Efferent Pathways

Varices commonly occur in liver cirrhosis patients and are classified as esophageal (EV), gastroesophageal (GEV), or isolated gastric (IGV) varices. These vessels may be supplied and drained by several different afferent and efferent pathways. A working knowledge of variceal anatomy is imperative for Interventional Radiologists performing transjugular intrahepatic portosystemic shunt and embolization/obliteration procedures. This pictorial essay characterizes the angiographic anatomy of varices in terms of type and frequency of venous filling and drainage, showing that different varices have distinct vascular anatomy. EVs typically show left gastric vein filling and “uphill” drainage, and GEVs and IGVs exhibit additional posterior/short gastric vein contribution and “downhill” outflow. An understanding of these variceal filling and drainage pathways can facilitate successful portal decompression and embolization/obliteration procedures.

AbstractTransjugular intrahepatic portosystemic shunt (TIPS) reduces portal hypertension in patients with liver cirrhosis. The exact cardiac consequences of subsequent increase of central blood volume are unknown. Cardiovascular magnetic resonance (CMR) imaging is the method of choice for quantifying cardiac volumes and ventricular function. The aim of this study was to investigate effects of TIPS on the heart using CMR, laboratory, and imaging cardiac biomarkers. 34 consecutive patients with liver cirrhosis were evaluated for TIPS. Comprehensive CMR with native T1 mapping, transthoracic echocardiography, and laboratory biomarkers were assessed before and after TIPS insertion. Follow-up (FU) CMR was obtained in 16 patients (47%) 207 (170–245) days after TIPS. From baseline (BL) to FU, a significant increase of all indexed cardiac chamber volumes was observed (all P < 0.05). Left ventricular (LV) end-diastolic mass index increased significantly from 45 (38–51) to 65 (51–73) g/m2 (P =  < 0.01). Biventricular systolic function, NT-proBNP, high-sensitive troponin T, and native T1 time did not differ significantly from BL to FU. No patient experienced cardiac decompensation following TIPS. In conclusion, in patients without clinically significant prior heart disease, increased cardiac preload after TIPS resulted in increased volumes of all cardiac chambers and eccentric LV hypertrophy, without leading to cardiac impairment during follow-up in this selected patient population.

Cirrhotic Patients

Lipopolysaccharide (LPS) and endothelin- (ET-) 1 may aggravate portal hypertension by increasing intrahepatic resistance and splanchnic blood flow. In the portal vein, after TIPS shunting, LPS and ET-1 were significantly decreased. Our study suggests that TIPS can benefit cirrhotic patients not only in high hemodynamics related variceal bleeding but also in intestinal bacterial translocation associated complications such as endotoxemia.
