hypoperfusion syndrome

hypoperfusion syndrome

A 'prerenal' circulatory disorder 2º to
1. Occlusive renal arterial disease with stenosis and ischemia, resulting in ↑ renin, HTN and azotemia, affecting one or both kidneys,.
2. ↓ Effective circulatory volume, due to ↑ vascular capacitance–eg, induced by sepsis, sequestration of fluids in compartments–eg, in the hepatorenal syndrome or ascites, or the inability to effectively transfer fluids from the venous compartment to the arterial compartment due to CHF or pericardial limitations due to constrictive pericarditis or effusions; the ↓ volume form of hypoperfusion is associated with oliguria, azotemia, ↓ sodium excretion and ↑ renin, but not HTN.

The digital hypoperfusion syndrome is a result of the arterial theft and can evolve progressively over a long period of time with paresthesia, pain and pale discoloration of the skin when exposed to cold.
However, only 8% of these patients developed a symptomatic hypoperfusion syndrome [3].
The results of his study show that such a technique is successful in preventing the digital hypoperfusion syndrome and venous hypertension despite the fact that in his study 22% of the patients were diabetic patients [4].
