Abstract
Objective Abdominal aortic aneurysms are a major cause of death in developed countries, and thrombus and calcification of the aneurysm have been linked to increased complications. This study was conducted in order to identify the biochemical marker associated to the presence of intraluminal thrombus or calcification progression of the aneurysm. Design Several clinical laboratory parameters were measured in patients with abdominal aortic aneurysms, in particular those already demonstrated to be related to the pathology, such as lipoprotein (a), white blood cell count, fibrinogen and high-sensitivity C-reactive protein. Most of the patients were analysed for the presence of thrombus or aorta calcification using CT angiography. Results Unlike previous findings, we found no association between intraluminal thrombus formation and lipoprotein (a), but we evidenced that patients with lower grade of calcification tend to have higher plasma high-sensitivity C-reactive protein values compared with patients with a higher degree of calcification. Instead, no association was found with either white blood cell count or fibrinogen level. Conclusions This study suggests that high-sensitivity C-reactive protein is a useful biomarker to assess the evolution of calcification and could be used in triaging patients to identify those who should undergo a rapid imaging, thus allowing prompt initiation of treatment or rule-out suspicious patients from non-essential imaging repetition.

Abstract
BACKGROUND About one-third of candidates for transcatheter aortic valve implantation (TAVI) suffer from severe peripheral artery disease, making the routine femoral approach difficult or impossible. The aim was to compare the transaxillary (TAx) and the transaortic (TAo) route for TAVI with Medtronic CoreValve Revalving System (CRS). METHODS Out of 1049 consecutive TAVI with 18F CRS, 242 (23%) were treated in 4 high-volume Italian Centre through TAx (61%) and TAo (39%). RESULTS The devices success was similar (P=0.16) with a trend to a lower incidence of significant paravalvular leak (6% vs. 14%, P=0.07) and a significant reduction of permanent pacemaker (PPM) implantation (13% vs. 34%, P=0.017) in the TAo. However, this route showed a higher incidence of acute kidney injury (P=0.016) and a longer hospital stay after the index procedure (days 10 [8-14] vs. 8 [7-12], P=0.001). By a multivariate analysis the vascular access is an independent predictor for a longer hospital stay (TAo route; OR=0.37, 95% CI: 0.18-0.75; P=0.006) and for PPM implantation (TAx route; OR=3.7, 95% CI: 1.2-10.8; P=0.017). CONCLUSIONS Although the higher clinical risk profile of transaortic population, the TAo approach showed an equally high device success with similar 30-day safety and 1year efficacy, compared to TAx route. However, due to non-procedure-specific complications post-TAo TAVI, this route requires a specialized postoperative care and the treatment of patients in highly specialized and experienced centers.

Abstract
From January to November, 1985, 43 carotid bifurcation endarterectomies (CE) were performed with intraoperative functional (Doppler spectrum analy sis) and morphologic (angiography) controls. In the first 20 cases, after thromboendarterectomy and direct suture, Dop pler showed absence of or no significant variations of frequency in 17 cases, a frequency increase corresponding to a less than 45% diameter reduction steno sis at the apex of the suture in 2 cases, and no flow in the internal carotid artery (ICA) in 1 case. Angiography confirmed the thrombosis in the above mentioned case and showed 3 less than 50% stenoses at the distal end of the arteriotomy: 2 already recognized by Doppler in small-size ICAs and 1 in a medium-size ICA without significant changes of flow. The reason for thrombosis was a distal intimal flap, which was successfully removed; the 2 stenoses in which Doppler and angiography agreed were corrected by patch angioplasty. In the last 23 cases, patch angioplasty was performed routinely in small-size ICAs (6 cases); in 1 case, first treated by a direct suture, Doppler and angiography showed a medium-grade stenosis, immediately corrected; in 1 case both techniques showed a 50% stenosis in a common carotid artery, immediately corrected. The execution of intraoperative angiography in this group of patients al lowed the authors to define the indication for the use of patch angioplasty, never previously employed. Nevertheless, the authors state that, on account of loss of time, costs, and exposure to radiations, intraoperative angiography must be reserved for those cases selected by Doppler spectrum analysis. This method seems to be highly sensitive in recognizing significant technical defects that could lead to an immediate or late failure.

Abstract
Doppler above-ankle pressure index (API) was monitored during 368 consec utive bilateral aortoiliac or aortofemoral graft reconstructions performed for aneurysmal or occlusive disease. The aim of this study was to investigate the variations of peripheral pressure, during and just after completion of the proce dure, either when followed by immediate and definitive success or when an intraoperative correction or an early postoperative reoperation was necessary owing to postreconstructive ischemia. For this purpose the API courses were subdivided into three groups: A (705 limbs), which underwent immediately suc cessful reconstructions; B (22 limbs), which needed intraoperative correction; C (9 limbs), which required early reoperation. All 736 limbs were studied individ ually as monolateral reconstructions and classified into six subgroups: 1, pervi ous iliac, pervious femoral artery; 2, occluded iliac, pervious femoral; 3, pervi ous iliac, stenotic femoral (i.e, stenosis > 75% of the superficial femoral artery); 4, occluded iliac, stenotic femoral; 5, pervious iliac, occluded femoral; 6, oc cluded iliac, occluded femoral. APIs were monitored before the operation (PRE), at the completion of the distal anastomosis (DEC), and five, fifteen, thirty, and forty-five minutes after. Data were statistically analyzed by multivariate analysis in regards to 705 immediately successful limbs (group A) and by comparison of all corrected or reoperated cases (groups B and C) with the lower bound of the fifth centiles of group A. The results in group A show that: API-PRE is different in the six subgroups (p < 0.001); API-DEC is lower than API-PRE in the patent iliac artery sub groups (1,3, and 5) and higher than API-PRE in the occluded iliac artery sub groups (2,4, and 6) (p always < 0.001). From declamping time to the forty-five- minutes observation, the mean courses turn out parallel and rising but on dif ferent levels (p < 0.001): pervious femoral, stenotic femoral, occluded femoral. API-forty-five minutes is higher than API-PRE in occluded iliac artery subgroups (2, 4, and 6) (p < 0.001), whereas in the patent iliac artery subgroups only the fifth subgroups reveals a slight but significant rise (p < 0.01), probably owing to the high rate of profunda femoral endarterectomy or angioplasty asso ciated with aortofemoral reconstructions. APIs values of 31 cases in groups B and C, compared with the lower bound of the fifth centile of group A, show that 8/31 cases (26%) remain above that bound, while 23/31 cases (74%) fall below it.

Abstract
The purpose of this article is to report successful hybrid treatment of a sovraprosthetis type IV thoracoabdominal aneurysm. This technique was used in a 65-year-old man with chronic rupture of a type IV thoracoabdominal aneurysm not suitable for aortic cross-clamping because of a severe cardiopathy (left ventricular ejection fraction 20%); the patient underwent previous repairs of aortic arch and infrarenal abdominal aortic aneurysms. Perioperative complications were absent. Postoperative day 21 computed tomography and monthly duplex ultrasonography confirmed the complete exclusion of the aneurysm with proper perfusion of visceral vessels. At the seventh postoperative month, the patient died of a massive recurrence of myocardial infarction. Hybrid treatment for thoracoabdominal aneurysms may represent a valid solution for those patients with poor cardiac and respiratory reserve, reducing cardiac stress and the duration of visceral ischemia, which are still the main causes of morbidity and mortality for this type of intervention.

Abstract
OBJECTIVE To compare different vascular approaches on clinical outcome of patients undergoing transcatheter aortic valve implantation (TAVI) with self-expandable bioprosthesis. METHODS We included all the patients undergoing CoreValve implantation at our institute between September 2007 and March 2014. They were divided into four groups based on the vascular approach: percutaneous transfemoral (pTF), cut-down transfemoral (cTF), transaxillary (TAx) and transaortic (TAo). Clinical outcomes were evaluated according to Valve Academic Research Consortium-2 recommendations. RESULTS Out of 322 consecutive patients, 170 (53%) underwent pTF, 76 (23%) cTF, 32 (10%) TAx and 44 (14%) TAo approach. Although the TAx and TAo patients had a higher risk profile, they had a similar outcome compared with the pTF and cTF groups; in particular, there were no differences regarding cardiovascular and all-cause mortality at 30 days, 1 and 2 years, as well as stroke, myocardial infarction, bleeding, major vascular complications, permanent pacemaker implantation and acute kidney injury rates. The observed device success rate was higher in the TAo than in the other approaches (88.6 versus 65.9, 68.7 and 76.3% in the pTF, cTF and TAx groups, respectively; P = 0.019). No differences occurred regarding 30-day early safety and 1-year clinical efficacy across the four groups. Fluoroscopy time, amount of contrast medium used and minor vascular complications were significantly higher in pTF patients, as well as in-hospital stay in the TAo group. Atrial fibrillation and prosthetic valve regurgitation, but not the vascular approach, were independent predictors of all-cause mortality. CONCLUSION A more invasive vascular approach, for CoreValve implantation, even in higher risk patients, does not affect early-term, mid-term and long-term outcomes.

Abstract
To date, the pathogenesis of abdominal aortic aneurism (AAA) still remains unclear. As such, the aim of this study was to evaluate changes of the aortic structure during AAA. We analysed the microscopic frame of vessels sections, starting from the primum movens leading to abnormal dilatation. AAA samples were collected and processed through various staining methods (Verhoeff-Van Gieson, Masson Goldner, Sirius Red). Subsequently, the vessel morphology and collagenic web of the tunica media and adventitia were determined and the amount of type I and type III collagen was measured. We also applied immune-histochemistry markers for CD34 and PGP 9.5 in order to identify vascular and nerve structures in the aorta. Immune-positivity quantification was used to calculate the percentage of the stained area. We found increasing deposition of type I collagen and reduced type III collagen in both tunica media and adventitia of AAA. The total amount of vasa vasorum, marked with CD34, and nerva vasorum, marked with PGP 9.5, was also higher in AAA samples. Cardiovascular risk factors (blood pressure, dyslipidemia, cigarette smoking) and radiological data (maximum aneurism diameter, intra-luminal thrombus, aortic wall calcification) increased these changes. These results suggest that the tunica adventitia may have a central role in the pathogenesis of AAA as clearly there are major changes characterized by rooted inflammatory infiltration. The presence of immune components could explain these modifications within the framework of the aorta.

Abstract
INTRODUCTION Magnesium exerts analgaesic effects in several animal pain models, as well as in patients affected by acute postoperative pain and neuropathic chronic pain. There is no evidence that magnesium can modulate pain in patients with peripheral arterial occlusive disease (PAOD). We describe the protocol of a single-centre randomised double-blind clinical trial aimed at assessing the efficacy of oral magnesium supplementation in controlling severe pain in patients with advanced PAOD. METHODS AND ANALYSIS Adult patients affected by PAOD at stages III and IV of Lèriche-Fontaine classification, who are opioid-naïve, and who have been admitted to our Acute Pain Service for intractable pain, will be eligible. Patients will be randomised to the control group, treated with standard therapy (oxycodone and pregabalin) plus placebo for 2 weeks, or to the experimental group (standard therapy plus magnesium oxide). Patients will be evaluated on days 0, 2, 4, 6, 8, 12 and 14; the following information will being collected: daily oxycodone dose; average and maximum pain (Numerical Rating Scale); pain relief (Pain Relief Scale); characteristics of the pain (Neuropathic Pain Scale); impact of pain on the patient's daily activities (Brief Pain Inventory). The primary outcome will be oxycodone dosage needed to achieve satisfactory analgaesia on day 14. Secondary outcomes will be pain relief on day 2, time needed to achieve satisfactory analgaesia and time needed to achieve a pain reduction of 50%. A sample size calculation was performed for the primary outcome, which estimated a required sample size of 150 patients (75 per group). ETHICS AND DISSEMINATION Ethical approval of the study protocol has been obtained from Comitato Etico Provinciale di Brescia, Brescia, Italy. Trial results will be disseminated through scientific journal manuscripts and scientific conference presentations. TRIAL REGISTRATION NUMBER NCT02455726.

Abstract
Aortic atherosclerosis is the most common disease of the aorta. More than 50% of the plaques thicker than 4 mm are located along the descending aorta. The complex morphology of the plaque, such as ulceration or the presence of thrombi, is associated with increased embolic risk. The increasing use of transesophageal echocardiogram has enhanced the recognition of aortic atheromas. We describe a case of a male patient with complex atherosclerotic disease involving the coronary vessels and descending aortic tract with some embolic complications.

Abstract
Mild vascular cognitive impairment (mVCI) is a broader term that is intended to detect cognitive loss before the development of dementia. The identification of preventable risk factors as well as therapeutic strategies of intervention is still unclear. It has been suggested that carotid endarterectomy (CEA) improves cognitive functions, beyond the well-known preventive effect upon future stroke events. In the present study, we evaluated the beneficial effect of CEA in restoring mVCI. Among a large sample of subjects, who underwent CEA for severe carotid stenosis, two groups were identified according to the absence (CON) or the presence of cognitive impairment (mVCI). A multidimensional neuropsychological and behavioural assessment was performed in the week prior, and at a 3-month follow-up after CEA. The incidence of mVCI in this sample was 38%. Seventy-eight patients completed the follow-up (48 CON, 30 mVCI). Both groups showed a clinical improvement after CEA, although the effect was significantly higher in the mVCI group in regard to verbal memory (short story, p < 0.05), and attention (digit span, p < 0.05) scores. At follow-up, 60% of mVCI subjects were classified as having normal cognitive functions. Index of disease severity and peripheral arterial disease were found to be the predictors of improvement. These findings support that mVCI represents a heterogeneous, in some cases reversible condition. CEA might be considered a therapeutic option to treat and prevent cognitive decline in mVCI patients.

Abstract
Several studies have suggested that infectious agents may induce the development of abdominal aortic aneurysms and/or accelerate their progression. The aim of this study was to evaluate the presence of the respiratory-transmitted viruses such as influenza A and B and parainfluenza type 1 genomes in bioptic fragments of abdominal aortic aneurysms. Furthermore, the association between viral infection and traditional risk factors for aneurysms was investigated employing multivariate logistic regression models. The genome of parainfluenza 1 was detected in 11 out of 57 patients with abdominal aortic aneurysm, influenza A only in one, whereas none of the specimens analyzed resulted positive for influenza B. After adjustment of age, gender, and clinical diagnosis, being current smokers was associated independently with parainfluenza 1 detection in aneurysms. The identification of parainfluenza 1 in aortic aneurysm biopsies supports previous observations of a possible role of viruses in the lesion development. Smoking, by interfering with the respiratory tract's ability to defend itself and predisposing to upper and lower respiratory tract infections may accelerate the onset and progression of abdominal aortic aneurysms.

Abstract
The crossover femoro-femoral bypass, classically used for the treatment of unilateral iliac arterial obstruction, has recently become an integral part of aorto-uni-iliac endovascular aneurysm repair. We therefore, reconsider the therapeutic problems related to thrombosis and in particular to infection of the femoro-femoral prosthesis, when many attempts have been made to preserve the bypass and treat the infection. Showing a case treated and well eight months later, we put forward the old technique of crossover ilio-iliac bypass, followed by the removal of the infected femoro-femoral graft. In our opinion, this technique circumvents the need for autologous tissue and allows for the use of prosthetics in a new, sterile, uncontaminated field. As this approach for these cases has so far not been reported in the literature, further cases and long-term follow-up are needed.

Abstract
BACKGROUND Peripheral arterial disease (PAD) is a disease affecting million of patients worldwide. Though traditional cardiovascular risk factors have been associated with the development of PAD, the possible existence of an inherited genetic predisposition to PAD has been investigated in few familial aggregation studies. A link between genetics and PAD may open new avenues for the prevention of this morbid and mortal disorder. AIM The aim of this study is to investigate a possible role of some genetic determinant involving into coagulation and homocysteine metabolism in the progression of PAD. MATERIALS AND METHODS We follow one-hundred patients affected by PAD for six years. We evaluated Ankle-Brachial Index (ABI) two times; first at the time of recruitment and then after six years, in order to assess the progression of disease. Genotypes for the genes of Factor V Leiden, Prothrombin or Factor II G20210A, Cystathionine Beta-Synthase 844ins68bp and Methylenetetrahydrofolate Reductase C677T was ascertained after taking blood samples. Chi-square test was performed to determinate the possible correlation of these genes and the most common environmental factors in the progression of PAD. RESULTS Genetic disorders resulting in high level of homocysteina or thrombophilic phenotype are not so frequent. None among the genetic factors we considered were correlated with PAD. CONCLUSION PAD is a chronic disease whose course can be slowed down especially with the control of environmental risk factors. Genetic analyses are not useful to determine the disease progression or its tendency to remain stable.

Abstract
BACKGROUND: The literature does not support the choice between open and laparoscopic management of splenic artery aneurysms (SAA). METHODS: We designed a prospective, randomized comparison between open and laparoscopic surgery for SAA. Primary end points were types of surgical procedures performed and clinical outcomes. Analysis was developed on an intention-to-treat basis. RESULTS: Fourteen patients were allocated to laparotomy (group A) and 15 to laparoscopy (group B). Groups displayed similar patient- and aneurysm-related characteristics. The conversion rate to open surgery was 13.3 %. The type of surgical procedure performed on the splenic artery was similar in the two groups: aneurysmectomy with splenic artery ligature or direct anastomosis was performed in 51 % and 21 % of patients in group A and in 60 % and 20 % in group B, respectively. The splenectomy rate was similar (14 % vs. 20 %). Postoperative splenic infarction was observed in one case in each group. Laparoscopy was associated with shorter procedures (p = 0.0003) and lower morbidity (25 % vs. 64 %, p = 0.045). Major morbidity requiring interventional procedures and blood transfusion was observed only in group A. Laparoscopy was associated with quicker resumption of oral diet (p < 0.001), earlier drain removal (p = 0.046), and shorter hospital stay (p < 0.01). During a mean follow-up of 50 months, two patients in group A required hospital readmission. In group B, two patients developed a late thrombosis of arterial anastomoses. CONCLUSIONS: Our study demonstrates that laparoscopy permits multiple technical options, does not increase the splenectomy rate, and reduces postoperative complications. It confirms the supposed clinical benefits of laparoscopy when ablative procedures are required but laparoscopic anastomoses show poor long-term results.

Abstract
Background The ergotamine tartrate associated with certain categories of drugs can lead to critical ischemia of the extremities. Discontinuation of taking ergotamine is usually sufficient for the total regression of ischemia, but in some cases it could be necessary thrombolytic and anticoagulant therapy to avoid amputation. Case report A woman of 62 years presented with a severe pain left forearm appeared 10 days ago, with a worsening trend. The same symptoms appeared after 5 days also in the right forearm. Physical examination showed the right arm slightly hypothermic, with radial reduced pulse in presence of reduced sensitivity. The left arm was frankly hypothermic, pulse less on radial and with an ulnar humeral reduced pulse, associated to a decreased sensitivity and motility. Clinical history shows a chronic headache for which the patient took a daily basis for years Cafergot suppository (equivalent to 3.2 mg of ergotamine). From about ten days had begun therapy with itraconazole for vaginal candidiasis. The Color-Doppler ultrasound shown arterial thrombosis of the upper limbs (humeral and radial bilateral), with minimal residual flow to the right and no signal on the humeral and radial left artery. Results Angiography revealed progressive reduction in size of the axillary artery and right humeral artery stenosis with right segmental occlusions and multiple hypertrophic collateral circulations at the elbow joint. At the level of the right forearm was recognizable only the radial artery, decreased in size. Does not recognize the ulnar, interosseous artery was thin. To the left showed progressive reduction in size of the distal subclavian and humeral artery, determined by multiple segmental steno-occlusion with collateral vessels serving only a thin hypotrophic interosseous artery. Arteriographic findings were compatible with systemic drug-induced disease. The immediate implementation of thrombolysis, continued for 26 hours, with heparin in continuous intravenous infusion and subsequent anticoagulant therapy allowed the gradual disappearance of the symptoms with the reappearance of peripheral pulses. Conclusion Angiography showed regression of vasospasm and the resumption of flow in distal vessels. The patient had regained sensitivity and motility in the upper limbs and bilaterally radial and ulnar were present.

Open surgery in endovascular aneurysm repair era: simplified classification in two risk groups owing to factors affecting mortality in 137 ruptured abdominal aortic aneurysms (RAAAs).

Abstract
Our objective is to identify in 137 true RAAAs operated consecutively in open surgery: (1) diagnostic therapeutic aspects capable of influencing results, (2) risk classes with different prognosis, (3) any situations where the prognosis is so negative that surgery is not recommended. The relationship of 16 anamnestic, clinical and technical parameters prospectively collected with 30-day mortality was retrospectively evaluated by uni- and multivariate analyses. Thirty-day mortality was 37%. The univariate analysis identified as mortality predictors Hb ≤ 8 g/dl and circulatory shock at hospitalisation, but following the multivariate analysis only circulatory shock was a certainly significant risk-factor. The cumulative effect on mortality of the two parameters identified at univariate analysis translates into a statistically significant difference in mortality between two groups of patients: A (no or just one risk-factor) and B (two risk-factors). To reinstate euvolemia, rather than adequate haemoglobin values, improves the chances of success. A simple prognostic index into two risk classes is feasible, but abstention from surgery is not justified in any type of patient.

Abstract
Endothelial cells (ECs) are a site of human cytomegalovirus (HCMV) productive replication, haematogenous dissemination and persistence, and are assumed to play a critical role in the development of HCMV-associated vascular diseases. Although early reports have shown the presence of HCMV antigens and DNA in lymphoid tissues, the ability of HCMV to infect lymphatic ECs (LECs) has remained unaddressed due to the lack of a suitable in vitro system. This study provided evidence that a clinical isolate of HCMV (retaining its natural endotheliotropism) was able to productively infect purified lymph node-derived LECs and that it dysregulated the expression of several LEC genes involved in the inflammatory response to viral infection. Qualitative and quantitative analysis of virus-free supernatants from HCMV-infected LEC cultures revealed virus-induced secretion of several cytokines, chemokines and growth factors, many of which are involved in the regulation of EC physiological properties. Indeed, functional assays demonstrated that the secretome produced by HCMV-infected LECs stimulated angiogenesis in both LECs and blood ECs, and that neutralization of either interleukin (IL)-6 or granulocyte-macrophage colony-stimulating factor (GM-CSF) in the secretome caused the loss of its angiogenic properties. The involvement of IL-6 and GM-CSF in the HCMV-mediated angiogenesis was further supported by the finding that the recombinant cytokines reproduced the angiogenic effects of the HCMV secretome. These findings suggest that HCMV induces haemangiogenesis and lymphangiogenesis through an indirect mechanism that relies on the stimulation of IL-6 and GM-CSF secretion from infected cells.

Abstract
Lesions of the isthmus are the most frequent among post-traumatic lesions of the thoracic aorta (LTA): almost always secondary to closed thoracic traumas (road accidents, falls, crushing, and explosions), they are rarely iatrogenic (operatory catheterisms) or caused by penetrating wounds. In the review of the literature concerned in the report, from the analysis of 89 bibliographic sources, we note that the etiopathogenesis and the pathophysiology of the LTA still entail a very high immediate mortality, but we also note that, in recent years, remarkable improvements have been made not only in prevention, first-aid, diagnostic definition and in the understanding of the development of the LTA, but above all in therapeutic results. The correct use of the conservative approach, particularly in the immediately post-traumatic phases, the increasingly wide-spread use of endovascular exclusion (T-EVAR), even if not without numerous technical difficulties, and the further improvement of open surgery, currently make it possible to guarantee the individual patient the treatment that can offer the best probabilities of success, at least immediately. Final development, and a more complete and rigorous assessment of the medium and long term results of TEVAR will allow the formulation of therapeutic strategies that are even better defined and increasingly simple to implement, on the basis of algorithms, such as the one proposed by the Authors.
