Background and purpose: Spina bifida is the second major cause of congenital disorders and the most common central nervous system congenital malformation compatible with life primarily. Herein, we describe the short-term outcome of post-natal Myelomeningocele (MMC) surgical management and predictors of its postoperative complications and mortality.
Methods: This retrospective chart review studies the children who underwent post-natal surgical management for MMC in Namazi hospital, a tertiary referral center, in southern Iran from May 2001 to September 2020.
Results: 248 patients were included in this study. The mean age at the operation was 8.47 ± 8.69 days. The most common site of involvement of MMC was Lumbosacral (86%, n = 204). At the evaluation conducted prior to the operation, cerebrospinal fluid leak was observed in 7% (n=16) of the patients. Postoperatively, 5.7% of the patients expired in the 30-day follow-up after the operation (n = 14), while 24% needed readmission (n = 47). The most common complications leading to readmission were wound dehiscence (n = 10, 42%) and wound purulence (n = 6, 25%). Only the site of the lesion (p-value = 0.035) was associated with postoperative complication. After controlling for potential confounders, the site of the lesion (adjusted odds ratio = 0.146, 95% confidence interval = 0.035-0.610, p-value = 0.008) and age at surgery (adjusted odds ratio = 1.048, 95% confidence interval = 1.002-1.096, p-value = 0.041) were significantly associated with mortality CONCLUSIONS: The age of the patients at the surgery and the site of the lesion are the two factors that were associated with mortality. However, further investigations into preoperative interventions and risk factors to mitigate the risk of complications and mortality are highly encouraged.
