ABSTRACT
Objective To evaluate the therapeutic effects of Lumber continued drainage of cerebrospinal fluid after Key-hole approach operation and craniotomic hematoma elimination on the prognosis of hypertensive in-tracerebral hemorrhage patients. Methods Lumber continued drainage of cerebrospinal fluid after Key-hole ap-proach operation was conducted on 38 hypertensive intracerebral hemorrhage patients. At the 1st month and 6th month after operation, Glasgow coma scale (GCS), Glasgow outcome scale (GOS), Barthel index, language barrier degree evaluation and sports function barrier degree evaluation were measured. The therapeutic effects were observed and compared with 34 patients who were operated by craniotomic hematoma elimination. Results GCS was 6.8± 2.1,6.6±2.3 before operation and 10.5±2.5,8.7±2.2 one week after operation in experimental group and con-trol group respectively; GOS was 3.4±0.3,2.8±0.2 one month after operation and 4.1±0.6,3.2±0.4 six month after operation in experimental group and control group respectively; Bartherl index, language barrier degree and sports function barrier degree were 63.15±11.64,51.76±12.81 and 1.7±0.3,2.3±0.2,2.0±0.3, and 2.6± 0.4 (P<0.05 or P<0.01). Conclusion Lumber continued drainage of cerebrospinal fluid after Key-hole approach operation offers greater help in improving the patients' quality of existence, by which the neurological function recov-ers faster and the patients recover well.
ABSTRACT
Objective To study the endoscopic anatomy of operative fissures in the sellar region related to pterional key-hole approach and to provide the anatomic basis for endoscope-assisted microneuro-surgery in the region. Methods Fifteen cadaver heads were dissected via pterional key-hole approach and the five operative fissures(Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ) were studied with both microscope and endoscope, by which the outcomes observed were recorded and compared. Results The basic information obtained by the pterio-nalkeyhole approach was comparable to that of the classic ptefional approach. According to the anatomic guideposts under neuroendoscope, the microstructures of the five fissures and Willis' circle would be well demonstrated. It is better to display the various anatomic structures in sellar region by neuroendoscope rather than microscope, particularly some important microstructures. Angled endoscope can be used to inspec thidden but important structure behind the arteries and nerves. Conclusion According to the anatomic guideposts, an endoscopy can be used to enhance the visible field of an operative microscope related to pterional key-hole approach. The endoscope-assisted microsurgery can reduce complications and injury of the important structures and increase the curative effect on the lesions in the sellar region.
