STROBE—Radiation Ulcer

Abstract

With increasing numbers of percutaneous coronary intervention (PCI) and complex cardiac procedures, higher accumulated radiation dose in patient has been observed. We speculate cardiac catheter intervention induced radiation skin damage is no longer rare.To study the incidence of cardiac fluoroscopic intervention induced radiation ulcer.We retrospectively reviewed medical records of those who received cardiac fluoroscopic intervention in our hospital during 2012 to 2013 for any events of radiation ulcer. Only patients, whose clinical photos were available for reviewing, would be included for further evaluation. The diagnosis of radiation ulcers were made when there is a history of PCI with pictures proven skin ulcers, which presented typical characteristics of radiation injury.Nine patients with radiation ulcer were identified and the incidence was 0.34% (9/2570) per practice and 0.42% (9/2124) per patient. Prolonged procedure time, cumulative multiple procedures, right coronary artery occlusion with chronic total occlusion, obesity, and diabetes are frequent characteristics. The onset interval between the first skin manifestation and the latest radiation exposure varied from 3 weeks to 3 months. The histopathology studies failed to make diagnosis correctly in 5 out of 6 patients. To make thing worse, skin biopsy exacerbated the preexisting radiation dermatitis. Notably, all radiation ulcers were refractory to conventional wound care. Surgical intervention was necessary to heal the wound.Diagnosis of cardiac fluoroscopy intervention induced radiation skin damage is challenging and needs high index of clinical suspicion. Minimizing the radiation exposure by using new approaches is the most important way to prevent this complication. Patient education and a routine postprocedure dermatology follow up are mandatory in high-risk groups for both radiation skin damage and malignancies.This is a retrospective study, thus the true incidence of radiation ulcer caused by cardiac fluoroscopic intervention could be higher.

Risk Factors For Radiation-Induced Skin Ulceration in Percutaneous Coronary Interventions of Chronic Total Occluded Lesions: A 2-Year Observational Study

“…This study is the first to recruit patients with RSU events to explore the relationship between PCI-related variables and RSU events. We previously emphasized the overlooked RSU events and presented their clinical pictures 13 . The RSU events always occurred a few weeks or months after prolonged PCIs.…”

“…The RSU events always occurred a few weeks or months after prolonged PCIs. Iatrogenic skin complications are usually overlooked and underreported by physicians because the skin lesions do not become apparent until months after the PCIs 6 , 13 , 14 . A meta-analysis of 2857 CTO PCI procedures analysed from 65 studies reported only three cases with radiation-induced skin injury 6 .…”

Management of fluoroscopy-induced radiation ulcer: One-stage radical excision and immediate reconstruction

“…This may relate to the complexity or repetitive courses required to achieve acceptable cardiac outcomes. Recently, we noticed an increasing incidence of severe radiation dermatitis in our hospital 4 . Moreover, the trend is worldwide 5 6 7 8 9 10 11 12 13 .…”

Radiation-Induced Skin Injuries to Patients: What the Interventional Radiologist Needs to Know

“…The incidence of radiation-induced ulcers is not as rare as previously assumed [25]. Radiation-induced skin ulcer is a consequence of an excessively high cumulative skin dose.…”
