    Introduction: Pulmonary Artery Sarcomas are rare and aggressive vascular tumors, which are often misdiagnosed and managed as pulmonary thromboembolic disease until an alternate diagnosis is suspected due to lack of response to anticoagulants.This may result in delayed treatment until histological confirmation.
Methods: We present a patient with a filling defect at the left pulmonary artery which was biopsied with EBUS-TBNA and revealed intimal pulmonary sarcoma.
Results: Male, 34 years-old, with a history of hepatic sarcoma at the age of 10, heterozygote for thalassemia and G6PD deficiency, presented to our Interventional pulmonology department with hemoptysis, fatigue and dyspnea on exertion 3 months prior to admission. His chest CT revealed a large intraluminal low attenuation filling defect at the level of the left pulmonary artery. Following, chest MRI confirmed the presence of a large endovascular tumor of the left PA. With the aid of endobronchial ultrasound, the vascular tumor was successfully located (10L position), observed and sampled by endobronchial ultrasound (EBUS) transbronchial needle aspiration (TBNA) with a 22G needle.Tissue biopsy revealed an intimal sarcoma of the pulmonary artery.The patient was referred and had a successful surgical excision.
Conclusion: Bronchoscopy and EBUS-TBNA may play an important role in the rare pathologies of the mediastinal vasculature adjacent to the airways through transbronchial-transvascular approach.

Introduction: High Flow Nasal Cannula oxygenation method is effective in oxygenation of patients with respiratory failure and has shown clinical benefits over Low Flow Nasal Cannula.
Objective: We performed a metanalysis to evaluate the potential favorable impact of the High Flow Nasal Cannula oxygenation during bronchoscopy and related procedures like EBUS-TBNA.
Methods: Eight studies with 488 patients have been included in this metanalysis, after screening a bulk of 144 studies. All these studies met quality criteria as defined by ROB-2 tool l to evaluate the risk of bias in the included randomized controlled studies and ROBINS-I tool for non-randomized studies.
Results: Patients that underwent bronchoscopy (EBUS and/or Fiberoptic bronchoscopy) with the use of High Flow Nasal Cannula experienced less hypoxemic events/desaturations compared to patients under Low Flow Nasal Cannula treatment (O.R.= 0.24; 95% CI= 0.16,0.37; p<0.01; I2= 71%). Desaturation events were lower using HFNC whether FOB +/- BAL or Biopsy was performed (O.R.=0.36; 95% CI= 0.2,0.65; p<0.01; I2 = 83%) or EBUS-TBNA (O.R.=0.15; 95% CI= 0.08,0.30; p<0.01; I2 = 0%).
Conclusion: This abstract shows that that High Flow Nasal Cannula oxygen therapy might more effective compared to Low Flow Nasal Cannula therapy in reducing hypoxemic events during bronchoscopy, especially during EBUS-TBNA.
