A low-cost, time-efficient technique that could localize hypertensive hematomas in the basal ganglia would be beneficial for minimally invasive hematoma evacuation surgery. We used an iPhone to achieve this goal and evaluated its accuracy and feasibility.
We located basal ganglia hematomas in 26 patients and depicted the boundaries of the hematomas on the skin. To verify the accuracy of the drawn boundaries, computed tomography (CT) markers surrounding the depicted boundaries were attached to 10 patients. The deviation between the CT markers and the actual hematoma boundaries was then measured. In the other 16 patients, minimally invasive endoscopic hematoma evacuation surgery was performed according to the depicted hematoma boundary. The deflection angle of the actual trajectory and deviation in the hematoma center were measured according to the preoperative and postoperative CT data.
There were 40 CT markers placed on 10 patients. The mean deviation of these markers was 3.1 mm ± 2.4. In the 16 patients who received surgery, the deflection angle of the actual trajectory was 4.3° ± 2.1. The deviation in the hematoma center was 5.2 mm ± 2.6.
This new method can locate basal ganglia hematomas with a sufficient level of accuracy and is helpful for minimally invasive endoscopic hematoma evacuation surgery.
一种低成本、高效的技术能够定位基底节区高血压性血肿,这将有利于微创血肿清除手术。我们使用一部iPhone手机来实现这一目标,并评估其准确性和可行性。
我们对26例患者的基底节区血肿进行定位,并在皮肤上描绘出血肿边界。为验证所绘边界的准确性,对10例患者在描绘边界周围附着计算机断层扫描(CT)标记物。然后测量CT标记物与实际血肿边界之间的偏差。在另外16例患者中,根据所描绘的血肿边界进行微创内镜血肿清除手术。根据术前和术后CT数据测量实际轨迹的偏转角和血肿中心的偏差。
10例患者共放置了40个CT标记物。这些标记物的平均偏差为3.1 mm±2.4。在接受手术的16例患者中,实际轨迹的偏转角为4.3°±2.1。血肿中心的偏差为5.2 mm±2.6。
这种新方法能够以足够的精度定位基底节区血肿,有助于微创内镜血肿清除手术。
