“…Ectopic BAs originating from the thyrocervical trunk are rare. Summarizing several studies on MDCT angiography (Michimoto et al 2020;Hartmann et al 2007;Battal et al 2011;Yener et al 2015), only 9 of 624 patients (1.4%) had BAs originating from the thyrocervical trunk. This rate was lower than those of the subclavian (29/624; 4.6%) or internal mammary (11/624; 1.8%) artery origin.…”

“…BAs originating apart from between the T5 and T6 vertebrae are considered ectopic, and the incidence of ectopicity has been reported to range from 8.3% to 36% (Michimoto et al 2020). Ectopic BAs can be distinguished from NBSAs by their course along the major bronchi.…”

“…Many studies have reported that MDCT angiography not only has the ability to identify the source of bleeding and the underlying disease of hemoptysis, but also precisely detect the origins and courses of culprit arteries before BAE, which is especially advantageous for visualizing the ectopic origin of BAs and NBSAs, which are easily missed by conventional angiography during BAE (Zhao et al 2017;Li et al 2019;Lorenz et al 2012;Michimoto et al 2020;Panda et al 2017). Li et al (2019) suggested that preprocedural MDCT angiography can reduce the recurrence rate of hemoptysis after BAE, and recommended MDCT angiography as a routine examination before BAE in patients with hemoptysis as far as possible.…”

Background: Ectopic bronchial artery and non-bronchial systemic arteries may be the culprit vessels of hemoptysis. The main cause of clinical failure of bronchial artery embolization is incomplete embolization caused by the misidentification of the culprit arteries by conventional angiography. Multidetector computed tomography angiography is useful for visualizing the culprit arteries. Case presentation: An 82-year-old man was admitted with hemoptysis. Preprocedural multidetector computed tomography angiography revealed an ectopic bronchial artery branching from the right thyrocervical trunk. Superselective embolization of the ectopic bronchial artery was performed using gelatin sponge particles and metallic coils. Hemoptysis was controlled by this procedure without any associated complications. Conclusions: Ectopic bronchial arteries originating from the thyrocervical trunk are rare. Preprocedural multidetector computed tomography angiography is useful for visualizing the culprit arteries of hemoptysis, especially if a patient has an ectopic bronchial artery or an ectopic non-bronchial systemic artery.
