Abstract
Background:
Carotid endarterectomy (CEA) with patch angioplasty has been favored due to its lower reoccurrence of restenosis compared to primary CEA. There are multiple types of patch angioplasty material available. However, selection of patch material is based on uncertain criteria. The aim of this study is to determine the ideal criteria for selecting the best patch material for CEA.
Methods:
We conducted a comprehensive literature search for studies that describe the ideal criteria for selecting patch material for CEA. We compiled all of the criteria mentioned into one table and selecting the criteria which were most frequently mentioned with a simple scoring system.
Results:
A total of 65 studies out of 784 studies were assessed for its full-text eligibility. Thus, we found 23 studies that were eligible for analysis. There are 22 ideal criteria that were mentioned in the analyzed studies. We grouped these criteria into physical characteristics, safety, contribution to hemodynamic, contribution in tissue healing, economic aspect, and ability to prevent postsurgical complication. We proposed 10 ideal criteria for guiding vascular surgeon in selecting the best patch angioplasty material.
Conclusion:
To this day, no material has been discovered which meets all ten criteria. This study’s proposed ideal criteria serve as the foundation for the creation of the best patch angioplasty material.

Abstract
Abstract
OBJECTIVE
Carotid endarterectomy with a patch graft (Patch CEA) has been our standard treatment for patients with carotid artery stenosis, but carotid artery stenting (CAS) has emerged as an alternative. The purpose of this study was to compare the postoperative changes in the configurations and the flow velocities of carotid arteries after CAS or Patch CEA.
METHODS
Thirty-one patients undergoing CAS or Patch CEA were included. The pre- and postoperative shapes of the carotid arteries were evaluated by angiography and ultrasonography. Doppler waveforms were recorded in the middle portion of the common carotid artery and in the internal carotid artery bulb to measure flow velocities, including peak systolic, mean, and end-diastolic velocities.
RESULTS
Eighteen patients were treated by CAS, and Patch CEA was performed for 13 patients. Preoperatively, there were no differences in the degrees of stenosis or the flow velocities between the 2 groups. The averages of the diameters of the postoperative internal carotid artery bulbs were 4.5 mm in the CAS group and 7.0 mm in the Patch CEA group (P < 0.01). The averages of peak systolic, mean, and end-diastolic velocities measured in the internal carotid artery were 80, 42, and 25 cm/s, respectively, in the CAS group, and were significantly greater than those (53, 28, and 16 cm/s, respectively) in the Patch CEA group (P < 0.01).
CONCLUSION
Significant differences in postoperative morphological and hemodynamic conditions between CAS and Patch CEA were observed. The impact of these differences will be determined by further studies.

Abstract
Background and Purpose—
We sought to determine the incidence of recurrent stenosis after carotid endarterectomy.
Methods—
One thousand consecutive carotid endarterectomy patients were followed prospectively. The surgery was performed in a standard fashion. Cerebral protection was provided with intraoperative electroencephalographic monitoring and selective shunting. All arteriotomies were repaired with a patch graft. Each patient was seen 3 months after surgery and then yearly, with a duplex ultrasound obtained at each visit. Evidence for new ischemic events or recurrent stenosis of ≥70% was recorded.
Results—
The 30-day combined minor and major stroke and death rate was 1.9%. At 7.1-year follow-up, 0.1% of patients had recurrent stenosis ≥70%, the majority of which were asymptomatic.
Conclusions—
Carotid endarterectomy is a low-risk procedure for the treatment of carotid occlusive disease, with excellent long-term durability. Although less invasive, carotid angioplasty must demonstrate equal robustness in long-term follow-up before it is considered a routine alternative to surgery.

Abstract
OBJECT Many surgeons inject a local anesthetic agent into the carotid sinus before carotid endarterectomy in an attempt to ameliorate perioperative hemodynamic instability. The purpose of this study is to analyze the effect of carotid sinus injection with lidocaine on perioperative hemodynamics and complications. METHODS The authors prospectively studied 92 patients in whom 100 consecutive carotid endarterectomies were performed by a single surgeon (eight procedures were bilateral). Patients were randomly assigned to one of two groups, in which either 0.5 ml of 1% lidocaine was injected into the carotid sinus nerve or no injection of lidocaine was administered before the arteriotomy. All patients were treated postoperatively according to a standard endarterectomy protocol. There were no significant differences between the two groups in the incidence of hypertension, hypotension, or the use of vasoactive medications in the operating room following restoration of carotid artery (CA) blood flow, in the recovery room, or in the intensive care unit. CONCLUSIONS Injection of lidocaine into the carotid sinus at the time of endarterectomy is not associated with a significant improvement in any hemodynamic factor, from the time of restoration of CA blood flow to postoperative Day 1.

Abstract
The first carotid endarterectomy (CEA) is usually accredited to Eastcott who reported in 1954 the successful incision of a diseased carotid bulb with end-to-end anastomosis of the internal carotid artery (ICA) to the common carotid artery (CCA). During the following years surgeons were quick to adopt and improve the intuitively attractive procedure. But by the early to mid 1980s several leading neurologists began to question the growing number of CEAs performed at that time. Six major CEA trials were then designed which are now completed or nearing completion. Most conclusive data are available from the North American Symptomatic Carotid Endarterectomy Trial (NASCET) for symptomatic carotid disease, and from the Asymptomatic Carotid Atherosclerosis Study (ACAS) for asymptomatic carotid disease. The key result of these studies is that CEA is beneficial to high grade symptomatic and asymptomatic carotid stenosis. While the benefit in symptomatic disease is clear, it may be negligible in asymptomatic patients suffering from other medical conditions, the most important being coronary artery disease. Since the conclusions from the different studies vary significantly, guidelines and recommendations with regard to CEA have been issued by a number of interest groups, so-called consensus conferences. The best known guidelines are published by the American Heart Association (AHA). However, the practice of interest groups to issue guidelines is currently being criticized, the main reason being that interest groups have different ideas and all claim the right to issue guidelines. At present we recommend CEA for symptomatic high-grade stenosis in patients without significant coincident disease. With regard to asymptomatic stenosis we suggest surgery to otherwise healthy patients if the stenosis is very narrow or progressive. Preoperative evaluation has changed over the years. Currently we recommend duplex sonography in combination with intra- and extracranial magnetic resonance angiography (MRA). Concurrent coronary artery disease is a major consideration in the perioperative management, and the use of a specific algorithm is recommended. Surgery is performed under general anaesthesia with intraoperative monitoring such as electroencephalography (EEG) and transcranial Doppler (TCD). A temporary intraluminal shunt is used selectively if after cross-clamping the flow velocity in the middle cerebral artery (MCA) falls to below 30 to 40% of baseline. For years we employed routine barbiturate neuroprotection during cross-clamping. At the present time we use barbiturate selectively, if the flow velocity in the MCA falls to below 30 to 40% of baseline and if the use of a temporary intraluminal shunt is not possible due to difficult anatomic conditions. The reason to abandon systematic barbiturate protection was to accelerate recovery from anaesthesia. Our patients are monitored overnight on the ICU or a surveillance unit. Routine hospitalization after surgery is 5 to 7 days with a control duplex sonography being performed prior to discharge. A number of details with regard to surgical technique and perioperative management are a matter of discussion. Our surgical routine is described here step by step. Such management resulted in 6 major complications among the 402 cases with 4 of cardiopulmonary and 2 of cerebrovascular origin. For the future we can expect the development of percutaneous transluminal techniques competing with standard carotid endarterectomy. At the present time several comparative studies are under way. Irrespective of the technical approach to treat carotid stenosis, several other issues have to be clarified before long. One of the major unresolved items is the timing of treatment after completed stroke. In this regard prospective trials need to be performed. Although numerically not as important as carotid stenosis, vertebral artery (VA) and subclavian artery (SA) stenoses are more and more accepted as indication for surgical
