Asma'a Abdurrahman Al-Ekrish
The article presents an overview of the goal of imaging at each stage of implant therapy and the usefulness and limitations of multidetector computed tomography (MDCT) in achieving those goals. Various MDCT protocols of use in implant imaging also are presented, with an emphasis on dose reduction and the use of iterative reconstruction techniques. Also discussed are options for viewing and analysis of CT images, issues related to appropriate image reformatting and interpretation, interactive treatment planning, and transfer of information from the images to the surgical field during implant surgery using surgical guides and CT-guided navigation systems...

Glioblastoma, a WHO grade IV astrocytoma, is a highly aggressive and heterogeneous tumour that infiltrates deeply into surrounding brain parenchyma, making complete surgical resection impossible. Despite chemo-radiotherapy, the residual cell population within brain parenchyma post-surgery causes inevitable recurrence. Previously, the tumour core has been the focus of research and the basis for targeted therapeutic regimes, which have failed to improve survival in clinical trials. Here, we focus on the invasive margin as defined by the region with 5-aminolevulinic acid (5ALA) (GliolanTM) fluorescence at surgery beyond the T1 enhancing region on magnetic resonance imaging (MRI)...

BACKGROUND: Patients with bitemporal lobe epilepsy are generally not considered for surgical resection. Fortunately, responsive neurostimulation proves another avenue for the management of this challenging disease process. In conjunction with our epileptologist, we consider responsive neurostimulation for patients who have clinical features of temporal lobe epilepsy without clear localization on imaging and stereo-EEG. METHODS: Here we describe our technique for implanting a responsive neurostimulator (NeuroPace, NeuroPace Inc...

Recent advancements in automated diffusion tensor imaging (DTI) and whole brain tractography (WBT) may be of great use to the neurosurgeon in selecting surgical corridors that can minimize disruption of surrounding white matter tracts. This is especially important in cases where the lesion displaces white matter tracts and traditional operative approaches may inadvertently violate these fibers. Here, we present automated DTI seeding and WBT as a practical and efficient means for preoperative surgical planning, in an effort to spare white matter tracts that may be displaced by a variety of lesions and may be vulnerable during surgery...

BACKGROUND: Fluid therapy remains a cornerstone of therapy in shock states. However, fluid overloading ultimately results in edema formation which is related to excess morbidity and mortality. Handheld microscopes are now frequently used to study the sublingual microcirculation. As a corollary, these devices measure focal distance, or surface to capillary distance. Physiologically, this could represent a microvascular index of edema formation and could have the potential to guide fluid therapy...

REVIEW
Brian Whang
Thoracic surgeons are sometimes asked to consult on the management of a patient who is pregnant. Conditions commonly encountered are empyema, spontaneous pneumothorax, and diaphragmatic hernia. Lung cancer is rarely seen in pregnancy, but its incidence is rising. Diagnostic imaging and perioperative management involve the navigation of fetal risks and nuances in maternal physiology. Shared decision making within a multidisciplinary framework will optimally guide the course of management.

RATIONALE: Merkel cell carcinoma (MCC) is an aggressive neuroendocrine-derived cutaneous cancer. Ectopic or single metastatic MCC located in thorax is extremely rare; meanwhile, its definite management has not been elucidated yet. PATIENT CONCERNS: A 64-year-old female patient with a giant mass located in her left thorax was presented for stuffy pain of left chest for 6 months and fever for half a month. She underwent radical resection of vulvar MCC 10 years ago...

In high-grade glioma surgery, tumor resection is often guided by intraoperative fluorescence imaging. 5-aminolevulinic acid-induced protoporphyrin IX (PpIX) provides fluorescent contrast between normal brain tissue and glioma tissue, thus achieving improved tumor delineation and prolonged patient survival compared with conventional white-light-guided resection. However, commercially available fluorescence imaging systems rely solely on visual assessment of fluorescence patterns by the surgeon, which makes the resection more subjective than necessary...

BACKGROUND: Several methods including free-hand technique, fluoroscopic guidance, image-guided navigation, computer-assisted surgery system, robotic platform and patient's specific templates are being used for pedicle screw placement. These methods have screw misplacements and are not always easy to be applied. Furthermore, it is necessary to expose completely a large portions of the spine in order to access fit entirely around the vertebrae. METHODS: In this study, a multi-level patient's specific template with medium invasiveness was proposed for pedicle screw placement in the scoliosis surgery...

Reinfection after two-stage revision hip arthroplasty (RHA) is still a complex issue. Only few studies revealed the factors affecting the success rate in the treatment of periprosthetic hip infection (PHI), especially risk factors. A retrospective study was conducted using records of 30 patients underwent two-stage RHA for infected total hip arthroplasty (THA). Treatment was defined as successful if a patient did not need any reoperation or invasive procedure such as image-guided drainage during the two years after reimplantation...

BACKGROUND: Our aim was to evaluate the ease and utility of using indocyanine green fluorescence angiography for intraoperative localization of the parathyroid glands. METHODS: Indocyanine green fluorescence angiography was performed during 60 parathyroidectomies for primary hyperparathyroidism during a 22-month period. Indocyanine green was administered intravenously to guide operative navigation using a commercially available fluorescence imaging system. Video files were graded by 3 independent surgeons for strength of enhancement using an adapted numeric scoring system...

Of the many imaging technologies, some have the potential to be used in image-guided surgery and therapy (IGS/IGT). This review of relevant papers on IGS/IGT for lung cancer indicates effective localization and IGS/IGT in early endobronchial lesions by fluorescence bronchoscopic technique. Visualization of early peripheral (nodular) tumors at operation can be achieved by a variety of imaging methods and devices which allow identification, localization and provision of intraoperative real-time images. Recent developments employing fluorescence contrasts and near infra-red light have shown encouraging feasibility and outcome in providing reliable methods for the IGS of cancer generally and lung cancer more specifically with provision of real time intraoperative imaging...

OBJECTIVE: Several radiological studies have suggested that the base of the Appendix often does not correspond with Mc Burney's point. The aim of our study is to assess the value of using CT localization of the appendicocaecal junction to guide placement of the appendicectomy incision. DESIGN & METHOD: 32 consecutive patients, booked for open appendicectomy were prospectively included in this study. Coronal and axial CT scans with IV contrast were studied to assess site of the appendicocaecal junction...
