A groundbreaking fetoscopic laser procedure offers new hope for twins facing severe complications.
The Fetal Medicine Team at Posadas Hospital has successfully performed an innovative procedure on a high-risk pregnancy. This life-saving technique, known as fetal laser photocoagulation by fetoscopy, was utilized for a woman carrying twins wiht a serious condition.
The pregnancy involved a biamniotic,monocorial twin gestation. This means the twins shared a placenta, leading to a condition called fetofetal transfusion syndrome adn selective growth restriction.
Fetofetal transfusion syndrome is a grave complication where an unequal blood flow exchange occurs between the shared placenta of twins.This unequal distribution significantly endangers both fetuses, with a mortality risk as high as 90% for both.
Adding to the complexity, the pregnancy also faced selective growth restriction. In this scenario, one fetus fails to grow adequately due to an insufficient placental share.
The fetal laser photocoagulation procedure is a minimally invasive intervention. It effectively works by sealing the abnormal vascular connections between the fetuses within the placenta.
This sealing process aims to restore balanced blood flow, thereby improving the chances of survival and healthy development for both twins.
During the procedure, guided by ultrasound, a fetoscope and a laser fiber are inserted into the uterine cavity. this allows direct visualization of the placenta.
The medical team can then precisely identify and coagulate the specific vessels responsible for the blood transfusion between the fetuses. This targeted approach minimizes disruption to the surrounding structures.
Dr. Sayago, a specialist in Fetal Medicine and coordinator of the Fetal Surgery Team at Posadas Hospital, highlighted the advancements in the technique. He noted that previously, procedures required draining large amounts of amniotic fluid, which could damage the membrane separating the fetuses and complicate treatment.
He also mentioned that along with Dr. sergio Cruz Díaz, they perform approximately seven such interventions annually. Patients from across the country seek this specialized treatment at the hospital, establishing it as a national reference point.
In this particular case, the laser photocoagulation was performed at 23 weeks of gestation.The twins were subsequently born healthy at 32 weeks gestation. After nearly two months of care in the neonatology unit, they have now been discharged, a testament to the success of this pioneering intervention.

Frequently Asked Questions
-
What is fetofetal transfusion syndrome?
It is a complication in twin pregnancies where fetuses share a placenta, leading to an unequal exchange of blood, which can be life-threatening for both.
-
What is fetal laser photocoagulation by fetoscopy?
It is a minimally invasive fetal surgery where a laser is used to seal abnormal blood vessel connections in the placenta between twins, guided by a fetoscope and ultrasound.
-
What is selective growth restriction?
This occurs when one fetus in a pregnancy stops growing due to an inadequate share of the placenta or placental function.
What are the specific risks associated with monochorionic twin pregnancies that necessitate advanced surgical interventions like those performed at Posadas Hospital?

Understanding the Complexity of Twin Pregnancies
Twin pregnancies, while joyous, present unique challenges compared to singleton pregnancies. These challenges increase the risk of complications for both the mother and the babies. Common concerns include preterm labor, preeclampsia, gestational diabetes, and twin-twin transfusion syndrome (TTTS). Advanced surgical interventions are sometimes necessary to improve outcomes, and Posadas Hospital has recently demonstrated leadership in this area. This article will delve into the specifics of a groundbreaking surgery performed at Posadas Hospital,focusing on the techniques used,the benefits for twin pregnancies,and what this means for the future of maternal-fetal care. We’ll cover topics like monochorionic twin pregnancies, selective fetal reduction, and fetoscopic surgery.
The Pioneering Surgery: A Detailed Look
Posadas Hospital recently completed a complex surgical procedure on a mother carrying monochorionic twins – twins sharing a single placenta.This situation carries a considerably higher risk of TTTS, a condition where one twin receives too much blood flow while the other receives too little. The surgery, a elegant form of fetoscopic laser ablation, targeted the abnormal blood vessel connections within the placenta causing the imbalance.
HereS a breakdown of the procedure:
- Fetoscopic Access: A tiny camera and surgical instruments are inserted through small incisions in the mother’s abdomen.
- Precise Laser Ablation: Using the fetoscope, surgeons precisely target and seal off the abnormal blood vessels feeding the affected twin. This redirects blood flow to create a more balanced circulation.
- real-time Monitoring: throughout the procedure, fetal heart rates and placental blood flow are continuously monitored to ensure the safety of both twins.
- Post-operative Care: Close monitoring of the mother and babies is crucial after the surgery, including frequent ultrasounds to assess fetal well-being and placental function.
This surgery represents a notable advancement in the treatment of TTTS and other monochorionic twin complications. The precision offered by fetoscopic techniques minimizes trauma to the fetuses and maximizes the chances of a positive outcome.
monochorionic Twin Pregnancies: A Higher Risk Profile
Monochorionic twins, representing approximately 25-30% of all twin pregnancies, are at a substantially increased risk of complications. Understanding these risks is crucial for proactive management:
Twin-Twin Transfusion Syndrome (TTTS): As mentioned, this is the most serious complication, occurring in 10-15% of monochorionic pregnancies.
Selective Intrauterine Growth Restriction (sIUGR): One twin may grow significantly slower than the other due to unequal placental sharing.
twin Anemia-Polycythemia Sequence (TAPS): A slower, more chronic form of blood imbalance than TTTS.
Congenital anomalies: A slightly higher incidence of birth defects is observed in monochorionic twins.
Early and consistent prenatal care, including specialized monitoring with frequent ultrasounds, is paramount in managing these pregnancies.
Benefits of Fetoscopic Surgery in Twin Pregnancies
fetoscopic surgery offers several advantages over traditional management strategies for intricate monochorionic pregnancies:
Improved Survival Rates: For TTTS, fetoscopic laser ablation has significantly improved the survival rate for both twins.
Reduced Neurological Morbidity: By correcting the blood flow imbalance, the risk of long-term neurological damage in the affected twins is reduced.
Minimally Invasive: Compared to open fetal surgery, fetoscopic techniques are less invasive, resulting in faster maternal recovery and reduced risk of complications.
Targeted Treatment: The procedure allows for precise targeting of the problematic blood vessels, minimizing damage to healthy placental tissue.
Potential to Delay Delivery: Prosperous surgery can sometimes allow the pregnancy to continue for a longer period, improving fetal maturity.
Posadas Hospital’s Expertise in Maternal-Fetal Surgery
Posadas Hospital has established itself as a leading center for maternal-fetal surgery in the region.Their team comprises highly skilled obstetricians,fetal surgeons,neonatologists,and supporting staff dedicated to providing comprehensive care for high-risk pregnancies. The hospital’s investment in advanced technology, including state-of-the-art fetoscopic equipment, allows them to perform these complex procedures with a high degree of precision and safety.
The hospital’s commitment extends beyond the surgical intervention itself. They offer comprehensive pre- and post-operative counseling, genetic testing, and long-term follow-up care for families affected by twin pregnancies.
Selective Fetal Reduction: A Challenging but Sometimes Necessary Option
While the focus is on preserving both twins, in some cases of severe complications, selective fetal reduction* may be considered. This is a deeply personal and ethically challenging decision, involving the reduction of one twin to improve the chances of survival for the other. Posadas Hospital provides compassionate and comprehensive counseling for families facing this difficult choice, ensuring they have all the information needed to make an informed decision. This is typically considered in cases of severe sIUGR or when one twin has a life-limiting condition.
