Microcatheter Arterial Thrombectomy Surgery
Ischemic stroke occurs when cerebral blood vessels are obstructed by a thrombus or blood clot, preventing blood flow and resulting in “ischemia” in brain tissue. Small vessel occlusion accounts for 37.8% of cases, while large vessel occlusion represents approximately 27.6%.
Historically, treatment methods primarily involved the administration of thrombolytic drugs, which must be given within 4.5 hours of stroke onset. However, the effectiveness of these treatments diminishes for clots that obstruct large vessels. With advancements in catheter technology, it is now possible to remove clots blocking cerebral blood vessels through minimally invasive techniques, thereby restoring blood flow. Health insurance may cover the associated surgical costs.
Treating a stroke requires prompt action. The symptoms of a stroke can be summarized using the acronym FAST:
- Facial Drooping: When the patient smiles, the two sides of the face appear asymmetrical.
- Arm Weakness: When the patient raises both arms forward, one side is unable to lift or maintain the position.
- Speech Difficulties: The patient may slur their words or be unable to speak clearly.
If any of these three symptoms are present, the likelihood of a stroke is high, and immediate medical attention is essential.
It is important to note the time of onset. If the onset time is uncertain, record the last time the patient was observed to be in a stable condition.
3D Stereotactic Navigation Surgery: Enhancing Precision in Brain Surgery
Neurosurgery specializes in a range of minimally invasive procedures for the brain and spine and has long been recognized for its high-quality services. To enhance the safety of brain surgeries, advanced navigation equipment and various surgical room devices have been integrated, significantly improving both the quality and safety of these procedures.
The navigation surgery system inputs the patient’s preoperative images and examination data into a computer, which reconstructs and simulates this information for preoperative registration. During the preparation and execution of the surgery, a probe is utilized for positioning, enabling the display of the current anatomical location.
Guided by the navigation system, surgeons can more accurately identify lesions, resulting in more precise incision sites, smaller surgical wounds, and reduced damage to surrounding tissues and nerves, thereby enhancing surgical safety.
