Summary
Percutaneous thrombin injection shows promise for treating visceral arterial pseudoaneurysms (PAs). This minimally invasive technique achieved technical success in 10/19 patients, particularly for smaller distal PAs, with no complications.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Gastroenterology
Background:
- Visceral arterial pseudoaneurysms (PAs) are rare but serious vascular abnormalities.
- Causes include pancreatitis, iatrogenic injury, infection, and trauma.
- Treatment options for PAs have evolved, with a need for minimally invasive approaches.
Purpose of the Study:
- To evaluate the efficacy and outcomes of percutaneous thrombin injection for visceral arterial pseudoaneurysms (PAs).
- To assess the safety and technical success of this novel treatment modality.
Main Methods:
- Retrospective review of 19 patients with visceral PAs treated between 2014-2019.
- Percutaneous ultrasound-guided thrombin injection was the primary intervention.
- Technical success was defined by the absence of PA flow on follow-up ultrasonography.
Main Results:
- Overall technical success rate was 10/19 patients.
- Higher success rates were observed in distal branch PAs (9/13) compared to main vessel PAs (1/6).
- Smaller pseudoaneurysms (<23mm) had better outcomes (7/12) than larger ones (3/7); no complications were reported.
Conclusions:
- Ultrasound-guided percutaneous thrombin injection offers a painless, cost-effective, and radiation-free treatment for visceral pseudoaneurysms.
- This technique demonstrates potential as a novel therapeutic option.
- Further large-scale studies are warranted to confirm its 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...

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

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...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.0K
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

1.1K
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...

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...
