Chronic venous ulcers are painful and debilitating. Even with treatment, recurrences are common if venous hypertension persists. Nearly 60% develop phlebitis which often progresses to deep vein thrombosis in more than 50% of patients. The venous insufficiency can also lead to severe hemorrhage.
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.
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.

Treatment of dysautonomia can be difficult; since it is made up of many different symptoms, a combination of drug therapies is often required to manage individual symptomatic complaints. In the case of autoimmune neuropathy, treatment with immunomodulatory therapies is done. If diabetes mellitus is the cause, control of blood glucose is ...
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 ...
This sympathetic response is to release epinephrine and norepinephrine, which results in peripheral vasoconstriction (reducing size of blood vessels) in order to conserve the circulating fluids for organs vital to survival (i.e. brain and heart). Peripheral vasoconstriction accounts for the cold extremities (hands and feet), increased heart ...

Edema of the lower extremities (peripheral edema), caused by an increase in the venous blood pressure. Tachycardia. This is caused by the decreased preload and subsequent decreased cardiac output, and leads to a compensatory heart rate increase. In pregnant women, signs of fetal hypoxia and distress may be seen in the cardiotocography.
