Insights

A novel surgical approach successfully treated a giant ruptured paraclinoid aneurysm and bilateral internal carotid artery dissections. This combined treatment prevented cerebral ischemia and excluded the aneurysm from circulation.

Area of Science:

  • Neurosurgery
  • Vascular Neurology
  • Interventional Neuroradiology

Background:

  • Giant ruptured paraclinoid aneurysms with bilateral internal carotid artery dissections (CAD) pose significant treatment challenges.
  • Paraclinoid internal carotid artery (ICA) aneurysms are complex cases for vascular neurosurgeons.
  • Management of carotid artery dissections remains debated, with surgery or endovascular treatment indicated for multivessel dissections or subarachnoid hemorrhage (SAH).

Observation:

  • A 35-year-old woman presented with SAH due to a ruptured paraclinoid aneurysm in the left ICA.
  • The patient also had concurrent dissections in both internal carotid arteries.
  • A high-flow extracranial-intracranial arterial graft bypass followed by left ICA trapping was performed.

Findings:

  • The procedure successfully excluded the aneurysm from cerebral circulation.
  • Embolic events from the left ICA were prevented.
  • Conservative management with anticoagulants and antiplatelets effectively treated the right internal carotid artery dissection.

Implications:

  • Treating only the aneurysm without addressing concurrent ICA dissection may be insufficient.
  • Simultaneous management of giant ruptured paraclinoid aneurysms and bilateral ICA dissection is achievable with bypass and trapping techniques.
  • This case highlights a viable strategy for complex cerebrovascular conditions.

Internal Energy02:00

Internal Energy

The total of all possible kinds of energy present in a substance is called the internal energy (U), sometimes symbolized as E. Suppose a system with initial internal energy, Uinitial, undergoes a change in energy (transfer of work or heat), and the final internal energy of the system is Ufinal. Change in internal energy equals the difference between Ufinal and Uinitial.

Internal Energy01:29

Internal Energy

The internal energy of a thermodynamic system is the sum of the kinetic and potential energies of all the molecules or entities in the system. The kinetic energy of an individual molecule includes contributions due to its rotation and vibration, as well as its translational energy. The potential energy is associated only with the interactions between one molecule and the other molecules of the system. Neither the system's location nor its motion is of any consequence as far as the internal...

Internal Receptors01:31

Internal Receptors

Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

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...

International System of Units

The International System of Units, known as the SI system, is a universally accepted measurement system recognized and used worldwide. The SI system is based on a set of three base units considered absolute, and their values do not change with location. These base units are meters, kilograms, and seconds.
Prefixes are used to define both larger and smaller quantities in the SI system. For example, milli, micro, and nano define smaller quantities, while kilo, mega, and giga are used to define...

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
