Surgeons at Grupo Oroño in Rosario performed a combined emergency cesarean section and aortic dissection repair on a 42-year-old pregnant patient at 30 weeks gestation, marking the first time this complex cardiovascular procedure has been successfully executed in Argentina.
In Plain English: The Clinical Takeaway
- Aortic Dissection: A critical, life-threatening tear in the inner layer of the aorta—the body’s main artery carrying blood away from the heart.
- Marfan Syndrome: A rare genetic connective tissue disorder that weakens arterial walls, significantly raising the baseline risk of cardiovascular emergencies.
- Interdisciplinary Coordination: Simultaneous execution of a premature delivery and major vascular reconstruction by integrated specialist teams to preserve maternal and neonatal survival.
Emergency Admission at Sanatorio Parque
The patient presented to Sanatorio Parque reporting severe chest pain radiating directly into her back, a classic clinical indicator of acute aortic pathology. Diagnostic imaging confirmed a type of aortic dissection where the arterial tear extended from near the heart all down to the pelvis. The lesion actively compromised blood flow pathways supplying critical organs, including the brain and the right kidney.
Compounding the surgical challenge, the patient possessed a documented history of Marfan syndrome. Operating on an extensively dissected aorta during the third trimester of pregnancy requires balancing the hemodynamic stress of cardiopulmonary intervention against fetal viability.
Executing a Staged Operative Plan Across Hospitals
To address the dual threat, clinical leadership across Sanatorio Parque, Maternidad Oroño, and Sanatorio de Niños formulated a staged operative plan executed in immediate succession. Dr. Juan Pablo Pineda, an obstetrician at Maternidad Oroño, performed an emergency cesarean section. This extraction safely delivered the 30-week-old infant prior to initiating the primary cardiovascular intervention.
Immediately following the delivery, Dr. José Luis Sgrosso, a cardiovascular surgeon at Sanatorio Parque, assumed control of the sterile field to reconstruct the ruptured maternal vessel. The surgical team excised the compromised aortic tissue, replacing the entire damaged segment with a synthetic vascular prosthesis. This synthetic graft restores structural containment of arterial pressure, preventing fatal hemorrhage or visceral malperfusion.
Intensive Care Recovery and Neonatal Progress
Following the multi-hour procedure, the patient was transferred to the intensive care unit for continuous hemodynamic monitoring and blood pressure stabilization. Her postoperative recovery progressed without major complications, enabling hospital discharge just eight days after the operation.
The newborn was admitted immediately to the neonatology service at Sanatorio de Niños to manage complications associated with premature birth at 30 weeks. After receiving specialized respiratory and developmental support, the infant achieved clinical stability and was discharged into outpatient monitoring under the institution’s specialized neonatal follow-up team.
Demanding Specialized Preconception Counseling During Pregnancy
Pregnancy in individuals with Marfan syndrome demands specialized preconception counseling and high-risk obstetric monitoring due to the exponential rise in wall stress during the third trimester.
Multidisciplinary Integration in High-Risk Obstetrics
Managing acute type A or extensive aortic dissections during advanced pregnancy remains exceptionally rare in global clinical literature. The success of this intervention relied entirely on the rapid diagnostic synchronization of cardiology, cardiovascular surgery, obstetric, anesthesiologic, intensive care, and neonatology teams working within an integrated healthcare network.
