The Neurosurgery & Spine team at Nam Sai Gon International General Hospital has recently applied advanced magnetic field–guided Navigation technology in the surgical treatment of hemorrhagic stroke, achieving successful outcomes in critical cases.
The patient, Mr. C.N., a 51-year-old Cambodian national, was rushed to the hospital after suddenly developing slurred speech and left-sided weakness. He was first stabilized at a local hospital before being transferred to Nam Sai Gon International General Hospital. Initial neurological assessments and a contrast-enhanced CT scan confirmed the diagnosis: intracerebral hemorrhage involving the right thalamus and internal capsule with intraventricular extension, caused by underlying idiopathic hypertension.
Given the critical condition and the deep location of the hematoma, the surgical team decided to proceed with minimally invasive hematoma drainage guided by a magnetic field–based Navigation system — a cutting-edge technology recently adopted at the hospital.
“With this method, we only need to drill a small burr hole in the skull”, explained Dr. Vu. “Thanks to the magnetic navigation system, we can guide the drainage catheter precisely into the hematoma and the ventricle. This allows us to administer thrombolytic agents and safely drain the blood. Compared to traditional optical-navigation systems, magnetic field navigation has the major advantage of being less susceptible to disruption by objects in the operating room. Because magnetic fields can penetrate and operate in multiple directions, the procedure is both faster and more accurate”.
Over the following days, the patient was closely monitored in the hospital’s intensive care unit. “Given the patient’s serious condition upon arrival, we had to monitor him very carefully postoperatively to catch any possible complications early”, shared Dr. Anh. “After four days of drainage, the hematoma was almost completely cleared. By the tenth day, his condition had stabilized — he was able to engage in simple communication and was discharged to continue rehabilitation at home”.
The doctors emphasized the importance of postoperative care and secondary stroke prevention. The patient’s family was instructed to maintain a low-sodium diet, closely monitor blood pressure, and arrange for physical therapy at a local facility to help improve muscle strength and mobility on the affected side.
Hemorrhagic stroke is most commonly caused by uncontrolled hypertension. Symptoms can appear suddenly and require immediate emergency care. If not treated promptly, patients are at risk of permanent neurological damage or death. Early intervention, combined with modern technology like magnetic field–guided Navigation, can significantly improve treatment outcomes.
To reduce the risk of hemorrhagic stroke, patients with hypertension should follow a healthy lifestyle, regularly monitor their blood pressure, and attend routine check-ups to detect abnormalities early.
