Summary
Surgical separation of craniopagus twins was deemed impossible due to a shared venous system. The twins received conservative treatment, prioritizing their quality of life.
Area of Science:
- Neurosurgery
- Pediatric Surgery
- Vascular Surgery
Background:
- Craniopagus twins present complex surgical challenges, requiring extensive multidisciplinary evaluation.
- This case involves Suriname female occipito-parietal to occipito-parieto-temporal conjoined twins.
Observation:
- The twins underwent comprehensive diagnostic assessments, including advanced imaging like 3D-CT, MRI, MRA, and cerebral angiography with balloon occlusion tests.
- A multidisciplinary team evaluated the feasibility and ethical considerations of surgical separation.
Findings:
- A shared venous ring with preferential drainage to one twin was identified.
- Endovascular balloon occlusion tests confirmed the inability to safely separate the shared venous system.
- Surgical separation was deemed impossible without significant risk of neurological damage or compromising quality of life.
Implications:
- This case highlights the critical role of advanced vascular imaging and testing in surgical planning for craniopagus twins.
- Conservative management, respecting parental wishes, was chosen as the optimal approach when surgical separation is not feasible.
- The findings underscore the complex interplay between vascular anatomy, surgical risk, and ethical decision-making in conjoined twin cases.
