Transcatheter embolisation of arterial aneurysms
The British Journal of Radiology
|April 1, 1986
Summary
Transcatheter embolisation effectively treats bleeding aneurysms and pseudoaneurysms. Occluding feeding vessels, rather than the aneurysm itself, is a safe and efficient technique.
Area of Science:
- Interventional Radiology
- Vascular Surgery
Background:
- Bleeding aneurysms and pseudoaneurysms pose significant clinical challenges.
- Transcatheter embolisation offers a minimally invasive treatment option.
Observation:
- Eleven cases of bleeding aneurysms/pseudoaneurysms were treated.
- Treatments involved various vascular territories, with and without arteriovenous fistulas.
- Gelfoam and steel coils were used as embolic agents.
Findings:
- Steel coil embolisation demonstrated high efficiency.
- Occluding the feeding proximal vessel, not the aneurysm cavity, was successful.
- This approach reduces the risk of aneurysm rupture and promotes clotting.
Implications:
- Transcatheter embolisation is a viable treatment for complex vascular lesions.
- Proximal vessel occlusion is a preferred, safer embolisation strategy.
- This technique preserves the aneurysm wall and facilitates thrombosis.

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...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

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...
