UNASSIGNED: A retrospective chart review was performed to identify all patients with a body mass index (BMI) greater than or equal to 30 kg/m2 who underwent breast reconstruction between the years 2013 to 2020 with saline implants filled beyond the manufacturer\'s maximum recommended volume.
UNASSIGNED: The 21 patients identified had an average age of 49 years. The mean BMI was 39.5 kg/m2. A total of 42 implants were placed; 34 were 800 mL, 4 were 750 mL, and 4 were 700 mL. The average overfill volume was 302 mL (138%). Mean follow-up was 65.0 months. Of these, 1 (4.8%) patient with a history of chest wall radiotherapy underwent reoperation for unilateral implant exposure 27 days after the index procedure, no patient sustained spontaneous leak or rupture, and 1 patient had unilateral deflation following emergent central line and pacemaker placement 2 years after the implant was placed for an unrelated cardiovascular event.
UNASSIGNED: Hyperinflation of saline implants beyond the maximum recommended volume may be considered for volume replacement in obese patients undergoing implant-based breast reconstruction. This practice is well tolerated, has a complication rate comparable to using implants filled to the recommended volume, and has the potential to restore lost breast volume in the obese patient post mastectomy.
UNASSIGNED:进行回顾性图表审查,以确定所有体重指数(BMI)大于或等于30kg/m2的患者,在2013年至2020年之间进行了乳房重建,并填充了超过制造商最大推荐体积的盐水植入物。
未经证实:确定的21名患者平均年龄为49岁。平均BMI为39.5kg/m2。总共放置了42个植入物;34个是800毫升,4是750mL,和4个为700mL。平均溢出体积为302mL(138%)。平均随访65.0个月。其中,1例(4.8%)有胸壁放疗史的患者在索引程序后27天接受了单侧植入物暴露的再次手术,没有患者持续自发性渗漏或破裂,1例患者在置入植入物2年后紧急放置中心线和起搏器后出现单侧放气,原因是无关的心血管事件。
UNASSIGNED:在接受基于植入物的乳房重建的肥胖患者中,可以考虑对超过最大推荐体积的盐水植入物进行过度充气,以进行体积置换。这种做法是可以容忍的,并发症发生率与使用填充到推荐体积的植入物相当,并有可能恢复乳房切除术后肥胖患者失去的乳房体积。
