Insights

Coil embolization for large aneurysms showed reasonable safety but continuous long-term risks of recanalization and thromboembolism, particularly with incomplete occlusion. Careful follow-up is crucial for patients with incomplete aneurysm occlusion.

Area of Science:

  • Neurosurgery
  • Interventional Radiology
  • Vascular Neurology

Background:

  • Large or giant aneurysms pose significant risks.
  • Endovascular coil embolization is a treatment option.
  • Long-term outcomes require thorough evaluation.

Purpose of the Study:

  • To assess the immediate and long-term efficacy of coil embolization for large/giant aneurysms.
  • To evaluate the safety profile of this endovascular procedure.
  • To identify factors influencing recurrence and thromboembolic events.

Main Methods:

  • Retrospective review of 150 cases of large/giant aneurysms treated with coil embolization.
  • Analysis of medical records and imaging findings.
  • Statistical evaluation for prognostic factors of recurrence and delayed thromboembolism.

Main Results:

  • Procedure-related symptomatic complications occurred in 3.3% of patients.
  • The annual recurrence rate was 4.6% per year.
  • Incomplete occlusion was the sole factor associated with recurrence (p=0.008) and delayed infarction.

Conclusions:

  • Coil embolization offers reasonable immediate safety but carries continuous long-term risks.
  • Incomplete occlusion is linked to recurrence and delayed thromboembolic complications.
  • Close patient monitoring is essential for incomplete occlusions to detect delayed events.

Incomplete Dominance01:43

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Predicting Reaction Outcomes02:24

Predicting Reaction Outcomes

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Aneurysm I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Outcomes of Glycolysis01:13

Outcomes of Glycolysis

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Guidelines for Writing Outcome01:11

Guidelines for Writing Outcome

When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
