Insights

Balloon angioplasty effectively treated cerebral vasospasm in two preschool children after subarachnoid hemorrhage. This minimally invasive procedure showed promising results for pediatric patients, warranting further investigation.

Area of Science:

  • Pediatric Neurology
  • Interventional Neuroradiology
  • Neurosurgery

Background:

  • Subarachnoid hemorrhage can lead to cerebral vasospasm and delayed cerebral ischemia, increasing patient morbidity and mortality.
  • Balloon angioplasty (PTA) is a known treatment for vasospasm in adults, but data in preschool-aged children are limited.
  • Pediatric cerebral vessels present unique challenges due to smaller diameters and fragility, potentially increasing complication risks.

Purpose of the Study:

  • To evaluate the safety and efficacy of balloon angioplasty (PTA) for treating cerebral vasospasm in preschool children.
  • To assess the role of PTA as a treatment modality in this specific pediatric population.

Main Methods:

  • Balloon PTA was performed in two pediatric patients (3 and 4 years old).
  • Both patients had aneurysmal subarachnoid hemorrhage complicated by delayed cerebral ischemia.

Main Results:

  • The balloon PTA procedures were performed without complications in both cases.
  • Both patients survived and remained free of new infarctions.

Conclusions:

  • Balloon angioplasty for proximal vasospasm may enhance clinical outcomes in select pediatric patients.
  • Further research is necessary to identify optimal patient candidates, materials, and techniques for pediatric PTA.

Anatomy of the Brain: Ventricles

There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
Development of Blood Vessels01:07

Development of Blood Vessels

The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...
