Anterior cerebral artery syndrome
ICD-10 G46.1 is a billable code used to indicate a diagnosis of anterior cerebral artery syndrome.
Anterior cerebral artery syndrome (ACAS) is a neurological condition resulting from ischemia or infarction in the territories supplied by the anterior cerebral artery (ACA). This syndrome is characterized by a range of symptoms, including contralateral hemiparesis, particularly affecting the leg more than the arm, and sensory loss. Patients may also exhibit behavioral changes, such as apathy or personality alterations, due to the involvement of the frontal lobe. Transient ischemic attacks (TIAs) may precede a full-blown stroke, serving as warning signs of potential cerebrovascular events. The ACA supplies blood to the medial portions of the frontal lobes and superior medial parietal lobes, making its occlusion particularly impactful on motor and cognitive functions. Stroke prevention strategies for patients at risk include lifestyle modifications, management of hypertension, diabetes, and hyperlipidemia, and the use of antiplatelet agents. Understanding the clinical presentation and risk factors associated with ACAS is crucial for timely diagnosis and intervention.
Detailed neurological examination findings, including motor and sensory assessments, and cognitive evaluations.
Patients presenting with unilateral weakness, sensory loss, or cognitive changes following a TIA or stroke.
Ensure clear documentation of the onset, duration, and resolution of symptoms to differentiate between TIA and stroke.
Accurate recording of patient history, symptom onset, and initial neurological assessments.
Patients arriving with acute onset of neurological deficits, requiring rapid assessment and intervention.
Timely documentation is critical for stroke protocols and potential thrombolytic therapy eligibility.
Used for follow-up visits for patients with ACAS to monitor recovery and manage risk factors.
Document the patient's history, examination findings, and any changes in treatment plans.
Neurologists should ensure comprehensive documentation of neurological assessments.
The primary symptoms include contralateral leg weakness, sensory loss, and potential cognitive changes due to frontal lobe involvement.
ACAS typically presents with more pronounced leg weakness compared to arm weakness, and cognitive changes may be more evident due to frontal lobe involvement.
