In a series of ≈ 10,000 patients followed after [[femoral artery catheterization]]
((Kent CK, Moscucci M, Gallagher SG, et al. Neuropathies After Cardiac Catheterization: Incidence, Clinical Patterns, and Long-Term Outcome. J Vasc Surg. 1994; 19:1008–1014))
(e.g. for coronary angiography or [[angioplasty]]), [[neuropathy]] occurred in 0.2% (with an estimated range in the [[literature]] up to ≈ 3%). Risk factors identified include patients developing [[retroperitoneal hematoma]]s or [[pseudoaneurysm]]s after the [[procedure]], procedures requiring larger introducer sheaths (e.g. angioplasty & stent placement > diagnostic catheterization), excessive [[anticoagulation]] ([[PTT]] > 90 for at least 12 hours).

[[Excruciating pain]] after the catheterization procedure often preceded the development or recognition of [[neuropathy]].
