PURPOSE: Pneumothorax (PTX) following cardiac implantable electronic device procedures is traditionally treated with chest tube drainage (CTD). We hypothesized that, in a subset of patients, the less invasive needle aspiration (NA) may also be effective. We compared the strategy of primary NA with that of primary CTD in a single-center observational study.
METHODS: Of the 970 procedures with subclavian venous access between January 2016 and June 2018, 23 patients had PTX requiring intervention. Beginning with March 2017, the traditional primary CTD (9 cases) has been replaced by the "NA first" strategy (14 patients). Outcome measures were procedural success rate and duration of hospitalization evaluated both as time to event (log-rank test) and as a discrete variable (Wilcoxon-Mann-Whitney test).
RESULTS: Needle aspiration was successful in 8/14 (57.1%) of the cases (95% CI 28.9-82.3%), whereas PTX resolved in all patients after CTD was 9/9 (100%, 95% CI 66.4-100.0%, p = 0.0481). Regarding length of hospital stay, intention to treat time to event analysis showed no difference between the two approaches (p = 0.73). Also, the median difference was not statistically significant (- 2.0 days, p = 0.17). In contrast, per protocol evaluation revealed reduced risk of prolonged hospitalization for NA patients (p = 0.0025) with a median difference of - 4.0 days (p = 0.0012). Failure of NA did not result in a meaningful delay in discharge timing as median difference was 1.5 days (p = 0.28).
CONCLUSIONS: Our data suggest that in a number of patients iatrogenic PTX may be successfully treated with NA resulting in shorter hospitalization without the risk of meaningful discharge delay in unsuccessful cases.
