Lung transplantation (LTx) may be denied for children on extracorporeal membrane oxygenation (ECMO) due to high risk of cerebral hemorrhage. Rarely has successful LTx been reported in children over 10 years of age receiving awake or ambulatory veno‐venous ECMO. LTx following support with ambulatory veno‐arterial ECMO (VA ECMO) in children has never been reported to our knowledge. We present the case of a 4‐year‐old, 12‐kg child with heritable pulmonary artery hypertension and refractory right ventricular failure. She was successfully bridged to heart–lung transplantation (HLTx) using ambulatory VA ECMO. Initial resuscitation with standard VA ECMO was converted to an ambulatory circuit using Berlin heart cannulae. She was extubated and ambulating around her bed while on VA ECMO for 40 days. She received an HLTx from an oversized marginal lung donor. Despite a cardiac arrest and Grade 3 primary graft dysfunction, she made a full recovery without neurological deficits. She achieved 104% force expiratory volume in 1 s 33 months post‐HLTx. Ambulatory VA ECMO may be a useful strategy to bridge very young children to LTx or HLTx. Patient tailored ECMO cannulation, minimization of hemorrhage, and thrombosis risks while on ECMO contributed to a successful HLTx in our patient.
Routine histopathology of nasal polyps in ESS for bilateral CRS with polyps yields few unexpected and management-altering diagnoses. It carries a significant cost to the healthcare system. In cases of bilateral CRS with no other concerning clinical features, clinicians should exercise judgment in submitting polyp specimens for pathology rather than routinely sending polyps for histopathologic analysis.
BackgroundControversy regarding the usefulness of routine histopathological examination of bilateral nasal polyps removed during endoscopic sinus surgery to identify occult diagnoses still exists. There is a paucity of high-level evidence in the literature.MethodsA systematic review and meta-analysis was conducted. Two independent reviewers were used. Pooled proportions and numbers needed to screen were calculated. A cost per life year model was generated based on varying survival benefits and compared to other Canadian screening programs to provide financial context.ResultsSix studies (n = 3772 patients) were included. Of the 3772 patients, 3751 had a pre-operative clinical and post-operative pathological diagnosis of inflammatory nasal polyps. Agreement proportion was 99.44 %. There were 18 unexpected benign and three unexpected malignant diagnoses identified. This translated to a proportion of 0.48 and 0.08 % respectively. Number needed to screen was 210 and 1258 respectively. Pooled proportion for expected findings using a random effect model was 0.99 (95 % CI = 0.99–1). Pooled proportion for unexpected benign findings using a random effect model was 0.00522 (95 % CI = 0.00133–0.01). Pooled proportion for unexpected malignant findings using a random effect model was 0.00107 (95 % CI = 0.000147–0.00283). The cost to pick up one unexpected benign diagnosis was $14557.2. The cost to pick up 1 unexpected malignant diagnosis was $87204.56. Cost per quality life year calculated ranged from 3211.83 to $64677.58 based on varying assumptions on the survival benefits of identifying an unexpected malignancy.ConclusionsRoutine pathological examination in screening for neoplasia may be low yield, however, no compelling evidence was found to cease such practice. Surgeons should exercise individual judgment in requesting routine examination.Electronic supplementary materialThe online version of this article (doi:10.1186/s40463-015-0100-8) contains supplementary material, which is available to authorized users.
Objectives Extended endoscopic approaches are useful for resection of selected craniopharyngiomas. Midline, extraventricular, and predominantly cystic lesions are good candidates for endoscopic resection. In this video, we demonstrate the endoscopic endonasal resection of a large suprasellar craniopharyngioma and discuss the nuances of the surgical technique. Design/Setting Surgical video of an extended endoscopic approach for resection of a suprasellar craniopharyngioma.Results We report the case of a 56-year-old woman who presented with bitemporal hemianopsia and visual acuity deterioration secondary to a large suprasellar solid-cystic lesion. The patient underwent an extended endoscopic transtuberculum approach for resection of the lesion, which was diagnosed as a papillary craniopharyngioma. This video discusses the anatomy and surgical technique applied for endoscopic resection of such lesions. Conclusion Endoscopic endonasal surgery is a useful technique for management of craniopharyngiomas. It is associated with good clinical outcomes in selected cases. Complications, such as postoperative CSF leak, may occur and should be carefully managed. The link to the video can be found at: https://youtu.be/EneOCiQE7yo.
