Renal pseudoaneurysm as a cause of hematuria in a colt.

Abstract: An 8-month-old Arabian-warmblood cross colt was evaluated for overt hematuria. The horse was severely anemic on presentation. A unilateral intrarenal vascular anomaly with unilateral pyelonephritis was diagnosed. Nephrectomy was attempted but was unsuccessful, and postmortem examination demonstrated the presence of an intrarenal pseudoaneurysm. Un poulain arabe de race croisée âgé de 8 mois a été évalué pour une hématurie patente. Le cheval était gravement anémique à la présentation. Une anomalie vasculaire unilatérale intrarénale avec une pyélonéphrite unilatérale a été diagnostiquée. Une néphrectomie a été tentée sans succès et l’examen postmortem a démontré la présence d’un pseudoanévrisme intrarénal. (Traduit par Isabelle Vallières)

This research article investigates a case of an 8-month-old Arabian-warmblood cross colt suffering from severe anemia and overt hematuria caused by the presence of intrarenal pseudoaneurysm and unilateral pyelonephritis, conditions diagnosed during clinical examination and confirmed postmortem.

Study Overview

  • The study presents a detailed case study of an 8-month-old Arabian-warmblood cross colt, which was observed to have overt hematuria and severe anemia.
  • Through careful evaluation and investigation, the colt was found to be suffering from an unusual case of a unilateral intrarenal vascular anomaly along with unilateral pyelonephritis.
  • A surgical intervention, in the form of a nephrectomy, was attempted to treat the condition but proved to be unsuccessful.
  • A postmortem examination of the colt confirmed the presence of an intrarenal pseudoaneurysm, a rare and serious condition that could have been the underlying cause of these observed symptoms.

Hematuria and Severe Anemia in the Colt

  • Hematuria, the presence of blood in urine, was the initial observable symptom in the colt, leading to further investigations.
  • The colt was also severely anemic, indicating a significant loss of red blood cells, probably due to the hematuria.
  • This combination of symptoms suggested a significant health issue, requiring further examination and diagnostics to determine the exact cause.

Diagnosis and Surgical Attempt

  • Upon examination, the colt was diagnosed with a unilateral intrarenal vascular anomaly – a rare condition involving abnormal blood vessel formation in one of the kidneys, along with unilateral pyelonephritis – an inflammation of the kidney usually due to a bacterial infection.
  • A surgical procedure, a nephrectomy, which involves removal of the affected kidney was attempted, but it was unsuccessful due to the severity and complexity of the conditions.

Postmortem Findings

  • A postmortem examination revealed the presence of an intrarenal pseudoaneurysm, which is essentially a false aneurysm within the kidney.
  • This condition involves the formation of a bulging blood vessel due to a leak in the arterial wall, which can lead to serious complications, including blood clots, rupture, and severe internal bleeding, potentially explaining the severe anemia and hematuria observed in the colt.
  • This finding further emphasized the severity and complexity of the colt’s health condition, and potentially provided significant insights for similar future cases.
