Percutaneous Mechanical Thrombolysis
Investigative Radiology, 1991Schmitz-Rode T, Gunther RW. Percutaneous mechanical thrombolysis: a comparative study of various rotational catheter systems. Invest Radiol 1991;26:557-563. In vitro fragmentation of thrombi was performed with the Kensey catheter, the Bildsoe catheter, the Gunther aspiration catheter, and two modified aspiration catheters in a model circuit under ...

Mechanisms of ultrasonic thrombolysis
2009 38th Annual Symposium of the Ultrasonic Industry Association (UIA), 2009An ultrasonic transversely vibrating wire delivers energy to an active zone to facilitate thrombolysis in a blood vessel. Ultimately, all the energy delivered into the treatment region at the active zone ends up as heat. The heat created can originate from three sources.

Mechanical thrombolysis of acute ischemic stroke
Journal of Stroke and Cerebrovascular Diseases, 2001Chemical thrombolysis has been the mainstay of acute stroke treatment; however, these methods come with the risk of potentially lethal intracerebral hemorrhage. This article discusses the different methods of mechanical thrombolysis and other techniques used in the treatment of acute stroke, including angioplasty and stent placement.

Journal of Thrombosis and Haemostasis, 2004
The delivery of encapsulated plasminogen activators has demonstrated enhanced thrombolysis in vivo in several models. The mechanism of such improvement has not previously been established.We explored in vitro the mechanism by which microencapsulation of streptokinase in polymeric microparticles accelerates clot digestion and reduces reperfusion times ...

The pharmacological use of plasminogen activators is associated with symptomatic improvement in patients with coronary artery thrombosis, peripheral arterial occlusions, and thrombosis of the venous system. Based on prospective angiographic studies and planned programs (1, 2, 3, 4, 5), thrombolysis is the only approved treatment of acute ischemic ...

[Percutaneous thrombectomy and mechanical thrombolysis].
RoFo : Fortschritte auf dem Gebiete der Rontgenstrahlen und der Nuklearmedizin, 1998Treatment of acute embolic and thrombotic occlusions of arteries has to be initiated immediately to save the limb at risk. Surgery has been the treatment of choice for the last decades. Percutaneous mechanical methods for thrombectomy and thrombolysis have evolved and offer alternative treatment options, reducing the peri-operative risk.

Mechanical Thrombolysis of Thrombosed Central Venous Port
CardioVascular and Interventional Radiology, 2014To evaluate the effectiveness of a mechanical thrombolysis for thrombosed central venous port (CVP).A total of 38 patients (22 women and 16 men, median age of 55 years) were referred to our interventional unit for thrombosed implanted CVPs. The period between CVP implantation and the initial suspicion of mechanical complication varied from 2 to 35 ...

Some Aspects of the Mechanism of Thrombolysis
Thrombosis and Haemostasis, 1961Summary1. Antibody to streptokinase and kinase, activator and plasmin inhibitors in the circulating blood of man, inhibit parenterally injected streptokinase and streptokinase-plasmin, in vivo. In vitro assays of these inhibitors determine the priming dose of streptokinase and streptokinase-plasmin to neutralize the inhibitors and effect thrombolysis.2.

Thrombolysis and mechanical thrombectomy for arterial disease
Surgical Clinics of North America, 2004Thrombolytic therapy has been around for close to 30 years now,but its exact role in the treatment of acute and chronic arterial occlusive disease continues to be debated. Studies have produced varying and contradictory results. We are still not sure if thrombolysis has any true advantages over surgical thromboembolectomy,or which lytic agent is the ...

Successful thrombolysis on a mechanical tricuspid prosthesis
European Heart Journal, 1989Recombinant tissue-type plasminogen activator (rt-PA) is presently used for the treatment of different clinical entities, mostly myocardial infarction. Its use for treatment of thrombotic dysfunction of prosthetic cardiac valves is more recent and has been only rarely reported.
