Article Title: Narrative review of portal vein thrombosis in cirrhosis: pathophysiology, diagnosis, and management from an interventional radiology perspective

doi: 10.21037/cdt-21-98

Figure Lengend Snippet: Case 2: M, 69, with ETOH cirrhosis and bleeding gastric varices requiring Sengstaken Blakemore tube in the stomach and esophagus. (A and B) are coronal CT scans of upper abdomen revealing partially occlusive thrombus in the portal vein and large gastric varices (marked by arrows). (C) is a splenoportal venogram obtained by catheter through the trans splenic route. It reveals partially occlusive thrombus in the main portal vein and poorly visualized intrahepatic portal venous branches, specifically in the right lobe (marked by arrow) due to chronic partial occlusion. (D) reveals presence of large gastric varix (marked by arrow) with left and posterior gastric afferent veins. (E) is a portal venogram after balloon venoplasty and mechanical thrombectomy with Angiojet thrombectomy device and TIPS placement. It reveals presence of thrombus in the main portal vein (marked by arrow) proximal to the TIPS. (F) shows FlowTriever2 catheter and disk (marked by white arrow) and a 20 French FlowTriever 20 aspiration catheter (marked by black arrow). (G) is splenoportal venogram status post mechanical thrombectomy, revealing complete resolution of the thrombus in the main portal vein and persistence of gastric varices after removal of the Sengstaken Blakemore tube. (H) is splenoportal venogram obtained after PARTO procedure with occlusion of the descending inferior phrenic vein with amplatz vascular plug (marked by black arrow) and embolization of the afferent posterior gastric veins with amplatz vascular plugs (marked by white arrows) after embolization of the varix with gelfoam slurry. Venogram reveals complete non visualization of the gastric varices and patent main portal vein. TIPS, transjugular intrahepatic portosystemic shunt; ETOH, ethanol; PARTO, plug-assisted retrograde transvenous obliteration.

Article Title: First off Label Endovascular Clinical Experience to Treat Diffuse Cerebral Venous Sinus Thrombosis Using the INARI FlowTriever System: Case Report

doi: 10.3389/fneur.2021.778842

Figure Lengend Snippet: Transvenous endovascular mechanical thrombectomy using the INARI FlowTriever system. (A–C) Right femoral venous access was obtained by placing a 22F GORE DrySeal Flex Introducer Sheath with pre-dilation using 8F, 10F, 14F then 18F dilators. 2 cc of air was inflated in the GORE DrySeal Flex valve to stop back flow of venous blood. (D,E) After selecting the left internal jugular vein; The INARI Triver20 large bore aspiration catheter was advanced with its dilator over the TAD2 exchange wire (Over-the-wire technique) and then the dilator was removed. (F–H) large volume venous clots retrieved using the Vect074 reperfusion catheter and Solitaire stent retriever and negative pressure applied with a 60 cc syringe through the INARI Triver20 large bore aspiration catheter. Anticoagulation with heparin was resumed after the procedure.

Article Snippet: The patient was deemed moderate to high risk of unfavorable outcome and was subsequently underwent mechanical endovascular venous thrombectomy using the INARI FlowTriever system and large clot burden was aspirated with a reasonable safety profile.
