Transjugular intrahepatic portosystemic shunts for refractory ascites: assessment of clinical and hormonal response and renal function.
Cirrhosis is frequently complicated by ascites that may become resistant to diuretic therapy. Transjugular intrahepatic portosystemic shunts (TIPS) represent a new treatment for this debilitating condition. The aim of this study was to ascertain the clinical efficacy of TIPS, as well as its impact on renal function and on hormonal parameters. Five inpatients with refractory ascites were studied prospectively before TIPS, and 3 and 14 days after TIPS. After TIPS, ascites completely resolved or was minimal in all patients. Diuretics were discontinued in three subjects and decreased by at least 50% in two. One patient developed liver failure after TIPS and required liver transplantation; the others remained stable after a mean follow-up of 14 months. Mean urinary sodium excretion increased from 2.1 +/- 0.6 mEq/24 hr before TIPS to 13.0 +/- 4.3 mEq/24 hr 14 days after TIPS. Mean serum creatinine and glomerular filtration rate also tended to improve during the study period. With the exception of the patient who developed liver failure, plasma aldosterone concentration decreased from a mean of 126.0 +/- 29.9 ng/dL to 22.8 +/- 6.8 ng/dL (P = .04), and plasma renin activity decreased from a mean of 9.0 +/- 3.0 micrograms/L/h to 0.9 +/- 0.1 microgram/L/h (P = .08). Additionally, 19 patients who underwent TIPS for refractory ascites outside of this protocol were followed prospectively for a mean of 282 days. Clinical improvement in ascites control was noted in 74%, and the mean dose of diuretics was decreased by more than 50%. Nonresponders more often had underlying renal disease. In conclusion, TIPS is an effective therapy for refractory ascites in most patients.(ABSTRACT TRUNCATED AT 250 WORDS)
