The 5 Ps of Acute Limb Ischemia New York, NY

The 5 Ps of Acute Limb Ischemia


Acute limb ischemia is caused by a sudden decrease in blood flow to the hands and feet. While this type of ischemia is usually because of chronic peripheral artery disease, it can also occur in relatively healthy blood vessels through trauma or other clot formations. Unlike chronic ischemia, which develops slowly over time, acute ischemia occurs rapidly and is an emergency.

Five Signs of Acute Limb Ischemia

The telltale sign of limb ischemia is cold, mottled skin with a red, blue or purple coloring. The additional signs are:

  1. Pain. Your affected limb may hurt even if you lay down, and it may hurt more to elevate the limb. The pain may be severe enough that your clothes touching your skin will be uncomfortable.
  2. Pulse. There may be little to no pulse in the affected limb. It will depend on which part of the vascular system is blocked, and if there are any other major blood vessels serving the area.
  3. Pale. Due to the lack of blood flow, the limb will be very pale compared to the rest of your skin.
  4. Paresthesia. You may have tingling or a ‘pins and needles’ sensation.
  5. Paralysis. The complete inability to move all or part of the affected limb.

Treatment Options

Your specialist will evaluate your limb to determine which steps should be taken and how quickly the medical team needs to act. Since lack of blood flow can cause permanent damage or loss of the limb, your specialist may order heparin to break up the clot. They may also perform a thrombectomy or arterial surgery to remove the clot.

Acute Limb Ischemia Is an Emergency

If you believe you are experiencing acute limb ischemia, you must seek treatment immediately. The faster you receive treatment, the more likely your limb can be saved. If you have intermittent symptoms of limb ischemia, a specialist should evaluate you before the situation becomes an emergency.

Dr. Benvenisty was excellent and helped us with my husband's extensive leg swelling related to diabetes. We had another specialist who didn't help us last year. We're planning to stay with Dr. Benvenisty now! He's detailed oriented, matter-of-fact and friendly. An excellent doctor I would strongly recommend.


Dr. Benvenisty treated my mother in the ER during this time of the covid outbreak. He was a part of a fantastic team of doctors that were brought in to find out what was ailing my mother. He is first and for most experienced in many areas as my mother was diagnosed with pancreatitis. Although he transferred the surgery to another member of his team, he gave me his mobile and kept me informed of her condition/diagnosis at a time where I was unable to be with her myself because of this pandemic. His heart, compassion, understanding and bedside manner are things that I will not ever forget. He is an excellent doctor and truly a great human being.

Howard L.
