It usually involves removal of thrombi (blood clots), and is then referred to as thromboembolectomy or thrombectomy. Embolectomy is an emergency procedure often as the last resort because permanent occlusion of a significant blood flow to an organ leads to necrosis. Other involved therapeutic options are anticoagulation and thrombolysis.
It is commonly performed in the cerebral arteries (interventional neuroradiology) as treatment to reverse the ischemia in some ischemic strokes (i.e., those in which the blockage is a suitable candidate for such retrieval). Open vascular surgery versions of thrombectomy also exist. The effectiveness of thrombectomy for strokes was confirmed in ...
Treatment for PCD includes immediate anticoagulation, fluid resuscitation, bed rest, limb elevation above 60º, limb wrap to reduce pain and edema, and either catheter-based thrombolysis, percutaneous transluminal angioplasty, or surgical venous thrombectomy +/- fasciotomy to remove the blood clot.
Thrombolysis is the injection of an enzyme into the veins to dissolve blood clots, and while this treatment has been proven effective against the life-threatening emergency clots of stroke and heart attacks, randomized controlled trials [139] [140] [141] have not established a net benefit in those with acute proximal DVT.
The treatments to prevent the formation of blood clots is balanced against the risk of bleeding. [5] One of the goals of blood clot prevention is to limit venous stasis as this is a significant risk factor for forming blood clots in the deep veins of the legs. [6] Venous stasis can occur during the long periods of not moving.
Acute limb ischemia may also be caused by traumatic disruption of blood flow to a limb, which may present with either hard signs or soft signs of vascular injury. [15] Hard signs include pulsatile bleeding, expanding hematomas (collections of blood), or absent distal pulses, and must be taken to surgery emergently.
