Supplementary Material for: Postmortem Biopsy to Obtain Lung Tissue in Congenital Diaphragmatic Hernia

<b><i>Background:</i></b> The accrual of human tissues from autopsies for diagnostic and translational research has decreased significantly over the last decades. <b><i>Objectives:</i></b> The objective of this study was to evaluate our experience with lung biopsy through a minithoracotomy as an alternative for obtaining postmortem tissue when full autopsy is refused in congenital diaphragmatic hernia (CDH) patients. <b><i>Methods:</i></b> Within 2 h of death we routinely asked parents for permission to perform an autopsy. Starting in 2001, parents who refused autopsy were asked permission for a postmortem lung biopsy. Pathology autopsy and biopsy reports were compared to clinical records. <b><i>Results:</i></b> Between 2001 and 2009, 46 patients died from CDH. Permission for autopsy was granted in 5 patients (11%). Of the remaining 41 patients, the parents of 15 (33%) agreed to postmortem lung biopsy. In all cases, additional findings were reported from the autopsy or biopsy, without changing the originally reported cause of death<i>.</i> In 1 case, we isolated fibroblasts from the lung biopsy using standardized cell culture techniques. Parents were able to take their child home with a minimal delay following biopsy. <b><i>Conclusions:</i></b> Parents refusing a full autopsy frequently agree to postmortem organ biopsy. This approach should therefore be considered as a valuable alternative, when permission for full autopsy is declined, for obtaining human tissues for both diagnostic and research purposes and is potentially applicable to other anomalies.
