What is hand ischemia?

Hand ischemia is a rare but potentially devastating complication of radial artery cannulation for arterial monitoring. The causes and ultimate outcomes of hand ischemia after radial artery cannulation are unclear.

What causes hand ischemia?

What causes hand ischemia? One cause of hand ischemia is a condition called Raynaud’s disease (or Raynaud’s phenomenon), which affects about 5% of people in the United States. There are two kinds of Raynaud’s—primary and secondary.

Is acute limb ischemia life-threatening?

Background: Acute limb ischemia represents a clinical emergency with eventual limb loss and life-threatening consequences. It is characterized by a sudden decrease in limb perfusion. Acute ischemia is defined as a duration of symptoms for less than 14 days.

What ischemia means?

Ischemia is a condition in which the blood flow (and thus oxygen) is restricted or reduced in a part of the body. Cardiac ischemia is the name for decreased blood flow and oxygen to the heart muscle.

How is acute limb ischemia treated?

Treatment methods for ALI include surgical treatment (such as thromboembolectomy and bypass surgery), endovascular treatment (such as catheter-directed thrombolysis [CDT], percutaneous thrombus aspiration, and stent placement), and hybrid treatment that combines both therapies.

How painful is ischemia?

Ischemic rest pain is classically described as a burning pain in the ball of the foot and toes that is worse at night when the patient is in bed. The pain is exacerbated by the recumbent position because of the loss of gravity-assisted flow to the foot.

What is the treatment for ischemia?

The goal of myocardial ischemia treatment is to improve blood flow to the heart muscle. Depending on the severity of your condition, your doctor may recommend medications, surgery or both.

How do you fix ischemia?

Treatment for myocardial ischemia involves improving blood flow to the heart muscle. Treatment may include medications, a procedure to open blocked arteries (angioplasty) or bypass surgery.

What causes acute ischemia of the hand?

Acute ischemia of the hand may occur following laceration of the brachial, radial, and ulnar arteries.

What tests are used to diagnose ischemia of the hand?

Fifty consecutive patients with acute and chronic ischemia of the hand were investigated by Allen testing, Doppler ultrasound, digital plethysmography, and angiography over a 4-year period.

Which medications are used to treat chronic ischemia of the hand?

Patients with chronic ischemia of the hand were maintained on nifedipine, 30 to 60 mg daily, and pentoxifylline, 1200 mg daily. Seven patients underwent digital sympathectomy and 14 patients underwent microsurgical revascularization as prophylactic procedures for chronic digital ischemia.

What is ischemia?

What is ischemia? Ischemia is any reduction in blood flow resulting in decreased oxygen and nutrient supplies to a tissue. Ischemia may be reversible, in which case the affected tissue will recover if blood flow is restored, or it may be irreversible, resulting in tissue death.
