Blood pressure normalization post-jugular venous balloon angioplasty.

Area of Science:

• Neurology
• Vascular Medicine
• Autonomic Neuroscience

Background:

• Multiple sclerosis (MS) is associated with autonomic nervous system (ANS) dysfunction.
• Chronic cerebrospinal venous insufficiency (CCVI) is increasingly recognized in MS patients.
• The relationship between CCVI and ANS dysfunction in MS remains under investigation.

Purpose of the Study:

• To investigate the link between internal jugular vein (IJV) narrowing and ANS dysfunction in MS patients.
• To assess the impact of balloon angioplasty on blood pressure in MS patients with IJV narrowing and ANS dysfunction.

Main Methods:

• Screening of MS patients for IJV narrowing (≥50% stenosis) and ≥3 ANS dysfunction symptoms.
• Measurement of systolic and diastolic blood pressure pre- and post-IJV balloon angioplasty.

Main Results:

• 91% of screened MS patients had IJV narrowing and concurrent ANS dysfunction symptoms.
• Balloon angioplasty demonstrated a biphasic blood pressure response: increasing it in hypotensive patients and decreasing it in hypertensive patients.
• Observed gender differences in baseline blood pressure subcategories.

Conclusions:

• The co-occurrence of IJV narrowing and ANS dysfunction in MS suggests a potential relationship.
• IJV balloon angioplasty can correct blood pressure deviations in MS patients with CCVI.
• Further research is warranted to explore the association between blood pressure regulation and IJV narrowing in MS, and its impact on clinical outcomes.
