I70.361
Atherosclerosis of unspecified type of bypass graft(s) of the extremities with gangrene, right leg
Clinical Classification Guidelines
Medical Intelligence & Overview
Atherosclerosis of a bypass graft in the extremities occurs when fatty deposits build up inside the blood vessels used to reroute blood flow, often following vascular surgery. When complications develop, such as gangrene, it indicates a serious impairment of blood supply, which can threaten limb viability. This condition specifically affects the right leg, involving an unspecified type of bypass graft, and is characterized by tissue death due to inadequate blood flow, leading to gangrene.
Causes & Symptoms
Clinical Causes: Progressive narrowing or blockage of the bypass graft caused by atherosclerotic plaque buildup Inadequate blood flow through the graft due to thrombosis or occlusion Infection at the graft site worsening blood flow issues Progression of peripheral arterial disease affecting the limb Poor management of underlying risk factors such as hypertension, diabetes, smoking, and high cholesterol
Key Symptoms: Severe pain in the affected leg, often worsening with activity or elevation Discoloration or darkening of the skin over the graft or affected area Swelling and coldness in the limb Loss of sensation or numbness in the toes or foot Development of open sores or ulcers that do not heal Presence of gangrene, characterized by tissue blackening and decay
Diagnostic & Treatment
Diagnosis Path: Physical assessment of the limb for signs such as coldness, discoloration, and tissue necrosis Doppler ultrasound to evaluate blood flow within the graft Angiography (contrast imaging) to visualize the graft patency and identify blockages Computed tomography (CT) angiography for detailed vascular assessment Laboratory tests to rule out infection and assess overall health
Treatment Protocols: Emergency surgical procedures such as bypass revision or removal of the graft if necessary Endovascular techniques like angioplasty or stenting to open occluded grafts Anticoagulant and antiplatelet medications to prevent clot formation Antibiotics if an infection is present Wound care including debridement and dressings for gangrenous tissue Amputation may be required if gangrene extends and limb salvage is no longer possible Management of underlying risk factors through lifestyle changes and medication
