“…Factors previously shown to contribute to ISR include age, diabetes mellitus, smoking, hyperlipidemia, small diameter stent (≤4 mm), longer stent length, tortuous V1 segment, long stenosis (>10 mm), contralateral VA hypoplasia, and contralateral VA occlusion at the time of stenting [ 17 , 25 – 34 ]. The VAO has a high elastin concentration, which may increase the risk of stent recoil, kinking, and deformation, and contribute to ISR [ 35 , 36 ].…”

Background and Purpose. The cause of in-stent restenosis (ISR) after vertebral artery ostium (VAO) stenting remains unclear. We evaluated factors associated with ISR in patients who underwent VAO stenting. We also assessed the feasibility of stenting for treating VAO stenosis (VAOS). Methods. Between January 2016 and October 2018, sixty-four consecutive patients who underwent a total of 66 stenting procedures were screened for symptomatic and asymptomatic atherosclerotic VAOS. Of these patients, 57 had complete follow-up data. The baseline patient demographics and morphological features of the VAO were recorded. Potential factors influencing ISR, including conventional cerebrovascular disease risk factors, were assessed, together with outcome events including recurrent transient ischemic attack (TIA), stroke, and vascular-related mortality. Results. The average follow-up period was 13.2 ± 4.6 months. Technical success was achieved in all interventions. The degree of stenosis was reduced from 77.2 ± 6.1 % to 13.7 ± 8.9 % after the procedure. ISR was detected in eight treated vessels (14.0%) and occlusion in two (5.3%) arteries. Of the 57 patients, one had an ischemic stroke and 5 had TIAs. The angle of the VAO at the subclavian artery was associated with the risk of restenosis (preoperative, P = 0.04 ; postoperative, P = 0.02 ). Conclusions. Stenting is a feasible and effective treatment for VAOS. The angle of the VAO at the subclavian artery may contribute to the development of ISR.

“…Although VA ostium stenting is considered to be a safe treatment option, high rates of restenosis and delayed stent fractures remained [32] , [33] , [34] , [35] , [36] . Using of drug eluting stents decrease neointimal hyperplasia related in-stent restenosis in VA.…”

The coexistence of severe extracranial large vessel stenosis and unruptured intracranial aneurysms is not rare. There are different treatment approaches for these conditions, such as initial treatment of the aneurysm before revascularization of the stenosis; single-stage endovascular treatment of both lesions; stenosis eliminating followed by treatment of the aneurysm, or without treating the aneurysm. But, taking into account the risk of aneurysm rupture on the one hand and the risk of ischemic stroke on the other, it is sometimes difficult to choose the right management strategy. Despite this fact, there are still no guidelines or consensus on the management of these coexistent lesions. The article describes a clinical case of endovascular treatment of multiple extracranial stenosis and coexistent unruptured wide-neck aneurysm of the middle cerebral artery. The endovascular treatment of the carotid stenosis and aneurysm using a woven endobridge device was performed in one session; endovascular treatment of vertebral artery stenosis with Szabo technique was performed in another session.

“…Balloon-expandable stents are commonly used as the treatment modality for symptomatic artery stenosis [2][3][4]. Self-expanding stents have enhanced radial expanding force, which are higher resistive force and greater flexibility compared to balloon-expandable [20]. Although both stents have excellent long-term patency with good clinical outcomes, occlusion and/or stent compression of balloon-expandable stents are more probable during endovascular treatment of the iliac arteries [2][3][4].…”

Extrinsic compression of iliac arteries stents has been reported from different causes, such as uterine fibroids and orthopedic surgery. Although extrinsic compression of stents in the iliac veins has been widely studied, stent compression in the iliac arteries is less common. Here we presented a case with bilateral common iliac arteries stent compression following pelvic surgery. A patient (65-year-old woman) presented with acute critical right limb ischemia. Computed tomography angiography (CTA) showed occlusion of the right common and external iliac artery, and severe stenosis in the left common iliac artery. In addition, there was evidence of a Brenner tumor originating from the left ovary. The patient underwent endovascular recanalization of the right iliac arteries and bilateral balloon-expandable stent deployment, and the ovarian tumor was removed after three weeks. The control CTA scan showed asymmetric bilateral iliac arteries stent compression more prominent on the right side, then self-expanding stents were implanted bilaterally. In Conclusion although iatrogenic compression of the stent in the iliac artery is rare despite scarcity, it is important to maintain a high index of suspicion in selected cases and choose the proper stent accordingly.
