Three dimensional computed tomographic imaging in planning the surgical approach for redo cardiac surgery after coronary revascularization

Three dimensional computed tomographic imaging in planning the surgical approach for redo cardiac surgery after coronary revascularization.

OBJECTIVE Reoperative cardiac surgery after previous coronary artery bypass grafting represents a surgical challenge due to the potential for injury to patent coronary grafts, aorta or right ventricle. Standard preoperative imaging using a coronary angiogram and chest radiograph (CXR) often results in inaccurate assessment of mediastinal anatomy. We aimed to evaluate 3D volume rendered computed...

Computed tomographic imaging in planning redo cardiac surgery after coronary bypass grafting — a roadmap to safety

Patent coronary artery bypass grafts are at risk of injury during redo cardiac surgery. In particular, damage to a patent left internal mammary artery (LIMA) graft during repeat surgery is a well-described and potentially lethal complication [1]. Precise anatomical information is important for planning the surgical approach in reoperative cardiac surgery. The standard preoperative work-up inclu...

Mandibular Dimensional Changes with aging in Three Dimensional Computed Tomographic Study in 21 to 50 Year old Men and Women

Introduction: Raising the knowledge of skeletal and soft tissue changes with aging has been highly essential due to an increasing demand for aesthetic facial surgery following aging. The aim of this study is to evaluate the three dimensional computed tomographic images and process of changes in mandible with aging. Materials and Methods: In this descriptive study, the facial CT scans were obta...

Usefulness of volume-rendered three-dimensional computed tomographic angiography for surgical planning in treating unruptured paraclinoid internal carotid artery aneurysms.

Paraclinoid internal carotid artery aneurysms are difficult to treat and difficult to visualize by using DSA, MRA, or surface-rendered 3D-CTA. Because those aneurysms are surrounded by bone, the dural ring (proximal and distal), the optic nerve, the oculomotor nerve, and the cavernous sinus. This report represents the first attempt to assess the verification of volume-rendered 3D-CTA for surgic...
