Fibrinolytic defect and chronic low-back pain

Area of Science:

• Medical Research
• Hematology
• Neurosurgery

Background:

• Chronic low-back pain affects a significant population, often with associated leg pain.
• Fibrinolytic activity plays a role in vascular health and may be implicated in pain conditions.
• Arachnoiditis, inflammation of the arachnoid mater, is a known complication that can cause persistent pain.

Purpose of the Study:

• To investigate the prevalence of fibrinolytic defects in patients with chronic low-back pain.
• To determine the association between fibrinolytic defects and the presence of arachnoiditis.
• To evaluate the utility of a venous occlusion test in identifying fibrinolytic defects.

Main Methods:

• Fifty-five patients with chronic low-back pain underwent a 10-minute venous occlusion test to assess fibrinolytic activity.
• Diagnosis of arachnoiditis was confirmed through direct surgical observation or advanced imaging (myelography and CT scan).
• Fibrinolytic activity was measured following the occlusion test.

Main Results:

• A fibrinolytic defect was identified in 45% (25/55) of patients with chronic low-back pain.
• The prevalence of fibrinolytic defects was significantly higher in patients with arachnoiditis, at 75% (18/24).
• The venous occlusion test demonstrated effectiveness in enhancing the detection sensitivity for fibrinolytic defects.

Conclusions:

• Fibrinolytic defects are not uncommon in individuals experiencing chronic low-back pain.
• There is a strong correlation between fibrinolytic defects and the presence of arachnoiditis.
• The venous occlusion test is a valuable tool for improving the diagnosis of fibrinolytic defects in this patient group.
