Abstract

Objective:

The aim: With the help of biochemical and morphological methods of investigation to identify the causes of a false postoperative recurrence of varicose veins after the EVLC.

Patients And Methods:

Materials and methods: In 173 patients with varicose veins of the lower extremities, the level of markers of endothelial dysfunction was determined: P-selectin, E-selectin, tissue plasminogen activator, endothelin-1, adhesion molecules of type 1 vascular endothelium (sVCAM-1-soluble vascularcellularmolecula), circulating endothelial cells (CEC) before surgery (EVLC), on the 10th and 60th day of the postoperative period.At the same time, a morphological and electron microscopic examination of the state of the deep venous system in 31 patients with varicose vein disease of the lower extremities who died from acute heart failure, was performed.

Results:

Results: Increased values of markers of endothelial dysfunction in patients with varicose veins of the lower extremitiesbefore surgery of EVLC were established. We found that, despite the operation, the parameters of endothelial dysfunction decrease, but in the remote postoperative period do not come to the norm. Morphological and electron microscopic studies of the deep vein wall revealed pathomorphological changes in all of their layers, especially the endothelial layer. At the heart of the development of endothelial dysfunction in the postoperative period, the leading role belongs to changes in mitochondria.

Conclusion:

Conclusions: 1. Based on our research, we can state that there are significant pathomorphological and pathophysiological changes in the deep venous system of the lower extremities in conditions of varicose vein disease. 2. The initiator of postoperative relapse of varicose veins are structural changes in the wall of deep veins with a violation of the integrity of the endothelial lining, contributing to the absorption of plasma and leukocyte contents from the blood stream in the interstitium, with the following pathological changes in the layers of deep veins.Such changes are the basis for the manifestations of endothelial dysfunction in the postoperative period.

Varicose Veins II: Diagnostic Studies and Interprofessional Care

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Varicose Veins I: Introduction

Varicose 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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Vascular Spasm

Vascular Spasm

The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last...

Venous Return

Venous Return

The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

Esophageal Varices-II: Clinical Features and Management

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...
