Successful spleno-renal shunt and splenectomy in two patients with alpha-1-antitrypsin deficiency.

Recent evidence suggests that the cirrhosis of alpha-1-antitrypsin deficiency is not invariably fatal as it was previously thought. Portal hypertension is often the major determinant of survival. The few reports of porta-systemic venous anastomosis in this disorder have shown poor results or uncertain outcome. Thus, doubts exist as to whether porta-systemic shunts should be performed in alpha-1-antitrypsin deficiency. Two patients with alpha-1-antitrypsin deficiency (PiZZ) and associated portal hypertension, cirrhosis, and hypersplenism underwent splenorenal shunt and splenectomy 8 yr ago, and both have done well. One of the patients has chronic severe headaches, diarrhea, exudative enteropathy, sinusitis, and hematuria, all uncommon in alpha-1-antitrypsin deficiency but possibly related to the antienzyme deficiency. She also has a higher trypsin inhibitory capacity than is generally reported in ZZ individuals. Based on the experience with these 2 patients, it appears that alpha-1-antitrypsin deficiency with cirrhosis is not a valid contraindication to the performance of a portasystemic shunt.
