Abstract
The placement and use of airway and vascular emergency accesses devices are life-saving procedures for mechanical support of ventilation and maintaining patent air way as well as maintaining a constant and stable central vascular line; failures to secure the airways drastically increases morbidity and mortality of patients within a very short time.
During the last decade, the spread of computed tomography and the improvement of image post-processing software enabled visualization of the airways in the form of three-dimensional reconstructed models.
Multidetector computed tomography has the advantage of safety and speed in evaluation of immediate complications related to time of placement of vascular access devices in the neck as well as delayed complications developing later during the prolonged insertion of the device.
The goal of the study is to assess the role of multidetector computed tomography (MDCT) in evaluation of complications of upper airway and neck vascular access devices.
This study was conducted on 25 patients with complications involving the airway and vascular access devices in the neck and upper chest regions using MDCT for diagnosis and assessment.
All patients were subjected to the following:
o Thorough history taking.
o Multi-detector computed tomography imaging.
Reconstruction methods:
• The soft tissue and bone windows of the CT images were done.
• The access devices were thoroughly assessed.
• Axial volumetric acquisition was taken and completed with reformations of coronal and sagittal images.
• Image reconstruction and manipulation were interpreted by dedicated workstation (Osirix ROI SR workstation).
• The most common complication encountered was abnormal location of the 8/25 representing 32% of all complications and in patients with airway devices complications (from groups B & C) it was reported in 4 cases (3/8 in group C patients and only 1 case in group B) and equally tracheal stenosis also was reported in 4/25 cases representing 16% of all complications (3/4 in group B patients and only 1 case in group C). Infection related to the inserted device was reported in 3/25 cases representing 12%, 2 of them were in group B patients and only 1 in group C patients; with the same number of patients 3/25 low lying device
