Abstract

The authors describe a new technique using the principle of rotational scanography, in which the x-ray tube is rotated through the center of the focal spot and scans the field of interest. A single primary and secondary slot system in conjunction with an 8:1 grid is used for efficient scatter removal. If the speed of blood flow is increased by reactive hyperemia and a large amount of contrast medium is injected, the abdomen to the toes can be scanned with one injection. The advantages of this technique are that a 127-cm field can be covered with a 6 degree or 12 degree target tube and without an especially high ceiling, and the film changer is eliminated. The angiograms are markedly improved because virtually all scatter is eliminated, and exposure is reduced since only one radiograph is necessary.

Transhepatic vascular access for diagnostic and interventional procedures: techniques, outcome, and complications.

Early or multiple cardiac catheterizations may result in occlusion of the femoral veins prohibiting their use. The internal jugular or sub-clavian approach may be an appropriate alternative. However, these approaches may not be suitable in patients with surgical interruption of the superior vena cava. In other patients, they may not allow easy access to certain areas of the heart. The transhepatic approach is an important alternative route for performing cardiac catheterization and interventions. Depending on the planned procedure, it may be the preferred route to perform the cardiac catheterization even in the presence of patent femoral veins. The indications, technical details and potential complications of this approach are discussed.

Embolization for a bleeding pelvic fracture in a patient with persistent sciatic artery.

Emergency embolization for a bleeding pelvic fracture was performed in a patient with persistent sciatic artery, a rare anatomic variation in which the internal iliac artery continues to the popliteal artery. Successful hemostasis was achieved without complications by means of selective catheterization into each branch of the internal iliac artery. Awareness of this unusual vascular anatomy is critically important to avoid serious complication of emergency embolization.
