INDIANAPOLIS – St.Vincent is participating in a landmark study to evaluate the clinical evidence for safety and efficacy of ultrasound-accelerated thrombolysis (ultrasound energy used with medicine to treat blood clots) in treating patients with life-threatening pulmonary embolism (PE). The study, known as SEATTLE II, is a clinical trial that evaluates the benefits of this advanced treatment technique, which employs a device utilizing ultrasound technology to enhance the speed and efficiency of clot dissolving drugs.
A PE occurs when a large blood clot, usually from a vein in the upper leg, or pelvis, breaks away and lodges in the lungs. The victim's heart may be suddenly overwhelmed with the task of pushing blood past this obstruction. Symptoms are similar to a heart attack.
In this clinical trial, SEATTLE II, a patient is treated by placing a catheter directly into the clotted vein and delivering a clot busting drug into the clot. By doing this, the physician is able to release a lower dosage of the blood clot busting drug, thus decreasing the risk of extensive bleeding.
About 5 percent of PEs are massive; resulting in rapid heart failure and shock. Without immediate therapy death can occur. The traditional method of treating a PE is that a patient receives a large dose of a clot-dissolving drug called a thrombolytic. The drug is delivered into a vein; however, unintended bleeding, often fatal itself, is a much feared side-effect. Up to 40 percent of PE victims have less critical obstructions, often called sub-massive PE, which are currently treated with anti-coagulant medication. These medications do not remove the blood clot; they simply prevent the clot from growing larger. Recently, studies suggest that failure to remove these sub-massive clots may have long-term adverse events including recurrent PE, chronic pulmonary hypertension, and in some cases death. Up to 21 percent of these patients die within 90 days.
The SEATTLE II clinical trial is looking to more efficiently and safely treat PEs that are both massive and sub-massive.
The U.S. Surgeon General reports up to 600,000 patients are stricken with PE in the U.S. resulting in up to 180,000 deaths annually, more than AIDS, breast cancer and auto accidents combined.
