C. Radiographic occlusion may be asymptomatic.

D. Angioplasty with stenting is better than radiation therapy for imme-

diate symptomatic relief.

E. Recurrent obstruction may be treated with thrombolysis, balloon

angioplasty, or repeat stenting.

B. TIPS is contraindicated in patients with hepatic encephalopathy.

C. Peritoneovenous shunting is an effective method of dealing with

malignant ascites.

D. TIPS is more beneficial in dealing with ascites from portal hyperten-

tomatic relief from malignant ascites.
