Digital Subtraction Angiography How Many Days Of Hospitalization Are Required

Digital subtraction angiography (DSA) is a widely used diagnostic procedure for evaluating cerebral vascular conditions. For patients undergoing DSA alone, the typical hospital stay ranges from 3 to 5 days. However, if additional interventional procedures are performed during the angiography, the length of hospitalization may be extended depending on the complexity of the case and the patient's overall health condition.

What Is Digital Subtraction Angiography

Also known as digital subtraction angiography (DSA), this procedure involves injecting an iodine-based contrast agent into the targeted cerebral blood vessels. This allows physicians to obtain highly detailed images of the vascular structure. DSA is considered the gold standard for diagnosing various cerebrovascular conditions such as arterial stenosis, occlusion, arteriovenous malformations, aneurysms, and arteriovenous fistulas.

Why Hospitalization Is Required

Although DSA provides highly accurate diagnostic information, it is an invasive procedure that requires close monitoring. For this reason, patients must be hospitalized to ensure safety and proper post-procedure care. In cases where no intervention is performed and the procedure is purely diagnostic, patients typically remain in the hospital for 3 to 5 days.

Recovery And Post-Procedure Care

When interventional treatments such as stent placement, embolization, or aneurysm coiling are performed during DSA, recovery time increases significantly. The medical team will assess the patient's condition and determine the appropriate discharge timeline based on post-operative progress and any potential complications.

Preparation And Patient Instructions

Prior to the procedure, patients are advised to fast for several hours and empty their bladder and bowels to minimize discomfort. Remaining calm and cooperating with the medical team during the procedure is essential for ensuring a smooth and successful examination.
