The most common cause of chronic venous insufficiency is reflux of the venous valves of superficial veins. [2] This may in turn be caused by several conditions: Deep vein thrombosis (DVT), that is, blood clots in the deep veins. Chronic venous insufficiency caused by DVT may be described as postthrombotic syndrome. DVT triggers an inflammatory ...
Peripheral vasoconstriction accounts for the cold extremities (hands and feet), increased heart rate, increased cardiac output (and associated chest pain). Eventually, there will be less perfusion to the kidneys, resulting in decreased urine output.
Venous insufficiency is the most common disorder of the venous system, and is usually manifested as either spider veins or varicose veins. Several treatments are available including endovenous thermal ablation (using radiofrequency or laser energy), vein stripping, ambulatory phlebectomy, foam sclerotherapy, laser, or compression.

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.
Vasculitis, peripheral arterial vascular disease, and lower extremity chronic venous insufficiency are the most frequent conditions to be taken into account during the differential diagnosis process. Peripheral artery diseases are diagnosed with the help of clinical signs, abnormal arterial Doppler ultrasound findings, and the ankle-brachial ...

Macroangiopathy may cause other complications, such as ischemic heart disease, stroke and peripheral vascular disease which contributes to the diabetic foot ulcers and the risk of amputation. In microangiopathy, the walls of the smaller blood vessels become so thick and weak that they bleed , leak protein , and slow the flow of blood through ...
Critical limb ischemia is diagnosed by the presence of ischemic rest pain, and an ulcers that will not heal or gangrene due to insufficient blood flow. [3] Insufficient blood flow may be confirmed by ankle-brachial index (ABI), ankle pressure, toe-brachial index (TBI), toe systolic pressure, transcutaneous oxygen measurement (TcpO2 ), or skin perfusion pressure (SPP).
