Gestar

What Gestar does

Gestar Centro de Medicina e Cirurgia Fetal is a specialized fetal medicine and intrauterine surgery clinic headquartered in São Paulo, Brazil. It provides a comprehensive portfolio of advanced prenatal diagnostic services (morphological ultrasound at first and second trimester with Doppler, fetal echocardiography with 3D/4D techniques, fetal biophysical profiling, cardiotocography, amniocentesis, chorionic villus sampling, cordocentesis, and thoracentesis) and intrauterine surgical interventions (myelomeningocele repair via a proprietary 2.5 cm mini-hysterotomy technique, fetoscopic laser ablation for twin-twin transfusion syndrome and selective fetal growth restriction, fetoscopic tracheal occlusion for severe congenital diaphragmatic hernia, endoscopic urethral valve destruction, thoraco-amniotic and nephro-amniotic drain placement, intrauterine blood transfusion, and experimental third ventriculostomy).

The practice is led by Dr. Cleisson Fábio Andrioli Peralta, an obstetrician and fetal surgeon trained at King's College Hospital London, supported by a team of 9 subspecialists covering maternal-fetal medicine, fetal echocardiography, general and vascular ultrasound, and endometriosis imaging. Surgical procedures are performed at affiliated hospitals including Hospital do Coração (HCOR), Hospital São Luiz, Hospital Santa Marcelina, and CETRUS. The practice coordinates the Rede Gestar de Medicina Materno-Fetal network and the postgraduate fetal medicine training program at CETRUS.

Gestar operates a direct-to-consumer and physician-referral model, generating revenue from per-consultation and per-procedure professional services billed to patients or insurers. Patients reach the practice via obstetrician referrals, hospital affiliations, national media exposure of the lead surgeon (Fantástico, CNN Brasil), a dedicated WhatsApp direct line, and individual physician booking pages on the clinicadigital.tisaude.com platform. The website's fetal surgery counter currently reads zero, indicating either recent reset or limited public tracking of surgical volume. No external investment, funding rounds, or parent company ownership is disclosed; the practice appears to be a physician-led collaborative group.

Products and services

• Mielomeningocele (MMC) / Spina Bifida Correction Surgery Open fetal surgery to correct myelomeningocele (spina bifida) via a modified mini-hysterotomy technique (2.5 cm incision), reducing maternal risks and preterm birth compared to the standard MOMs trial technique, performed between 19-26 weeks gestation.
• Twin-Twin Transfusion Syndrome (TTTS) Laser Ablation Fetoscopic laser ablation surgery to cauterize communicating placental vessels in twin-twin transfusion syndrome, lasting approximately 60 minutes under spinal anesthesia, with an 80% chance of at least one twin surviving.
• High Urinary Tract Obstruction - Nephro-Amniotic Drain Placement Placement of nephro-amniotic drains to allow fetal urine to exit and accumulate in the amniotic sac, improving lung development and survival from 0% to 50% in cases of high-grade fetal urinary obstruction.
• Low Urinary Tract Obstruction - Endoscopic Urethral Valve Destruction Endoscopic surgery using a balloon catheter to rupture the posterior urethral valve membrane and dilate the urethra in male fetuses with lower urinary tract obstruction, performed at under 26 weeks gestation.
• Fetal Anemia - Intrauterine Blood Transfusion (Cordocentesis) Intravascular blood transfusion directly into the fetal umbilical cord for treatment of moderate to severe fetal anemia (PVS > 1.5 MoM), performed between 18-34 weeks, with 70-90% fetal survival rates.
• Congenital Diaphragmatic Hernia - Fetal Tracheal Occlusion (FETO) Fetoscopic endoluminal tracheal occlusion with balloon placement to promote fetal lung expansion in severe congenital diaphragmatic hernia, improving survival from 10% to 50%, followed by balloon removal at 32-34 weeks.
• Fetal Pleural Effusion - Thoraco-Amniotic Drain Placement Placement of thoraco-amniotic drains to drain accumulated fluid from the fetal pleural cavity in cases of fetal pleural effusion, improving perinatal survival from 25% to 70% when accompanied by hydrops.
• TRAP Sequence - Laser Interruption of Placental Vessels Laser interruption of blood flow between the normal fetus and the acardiac twin in TRAP sequence, increasing the chance of the normal fetus surviving to 76%.
• Selective Fetal Growth Restriction Surgery Laser ablation of placental vessels to separate the circulation of fetuses with selective intrauterine growth restriction and severe blood flow alterations (zero diastolic flow), protecting the larger fetus.
• Severe Cerebral Ventriculomegaly - Third Ventriculostomy Experimental fetal endoscopic third ventriculostomy under spinal anesthesia to perforate the floor of the third cerebral ventricle, draining accumulated cerebrospinal fluid to reduce hydrocephalus and brain damage.
• Congenital Cystic Adenomatoid Malformation (CCAM) - Thoraco-Amniotic Drain Thoraco-amniotic drain placement for cystic adenomatoid malformation of the lungs, draining pulmonary cysts to improve fetal lung development and survival to approximately 78%.
• Amniocentesis Collection of amniotic fluid for evaluation of fetal chromosome number and structure (fetal karyotype).
• Chorionic Villus Sampling Collection of placental tissue for evaluation of fetal chromosome number and structure (fetal karyotype).
• Cordocentesis Umbilical cord blood sampling for investigation of chromosomal anomalies, infections, anemia, and thrombocytopenia; also used to perform intrauterine blood transfusions and administer medications for specific cardiac rhythm abnormalities.
• Thoracentesis Pleural fluid collection from the fetal chest for diagnostic and therapeutic purposes, and drainage of cystic lung lesions, performed after 20 weeks gestation.
• First Trimester Morphological Ultrasound (Nuchal Translucency) First trimester morphological ultrasound / nuchal translucency examination performed between 11-13 weeks and 6 days to evaluate fetal anatomy, confirm gestational age, and calculate risks for chromosomal anomalies, preeclampsia, and intrauterine growth restriction.
• Second Trimester Morphological Ultrasound Second trimester morphological ultrasound examination performed between 18-24 weeks to assess fetal anatomy and growth, calculate risks for chromosomal anomalies, preeclampsia, and intrauterine growth restriction, with approximately 90% diagnostic accuracy.
• Obstetric Ultrasound with Doppler Obstetric ultrasound with Doppler evaluation to assess blood circulations between the fetus and placenta and between the mother and placenta, typically performed in the second half of pregnancy.
• Standard Obstetric Ultrasound Standard obstetric ultrasound to evaluate fetal anatomy, growth, position, and presentation, as well as amniotic fluid quantity, placental position, and characteristics.
• Fetal Echocardiography (Ecodopplercardiograma) Fetal echocardiography with Doppler and 3D imaging to identify and define anatomy and hemodynamic behavior of congenital heart defects, performed between 20-30 weeks (ideally around 28 weeks).
• Fetal Biophysical Profile Fetal well-being assessment combining ultrasound and cardiotocography to evaluate fetal tone, body movement, breathing movement, cardiac reactivity, and amniotic fluid volume, performed in the third trimester.
• Antepartum Cardiotocography Antepartum cardiotocography for fetal heart rate monitoring to assess fetal well-being.

Broad incumbents

• DASA (Diagnósticos da América): Largest medical diagnostics company in Latin America, operating imaging and laboratory networks including obstetric ultrasound. Competes with Gestar for prenatal diagnostic referrals in São Paulo through brands like Delboni and Alta.
• Hospital das Clínicas da FMUSP – Setor de Medicina Fetal: The largest academic public hospital in São Paulo, with a fetal medicine sector where several Gestar-affiliated physicians trained. Provides competing fetal diagnostic and surgical services to SUS patients and trains the next generation of specialists, overlapping with Gestar's pipeline.
• Fleury Medicina e Saúde: Brazil's largest diagnostic medicine company, offering obstetric ultrasound and prenatal diagnostics across São Paulo. Comparable on the diagnostic side of Gestar's business; not a fetal surgery competitor but competes for OB imaging referrals.
• Hospital Sírio-Libanês – Medicina Fetal: Another leading São Paulo private hospital offering specialized fetal medicine diagnostics and intrauterine procedures. Competes with Gestar for affluent high-risk pregnancy referrals, with the advantage of an integrated multi-specialty hospital system.
• Hospital Israelita Albert Einstein – Centro de Medicina Fetal: One of Brazil's most prestigious private hospital systems, Einstein operates a fetal medicine center in São Paulo offering advanced prenatal diagnostics and fetal surgery. It competes with Gestar for the same premium OB patient base but as part of a much broader tertiary hospital portfolio.

Regional players

• Maternidade Pro Matre Paulista: Major private maternity hospital in São Paulo with prenatal diagnostic and high-risk pregnancy services. Indirectly comparable as it serves the same high-risk OB patient pool in São Paulo, though it does not focus exclusively on fetal surgery.
• Hospital e Maternidade Santa Joana: Large private maternity hospital in São Paulo focused on high-risk pregnancies. Competes with Gestar for premium OB referrals and offers advanced ultrasound and fetal diagnostics, though it is less specialized in intrauterine surgery.

Direct peers

• Texas Children's Fetal Center: Major US-based fetal surgery and therapy center affiliated with Baylor College of Medicine. Performs the same set of intrauterine procedures as Gestar (myelomeningocele repair, TTTS, FETO, etc.) and serves as a benchmark for case volume and outcomes in the field.
• Children's Hospital of Philadelphia (CHOP) – Center for Fetal Diagnosis and Treatment: One of the world's leading fetal surgery centers, performing open and fetoscopic procedures including myelomeningocele repair, TTTS laser, FETO, and EXIT. A direct global peer in capability and case mix, though at a much larger scale.

Others

• Fetal Medicine Foundation: UK-based international body that certifies fetal medicine specialists and accredits ultrasound training programs. Gestar's lead physician holds the FMF international specialist title; FMF is an ecosystem/credentialing peer rather than a direct competitor.
