Safety of Bronchoscopy in Patients with Echocardiographic Evidence of Pulmonary Hypertension

Background: Bronchoscopy with transbronchial and endobronchial biopsy and transbronchial needle aspiration is an important diagnostic tool in the pulmonologist's armamentarium. Safety in patients with pulmonary hypertension is controversial and many bronchoscopists consider this as a contraindication for the procedure. Objectives: To evaluate safety of bronchoscopy in patients with echocardiographic pulmonary hypertension and to compare with patients without it. Methods: Retrospective analysis of patients who underwent bronchoscopic transbronchial biopsy, endobronchial biopsy and/or endobronchial ultrasound-guided transbronchial needle aspiration. Patients were divided into two groups based on echocardiographic results: control group with systolic pulmonary artery pressure Results: One-hundred and ninety patients met the study criteria. Patients in the control group were younger with a lower incidence of chronic kidney disease. There was no difference in prevalence of congestive heart failure, obstructive airway disease, malignancy, liver disease, coagulopathy, use of antiplatelet agent or anticoagulant drugs. Incidence of minor bleeding due to bronchoscopic biopsies was 4.8% in both groups (p = 1.00). Incidence of major bleeding was similar in the groups (one patient in each group). In the control group, one patient had pneumothorax and another required prolonged mechanical ventilation (>4 h). In the eSPAP group, two patients required prolonged mechanical ventilation. There was no procedure-related mortality or sedation complications in the cohort. Conclusion: Our study provides additional support that in patients with echocardiographic evidence of pulmonary hypertension, transbronchial and endobronchial biopsies and endobronchial ultrasound-guided transbronchial needle aspiration are safe procedures.
