Summary
Embolization is a key treatment for severe lower gastrointestinal bleeding (LGIB). Modern imaging and embolization techniques, including detachable coils and liquid agents, enhance speed and effectiveness in emergency settings.
Area of Science:
- Interventional Radiology
- Vascular Surgery
- Gastroenterology
Background:
- Lower gastrointestinal bleeding (LGIB) presents significant morbidity and mortality risks.
- Embolization is a primary treatment for acute, life-threatening LGIB when endoscopy fails or is not feasible.
- Timeliness is critical in emergency procedures, impacting patient outcomes.
Purpose of the Study:
- To review modern tools and techniques for embolization in acute lower gastrointestinal bleeding.
- To highlight advancements improving the speed and efficacy of interventional procedures for LGIB.
Main Methods:
- Utilizing non-selective cone-beam CT arteriography for rapid vessel identification.
- Employing advanced software for direct microcatheter placement into bleeding vessels.
- Evaluating the efficacy of detachable coils and liquid embolic agents.
Main Results:
- Modern imaging and software enable faster identification and access to bleeding sites compared to traditional angiography.
- Specific embolic agents like detachable coils and liquid embolics demonstrate superior advantages.
- These advancements contribute to safer and more effective embolization procedures.
Conclusions:
- Advanced imaging and embolization techniques are transforming the management of acute LGIB.
- The integration of cone-beam CT and sophisticated software improves procedural efficiency.
- Detachable coils and liquid embolics represent effective choices for treating acute LGIB, enhancing patient safety and outcomes.

01:28Esophageal Varices-II: Clinical Features and Management
752
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.

651
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...

654
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

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...
