Abstract

The many available methods of digital subtraction angiography (DSA) are briefly reviewed. At present the most commonly used are temporal filtration techniques, which include conventional subtraction, integrated remasking , and various types of filtering. Their present use in intravenous, as well as intra-arterial, DSA is shown. The "moving mask" subtraction technique for cardiac and coronary studies is of particular interest. The current status of second-order subtraction techniques such as tomographic DSA and parametric digital imaging is presented. The latter method is particularly useful for demonstration of shunts. Finally, several examples of non-angiographic and future applications of digital radiography are presented.

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.
