Insights

A novel technique, extracranial stent retriever assisted vacuum-locked extraction (eSAVE), effectively retrieves clots in acute tandem lesions. This method offers a new option for treating complex carotid artery blockages.

Area of Science:

  • Neurology
  • Vascular Surgery
  • Interventional Radiology

Background:

  • Atherosclerotic plaques in the internal carotid artery can rupture, forming clots.
  • Extra-/intracranial tandem lesions present complex treatment challenges.
  • Stent-assisted balloon angioplasty is a common treatment for these lesions.

Observation:

  • A technique called "stent retriever assisted vacuum-locked extraction" (SAVE) was initially developed for intracranial clot retrieval.
  • This study adapted the SAVE method for extracranial thrombus retrieval in tandem lesions.

Findings:

  • The adapted method, termed extracranial SAVE (eSAVE), was successfully applied.
  • eSAVE provides a strategy for removing extracranial thrombi in acute tandem lesions.

Implications:

  • The eSAVE method could become a valuable addition to the treatment armamentarium for acute tandem lesions.
  • This technique may improve outcomes for patients with complex carotid artery disease.
  • Further research is warranted to establish the full potential and safety of eSAVE.

Retrieval01:12

Retrieval

Retrieval is the process of getting information out of memory storage and back into conscious awareness. This ability is essential for daily tasks like brushing hair and teeth, driving to work, and performing job duties. Retrieval occurs in three ways: recall, recognition, and relearning.
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...

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...

ER Retrieval Pathway01:45

ER Retrieval Pathway

In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...

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.

Clot Retraction and Fibrinolysis01:16

Clot Retraction and Fibrinolysis

After a fibrin clot is formed, the next step is clot retraction, a vital process facilitated by platelet contractile proteins, such as actin and myosin. These proteins pull the fibrin strands closer together and condense the clot. This action reduces the size of the clot, creating a smaller, denser structure that effectively seals off the damaged vessel. Clot retraction consolidates the clot and helps with wound healing by bringing the edges of the damaged blood vessel closer together.
