The first line approach for subclavian steal syndrome is PTA-stenting of subclavian artery. When the ipsilateral vertebral artery origin is involved or in closed proximity of the atherosclerotic lesion in the subclavian artery PTA-stenting is at risk of ipsilateral vertebral artery coverage. Herein we report our experience with DEB to address lesions involving the subclavian artery and the origin of the ipsilateral vertebral artery. From January 2017 to February 2019, patients presenting subclavian artery lesion involving the origin of the ipsilateral vertebral artery and treated using primary DEB, were included. Three patients, with left subclavian steal syndrome, were identified. The perioperative mortality and morbidity were outcomes evaluated. Freedom from occlusion, secondary patency, amputation rate was registered. A total of 3 (2 female) patients were included in the study. No complication, symptoms recurrence, restenosis or occlusion were reported at duplex scan during 12-month follow-up. Indication for stenting was arterial dissection. In our limited experience, the use of DEB in association to embolic protection device in the treatment of atherosclerotic subclavian lesion involving the origin of the vertebral artery was safe and technically feasible.

We report on a case of an asymptomatic splenic artery aneurysm (SAA) with a large neck in a 53-year-old female with an extreme vessel tortuosity which was treated with a Double Microcatheter Technique. This endovascular procedure consists of embolization of the aneurysm using detachable coils with no application of any glue, stent or balloon. At the end of procedure, no complications occurred. At the three-month follow-up an MRI showed the aneurysm's complete exclusion and patency of the splenic artery.

Non-atheromatous surgical lesions are estimated to represent at most 10% of all carotid procedures, most of which involve atheromatous lesions. Isolated tortuosity of the carotid vessels is sometimes treated surgically. The pathologies most frequently studied are extra-cranial carotid aneurysms, dissections, and fibromuscular dysplasia. Behcet's disease only rarely affects the carotid trunk, but in view of its prevalence in our country of Algeria a short section will be devoted to it. A series of 57 patients treated for non-atheromatous carotid lesions is presented article. These cases were treated using both endovascular and conventional surgical techniques. A review of the literature shows that endovascular treatment is now replacing conventional surgery for most indications except carotid paraganglioma.

Notwithstanding technological improvements in endovascular devices treatment of steno-obstructive lesions of the superficial femoral artery (SFA) remains a challenge for today's vascular surgeon. Current opinion dictates that the diabetic population may have worse outcome after revascularization of the lower extremities. Herein we examine the effects of endovascular treatment on steno-obstructive lesions of the SFA in diabetic and non-diabetic patients.

Methods: A retrospective analysis was carried out on 110 patients who had undergone endovascular treatment of the SFA from 2010 to 2017 comparing outcomes in diabetic (DM) vs non-diabetic patients (nDM).

Results: 56 (50.9%) of the patients were diabetic and 54 were non-diabetic (49.1%). 52.7% (62.7% DM vs 35.2% nDM, p = 0.0003) were patients with critical limb ischemia. SFA occlusion was present in 65.5% (60.7% DM vs 70.4% nDM, p = 0.29) of all patients. All had undergone PTA of the SFA and 40.9% had received adjunctive stenting (44.6% DM vs 37.0% nDM, p = 0.41). A multilevel treatment was executed in 39.1% (51.8% DM vs 25.9% nDM) of the cases whereas an infra-popliteal procedure was associated in 27.3% (37.5% DM vs 16.7% nDM). In both groups the presence of diabetes was significantly associated (p = 0.005 e p = 0.014, respectively). Reintervention rate was 22.7%; 13 in the diabetic group (23.2%) and 12 in the non-diabetic group (22.2%). Of those who had had reintervention (p = 0.77); 9 patients (8.2%) had undergone an open surgical operation, 6 of whom had diabetes (p = 0.32). 5 patients (4.5%) had had major amputation, 4 of whom were diabetic (p = 0.20). Curves assessing freedom from target lesion restenosis were substantially overlapping between the two groups.

Conclusion: No statistical associations between diabetes and reintervention or amputation rates were found. Indication to treat the SFA were not influenced by the presence of diabetes but further investigation is required to verify our hypothesis.
