Abstract | BACKGROUND AND IMPORTANCE: The decompressive hemicraniectomy (DCH) after malignant middle cerebral artery infarction in children is a rare procedure, and the indication is discussed as being controversial. Etiological Moyamoya disease has some additional challenges concerning the therapeutic strategy that have not mentioned in the recent literature, as it is dependent on special pathophysiology. CLINICAL PRESENTATION: We report a case of a four-year-old patient with a decompressive hemicraniectomy after malignant middle cerebral artery infarction on the right hemisphere based on a Moyamoya syndrome with proximal MCA occlusions on both sides. After the decompression there was a good restitution of the hemiparesis, aphasia, and consciousness loss on admission. The bone flap replacement is usually done after three month in our department to ensure brain swelling has subsided. In this patient the cranioplasty was not arranged because of the development of collateral vessels to the right motor region through the craniotomy defect, to protect the supply of the eloquent cortex. CONCLUSION: We conclude that the indication of DCH and postoperative treatment should be discussed individually, especially when neovascularisation developments can occur like in Moyamoya disease. An important point is the right timing for bone flap replacement, which should be directly after cerebral edema has subsided prior to the evolution of collaterals through the craniotomy defect. Additionally, leaving the opportunity for neovascularization through smaller defects has to be taken into account.
