Insights

Modern cerebral angiography is generally safe, with rare but serious complications like groin hematoma and neurologic deficits. Careful patient selection and training can minimize risks associated with this diagnostic procedure.

Area of Science:

  • Neurology
  • Radiology
  • Vascular Medicine

Background:

  • Cerebral angiography is a key diagnostic tool for cerebrovascular diseases.
  • Assessing complication rates is crucial for patient safety and procedural refinement.

Purpose of the Study:

  • To evaluate the incidence and types of minor and major complications in modern cerebral angiography.
  • To identify risk factors and outcomes associated with cerebral angiography procedures.

Main Methods:

  • Retrospective analysis of 644 consecutive cerebral angiographic cases.
  • Detailed review of patient records focusing on documented complications.

Main Results:

  • Groin hematoma (1.55%) was the most frequent complication.
  • Neurologic complications occurred in 0.62% of cases, including one permanent hemiplegia (0.16%).
  • Contrast-induced nephropathy (5%) and one death from air emboli (0.16%) were also reported.

Conclusions:

  • Neurologic complications from cerebral angiography are infrequent but significant.
  • Careful patient selection and enhanced training are vital for minimizing procedural risks.
  • While risks are low, severe outcomes like permanent disability or death cannot be entirely eliminated.

Cerebral Hemispheres01:05

Cerebral Hemispheres

The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...
