Review Case Reports
Portopulmonary hypertension as an indication for combined heart, lung, and liver or lung and liver transplantation: literature review and case presentation.
End-stage liver disease with severe portopulmonary hypertension (PPHTN), which is refractory to vasodilator therapies, is a contraindication for isolated liver transplantation (LT) because of the high mortality rate. Combined heart, lung, and liver transplantation (CHLLT) and combined lung and liver transplantation (CLLT) can be lifesaving options for these patients; however, these procedures have rarely been performed. A 52-year-old man had end-stage liver disease due to hepatitis C and PPHTN; the latter showed a suboptimal response to pulmonary vasodilator therapy with continuous intravenous treprostinil sodium and oral sildenafil citrate and was considered a contraindication to isolated LT. ⋯ Notably, 2 of the 6 CLLT patients expired within 24 hours of transplantation because of acute right heart failure. CHLLT should be considered for patients with refractory PPHTN. The assessment of preoperative cardiac function is a vital part of the decision to include heart transplantation in CLLT.

Comparative Study
Differential effects of plasma and red blood cell transfusions on acute lung injury and infection risk following liver transplantation.
Patients with chronic liver disease have an increased risk of developing transfusion-related acute lung injury (TRALI) from plasma-containing blood products. Similarly, red blood cell transfusions have been associated with postoperative and nosocomial infections in surgical and critical care populations. Patients undergoing liver transplantation receive large amounts of cellular and plasma-containing blood components, but it is presently unclear which blood components are associated with these postoperative complications. ⋯ Multivariate logistic regression determined that the number of transfused red blood cell units (adjusted odds ratio = 1.08, 95% confidence interval = 1.02-1.14, P < 0.01), the presence of perioperative renal dysfunction, and reoperation were significantly associated with postoperative infection. In conclusion, patients undergoing liver transplantation have a high risk of developing postoperative complications from blood transfusion. Plasma-containing blood products were associated with the development of TRALI, whereas red blood cells were associated with the development of postoperative infections in a dose-dependent manner.

The purpose of this study was to evaluate the results of percutaneous transhepatic management of anastomotic biliary strictures using the dual catheter placement technique (2 drainage catheters inserted via single percutaneous tract). The protocol of this retrospective study was approved by the institutional review board of our institution and written informed consent was waived. Percutaneous transhepatic biliary drainage and subsequent balloon dilation of anastomotic strictures were performed in 79 patients. ⋯ During the mean follow-up period of 34.5 ± 3 months (range, 24.4-38.5 months) in the 78 patients, the primary patency rates were 96%, 92%, and 91% at 1, 2, and 3 years, respectively. Seven (9%) of the 78 patients experienced recurrent symptoms at a mean of 15.4 ± 8.9 months (range, 6.1-26.2 months) after catheter removal. In conclusion, the dual catheter placement technique seems to be an easy, safe, and effective method with an acceptable catheter intervention period for the treatment of anastomotic strictures following LDLT.

Duct-to-duct anastomosis (DDA) and hepaticojejunostomy (HJ) are options for biliary reconstruction in patients undergoing adult-to-adult right lobe living donor liver transplantation (ARLDLT), after which biliary anastomotic stricture (BAS) is common as a complication. The risk factors for BAS are not clearly defined. We aimed to determine the rate of post-ARLDLT BAS in our center and its associated factors. ⋯ One patient required retransplantation for secondary biliary cirrhosis. In conclusion, BAS remains common after ARLDLT regardless of DDA or HJ. The graft cold ischemia time and postoperative acute cellular rejection are significantly associated with postoperative BAS.
