Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]
Angiopathy is the generic term for a disease of the blood vessels (arteries, veins, and capillaries). [1] This also refers to the condition of damage or rupture of small blood vessels. The best known and most prevalent angiopathy is diabetic angiopathy , a common complication of chronic diabetes .
When there is a GSV thrombosis or other cause of insufficiency, the Giacomini vein can divert the blood flow to the SSV and from there to the popliteal vein. Where surgery, other than stripping or laser ablation is intended, the examiner will make reference to the blood flow direction in this vein, as it will be of importance. [39]
Vascular disease is a subgroup of cardiovascular disease. Disorders in this vast network of blood and lymph vessels can cause a range of health problems that can sometimes become severe, and fatal. [3] Coronary heart disease for example, is the leading cause of death for men and women in the United States. [5]
Urgent medical attention in this phase often features fluid resuscitation efforts, mainly the intravenous administration of saline solution plus hetastarch or albumin and colloids (to increase the remaining blood flow to vital organs like the kidneys), as well as glucocorticoids (steroids like methylprednisolone, to reduce or stop the capillary ...
This valvular incompetence combined with persistent venous obstruction from thrombus increases the pressure in veins and capillaries. Venous hypertension induces a rupture of small superficial veins, subcutaneous hemorrhage [7] and an increase of tissue permeability. That is manifested by pain, swelling, discoloration, and even ulceration.
Sickle cell disease is a group of inherited blood disorders, caused by a genetic abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [57] Under certain circumstances, this leads to the red blood cells adopting an abnormal sickle -like shape; with this shape, they are unable to deform as they pass through capillaries ...
Some health care workers prefer to use a syringe-needle technique for venipuncture. Sarstedt manufactures a blood-drawing system (S-Monovette) that uses this principle. [23] This method can be preferred on the elderly, those with cancer, severe burns, obesity, or where the veins are unreliable or fragile.
