[Using a pleural implantable access system for the management of malignant pleural effusions. Experience of Institut...

Malignant pleural effusion has a very poor prognosis, raises problems of medical management and impairs quality of life. The authors report the first experience of a pleural implantable access system for the treatment of recurrent symptomatic malignant pleural effusion.

Prospective follow-up of 26 patients between 20/8/2005 and 2/11/2006 in a single center. Thirty pleural implantable access systems were placed in 26 patients (22 patients with breast cancers, 3 bilateral placements and one case of replacement) under sedation following the decision of a multidisciplinary meeting.

Twenty-five patients obtained partial or complete relief of their dyspnea. Four patients underwent spontaneous pleurodesis after a maximum of 2 months. Twelve patients were receiving chemotherapy at the time of placement. The number of aspirations performed varied between 1 and 28 over a period of 11 to 330 days. Eight patients died within 1 month after placement of the system and 6 survived more than 6 months. Seven patients died at Institut Curie or in a palliative care unit without returning home. The other 16 patients presented a total of 198 days of hospitalization for 2,305 days of catheter implantation. No placement failures were observed in this series. Two infectious complications (infectious pleuro-pneumonia and skin infection over the puncture site) and two mechanical complications (expulsion of the port and disconnection between the port and the catheter) were observed and easily treated. One patient developed loculation of the pleural cavity after 16 thoracenteses making further thoracentesis ineffective.

The pleural implantable access system is an interesting alternative in terms of efficacy and safety for the outpatient management of malignant pleural effusion. It shows a number of advantages in terms of comfort and infectious risk compared to tunneled pleural catheters.
