X-PASTE scoring system

Patients after treatment for saphenous reflux, by whatever method, can develop a thrombus at the site of treatment. This may extend proximally into the common femoral vein or popliteal vein. In rare cases, it may occlude the deep vein like a DVT. Whilst the early stages of the process are usually symptomless, terminating and resolving… Read More »

Scarring post DVT

A deep vein thrombosis (DVT) in the leg may cause several pathological lesions. These include obstruction, stenosis and scarring of the vein wall. Whilst imaging methods may detect the main lesions, it is likely that the DVT process affects all the leg veins, resulting in a more stiff system which is less capable of facilitating… Read More »

Plethysmography

A plethysmograph is a device used to measure an alteration in volume in response to a manoeuvre or change in circumstance. It is unable to measure absolute volume or determine the reason for the volume change. Regarding the leg, it can measure the rate of volume reduction in response to leg elevation as well as… Read More »

Iliac stenosis on duplex

The non-invasive evaluation of an iliac vein stenosis remains a significant challenge. Furthermore, it is unclear which geometric configuration is the most important in causing resistance to flow. The minimum diameter has been proposed as a better index of resistance in contrast to a cross-sectional area reduction. This can be likened to a garden hose… Read More »

Free-floating thrombus

The term free-floating thrombus (FFT) is not exact because they are attached to the vein wall by a base and not actually “free”. A true free thrombus is termed an embolism. A FFT within the veins of the leg represents a potentially serious situation. Detachment can cause travel into the deep veins and then into… Read More »

Pharmaco-mechanical thrombolysis

Traditionally the management of a deep vein thrombosis (DVT) was easy and straight forward. Patients diagnosed would receive a short course of intravenous heparin followed by oral warfarin. The warfarin would be continued for 6 months. Compression stockings were advised and prescribed in most circumstances. Within the last 10 years the management of DVT has… Read More »
