Therapeutic embolisation is indicated in all except
**Core Concept**
Therapeutic embolization is a minimally invasive procedure that involves blocking the flow of blood to a specific area of the body, usually to treat a medical condition such as bleeding, tumors, or vascular malformations. This procedure is typically performed using various embolic agents, including coils, particles, and liquids, which are delivered through a catheter to the target site.
**Why the Correct Answer is Right**
The correct answer is based on a thorough understanding of the indications and contraindications of therapeutic embolization. This procedure is often used to control bleeding, treat vascular malformations, and manage certain types of tumors. However, the use of therapeutic embolization in certain conditions, such as acute ischemic stroke, is generally contraindicated due to the risk of worsening neurological deficits.
**Why Each Wrong Option is Incorrect**
**Option A:** Arteriovenous malformations (AVMs) are a common indication for therapeutic embolization, as it can help reduce the risk of bleeding and alleviate symptoms.
**Option B:** Tumors, particularly those that are highly vascular, are often treated with therapeutic embolization to reduce blood flow and alleviate symptoms.
**Option C:** Cerebral aneurysms are another indication for therapeutic embolization, as it can help prevent rupture and subsequent bleeding.
**Clinical Pearl / High-Yield Fact**
It's essential to note that therapeutic embolization should only be performed by experienced interventional radiologists or neurointerventionalists, as the procedure carries risks and complications, including stroke, brain damage, and death.
**Correct Answer:** D. Acute ischemic stroke
