Background and Study Aim: The aim of this study was to investigate the influence of transcatheter arterial embolization on esophageal variceal pressure and portal hemodynamics.

Patients and Methods: Out of 18 cirrhotic patients with hepatocellular carcinoma, 12 underwent transcatheter arterial embolization and the remaining six patients underwent angiography alone as a control. We examined esophageal variceal pressure with an endoscopic pneumatic pressure sensor and portal blood flow with Doppler ultrasonography immediately before and 3 days after transcatheter arterial embolization or angiography.

Results: Angiography alone did not influence esophageal variceal pressure or portal blood flow. Transcatheter arterial embolization resulted in an increase in variceal pressure in five (42%) of the 12 patients and in a marked increase in portal blood flow in eight (88.9%) of nine patients, although no change in the endoscopic variceal findings was observed after transcatheter arterial embolization. The change in esophageal variceal pressure did not correlate with the change in portal blood flow. We could not find predictive factors for the elevation of variceal pressure after transcatheter arterial embolization.

Conclusion: Our study demonstrated that transcatheter arterial embolization resulted in an increase in esophageal variceal pressure in about half of the patients, bearing little relation to portal hemodynamic parameters.
