Experience with Ambulatory Management of Pleural Pathologies Utilizing Small-Bore Indwelling Pleural Catheters

Introduction Pleural effusion is the excess fluid that accumulates in the pleural space. Pneumothorax is the collection of free air in the pleural cavity, while empyema is the collection of pus in the pleural cavity. Such pleural pathologies pose a great challenge to patients and health care professionals alike. While multiple management options exist, the major portion of it is carried out in the inpatient setting. We sought to evaluate the ambulatory use of indwelling pleural catheters for pleural pathologies, including malignant pleural effusion, empyema, and primary spontaneous pneumothorax. Methods We conducted a prospective case series analysis of 15 patients with various pleural pathologies in which an indwelling pleural catheter was placed by interventional radiologists on an outpatient basis and subsequently followed-up in a pulmonary clinic. Results were analyzed on the basis of clinical, as well as radiological progress with parameters being complete, partial, or no resolution. We also obtained prospective data on the quality of life of these patients. Results Six out of seven patients with malignant pleural effusion reported clinical (complete or partial) resolution, while three reported radiological (complete or partial) resolution. Two of the three patients with nonmalignant pleural effusions reported complete clinical as well as radiological resolution. All three patients with empyema reported complete clinical resolution and partial radiological resolution, while both patients with primary spontaneous pneumothorax reported complete clinical and radiological resolution. Patients reported preserved or improved quality of life with the whole process managed on an outpatient basis. Conclusion We report a high rate of clinical and radiological resolution in various pleural pathologies in our study, which is first of its kind from this part of the world. It demonstrates the feasibility of ambulatory management of pleural pathologies with a multidisciplinary approach.
