Pressure ulcers can trigger other ailments, cause considerable suffering, and can be expensive to treat. Some complications include autonomic dysreflexia, bladder distension, bone infection, pyarthrosis, sepsis, amyloidosis, anemia, urethral fistula, gangrene and very rarely malignant transformation (Marjolin's ulcer – secondary carcinomas in chronic wounds).
Foot of an 80-year old individual with type 2 diabetes and heart failure. The second toe has a large ischaemic ulcer. The first toe has a small one. The prevalence of arterial insufficiency ulcers among people with Diabetes is high due to decreased blood flow caused by the thinning of arteries and the lack of sensation due to diabetic neuropathy.
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).
Repeated bouts of ischemia and reperfusion injury also are thought to be a factor leading to the formation and failure to heal of chronic wounds such as pressure sores and diabetic foot ulcer. [4] Continuous pressure limits blood supply and causes ischemia, and the inflammation occurs during reperfusion.
Venous ulcers are costly to treat, and there is a significant chance that they will recur after healing; [3] [10] one study found that up to 48% of venous ulcers had recurred by the fifth year after healing. [10] However treatment with local anaesthetic endovenous techniques suggests a reduction of this high recurrence rate is possible. [48]
Negative pressure wound therapy (NPWT) is a treatment that improves ischemic tissues and removes wound fluid used by bacteria. [8] [14] This therapy, also known as vacuum-assisted closure, reduces swelling in tissues, which brings more blood and nutrients to the area, as does the negative pressure itself. [8]
Treatment of SRUS is difficult and there is a lack of evidence-based guidelines. [4] The treatment is based on the pathophysiology of SRUS, [5] and the main aim is restoration of a normal pattern of defecation. [1] The exact treatment depends on the severity of the symptoms, the severity/type of SRUS, and whether rectal prolapse is present or ...
A Cushing ulcer, named after Harvey Cushing, [1] [2] is a gastric ulcer associated with elevated intracranial pressure. It is also called von Rokitansky –Cushing syndrome. [ 2 ] Apart from the stomach , ulcers may also develop in the proximal duodenum and distal esophagus .
