The patients received (radiofrequency catheter ablation) RFCA therapy for tachyarrhythmia have some differences to the patients in emergency stations and intensive care units, most of which don’t concomitant other diseases, and are physically in good condition, and catheters do not stay long in their bodies. There were few studies on the peumothorax during RFCA therapy for arrhythmia patients. We therefore conducted the retrospective study to determine the incidence and feature of the pneumothorax in these patients.
1021 subclavican-vein catheterizations that were performed in the procedures of RFCA using the Seldinger technique in our center were analyzed by retrospective investigation. The sex, age, weight, height, and body mass index (BMI; kg/m2) were investigated.
In total, 1021 procedures were analyzed, including 524 men and 497 women. A total of 7 patients experienced pneumothorax (7/1021; 0.7 %), all of which were women except of one boy with 13 years old. The differences between no pneumothorax group and pneumothorax group were not significant in age and weight (P >0.05), but the sex and BMI were statistically significant, with BMI was 21.4±1.6 in pneumothorax group, lower than no pneumothorax group (24.2±3.6, P <0.05).
Although patients accepted RFCA are physically in good condition and do not concomitant other diseases, they had the same incidence of pneumothorax in subclavian-vein catheterizations, compared to those in intensive units and emergency rooms, moreover, had more chances to develop delayed pneumothorax, and the patient’s sex and BMI contributed to the occurrence of the complication.
