Are prior stress fractures in your shins a risk factor for peripheral arterial disease?

No. I'm not aware of any association between the two. Generally speaking, tibia stress fractures are seen in endurance athletes, while peripheral vascular disease is often seen in older, less healthy individuals, particularly smokers.
No. There should not be a correlation between stress fractures in the leg and peripheral artery disease.

Can prior stress fractures in your shins cause peripheral arterial disease?

Not Really. The injury which caused the fracture could have also injured the arteries, but a fracture alone does not cause atherosclerosis or peripheral vascular disease. If you think you have PVD symptoms, an arterial ultrasound can help rule out arterial injury.
Not likely. Peripheral arterial disease (pad) is a more generalized problem than would be caused by a localized injury like stress fractures. High blood pressure, smoking, obesity, high cholesterol, diabetes, and the like are far more likely causes for pad than stress fractures.

Is it possible that prior stress fractures in your shins are a cause of peripheral arterial disease?

Not likely. Stress fracture are independent and have no direct relationship with peripheral arterial disease (pad). Factors that increase your risk of developing peripheral artery disease include: smoking, diabetes, obesity, high blood pressure, high cholesterol, increasing age especially > 50, a family history of: pad or heart disease or stroke, excess levels of homocysteine.
No. Stress fractures are typically non-displaced. Fractures with bone displacement may cause arterial compression or injury but unusual. So stress fracture and pad are not related to each other.
