In the treatment of Type II endoleaks, what is the purpose of the translumbar approach?

The translumbar approach in the treatment of Type II endoleaks is primarily utilized for injecting contrast and placing coils. Type II endoleaks are characterized by blood flow into the aneurysm sac from collateral vessels, such as the lumbar arteries or inferior mesenteric artery. When addressing these leaks, an interventional radiologist can access the involved blood vessels through the lumbar region.

By employing the translumbar approach, the clinician aims to accurately visualize the endoleak via fluoroscopy or other imaging modalities by injecting contrast material. This step is crucial, as it helps confirm the diagnosis and the location of the endoleak. Once the endoleak's source is identified, coils can then be deployed to occlude the problematic vessels and effectively mitigate blood flow into the aneurysm sac. This endovascular technique is less invasive and can reduce the complications associated with surgical interventions, making it an effective treatment strategy for Type II endoleaks.

The other choices suggest methods that do not align with the direct management strategies employed for Type II endoleaks. Monitoring renal blood flow and performing an open repair do not address the specific issues associated with this type of endoleak. Similarly, installing a stent graft is more relevant for other types of end
