Key result
Paclitaxel-coated balloon via distal transradial access maintains chronic radial artery patency at 14 months.
Why the study?
Chronic radial artery occlusion after transradial PCI presents a clinical challenge for subsequent interventions and treatment options are not well established.
Does paclitaxel-coated balloon angioplasty via distal transradial access restore patency in patients with chronic radial artery occlusion?
Case Report (n=1)
No
Does paclitaxel-coated balloon angioplasty via distal transradial access restore patency in patients with chronic radial artery occlusion?
Treatment of chronic radial artery occlusion with a paclitaxel-coated balloon via distal transradial access successfully restored and maintained radial artery patency up to 14 months.
May support paclitaxel-coated balloon use via distal access for chronic radial artery occlusion; hypothesis-generating and requires prospective confirmation.
A 38-year-old male patient was diagnosed as acute non-ST-segment elevation myocardial infarction on Apr 21st 2021 and he received percutaneous transluminal coronary angioplasty for RCA via transradial artery access. He sought for second percutaneous coronary intervention in our center for frequently exertional angina on Sep 13th 2021. Proximal right radial artery pulsation can not be touched in physical examination, indicating right radial artery occlusion (RAO). Distal transradial access was applied and RAO was confirmed via angiography. With balloon pre-dilation, the guidewire and guiding catheter crossed the occlusion and coronary intervention was successfully completed. A Reewarm 2.5 × 220 mm paclitaxel drug-coated balloon (Endovastec, China) was released at 12 atm in radial arterial lesion with 90 s. Pulsation of radial artery can be well palpated 24 h after PCI. No oral anticoagulant was added. The right radial artery remained patent after 8-month and 14-month follow-up and there was no abnormal sensation or obstacle of right hand.

Liu et al. (2023) conducted a case report in Chronic radial artery occlusion (n=1). Paclitaxel drug-coated balloon (Reewarm 2.5 × 220 mm) was evaluated on Radial artery patency. Treatment of chronic radial artery occlusion using a paclitaxel-coated balloon via distal transradial access successfully maintained radial artery patency at 14-month follow-up.
