Summary
Selective coil embolization is effective for treating ruptured renal artery aneurysms (RAAs), achieving durable occlusion and preserving renal function. Careful attention to potential contralateral lesions is crucial for treatment decisions.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Renal artery aneurysm (RAA) is a rare vascular condition.
- Treatment options for ruptured RAAs include surgery and endovascular methods, with outcomes and controversies.
- Evaluating endovascular treatment efficacy for ruptured RAAs is essential.
Purpose of the Study:
- To assess the outcomes of ruptured RAAs treated with endovascular techniques.
- To explore the effectiveness of selective embolization in controlling hemorrhage and preserving renal function.
Main Methods:
- A retrospective review of 6 patients with ruptured RAAs from 2001-2011.
- Diagnosis confirmed by Color Doppler ultrasonography (CDU) and CT angiography (CTA).
- Emergency angiography performed, with 5 patients treated by selective coil embolization and 1 by trunk artery occlusion.
Main Results:
- Follow-up averaged 25 months. Selective coil embolization achieved durable occlusion in 4 cases without relapse or significant renal function decline.
- The patient treated with trunk artery occlusion experienced ischemic parenchymal loss and mild kidney atrophy.
Conclusions:
- Superselective coil embolization is a viable option for ruptured RAAs, offering low mortality and good long-term results.
- The potential for bilateral or multiple renal artery aneurysms necessitates careful contralateral evaluation.

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...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

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...
