Objective: To discuss the occurrence of thrombosis in portal system of patients with cirrhotic portal hypertension after devascularization and the methods for treatment and prevention.
Methods: The clinical data of 113 patients with cirrhotic portal hypertension after the devascularization were collected and analyzed retrospectively, and the occurrence time, parts as well as the treatment and prevention methods were discussed.
Results: Among the 113 patients, 33 of them were found with thrombosis in their portal system, and the occurrence rate was 29.2%. The occurrence time of thrombosis was 2-15 days post-devascularization, and the median time was 6 days post-operation. Among the 33 cases with thrombosis, there were 19 cases of splenic vein thrombosis, 10 cases of portal thrombosis, and 4 cases of both of them. After the thrombolytic therapy, the thrombosises in 30 cases disappeared.
Conclusions: Most of the thrombosises in portal system happen in splenic vein post-devascularization. Avoiding clamping the trunk of splenic vein in the operation and taking thrombolytic therapy at the early stage after the operation can effectively prevent the occurrence of thrombosis.

Vascular liver diseases (VLDs) include different pathological conditions that affect the liver vasculature at the level of the portal venous system, hepatic artery, or venous outflow system. Although serological investigations and sometimes histology might be required to clarify the underlying diagnosis, imaging has a crucial role in highlighting liver inflow or outflow obstructions and their potential causes. Cross-sectional imaging provides a panoramic view of liver vascular anatomy and parenchymal patterns of enhancement, making it extremely useful for the diagnosis and follow-up of VLDs.

: Contrast-enhanced ultrasound (CEUS) is a non-invasive imaging technique with similar accuracy to CT and MRI for the diagnosis of hepatocellular carcinoma (HCC). CEUS offers several advantages in patient populations who have contraindications for CT or MRI. There are limited prospective studies in the United States evaluating the diagnostic equivalence of CEUS following transcatheter arterial chemoembolization (TACE) with same-day CT/MRI.

The non-invasive assessment of disease severity remains pivotal in patients with chronic liver disease (CLD) as it has wide implications in predicting liver-related complications or death. Shear-wave elastography (SWE) is an emerging ultrasound-based method to non-invasively measure liver stiffness. The aim of our study was to evaluate two-dimensional (2D) and point (p) SWE to predict the presence of esophageal varices (EV) or clinically significant portal hypertension (CSPH).

Background: Conventional approaches for lumbar far lateral discectomy range from open approaches to newer minimally invasive approaches such as tubular discectomy and single portal endoscopic discectomy. We present a case of a patient suffering with a left L3-4 and left L4-5 extraforaminal disc herniation who was treated successfully with a left sided bitubular, biportal endoscopic 2 level far lateral discectomy.

Cardiovascular involvement in Leishmania sp. infections still requires further elucidation, with cutaneous and organic changes being more frequently observed. The aim of this study was to conduct a systematic review of cardiovascular involvement in dogs with canine visceral leishmaniasis, considering a publication span of over 80 years.
