Acute Arterial Insufficiency

Interruption of the arterial blood supply and the oxygen it delivers, to an extremity, may occur as a result of trauma, during a surgery, as a result of frostbite or as a result of a blood clot.

Blood flow must be re-established for limb preservation; however, this sets into motion a chain of physiological events called ”reperfusion injury”, which drastically effects the blood vessels themselves. When this occurs, the injured blood vessel may quickly re-clot or narrow due to injury to its lining resulting in another episode of failure of blood and oxygen delivery to the tissues.

The end result is injury and possibly death of involved skin, muscle, nerve and bone with loss of a portion of the extremity. The high blood levels of oxygen achieved by Hyperbaric Oxygen Therapy (HBO), can deliver sufficient oxygen to aid blood vessels in recovering their normal function.

Hyperbaric Oxygen Therapy for Acute Arterial Insufficiency

Because reperfusion injury develops quickly the addition of Hyperbaric Oxygen Therapy (HBO), as an adjunctive therapy to surgically or chemically restoring arterial blood flow should be considered as soon as possible when arterial blood flow has been compromised by a blood clot, frostbite, crush injury or arterial injury. At the Hyperbaric Medicine Center we work with a team of Vascular Surgeons and Interventional Radiologists with experience in restoring arterial blood flow.
