Methods and Materials
We retrospectively reviewed all the neurosurgical procedures performed at our center from January 2011 to April 2012,
following-up our patients until December 2012.
From an overall of 610 neurosurgical cranial procedures we included 411,
only those in wich the technique was burr holes,
craniectomy,
craniotomy or cranioplasty,
and excluding all the ventricular shunt placement procedures.
Postoperative control was carried out with CT,
MRI and cerebral angiography,
evaluating both expected imaging findings and complications.
With this 411 procedures we created a database in wich we included the personal data,
surgery indication (tumor,
vascular disease,
trauma or others),
date and type or surgery (urgent or programmed),
appearance of complications,
and type and date of complications if any.
The complications were classified as tension neumocephalus,
infection (sof tissue infection,
bone flap infection,
empyemas or brain abscesses),
hemorrhages (intraparenchymal,
intraventricular,
and subdural or epidural hematomas),
hydrocephalus,
infarction and others,
and we calculated the frequency of each one.
We also calculated the rate of complications in all of the 411 neurosurgical procedures,
according to the surgery indication and the type of surgery.
We finally used the chi-square test (“χ² test”) to prove if the differences between the different samples were stadistically significant from the average.
