Summary
A new funneled sheath offers embolic protection during mechanical thrombectomy for deep venous thrombosis, reducing risks. While effective, proper technique is crucial for optimal outcomes in clot removal procedures.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Medical Device Technology
Background:
- Mechanical thrombectomy is a key treatment for deep venous thrombosis (DVT).
- A significant risk during DVT mechanical clot removal is intraprocedural pulmonary embolism (PE).
- Embolic protection devices aim to mitigate these risks.
Purpose of the Study:
- To evaluate the effectiveness of a novel funneled sheath for embolic protection during mechanical thrombectomy.
- To assess the safety and utility of this device in DVT treatment.
Main Methods:
- Retrospective review of 55 procedures utilizing the funneled sheath device.
- Analysis of device deployment success, clot capture, and embolic complication rates.
Main Results:
- Successful device deployment in all 55 cases.
- Clot retrieval within the funnel observed in 24% of procedures.
- Two instances of intraprocedural PE and one air embolism were recorded.
Conclusions:
- The funneled sheath provides effective embolic protection during mechanical thrombectomy for DVT.
- Careful procedural technique is essential when using this device to maximize safety and efficacy.

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...

01:30Venous Thrombosis I: Introduction
294
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration.

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

1.2K
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

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...
