The same classification method can be used for both primary lymphedema pathophysiology secondary lymphedema The International Society of Lymphology Lymphedema pathophysiology Staging System is based solely on subjective symptoms, making it prone to substantial observer bias.

Imaging modalities have been suggested as useful adjuncts to the ISL staging to clarify the diagnosis.

The lymphedema expert Dr. Spontaneously reversible on elevation. Non-spontaneously reversible on elevation. Gross increase in volume and circumference of Grade 2 lymphedema, lymphedema pathophysiology eight stages of severity given below based lymphedema pathophysiology clinical assessments.

Lymphoedema: pathophysiology and classification.

With the assistance of medical imaging apparatus, such as MRI or CTstaging can be established by the physician, and lymphedema pathophysiology or medical interventions may be applied: The lymphatic vessels have sustained some damage that lymphedema pathophysiology not yet apparent.

Transport capacity is sufficient for the amount of lymph being removed.


Lymphedema is not present. Swelling increases during the lymphedema pathophysiology and disappears overnight as the patient lies flat in bed. Tissue is still at the pitting stage: Usually upon waking in the morning, the limb or affected area is normal or almost normal lymphedema pathophysiology size.

Treatment is lymphedema pathophysiology necessarily required at this point. Swelling is not reversible overnight, and does not disappear without proper management. The tissue now has a spongy consistency and is considered non-pitting: Fibrosis found lymphedema pathophysiology Stage 2 lymphedema marks the beginning of the hardening of the limbs and increasing size.


Swelling is irreversible and usually the limb s or affected area become increasingly large. The tissue is hard fibrotic and unresponsive; some patients consider undergoing reconstructive surgery, called "debulking".

This lymphedema pathophysiology controversial, however, since the risks may outweigh the benefits and the further lymphedema pathophysiology done to the lymphatic system may in fact make the lymphedema worse.

The pathophysiology of lymphedema.

The size and circumference of the affected limb s become noticeably large. Bumps, lumps, or protusions also called knobs on the skin begin to appear. The affected limb s become grossly large; one or more deep skin folds is prevalent among patients in this stage.

Knobs of small lymphedema pathophysiology or small rounded sizes cluster together, giving mossy-like shapes on the limb. Mobility of the patient becomes lymphedema pathophysiology difficult. The patient becomes handicapped, and is unable to independently perform daily routine activities such as walking, bathing and cooking.

The pathophysiology of lymphedema.

Assistance from the family and health care system is needed. Presented below are upper and lower extremity lymphedema between stages 1 to 4: Severity of upper extremity lymphedema in different stages Severity of lower extremity lymphedema in different stages Other classification methods[ edit ] Grades[ edit ] Lymphedema pathophysiology can also be lymphedema pathophysiology by its severity usually referenced to a healthy extremity: Involves the distal parts such as a forearm and hand or a lower leg and foot.

Sometimes both arms or both legs swell.


Lymphedema is most commonly caused by the removal of or damage to your lymph nodes as a part of cancer treatment. It results from a blockage in lymphedema pathophysiology lymphatic system, which is part of your immune system.

The blockage prevents lymph fluid from draining well, and the fluid buildup leads to swelling. While there is presently no cure for lymphedema, it can be managed with early diagnosis and diligent lymphedema pathophysiology of your affected limb.
