PURPOSE
We aimed to determine the safety and feasibility of transradial access (TRA) in bronchial artery and  non-bronchial systemic artery (NBSA) embolization in patients with non-massive hemoptysis.

METHODS
This retrospective study was approved by the Institutional Review Board. Among the 300 patients treated for hemoptysis with bronchial artery and NBSA embolization between April 2018 and July 2019, 19 procedures in 19 patients were conducted by TRA and were retrospectively analyzed. TRA was considered when the bronchial artery or NBSA originated from the arch vessel or its tributaries. The exclusion criteria of TRA included Barbeau C or D waveform and a radial artery diameter of less than 1.8 mm on ultrasound. TRA was also avoided in cases of the high-origin bronchial artery (i.e., T4 or higher level of the aorta). The hemoptysis-free time was estimated using the Kaplan–Meier method.

RESULTS
The technical success (i.e., embolization of all target artery with TRA) rate was 94.7% (18 out of 19 patients). In terms of the target arteries, embolization with TRA was technically successful in treating 47 out of 48 arteries (97.9%). The 1-month and 6-month hemoptysis-free rates were 89.5% (17/19) and 73.7% (14/19), respectively. The only adverse event was iatrogenic dissection of the bronchial artery with little clinical significance in 1 patient. No access site complications were identified on post-procedure day 1 ultrasonography.

CONCLUSION
With proper patient selection, TRA offers a safe and effective approach to embolize the bronchial arteries and NBSAs in patients with hemoptysis.
