Case Reports
Duplication of superficial femoral artery: an uncommon variation of the lower limb arterial system.
The most common anatomical variation of the superficial femoral artery (SFA) is hypoplasia or aplasia, associated with persistent sciatic artery. Duplication of SFA remains uncommon. We report a case of SFA duplication discovered on an angiogram performed for critical limb ischemia, in an 80-year-old man.

In patients with ruptured abdominal aortic aneurysm (RAAA) and shock, the time lag between the onset of the symptoms due to RAAA and the presence of a full developed shock syndrome was evaluated to assess its prognostic meaning. This time lag was called time before shock (TBS). ⋯ TBS seems to complete the information given by the parameter "presence of shock," and its evaluation allows a more effective judgment of the risk of death, at emergency admission of patients with RAAA.
