RESUMO

OBJECTIVE: The aim of this study was to assess the relationship between haemoglobin A1c (HbA1c) values and operative wound infection. METHOD: During the period from 2013-2016, consecutive patients with type 2 diabetes were prospectively evaluated. Data were retrospectively analysed. All included patients were admitted for an elective surgical procedure, requiring the use of prosthetic graft in a groin wound. The patients were divided into two groups according to their preoperative HbA1c values. The main outcome was groin wound infection. The association between preoperative long-term glycoregulation and wound infection was evaluated, as well as the impact of postoperative glycaemic values, regardless of the level of HbA1c. RESULTS: Of the 93 participating patients, wound infection occurred in 20 (21.5%). Wound infection occurred in 28.2% of patients with uncontrolled diabetes (HbA1c >7%) and 16.7% of patients with controlled diabetes (HbA1c <7%); however, the difference did not reach statistical significance (p=0.181). In regression modelling, operative time (p=0.042) was a significant predictor of wound infection, while patients' age (p=0.056) was on the borderline of statistical significance. Females had a higher probability for wound infection (odds ratio (OR): 1.739; 95% confidence interval (CI):0.483-6.265), but there was no statistical significance (p=0.397). Patients with elevated levels of HbA1c had a higher chance of wound infection compared with patients with controlled diabetes (OR: 2.243; 95% CI: 0.749-6.716), nevertheless, this was not statistically significant (p=0.149). CONCLUSION: We found no statistically significant correlation between elevated values of preoperative HbA1c and postoperative groin wound infection.

RESUMO

BACKGROUND: Peripheral arterial disease (PAD) and diabetes are the major causes of lower extremity amputations (LEAs) worldwide. Morbidity and mortality in patients with LEAs are high with an associated significant burden on the global health system. The aim of this article is to report the overall morbidity and mortality rates after major and minor LEAs from the Serbian Vascular Registry (SerbVasc), with an analysis of predictive factors that influenced adverse outcomes. MATERIALS AND METHODS: SerbVasc was created in 2019 as a part of the Vascunet collaboration that is aiming to include all vascular procedures from 21 hospitals in Serbia. Prevalence of diabetes among patients with LEAs, previous revascularization procedures, the degree and the type of foot infection and tissue loss, and overall morbidity and mortality rates were analyzed, with a special reference to mortality predictors. RESULTS: In the period from January 2020 to December 2022, data on 702 patients with LEAs were extracted from the SerbVasc registry, mean age of 69.06±10.63 years. Major LEAs were performed in 59%, while minor LEAs in 41% of patients. Diabetes was seen in 65.1% of the patients, with 44% of them being on insulin therapy. Before LEA, only 20.3% of patients had previous peripheral revascularization. Soft tissue infection, irreversible acute ischemia, and Fontaine III and IV grade ischemia were the most common causes of above-the-knee amputations while diabetic foot was the most common cause of transphalangeal and toe amputations. The infection rate was 3.7%, the re-amputation rate was 5.7%, and the overall mortality rate was 6.9%, with intrahospital mortality in patients with above-the-knee amputation of 11.1%. The most significant intrahospital mortality predictors were age >65 years (p<0.001), chronic kidney disease (CKD) (p<0.001), ischemic heart disease (IHD) (p=0.001), previous myocardial revascularization (p=0.017), emergency type of admission (p<0.001), not using aspirin (p=0.041), using previous anticoagulation therapy (p=0.003), and postoperative complications (p<0.001). CONCLUSIONS: The main predictors of increased mortality after LEAs from the SerbVasc registry are age >65 years, CKD, IHD, previous myocardial revascularization, emergency type of admission, not using aspirin, using previous anticoagulation therapy, and postoperative complications. Taking into account high mortality rates after LEAs and a small proportion of previous peripheral revascularization, the work should be done on early diagnosis and timely treatment of PAD hopefully leading to decreased number of LEAs and overall mortality. CLINICAL IMPACT: Mortality after lower limb amputation from the SerbVasc register is high. A small number of previously revascularized patients is of particular clinical importance, bearing in mind that the main reasons for above-the-knee amputations were irreversible ischemia, Fontaine III and Fontaine IV grade ischemia. Lack of diagnostics procedures and late recognition of patients with PAD, led to subsequent threating limb ischemia and increased amputation rates. The work should be done on early diagnosis and timely treatment of PAD in Serbia, hopefully leading to an increased number of PAD procedures, decreased number of LEAs, and lower overall mortality.

RESUMO

Todd's paralysis is a neurological deficit that is observed in <10% of patients following epileptic seizures. Cerebral hyperperfusion syndrome (CHS) is a rare complication following carotid endarterectomy (CEA), seen in 0-3% of the patients, characterized by focal neurological deficit, headache, disorientation, and sometimes seizures. In this case report, we present a case of CHS after CEA followed by seizures and Todd's paralysis that mimicked postoperative stroke. A 75-year-old female patient was admitted for CEA of the right internal carotid artery, following a transient ischemic attack two months prior. Four hours after CEA with graft interposition, the patient suffered a temporary weakness of the left arm and leg followed by generalized spasms within a few seconds. CT angiography showed regular patency of the carotid arteries and the graft, and brain CT showed no sign of oedema, ischemia or hemorrhage. However, left-sided hemiplegia occurred following the seizure, and the patient suffered four more seizures over the next 48 hours, with persisting hemiplegia. On the second postoperative day, the motor skills of the left side fully recovered, and the patient was communicative, and of orderly mental status. Brain CT performed on the third postoperative day showed entire right hemisphere oedema. A moderate hemiparesis with seizures as a consequence of CHS after CEA has been described, however in all cases with seizures and hemiplegia, the underlying cause was always a verified stroke or intracerebral hemorrhage. This case highlights the importance of considering Todd's paralysis in patients with seizures after CEA due to CHS and prolonged periods of hemiplegia after the seizures.

RESUMO

A cohort study was conducted to examine the association of an increased body mass index (BMI) with late adverse outcomes after a carotid endarterectomy (CEA). It comprised 1597 CEAs, performed in 1533 patients at the Vascular Surgery Clinic in Belgrade, from 1 January 2012 to 31 December 2017. The follow-up lasted four years after CEA. Data for late myocardial infarction and stroke were available for 1223 CEAs, data for death for 1305 CEAs, and data for restenosis for 1162 CEAs. Logistic and Cox regressions were used in the analysis. The CEAs in patients who were overweight and obese were separately compared with the CEAs in patients with a normal weight. Out of 1223 CEAs, 413 (33.8%) were performed in patients with a normal weight, 583 (47.7%) in patients who were overweight, and 220 (18.0%) in patients who were obese. According to the logistic regression analysis, the compared groups did not significantly differ in the frequency of myocardial infarction, stroke, and death, as late major adverse outcomes (MAOs), or in the frequency of restenosis. According to the Cox and logistic regression analyses, BMI was neither a predictor for late MAOs, analyzed separately or all together, nor for restenosis. In conclusion, being overweight and being obese were not related to the occurrence of late adverse outcomes after a carotid endarterectomy.

RESUMO

PURPOSE: Carotid artery stenting (CAS) is an option for carotid restenosis (CR) treatment with favorable outcomes. However, CAS has also emerged as an alternative to carotid endarterectomy (CEA) for the management of patients with primary carotid stenosis. This study aimed to report CR rates after CAS was performed in patients with primary lesions versus restenosis after CEA, to identify predictors of CR, and to report both neurological and overall outcomes. MATERIALS AND METHODS: From January 2000 to September 2018, a total of 782 patients were divided into 2 groups: The CAS (prim) group consisted of 440 patients in whom CAS was performed for primary lesions, and the CAS (res) group consisted of 342 patients with CAS due to restenosis after CEA. Indications for CAS were symptomatic stenosis/restenosis >70% and asymptomatic stenosis/restenosis >85%. A color duplex scan (CDS) of carotid arteries was performed 6 months after CAS, after 1 year, and annually afterward. Follow-up ranged from 12 to 88 months, with a mean follow-up of 34.6±18.0 months. RESULTS: There were no differences in terms of CR rate between the patients in the CAS (prim) and CAS (res) groups (8.7% vs 7.2%, χ2=0.691, p=0.406). The overall CR rate was 7.9%, whereas significant CR (>70%) rate needing re-intervention was 5.6%, but there was no difference between patients in the CAS (prim) and CAS (res) groups (6.4% vs 4.7%, p=0.351). Six independent predictors for CR were smoking, associated previous myocardial infarction and angina pectoris, plaque morphology, spasm after CAS, the use of FilterWire or Spider Fx cerebral protection devices, and time after stenting. A carotid restenosis risk index (CRRI) was created based on these predictors and ranged from -7 (minimal risk) to +10 (maximum risk); patients with a score >-4 were at increased risk for CR. There were no differences in terms of neurological and overall morbidity and mortality between the 2 groups. CONCLUSIONS: There was no difference in CR rate after CAS between the patients with primary stenosis and restenosis after CEA. A CRRI score >-4 is a criterion for identifying high-risk patients for post-CAS CR that should be tested in future randomized trials.

RESUMO

The primary aim of the presented study is to analyze and compare the rate of carotid restenosis in patients after eversion carotid endarterectomy (eCEA), primary carotid angioplasty and stenting (CASp), and stenting for carotid artery restenosis after previous eCEA (CASr). The secondary aim is to compare clinical outcomes in patients with carotid restenosis. The total number of patients with evident carotid restenosis was 223 (24.8%). In patients with eCEA, significant carotid restenosis rate was 12.7%, in the CASp group 18.7%, and CASr 6.7%. Patients with carotid restenosis were asymptomatic in 95.1% of cases. Patients in the CASp group experienced transient ischemic attack more than patients with eCEA (P = .007), while no difference was observed regarding cerebrovascular insult (CVI). The incidence of carotid restenosis was higher in CASp patients, and increased during the follow-up. The majority of patients are asymptomatic post-procedural and the degree of carotid restenosis does not correlate with the occurrence of postoperative symptoms. High low-density lipoprotein cholesterol (LDL-C) levels, low high-density lipoprotein cholesterol (HDL-C) levels, smoking, and a history of vascular surgery correlate with higher degrees of carotid restenosis. The most important factor in the prevention of carotid restenosis is risk factor control as well as adequate pharmacological therapy.

RESUMO

As the existing data on the correlation of adiposity with adverse outcomes of carotid endarterectomy (CEA) are inconsistent, the aim of the present study is to examine the correlation of an increased body mass index with 30-day complications after carotid endarterectomy. The cohort study comprises 1586 CEAs, performed at the Clinic for Vascular Surgery in Belgrade, from 2012-2017. Out of them, 550 CEAs were performed in patients with normal body mass index (18.5-24.9), 750 in overweight (25.0-29.9), and 286 in obese (≥30) patients. The association of overweight and obesity with early outcomes of carotid endarterectomy was assessed using univariate and multivariate logistic regression analysis. Overweight patients, in whom CEAs were performed, were significantly more frequently males, compared to normal weight patients-Odds Ratio (OR) 1.51 (95% confidence interval- 1.19-1.89). Moreover, overweight patients significantly more frequently had non-insulin-dependent diabetes mellitus-OR 1.44 (1.09-1.90), and more frequently used ACEI in hospital discharge therapy-OR 1.41 (1.07-1.84) than normal weight patients. Additionally, the CEAs in them were less frequently followed by bleedings-OR 0.37 (0.16-0.83). Compared to normal weight patients, obese patients were significantly younger-OR 0.98 (0.96-0.99), and with insulin-dependent and non-insulin-dependent diabetes mellitus-OR 1.83 (1.09-3.06) and OR 2.13 (1.50-3.01) respectively. They also more frequently had increased triglyceride levels-OR 1.36 (1.01-1.83), and more frequently used oral anticoagulants in therapy before the surgery-OR 2.16 (1.11-4.19). According to the results obtained, overweight and obesity were not associated with an increased death rate, transient ischemic attack (TIA), stroke, myocardial infarction, or with minor complications, and the need for reoperation after carotid endarterectomy. The only exception was bleeding, which was significantly less frequent after CEA in overweight compared to normal weight patients.

RESUMO

INTRODUCTION: Ischemic postconditioning (IPCT) represents one of the several therapeutic strategies to attenuate ischemic reperfusion injury (IR) after carotid endarterectomy (CEA). We here present the first in-human study of IPCT in carotid surgery. METHODS: The study represents an observational case-control study, with the data collected in our Institution carotid database. From December 2015 to December 2020, a total of 300 patients were included in our study; IPCT group consisted of 148 patients in whom ischemic postconditioning was performed while control group consisted of 152 patients in whom IPCT was not performed. Indications for IPCT technique were: severe unilateral internal carotid artery (ICA) stenosis (>90%), severe bilateral ICA stenosis (>80%), severe ICA stenosis (>80%) with contralateral ICA occlusion and ICA subocclusion. IPCT was performed by applying 6 cycles of 30 sec reperfusion (declamping of ICA)/30 sec ischemia (clamping of ICA) after finishing the procedure and initial declamping. Two groups of patients were compared in terms of occurrence of intrahospital and early postoperative stroke, TIA (transient ischemic attack) and neurologic morbidity. RESULTS: Cumulative incidence of intrahospital postoperative stroke or TIA was significantly higher in the control group (5.3% vs 0.7%, P = .036). According to carotid plaque characteristics, patients in the IPCT group had significantly more frequent presence of heterogenous plaque, as well as ulcerated plaque, which was associated with the absence of postoperative stroke and significantly lower cumulative rate of TIA/stroke when compared to the control group (43.9% vs 8% and 47.3% vs 1.5%). During the follow-up period of 1 month after the surgery, there were no cases of stroke, TIA and deaths due to neurological causes in both groups of patients. CONCLUSION: Our results showed that IPCT significantly reduced the incidence of postoperative cerebral ischemic complications after CEA in high-risk patients for IR injury when compared to the control group.

RESUMO

Ralstonia pickettii is an opportunistic bacterium found in the water environment with an increasing incidence as a nosocomial pathogen. The objectives of this study were to describe R. pickettii bacteremia in a cardiac surgery patient and to evaluate its ability to grow in a saline solution and to form biofilm. The patient in this study underwent mitral and aortic valve replacement surgery with two aortocoronary bypasses. She developed signs of respiratory and renal failure, therefore hemodialysis was started. After 25 days in an intensive care unit, the patient had recurrent episodes of fever with signs of bacteremia. R. pickettii was identified from blood cultures by MALDI-TOF MS. Antimicrobial susceptibility testing was performed using disc diffusion and broth microdilution methods in accordance with EUCAST methodology and results were interpreted following clinical breakpoints for Pseudomonas spp. The isolate was susceptible to all tested antimicrobial agents except aminoglycosides and colistin. Survival of R. pickettii was analyzed in saline solution with four different starting concentrations at 25 °C and 37 °C for six days. Biofilm capacity was tested using the microtiter plate method. R. pickettii showed substantial growth in saline solution, with starting concentration of 2 CFU ml-1 reaching 107 CFU ml-1 after six days. There was no significant difference between growth at 25 °C and 37 °C. This indicates that storage of contaminated solutions at room temperature can enhance the count of R. pickettii. Our strain did not show the capacity to form biofilm. The patient responded well to adequate treatment with ceftazidime, and after 48 days in ICU she was discharged to convalesce.

RESUMO

Aneurysms of the splenic artery represent a rare clinical entity, even though they account for 60-70% of all visceral artery aneurysms. Splenic artery aneurysms larger than 5 cm are extremely rare, and they are considered to be giant. Possible causes of splenic artery aneurysm development include: trauma, hormonal and local hemodynamic changes in pregnancy, portal hypertension, arterial degeneration, infection and postsplenectomy occurrence. Surgical treatment of giant splenic artery aneurysms includes procedures that frequently require pancreatectomy and splenectomy. We present a case of a 10.2 cm giant splenic artery aneurysm, firmly adhered to the pancreas, which was treated surgically, with spleen and pancreas preservation. SIMILAR CASES PUBLISHED: Although many cases on treatment of giant splenic artery aneurysm have been published, the majority have described additional visceral resections associated with aneurysmectomy, which is in contrast with our report. Furthermore, aneurysms reaching 10 cm in size were extremely rare.

RESUMO

The rising pandemic of obesity in modern society should direct attention to a more comprehensive approach to abdominal aortic aneurysm (AAA) treatment in the affected population. Although overweight patients are considered prone to increased surgical risk, studies on the subject did not confirm or specify the risks well enough. Associated comorbidities inevitably lead to a selection bias leaning towards endovascular abdominal aortic repair (EVAR), as a less invasive treatment option, which makes it hard to single out obesity as an independent risk factor. The increased technical difficulty often results in prolonged procedure times and increased blood loss. Several smaller studies and two analyses of national registries, including 7935 patients, highlighted the advantages of EVAR over open repair (OR) of abdominal aortic aneurysm, especially in morbidly obese population (relative risk reduction up to 47%). On the other hand, two other studies with 1374 patients combined, concluded that EVAR might not have an advantage over OR in obese patients (P = 0.52). Obesity is an established risk factor for wound infection after both EVAR and OR, which is associated with longer length of stay, subsequent major operations, and a higher rate of graft failure. Percutaneous EVAR technique could present a promising solution to reducing this complication. EVAR seems like a more feasible treatment option than OR for obese patients with AAA, due to lower overall morbidity and mortality rates, as well as reduced wound-related complication rates. However, there is a clear lack of high-quality evidence on the subject, thus future prospective trials are needed to confirm this advantage.

RESUMO

PURPOSE: To present the feasibility, safety, and efficacy of carotid endarterectomy in patients with type II internal carotid artery occlusions, including the long-term outcomes. METHODS: From March 2008 to August 2015, 74 consecutive patients (48 men with a mean age of 65.1 ± 8.06 years) underwent carotid endarterectomy because of internal carotid artery (ICA) segmental occlusions. These were verified with preoperative carotid duplex scans (CDS) and CT angiography (CTA). Also, brain CT scanning was performed in all these patients. The indication for treatment was made jointly by a vascular surgeon, neurologist, and an interventional radiologist in a multidisciplinary team (MDT) context. After successful treatment, all the patients were followed-up at 1, 3, 6, and 12 months, then every 6 months thereafter. RESULTS: The most common symptom at presentation was transient ischaemic attack (TIA) in 49 patients (66.2%), followed by stroke in the past six months in the 17 remaining patients (23%). Revascularisation of the ICA with endarterectomy techniques was performed successfully in all the patients with an average clamp time of 11.9 min. All the procedures were performed under general anaesthesia in combination with a superficial cervical block. The early complication rate was 8.1% and included two cardiac events (2.7%) (one rhythm disorder and one acute coronary syndrome), three TIAs (4.1%), and one intracerebral hemorrhage (1.3%). Only one patient with the intracerebral hemorrhage died 5 days after surgery giving a postoperative mortality of 1.3% for this series. During the follow-up period (mean 50.4 ± 31.3 months), the primary patency rates at 1, 3, 5, and 7 years were 98.4%, 94.9%, 92.9%, and 82.9%, respectively. Likewise, the survival rates were 98.7%, 96.8%, 89%, and 77.6%, respectively. Ultrasound Doppler controls during follow-up detected 8 ICA restenoses; however, only 3 of these patients required further endovascular treatment. CONCLUSIONS: Carotid endarterectomy of internal carotid artery (ICA) segmental occlusion is a safe and effective procedure associated with acceptable risk and good long-term results. Therefore, the current guidelines which do not recommend carotid endarterectomy in this patient group should be reassessed, with the requirement for ongoing large-scale randomized controlled trials to compare CEA with best medical therapy in this patient cohort.

RESUMO

BACKGROUND: Inflammation is one of the mechanisms that leads to carotid restenosis (CR). The aim of this study was to examine the influence of increased values of inflammation markers (high-sensitivity C-reactive protein [hs-CRP], C3 complement, and fibrinogen) on CR development after eversion carotid endarterectomy (CEA). METHODS: A consecutive 300 patients were included in the study, in which eversion CEA was performed between March 1 and August 1, 2010. Demographic data, atherosclerosis risk factors, comorbidities, and ultrasound plaque characteristics were listed in relation to potential risk factors for CR. Serum concentrations of hs-CRP, fibrinogen, and C3 complement were taken just before surgery (6 hours); 48 hours after CEA; and during regular checkups at 1 month, 6 months, 1 year, and 2 years. An "inflammatory score" was also created, which consisted of six predictive values of inflammatory markers (hs-CRP just before and just after CEA, fibrinogen just before and just after CEA, and C3 complement just before and just after CEA) with a maximum score of 6 and a minimum score of 0. At every follow-up visit to the outpatient clinic, ultrasound assessment of the carotid artery for restenosis was done. RESULTS: Our results showed an increased risk of early CR within 1 year in patients with increased hs-CRP before CEA (6 hours) and increased fibrinogen 48 hours after surgery and in patients not taking aspirin after CEA. Sex was determined to be an independent predictor of CR, with female patients having a higher risk (P = .002). Male patients taking aspirin with an inflammatory score >2 had an increased risk for restenosis compared with male patients with inflammatory score <2. Not taking aspirin after CEA and fibrinogen (48 hours) were the strongest predictors, and the Fisher equation incorporating these predictors was used to predict CR. A computer program was created to calculate whether the patient was at high or low risk for CR by selecting whether the patient was taking aspirin (yes or no) and whether fibrinogen was increased 48 hours after CEA (yes or no) and to display the recommended therapeutic algorithm consisting of aspirin, clopidogrel, cilostazol, and statins. CONCLUSIONS: Increased hs-CRP before CEA, increased fibrinogen 48 hours after CEA, and not taking aspirin were the main predictors of early CR. With the clinical implementation of the Fisher equation, it is possible to identify patients at high risk for early CR and to apply an aggressive therapeutic algorithm, finally leading to a decreased CR rate.

RESUMO

Carotid endarterectomy (CEA) carries a significant risk of procedural stroke and death Guidelines recommend keeping this risk below 6% and below 3% for symptomatic and asymptomatic patients respectively. After analyzing our Institute's CEA results during the past 25 years, we found the rate of postoperative complications was now well below Guideline thresholds. Accordingly, we studied temporal changes in procedural risks in randomized controlled trials (RCTs) and in large observational studies in order to compare these against Guidelines. We found a clear temporal trend towards improving procedural outcomes, which can be explained by improvements in medical therapy, more appropriate timing of CEA, the use of local anesthesia and the use of peroperative cerebral monitoring as well as improving surgical techniques. An update of current guidelines should now be undertaken, since our findings are not unique and are supported by other studies in this review.

RESUMO

BACKGROUND: To date, all published studies analyzing simultaneous treatment of carotid and proximal atherosclerotic lesions are describing retrograde approach and several technical variations. In the presented study, for the first time, antegrade approach is described for simultaneous carotid endarterectomy (CEA) and associated brachiocephalic trunk (BCT) or common carotid artery (CCA) angioplasty in the hybrid operating room. METHODS: From January 2012 till January 2016, antegrade hybrid procedures were performed in 18 patients. All patients were admitted to our institute for elective supraaortic arch multidetector computed tomography angiography when significant simultaneous proximal and distal supraaortic arch lesions were revealed. After surgical exposure of carotid arteries, proximal lesions were crossed by antegrade approach. Prior to stent placement, internal carotid artery (ICA) is clamped at its origin with the guidewire placed in the external carotid artery (ECA). After primary stenting and control arteriography, CCA and ECA are clamped and the ICA clamp moved more distally. An arteriotomy is performed in the CCA, with flushing of possible debris and thrombus before performance of the eversion CEA, once again flushing before completion of the anastomosis. Follow-up ranged from 6 to 36 months with average follow-up of 22.15 ± 11.31 months. RESULTS: All procedures went uneventfully. Out of 18 patients, 11 were males and 7 females, mean age 66.6 ± 3.82 years. In 10 patients (55.5%), simultaneous CEA and CCA angioplasty was performed, in 7 patients (38.9%) CEA and BCT angioplasty, and in 1 patient (5.5%) tubular graft interposition between the CCA and the ICA and CCA angioplasty. In 6 patients (33.3%), CCA/BCT balloon angioplasty alone was performed simultaneously with CEA. None of the patient had postoperative transient ischemic attack, stroke, hematoma, dissection, myocardial infarction, or ischemia in the early postoperative period and during the follow-up. There were no lethal outcomes, neither in the early postoperative course nor during the follow-up. CONCLUSIONS: Antegrade approach for simultaneous treatment of proximal CCA/BCT and distal carotid lesions with temporary ICA clamping is safe and feasible procedure that should be thought of in the future in addition to already described retrograde approach.

RESUMO

Endovascular surgery represents a minimally invasive procedure for the treatment of occlusive and aneurysmal arterial disease. However, it is followed by inflammatory response, with a rise in specific inflammatory biomarkers, such as C-reactive protein, serum amyloid A and fibrinogen. Shear stress during balloon inflation and vascular injury represents triggering events for the inflammatory process, stimulating the production of proinflammatory molecules and activation of circulating monocytes. The current literature indicates that stent implantation induces more prominent inflammatory reaction. Additionally, it has been shown that muscular arteries of femoropopliteal segment react to a greater extent to stent implantation, compared with elastic carotid or iliac arteries. The endovascular treatment of thoracic and abdominal aortic aneurysm is frequently followed with post-implantation inflammatory syndrome. Most recent findings point out that stent graft material plays a significant role in the inflammatory response, representing a challenge for clinicians. Future studies should consider the pathophysiology of the inflammatory response associated with endovascular procedures as well as predictors and risk factors including preventive strategies and therapeutic algorithms. Although the potential role of anti-inflammatory drugs after endovascular procedures has been observed, it needs to be validated in upcoming trials. The Neutrophil Lymphocyte Ratio, platelet count, Platelet-to-Lymphocyte Ratio and other biomarkers should be considered in future trials to assess the inflammatory response after endovascular procedures. Inflammatory markers may also become therapeutic targets.

RESUMO

BACKGROUND: Eagle syndrome represents elongated styloid process characterized by calcification and ossification of the stylohyoid ligament rarely associated with the pathology of carotid arteries. We are presenting a very rare case of bilateral Eagle syndrome with associated internal carotid artery (ICA) kinking on the right side and significant ICA stenosis on the left side. CASE REPORT: A 62-year-old female patient was admitted to our Institution for multidetector computed tomography (MDCT) angiography. Two years ago, she experienced stroke with right-sided weakness, color Doppler scan of carotid arteries described left ICA stenosis of 75% and right ICA stenosis of 50%. MDCT arteriography revealed bilateral Eagle syndrome associated with significant left ICA stenosis of >90% and right ICA kinking. Left carotid endarterectomy was performed followed by elongated styloid process resection that was in close relationship to ICA. Even more significant relationship was seen on the right side involving right ICA kinking and elongated styloid process that was treated conservatively. Postoperative course was uneventful; after 6 months, the patient was doing well. CONCLUSIONS: This is the first case that describes bilateral Eagle syndrome associated with ICA kinking on one side and significant stenosis on the other. Although rare, this syndrome should be thought of in symptomatic patients with carotid pathologies in which case computed tomography angiography is of crucial importance.
