[How to manage late periprosthetic fluid collections (seromas) in patients with breast implants?].

The widespread use of silicone implants in reconstructive and aesthetic breast surgery led to an increase in the incidence of breast implant associated anaplastic large cell lymphoma, BIA-ALCL, mainly associated with the use of macro-textured breast implants. BIA-ALCL is a serious complication presenting clinically as a late onset periprosthetic seroma. Thus, its occurrence became an alarming sign feared by most plastic surgeons. Therefore, a good knowledge with respect to early diagnosis, subsequent workup, and treatment is crucial in the management of periprosthetic seroma. The diagnosis of late onset seroma is clinically evident. Although idiopathic seroma is the most common cause, BIA-ALCL should be always eliminated. A complete workup is usually necessary. An ultrasound performed by a radiologist specialized in breast imaging followed by an ultrasound guided puncture is imperative. Consequently, the cytological and the bacteriological analysis will orient us toward the etiology (infectious, neoplastic or mechanical). A standardized management of late periprosthetic seroma does not exist, with various factors are to be taken into consideration. These include the surgeon's experience, the diagnosis, and the medical institution facilities. Although idiopathic seroma is managed by a simple puncture and drainage, other causes may require a surgical procedure with implant removal, capsulotomies, and/or total capsulectomies.
