20 years of MIS

Scientific studies confirm that after 20 years of minimally invasive surgery (MIS) most of these operations have advantages over the equivalent, conventional surgical procedures.

German Radiology Congress 2008

Along with paediatric radiology, interventional radiology will have a high profile at the 89th German Radiology Congress and 5th Joint Congress with the Austrian Radiology Society. Congress presidents Professor Dierk Vorwerk and Professor Richard Fotter outlined what's on the agenda for the expected 6,900 visitors. Training, they pointed out, will aim at those preparing to specialise in…

Varicose veins

USA - A next-generation radiofrequency ablation catheter - the VNUS ClosureFASTTM - has been used by surgeon Phillip Levin MD, at Cedars-Sinai, in Los Angeles, California. An expert in VNUS closure procedure, Dr Levin has treated approximately 300 patients since 2003 with the ClosureFASTTM catheter's predecessor.

Determining vascular age

New to the Siemens Medical Solutions portfolio of ultrasound applications is the syngo Arterial Health Package (AHP), which calculates cardiovascular risks by measuring carotid intima media thickness and determining the relative `vascular age´ of the vessel. Using this, along with, for example, cholesterol values and blood pressure, a physician can better assess a patient's myocardial or…

Advanced Dynamic Flow (ADF)

Ultrasound scanning with CCDS is an established technique in shunt diagnostics and allows non-invasive assessment of vascular flow. Stenosing changes to walls of vessels used as a dialysis shunt should be detected as early as possible to avoid occlusion by a thrombus. High occlusion rates with volume flow reduced by up to 45% in one year demand ultrasound screening. The risk of haemodynamically…

Monitoring of Surgical Bypasses

The aortocoronary bypass is an important surgical method for multivessel coronary revascularization, especially in the presence of complex lesions and in diabetic patients. It is can improve the prognosis of patients with three vessel disease and with left ventricular dysfunction1 . With regard to the type of graft used, bypasses are split into venous and arterial types. The use of venous…

Carotid Plaque Imaging

Ischaemic stroke accounts for 80-85% of all cerebrovascular accidents and causes considerable morbidity and mortality, thereby placing a significant burden on western societies. In the UK alone, stroke costs amount to 10.4 billion EUR annually. These events commonly are a consequence of systemic atherosclerotic disease and with the internal carotid arteries supplying 75% of cerebral blood flow,…

Aplio - Dynamic and Advanced Dynamic Flow

There are a number of problems in contrast imaging using LevovistTM contrast agent. In Doppler mode, the problems are poor resolution and large areas of blooming. In 2nd harmonic imaging and pulse inversion imaging, there are problems related to tissue harmonic imaging (THI) because Levovist requires a high mechanical index (MI). THI increases under high-MI conditions, and THI interferes with…
