Project description:IntroductionCommon femoral endarterectomy (CFE) has been the therapy of choice for common femoral artery atherosclerotic disease (CFA-ASD). In the past, there was inhibition to treat CFA-ASD endovascularly with stents due to fear of stent fracture and compromise of future vascular access site. However, recent advances and new evidence suggest that CFA may no longer be a 'stent-forbidden zone'. In the light of new evidence, we conducted a meta-analysis to determine the use of endovascular treatment for CFA-ASD and compare it with common femoral endarterectomy in the present era.MethodsUsing certain MeSH terms we searched multiple databases for studies done on endovascular and surgical treatment of CFA-ASD in the last two decades. Inclusion criteria were randomized control trials, observational, prospective, or retrospective studies evaluating an endovascular treatment or CFE for CFA-ASD. For comparison, studies were grouped based on the treatment strategy used for CFA-ASD: endovascular treatment with selective stenting (EVT-SS), endovascular treatment with routine stenting (EVT-RS), or common femoral endarterectomy (CFE). Primary patency (PP), target lesion revascularization (TLR), and complications were the outcomes studied. We did proportional meta-analysis using a random-effect model due to heterogeneity among the included studies. If confidence intervals of two results do not overlap, then statistical significance is determined.ResultsTwenty-eight studies met inclusion criteria (7 for EVT-RS, 8 for EVT-SS, and 13 for CFE). Total limbs involved were 2914 (306 in EVT-RS, 678 in EVT-SS, and 1930 in CFE). The pooled PP at 1 year was 84% (95% CI 75-92%) for EVT-RS, 78% (95% CI 69-85%) for EVT-SS, and 93% (95% CI 90-96%) for CFE. PP at maximum follow-up in EVT-RS was 83.7% (95% CI 74-91%) and in CFE group was 88.3% (95% CI 81-94%). The pooled target lesion revascularization (TLR) rate at one year was 8% (95% CI 4-13%) for EVT-RS, 19% (95% CI 14-23%) for EVT-SS, and 4.5% (95% CI 1-9%) for CFE. The pooled rate of local complications for EVT-RS was 5% (95% CI 2-10%), for EVT-SS was 7% (95% CI 3 to 12%), and CFE was 22% (95% CI 14-32%). Mortality at maximum follow-up in CFE group was 23.1% (95% CI 14-33%) and EVT-RS was 5.3% (95% CI 1-11%).ConclusionEVT-RS has comparable one-year PP and TLR as CFE. CFE showed an advantage over EVT-SS for one-year PP. The complication rate is lower in EVT RS and EVT SS compared to CFE. At maximum follow-up, CFE and EVT-RS have similar PP but CFE has a higher mortality. These findings support EVT-RS as a management alternative for CFA-ASD.

Project description:PurposeTo identify lesion characteristics associated with restenosis after endovascular therapy (EVT) for common femoral artery (CFA) lesions in patients with peripheral artery disease (PAD) in real-world practice.Materials and methodsWe included 751 Japanese patients with PAD who underwent CFA EVT. Data were from a large-scale retrospective multicenter registry study. The association of lesion characteristics with the risk of restenosis was investigated with the Cox proportional hazards regression model.ResultsLesions extended to the external iliac artery in 10.0% of patients, were isolated in the CFA in 59.9%, and involved the bifurcation in 30.1%. Chronic total occlusion was noted in 21.1%, and 99% stenosis, in 19.9%. Among the limbs with CFA lesions, 16.4% had a history of CFA EVT. Mean total lesion length was 32 ± 15 mm, and reference vessel diameter, 7.3 ± 1.4 mm. Plain old balloon angioplasty, drug-coated balloon angioplasty, and stent implantation were performed in 56.3, 23.2, and 20.5% of patients, respectively. The mean follow-up period was 10.4 ± 9.5 months. Rates of freedom from restenosis and reintervention at 1 year were 78.2 and 86.6%, respectively. Lesion characteristics independently associated with restenosis were history of CFA EVT, reference vessel diameter less than 6 mm, and lesion length greater than or equal to 50 mm; adjusted hazard ratios were 1.63 (P = 0.007), 1.93 (P = 0.006), and 1.71 (P = 0.018), respectively.ConclusionHistory of CFA EVT, smaller reference vessel diameter, and longer lesion length are independent risk factors for restenosis after CFA EVT.Level of evidenceLevel 3.

Project description:Endarterectomy of common femoral artery lesions (CFA) carries favorable long-term results and is currently still considered the gold standard for treating these lesions. Although routine stenting has been considered an option for treating the CFA, it has yielded conflicting results and is currently reserved for a bailout of suboptimal endovascular results. Newer therapies with atherectomy or lithoplasty in conjunction with pharmacologic anti-proliferative therapies are promising with less bailout stenting and dissections but randomized trials are needed to confirm their effectiveness and safety.

Project description:BackgroundThis study was conducted to evaluate the differences between pre- and postoperative access conditions in percutaneous endovascular aortic repair (PEVAR).MethodsBetween December 2021 and October 2023, PEVAR was performed on 61 patients using the Perclose ProStyle (Abbott Vascular). Enhanced computed tomography and ankle-brachial index tests were performed preoperatively and postoperatively. The inner diameter and area of the iliofemoral artery were automatically measured, and the pre- and postoperative values were compared (114 legs). The same analysis was performed on 12 legs with previous groin operations; open surgical EVAR was performed in 9 legs, an endarterectomy of the femoral artery in 1, and a femoropopliteal bypass in the other leg.ResultsAll patients were discharged without surgical site infections, lymphatic fistulas, or retroperitoneal haematomas. There were no significant differences between the pre-and postoperative inner diameter and inner area of the external iliac artery and common femoral artery. There were no significant differences between the preoperative and postoperative ankle-brachial index tests. In 12 legs with a previous groin operation, the postoperative ankle-brachial index tests and inner diameter and area of the external iliac artery and common femoral artery were statistically equal to the preoperative values.ConclusionsThis study can support the safety of percutaneous endovascular aortic repair, even in patients with redo groin operations.

Project description:BackgroundHighly calcific stenosis located in common femoral artery (CFA) represents a difficult target for endovascular treatment due to the possible need for stent implantation in that area.Case summaryA 63-year-old man with history of coronary artery disease and previous multiple percutaneous transluminal angioplasties for peripheral artery disease (PAD) was admitted for recent onset left lower limb pain at rest with severe activity restriction (Leriche-Fontaine Class III and Rutherford Class III-IV). The angio-computed tomography scan showed a highly calcific stenosis of left CFA. The patient underwent lithoplasty balloon angioplasty followed by drug-eluting balloon inflation with excellent angiographic result and complete blood flow restoration. No procedural complications occurred.DiscussionHighly calcified stenosis in PAD represents a huge challenge for endovascular treatment as not all lower extremity arteries are suitable for stenting because of compressive and torsional forces associated with stent fracture and restenosis. Lithoplasty is a new technology allowing effective blood flow restoration while minimizing vessel injury.

Project description:A patient with occlusion of the left superficial femoral artery (SFA) underwent endovascular intervention. Six-month follow-up angiography revealed aneurysmal dilatation of the previously stented artery. This finding may be a result of maladaptive vascular remodeling or arterial injury resulting in aneurysmal dilatation secondary to subintimal crossing, atherectomy, and paclitaxel therapies. (Level of Difficulty: Beginner.).

Project description:Background:Atherosclerotic disease of the vertebrobasilar system causes significant morbidity and mortality. All lesions require aggressive medical management, but the role of endovascular interventions remains unsettled. This study examines such endovascular interventions for vertebrobasilar atherosclerosis. Methods:Retrospective review was performed of prospectively maintained procedure logs at three hospitals with comprehensive neurointerventional services. Patients with angiographically-proven stenosis undergoing elective stent placement were selected for analysis of demographic factors, lesion characteristics, and treatment details. Multivariate analysis was performed to evaluate for associations with ischemic stroke, death, and functional status as measured by modified Rankin scale at multiple intervals. Results:One hundred and twenty-three lesions were treated in 110 patients. A total of 43 (58.1%) lesions caused stroke, while 66 (89.2%) caused transient ischemic attacks (TIAs). Forty lesions (32.5%) were at the vertebral origin; 97 (60.2%) were intracranial. A total of 112 (91.1%) were treated successfully. 4 (3.3%) of 10 (8.1%) procedural complications were symptomatic. Intracranial lesions were associated with death at 1 and 2 years (OR 24.91, P < 0.001) and mRS >2 at last contact (OR 12.83, P < 0.001). Stenting treatment with conjunctive angioplasty had lower rates of death (OR 0.303, P = 0.046) and mRS >2 at last contact (OR 0.234, P = 0.018) when angioplasty was performed with a device other than that packaged with the stent. Conclusion:Endovascular treatment of vertebrobasilar atherosclerosis can be performed safely, particularly for vertebral origin lesions. Higher rates of technical failure and complication may be acceptable for certain intracranial lesions due to their refractory nature and the morbidity caused by such lesions. Treatment should be tailored to features of each individual lesion.

Project description:Surgical endarterectomy is the preferred method for treating occlusive disease of the common femoral artery (CFA). However, endarterectomy is not always straightforward in cases with heavily calcified plaque. To overcome this limitation, a new method for decalcification, which utilizes a Cavitron ultrasonic surgical aspirator (CUSA) has been developed.The method involves full exposure of the calcified lesion. Following an arteriotomy, protruding calcification is removed using the CUSA, taking care to avoid vessel perforation. Preservation of the medial calcified layer can be accomplished by the accurate control provided by the device, which enables smooth termination in the distal area of the normal wall and does not require a tacking suture. A total of 12 patients underwent decalcification of 13 common femoral artery (CFA) lesions using CUSA with vein patch angioplasty. Concomitant profundaplasty was performed in five cases. The only intra-operative complication was perforation of the arterial wall in one patient, while another had a wound infection that required reintervention.Decalcification of a heavily calcified CFA with CUSA appears to be feasible, although long-term follow-up examinations are warranted.

Project description:Background and aimSex differences in atherosclerosis have been described with female plaques being mostly perceived as stable and fibrous. Sex-specific mechanisms such as mosaic loss of the Y chromosome in men have been linked to cardiovascular health. In women, X-linked mechanisms such as X chromosome inactivation (XCI) skewing is common in several tissues. Yet, information on the role of XCI in female atherosclerotic plaques is lacking. Here, we investigated the presence of XCI skewing in advanced atherosclerotic lesions and its association with cardiovascular risk factors, histological plaque data, and clinical data.MethodsXCI skewing was quantified in 154 atherosclerotic plaque and 55 blood DNA samples of women included in the Athero-Express study. The skewing status was determined performing the HUMARA assay. Then, we studied the relationship of XCI skewing in female plaque and cardiovascular risk factors using regression models. In addition, we studied if plaque XCI predicted plaque composition, and adverse events during 3-years follow-up using Cox proportional hazard models.ResultsXCI skewing was detected in 76 of 154 (49.4%) plaques and in 27 of 55 (67%) blood samples. None of the clinical risk factors were associated with plaque skewing. Plaque skewing was more often detected in plaques with a plaque hemorrhage (OR [95% CI]: 1.44 [1.06-1.98], P = 0.02). Moreover, skewed plaques were not associated with a higher incidence of composite and major events but were specifically associated with peripheral artery events during a 3-year follow-up period in a multivariate model (HR [95%CI]: 1.46 [1.09-1.97]; P = 0.007).ConclusionsXCI skewing is common in carotid plaques of females and is predictive for the occurrence of peripheral artery events within 3 years after carotid endarterectomy.
