Transarterial Embolization Via Radial Artery Access In Patients With Cancer-related Bleeding

Purpose:To investigate the outcomes of transarterial embolization(TAE)using the radial artery access for the treatment of cancer-related bleeding.Materials and Methords:Data of 26 patients[mean age,53.8± 10.6 years;male,n=14(53.8%)]who underwent TAE for cancer-related bleeding using the radial artery access at our institution between July 2018 and March 2019 were retrospectively reviewed.Of these,seven patients(26.93%)had vaginal bleeding,six(23.1%)had hemoptysis,six(23.1%)had upper gastrointestinal bleeding,three(11.5%)had lower gastrointestinal bleeding,three(11.5%)had intraabdominal bleeding,and one(3.8%)had oronasal bleeding.Cervical cancer[n=7,(26.9%)]were the most common causes of bleeding followed by lung cancer[n=6,(23.1%)].Results:Technical success was achieved in 24 patients(92.3%)with a median procedure time of 49(range,18-89)minutes.Two patients(7.7%)had to crossover to the right femoral artery access due to the left subclavian artery tortuosity(n=1)and the radial artery spasm(RAS)(n=1).Eight patients(30.8%)had rebleeding within 30 days after the procedure.The 30-day bleeding-related were 7.7%(2/26).Two patients(7.7%)had minor complications(RAS,n=1;postembolization syndrome,n=1).No major complications were encounteredConclusion:Radial artery may be used as the primary access for TAE with high technical success rate and low complication rates in patients with cancer-related bleeding.
