Carotid endarterectomy is used to reduce the risk of strokes caused by carotid artery stenosis over time. Carotid stenosis can either have symptoms (i.e., be symptomatic), or be found by a doctor in the absence of symptoms (asymptomatic) - and the risk-reduction from endarterectomy is greater for symptomatic than asymptomatic patients.
Where there is extensive vascular damage, bypass surgery of the vessels may be necessary to establish other ways to supply the affected parts. [8] Swelling of the limb may cause inhibited flow by increased pressure, and in the legs (but very rarely in the arms), this may indicate a fasciotomy, opening up all four leg compartments. [8]
Critical limb ischemia is diagnosed by the presence of ischemic rest pain, and an ulcers that will not heal or gangrene due to insufficient blood flow. [3] Insufficient blood flow may be confirmed by ankle-brachial index (ABI), ankle pressure, toe-brachial index (TBI), toe systolic pressure, transcutaneous oxygen measurement (TcpO2 ), or skin perfusion pressure (SPP).
Spinal cord stroke is a rare type of stroke with compromised blood flow to any region of spinal cord owing to occlusion or bleeding, leading to irreversible neuronal death. [1] It can be classified into two types, ischaemia and haemorrhage, in which the former accounts for 86% of all cases, a pattern similar to cerebral stroke.
Surgery is often recommended in those with Rutherford Class 2b or greater, as blood flow is generally restored much more quickly. The primary surgical intervention in acute limb ischaemia is emergency embolectomy using a Fogarty Catheter , providing the limb is still viable within the 4-6h timeframe. [ 25 ]
Symptoms of LSS, including NC, are the most common reason patients 65 and older undergo spinal surgery. Surgery is generally reserved for patients whose symptoms do not improve with nonsurgical treatments, and the main objective of surgery is to relieve pressure on the spinal nerve roots and recover normal mobility and quality of life.

The use of lower leg compression stockings has been found to reduce symptoms and heart rate when standing upright, in patients with postural orthostatic tachycardia syndrome. Usage of compression garments on abdomen and thighs, and a combination of abdominal/thigh and leg covering compression was found to be more effective, with the latter ...
With PTS, these symptoms typically are worse after walking or standing for long periods of time and improve with resting or elevating the leg. [1] PTS lowers a person's quality of life after DVT, specifically with regards to physical and psychological symptoms and limitations in daily activities. [2] [3] [4]
