ABSTRACT
Objective To evaluate the feasibility and safety of simultaneous carotid endarterectomy (CEA) and carotid stenting (CAS) for bilateral carotid stenosis.Methods From Jan 2012 to Aug 2014,8 patients underwent simultaneous CEA and CAS.The surgical plan was based on clinical features and imaging findings.CEA before CAS was done in 5 patients,CAS before CEA was done in 3 patients.One patient also underwent simultaneous coronary artery bypass grafting due to unstable angina.Results Operation success rate was 100％.Intraoperative carotid shunts,patches and embolic protection devices were used in all patients.One patient developed post-procedural hyperperfusion syndrome and returned to normal after symptomatic treatment.The remaining patients recovered uneventfully,there were no cerebrovascular accident,nerve injury or wound complications.Follow-up period was 18-48 months,follow-up rate was 100％.During the follow-up,all patients were relatively stable,no re-stenosis,death or cardiovascular events.Conclusions Through thorough evaluation,careful preparation,and strict management,simultaneous CEA and CAS is a technically feasible and safe treatment strategy for bilateral carotid stenosis.
ABSTRACT
Objective To compare the outcome and early patency rate of revascularization treatment for patients with iliac artery occlusion or stenosis.Methods Retrospective analysis was made on 105 cases of iliac artery occlusion or stenosis from January 2009 to April 2014.49 were with iliac artery occlusion and 56 with iliac artery stenosis.Results The demographics,and comorbidities were not statistically different between the 2 groups.The occlusion group had more critical limb ischemia and the ankle-brachial index was lower than the stenosis group.The occlusion group underwent more hybrid surgery and used more covered stents in the operation.The peri-operative complication was higher in the occlusion group,but the difference was not statistically different.The ABI improved significantly for all patients after surgery.The early patency rate was similar in the 2 groups.Conclusions Revascularization treatment for patients with iliac artery occlusion and stenosis was safe and effective,with similar early patency rate and peri-operative complications between the two groups.
ABSTRACT
Objective To evaluate carotid endarterectomy (CEA) for bilateral moderate to severe carotid stenosis.Methods The clinical data of 59 patients with bilateral moderate to severe carotid stenosis who were treated with CEA in our hospital from October 2010 to August 2014 were retrospectively analyzed.There were 50 males and 9 females age ranging 42-80 years (mean:65 ± 9 years).48 patientsunderwent ipsilateral CEA and 11 underwent staged bilateral CEA.In patients who were confirmed to have coronary artery disease or peripheral vascular disease by preoperative angiography,6 received coronary artery bypass graft (CABG)simultaneously,1 received iliac artery balloon angioplasty and stent implantation simultaneously,and 1 received renal artery stenting simultaneously.Results A total of 70 endarterectomies were performed,shunt and patching were used in all patients,the surgical success rate was 100％.2 patients suffered from vagus nerve injury,4 patients suffered from hypoglossal nerve injury,and 3 patients presented with hyperperfusion syndrome.Follow-up period was 2-36 months (mean:19 ± 10 months).1 patient died of heart attack during the follow-up,the other patients were relatively stable with no restenosis.Conclusion CEA should be performed in patients with bilateral moderate to severe carotid stenosis,and the prognosis is good.
ABSTRACT
The clinical data of 21 patients with carotid body tumor (CBT) were analyzed retrospectively.The lesions were unilateral (n =20) and bilateral (n =1).Among 20 surgical cases, the procedures included tumor resection alone (n =11) , tumor resection along with external carotid artery (n =6) and vascular reconstruction of carotid artery after resection of tumor body (n =3).No mortality occurred during perioperative period.CBT was confirmed by pathologic examination in all cases and 1 case was malignant.Follow-up period ranged from 3 months to 7 years and the follow-up rate was 85％.Five cases of cranial nerve impairment recovered completely over 3 months.One case of bilateral CBT underwent contralateral tumor resection at another hospital 1 year later and 1 case with malignant tumor died from metastases 3 years later.The remainder survived recurrence-free.CBT tends to be misdiagnosed.Therefore ultrasonography, digital subtraction angiography (DSA), CT angiography (CTA) or magnetic resonance angiography (MRA) are important for preoperative diagnosis and evaluation.Surgical resection is a first choice for CBT.
