Pregnancy Following Breast Reconstruction with TRAM Flaps

Pregnancy Reverses Abdominoplasty Aesthetic Outcome: Myth or Misconception? A Cross-Sectional Study

BACKGROUND

The common recommendation for female abdominoplasty candidates is to conclude family planning before undergoing the procedure. However, no evidence demonstrates a correlation between aesthetic outcome compromise, risk for fetal complications, or risk for maternal complications when abdominoplasty is followed by pregnancy.

OBJECTIVES

The aim of this study was to evaluate maternal, fetal, and aesthetic outcomes among pregnant females with a history of abdominoplasty.

METHODS

The authors conducted an online survey among women who became pregnant after having an abdominoplasty. Participants were recruited via social media groups related to abdominoplasty. The survey included demographic-, aesthetic outcome-, and pregnancy-related questions utilizing a score from 1 (no effect) to 10 (worst effect) to assess abdominal aesthetic outcome compromise.

RESULTS

Thirty-two participants completed the online survey, 15 (46.8%) of which reported their pregnancy was unplanned. Pregnancy-related findings included 5 (15.6%) late premature births (between gestational week 35 and 37), 1 miscarriage, and 1 emergency C-section. Compromised aesthetic outcomes following pregnancy included new abdominal stretch marks (50%, N = 16), widened abdominoplasty scar (28%, N = 9), abdominal skin excess (37.5%, N = 12), and abdominal bulge (25.8%, N = 8). A new hernia was reported by 2 participants (6.3%). The average abdominal aesthetic severity score was 2.7 (range, 1-8), and only 3 scores were above 5 (9.3%). Two women (6.2%) underwent abdominoplasty revision, and 18 (56.2%) stated they would recommend others to undergo abdominoplasty before pregnancy (56.3%).

CONCLUSIONS

This survey shows there is room to reevaluate whether future pregnancy should be considered a relative contraindication for undergoing abdominoplasty.

Is Pregnancy Following a TRAM or DIEP Flap Safe? A Critical Systematic Review and Meta-analysis

BACKGROUND

Previous data were not conclusive on the safety of gestation in patients whose abdominal flaps were earlier harvested. We performed a meta-analysis to evaluate the abdominal wall complications and birth mode of pregnancy in post-TRAM or post-DIEP harvested individuals.

METHODS

A literature search was performed using the PubMed, Embase, Scopus, and Google scholar database. Heterogeneity was statistically analyzed, and random effect models were applied. Publication bias was assessed by funnel plot.

RESULTS

We included 25 papers that captured 56 patients giving birth to 69 healthy babies after elevation of abdominally based flaps, with a pooled abdominal complication rate of 0.00-0.09. The complication incidence in TRAM group was 0.01 (95% CI = [0.00-0.14%]) while 0.00 in the DIEP group (95% CI = [0.00-0.26%]). Discrepancies in incidence following unilaterally or bilaterally based TRAM flaps, following free or pedicled TRAM flaps, following primary sutured or mesh strengthened fascia, following MS free TRAM or conventional free TRAM could not be calculated as statistically significant. TRAM group and DIEP group patients had identical birth modes.

CONCLUSIONS

The present meta-analysis did not detect evidence that abdominal walls with the prior harvest of abdominal flaps could affect the process of pregnancy or contraindicate vaginal delivery. No abdominal hernia or bulge occurred with post-DIEP pregnancies. However, such conclusions need to be substantiated by larger sample studies.

Does Pregnancy Predict Incisional Hernia Repair after Abdominally Based Autologous Breast Reconstruction? A Retrospective Review of 890 Free Flaps

BACKGROUND

The abdomen is a common donor site in autologous breast reconstruction. The authors aimed to determine whether pregnancy following autologous breast reconstruction increases the risk of incisional hernia repair.

METHODS

All women younger than 50 years who underwent abdominally based autologous breast reconstruction between 2005 and 2016 were identified. Patients with less than 20 months of follow-up were excluded. Demographics, operative details, outcomes, incisional hernia repair occurrence, and pregnancy history were analyzed.

RESULTS

Five hundred nineteen patients underwent autologous breast reconstruction with 890 free flaps [free transverse rectus abdominis musculocutaneous, n = 645 (72.5 percent); deep inferior epigastric perforator, n = 214 (24.0 percent); pedicled transverse rectus abdominis musculocutaneous, n = 18 (2.0 percent); and superficial inferior epigastric artery, n = 13 (1.5 percent)]. Average follow-up was 57.2 months (range, 9.5 to 312.8 months). Fourteen women became pregnant, with mean postpregnancy follow-up of 31.2 months (range, 5.4 to 70.8 months; pregnancies, n = 18). Age of nonpregnant patients (mean, 43.1 years; range, 20.6 to 50.0 years) was higher than that of pregnant patients (mean, 32.1 years; range, 27.1 to 37.9 years) (p < 0.0001); in univariate analysis, age was not associated with incisional hernia repair. Twelve pregnant patients (66.7 percent) underwent cesarean delivery. No statistically significant differences existed between groups regarding flap type and closure technique. Zero pregnant patients underwent incisional hernia repair, compared with a 6.1 percent incisional hernia repair rate in nonpregnant patients (p = 0.339). In multivariate analysis, prior incisional hernia, hematoma, fascial dehiscence, and reoperation predicted incisional hernia repair.

CONCLUSION

The authors' results demonstrate that there may not be an increased risk of incisional hernia repair associated with pregnancy following autologous breast reconstruction despite additional weakening of the abdominal wall.

Pregnancy following Unilateral Immediate Breast Reconstruction with Titanized Polypropylene Mesh (TiLOOP(R) Bra) without Compromising the Result

Immediate breast reconstruction after mastectomy due to cancer or as a prophylactic treatment is widely preferred to avoid psychosocial distress, poor body image, and diminished sexual well-being. An increasing number of women undergoing breast reconstruction are in childbearing age; however, only limited data are available on the cosmetic outcome of patients undergoing implant-based breast reconstruction with a surgical mesh and subsequent pregnancy. This is a case report of a female patient who underwent unilateral implant-based breast reconstruction with a titanized surgical mesh implant (TiLOOP Bra). Twenty-two months after reconstruction, the woman delivered a healthy child. No adverse events occurred. The patient breastfed with the contralateral breast. The cosmetic result and patient-reported outcome was excellent. Pregnancy after breast reconstruction with a synthetic surgical mesh is not contradictory to an excellent cosmetic outcome.

Systematic review of effects of pregnancy on breast and abdominal contour after TRAM/DIEP breast reconstruction in breast cancer survivors

Transverse rectus abdominis myocutaneous (TRAM) and its derivatives are the most commonly performed autologous breast reconstruction procedures. These procedures were not recommended in the past for those who planned for subsequent childbearing because of the transposition of portions of the abdominal wall during the procedure into the anatomic position of the breast, implying possible adverse effects over the contour of these manipulated areas during pregnancy and delivery. We conducted a systematic review to assess the literature on esthetic or functional consequences of childbearing over the breast and abdomen after these procedures in patients that were affected by breast cancer. A comprehensive literature search in databases and citation indexes was conducted from February 2014 to April 2015. Any paper on pregnancy after breast reconstruction by TRAM or its derivatives and modifications, written in English or French, were included. The search results underwent a first screening to exclude duplicate and irrelevant papers. Full texts were then reviewed as to the criteria for inclusion, and data were extracted into data extraction forms from eligible papers. The initial search yielded 5132 articles. After screening and review, overall 17 papers met all criteria for inclusion in this review. Our work revealed that uneventful pregnancy and delivery can be anticipated in breast cancer survivors who had undergone breast reconstruction via TRAM or its derivatives with minor negative effects on either the breast or the abdomen.

Successful pregnancy "during" pedicled transverse rectus abdominis musculocutaneous flap for breast reconstruction with normal vaginal delivery

A transverse rectus abdominis myocutaneous (TRAM) flap is a popular choice for breast reconstruction. Pregnancies in women following a TRAM flap present concerns regarding both safety and the integrity of the abdominal wall. We report a case of a patient who was pregnant during immediate breast reconstruction with pedicled TRAM flap and had a successful spontaneous vaginal delivery. We also conducted a literature review using PubMed on pregnancy post TRAM flap, type of reconstruction, timing of pregnancy after TRAM flap, complication, and mode of delivery, which are summarised in this report. We concluded that patients may have safe pregnancies and normal deliveries following TRAM flap breast reconstruction regardless of the time frame of pregnancy after the procedure. Therefore, TRAM flaps can continue to be a reconstruction option, even in women of childbearing age.
