ABSTRACT

PURPOSE: We examined the association between progesterone (P4), estradiol (E2), and human chorionic gonadotropin (hCG) levels in early pregnancy and the development of hypertensive diseases of pregnancy among women undergoing assisted reproduction. METHODS: Retrospective study including patients who underwent frozen embryo transfer (FET), ovarian stimulation (OS), or unassisted conception (UC) and had a live singleton birth. The primary outcome was the development of hypertensive diseases of pregnancy (gestational hypertension, preeclampsia, HELLP, or eclampsia). Secondary outcomes were the development of fetal intrauterine growth restriction (IUGR), gestational diabetes mellitus, birth weight, and pre-term birth. Hormone levels and the development of the outcomes were correlated. RESULTS: A total of 681 patients were included; 189 had FET, 193 had OS, and 299 had UC. Patients undergoing FET or OS were not more likely to develop hypertensive diseases of pregnancy compared with UC patients. While median levels of E2 and P4 were significantly different between P-FET and NC-FET patients (E2: 252 vs 317 pg/mL, P4: 64 vs 29 ng/mL, respectively; both p < 0.01), rates of hypertensive diseases of pregnancy did not significantly differ between those two groups. In the multivariate analyses, P4, E2, and hCG were not associated with the development of hypertensive diseases of pregnancy, but progesterone levels were significantly higher among those with IUGR. This remained consistent when the analysis was limited to FET patients. CONCLUSION: P4, E2, and hCG levels did not correlate with the development of hypertensive diseases of pregnancy but elevated progesterone levels did correlate with the development of IUGR.

ABSTRACT

INTRODUCTION: As reconstructive surgeons have increasingly transitioned to the prepectoral plane for prosthetic breast reconstruction, the implications of mastectomy skin flap necrosis have become more concerning. Our goal was to evaluate the effect of skin flap necrosis on reconstructive outcomes in patients undergoing immediate prepectoral breast reconstruction. METHODS: A retrospective review was conducted of patients undergoing immediate two-stage prepectoral reconstruction at a single center with at least 3 months follow-up. Postoperative complications, reconstructive outcome, and time to final implant were compared between patients with and without mastectomy skin necrosis. RESULTS: A total of 301 patients underwent 509 prepectoral breast reconstructions. Forty-four patients (14.6%) experienced postoperative mastectomy skin flap necrosis. Demographic and reconstructive characteristics were similar between the necrosis and no necrosis cohorts. Patients with skin necrosis were more likely to undergo reoperation after tissue expander (64% vs 19%, p < 0.01) and undergo expander replacement (13.6% vs 3.5%, p = 0.02). However, rates of reconstructive failure (6.8% vs 6.2%), major infection (9.1% vs 9.0%), and minor infection (13.6% vs 17.5%) after expander placement were statistically similar. Patients with skin necrosis trended toward longer time before final implant placement, although the difference was not statistically significant (6.5 vs 5.0 months, p = 0.08). There was no difference in complication rates between the necrosis and no necrosis cohort after final implant placement. There was a higher rate of revision surgery after implant placement in the necrosis cohort (12.5% vs 4.1%, p = 0.047). CONCLUSIONS: Mastectomy skin flap necrosis is a concerning postoperative event, particularly in patients with prepectoral prostheses. We observed that patients with skin necrosis experience higher reoperation rates in the expander period, yet have similar infection rates and achieve similar final reconstructive outcomes compared to patients without necrosis.
