PURPOSE

To assess the effectiveness of tunneled pleural catheters (TPCs) in the treatment of malignant pleural effusions (MPEs).

MATERIALS AND METHODS

Twenty-eight patients with symptomatic MPEs had 31 hemithoraces treated with TPCs placed under image guidance. Chemical sclerotherapy had failed in two patients and two had symptomatic locules. Drainage was accomplished by intermittent connection to vacuum bottles. Pleurodesis was considered achieved when three consecutive outputs were scant and imaging showed no residual fluid.

RESULTS

All catheters were successfully placed. Dyspnea improved in 94% (29 of 31 hemithoraces) at 48 hours and 91% (20 of 22 patients) at 30 days. Control of the MPE was achieved in 90% of hemithoraces (28/31), although five required ancillary procedures. Pleurodesis occurred in 42% (13 of 31) of hemithoraces, including both that underwent an earlier attempt at chemical sclerotherapy and one treated locule. Continued drainage without pleurodesis controlled the effusion in 48% (15 of 31). In only 7% was hospital time necessary for care related to the TPC. Early, transient catheter-related pain was common, but only three complications (in two patients) occurred. Neither of these altered patient care.

CONCLUSIONS

Regardless of whether pleurodesis is achieved, TPCs provide effective long-term outpatient palliation of MPEs.

Patients

Over the course of 53 months, 28 patients with symptomatic MPEs were referred to the interventional radiology department for management of fluid with a long-term TPC that would be intermittently drained. Three patients had bilateral effusions treated in this manner, for a total of 31 hemithoraces. There were 13 men and 15 women. The mean age was 60 years, with a range of 31–85 years. The etiologies for the effusions were lung cancer in 10 patients (10 hemithoraces), melanoma in four patients

Technical Results

All catheters were successfully placed with no procedural complications. Three asymptomatic pneumothoraces were noted after catheter placement, which were small and occurred in patients with free-flowing effusions. All three resolved with just the normal drainage routine for the TPC.

Clinical Results

Follow-up time after placement of the catheters ranged from 3 to 618 days, with a median of 51 days. Patient survival was 86% at 2 weeks, 79% at 30 days, 52% at 60 days, and 48% at 90 days.

Improvement in dyspnea was

DISCUSSION

The accumulation of pleural fluid in patients with cancer may be a result of overproduction from disease involving the pleura, lymphatic obstruction, or atelectasis (1, 2, 3). Malignant pleural effusions are associated with significant morbidity, with the most common complaint being dyspnea. Other symptoms include cough, chest discomfort, and diminished quality of life (6). Especially when considering the limited life expectancy in most patients with MPE, prompt evaluation and treatment is

      Again, their design is very similar to that of the PleurX catheter, with a 16F soft silicone catheter, 40 cm in length with side holes over the distal 24 cm. Placement of IPCs is routinely an outpatient procedure,22 unless the patient is already admitted for another reason. The authors provide patients with teaching videos developed by the catheter manufacturer prior to their IPC placement so they can be more familiar and better prepared for handling these catheters.
