Impact of Vessel Diameter Measured by Preprocedural Computed Tomography Angiography on Immediate and Late Outcomes of Endovascular Therapy for Iliac Artery Diseases

Abstract

incidence of procedural failure and periprocedural complications has been reported to be 1-5% and 4-20%, respectively, frequencies that are still clinically significant. 5- 12 We therefore investigated whether vessel diameters measured by preprocedural CTA affects the immediate (procedural failure or vessel-specific complications) and late outcomes (the need of target lesion revascularization [TLR]) of endovascular therapy for iliac artery disease. Methods SubjectsBetween 2005 and 2013, a total of 590 patients underwent endovascular therapy for symptomatic iliac artery disease. Of them, 92 with restenotic lesions, 16 with dissections, and 37 who were previously treated with stent grafts or bypass graft were excluded. Among the remaining 445 A recent meta-analysis has demonstrated that computed tomography angiography (CTA) has high diagnostic accuracy with respect to the presence and extent of peripheral artery disease (PAD). 1 CTA, with duplex ultrasound and magnetic resonance angiography, is currently recommended as a noninvasive imaging strategy for localizing lower extremity arterial disease lesions and for considering the revascularization options. 2-4 Also, preprocedural CTA can provide 3D data on the diameters of diseased segments, in addition to the degree of stenosis, whereas fluoroscopic angiography only provides 2D information on luminal narrowing. However, the prognostic value of vessel diameter measured by CTA for outcomes of endovascular therapy has not been evaluated. Although endovascular therapy has achieved high technical success rates with excellent patency for iliac artery disease and its indication has been expanded to complex lesions, 4 the Myeong-Ki Hong, MD, PhD; Yangsoo Jang, MD, PhDBackground: We evaluated whether vessel diameters measured by preprocedural computed tomography angiography (CTA) affects the immediate and late outcomes of endovascular therapy for iliac artery diseases.

Arterial diameter and the gender disparity in stroke thrombectomy outcomes

“…A study by Hong et al28 found during endovascular treatment for common and external iliac artery disease, smaller target lesion artery diameters, as determined via CTA, were independent predictors of procedural failure. Similar findings were demonstrated in patients with peripheral artery disease undergoing lower extremity bypass whereby great saphenous graft conduit diameter <3.5 mm was a primary technical determinant of graft failure 29.…”

Factors Associated with Unsuccessful Recanalization in Mechanical Thrombectomy for Acute Ischemic Stroke

“…The relationship between arterial diameter and procedural success or failure has been previously studied in extracranial vascular disease. Hong et al [23] reported that smaller diameters of the external iliac artery and the target lesion artery were independent predictors of procedural failure or vessel-specific complications in endovascular treatment of iliac artery disease. It is possible that a smaller vessel diameter is also related to procedural failure during intracranial endovascular therapy.…”

Failed recanalization mediates the association of women with poor outcomes after thrombectomy: a single-center experience

“…Similarly, the relationship between vessel diameter and procedural outcomes was reported in a study of 254 patients undergoing endovascular treatment for iliac ar-tery diseases. The investigators showed that the target vessel diameter measured using CT angiography was an independent predictor of procedural failure or vessel-specific complications [31].…”
