Summary

This study found that taking aspirin does not increase the risk of bleeding after transbronchial lung biopsy. The overall risk of severe bleeding following this procedure is less than 1%.

Background:

Transbronchial lung biopsy (TBLB) is a common procedure for diagnosing lung conditions.
Aspirin is frequently used for cardiovascular prevention, raising concerns about bleeding risk with invasive procedures.

Purpose of the Study:

To investigate whether aspirin use increases the risk of bleeding complications following transbronchial lung biopsy.

Main Methods:

A prospective cohort study included 1,217 patients undergoing TBLB.
Patients were divided into two groups: those taking aspirin within 24 hours of the procedure and a control group.
Bleeding incidence was compared between the groups, with aspirin use not being discontinued.

Main Results:

Related Experiment Videos

Overall bleeding occurred in 4.7% of patients, with no significant difference between aspirin users (1.8% minor, 1.1% moderate, 0.9% major) and controls (2.9% minor, 1.4% moderate, 0.8% major).
Severe bleeding events were rare (<1%) in both groups.
All bleeding was managed endoscopically, with no fatalities or need for blood transfusions.

Conclusions:

Aspirin use is not associated with an increased risk of bleeding after transbronchial lung biopsy.
The risk of severe bleeding following TBLB is low, suggesting aspirin can be continued peri-procedure.
