What finding indicates a complication after a renal angiography via the right femoral artery?

A finding indicating a complication after a renal angiography via the right femoral artery would be pallor and coolness of the right leg. This symptom suggests that there may be compromised blood flow to the limb, potentially due to complications such as arterial occlusion or hematoma formation at the access site. Following a procedure that involves catheterization of a major artery, it is crucial to monitor for signs of inadequate perfusion to the affected leg, as this can lead to serious ischemia if not addressed promptly.

Increased heart rate can be a nonspecific response to pain or anxiety, but it does not directly correlate with a vascular complication specific to the angiography procedure. Gastrointestinal discomfort could arise from various factors unrelated to the intervention itself, such as reactions to contrast media used during the angiography, but it is not typically indicative of vascular complications. Elevated blood pressure may occur post-procedure due to various reasons, including stress or pain, and does not specifically point to an issue related to the femoral artery access site or leg perfusion. Thus, the presence of pallor and coolness is a clear indicator of a potential and serious complication that warrants immediate medical assessment.
