We report our experience in stent-supported angioplasty of the left internal carotid artery in patients with anomalous origin of the left common carotid, the so-called bovine arch, in which the right brachiocephalic and left carotid share a common trunk from the aortic arch. The occurrence of the anatomic variant is discussed, and techniques of femoral, brachial, and radial approaches are described. 相似文献

Transradial vascular access for invasive procedures is gaining increasingly acceptance due to reduced access‐site complications and improved patient's comfort compared with transfemoral. However, the adoption of transradial access in peripheral vascular procedures is actually limited by anatomical and technical considerations. Yet, among all the peripheral vascular districts, the renal one seems to be particularly suitable for transradial approach. In this article, we discuss the rationale for preferring the radial approach instead of femoral and review the specific technical issues related to transradial renal artery stenting (RAS). © 2009 Wiley‐Liss, Inc. 相似文献

Background : Carotid artery stenting (CAS) has become an accepted modality of treatment for revascularization of the internal carotid artery (ICA). CAS from femoral approach has got wide acceptance, however, it can be problematic due to access site complication as well as technical difficulties related to peripheral vascular disease and/or anatomical variations of the aortic arch. Small feasibility studies of CAS through ipsilateral transradial approach have been described in the literature. The purpose of the present study is to evaluate the feasibility of contralateral transradial approach as an alternative approach for CAS. Methods : Twenty patients (mean age: 65 ± 5, 17 male) underwent CAS using contralateral transradial approach. All had a CA stenosis greater than 80%. The target common carotid artery (CCA) was initially cannulated via the contralateral radial artery using a 5F Simmons 1 diagnostic catheter or a 5F TIG diagnostic catheter, which was then advanced to the external CA (ECA) over an exchange length of 0.032″ Terumo Glidewire or a 0.025″ Glidewire. Once the catheter was parked in the optimal position in ECA, the wire was removed and was replaced by 0.035″ Amplatz Super stiff Guide wire. Following that, the Simmons 1 or the TIG catheter was removed and 6F Pinnacle Sheath was exchanged and positioned in the distal CCA. CAS was performed using standard techniques with weight‐based heparin for anticoagulation. Results : CAS was successful in 16/20 (80%) patients, including 12/12 (100%) right CA, 4/8 (50%) left CA. Mean interventional time was 40 ± 5 min. The sheath was removed immediately after the procedure. There were no radial access site complications. One patient sustained a transient ischemic attack and recovered completely with complete resolution of symptoms within 1 hr. Median Hospital stay was 3 ± 0.5 days. Angulation of left CCA with the aortic arch was the technical cause of failure in the four unsuccessful cases. Conclusion : CAS using the contralateral transradial approach appears to be safe and technically feasible. The technique may be particularly useful in patients with right ICA lesions because of the favorable right CCA angle with the aortic arch. © 2009 Wiley‐Liss, Inc. 相似文献

Carotid artery stenting (CAS) is a valid and effective alternative to endoatherectomy when performed by experienced operators. The conventional approach used is the transfemoral one, but in the last 10 years a transradial (TR) approach, the standard access for cardiac catheterization, became widely adopted for peripheral vascular interventions, included the extracranial carotids. Preliminary experiences suggest this approach as safe and effective, especially in specific anatomical and clinical settings that have been shown to be associated with high risk of complications from the femoral route. Lacking international guidelines, this document, promoted by the Italian Society of Interventional Cardiology - Gruppo Italiano Studi Emodinamici (SICI-GISE), was drawn-up by a panel of interventional cardiologists with a documented experience on the subject, focusing on the indications, techniques and materials that should be used for this type of intervention and the most recent literature on the subject. 相似文献

Pseudoaneurysm formation is a life‐threatening complication of thoracic aortic stenting due to the high risk of rupture. When located in the aortic arch, anatomic features may pose difficulties in choosing the optimal treatment strategy. Here, we describe the first poststenting aortic arch pseudoaneurysm treated by endovascular coil embolization. This approach, which we performed in a multidisciplinary setting, may be a feasible alternative in patients not considered suitable for open repair or stent‐grafting. As an acute pseudoaneurysm may develop and rapidly expand during the first days after aortic stenting, early follow‐up imaging is preferable. 相似文献

Chronic mesenteric ischemia (CMI) occurs in the presence of slowly progressive, long-standing stenoses of the visceral arteries secondary to atherosclerosis. Angioplasty and stenting are emerging as therapeutic alternatives to surgery in treating CMI. The transradial approach is an attractive alternative access for performing stenting in CMI at improved safety and ease. A case of CMI treated with stenting of the visceral arteries by both transradial and femoral approaches is presented here. The main difficulty in accessing the celiac and mesenteric arteries through the femoral approach is the angle between the aorta and these vessels, which often leads the operator to use multiple catheters. The main advantage of the radial approach (as well as the brachial one) is that it allows easy coaxial alignment of the catheter with the artery. The main problem is the inadequate length of the currently available catheters. The radial approach eliminates the risk for vascular complications and permits early ambulation. 相似文献

Neurological complications of coarctation of aorta include spontaneous SAH, intracerebral hemorrhage, and cerebral abscess. Interrupted aortic arch (IAA) present as compressive myelopathy is not known. We describe an adult male presenting to neurology department with progressive paraparesis and was detected to have IAA with intraspinal collaterals causing compressive myelopathy. He was successfully treated with percutaneous stenting of IAA with dramatic improvement in paraparesis. © 2014 Wiley Periodicals, Inc. 相似文献

BACKGROUND: Carotid artery stenting (CAS) has become accepted as an alternative to carotid endarterectomy for revascularization of the internal carotid artery (ICA) among high risk patients. CAS from the femoral approach can be problematic due to access site complications as well as technical difficulties related to peripheral vascular disease (PVD) and/or anatomical variations of the aortic arch. The purpose of the present study is to evaluate the feasibility of the radial artery as an alternative approach for CAS. METHODS: Forty-two patients (mean age 71 +/- 1, 26 male) underwent CAS. All had a CA stenosis greater than 80% and comorbid conditions increasing the risk of carotid endarterectomy. The target common carotid artery (CCA) was initially cannulated via the radial artery using a 5F Simmons 1 diagnostic catheter which was then advanced to the external CA (ECA) over an extra support 0.014" coronary guidewire. After removing the coronary guidewire, a 0.035" guidewire was advanced into the ECA, and the Simmons 1 was exchanged for a 5F or 6F shuttle sheath and positioned in the distal CCA. In four patients with a bovine aortic arch, the left CCA was accessed with a 5F Amplatz R2 catheter which was then exchanged for a shuttle sheath over a 0.035" guidewire. CAS was performed using standard techniques with weight-based bivalirudin for anticoagulation. RESULTS: CAS was successful in 35/42 (83%) patients, including 28/29 (97%) right CA, 4/5 (80%) bovine left CA, 7/13 (54%) left CA. Mean interventional time was 30 +/- 3 minutes. The sheath was removed immediately after the procedure. There were no radial access site complications. One patient sustained a stroke 24 hrs after the procedure with complete resolution of symptoms (Mean NIH stroke scale 2.0 +/- 0.3 before, 1.9 +/- 0.3 after). Median hospital stay was 2 +/- 0.6 days. Inadequate catheter support at the origin of the CCA was the technical cause of failure in the seven unsuccessful cases. CONCLUSION: CAS using the transradial approach appears to be safe and technically feasible. The technique may be particularly useful in patients with right ICA lesions and severe PVD or unfavorable arch anatomy, and among patients with a bovine aortic arch. 相似文献

Although sporadic successful cases using the transradial approach (TRA) for carotid stenting have been reported, the safety and feasibility of carotid stenting using either TRA or a transbrachial approach (TBA) have not been fully investigated. Recently, we have developed a safe and feasible method of TRA for cerebrovascular angiographic studies. This study investigated whether a TBA approach using a 7-French (F) Kimny guiding catheter for carotid stenting is safe and feasible for patients with severe carotid stenosis. Thirteen patients were enrolled into this study (age range, 63-78 years). Seven of these 13 patients had severe peripheral vascular disease. A retrograde-engagement technique, involving looping 6-F Kimny guiding catheter, was utilized for carotid angiographic study. For carotid stenting, the 6-F Kimny guiding catheter was replaced with a 7-F Kimny guiding catheter, and the procedure was performed as the follows. First, an extra-support wire was inserted into the middle portion of external carotid artery (ECA). Second, a 0.035-inch Teflon wire was advanced into the common carotid artery. Then, the 6-F guiding catheter was exchanged for a 7-F Kimny guiding catheter. Third, if the first and second steps did not provide adequate support for exchanging the guiding catheter, a PercuSurge GuardWire was inserted into the ECA, followed by distal balloon inflation for an anchoring support. FilterWire EX was used in 9 patients and PercuSurge GuardWire in 4 patients to protect from distal embolization during the procedure. The procedure was successful in all patients. No neurological or vascular bleeding complications were observed and all patients were discharged uneventfully. The TBA for carotid stenting was safe and effective, providing a last resort for patients unsuited to femoral arterial access and surgical intervention. 相似文献

Background : Little is known on the performance of newly initiated carotid artery stenting (CAS) programs. The safety of the procedure is being questioned following the publication of the EVA‐3S trial, a study criticized for the limited interventional experience required to enroll patients. Methods : Within a newly started academic CAS program, patient data and outcomes were collected prospectively. The outcomes of the first 100 consecutive patients treated are reported. A CAS‐fellowship‐trained interventionalist was involved in all procedures. All patients underwent clinical assessment by a neurologist before and after the procedure, and serial ECG and cardiac enzymes were routinely obtained. Primary outcome measures included 30‐day major adverse events (MAE), defined as death, stroke, or myocardial infarction, while on follow‐up deaths and ipsilateral strokes were added. Results : Between July 2003 and November 2006, 92 patients had a single internal carotid artery treated, while 7 underwent staged bilateral CAS. In one patient, the procedure was aborted prior to lesion treatment. The 30‐day MAE rate per procedure was 1.9% (one major and one minor stroke). By a mean follow‐up of 16 months (range 2–42 months), one patient had died of refractory heart failure, while one patient had a minor ipsilateral stroke and three had minor contralateral strokes, corresponding to total MAE per patient of 4%. The rate of any stroke or death was 7%. The rate of restenosis ≥50% per lesion by ultrasound was 3.8%. Conclusion : This single center experience suggests that it is safe to start a CAS program following dedicated fellowship. © 2008 Wiley‐Liss, Inc. 相似文献

Several types of brain injury incurred during carotid artery stenting (CAS), such as embolic injury, hemodynamic events, and hemorrhage. Rapid differential diagnosis is important for decision making, and may help to avoid subsequent complications. Here, we describe a case with severe triple vessel coronary artery disease, who underwent right coronary artery (RCA) stenting and ad hoc left CAS. Patient developed neurological deficit two hours after the procedure. Brain computed tomography (CT) revealed diffuse cortical enhancement similar to subarachnoid hemorrhage (SAH). Patient recovered dramatically with complete resolution of contrast enhancement after four days of conservative treatment, final diagnosis was a rare reported case of transient contrast encephalopathy. © 2008 Wiley‐Liss, Inc. 相似文献

Background : Treatment of angiographic string sign (SS) of the carotid artery with carotid endarterectomy or carotid artery stenting (CAS) has been associated with a high incidence of periprocedural neurological events. We describe our experience with CAS in a case series of symptomatic patients with severe carotid stenosis and angiographic SS. Methods : We performed a retrospective review from 1999 to 2009 using our cardiac cath laboratory database and identified nine patients with the angiographic SS who underwent CAS. All patients were referred for carotid angiography by a neurologist due to symptoms (stroke or transient ischemic attack (TIA)). All lesions were predilated and treated with self‐expanding stents. Distal protection devices were utilized (six patients) once they became available. Periprocedural outcomes and long‐term follow‐up was reviewed when available. Results : The average time from onset of symptoms to CAS was 45 days. All CAS procedures were technically and clinically successful without acute complications. One year follow‐up was available in eight patients. One patient had a possible TIA, and the remaining seven patients did not report any events (death, stroke, TIA or myocardial infarction). Carotid ultrasound evaluation at 12 months was available in six patients and showed no evidence of restenosis. Conclusions : In our experience, CAS in patients with severe symptomatic carotid stenosis and angiographic SS is feasible, with an acceptably low periprocedural complication rate. © 2010 Wiley‐Liss, Inc. 相似文献

Carotid artery stenting (CAS) has increased in popularity as an alternative to carotid artery endarterectomy for the treatment of significant carotid artery stenosis. The access site is predominantly the femoral artery, with radial or brachial access used less often. Here, we describe a case of CAS after failure of brachial access. Transulnar CAS was performed successfully without complications. Transulnar access represents an additional option in a patient undergoing CAS when conventional femoral, brachial, and radial arteries are not applicable. © 2012 Wiley Periodicals, Inc. 相似文献

A 61-year-old man underwent carotid stenting with the distal-balloon protection system for symptomatic carotid artery stenosis. During the procedure, progressive elevation of the systolic blood pressure occurred, reaching a peak of 220 mm Hg immediately following deflation of the distal balloon. This was associated with severe headaches and progressive deterioration in the mental status to a coma. Head CT scan showed massive subarachnoidal hemorrhage contralateral to the stented side and a secondary intracerebral hemorrhage. Despite immediate successful blood pressure control, his condition deteriorated and he died 2 days later. 相似文献

The treatment of carotid disease continues to evolve with an increasing number of the lesions being successfully treated percutaneously. A large part of the success of percutaneous therapy has resulted from the use of distal protection devices and their ability to reduce embolization and subsequent strokes. However, device retrieval through implanted stents can be problematic. We describe situations in which difficulty was encountered advancing the distal protection filter retrieval device through the stent, as well as the different approaches to solve this potential problem. 相似文献
