Abstract： Objective To discuss the surgical management of cavernous malformation (CM) in medulla oblongata with dyspnea after hemorrhage.Methods The clinical data of four patients with CM in medulla oblongata with dyspnea after hemorrhage were analyzed retrospectively.The mean preoperative Karnofsky Performance Scale (KPS) was 17.5.All of the patients underwent operation through posterior midline suboccipital approach.Results Complete resection was achieved in four patients.The main clinical symptoms of dyspnea, facial paralysis and pain were totally improved.But there was no change of motor deficits or sensory disturbance.The mean postoperative KPS was 60.Two patients were improved and others were stabilized.The mean follow - up duration was 15.0 months without recurrent hemorrhage.The recent mean KPS was 70.Conclusions Patients with CM in medulla oblongata suffering from dyspnea could obtain favorable prognosis through surgical treatment.
