If a patient's lymphatic system is severely compromised following a radical mastectomy, which consequence follows regarding fluid filtration at the capillary level in the affected limb?

💡 Explanation

Edema arises from fluid accumulation. A compromised lymphatic system disrupts interstitial fluid drainage, which normally removes filtered fluid from capillaries; because lymphatic drainage is reduced, interstitial hydrostatic pressure increases, therefore fluid accumulates in the tissues, rather than being returned to circulation.
