Percutaneous Treatment of Failed Native Dialysis Fistulas: Use of Pulse-Spray Pharmacomechanical Thrombolysis as the Primary Mode of Therapy

OBJECTIVE To determine the efficacy and outcome of percutaneous treatment in restoring the function of failed native arteriovenous fistulas (AVFs) where pulse-spray pharmacomechanical thrombolysis was used as the primary mode of therapy. MATERIALS AND METHODS From June 2001 to July 2005, 14 patients who had thrombosis of native AVFs underwent percutaneous restoration following 20 episodes of ...

Local Thrombolysis for Acute Massive Pulmonary Embolism using a Pulse-Infusion-Thrombolysis Catheter

Acute massive pulmonary embolism (PE) is a common life-threatening condition requiring emergent and suitable treatment. The aim of this study is to assess the efficacy and safety of local thrombolysis with a pulse-infusion-thrombolysis (PIT) catheter in the management of acute massive PE. Thirty-nine patients with PE were treated with catheter directed intervention (CDI). CDI involves suction e...

Laser thrombolysis using long pulse frequency-doubled Nd:YAG lasers.

BACKGROUND AND OBJECTIVE Laser thrombolysis is a means for clearing blood clots in occluded arteries. Many researchers have studied the mechanisms of clot ablation, and research clinicians have used the technique to treat myocardial infarction with a number of different laser systems. Specifically, a 1-microsec pulsed dye laser has been used clinically to remove blood clots in coronary arteries...

Effect of pulse repetition frequency of high-intensity focused ultrasound on in vitro thrombolysis.

Vascular occlusion by the thrombi is the main reason for ischemic stroke and deep vein thrombosis. High-intensity focused ultrasound (HIFU) and histotripsy or microtripsy pulses can effectively dissolve the blood clot with no use of thrombolytic agent and ultrasound contrast agent (microbubbles). In this study, HIFU bursts at the same duty cycle (2%) but varied pulse repetition frequency (PRF) ...
