In off-line IFI analysis, the graft washout was classified based on the number of heart beats required for ICG washout: Diagnostic evaluation of patients with chest pain or other signs and symptoms highly suggestive of ischemic heart disease and who have uninterpretable or equivocal ECG changes caused by drugs, bundle branch block or left ventricular hypertrophy.

Assessment of vascular patency after clipping was also investigated. The number of ICGA-detected occult choroidal recurrences amounted to Outcomes of interest including anastomotic leak rate, change of operative strategy and time taken for FA were recorded.

Indocyanine Green Angiography

Dashti et al evaluated the reliability of ICGA in the evaluation of neck residuals and patency of branches after micro-neurosurgical clipping of intra-cranial aneurysms IAs. You will likely need to stop eating and drinking hours before the procedure.

After aneurysms being clipped, intra-operative ICGA found remnant of aneurysms, stenosis or occlusion of parent arteries and grafts in 8 cases, which were revised in the same surgical procedure.

Prospective analysis has shown 28—32 F to effectively drain hemothorax without resulting in increased retained hemothorax. These researchers evaluated multiple, quantitative parameters to assess perfusion.

In diagnostic Nuclear Medicine, the subject first incorporates tracer amounts of a radioactively-labelled molecule.

ATLS 10th edition offers new insights into managing trauma patients

The simplicity of the method and the speed with which the investigation can be performed indicate that this technique may help to improve the quality and outcome of surgical procedures and reduce the need for intra- or post-operative angiography in selected cases.

The attenuation characteristics of a saccular aneurysm vary, depending on whether the lesion is patent and partially or completely thrombosed. Airway and Ventilation The rapid assessment of the airway by determining the ability of the patient to speak and answer questions appropriately, in addition to verifying adequate ventilation and circulation, has long been a key element in the treatment of trauma patients.

Massive transfusion is defined as the transfusion of more than 10 units of blood in 24 hours or more than four units in one hour. Additional data on functional monitoring, temporary venous clipping, and flow measurements were also recorded.

In this group one in every CT scans was followed by an excess cancer. Methods A retrospective review of patients treated for acute spontaneous or posttraumatic carotid artery dissection over a year period from August to July was performed. The authors concluded that ICGA is a simple, reliable and cost-effective method.

Aneurysm clipping was applied in patients. Radical resection was achieved in 4 cases. The majority 49 eyes, An operating microscope-integrated light source containing infrared excitation light illuminated the operating field and was used to visualize an intravenous bolus of ICG.

Neurosurgery for Cerebral Aneurysm

The post-operative angiographic results were consistent with findings on intra-operative ICG angiograms in patients When a 1 g dose is given in the prehospital setting, a repeat dose is administered in the emergency department.

However, they stated that more studies with higher level of evidence are currently lacking to validate this technology. The authors stated that an emerging technology using near-infrared angiography with ICG dye may significantly improve the immediacy and accuracy of the assessment of flap perfusion.

Aetna considers the Spy Elite System near-infrared angiography with indocyanine green experimental and investigational for breast reconstruction surgery, evaluation of anastomotic perfusion in colorectal surgery and mapping of sentinel lymph node in cutaneous melanoma, and all other indications because the safety and effectiveness of this approach has not been established.

Coverage is limited to devices that process thin, high resolution slices 1mm or less.

Cardiac CT, Coronary CT Angiography, Calcium Scoring and CT Fractional Flow Reserve

Recently, ICG and near-infrared imaging have been used to aid in sentinel node biopsy. There were no adverse effects after injection of ICG. Post-operative computed tomography and computed tomography angiography CTA were performed for all patients.

Moreover, using fundus images DME can be identified and automated. Its uses include diagnosis and staging of cancer, as well as follow up after cancer treatment to assess response. Between May and Octoberall anastomosis and resection margins in colorectal surgery were investigated using FA intra-operatively to evaluate colonic perfusion before and after completion of the anastomosis, both in right and left colectomies.Chapter-by-chapter content updates in the ATLS 10th edition are summarized, including key revisions to shock, thoracic, head trauma care, and other topic areas.
