Australasian Journal of Ultrasound in Medicine November 2010 13 (4) Introduction The purpose of this paper is to provide a focused overview of the key concepts in the assessment of lower limb chronic venous insufficiency (CVI) with an emphasis on specific techniques which can assist the sonographer or sonologist in achieving an accurate and time-efficient examination. In the context of this pap...

The steady decline with time in patency of expanded polytetrafluoroethylene (e-PTFE) dialysis shunts led to a trial protocol of postimplantation surveillance to identify those grafts at risk for thrombosis. Duplex scanning is a noninvasive, reproducible method of monitoring anatomic and hemodynamic aspects of graft function that provides the surgeon with an opportunity for early operative inter...

Temporal artery is superficially exhibited and easily traumatized. Rarely, a minor and blunt trauma, especially in elderly who are under anticoagulants, can cause a pseudoaneurysm. Diagnosis should be based, primarily, on history and physical examination and secondarily on duplex ultrasound scanning which will lead to confirmation and preoperative planning. The therapeutical plan consists of su...

Recent developments in vascular surgery have occurred in many areas. The topics of intimal hyperplasia and reperfusion injury are the subject of much current research and possible methods of treatment are at an early stage of development. Advances in perioperative care have contributed to a reduction in mortality and morbidity. Endovascular techniques are being employed widely but the indicatio...

Noninvasive imaging of the aorta has undergone consid­ erable refinement in recent years. This has been brought about by significant technologic advances in computed tomography (CT), magnetic resonance (MR) techniques, and duplex ultrasound (US) scanning. Three-dimensional techniques and shorter acquisition times for CT and MR imaging have made it possible to time the infusion of contrast mediu...
