Summary
Leg vein treatments may improve orthostatic hypotension (OH) symptoms by reducing blood pressure drops and heart rate spikes. Further research is needed to understand the connection between venous insufficiency and OH.
Area of Science:
- Cardiology
- Vascular Medicine
- Nephrology
Background:
- Orthostatic hypotension (OH) causes are often unclear, despite being well-documented.
- Common causes include autonomic dysfunction, medications, and systemic diseases, but many cases remain idiopathic.
Purpose of the Study:
- To investigate the potential role of venous insufficiency in orthostatic hypotension.
- To assess the impact of venous ablative treatments on orthostatic vital signs.
Main Methods:
- Retrospective review of 646 patients with venous insufficiency from 2013-2019.
- Measurement of orthostatic vital signs (blood pressure, heart rate) before and after venous ablative procedures.
- Statistical regression analysis to evaluate changes in vital signs.
Main Results:
- Out of 178 patients with positive orthostatic hypotension, significant reductions in systolic blood pressure drop (p ≤ 0.001), diastolic blood pressure drop (p ≤ 0.001), and heart rate increase (p ≤ 0.001) were observed post-treatment.
- Venous ablative treatments significantly improved orthostatic vital sign fluctuations.
Conclusions:
- Venous ablative treatments show promise in improving orthostatic vital signs.
- Venous assessment and treatment may be a therapeutic option for resistant orthostatic intolerance.
- Further investigation into venous insufficiency in OH is warranted to elucidate underlying mechanisms.

01:26Varicose Veins I: Introduction
28
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...

1.5K
Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

7.2K
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...

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...

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,...

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...
