Abstract
Abstract
Background
Low-flow low-gradient (LF-LG) aortic stenosis (AS) may occur with preserved or depressed left ventricular ejection fraction (EF), and both situations represent the most challenging subset of patients with AS to manage and generally have a poor prognosis with conservative therapy but a high operative mortality if treated surgically. Few and controversial data exist on the outcomes of these patients compared to normal-flow high-gradient (NF-HG) AS following transcatheter aortic valve replacement (TAVR).
Purpose
This study aims to better characterize patients with different transvalvular flow-gradient patterns undergoing TAVR and to examine the prognostic value of these flow state.
Methods
Overall, 1208 patients with severe symptomatic AS undergoing TAVR were categorized according to flow-gradient patterns as follow: 976 patients NF-HG (DPmean >40 mmHg), 107 paradoxical LF-LG (pLF-LG: DP mean <40 mmHg, EF >50%, and SVi <35 mL/m2), and 125 classical LF-LG (DP mean <40 mmHg, EF <50%, SVi <35 mL/m2).
Results
TAVR was feasible in all AS subtypes. When compared with NF-HG and pLF-LG, LF-LG had a worse symptomatic status (NYHA III–IV 86% vs 62% and 67%, respectively, p<0.001), a higher prevalence of eccentric hypertrophy (Figure 1, left), a higher level of LV global afterload reflected by a higher valvuloarterial impedance and a higher pulmonary pressure (Table). Valvular function after TAVR was excellent over time with respect to aortic pressure gradient (mean and peak) and aortic valve area regardless of flow state group. While intraoperative (p=0.935) and 30-day mortality (p=0.911) did not differ significantly among the 3 groups, LF-LG had a lower overall 5-year survival (LF-LG 50%, pLF-LG 65%, NF-HG 84%, p<0.001) (Figure 1, right). LF-LG AS was associated with a hazard ratio for 5-year mortality of 2.416 (95% CI: 1.658–3.520, p<0.001).
Conclusions
TAVR is an effective procedure in all patients with severe AS regardless of transvalvular flow-gradient patterns. However, special care should be given to characterized hemodynamic of AS, as patients with pLF-LG had similar survival rate than patients with NF-HG, whereas survival in LF-LG patients was 2-fold higher. Therefore, being able to identify patients less likely to improve after TAVR may help to guide treatment decision.

Abstract
Abstract
Aims
Haemodynamic classifications of severe aortic stenosis (AS) have important prognostic implications, with low flow state (defined on the basis of a stroke volume index, SVi<35 mL/m2) known to be a predictor of worse prognosis. As transcatheter aortic valve replacement (TAVR) has become widely used for patients with severe AS, issues were raised concerning its efficacy in patients with different haemodynamic classifications combining transvalvular flow state and pressure gradients. In fact, data on TAVR outcomes in patients with low gradient (LG) AS are limited and in some cases controversial. The aim of this study was to evaluate the efficacy and long-term clinical and echocardiographic outcome of TAVR in patients with different transvalvular flow-gradient patterns.
Methods
In this single centre study, 1078 patients (mean age 81±7 years) with severe symptomatic AS (AVA<1 cm2) undergoing TAVR were categorized according to flow-gradient patterns as follow: 867 patients (80%) with normal flow-high gradient (NF-HG: mean transaortic gradient DP mean>40 mmHg), 94 (9%) with paradoxical low flow LG (pLF-LG: DP mean<40 mmHg, ejection fraction EF > 50%, and SVi<35 mL/m2), and 117 (11%) classical LF-LG (DP mean<40 mmHg, EF < 50%, SVi<35 mL/m2).
Results
TAVR was feasible in all AS subtypes with similar rate of unsuccessful procedure (1.3% NF-HG, 1.1% pLF-LG, 0% LF-LG P=470). Valvular function after TAVR was excellent over time with respect to aortic pressure gradient (mean and peak) and aortic valve area regardless of flow state group (Figure A). Overall, intraoperative (P=957) and 30-day mortality (P=817) did not differ significantly among the 3 groups. Longer follow-up showed that, compared to NF-HG patients, pLF-LG had similar all-cause mortality rate [HR 1.35(0.95–1.90), P=0.094] up to 5 years and LF-LG had a significant higher mortality rate [HR 1.89(1.43–2.49), P<0.001],(Figure B). Moreover, LF-LG patients had higher rehospitalization for heart failure (NF-HG: 3%, pLF-LG: 6%, LF-LG 10%, P=0.001).
Conclusions
We provided evidence that TAVR is an effective procedure in all patients with severe AS regardless of transvalvular flow-gradient patterns. A careful haemodynamic classifications of severe AS is of utmost importance for identifying patients who benefits the most from TAVR procedure.

Aortic Valve Sclerosis as an Important Predictor of Long-Term Mortality in Patients With Carotid Atheromatous Plaque Requiring Carotid Endarterectomy. Front Cardiovasc Med 2021; 8:653991. [PMID: 34124193 PMCID: PMC8193358 DOI: 10.3389/fcvm.2021.653991] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Accepted: 04/26/2021] [Indexed: 12/27/2022] Open
Abstract
Background: A strong association between aortic valve sclerosis (AVSc), the earliest manifestation of calcific aortic valve disease, and atherosclerosis exists. The aim of the study was to evaluate the predictive capabilities of AVSc on long-term all-cause mortality, in patients requiring carotid endarterectomy (CEA). Methods and Results: 806 consecutive CEA patients were enrolled. Preoperative echocardiography was used to assess AVSc. Computed tomography angiography was applied for plaque characterization. Kaplan-Meier curves, Cox linear regression, and area under the receiving operator characteristic (AUC) curve analyses were used to evaluate the predictive capability of AVSc. Overall, 348 of 541 patients had AVSc (64%). Age, diabetes, and estimated glomerular filtration rate (eGFR) were associated with AVSc. In the 5-year follow-up, AVSc group had a mortality rate of 16.7% while in no-AVSc group was 7.8%. Independent predictors of all-cause mortality were age, sex, eGFR, left ventricular ejection fraction, and AVSc. After adjustments, AVSc was associated with a significant increase in all-cause mortality risk (hazard ratio, HR = 1.9; 95%CI: 1.04–3.54; p = 0.038). We stratify our cohort based on carotid atheromatous plaque-type: soft, calcified, and mixed-fibrotic. In patients with mixed-fibrotic plaques, the mortality rate of AVSc patients was 15.5% compared to 2.4% in no-AVSc patients. In this group, AVSc was associated with an increased long-term all-cause mortality risk with an adjusted HR of 12.8 (95%CI: 1.71–96.35; p = 0.013), and the AUC, combing eGFR and AVSc was 0.77 (p < 0.001). Conclusions: Our findings indicate that AVSc together with eGFR may be used to improve long-term risk stratification of patients undergoing CEA surgery.

Proper Selection Does Make the Difference: A Propensity-Matched Analysis of Percutaneous and Surgical Cut-Down Transfemoral TAVR. J Clin Med 2021; 10:jcm10050909. [PMID: 33669044 PMCID: PMC7956334 DOI: 10.3390/jcm10050909] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Revised: 02/17/2021] [Accepted: 02/18/2021] [Indexed: 11/22/2022] Open
Abstract
Background. Transcatheter aortic valve replacement (TAVR) is an established technique to treat severe symptomatic aortic stenosis patients with a wide range of surgical risk. Currently, the common femoral artery is the first choice as the main access route for the procedure. The objective of this observational study is to report our experience on percutaneous and surgical cut-down transfemoral TAVRs comparing the two approaches. Methods. From January 2014 to January 2019, five hundred eleven consecutive patients underwent TAVR for severe symptomatic aortic stenosis. We analyzed only elective transfemoral procedures. After propensity score-matching based on age, sex, EuroSCORE II, mean aortic gradient, and left ventricular ejection fraction, we obtained two homogeneous populations: surgical cut-down (n = 119) and percutaneous (n = 225), which were labeled Group 1 and Group 2, respectively. Results. The main findings were that there were no significant procedural outcome differences between the two groups, but Group 2 patients had a shorter length of hospital stay and were more frequently discharged home. At follow-up, Group 1 patients had lower survival rates. Conclusions. An accurate preoperative assessment of the femoral access is mandatory to achieve satisfactory outcomes with transfemoral TAVRs. Nevertheless, the percutaneous approach allows shorter in-hospital stay and the need for rehabilitation, thus potentially decreasing the costs of the procedure.

Background. Transcatheter aortic valve-in-valve (TAVI ViV) implantation is an appealing treatment option for patients with degenerated bioprostheses. However, elevated residual gradients after TAVI ViV procedure are very common. These are an unwanted effects of prosthesis-patient mismatch (PPM). Currently, the actual incidenceof PPM, its predictors and its clinical outcomes have not been completely investigated.
Purpose. The aims of this study was to investigate the incidence, predictors and clinical outcome of PPM and therefore of elevated gradients after TAVI ViV.
Methods. 75 patients (age 78 ± 9 years, 36 male), who underwent TAVI-ViV due to failed aortic biological valve (60 stented, 15 stentless), were enrolled. Mechanism of bioprosthetic valve failure was stenosis (34 cases, 45%), regurgitation (24 cases, 32%) or combination (17 cases, 23%). Elevated residual gradients were defined as a mean DP> 20 mmHg. PPM was identified by the indexed effective orifice area (EOAi) measured by echocardiography (moderate PPM if 0.65 < EOAi < 0.85 cm²/m²; severe PPM if EOAi < 0.6 cm²/m²).
Results. ViV TAVI was feasible in all patients, 33 patients (44%) were implanted with a balloon-expandable valve and 42 (56%) with a self-expandable valve. Post-procedural post-ballooning was performed in 16 out of 42 patients (38%) receiving a self-expandable valve. Post-operative mean DP> 20 mmHg was found in 35 patients (48%). Moderate PPM was found in 24 cases (33%) and severe PPM in 15 (20%). A logistic regression analyses identified small size of surgical prosthesis (size < 23 mm) [OR: 6.061(2.127-17.267), p = 0.001] and failed stented valve [OR: 20.727(2.522-170.364), p = 0.005] as independent predictors for the occurrence PPM. Interestingly PPM did not affect early and 1 years mortality (1 years mortality 1.3 %), while mortality was higher in pts with stentless prostheses (9%)
Conclusions. PPM is a frequent finding after ViV procedures. Despite elevated residual gradients, TAVI ViV resolved prosthetic dysfunction and PPM did not affect mortality. Therefore, this procedure represents a promising new option for patients with failed biological prosthetic valves.

Abstract
Objective During the most aggressive phase of the COVID-19 outbreak in Italy, the Regional Authority of Lombardy identified a number of hospitals, named Hubs, chosen to serve the whole region for highly specialised cases, including vascular surgery. This study reports the experience of the four Hubs for Vascular Surgery in Lombardy and provides a comparison of in hospital mortality and major adverse events (MAEs) according to COVID-19 testing. Methods Data from all patients who were referred to the Vascular Surgery Department of Hubs from 9 March to 28 April 2020 were collected prospectively and analysed. A positive COVID-19 polymerase chain reaction swab test, or symptoms (fever > 37.5 °C, upper respiratory tract symptoms, chest pain, and contact/travel history) associated with interstitial pneumonia on chest computed tomography scan were considered diagnostic of COVID-19 disease. Patient characteristics, operative variables, and in hospital outcomes were compared according to COVID-19 testing. A multivariable model was used to identify independent predictors of in hospital death and MAEs. Results Among 305 included patients, 64 (21%) tested positive for COVID-19 (COVID group) and 241 (79%) did not (non-COVID group). COVID patients presented more frequently with acute limb ischaemia than non-COVID patients (64% vs. 23%; p < .001) and had a significantly higher in hospital mortality (25% vs. 6%; p < .001). Clinical success, MAEs, re-interventions, and pulmonary and renal complications were significantly worse in COVID patients. Independent risk factors for in hospital death were COVID (OR 4.1), medical treatment (OR 7.2), and emergency setting (OR 13.6). COVID (OR 3.4), obesity class V (OR 13.5), and emergency setting (OR 4.0) were independent risk factors for development of MAEs. Conclusion During the COVID-19 pandemic in Lombardy, acute limb ischaemia was the most frequent vascular disease requiring surgical treatment. COVID-19 was associated with a fourfold increased risk of death and a threefold increased risk of major adverse events.

Abstract
Multiple valve replacements are known to carry additional risk of morbidity and mortality in redo context. Currently, a transcatheter-based valve-in-valve approach could be useful in reducing potential serious consequences. On the other hand, this approach poses several technical challenges regarding the device and the procedural aspects. We present the case of a 78-year-old man who presented with symptoms of heart failure due to mitral and aortic bioprosthesis degenerations who was deemed to be at extremely high risk for a conventional redo surgery. A two-step transcatheter-based approach was planned and a transfemoral aortic valve-in-valve procedure was followed by a transapical mitral valve-in-valve implantation with a favorable early and long-term outcome.

Abstract
Abstract
Background
Controversial data exist on clinical outcomes of patients with paradoxical low-flow, low-gradient aortic stenosis (PLF-LG) undergoing valve replacement. This entity is a combination of a small aortic valve area (AVA<1cm2), a preserved left ventricular ejection fraction (LVEF≥50%), and a “paradoxical” low mean gradient due to the presence of low LV stroke volume (≤35 mL/m2). The low flow state is explained by the presence of a high afterload and pronounced LV concentric remodeling, with impaired LV filling. Currently, poorer outcomes have been reported after surgical aortic valve replacement in patients with PLF-LG AS compared with the normal-flow high-gradient (NF-HG) AS.
Purpose
The aim of this study was to determine the clinical outcomes in patients with PLF-LG AS undergoing transcatheter aortic valve implantation (TAVI) compare to NF-HG patients.
Methods
A total of 609 patients (age 81±6 years) with symptomatic severe AS and preserved LVEF who underwent TAVI, was enrolled and divided in two groups: group A included patients with NF-HG (542 patients) and group B including those with PLF-LG (66 patients). At 1-year follow-up, death and clinical events were reported.
Results
TAVI was feasible in all patients. A significant reduction in mean aortic pressure gradient was observed after TAVI both in PLF-LG (baseline, 30±5 mmHg; 1-year, 11±4 mmHg; p<0.001) and in NF-HG (baseline, 53±11 mmHg; 1-year, 12±4 mmHg; p<0.001) together with an increase in AVA (PLF-LG: baseline, 0.74±0.16 cm2, 1-year: 1.83±0.41 cm2, p<0.001; NF-HG: baseline, 0.65±0.16 cm2, 1-year: 1.84±0.35cm2, p<0.001). Perioperative mortality at 30-days was similar in group A (17/542, 3%) and in group B (2/66, 3%). Figure shows the survival curves up to 5 years follow-up according to the two groups. PLF-LG and HG-AS had similar survival rate throughout the long-term follow-up. Similarly, rehospitalization rate was not different in the two groups (PLF-LG: 12% vs NF-HG: 7%, p=0.121).
Kaplan-Meier analysis
Conclusions
Differently from surgical series, TAVI patients with PLF-LG AS had showed similar mortality and rehospitalization rates compared to NF-HG.

Mitral valve regurgitation in patients undergoing TAVI: Impact of severity and etiology on clinical outcome. Int J Cardiol 2019; 299:228-234. [PMID: 31353154 DOI: 10.1016/j.ijcard.2019.07.060] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2018] [Revised: 06/21/2019] [Accepted: 07/17/2019] [Indexed: 01/06/2023]
Abstract
BACKGROUND Mitral regurgitation (MR) is frequently associated with severe aortic stenosis, but its influence on outcomes after transcatheter aortic valve implantation (TAVI) remains controversial. This study sought to assess the baseline etiology and degree of MR in TAVI population, identify the predictors of MR changes and investigate the clinical and prognostic impact of baseline MR at mid and long-term follow-up. METHODS We enrolled 572 consecutive patients who underwent TAVI. MR degree and etiology were evaluated by echocardiography at baseline and 1-year follow-up. Clinical outcomes were obtained up to 3-year follow-up. RESULTS At baseline, 168 patients (29%) had moderate-to-severe MR (MR ≥ 2). Organic MR was more frequently associated with MR ≥ 2 (MR < 2: 20%, MR ≥ 2: 43%, p < 0.001). Relevant MR had improved more in functional MR (79%) compared to organic MR (50%, p = 0.001). At the multivariate analysis, the coexistence of coronary artery disease (p = 0.026), absence of atrial fibrillation (p = 0.038) and functional etiology (p = 0.025) were predictors of MR improvement after TAVI. Patients with baseline MR ≥ 2 had a higher mortality rate than those with MR < 2 at 1-year and 3-year follow-up. Moreover, a landmark analysis starting from 1-year to 3-year follow-up, demonstrated that organic MR was associated with an increased risk of mortality throughout 3-year follow-up compared with functional MR, irrespective of MR severity. CONCLUSIONS Baseline MR ≥ 2 in TAVI patients was associated with early and late mortality rate. At 1-year, significant improvement in MR severity was observed mainly in patients with functional MR ≥ 2. Organic MR ≥ 2 had a negative impact on 3-year, but not 1-year, mortality rate.

Abstract
Background Transcatheter aortic valve replacement (TAVR) is nowadays generally accepted as the treatment of choice for high- to intermediate-risk patients with severe aortic stenosis not suitable for the standard surgical replacement. Many vascular accesses have been described for the valve delivery, comprising the common iliac artery as the arterial site of access. Methods From September 2008 to June 2014, 440 patients underwent TAVR at our institution. We report a series of 12 patients that have undergone TAVR via a trans-iliac (TI) retroperitoneal surgical approach and also discuss its feasibility, security, and medium-term follow-up. Results The 30-day survival rate was 92%. Only 1 local vascular access major complication occurred requiring an iliac-femoral bypass grafting with a vascular graft. Two patients experienced transient neurological ischemic attack. At 3-year follow-up, all the 11 patients were alive and well and the echocardiographic evaluation revealed good function of the prosthesis. Conclusions The TI route seems to be feasible with a low profile of local complications. It may be a reasonable access alternative to the femoral artery and to the trans-apical approach. A broader, prospective study is advisable to gain general consensus on this approach.

Abstract
BACKGROUND To evaluate the early safety and clinical performance of the new low-profile RelayPro Thoracic Stent-Graft System in patients with thoracic aortic disease. METHODS This was an international, prospective, single-arm study in patients diagnosed with thoracic aorta disease (aneurysm, pseudoaneurysm, dissection, penetrating atherosclerotic ulcer, or intramural hematoma) and treated with a RelayPro stent-graft (in bare stent and/or nonbare stent configurations). The primary endpoints were freedom from aneurysm or dissection-related mortality and stent-graft performance. RESULTS A total of 31 patients were treated with the RelayPro thoracic stent-graft between 2014 and 2015 at 8 sites in Italy and Spain. Mean age was 72.1 (±10.2) years and 77% were male, 74% with hypertension, and 42% with a history of smoking. Twenty-four (77%) had aneurysms (fusiform in 46%, saccular in 42%, pseudoaneurysm in 12%); 5 (16%) had penetrating atherosclerotic ulcer; and 2 (6%) had chronic Type B dissection. Mean vascular access diameter was 9.1 mm (6-13 mm); 7 patients (23%) had vascular access of 7 mm or less. Technical success was 100% (primary, 90%; assisted primary, 10%). Freedom from aneurysm/dissection-related mortality through 30 days was 100%. Freedom from device-related major adverse events through 30 days was 94%. At 1 year, there was 1 (3%) type Ib and 1 (3%) type II endoleak, 1 (3%) nonaneurysm-related late death, and 1 (3%) secondary intervention (to correct type Ib endoleak). CONCLUSIONS The RelayPro has a 3-4 French profile reduction to allow endovascular repair of thoracic aortic disease in patients with smaller anatomies. This study shows good initial stent-graft performance and a favorable early safety profile.

Abstract
Aims Scarce data are available on the long-term structural and functional changes of prosthetic valves after transcatheter aortic valve implantation (TAVI). The objective was to evaluate with echocardiography the long-term structural and functional changes of prosthetic valves after TAVI. Methods and results Structural valve deterioration (SVD) was defined as leaflet thickening ≥3mm, presence of calcification and abnormal leaflet motion. Five-year echocardiographic follow-up was available in 96 out of 318 patients who underwent TAVI with a balloon-expandable device between April 2008 and December 2011. At 1-year follow-up, no patient showed SVD. At 5-year follow-up, SVD were observed in 29 (30%) patients who showed also a significant reduction of aortic valve area (AVA) together with an increase of mean and peak aortic pressure gradients at the latest echocardiography evaluation. Moreover, rate of central aortic valve regurgitation ≥2 was higher in SVD patients as compared to those without SVD, while there was no difference in terms of paravalvular regurgitation. Despite SVD, one patient only reached the criteria for severe stenosis and no reintervention was needed at 5-year follow-up. Variables independently associated with SVD were female sex, small body surface area, use of a 23 mm valve, and small AVA at pre-discharge echocardiogram. Conclusion At 5-year follow-up, 30% of patients who underwent TAVI with a balloon-expandable valve showed initial SVD. However, SVD was not associated with severe stenosis in most of the patients and had no significant impact on and clinical outcome.

Abstract
No consensus exists on the timing, safety, and efficacy of treating severe symptomatic aortic and carotid stenosis. In the older population and in the presence of multiple comorbidities that arise during the surgery, a less invasive transcatheter treatment may be the only reasonable option. We discuss this topic by analyzing a case of an 84-year-old man who underwent a combined single-stage transcatheter procedure.

Abstract
Different vascular accesses have been described for the delivery of a transcatheter aortic bioprosthesis. We report the use of the superficial femoral artery (SFA) as the arterial site of puncture with surgical cut-down. It may be a reasonable access alternative to the other classical routes, especially in the setting of either obese patients with elevated body mass index or in the presence of high femoral artery bifurcation. This route seems to be feasible with a low-profile risk.

Abstract
BACKGROUND Prospective single-arm study, aimed at evaluating safety and effectiveness at 12 and 24 months of the paclitaxel-eluting nitinol stent (Zilver PTX), and focused in particular on the treatment of complex lesions and/or diabetic patients. METHODS Between May 2010 and March 2012, 67 patients (78% males) were treated by Zilver PTX, because of stenosis or occlusions of the superficial femoral artery in one of two centers. The mean age of patients was 70.1±8 years. Thirty-two of 67 (48%) were diabetics, 14 (21%) active smokers and 11 (14.6%) had chronic renal failure (end stage renal disease). The average length of lesions was 104±60 mm. Occlusion was complete in 46.3% of cases, whereas severely calcified lesions were present in 30% of patients (18.8% in diabetics and 31.4% in non-diabetics). Twenty-six patients (39%) had type C or D lesions according to TASC 2. RESULTS One hundred-two stents were used (1.7±0.9 per patients); median 1 (range 1-4). All patients had successful stent placement. Primary patency, evaluated by Kaplan-Meier method was 88±0.06% at 12 months, and 68±0.1% at 24 months. In particular, the difference between diabetics (D) and non-diabetics (non-D) was not significant (P=0.07, Log-Rank). Patients turned from 4.2±1.3 to 1.6±1.3 Rutherford class. There were 5 deaths due to systemic comorbidities. There also were 3 major amputations, all of them also in the D group. Among the other patients, differences between D and non-D patients were not significant in terms of wound healing, bipedal stay and spontaneous ambulation. The mean follow-up length was 28±5 months (range 24-36 months). There was only one patient who had fracture and stent migration (1.5%). In 13 diabetic patients, tibial PTA was also associated. Additional treatment was required in 6 D and 1 non-D. CONCLUSIONS The use of Zilver PTX is safe and effective in the treatment of SFA lesions. In particular, both stent patency and functional results on the basis of both clinical and instrumental tools were similar in D and non-D, suggesting a particularly favorable activity of PTX in a subpopulation of diabetics. Further studies are required to confirm these results, which seem to be particularly promising in diabetic patients.

Abstract
Surgical treatment of abdominal aortic aneurysm after previous pneumonectomy is a challenge because of the impaired respiratory function and increased surgical risks. Endovascular aneurysm repair in anatomically suited high-surgical-risk patients offers excellent short-term results and provides good protection from aneurysm-related death. In this article, we report a successful endovascular aneurysm repair of an infrarenal aortic aneurysm in a patient with past left pneumonectomy.

Abstract
AIM The induction of sleep would depend on interaction between gabaergic system and the pineal gland through its main hormone melatonin. Until few years ago benzodiazepines were the only drugs effective in the treatment of insomnia. Recently, however, both melatonin and acupressure have appear to be active in sleep disorders. The aim of study was to evaluate the efficacy of HT 7 point acupressure in insomnia. METHODS The study enrolled 25 patients affected by sleep disorders, 14 of whom had a neoplastic disease. They were treated by HT 7 stimulation for al least two consecutive weeks using a medical device named H7 Insomnia Control. RESULTS An improvement in the quality of sleep was achieved in 15/25 (60%) patients, with a more evident efficacy in cancer patients (11/14 [79%]). CONCLUSION This study confirms previous clinical data showing the efficacy of acupressure in the treatment of sleep disorders, particularly in cancer-related insomnia.

Abstract
AIM The recent rediscovery of the natural traditional medical sciences has contributed to improve the treatment of the human diseases and, in particular, it has been shown that the pharmacological approach is not the only possible strategy in the treatment of nausea and vomiting, since bioenergetic approaches, such as acupressure and acupuncture, may also counteract the onset of vomiting due to different causes. Previous preliminary clinical studies had already suggested a possible efficacy of acupressure also in the treatment of chemotherapy-induced vomiting resistant to the classical antiemetic drugs. The aim of this study was to confirm these preliminary data. METHODS The study was performed in 100 consecutive metastatic solid tumour patients, who underwent chemotherapy for their advanced neoplastic disease, and who had no benefit from the standard antiemetic agents, including corticosteroids, antidopaminergics and 5-HT 3R-antagonists. Acupressure was made by a stimulation of PC6 acupoint. RESULTS The emetic symptomatology was reduced by acupressure in 68/100 (68%) patients, without significant differences in relation to tumour histotype. The lowest efficacy was observed in patients treated by anthracycline-containing regimens, without, however, statistically significant differences with respect to the other chemotherapeutic combinations. CONCLUSION This study confirms previous preliminary clinical results, which had already suggested the potential efficacy of acupressure in the treatment of vomiting due to cancer chemotherapy. Therefore, acupressure may be successfully included within the therapeutic strategies of cancer chemotherapy-induced vomiting.

Abstract
AIM Alopecia still remains one of the most untreatable side-effects induced by cancer chemotherapy. According to the phytotherapeutic tradition, Panicum Miliaceum has been proven to be effective in the prevention of hair loss for different reasons. At present, however, there are no data about its possible efficacy in the treatment of cancer chemotherapy-induce alopecia. The aim of this study was to analyze the efficacy of Panicum Miliaceum in cancer patients treated with the most potent chemotherapeutic drugs in terms of hair loss, consisting of cisplatin (CDDP) and anthracyclines. METHODS This case-control study included 28 cancer patients concomitantly treated with Panicum Miliaceum and 56 patients receiving the same combinations of chemotherapy alone as a control group. Panicum Miliaceum was given orally at 300 mg (daily dose) 3 times per day, every day until the end of chemotherapy. The grade of hair loss was assessed by World Health Organization (WHO) criteria. RESULTS The percentage of alopecia of third grade observed in patients concomitantly treated with Panicum Miliaceum in association with CDDP-containing regimens was significantly lower than that found in those who received the chemotherapy only. The percentage was also lower under anthracycline-containing schedules, without, however, statistically significant differences. Panicum Miliaceum therapy was substantially well tolerated in all patients. RESULTS This preliminary study would suggest that the concomitant treatment with Panicum Miliaceum may be effective in preventing hair loss induced by CDDP-containing chemotherapies, whereas the benefit was lower in patients treated with anthracyclines. Future randomized studies will be necessary to confirm these preliminary

Abstract
Here we report a rare case of a 74-year-old man with a pseudoaneurysm of the anterior tibial artery and a concomitant arteriovenous fistula (AVF). The patient was admitted because of increasing pain following the formation of a large mass located in the anterior mid-portion of the calf after a moderate non-penetrating blunt trauma. A polytetrafluoroethylene-covered stent was placed over the origin of the pseudoaneurysm, with complete exclusion of the pseudoaneurysm and disappearance of the AVF. One year after the procedure the mass had completely disappeared and the vascular anatomy of the calf is well preserved.

Abstract
AIM Corticosteroids, antidopaminergig agents and 5-HT3 antagonists are the most commonly used drugs in the treatment of chemotherapy-induced vomiting. Acupuncture and acupressure have also appeared to exert antiemetic effects. The aim of this study was to evaluate the efficacy of acupressure in the treatment of chemotherapy-induced vomiting resistant to the standard antiemetic therapies. METHODS The study included 40 consecutive advanced cancer patients with untreatable chemotherapy-induced vomiting. Colorectal cancer, lung cancer and breast cancer were the neoplasm most frequent in our patients. According to tumour histotype, patients received chemotherapeutic regimens containing the main emetic cytotoxic agents, including cisplatin and athracyclines. Acupressure was made by PC6 point stimulation for at least 6 h/day at the onset of chemotherapy. RESULTS The therapeutic approach was well accepted by the overall patients. An evident improvement in the emetic symptomatology was achieved in 28/40 (70%) patients, without significant differences in relation to neither tumor histotype, nor type of chemotherapeutic agent. CONCLUSIONS This preliminary study seems to suggest that a bioenergetic approach by acupressure on PC6 point may be effective in the treatment of chemotherapy-induced vomiting resistant to the conventional pharmacological strategies, as previously demonstrated for vomiting occurring during pregnancy.

Abstract
In addition to the occurrence of pain, the evidence of a diminished capacity to feel pleasure is one of the most common cancer-related symptoms. Recent advances in psychoneuroendocrinological knowledge has shown that the perception of pleasure is mainly mediated by the dopaminergic pathways in the brain. Moreover, it has also been demonstrated that the brain dopaminergic sensitivity may be clinically explored by evaluating the endocrine response to the administration of dopaminergic agents, such as apomorphine, which consists of a decline in PRL concentrations and an increase in GH and cortisol levels. The present study was performed to evaluate dopaminergic sensitivity by the administration of apomorphine in cancer patients in an attempt to document possible cancer-related neuroendocrine anomalies, which could explain the psychological status of the patients. The study included 24 cancer patients (breast cancer: 12; colorectal cancer: 7; non-small cell lung cancer: 5), 12 of whom showed distant organ metastases. Apomorphine was given orally at 0.01 mg/kg b.w., by collecting venous blood samples before and after 20 and 60 minutes. A normal decline in PRL levels was seen in both non-metastatic and metastatic cancer patients. No cortisol increase in response to apomorphine was achieved and the lack of cortisol response was particularly evident in metastatic patients. No GH rise occurred in either metastatic or non-metastatic cancer patients. Finally, no significant difference in the endocrine response to apomorphine was seen in relation to the histotype of tumor. The results of this study show that the neoplastic disease is characterized by neurochemical alterations involving pleasure-related dopaminergic pathways, which are more evident in the metastatic disease, without particular differences in relation to tumor histotype. Therefore, the psychological condition of cancer patients would not depend only on psychological factors, but it could be due at least in part to cancer-related neuroendocrine alterations involving the dopaminergic system.

Abstract
The possibility of natural cancer therapy has been recently suggested by advances in the knowledge of tumor immunobiology. Either cytokines such as IL-2, or neurohormones, such as the pineal indole melatonin (MLT), may activate anticancer immunity. In addition, immunomodulating substances have also been isolated from plants, particularly from Aloe vera. Preliminary clinical studies had already shown that MLT may induce some benefits in untreatable metastatic solid tumor patients, whereas, for the time being, no clinical trial has been performed with aloe products. We have carried out a clinical study to evaluate whether the concomitant administration of aloe may enhance the therapeutic results of MLT in patients with advanced solid tumors for whom no effective standard anticancer therapies are available. The study included 50 patients suffering from lung cancer, gastrointestinal tract tumors, breast cancer or brain glioblastoma, who were treated with MLT alone (20 mg/day orally in the dark period) or MLT plus A. vera tincture (1 ml twice/day). A partial response (PR) was achieved in 2/24 patients treated with MLT plus aloe and in none of the patients treated with MLT alone. Stable disease (SD) was achieved in 12/24 and in 7/26 patients treated with MLT plus aloe or MLT alone, respectively. Therefore, the percentage of nonprogressing patients (PR + SD) was significantly higher in the group treated with MLT plus aloe than in the MLT gorup (14/24 vs. 7/26, p < 0.05). The percent 1-year survival was significantly higher in patients treated with MLT plus aloe (9/24 vs. 4/26, p < 0.05). Both treatments were well tolerated. This preliminary study would suggest that natural cancer therapy with MLT plus A. vera extracts may produce some therapeutic benefits, at least in terms of stabilization of disease and survival, in patients with advanced solid tumors, for whom no other standard effective therapy is available.

Abstract
Stress is laid on the important role that lumbar gangliectomy has acquired among treatments of chronic arteriopathies of the lower extremities. For patients at Leriche 2nd stage and suffering from obstructions confined to the superficial femoral, no other treatment would appear to boast such high success percentages over time. General surgeons are invited to make use of this comparatively simple and certainly effective intervention, in consideration of the fact, among others, that the few vascular surgery centres in existence are not in a position to meet the flow of requests from the arteriopathics who apply to them.

Abstract
The aetiopathogenesis and diagnosis of Martorell's supra-malleolar hypertensive ulcer are discussed in the light of 3 clinical cases. Stress is laid on the overriding need for proper general management designed to normalise the serious arterial hypertension. It is felt that raubasine vasokinetics (such as Circolene), and taurine tissue oxygenators (0-due) are useful supplementary aids, particularly when administered by slow infusion. Lumbar gangliectomy will be necessary in the case of persistently painful ulcers. Its success, however, is dependent on prior normalisation of pressure. Dermo-epidermal grafts would appear to be superfluous, while frequent topical application of trophodermic creams are apparently useless.
