Abstract:
Lumbar artery pseudoaneurysms have previously been described as rare iatrogenic complications following percutaneous interventional procedures involving the flanks. We describe a case of a 71-year-old man who became unstable and dropped 3 grams of hemoglobin within 24 hours following renal biopsy. A post-biopsy hemorrhage was suspected, and a pseudoaneurysm of his second right lumbar (L2) artery was found on computed tomography angiogram (CTA). Successful coil embolization was performed in the right L2 artery. This case discusses the diagnostic and therapeutic challenges of this unusual complication as well as the anatomical and technical factors involved in the embolization of the lumbar arteries.

01:17Factors 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...
01:23Renal 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...
01:08Renal Drug Clearance: Comparison Between Renal Excretion Methods
Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...

Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
