ICD-10: I97.81

Intraoperative cerebrovascular infarction, classified under ICD-10 code I97.81, refers to a specific type of cerebrovascular accident that occurs during a surgical procedure. This condition is characterized by the interruption of blood flow to the brain, leading to tissue damage and potential neurological deficits. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description

Definition

Intraoperative cerebrovascular infarction is defined as an ischemic event that occurs during surgery, particularly when procedures involve the brain or major blood vessels supplying the brain. This condition can result from various factors, including embolism, thrombosis, or hemodynamic instability during the surgical process.

Etiology

The causes of intraoperative cerebrovascular infarction can be multifactorial:
- Embolic Events: Fragments of thrombus or plaque can dislodge during surgery, traveling to cerebral arteries and occluding blood flow.
- Hypoperfusion: Significant drops in blood pressure or blood flow during surgery can lead to inadequate perfusion of brain tissue.
- Surgical Manipulation: Direct manipulation of blood vessels or surrounding tissues can cause vascular injury or compromise blood flow.

Risk Factors

Several risk factors may increase the likelihood of intraoperative cerebrovascular infarction:
- Pre-existing Vascular Disease: Patients with a history of stroke, transient ischemic attacks (TIAs), or significant carotid artery stenosis are at higher risk.
- Cardiac Conditions: Arrhythmias or heart failure can contribute to embolic events during surgery.
- Surgical Complexity: High-risk surgeries, particularly those involving the heart, neck, or brain, carry a greater risk of cerebrovascular complications.

Clinical Presentation

Symptoms

Symptoms of intraoperative cerebrovascular infarction may not be immediately apparent during surgery but can manifest as:
- Sudden weakness or paralysis on one side of the body.
- Speech difficulties or confusion.
- Visual disturbances.
- Loss of coordination or balance.

Diagnosis

Diagnosis typically involves:
- Neurological Assessment: Immediate evaluation of neurological function during or after surgery.
- Imaging Studies: CT or MRI scans may be performed to confirm the presence of an infarction and assess the extent of brain damage.

Management and Treatment

Immediate Interventions

Management of intraoperative cerebrovascular infarction focuses on restoring blood flow and minimizing neurological damage:
