RESUMO

OBJECTIVE: The pre-treatment presence of at least six efferent patent vessels (EPV) from the AAA sac and/or AAA thrombus volume ratio (VR%) <40% are considered to be positive predictive factors for persistent type II endoleak (ELIIp). The aim of the present study was to evaluate the effectiveness of sac embolization during EVAR in patients with pre-operative morphological risk factors (p-MRF) for ELIIp. METHODS: Patients undergoing EVAR and intra-procedural AAA sac embolization (Group A, 2012-2013) were retrospectively selected and compared with a control group of patients with the same p-MRF, who underwent EVAR without intra-procedural sac embolization (Group B, 2008-2010). The presence of ELIIp was evaluated by duplex ultrasound at 0 and 6 months, and by contrast enhanced ultrasound at 12 months. The association between AAA diameter, age, COPD, smoking, anticoagulant therapy, and AAA sac embolization with ELIIp was evaluated using multiple logistic regression. The primary endpoint was the effectiveness of the intra-procedural AAA sac embolization for ELIIp prevention. Secondary endpoints were AAA sac evolution and freedom from ELIIp and embolization related re-interventions at 6-12 months. RESULTS: Seventy patients were analyzed: 26 Group A and 44 Group B; the groups were homogeneous for clinical/morphological characteristics. In Group A the median number of coils positioned in AAA sac was 4.1 (IQR 1). There were no complications related to the embolization procedures. A significantly lower number of ELIIp was detected in Group A than in Group B (8/26 vs. 33/44, respectively, p < .001) at discharge, and this was confirmed at 6-12 months (7/26 vs. 30/44 respectively, p = .001, and 5/25 vs. 32/44, respectively, p < .001). On multivariate analysis, intra-procedural AAA sac embolization was the only factor independently associated with freedom from ELIIp at 6 (OR 0.196, 95% CI 0.06-0.63; p = .007) and 12 months (OR 0.098, 95% CI 0.02-0.35; p < .001). No differences in median AAA sac diameter shrinkage were detected between the two groups at 6-12 months (p = .42 and p = .58, respectively). Freedom from ELIIp related and embolization related re-interventions was 100% in both groups, at 6 and 12 months. CONCLUSION: Selective intra-procedural AAA sac embolization in patients with p-MRF is safe and could be an effective method to reduce ELIIp. Further studies are mandatory to support these results at long-term follow up.

RESUMO

Huntington's disease was the first adult onset neurological disease for which presymptomatic genetic testing became possible. It served as a model for the approach which constituted a radical change in medical practice and provided an important framework for multi-step, multidisciplinary, counselling for at risk persons. We will review the historical context of guidelines and good clinical practices, the experiences of our team which covers more than 20 years of presymptomatic testing for Huntington's disease in France, and explore the impact of the new French legislation for the future of presymptomatic testing of diseases for which neither preventive measures nor curative treatments are yet available.

RESUMO

OBJECTIVES: Hepatocyte growth factor (HGF), the c-Met receptor, and hypoxia-inducible factor (HIF) are crucial for regenerative processes including ischemic wound healing. The aims of the present study are (a) to analyze the tissue c-Met and HIF-1α expression in skin from patients with critical limb ischemia (CLI); (b) to compare the serum HGF levels of CLI and control subjects. METHODS: This is a prospective, controlled, single-center study. Thirty-seven patients were enrolled. A skin sample adjacent to the ischemic lesion was taken from 20 patients with CLI; skin samples were taken from the surgical wounds of 17 patients surgically treated for abdominal aortic aneurysm as healthy controls. Serum samples were taken in all cases. Samples were formalin fixed, paraffin embedded, and routinely processed. Tissue inflammation was histologically assessed. Immunohistochemistry was performed with antibodies against total c-Met receptor, activated Met (p-Met), and HIF-1α. RT-polymerase chain reaction was used to quantify HIF-1α mRNA. The enzyme-linked immunosorbent assay was performed to evaluate serum HGF levels. RESULTS: With immunohistochemistry, while total c-Met was unchanged, different patterns of p-Met positivity were observed between CLI and control cases (p < .001). In particular, CLI skin showed a total negativity or membrane positivity for p-Met (19/20 cases), while control skin mainly showed cytoplasmic positivity in the epidermal basal layer (16/17 cases). HIF-1α was diffusely lost in CLI, but HIF-1α mRNA was threefold higher than in controls. Finally, mean serum HGF levels were 590.5 pg/mL and 2380.0 pg/mL in CLI and control groups respectively (p < .001). CONCLUSIONS: In CLI patients a significant decrease in serum HGF levels, concomitant with a loss of skin HIF-1α stabilization and a lack of c-Met phosphorylation were seen, probably driving a decrease in wound-healing functions. The next hypothesis is that HGF application might reactivate the c-Met receptor, stabilizing the normal wound healing process.

RESUMO

OBJECTIVE: To evaluate four-dimensional contrast-enhanced ultrasound (4D-CEUS) as an alternative imaging method to computed tomography angiography (CTA) during follow up of fenestrated endovascular aneurysm repair (FEVAR) for juxta- and para-renal abdominal aortic aneurysms (AAA). METHODS: Between October 2011 and March 2012, all consecutive patients who underwent FEVAR follow up were included in the study and evaluated with both 4D-CEUS and CTA. The interval between the two examinations was always ≤ 30 days. Endpoints were the comparison of postoperative AAA diameter, AAA volume, presence of endoleaks, revascularized visceral vessel (RVV) visualization, and patency. Comparative analysis was performed using Bland-Altman plots and McNemar's Chi-square test. RESULTS: Twenty-two patients (96% male, 4% female; mean age 74 ± 7 years; American Society of Anesthesiologists grade III/IV 82%/18%) were enrolled. Seventy-eight RVV (fenestrations: 60; scallops: 17; branches: 1) were analyzed. The mean AAA diameter evaluated by 4D-CEUS and CTA was 45 ± 10 mm (range 30-69 mm) and 48 ± 9 mm (range 32-70 mm), respectively. The mean difference was 3 ± 3 mm. The mean AAA volume evaluated by 4D-CEUS and CTA was 150 ± 7 cc (range 88-300 cc) and 159 ± 68 cc (range 80-310 cc), respectively. The mean difference was 7 ± 4 cc; a Bland-Altman plot revealed agreement in AAA diameter and volume evaluation (p < .01) between 4D-CEUS and CTA. The observed agreement for the detection of endoleaks was 95%. McNemar's Chi-square test confirmed that 4D-CEUS and CTA were equivalent (p > .05) at detecting endoleaks. The first segment of six (8%) RVVs (four renal and two superior mesenteric arteries) was not directly visualized by 4D-CEUS owing to obesity, but the contrast enhancement into the distal part of vessel or into the relative parenchyma gave indirect information about their patency. McNemar's Chi-square test demonstrated the superiority of CTA (p = .031) in visualizing RVVs. The patency of 77/78 RVVs was confirmed with both techniques. McNemar's Chi-square test confirmed that 4D-CEUS and CTA were equivalent in their ability to detect visceral vessel patency. CONCLUSIONS: The data suggest that 4D-CEUS is as accurate as CTA in the evaluation of postoperative AAA diameter and volume, endoleak detection, and RVV patency after FEVAR. Four-dimensional CEUS could provide hemodynamic information regarding RVVs, and reduce radiation exposure and renal impairment during follow up. Obesity limits the diagnostic accuracy of 4D-CEUS.

RESUMO

Diabetic foot (DF) is a chronic and highly disabling complication of diabetes. The prevalence of peripheral arterial disease (PAD) is high in diabetic patients and, associated or not with peripheral neuropathy (PN), can be found in 50% of cases of DF. It is worth pointing out that the number of major amputations in diabetic patients is still very high. Many PAD diabetic patients are not revascularised due to lack of technical expertise or, even worse, negative beliefs because of poor experience. This despite the progress obtained in the techniques of distal revascularisation that nowadays allow to reopen distal arteries of the leg and foot. Italy has one of the lowest prevalence rates of major amputations in Europe, and has a long tradition in the field of limb salvage by means of an aggressive approach in debridement, antibiotic therapy and distal revascularisation. Therefore, we believe it is appropriate to produce a consensus document concerning the treatment of PAD and limb salvage in diabetic patients, based on the Italian experience in this field, to share with the scientific community.

RESUMO

OBJECTIVE/BACKGROUND: The influence of contralateral carotid occlusion (CCO) on the outcome of carotid endarterectomy (CEA) and stenting (CAS) is debated. This study aims to evaluate CEA and CAS results in patients with CCO. METHODS: All carotid revascularizations from 2005 to 2011 were analyzed, focusing on the role of CCO on 30-day cerebral events and death (CED). A meta-analysis was performed to evaluate the results of the literature by random effect. RESULTS: Of the 1,218 carotid revascularizations performed in our institution, 706 (57.9%) were CEA and 512 (42.1%) were CAS. CED occurred in 3.6% of the CEAs and 8.2% of the CASs (p = .001). CCO was present in 37 (5.2%) CEAs and 38 (7.4%) CASs. In CEA, CCO patients had a higher CED compared with the non-CCO patients (16.2% vs. 2.9%, p = .001), as confirmed by multiple regression analysis (OR [odds ratio]: 5.1[1.7-14.5]). In CAS, CED was not significantly different in the CCO and non-CCO patients (2.6% vs. 8.7%, p = 0.23). The comparative analysis of the CCO patients showed a higher CED in CEA compared with that in CAS (16.2% vs. 2.6%, p = 0.04). Meta-analysis of 33 papers (27 on CEA and 6 on CAS) revealed that CCO was associated with a higher CED in CEA, but not in CAS (OR: 1.82 [1.57-2.11]; OR: 1.22 [0.60-2.49], respectively). CONCLUSION: CCO can be considered as a risk factor for CED in CEA, but not in CAS. CAS appears to be associated with lower CED than CEA in CCO patients.

RESUMO

AIM: This study aimed to gain a better understanding of the psychological impact of participating in a clinical trial for patients with Pompe disease (Acid Maltase Deficiency). Attitudes and expectations of adult patients with neuromuscular diseases regarding medical trials are as yet unreported. In order to learn about the psychological consequences of participating in a clinical trial, we conducted a prospective assessment of patients with late-onset Pompe Disease, a rare genetic condition, for which no treatment had been available before. This psychological study was carried out as an ancillary study to the randomized double-blind placebo-controlled trial described elsewhere (van der Ploeg et al., 2010). SUBJECTS AND METHODS: We assessed patients (n=8) at inclusion, and at 12 and 18 months for six psychological dimensions: depression (Beck Depression Inventory, BDI), hopelessness (Beck Hopelessness Scale, BHS), anxiety (STAI A-B), quality of life (Whoqol-26), social adjustment (S.A.S-self-report) and locus of control (IPC Levenson). We produced a self-administered questionnaire in order to assess the attitudes, motivations and expectations of patients during the trial. RESULTS: At 12 months, mean social adjustment (SAS-SR, P=0.02) had improved, and at 18 months mean depression score had improved as well (BDI, P=0.03). The quality of life of patients (Whoqol-26) remained unchanged. Throughout the study, patients were more likely to have an internal locus of control than an external one (IPC Levenson). The self-administered questionnaire showed that patients' expectations were disproportionate compared to the medical information they had received starting the trial. For all patients, the first motivation for being enrolled in a clinical trial was "to help research", for half of them the motivation was to "improve their health". Whether patients believed to be part of one group or another (placebo or treatment) depended on their subjective perception of improvement during the trial. CONCLUSION: Given the small sample size, the conclusions of this study are preliminary. However, findings do suggest that there is a positive psychological impact of participating in a treatment trial. Moreover, the patients' reactions upon unblinding have led us to recommend that patients be asked whether they would like their group assignation disclosed to them or not.

RESUMO

Aim: Early/follow-up durability of superior mesenteric artery (SMA) stent-grafts is crucial after fenestrated/branched endografting (FB-EVAR) in complex abdominal aortic aneurysms (CAAAs) and thoracoabdominal aortic aneurysms (TAAAs). The study aimed to report early/midterm outcomes of SMA incorporated during FB-EVAR procedures. Methods: FB-EVAR procedures performed between 2016 and 2021 in a single institution were reviewed. Anatomical SMA characteristics were analyzed. The SMA configuration was classified into three types according to the angle between the SMA main trunk and the aorta: (A) perpendicular, (B) downward, and (C) upward. SMA-related technical success (SMA-TS: cannulation and stenting, patency at completion angiography without endoleak, stenosis/kinking, dissection, bleeding, and 24-h mortality) and SMA-adverse events (SMA-AEs: one among bowel ischemia, stenosis, occlusion, endoleak, reinterventions, or SMA-related mortality) were assessed. Results: Two hundred FB-EVAR procedures with SMA as the target artery were performed. The indication for FB-EVAR was CAAAs and TAAAs in 99 (49%) and 101 (51%) cases, respectively. The SMA configuration was A, B, and C in 132 (66%), 63 (31%), and 5 (3%) cases, respectively. SMA was incorporated with fenestrations and branches in 131 (66%) and 69 (34%) cases, respectively. Directional branch (P < .001), aortic diameter ≥35 mm at the SMA level (P < .001), and ≥2 SMA bridging stent-grafts (P = .001) were more frequent in TAAAs. Relining of the SMA stent-graft with a bare metal stent was necessary in 41 (21%) cases to correct an acute angle between the stent-graft and native artery (39), stent-graft stenosis (1), or SMA dissection (1). Relining was associated with type A or C SMA configuration (OR: 17; 95% CI: 1.8-157.3; P = .01). SMA-TS was achieved in all cases. Overall, 15 (7.5%) patients had SMA-AEs [early: 9 (60%), follow-up: 6 (40%)] due to stenosis (2), endoleak (8), and bowel ischemia (5). Aortic diameter ≥35 mm at the SMA level was an independent risk factor for SMA-AEs (OR: 4; 95% CI: 1.4-13.8; P = .01). Fourteen (7%) patients died during hospitalization with 10 (5%) events within the 30-postoperative day. Emergency cases (OR: 33; 95% CI: 5.7-191.3; P = .001), peripheral arterial occlusive disease (OR: 14; 95% CI: 2.3-88.8; P = .004), and bowel ischemia (OR: 41; 95% CI: 1.9-87.9; P = .01) were risk factors for 30-day/in-hospital mortality. The mean follow-up was 32 ± 24 months; estimated 3-year survival was 81%, with no case of late SMA-related mortality or occlusion. The estimated 3-year freedom from overall and SMA-related reinterventions was 74% and 95%, respectively. Conclusion: SMA orientation determines the necessity of stent-graft relining. Aortic diameter ≥35 mm at the SMA level is a predictor of SMA-AEs. Nevertheless, SMA-related outcomes of FB-EVAR are satisfactory, with excellent technical success and promising clinical outcomes during the follow-up.

RESUMO

OBJECTIVES: Enzymatic pancreatic injury (EPI) in abdominal aortic aneurysm (AAA) treatment has been scarcely studied in the literature. Aim of this work was to compare perioperative EPI in AAA patients treated by endovascular repair (EVAR) or open repair (OR). METHODS: Forty AAA patients consecutively treated with either EVAR (GI, 20 pts) or OR (GII, 20 pts) were prospectively evaluated in terms of epidemiology, comorbidities and technical details. Serum levels of amylase, lipase and pancreatic isoamylase were assessed before treatment (T0), before aortic clamping/endograft deployment (T1), 1, 2, and 6 hours after aortic declamping/endograft deployment (T2, T3, T4) and 24, 48, and 72 hours after the procedure (T5, T6, T7). GI and GII were compared by Mann Whitney test with significance set at p < 0.05. RESULTS: GI patients were significantly older and with higher frequency of preoperative renal insufficiency than GII ones (p = 0.001 and 0.047 respectively). Other characteristics were not significantly different. Pancreatic enzymes values at T0 were within normal parameters in all patients. Total serum amylase was significantly greater at T4 (p = 0.003), T5 (p = 0.010), T6 (p = 0.003), T7 (p = 0.011) and isoamylase at T3 (p = 0.052), T4 (p = 0.037), T5 (p = 0.016) and T6 (p = 0.014) in GII compared with GI. Amylase and isoamylase peak occurred 24 hours after the procedure. Lipase was significantly different in the two groups only in T4 (p = 0.028). No acute pancreatitis occurred in the whole study group. CONCLUSIONS: EVAR significantly reduces EPI compared with OR in the AAA treatment.

RESUMO

AIM OF THE STUDY: In this study, we propose to use a thermal technique, Differential Scanning Calorimetry (DSC) to follow the evolution of elastin and collagen in safe and pathological cardiovascular tissues. PATIENTS AND METHODS: The first part of this study deals with the analysis of the elastin network and associated proteins during ageing (from children to old persons) in aortic walls. The second part is devoted to the characterization of the collagenic phase in aneurysms. In both cases, physical data are correlated with biochemical analyses. RESULTS AND CONCLUSION: For old persons aortas with atheromatous stades, elastin and associated proteins are found to interpenetrate to form a homogenous phase. Abdominal aortic aneurysms (AAA) are characterized by structural alterations of the aortic wall resulting from the degradation of elastic fibers and an increase of collagen/elastin ratio. Notable modifications are evidenced between collagen from control tissue and collagen from AAA, particularly concerning the thermal denaturation. Biochemical and thermal results are compatible with the increase of new collagen deposition and/or impairment of the collagen phase stability in the extracellular matrix of AAAs.

RESUMO

Huntington disease is a neurodegenerative disorder transmitted as an autosomal dominant trait. It is the first neurological disease for which presymptomatic testing has been available for 20years in France. Follow-up of mutation carriers provided a better understanding of the presymptomatic phase of the disease and will change medical practice. Studying this phase led to the identification of clinical, imaging and plasma markers prior to motor onset, which will allow finding the optimal window for preventive treatment and follow-up of its efficacy.

RESUMO

The tolerance of exercise and its effects on quality of life in myasthenia gravis are not currently backed up by strong evidence. The aim of this study was to determine whether exercise as an adjunct therapy is well tolerated and can improve health-related quality of life (HRQoL) in stabilized, generalized autoimmune myasthenia gravis (gMG). We conducted a parallel-group, multi-center prospective RCT using computer-generated block randomization. Adults with stabilized, gMG, and no contra-indication to exercise, were eligible. Participants received usual care alone or usual care and exercise. The exercise intervention consisted of 3-weekly 40 min sessions of an unsupervised, moderate-intensity home rowing program over 3 months. The primary endpoint was the change in HRQoL from randomization to post-intervention. Assessor-blinded secondary endpoints were exercise tolerance and effects on clinical, psychological and immunological status. Of 138 patients screened between October 2014 and July 2017, 45 were randomly assigned to exercise (n = 23) or usual care (n = 20). Although exercise was well tolerated, the intention-to-treat analysis revealed no evidence of improved HRQoL compared to usual care (MGQOL-15-F; mean adjusted between-groups difference of -0.8 points, 95%CI -5.4 to 3.7). Two patients hospitalized for MG exacerbation were from the usual care group.

RESUMO

OBJECTIVES: To compare the effectiveness of oral slow-release oxycodone (group OX, n=18) with that of epidural l-bupivacaine (group LRA, n=13) for the control of moderate/severe pain of advanced-stage peripheral arterial obstructive disease (PAOD) patients. DESIGN: Observational and retrospective analysis of advanced stage and hospitalised PAOD patients treated for pain management for at least 7 days prior to surgery or discharged from the hospital without surgery. METHODS: The outcome measures were pain intensity using the visual analogue scale under static, (VASs) and dynamic (VASd) conditions; vital signs, treatment side effects and patient satisfaction. RESULTS: In both groups, pain control was satisfactory and VAS scores median were VASs<3 and VASd<4; under dynamic conditions, pain control was better in the LRA group (p<0.01). Against few and transient side effects, most patients (n=30) found both pain treatments good or excellent. Results should be confirmed by studies with larger samples. CONCLUSIONS: In the perioperative setting, the epidural infusion of local anaesthetics, such as l-bupivacaine, is an effective technique for pain control in PAOD patients; for patients with contraindication for this technique or for non-surgical or outpatients, slow-release oxycodone is suggested as a possible alternative for the control of severe pain in these patients.

OBJECTIVES AND DESIGN: To establish whether in diabetic patients with peripheral artery obstructive disease (PAOD) vasa vasorum (vv) neoangiogenesis is altered with increased arterial damage. MATERIALS: Thirty-three patients with PAOD and critical lower limb ischaemia, 22 with type II diabetes. METHODS: Immunohistochemistry for endothelial cell markers (CD34 and von Willebrand Factor); real-time reverse transcription polymerase chain reaction (RT-PCR) to quantify arterial wall expression of vascular endothelial growth factor (VEGF); enzyme-linked immunosorbent assay (ELISA) to assess blood VEGF; flow cytometry to detect circulating endothelial cells (CECs). RESULTS: Patients with PAOD and diabetes have a higher frequency (60% vs. 45%) of advanced atherosclerotic lesions and a significant reduction (p = 0.0003) in CD34(+) capillaries in the arterial media. Adventitial neoangiogenesis was increased equally (CD34(+) and vWF(+)) in all patients. Likewise, all patients have increased CEC and VEGF concentration in the blood as well as in-situ VEGF transcript expression. CONCLUSIONS: Patients with PAOD have remarkable arterial damage despite increased in-situ and circulating expression of the pro-angiogenic VEGF; a dysfunctional vv angiogenesis was seen in diabetics which also showed a higher frequency of parietal damage; it is suggested that in diabetic arterial wall, injury is worsened by vv inability to finalise an effective VEGF-driven arterial wall neoangiogenesis.

RESUMO

AIM: Abdominal aortic aneurysms (AAA) with severe angulation of the neck or of the iliac arteries are often unsuitable for endovascular repair with conventional endografts. We evaluated the performance of a ring-stent abdominal endograft (AnacondaTM Vascutek, Terumo, Scotland) in a consecutive series of infrarenal AAA. METHODS: Preoperative, procedural and follow-up data of patients treated with AnacondaTM endograft between September 2005 and September 2009 were prospectively enrolled. Patients were divided in Group A (proximal neck angle > or =60 degrees or iliac arteries angle > or =90 degrees ) and Group B (all others). Main endpoints were technical and clinical success (primary and assisted) and late outcome in the two groups. Results were compared by Kaplan-Meier life table analysis with log-rank test (Mantel-Cox). RESULTS: One hundred twenty-seven patients, with a mean age of 73.5+/-6.9 years, have been included in this series. Mean aneurysm size was 56.7+/-10.4 mm. A severe angulation of the proximal aortic neck or/and of the iliac arteries was present in 44 cases (Group A), absent in 83 cases (Group B). The mean follow-up was 18.2+/-16.3 months. Overall primary technical success was achieved in 100% of the patients. At twenty-four months survival, primary and assisted clinical success were 94.2%, 88.2% and 91.3% in Group A and 80.3%, 83.7% and 95.2% in Group B respectively. No significant differences were found between the two groups. The only factor significantly associated with decreased survival was preoperative renal insufficiency. Iliac limb patency 24 months after EVAR in severely and non-severely angulated iliac axis was 96.7% and 98.1% respectively, with no significant difference between the groups. Only one proximal type I endoleak was detected in a patient with severe angulation of proximal aortic neck. No significant correlation between proximal type I endoleak and severe neck angulation was found. CONCLUSION: Aneurysms with severe neck or iliac arteries angulation can be treated by a ring-stent endograft with results similar to those of AAA with more favourable anatomy.

RESUMO

Cryptococcus neoformans CNS infection frequently affects HIV-infected patients and is often lethal, despite antifungal therapy. The most recent treatment guidelines for Cryptococcal meningitis recommend therapy with lyposomal amphotericin B and possible association with flucitosine. However, clinical response rates in HIV-infected patients are not satisfactory, with a persistent high mortality rate and long term therapy is affected by a high risk of major side effects. Posaconazole, the latest broad-spectrum azole, with both in vitro- and in vivo-documented potent activity against C. neoformans, clearly showed no antagonism with amphotericin B, echinocandins or flucytosine and it has both in vitro and in vivo agonistic activity with flucytosine against C. neoformans. We report two cases of successful salvage therapy based on the addition of posaconazole to a standard treatment based on liposomal amphotericin B and Flucytosine. In addition we used posaconazole also in a maintenance therapeutic regimen with no evidence of recurrences in the follow up of these patients. Our report confirms that posaconazole has clinical activity in the CNS against C. neoformans infection. In addition posaconazole showed no antagonism with any other currently available antifungal agent, and was in fact synergistic to some of them (flucytosine); consequently, it seems to be an ideal candidate for antimicrobial combination salvage therapies. Finally posaconazole represents a good alternative to parenteral therapy and an ideal candidate for long-term maintenance therapy due to its competent toxicity profile and oral bioavailability.

RESUMO

AIM: The Anaconda endograft (Vascutek, Terumo, Inchinnan, Scotland) is an infrarenal, trimodular stent-graft with peculiar characteristics in terms of implant, proximal sealing and fixation of the main body and iliac legs. This endograft can be used in infrarenal abdominal aortic aneurysm (AAA) with an aortic neck >or=15 mm in length. The authors evaluated the mid-term outcome of the Anaconda endograft in the treatment of infrarenal AAA also in cases with tortuous anatomy. METHODS: Between September 2005 and September 2008, 100 patients (94 males, 6 females) with mean age of 73.9+/-5.2 years (range 55-89) were considered eligible for treatment with Anaconda endograft (proximal neck length >or=15 mm). The mean aneurysm size was 55.2+/-3.4mm (range 45-99 mm). An angulation of the aortic neck greater than 60 degrees was present in 19 cases. The iliac arteries were severely angulated >60 degrees in 61 patients. The mean follow-up was 23.2+/-11.0 months (range 1.4-38.6). RESULTS: Primary technical success was achieved in 100% of the patients. Six patients died during follow-up, none for aneurysm-related causes. Survival rate was 87.9% at 24 months of follow-up. Primary and assisted clinical success were respectively 80.8% and 93.7% at 24 months with a freedom from reintervention of 88.8%. No cases of endograft migration were observed and only one case of type I proximal endoleak was recorded in the mid-term follow-up. The univariate and the multivariate analysis did not show an increased risk in patients with angulated proximal neck or iliac arteries. CONCLUSIONS: As evidenced in this clinical study, the mid-term outcomes of Anaconda endograft are satisfactory concerning the treatment of AAA with a minimum neck length of 15 mm. This device proved in the mid-term to effectively protect the patient treated from aneurysm rupture. Presence of even severe tortuosity of the proximal neck and of the iliac arteries did not affect outcomes. Considering these results showing the safety of Anaconda endograft, the authors suggest its employment also in cases with difficult anatomy.

RESUMO

OBJECTIVE: This article deals with the attempt to join HIV and geriatric care management in the 2017 edition of the Italian guidelines for the use of antiretrovirals and the diagnostic-clinical management of HIV-1 infected persons. METHODS: The outlined recommendations are based on evidence from randomized clinical trials and observational studies published in peer-reviewed journals and/or presented at international scientific conferences in recent years. The principles of starting antiretroviral therapy in elderly patients and the viro-immunological goals are the same as in the general HIV population. However, there are some specificities to consider, related to the host as well as the therapy itself. HIV care in elderly patients must shift from a combined AntiRetroviral Therapy specific approach to a more comprehensive management, and from a disease-based model (list of co-morbidities) to a multi-morbidity and frailty standpoint. The implementation of a geriatric approach, based on the Comprehensive Geriatric Assessment, is essential and consists of a broader evaluation of health status. This multidimensional and multidisciplinary evaluation is focused on the development of a tailored intervention plan. Polypharmacy is a frequent condition in the older population and an independent risk factor for negative health-related outcomes. This can be overcome with a multidisciplinary and cooperative approach involving HIV specialists, geriatricians and primary care physicians. CONCLUSION: The inclusion of geriatric care becomes necessary due to the novel needs of an evolving patient population. It is important to underline that the HIV specialist will continue to lead multidimensional interventions and optimize quality of care for HIV-positive people.
