Sign was found in 17.7% (42) of patients. The sign was found to be equally more frequent in Nakamura’s RPSBD anatomical variant types I, II, and IV in 8.4% (20), 6.8% (16), and 2.1% (5), respectively, while rare anatomical variant type III showed no positive sign. Conclusion. Hjortsjo Crook Sign frequently presents in RPSBD variation types I, II, and IV in our patients.

Background: Spontaneous portosystemic shunts (SPSS) are one of the hallmarks of Budd-Chiari syndrome (BCS). Ultrasound can accurately show the location and type of portosystemic collaterals. Objectives: To study the sonographic feature of SPSS in patients with BCS and to evaluate differences in the main portal vein diameter among multiple types of portosystemic shunts. Patients and Methods: Ultrasonographies of 44 patients with SPSS among 352 BCS patients between June 2000 and November 2015 were reviewed retrospectively. The SPSS in 44 BCS patients were first detected by ultrasound and then confirmed via digital subtraction angiography (DSA), computed tomography angiography (CTA) or magnetic resonance venography (MRV). The location, course, diameter and hemodynamics of the spontaneous portosystemic shunts were observed by ultrasound. In addition, one-way analysis of variance (ANOVA) was performed to evaluate the difference in the main portal vein diameter between the different shunt types. Results: The blood drainage patterns of SPSS in 44 of 352 patients with BCS were classified as the following five types: portal-umbilical shunts (15/44), portal-hepatic shunts (11/44), portal-accessory hepatic shunts (6/44) (the accessory hepatic veins included the inferior right hepatic vein and the caudate lobe vein), splenorenal shunts (8/44) and main portal vein-inferior vena cava shunts (4/44). The corresponding hemodynamics of the five types mentioned above were obtained. Main portal vein-inferior vena cava shunts had a significantly larger mean portal trunk diameter compared with all other types (P < 0.05 for all comparisons). In addition, the mean portal trunk diameters in portal-umbilical shunts and portal-hepatic shunts were obviously larger than that of splenorenal shunts (P < 0.05), while there were no statistically significant differences between the other types. Conclusion: Spontaneous portosystemic shunts are not rare in patients with BCS. Ultrasound is a reliable means for their diagnosis and it offers substantial information for use in clinical treatment.
