A person with a two hour history of phlegmasia cerulea dolens (left leg, right side of image) Phlegmasia cerulea dolens (PCD) (literally: 'painful blue inflammation'), not to be confused with preceding phlegmasia alba dolens , is an uncommon severe form of lower extremity deep venous thrombosis (DVT) that obstructs blood outflow from a vein.
Superficial vein thrombosis (SVT) extension to the deep vein system and/or recurrence of SVT. Suppurative thrombophlebitis is suspected when erythema extends significantly beyond the margin of the vein and is likely to be associated with significant fever. If suspected, antibiotic treatment, surgical drainage, and potentially vein excision are ...
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.
External bleeding is generally described in terms of the origin of the blood flow by vessel type. The basic categories of external bleeding are: Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation.
A hematoma, also spelled haematoma, or blood suffusion is a localized bleeding outside of blood vessels, due to either disease or trauma including injury or surgery [1] and may involve blood continuing to seep from broken capillaries.
Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities).

The major tissues affected are nerves and muscles, where irreversible damage starts to occur after 4–6 hours of cessation of blood supply. [4] Skeletal muscle, the major tissue affected, is still relatively resistant to infarction compared to the heart and brain because its ability to rely on anaerobic metabolism by glycogen stored in the cells may supply the muscle tissue long enough for ...
