These results in a small number of patients warrant further investigation to evaluate the role of percutaneous stents in femoropopliteal aneurysms. Until further data of clinical studies are available, this method cannot be recommended, and it cannot replace surgical treatment.
Activity of rt-PA-induced fibrinolysis rises distinctly with higher temperatures. Since even healthy subjects show a physiologic decline in body temperature in the extremities, in patients with occlusive arterial disease decreased activity of fibrinolysis with rt-PA can be expected. Controlled hyperthermia may improve fibrinolysis with rt-PA and should be investigated in vivo.
Venous stent placement is widely accepted as the treatment of stenoses caused by external tumour compression to reduced clinical sequelae. We report percutaneous stent placement into a severely obstructed right pulmonary artery in a 73-year-old female patient. The underlying disease was a medistinal tumour mass of unknown aetiology. Pulmonary perfusion was successfully but temporarily restored by the intervention.
The devices showed performance differences. The SET catheter alone and with a guide wire and the HL may bear an increased risk of procedure-related anemia. In clinical applications, hydrodynamic thrombectomy might substantially reduce the need for thrombolytic therapy.
The combination of 2D-PC-MRA with triggered 2D-TOF-MRA detects stenotic lesions in the lower extremity arterial system with high sensitivity and specificity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
