Abstract
In recent guidelines of international societies, the most frequent indication for treatment after chronic type B aortic dissection (cTBAD) is aneurysmal dilatation. Endovascular repair is recommended in patients with moderate to high surgical risk or with contraindications to open repair. During the last decade, many advances have been made in the field of endovascular techniques and devices. The aim of this article is to address the current status of endoluminal techniques for the management of cTBAD including standard thoracic endovascular repair, new devices, fenestrated and branched abdominal aortic devices and false lumen occlusion techniques.

Abstract
BACKGROUND Completion imaging has been suggested for the intraoperative quality control assessment of the carotid endarterectomy technical success, in order to immediately resolve pathologic findings and accordingly improve patients' outcome. The aim of this study was to present existing evidence of different completion imaging techniques after carotid endarterectomy and their role on clinical outcome. MATERIAL AND METHODS A systematic review was performed searching in MEDLINE, CENTRAL, and Cochrane databases including studies reporting on completion imaging techniques after carotid endarterectomy. RESULTS A total of 12,378 patients in 35 studies (20 retrospective and 15 prospective) underwent a completion imaging technique after carotid endarterectomy: in 19 studies, 5340 patients underwent arteriography; in 5 studies, 2095 angioscopy; in 21 studies, 5722 DUS; and in 2 studies, 150 patients underwent transcranial Doppler. Ten studies assessed > 1 imaging technique. The mean age was 67 ± 7 years old (69% males) with common co-morbidities to be hypertension (74%), smoking (64%), and hyperlipidemia (54%). Almost half of the patients (4949; 44%) were treated for symptomatic disease. In 1104 (9.7%) patients, a major defect was identified intra-operatively, while in 329 patients (2.9%), a minor defect. Common pathological findings were the presence of mural thrombus, carotid dissection, residual stenosis, and intimal flaps. An immediate re-intervention was undertaken in 75% (790/1053) of the patients to treat a major intra-operative imaging finding. In patients with re-intervention, only 2.3% (14/609) had an intra-operative stroke and 0.8% (5/609), a transient ischemic attack, while only 1.4% (8/575) had a stroke and 0.2% a transient ischemic attack (1/575) during 30-day post-operative period. No intra-operative death was reported. In the same period, the restenosis rate of internal and common carotid artery was 0.5% (3/575) and 0.2% (1/575), respectively. CONCLUSION Completion imaging techniques can detect defects in almost 10% of patients that may lead to immediate intra-operative surgical revision with low intra-operative stroke/transient ischemic attack rate and low early carotid restenosis. During the 30-day follow-up period, in those patients, the incidence of stroke/transient ischemic attack may be low but present. This review cannot provide any evidence on which completion imaging technique is better, and the clinical impact conferred by each technique in the absence of a randomized control studies.

Abstract
BACKGROUND Various techniques have been used for the execution of carotid endarterectomy; primary (PC), patch closure (CP) and eversion technique (ET).The superiority of any of them is still unproven. The aim of this study was to compare the long-term outcomes of each technique in terms of cerebrovascular event (CVE), restenosis, survival and major cardiac event (MACE). METHODS Between 2007 and 2018, a retrospective analysis of prospectively recorded data from three European tertiary centers was undertaken including 1.357 patients. Demographics, comorbidities and medical treatment were analyzed in relation to long-term outcomes. Freedom from CVE, restenosis (> 70%), survival and MACE were estimated with Kaplan-Meier analysis curve. RESULTS The mean age was 69.5 ± 8 (72% males;79% asymptomatic). 472 (35%) were treated with PC, 504 (37%) with CP and 381 (28%) with ET. Differences among groups were observed in age (P < 0.001), gender (P < 0.01), hypertension (P = 0.01), dyslipidemia (P < 0.001) and statin treatment (P < 0.001). The mean follow-up was 4.7 ± 3 years (median: 5 years). Seventy-three patients presented a CVE during 8 years of follow-up. The freedom from CVE including all techniques was 96% (SE 0.6%), 93% (SE 1%) and 89% (SE 1.6%), at 2, 5 and 8 years of follow-up, respectively, with no difference between groups (P .289). Freedom from restenosis was at 96% (SE 0.7%) and 89% (SE 5%) at 5 and 10 years, respectively, for all methods without differences. ET was associated with a higher mortality rate (P < 0.001) and MACE rate (P < 0.001). CONCLUSIONS Excellent outcomes were achieved with all types of closure techniques with low rates of MACE and other adverse events during long-term follow-up after CEA.

Abstract
PURPOSE To describe the implantation steps and tips and tricks for the Inner Branch Arch Endograft designed to treat aortic arch aneurysm and chronic type A aortic dissection. TECHNIQUE Anatomical suitability criteria should be met in order to use this device. The proximal segment of the graft lands in the ascending aorta distally to the sinotubular junction and the distal segment lands in the descending aorta. The device includes 2 inner branches; the proximal branch is used for a connection to the innominate artery (positioned slightly posterior at 12:30 o'clock), while the second branch is positioned slightly anterior at 11:30 o'clock and is used as a connection to the left common carotid artery. Access, implantation technique, deployment of the device, and catheterization of the branches are described thoroughly. CONCLUSION This Inner Branch Arch Endograft is an appealing alternative to treat aortic arch pathology, especially in patients unsuitable for open repair. Nevertheless, complex aortic arch repair is associated with a learning curve. Meticulous preoperative planning and a high level of concentration intraoperatively are mandatory.

Abstract
OBJECTIVE The purpose of this study was to evaluate the outcome of t-Branch (Cook Medical, Bloomington, Ind) stent graft for the treatment of thoracoabdominal and pararenal aortic aneurysms in patients who had previous infrarenal aortic repair. METHODS A retrospective two-center study was undertaken. All consecutive patients who underwent endovascular repair using t-Branch stent graft after previous infrarenal aortic repair between January 2010 and August 2018 were included. Demographics, past medical history, cardiovascular risk factors, and intraoperative and perioperative details were recorded. Technical success and early (30-day) mortality, morbidity, target vessel patency, and presence of endoleak were analyzed. During the first year of follow-up, survival, freedom from reintervention, and patency rates were recorded. RESULTS There were 32 patients (mean age, 74 ± 7 years; 81% male) included in the study; 24 (75%) patients had prior open surgical repair, and 8 (25%) patients had undergone standard endovascular aneurysm repair. The index operation was performed 9 ± 5 years earlier, including 10 ± 5 years for open surgical repair and 8 ± 6 years for endovascular aortic repair. The indication was progression of the disease in 26 patients (81%) and type IA endoleak in 6 patients (19%). The total number of target vessels incorporated was 117 arteries (3.8 ± 0.6 target vessels per patient). Eleven patients had only three vessels incorporated; celiac trunk was occluded in three patients, and eight patients had one functioning kidney. Technical success rate was 97% (31/32). There was a single technical failure in one patient who had a type IA endoleak after endovascular repair with suprarenal fixation. The stenotic right renal artery was not catheterized at the initial procedure, and retrograde access was achieved through a right subcostal incision 3 days later with successful completion of the repair. Early mortality rate was 13%, and spinal cord ischemia rate was 22% (7/32); four patients had permanent and three had transient neurologic deficits. Early target vessel patency was 100%, and the rate of any endoleak was 9% (3/32); two patients had type II endoleaks and one patient had type III endoleak. The mean follow-up was 5.4 ± 5.9 months. The cumulative survival rate was 82% and 73% at 6 and 12 months, respectively. The freedom from aorta-related mortality was 92% at 6 and 12 months. The cumulative freedom from reintervention during follow-up was 90% at 6 and 12 months. The overall target vessel patency rate was 100% and 97.5% at 6 and 12 months, respectively. CONCLUSIONS The use of t-Branch off-the-shelf stent graft for the treatment of aortic disease in patients who had previous infrarenal aortic repair appears to be feasible, with acceptable early outcomes in terms of morbidity and mortality.

Abstract
BACKGROUND Screening program in lower extremity atherosclerotic disease (LEAD) has not been widely implemented from health systems. The aim of this study was to assess the incidence of LEAD in Greece though a pilot LEAD screening program. METHODS Males >60 years old without known diagnosis of LEAD or chronic renal disease were invited through public primary health care institutions to participate in a pilot screening program in Central Greece. Demographics, atherosclerotic risk factors and other comorbidities were recorded. LEAD was defined as ankle-brachial pressure index (ABPI) of <0.9 or >1.4. RESULTS Among a total of 1152 individuals (invitation acceptance 70%; 1152/1638) LEAD was detected in 13% (148); including 7% with ABPI<0.9 and 6% with ABPI>1.4. Comparing the groups with ABPI<0.9 vs. normal ABPI, abnormal ABPI was associated with older age (P=0.001), hypertension (HT) (P=0.037), smoking (P=0.002), duration of smoking (P=0.01), packs/year (P=0.002), coronary artery disease (P=0.02), chronic obstructive pulmonary disease (P=0.028) and cerebrovascular disease (P=0.001). After multivariate analysis, increased age (0.94, CI: 0.026-5.2; P=0.022), history of HT (2.4, CI: 0.44- 3.7; P=0.05) and longer duration of smoking (0.9, CI: 0.01-6.1; 0.013) were associated with ABPI <0.9. Abnormally higher ABPI (>1.4) was not associated with any factor. Among those without known CAD or CVD (96/148), 37.5% (36/96) were on statins and 21% (20/96) on antiplatelets. CONCLUSIONS Incidence of LEAD was 13% in a male >60 years-old population of central Greece; these individuals maybe undertreated. ABPI<0.9 was diagnosed in 7% and was associated with older age, HT and duration of smoking.

Abstract
BACKGROUND Infection with human papillomaviruses (HPVs) can cause benign and malignant tumours in the anogenital tract and the oropharynx both in men and women. The aim of the presented study was to investigate cervical, anal, and oral HPV-detection rates among women referred to colposcopy for abnormal Cervical Cancer (CaCx) screening results and assess the concordance of HPV-types among these anatomical sites. METHODS Women referred to colposcopy at a single centre due to abnormal cytology, conducted for CaCx screening, were subjected to cervical Liquid-based Cytology (LBC) smear testing, anal and oral sampling. Routine colposcopy consisted in multiple biopsies and/or Endocervical Curettage (ECC). HPV-detection was performed by PCR genotyping in all three anatomical sites. In high-risk (hr) HPV-DNA positive samples either from anal canal or oral cavity, anal LBC cytology and anoscopy were performed, or oral cavity examination respectively. Descriptive statistics was used for the analysis of HPV-detection rates and phi-coefficient for the determination of HPV-positivity concordance between the anatomical sites. RESULTS Out of 118 referred women, hr. HPV-DNA was detected in 65 (55.1%), 64 (54.2%) and 3 (2.5%) at cervix, anal canal and oral cavity respectively while low-risk HPV-DNA was detected in 14 (11.9%) and 11 (9.3%) at cervix and anal canal respectively. The phi-coefficient for cervix/anal canal was 0.392 for HPV16, 0.658 for HPV31, 0.758 for HPV33, - 0.12 for HPV45, 0.415 for HPV52 and 0.473 for HPV58. All values were statistically significant (p < 0.001). CONCLUSIONS The results suggest that most HPV-types, high-risk and low-risk, detected in the cervix of women with prevalent cervical dysplasia, correlate with the ones detected in their anal canal. This particularly applies for the HPV-types included in the nonavalent HPV-vaccine (HPVs 6/11/16/18/31/33/45/52/58).

Abstract
Aim:
The effect of endovascular aneurysm repair in patients treated for abdominal aortic aneurysm has
not been clearly defined. The objective of the present article was to provide a contemporary literature review and
perform an analysis to determine the effect of EVAR on renal function in the early post-operative period and
during follow-up.
Methods:
A systematic review of the literature was undertaken to identify all studies reporting the effect of
EVAR on renal function. Outcome data were pooled and combined overall effect sizes were calculated using
fixed or random-effects models.
Results:
Thirty-two studies reporting on 24846 patients were included. Acute renal failure after EVAR occurred
with an estimated frequency of 9% (95%CI: 5-16%; I2=97%). Median follow-up period was 19.5 months (range
1-60 months). The estimated frequency of chronic renal failure during follow-up was 7% (95%CI: 3-17%;
I2=98%). Hemodialysis was required in 2% (1-3%; I2=97%) of the cases.
Conclusion:
High-level evidence demonstrating the effect of EVAR on the incidence of acute and chronic renal
failure is lacking. Based on the current available data, nearly 10% of patients undergoing EVAR for AAA have an
increased risk for renal dysfunction after the procedure. Whether this deterioration may lead to a worse outcome
has not been adequately proved.

Abstract
Purpose: To present a case of endovascular repair using a custom-made 7-branch stent-graft for a thoracoabdominal aortic aneurysm (TAAA) in a patient with variations in the renovisceral artery anatomy. Case Report: A 70-year-old asymptomatic man presented with a 60-mm-diameter type IV TAAA. Due to severe coronary artery disease, an endovascular approach was elected. In the preoperative computed tomography angiography (CTA) scans, variations in the renovisceral artery anatomy included the common hepatic and splenic arteries deriving separately from the aorta and bilateral double renal arteries (RAs). A custom-made 7-branch stent-graft was manufactured to preserve all renovisceral arteries. The 7 branches were catheterized and connected with a steerable sheath from a femoral access. All branches were bridged to the target vessel (TV) with a self-expanding covered stent; 4 TVs also had balloon-expandable covered stents implanted. Final angiography and predischarge CTA showed patency of all 7 target vessels and corresponding visceral organs, with no endoleak. The patient was discharged on postoperative day 8 without complications. Six-month follow-up CTA demonstrated exclusion of the TAAA and patency of all 7 target vessels. Conclusion: Successful treatment of a TAAA in a patient with multiple variant renovisceral arteries was feasible with a custom-made 7-branch stent-graft, achieving a good early outcome.

Abstract
Objective: Growing evidence indicates that depressive disorders (DDs) are an important risk factor for atherosclerosis. The aim of this study was to evaluate the presence of common carotid artery (CCA) intima-media thickness (IMT) and circulation inflammation markers in patients with DD. Methods: A cross-sectional prospective study was undertaken comparing 40 patients with DD to 40 individuals free of depression, matched for age and gender. The Beck Depression Inventory questionnaire, serum total cholesterol, triglycerides, high-sensitivity C-reactive protein, interleukin-6, tumor necrosis factor α, P-selectin, and E-selectin levels were measured. The CCA-IMT was assessed with duplex sonography. Results: Patients with DD were more likely to smoke (65% vs 40%; P = .03) and have higher levels of serum total cholesterol (211 mg/dL vs 181 mg/dL; P = .010), triglycerides (138 mg/dL vs 97 mg/dL; P = .005), and P-selectin (0.87 ng/mL vs 0.61 ng/mL; P = .05) and lower levels of interleukin 6 (4.4 ± 2.1 pg/mL vs 10.3 ± 1.1 pg/mL; P = .002). The CCA-IMT was similar in both groups (0.07 ± 0.02 cm vs 0.06 ± 0.01 cm; P = .31). Among those with CCA-IMT in the upper quartile, subjects in the DD group had lower levels of interleukin 6 ( P = .05) and triglycerides ( P = .01) and higher levels of soluble P-selectin ( P = .03). Conclusion: Patients with DD do not present with higher CCA-IMT than a control group, although smoking and a higher level of serum lipids are present. Inflammatory biomarkers seem to be higher in patients with DD.
