About 30 days after TPD placement, the patient attended the clinic with dyspnea on minimal effort (visual analog scale [VAS]: 8/10, modified Medical Research Council dyspnea grade: III), with ineffective TPD draining. Chest X-ray revealed grade II/IV right pleural effusion, unchanged from previous studies, with the catheter placed correctly in the right hemithorax.
