Treatment and Management of Upper Extremity Dysfunction Following Transradial Percutaneous Coronary Intervention: A Prospective Cohort Study

Le résumé fourni par la source

BACKGROUND: The transradial artery access is the benchmark approach in transradial percutaneous coronary intervention (TR-PCI). The purpose of this study was to evaluate the different complications, treatments, and outcome of upper extremity dysfunction following a TR-PCI. METHODS: This was a prospective cohort substudy of patients with access-site complications. The study population consisted of 433 patients treated with TR-PCI. Referral to the hand center was mandated if the patient experienced new-onset or increase of preexistent symptoms in the upper extremity. Patients were followed up to the last control visit (5-7 months after the index procedure) at the hand center. Outcome results were categorized in "symptom-free," "improvement of symptoms," and "no improvement." RESULTS: Forty-one (9% of total) patients underwent assessment at the hand center. Most frequent referral indication was pain in the intervention arm. Women, preexisting sensibility disorder, and osteoarthritis in the intervention arm were associated with increased odds of referral. The most common complications diagnosed were carpal tunnel syndrome (n = 18) and osteoarthritis (n = 15). Thirty patients required further medical treatment. Immobilization therapy was most applied. Seventeen (4% of total) patients had persisting symptoms despite medical treatment. CONCLUSIONS: The occurrence of complications in the upper extremity after a TR-PCI is small. Despite medical treatment, symptoms persisted in 4% of all patients treated with TR-PCI. Possible explanations for the persisting symptoms are exacerbation of latent osteoarthritis and carpal tunnel syndrome by trauma-induced edema. Awareness of TR-PCI-induced complications among all specialists is essential to optimize patient care.
