AbstractAccumulating evidence points to pachychoroid possibly being caused by vortex vein congestion which results in remodeling of choroidal drainage routes via intervortex vein anastomosis. This hypothesis prompted us to investigate vortex vein hemodynamics by studying videos of indocyanine green angiography (ICGA) in a retrospective case series of 295 eyes with pachychoroid spectrum diseases. In the early phase of the video-ICGA, pulsatile vortex venous flow was observed in 76 eyes (25.8%) at the vortex veins connected with anastomosis between superior and inferior vortex veins. The patients with pulsatile vortex venous flow were significantly older than those without pulsatile vortex venous flow (67.8 ± 13.2 vs. 63.9 ± 14.5 years, P < 0.05). Pulsatile vortex venous flow was 1.84 times more common in the inferior quadrants than in the superior quadrants. Interestingly, 14 of 76 eyes (18.4%) with pulsatile vortex venous flow showed retrograde pulsatile blood flow in the vortex veins. This retrograde pulsatile blood flow was 2.50 times more common in the inferior than in the superior quadrants. These findings indicate altered vortex vein hemodynamics due to vortex vein congestion in pachychoroid spectrum diseases.

Background Critically ill children presenting to district general hospitals (DGH) are admitted to adult intensive care units (AICUs) for stabilisation prior to transfer to paediatric intensive care units (PICUs). Current training in PICU for adult intensive care physicians is only three months. This single centre retrospective case series examines the case mix of children presenting to a DGH AICU and a multidisciplinary survey assesses confidence and previous experience, highlighting continued training needs for DGH AICU staff. Methods all paediatric admissions to AICU and paediatric retrievals were reviewed over a 6-year period (2014-2019). Cases were identified from the Electronic Patient Record (EPR) and from data provided by the regional paediatric retrieval service. A questionnaire survey was sent to AICU doctors and nurses to assess confidence and competence in paediatric critical care. Results Between 2014-2019, 284 children were managed by AICU. In total 35% of cases were <1 y, 48% of cases were <2 y and 64% of cases were <5 y, and 166/284 (58%) children were retrieved. Retrieval reduced with increasing age (OR 0.49 [0.40-0.60], p < 0.0001). The survey had an 82% response rate, and highlighted that only 13% of AICU nurses and 50% of doctors had received prior PICU training. Conclusion At least one critically unwell child presents to the AICU each week. Assessment, stabilisation and management of critically unwell children are vital skills for DGH AICU staff, but confidence and competence are lacking. Formalised strategies are required to develop and maintain paediatric competencies for AICU doctors and nurses.
