Risk factors for haemoptysis after percutaneous transthoracic needle biopsies in 4,172 cases: Focusing on the effects of enlarged main pulmonary artery diameter

To evaluate the risk factors for haemoptysis after cone-beam computed tomography (CBCT)-guided percutaneous transthoracic needle biopsy (PTNB), particularly on whether the enlargement of main pulmonary artery diameter (mPAD) is a risk factor for PTNB-related haemoptysis.
4,172 cases of CBCT-guided PTNBs in 3,840 patients were retrospectively included in this study. Various data including mPAD measured on preprocedural CT images were evaluated using logistic regression analyses to determine significant risk factors for both haemoptysis and severe haemoptysis, designated as when blood transfusion, vascular embolisation or cardiopulmonary resuscitation were required to manage patients with haemoptysis.
Haemoptysis occurred in 5.78 % (241/4172) of all PTNB procedures, while severe haemoptysis occurred in 0.18 % (7/4172). Female sex, history of antiplatelet or anticoagulative drugs, prolonged activated partial thromboplastin time, subsolid nodules, cavitary nodules and long pleura-to-target distance were revealed to be independent risk factors for haemoptysis, while mPAD enlargement (> 29.5 mm) was not. Regarding severe haemoptysis, however, mPAD enlargement was demonstrated to be an independent risk factor along with the presence of subsolid and cavitary target nodules.
mPAD enlargement was not a significant risk factor for PTNB-related haemoptysis; however, it was a significant risk factor for severe haemoptysis.
• mPAD enlargement was a significant risk factor for severe PTNB-related haemoptysis.
• mPAD can be useful in screening high-risk patients for severe haemoptysis.
• Subsolid or cavitary nodule was another significant risk factor for severe haemoptysis.

Study subjects or cohorts overlap
Among our study population, 42.8 % (1,787 out of 4,172 patients) were reported in previous publications (Lee SM, Park CM, Lee KH, Bahn YE, Kim JI, Goo JM (2014) Radiology 271:291-300 and Kim JI, Park CM, Lee SM, Goo JM (2015) Eur Radiol 25:1845-1853). However, those previous studies dealt with different topics to the current paper. One of those studies (Lee SM et al) evaluated the diagnostic accuracy of CBCT-guided PTNBs and complication rates in general and the other paper (Kim JI et al) dealt with the usefulness of rapid needle-out-patient-rollover manoeuvre with respect to the reduction of the occurrence of pneumothorax and its drainage catheter placement.
