Summary
This study on elderly patients with chronic venous insufficiency (CVI) found that lipid peroxidation and inflammation decrease with ulcer formation, alongside tissue hypoxia. Optimized treatment should address venous hypertension, microcirculation, and reperfusion injury.
Area of Science:
- Vascular Surgery
- Geriatric Medicine
- Biochemistry
Background:
- Chronic venous insufficiency (CVI) affects elderly populations, often leading to nonhealing trophic ulcers.
- Understanding the biochemical changes in tissues with CVI is crucial for effective treatment.
Purpose of the Study:
- To analyze treatment outcomes in elderly patients (over 80) with CVI and trophic ulcers.
- To investigate the relationship between lipid peroxidation, antioxidant defense, tissue hypoxia, and inflammation in CVI patients.
Main Methods:
- Phlebectomy (full or partial) was performed on patients with CVI.
- Tissue oxygen tension (TepO2) was measured using a TCM-3 outfit.
- Lipid peroxidation and antioxidant defense parameters were assessed in blood samples.
Main Results:
- Lipid peroxidation was highest in CVI patients without ulcers (CEAP C3-5) and decreased with ulcer formation (CEAP C6).
- Tissue hypoxia (TepO2 1.7-7.0 mm Hg) was associated with varicose ulcers.
- Reduced antioxidant defense and active inflammation were observed in patients with trophic ulcers.
Conclusions:
- Treatment optimization for elderly CVI patients requires addressing venous hypertension, microcirculatory disorders, and local hypoxia.
- Postoperative reperfusion attenuation is critical for managing trophic ulcers in this demographic.

01:31Diabetic Foot Ulcer
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
01:30Venous Thrombosis IV: Nursing Management
Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...
01:27Assessment of the Cardiovascular System III: Palpation
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

01:26Varicose Veins I: Introduction
Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...
01:30Venous Thrombosis I: Introduction
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
01:23Hypoxia
Hypoxia is a medical condition characterized by an inadequate oxygen supply to body tissues. It typically manifests as a bluish discoloration of the skin and mucosae, especially in fair-skinned individuals, when hemoglobin (Hb) saturation drops below 75%.
Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...
