Abstract:
A 74-year-old woman underwent abdominal computed tomography for screening, and a right large aneurysmal-type renal arteriovenous fistula (AVF) was found incidentally. The venous sac of the renal arteriovenous fistula was enlarged, and coil embolization was considered. To prevent severe complications such as coil migration, pulmonary embolism, and rupture during procedure, coil embolization was approached via both the feeding artery and the draining vein simultaneously, with balloon occlusion of the feeding artery. It was accomplished successfully, and the patient could discharge without complication.

Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...
Renal Clearance
Renal clearance refers to the volume of plasma cleared of a specific substance, such as creatinine, per unit of time. To measure clearance, urine samples are collected over a 24-hour period during each bladder voiding, followed by a single blood sample at the...
