Summary
This study explores surgical approaches for right-sided arteriovenous malformations (AVMs). Both contralateral and ipsilateral interhemispheric techniques successfully treated AVMs, preserving neurological function and venous drainage.
Area of Science:
- Neurosurgery
- Vascular Neurology
- Radiology
Background:
- Arteriovenous malformations (AVMs) in the interhemispheric region pose surgical challenges.
- Surgical intervention aims to prevent hemorrhage and neurological deficits.
Purpose of the Study:
- To illustrate and compare contralateral versus ipsilateral interhemispheric surgical approaches for right-sided interhemispheric AVMs.
- To evaluate the safety and efficacy of these surgical techniques.
Main Methods:
- Case study of two patients with right-sided interhemispheric AVMs.
- Surgical resection via contralateral and ipsilateral interhemispheric approaches.
- Intraoperative angiography to confirm AVM obliteration and venous drainage.
Main Results:
- Complete obliteration of AVMs was achieved in both cases.
- Patients remained neurologically intact postoperatively.
- Contralateral approach avoided right hemisphere retraction; ipsilateral approach preserved critical draining veins.
Conclusions:
- Both contralateral and ipsilateral interhemispheric approaches are effective for right-sided interhemispheric AVMs.
- Surgical approach selection should consider AVM location, feeding arteries, and venous drainage patterns.
- These techniques offer safe and effective AVM treatment with preserved neurological function.

Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

The operational amplifier, often referred to as an op-amp, is a multifaceted building block of a circuit. This electronic component functions like a voltage-controlled voltage source and can also be used to create a voltage- or current-controlled current source. The design of an operational amplifier enables it to execute mathematical operations when external components like resistors and capacitors are linked to its terminals. An op-amp has the capacity to sum signals, amplify a signal,...

The concept of real numbers includes all the values that can be represented on a continuous number line. The system began with basic counting values used for enumeration. It later expanded to include values that represent the absence of quantity and opposites of the counting values. When situations required expressing parts of a whole or dividing quantities evenly, values capable of representing such proportions were developed. When written using decimal notation, these values can end or repeat...

Vectors are physical quantities that have both magnitude and direction. The vector operations include addition, subtraction, and scalar multiplication.
A vector multiplied by a scalar value is called scalar multiplication. The result obtained is a new vector with a different magnitude. If the scalar is positive, the direction of the vector remains the same, but if it is negative, the direction of the vector is reversed. For example, the product of the mass and velocity yields the momentum.

Operant conditioning, a key concept in behavioral psychology, involves using reinforcement and punishment to alter the likelihood of a behavior being repeated. B.F. introduced this type of conditioning. Skinner focused on voluntary behaviors and the consequences that follow them, influencing whether these behaviors will be strengthened or diminished.
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...

The first order operators using the del operator include the gradient, divergence and curl. Certain combinations of first order operators on a scalar or vector function yield second order expressions. Second-order expressions play a very important role in mathematics and physics. Some second order expressions include the divergence and curl of a gradient function, the divergence and curl of a curl function, and the gradient of a divergence function.
