RESUMEN
INTRODUCTION: There exists variation regarding the approach to anticoagulation and variceal hemorrhage (VH) prophylaxis among patients with cirrhosis and portal vein thrombosis (PVT). METHODS: A survey was distributed to gastroenterology and hepatology providers to assess the approach to anticoagulation and VH prophylaxis among patients with PVT in cirrhotic patients. RESULTS: Providers were more likely to start anticoagulation if the patient was listed for liver transplantation, was symptomatic, or had superior mesenteric vein thrombosis. For prevention of first VH, many providers opt for combination therapy with both nonselective beta blockers and variceal ligation. DISCUSSION: Although providers agree on the clinical scenarios that merit initiation of anticoagulation, practice variation was identified in the means of preventing first VH.

Third-spacing of fluid is a common complication in hospitalized patients with decompensated cirrhosis. In addition to ascites, patients with advanced cirrhosis may develop significant peripheral edema, which may limit mobility and exacerbate debility and muscle wasting. Concomitant kidney failure and cardiac dysfunction may lead to worsening hypervolemia, which may ultimately result in pulmonary edema and respiratory compromise. Diuretic use in such patients may be limited by kidney dysfunction and electrolyte abnormalities, including hyponatremia and hypokalemia. A slow, continuous form of ultrafiltration known as aquapheresis is a method of extracorporeal fluid removal whereby a pump generates a transmembrane pressure that forces an isotonic ultrafiltrate across a semipermeable membrane. This leads to removal of an ultrafiltrate that is isotonic to blood without the need for dialysate or replacement fluid as is necessary in other forms of continuous kidney replacement therapy. This technique has been utilized in other conditions including acute decompensated heart failure, with trials showing mixed, but generally favorable results. Herein, we present a series of our own experience using aquapheresis among patients with cirrhosis, review the literature regarding its use in other hypervolemic states, and discuss how we may apply lessons learned from use of aquapheresis in heart failure to patients with end-stage liver disease.
