Although the clinical efficacy of hybrid procedures in patients with chronic limb ischemia has been well reported in the literature, sufficient evidence is lacking in the acute setting. Our aim was to evaluate the immediate and midterm clinical results on 28 patients with acute lower limb ischemia treated with hybrid reconstructions on emergent basis, from January 2010 to March 2013 in our tertiary referral vascular center.
Iodine contrast medium (ICM) is considered gold standard in endovascular revascularization procedures. However, nephrotoxicity and hypersensitivity to ICM are causes that limit its indiscriminate use. Carbon dioxide (CO2) contrast angiography has been used as an alternative in patients with formal contraindication to ICM. However, no studies to the present date have compared in a randomized and prospective way, outcomes of revascularization procedures performed with either ICM or CO2 in patients eligible for use of both contrasts.
In this study, we evaluated the accuracy of the indocyanine green angiography (ICGA) test to diagnose peripheral arterial disease (PAD) with isolated infrapopliteal lesions.
Iliac vein stenting has emerged as a promising new technology to address a wide spectrum of advanced chronic venous disease. Wallstent™ has been the commonest stent type used in reported experience. It has excellent long-term patency with good clinical outcome, but is prone to compression/migration of the upper end of the stent requiring reinterventions. Extension of the stent into the vena cava to avoid this problem may render subsequent contralateral stenting technically difficult and possibly contribute to partial jailing of contralateral flow. A technical modification in which a Gianturco Z stent™ is added to the upper end of the Wallstent stack that may ameliorate some of these concerns is described.
The acute thrombosis of a vascular access (TVA) is a serious complication of hemodialysis. The real incidence is not known and the management, which could influence the results, is variable according to the centers. The objective of this national survey was to evaluate the real incidence of TVA in France, and to specify the methods of their management.
The aim of this study was to evaluate the effectiveness of extensive bare stenting of the thoraco-abdominal aorta in a human ex-vivo model of type B aortic dissection, as well as the impact of this approach on the patency of the digestive and renal arteries.
To show that preoperative planning carried out on a console to rebuild iliac and superficial femoral artery (AFS) lesions decreases the rate of restenosis.
Because of its articular localization, the popliteal artery is exposed to important biomechanical constraints, inducing a specific risk of thrombosis and fracture of stents, little studied in the literature.
Transluminal angioplasties (TLA) are efficient to treat chronic critical ischemia (CCI) with lesions of the tibial arteries. The objective of our study was to evaluate the short- and mid-term results of tibial stenting and the benefit which they can bring in this indication.
Endovascular treatment now represents the first option in the management of critical ischemia of the lower extremities but the practices are not yet really standardized. The aim of our study was to evaluate the primary effectiveness and the clinical results, in the short and medium term, of the stenting of the tibial arteries.
Anterograde recanalisations of the femoro-popliteal segment and the tibial arteries have a rate of failure between 10 and 20% in spite of the technique of sub-intimal recanalisation and the use of catheters of reentry. In these cases, a retrograde approach by the popliteal artery or the tibial arteries can be a solution. Since the first description 10 years ago, the material evolved and novel methods appeared in order to optimize this approach. The aim of our study was to study the feasibility of this technique and its results in terms of patency at six months.
The patients presenting with critical ischemia of the lower extremities often have multi-segmental occlusive lesions which cannot be treated either with a bypass, because of the lack of venous material, nor with endovascular techniques because of extensive lesions and calcifications. A hybrid treatment, with a proximal femoro-popliteal bypass and a distal transluminal angioplasty (TLA) was proposed by several authors, with suboptimal results due to the degradation of the downstream network. Due to our large experience of distal and pedal bypasses, we decided to treat these patients in an opposite way: proximal angioplasty and popliteo-pedal downstream bypass, this last using a second choice venous material in the absence of an adequate greater saphenous vein (GSV).
The aim of this work was to analyze the income obtained from the management of critical ischemia and to evaluate the impact on this income of the cost of medical devices.
The realization of a distal anastomosis (DA) on massively calcified arteries (MCA) can require an endarterectomy to carry out the suture. However, it presents risks of dissection and downstream thrombosis. The objective of this study was to describe the technical sides, the indications and the results of a novel method of “open” stenting following by a thrombo-endarterectomy (OSATE) to make safe the DA in these complex cases.
To describe the use of intraprocedural motor evoked potential (MEP) monitoring to minimize risk of neural injury during percutaneous cryoablation of perineural musculoskeletal tumors.
