Comparative Study Clinical Trial
Evaluation of minimally invasive percutaneous CT-controlled ventriculostomy in patients with severe head trauma.
Evaluation of percutaneous CT-controlled ventriculostomy (PCV) in patients with severe traumatic brain injury to measure intracranial pressure as a component of early clinical care. A consecutive series of 52 interventions with PCV was prospectively analyzed with regard to technical success, procedural time, time from the initial cranial computed tomography (CCT) until procedure and transfer to the intensive care unit (ICU). Additionally, the data was compared with a retrospective control group of 12 patients with 13 procedures of conventional burr-hole ventriculostomy (OP-ICP). ⋯ The interval from the initial CCT until procedure (PCV 28 +/- 11 min, OP-ICP 78 +/- 33 min) and transfer to the ICU (PCV 69 +/- 34 min, OP-ICP 138 +/- 34 min) could also be significantly reduced (each with p<0.05, Mann-Whitney U-test). Percutaneous CT-controlled ventriculostomy is a safe and efficient method for ICP catheter placement during initial trauma room management. It significantly reduces the time of initial trauma room treatment.

There are many methods described for the treatment of sacrococcygeal pilonidal sinus disease, and none of them has been accepted as an optimal modality. Plastic procedures have some advantages, such as short duration of hospitalization, quick healing time, low risk of wound infection, and lower recurrence rates. Our choice is Limberg flap repair; we present here our experience with this procedure. ⋯ The Limberg flap procedure is an easy and effective technique. Patient comfort, quick healing time, early return to full activity, and low complication and recurrence rates are the important advantages of this procedure.

Case ReportsGlomus tumor of the trachea: value of multidetector computed tomographic virtual bronchoscopy.
Glomus tumor of the trachea is extremely rare. We report a case of tracheal glomus tumor in a 39-year-old man who presented with hemoptysis. The diagnosis was made after bronchoscopic biopsy of a tumor involving the posterior wall of the upper trachea. ⋯ Tracheal sleeve resection with reconstruction was successful, and pathological studies confirmed complete resection and the diagnosis of glomus tumor. The patient was disease-free 3 months postoperatively. To our knowledge, this is the first reported case in which additional computed postprocessing was used to help evaluate the extent of such a tumor.

The goal of this study was to evaluate the accuracy of CT-based computer-assisted pedicle screw insertion in the thoracic spine in patients with fractures, metastases, and spondylodiscitis compared to a conventional technique. A total of 324 pedicle screws were inserted in the thoracic spines of 85 patients: 211 screws were placed using a CT-based optoelectronic navigation system assisted by an image intensifier and 113 screws were placed with a conventional technique. ⋯ Despite use of the navigation system, 1.9% of the computer-assisted screws perforated the pedicle wall by more than 4 mm. The additional use of the image intensifier helped to identify the correct vertebral body and avoided cranial or caudal pedicle wall perforations.
