Transradial peripheral vascular intervention using Fowler's position and Terumo R2P system for patients with heart failure: two case reports.

backgroundPositioning a patient on the catheterization table is important for proper cardiac or respiratory function during peripheral vascular interventions. Fowler's position, where the patient's head is a 45° angle, is more effective in reducing venous blood volume returning to the heart from the periphery compared with the supine position. The Terumo R2P system has been developed for transradial peripheral vascular interventions. CASE PRESENTATION: Two patients with heart failure (a 75-year-old Japanese female and a 74-year-old Japanese male) underwent lower-extremity peripheral vascular interventions in Fowler's position to prevent worsening heart failure. Because their head position was opposite the C-arm of the X-ray machine, the left radial artery was selected as the access site. The Terumo R2P system was used for transradial peripheral vascular intervention. We successfully treated superficial artery diseases with long shaft balloons and rapid-exchange Terumo R2P Misago stents.

conclusionsAlthough lower-extremity peripheral vascular intervention using Fowler's position and the Terumo R2P system has several limitations, including device availability and technical complexity, it may be effective for particular patients who have higher risk of worsening heart failure in the supine position.
