A limb infarction is an infarction of an arm or leg.
Causes
Arterial embolisms commonly lodge in the extremities. Another cause of limb infarction is skeletal muscle infarction as a rare complication of long standing, poorly controlled diabetes mellitus.[1]
Symptoms
Early symptoms of an arterial embolism in the arms or legs appear as soon as there is ischemia of the tissue, even before any frank infarction has begun. Such symptoms may include:
- Coldness in a leg, arm, hand or fingers[2][3]
- Decreased or no pulse in an arm or leg beyond the site of blockage[2][3]
- Pain in the affected area[2][3]
- Muscle spasm in the affected area[2]
- Numbness and tingling in an arm or leg[2][3]
- Paleness (pallor)[3][2] of the skin of the arm or leg
- Muscle weakness of an arm or leg,[2][3] possibly to the grade of paralysis[3]
Later symptoms are closely related to infarction of the tissue supplied by the occluded artery:
- Blisters of the skin in the affected area[2]
- Shedding of skin (desquamation)[2]
- Skin erosion (ulceration)[2]
- Discoloration (mottling[3], cyanosis[3] or darkening[2]) of the skin following necrosis. The discoloration usually has a distinct demarcation at the blockage.[3]
A major presentation of diabetic skeletal muscle infarction is painful thigh or leg swelling.[1]
Diagnosis
In addition to evaluating the symptoms described above, magnetic resonance imaging (MRI) is the preferred test for diagnosing skeletal muscle infarction.[1]
Treatment
In the legs, below the inguinal ligament, percutaneous aspiration thrombectomy is a rapid and effective way of removing thrombi in thromboembolic occlusions.[4] In the arms, balloon thrombectomy using a Fogarty catheter is an effective treatment.[5] Because of the high recurrence rates of thromboembolism, it seems necessary to administer anticoagulant therapy as well.[5]
