Background Following on from an earlier study published in 2008 about left pulmonary artery(LPA)flow measured on serial echocardiography being strongly prognostic in left-sided congenital diaphragmatic hernia(CDH)and the ratio of LPA to right pulmonary artery(RPA)diameters being a simple and reliable indicator for commencing nitric oxide(NO)therapy,the ratio of LPA:RPA diameters(PA ratio orPAR)was hypothesized to possibly reflect cardiopulmonary stresses accompanying CDH *** Subjects with isolated left-sided CDH treated between 2007 and 2020 at a single pediatric surgical center were recruited and classified according to *** obtained retrospectively for subject demographics,clinical course,LPA/RPA diameters,and PAR were compared between survivors and *** value of PAR for optimizing the prognostic value of PA diameter data in CDH were analyzed with receiver operating characteristic(ROC)curve *** Of 65 subjects,there were 54 survivors(82.3%)and 11 non-survivors(17.7%);7 of 11 non-survivors died before surgical repair could be *** PAR for survivors(0.851±0.152)was significantly higher than for non-survivors(0.672±0.108)(p=0.0003).Mean PAR for non-survivors was not affected by surgical *** of survivors were:LPA≥2 mm(n=52 of 54;mean PAR=0.866±0.146)and RPA≥3mm(n=46 of 54;mean PAR=0.857±0.152).Non-survivors with similar LPA and RPA diameters to survivors had significantly lower mean *** curve cut-off for PAR was *** with high PAR(≥0.762)required high-frequency oscillatory ventilation/NO less than subjects with low PAR(1.71±0.68 days vs 3.20±0.87 days)(p1).Conclusions PAR would appear to be strongly correlated with clinical outcome in CDH and be useful for planning management of cardiopulmonary instability in CDH.

Approximately half of individuals diagnosed with colorectal cancer(CRC)will develop colorectal liver metastasis(CRLM)during the course of their disease(1,2).Liver resection is the only potentially curative treatment for patients with CRLM,yet less than 20%of individuals are candidates for resection due to the extent or location of liver disease,underlying liver function and/or presence of extrahepatic metastases(1,2).In addition,the oncologic benefit of liver resection for CRLM is limited by recurrence rates than can be as high as 70%(3).Liver transplantation(LT)for CRLM was initially proposed as an alternative treatment strategy in the early 1990s but was abandoned due to the initial poor outcomes(3,4).The concept of transplantation for CRLM was later revisited in the 2000s by a group in Oslo,Norway that reported promising results in the SECA-I pilot study(5).Since the completion of the SECA-I study,the Norwegian group has also published other promising data from the SECA-II study(6).In addition,other notable outcomes have been reported in the RAPID study(7),as well as another study from specialized centers in North America(8),both of which have revitalized the concept of LT for CRLM.
