title: Transradial access for visceral endovascular interventions in morbidly obese patients: safety and feasibility.
abstract: OBJECTIVE
  Transradial access (TRA) has been shown to lower morbidity and bleeding complications compared to transfemoral access in percutaneous coronary interventions. Morbid obesity, commonly defined as a body mass index (BMI) ≥40 kg/m2, has been shown to be a risk factor for access site complications irrespective of access site. This study evaluates the safety and feasibility of performing visceral endovascular interventions in morbidly obese patients via TRA.
  
  
  METHODS
  Procedural details, technical success, and 30-day major and minor access site, bleeding, and neurological adverse events were prospectively recorded in a database of 1057 procedures performed via the radial artery. From this database we identified 22 visceral interventions performed with TRA in 17 morbidly obese patients (age: 53 ± 11 years, female: 71%) with a median BMI of 42.7 kg/m2.
  
  
  RESULTS
  Interventions included radio-embolization (n = 7, 31.8%), chemo-embolization (n = 6, 27.3%), uterine fibroid embolization (n = 4, 18.2%), renal embolization (n = 2, 9.1%), hepatic embolization (n = 1, 4.5%), lumbar artery embolization (n = 1, 4.5%), and renal angioplasty (n = 1, 4.5%). The technical success was 100%. There were no major or minor adverse access site, bleeding, or neurological complications at 30 days.
  
  
  CONCLUSIONS
  This study suggests visceral endovascular interventions performed in morbidly obese patients are safe and feasible.
