Summary
Ultrasound-enhanced thrombolysis effectively treats arterial and venous clots, achieving high success rates in acute and chronic cases. This method offers a faster lysis time compared to conventional treatments.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Cardiovascular Medicine
Background:
- Thrombosis, encompassing both arterial and venous occlusions, presents a significant clinical challenge.
- Conventional thrombolysis can be time-consuming and may have limitations in achieving complete clot lysis.
Purpose of the Study:
- To evaluate the clinical efficacy and outcomes of ultrasound-enhanced thrombolytic therapy.
- To assess the treatment of both acute and chronic arterial and venous thromboses using this technique.
Main Methods:
- A single-center study involving 33 patients with 36 occlusions treated between January 2005 and June 2006.
- Ultrasound-enhanced thrombolytic therapy utilized urokinase infusion via an infusion catheter after diagnostic angiography.
- Dosage ranged from 80,000-120,000 IU/h for urokinase infusion.
Main Results:
- High technical success rates were observed: 96% for arterial occlusions and 83% for venous occlusions.
- Complete lysis was achieved in the majority of cases, with average lysis times of 16.4 hours for arterial and 21.2 hours for deep vein thrombosis.
- Two cases of chronic occlusions (superficial femoral artery and iliac vein) were refractory to therapy.
Conclusions:
- Ultrasound-enhanced thrombolysis is a successful treatment modality for both acute and chronic arterial and venous thromboses.
- This technique demonstrates a high success rate and potentially shorter treatment times compared to conventional thrombolysis.

Venous Thrombosis III: Interprofessional Care
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
Anticoagulant Drugs: Low-Molecular-Weight Heparins
Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
