| Popis | earning objectives To demonstrate the importance of appropriate imaging before endovascular treatment of deep vein thrombosis (DVT), to discuss advantages and disadvantages of different imaging modalities and to show pathological conditions associated with DVT. Background Endovascular treatment of DVT represented by local pharmacological and mechanical thrombolysis plays an important role in the management of this unrare disease. Besides the clinical parameters, the choice of appropriate treatment is influenced by diagnostic imaging. The main goal of the pre-procedure imaging is to reveal possible underlying morphological changes and to determine the proximal extend of the thrombosis. Clinical Findings/Procedure The most common and, in some cases, the only imaging modality in pre-procedure planning is ultrasound. Besides its physical limitations, it is a highly examiner-dependent modality. Computed tomography is the most common and precise method nowadays, but it is accompanied with significant radiation load. Magnetic resonance imaging also can provide sufficient data, but because of its limited availability and higher time and technical demands, it is still used rarely, although a high number of treated patients are young (mainly women). Multiple cases associated with DVT (retroperitoneal, pelvic and groin tumours, vena cava abnormalities, compression syndrome, vena cava thrombus etc.) are presented to bring an overview of possible pathological changes and characteristic findings. Conclusion Appropriate imaging is a mandatory part of pre-procedure planning in endovascular treatment of DVT. |
