Abstract

The aim of this study was to assess the computed tomography angiography (CTA) manifestations of collateral circulations in patients with Budd‑Chiari syndrome (BCS). Eighty patients with BCS were examined by CT scan. Using the CTA images of the relevant blood vessels, including the affected hepatic veins (HVs) and inferior venae cavae (IVCs), the collateral circulations were reconstructed. In addition to obstructed HVs and IVCs, collateral circulations were found in each of the patients. The collateral circulations were classified as intrahepatic, extrahepatic and portosystemic pathways. Intrahepatic collateral pathways were further classified as the following six types: HV‑accessory HV (n=51, 63.8%), HV‑HV (n=6, 7.5%), HV‑accessory HV plus HV (n=6, 7.5%), IVC‑HV/accessory HV‑HV‑right atrium (n=5, 6.3%), HV‑umbilical vein (n=4, 5.0%) and HV‑inferior phrenic vein (n=8, 10.0%). Extrahepatic collateral pathways included IVC‑lumbar‑ascending lumbar‑hemiazygos/azygos vein (n=80, 100.0%), IVC‑left renal‑ascending lumbar‑hemiazygos vein (n=75, 93.8%), IVC‑left renal‑inferior phrenic vein (n=49, 61.3%), IVC‑renal ‑peri‑renal ‑superficial epigastric vein (n=26, 32.5%) and superficial epigastric vein (n=12, 15.0%) types. The CTA characteristics of each type of collateral circulation were demonstrated. In conclusion, the present study revealed that CTA is able to show the intra- and extrahepatic collateral circulations of patients with BCS, which may be useful for therapeutic planning.
