Intracranial Aneurysm Model for Detachable Coil Testing.
Summary
Researchers developed a new animal model for intracranial aneurysms using swine carotid arteries. This model is suitable for testing detachable coils, particularly for histopathology, offering a valuable tool for evaluating new treatments.
Area of Science:
- Vascular Surgery
- Biomedical Engineering
- Animal Models
Background:
- Intracranial aneurysms are life-threatening vascular diseases with challenging treatment options.
- Detachable coils are a standard treatment, but their efficacy requires further evaluation.
- Existing evaluation methods, including animal models, have limitations.
Purpose of the Study:
- To develop and validate a novel animal model for intracranial aneurysms.
- To assess the suitability of this model for testing detachable coils, focusing on histopathological analysis.
Main Methods:
- Sidewall aneurysms were surgically created on the common carotid arteries of Landrace-Yorkshire-Duroc swine.
- External jugular vein grafts were utilized to construct the aneurysm sac.
- End-to-side anastomosis techniques were employed for vessel connection.
- Ten aneurysms were successfully created in five swine without perioperative mortality.
Main Results:
- A reproducible swine model for intracranial aneurysms was established.
- The model demonstrated no perioperative complications in the initial cohort.
- The created aneurysms were deemed suitable for further investigation, particularly for histopathological assessment.
Conclusions:
- The developed swine aneurysm model is appropriate for evaluating detachable coils.
- This model offers significant potential for histopathological studies related to aneurysm treatment.
- Further research using this model can advance the understanding and treatment of intracranial aneurysms.

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...

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...

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

296
Compendial dissolution methods are standardized procedures defined by pharmacopeias to evaluate the rate at which a drug dissolves in a specific medium. These methods ensure batch-to-batch consistency, enable quality control, and support the prediction of drug bioavailability. They are critical for both immediate and modified-release drug products.The apparatuses used for dissolution testing differ in their design and mechanical function, but all aim to simulate the physiological environment of...

Various dissolution methods are utilized to assess a drug’s dissolution rate, including the flow-through cell, paddle-over-disk, cylinder, and reciprocating disk methods.The flow-through cell apparatus (USP (United States Pharmacopeia) method 4) comprises a reservoir for the dissolution medium and a pump that propels the medium through the cell containing the test sample. This method is crucial for assessing modified-release dosage forms with minimally soluble active ingredients,...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
