The data recorded were general parameters (operating time for the whole procedure and for each step), and general and specific parameters of the surgeon’s activities (number of manual gestures, number and duration of actions performed, use of the instruments, and use of interventions on anatomic structures). The Mann-Whitney U
test was used for comparison between the 2 groups of neurosurgeons.
RESULTS: The operating time was statistically lower for the group of senior surgeons. The seniors statistically demonstrated greater click here economy in time and in gestures during the closure step, for sewing and for the use of scissors, needle holders, and forceps. The senior surgeons statistically worked for a shorter time on the skin and used fewer manual gestures on the thoracolumbalis fascia. The number of
changes in microscope position was also statistically lower for this group.
CONCLUSION: There is a relationship between surgical practice, as determined by a method of objective measurement using observation software, and surgical experience: gesture economy evolves with seniority.”
“BACKGROUND: Endosopic MK-8776 clinical trial septum pellucidotomy is used for treating patients with unilateral and specific types of bilateral hydrocephalus. The ideal location for septostomy is controversial; however, an avascular region is preferred.
OBJECTIVE: As the septal veins (SVs) are viewed only from one side, we studied the symmetry of the SVs in
an attempt to define a safe area for septostomy.
METHODS: Sixteen cadaver brains were dissected. The septum pellucidum was exposed bilaterally and divided into 3 regions. SVs of both sides were evaluated according to number, size, distribution, and location relative to common markers on both sides.
RESULTS: Each side included 1 to 7 large veins (mean +/- standard deviation, 2.3 +/- 1.4), 0 to 3 small veins (2.05 +/- 1.73), and a total of 2 to 7 veins (4.35 +/- 1.53). Of the large veins, 88% were located in the anterior septal region (anterior to the foramen of Monro). Among the 10 brains that were extensively dissected, 90% had asymmetric SVs (either in the number of large veins or in the existence of any veins) in at least 1 of the septal regions, and 50% of brains had asymmetric SVs in the anterior science region.
CONCLUSION: Distribution of the SVs is asymmetric in most cases. We recommend septostomy be performed at the anterior area of the middle septal region, at the level of the foramen of Monro, mid-height between the corpus callosum and fornix. Careful evaluation of preoperative images and thorough coagulation at the septostomy site are essential to avoid injury to a contralateral large SV.”
“BACKGROUND: Fusiform anterior communicating artery (ACoA) aneurysms (ACoAAs) are rare, and a series of these aneurysms has not been reported.
