Hepatopulmonary syndrome: morbidity and survival after liver transplantation.

Hepatopulmonary Syndrome (HPS) is a triad of liver disease, intrapulmonary vascular dilatation (IPVD), and arterial deoxygenation. Orthotopic liver transplantation (OLT) constitutes the only effective treatment; however, adverse outcomes have been reported. The aim of this study was to evaluate the early morbidity and short- and long-term survival after OLT for patients with and without HPS. We studied 59 transplant recipients divided into 2 groups: with HPS (HPS group n = 25) and without HPS (control group, n = 34) before the OLT. IPVD was diagnosed using transthoracic contrast-enhanced echocardiography. Arterial deoxygenation was defined as PA-a,O(2) >or= 15 mm Hg. The HPS and control groups were homogeneous regarding age (P = .36; 43.8 +/- 12.2 vs 46.9 +/- 13.5), gender (P = .47), male/female ratio (68%:32% and 78%:22%, respectively), and severity of liver disease. The PaO(2) was significantly lower (74.9 +/- 12.1 vs 93 +/- 6.4 mm Hg; P < .001) and the PA-a,O(2) was significantly higher in the HPS group (30.3 +/- 10.6 vs 11.0 +/- 7.0; P < .001). The percentage of severe (n = 3) and very severe (n = 1) hypoxemia was 16%. There were no significant differences between HPS and control groups regarding short- (68% vs 77%; P = .27) and long-term survival (60% vs 64%; P = .67) as well as among patients with mild, moderate, severe, or very severe HPS and the control group (P = .53). Also, intensive care unit (ICU) stay (7.0 vs 5.5; P = .41), duration of mechanical ventilation (38.0 vs 27.5; P = .43), reintubation rate (32.0% vs 23.5%; P = .45), and early postoperative complications (P = .72) were not different. In conclusion, there were no significant differences regarding the outcomes of OLT for patients with versus without HPS related to early morbidity or short- and long-term survival.

Complications following transjugular intrahepatic portosystemic shunt: a retrospective analysis.

Transjugular intrahepatic portosystemic shunt (TIPS) has been the therapeutic option for severe decompensation of chronic liver disease and as a bridge to liver transplantation. The aim of this study was to analyze the complications of this procedure. The records of 47 patients (39 men) of mean age 48 years underwent TIPS procedures from 1998 to 2003 were reviewed. Forty-one patients received 45 successful TIPS; it failed in six patients. Improvement was observed in 20 of 28 patients with upper gastrointestinal bleeding (71%); 9 of 11 with ascites (82%); and 5 of 8 with impaired renal function (62%). The Child-Pugh scores improved in 6 of the 47 patients (13%). Transplantation was performed in 11 patients (23%). The complications were: encephalopathy (49%); infection (19%); renal failure (17%); TIPS migration to the portal vein (4%) and to the right atrium (4%). Mortality was 32% (15/47) over 3 months. Eight patients developed active bleeding during TIPS installation requiring mechanical ventilation and intensive care, and died within the first week. Other causes of death were sepsis (n = 2), liver failure (n = 1), accidental puncture of the Glisson's capsule leading to intra-abdominal bleeding (n = 1) and refractory upper gastrointestinal bleeding (n = 3). The latter four patients had TIPS placement failure. In conclusion, TIPS produced clinical improvement among 51% of patients with complications in 49%. The main complications were encephalopathy (49%), infection (19%), and renal failure (17%). The 3-month mortality rate after TIPS placement was 32%.
