[Surgery for iatrogenic obstruction of the second hepatic portal].

OBJECTIVE

To summarize the effects of surgery for iatrogenic obstruction of the second hepatic portal and the curative effects thereof.

METHODS

Seven patients, 5 males and 2 females, aged 25-38, with iatrogenic obstruction of the second hepatic portal, due to blocking of the reflux of hepatic vein by translocated stent in 4 cases and due to occlusion of hepatic vein local thrombosis and endometrial hyperplasia caused by broken wires in 3 cases, underwent removal of the foreign bodies and plastic operation of the second hepatic portal under temporary circulatory pause and hypothermic general anesthesia via the approach of incision of the pericardium and inferior vena cava. The patients were followed up for 6 months to 5 years.

RESULTS

After the operation the liver shrank and ascites was decreased significantly in all patients. The liver functions of all patients were normal during the follow-up and no complication or signs of recurrence were found. Ultrasonography and CT scan showed no stricture and stenosis.

CONCLUSION

Translocation of stent is the common reason of iatrogenic obstruction of the second hepatic portal. Operational procedure including removal of the foreign bodies and plastic operation of the second hepatic portal under temporary circulatory pause and hypothermic general anesthesia via the approach of incision of the pericardium and inferior vena cava is an effective radical surgical treatment for this complication.
