3D lung volume measurements seem to be useful in the prenatal prediction of PH.

Background Spontaneous pneumothorax has been reported as a possibile complication of novel coronavirus associated pneumonia (COVID-19). We report two cases of COVID-19 patients who developed spontaeous and recurrent pneumothorax as a presenting symptom, treated with surgical procedure. An insight on pathological finding is given. Case presentation Two patients presented to our hospital with spontaneous pneumothorax associated with Sars-Cov2 infection onset. After initial conservative treatment with chest drain, both patients had a recurrence of pneumothorax during COVI-19 disease, contralateral (patient 1) or ipsilateral (patient 2) and therefore underwent lung surgery with thoracoscopy and bullectomy. Intraoperative findings of COVID-19 pneumonia were parenchymal atelectasis and vascular congestion. Lung tissue was very frail and prone to bleeding. Histological examination showed interstitial infiltration of lymphocytes and plasma cells, as seen in non specific interstitial pneumonia, together with myo-intimal thicknening of vessels with blood extravasation and microthrombi. Conclusions Although rarely, COVID-19 may present with spontaneous pneumothorax. Lung surgery for pneumothorax in COVID-19 patients can be safely and effectively performed when necessary.

Short oral presentation abstracts MPA T2, with a trend towards a correlation between fetal DO2 and PBF, as shown in Figure 1. Conclusions: We demonstrated a relationship between fetal oxygen delivery and pulmonary blood flow in the late gestation fetus. Reduced pulmonary blood flow and changes in the branch pulmonary artery flow velocity waveform may be early signs of fetal hypoxia, occurring prior to changes in MCA PI.
