RESUMO

PURPOSE: Cardiovascular disease (CVD) is the first cause of death in patients with non-alcoholic fatty liver disease (NAFLD) and risk stratification is recommended by current guidelines. The aim of this study is to assess the prevalence of peripheral arterial disease (PAD) in patients with NAFLD and its association with all-cause and cardiovascular disease (CVD) mortality. METHODS: 9145 participants 40 years or older attended a mobile examination center visit in the 1999-2004 cycles of the National Health and Nutrition Examination Survey. PAD was defined as an ankle-brachial index (ABI) < 0.90 in either of the legs and mortality data through December 2015 were obtained from the National Death Index. NAFLD was defined by a fatty liver index ≥ 60 in the absence of other liver conditions, leading to a final sample of 3094 subjects. RESULTS: The overall prevalence of PAD was 5.9% (95% CI 5.0-6.9). Over a median follow-up of 13 years, 876 participants died, 208 of cardiovascular causes. Incidence rates of all-cause mortality (for 1000 person-years) were 20.2 (95% CI 18.7-21.7) and 70.0 (95% CI 60.1-81.6) for participants without and with PAD, respectively. Multivariable-adjusted Cox proportional hazard models showed that PAD was associated with a higher risk of all-cause (1.8, 95% CI 1.4-2.4) and cardiovascular mortality (HR 2.5, 95% CI 1.5-4.3) after adjustment for potential confounders including prevalent CVD. CONCLUSION: Current guidelines strongly encourage the screening of CVD in patients with NAFLD and the use of the simple and inexpensive measurement of ABI in routine clinical practice may find indication.

RESUMO

OBJECTIVES: To analyze feasibility and outcomes of endovascular aortic repair (EVAR) with a strictly on-label use of abdominal aortic endografts (OnL-EVAR) to treat para-anastomotic aneurysms (PAAs) and pseudoaneurysms (PSAs) after infrarenal abdominal aortic aneurysm open repair (OR). METHODS: The data of all consecutive patients treated between 1999 and 2012 for non-infected abdominal PAAs and PSAs at our center were prospectively collected. All cases fit for EVAR based on the instructions for use of a series of abdominal aortic endografts commercially available during the study period were scheduled for OnL-EVAR regardless of patients' surgical risk. Any patients unfit for OnL-EVAR underwent OR or other complex endovascular techniques. RESULTS: One hundred and forty-three patients were collected; 78 underwent OR and 65 endovascular repair with different strategies. Coil embolization, hybrid, and chimney/periscope grafts techniques were limited to seven patients unfit both for OR and OnL-EVAR. Inclusion criteria for OnL-EVAR were reached in 58 patients for an overall OnL-EVAR feasibility of approximately 40% (21% for PAAs and 55% for PSAs). In particular, OnL-EVAR feasibility was 19% in case of involvement of proximal aortic anastomosis, 71% for distal aortic anastomosis, and 80% for iliac arteries. Overall, 25 aortouniiliac and 11 bifurcated implants were performed, single proximal aortic cuffs were used in 10 patients, and iliac extension in 12. Primary technical success was 98% without perioperative mortality. At a median follow-up of 67 months (range: 1-144 months), cumulative aneurysm-related mortality was 7%, endograft migration 7%, and reintervention was 17%. Life-table analysis showed actuarial survival and freedom from aneurysm-related death at 1, 3, and 5 years of 100%, 98%, and 95%, and of 100%, 98%, and 95%, respectively. Freedom from aortic reintervention or open conversion at 1, 3, and 5 years was 94%, 90%, and 85%. CONCLUSIONS: Feasibility of OnL-EVAR was limited for PAAs and PSAs, with a rate that was lower than 20% in case of involvement of proximal aortic anastomosis. Aortouniiliac configuration was the most commonly feasible implant and, despite strict on-label use of abdominal devices, the rate of late complications and reinterventions was high.

RESUMO

OBJECTIVES: Despite several advances in endoluminal salvage for failed endovascular abdominal aortic repair (EVAR), in our experience an increasing number of cases necessitate delayed open conversion (dOC). METHODS: EVAR patients requiring delayed (>30 days) conversion were prospectively collected in a computerized database including demographics, details of aortoiliac anatomy, procedural and clinical success, and postoperative complications. RESULTS: Between 2005 and 2011, 54 patients were treated for aortic stent-graft explantation. Indications included 34 type I and III endoleaks, 13 type II endoleaks with aneurysm growth, 4 cases of material failures, and 3 stent-graft infections. All fit-for-surgery patients with type I/III endoleak underwent directly dOC. Different surgical approaches were used depending on the type of stent-graft. Overall 30-day mortality was 1.9%. Overall morbidity was 31% mainly due to acute renal failure (13 cases). Mean hospitalization was 6 days (range, 5-27 days). Overall survival at mean follow-up of 19 months was 78%. CONCLUSIONS: In recent years, the use of EVAR has increased dramatically, including in young patients regardless of their fitness for open repair. dOC after endovascular abdominal aortic aneurysm seems to be a lifesaving procedure with satisfactory initial and mid-term results.

RESUMO

INTRODUCTION: Recognition of acute mesenteric ischaemia (AMesI) in patients with aortic dissection (AoD) may be a challenge and exploratory laparotomy is often performed. METHODS: We retrospectively analysed our experience with the use of diagnostic laparoscopy (DL) for the early detection of AMesI in patients with AoD, either undergoing medical treatment or after open/endovascular interventions. RESULTS: Between 2004 and 2011, 202 consecutive AoDs were treated in our centre (71 acute type A AoD; 131 acute and chronic type B AoD). Among the 17 (8.4%) patients in which AMesI was suspected, nine (52.9%) were selected for DL. Three DLs were performed during medical treatment of patients with acute type B AoD, six after treatment of AoD (both surgical and endovascular). Three second-look DLs were also performed. Eight DLs were negative, three showed AMesI and the patients underwent successful emergent revascularisation. One DL was not conclusive and laparotomy was required. Among the eight patients not submitted to DL, one case of bowel infarction was recorded. CONCLUSIONS: In our series DL was feasible and safe. The low invasiveness and repeatability were the main advantages. Although additional experience is mandatory, DL seems a promising technique for the detection of AMesI in patients with AoD.

RESUMO

OBJECTIVE: We evaluated the incidence of aorto-oesophageal (AEF) and aortobronchial (ABF) fistulae after thoracic endovascular aortic repair (TEVAR), and investigated their clinical features, determinants, therapeutic options and results. METHODS: We conducted a voluntary national survey among Italian universities and hospital centres with a thoracic endovascular programme. RESULTS: Thirty-nine centres were contacted, and 17 participated. Of the patients who underwent TEVAR between 1998 and 2008, 19/1113 (1.7%) developed AEF/ABF. Among indications to TEVAR, aortic pseudo-aneurysm was associated with the development of late AEF/ABF (P = 0.009). Further, emergent and complicated procedures resulted in increased risk of AEF/ABF (P = 0.008 and P < 0.001, respectively). Eight patients were treated conservatively, all of whom died within 30 days. Eleven patients underwent AEF/ABF surgical treatment, with a perioperative mortality of 64% (7/11). At a mean follow-up of 17.7 +/- 12.5 months, overall survival was 16% (3/19). CONCLUSIONS: The incidence of AEF and ABF following TEVAR is not negligible, and is comparable to that following open repair. This finding warrants an ad hoc long-term follow-up after TEVAR, particularly in patients submitted to emergent and complicated procedures. Both surgical and endovascular treatment of AEF/ABF are associated with high mortality. However, conservative treatment does not appear to be a viable option.

RESUMO

Thoracic endovascular aortic repair (TEVAR) has emerged as a promising, less invasive alternative to conventional open surgery for the treatment of thoracic aortic pathology. Most surveillance after TEVAR concentrates on the technical aspects of the procedure, including endoleak, device migration and endograft rupture; so far, the knowledge on endograft infectious complications is limited to anecdotal reports. Several etiopathogenetic factors may play a role in thoracic endograft infections (TEIs), including perioperative contamination, hematogenous seeding, and local bacterial translocation. Moreover, fistulization with the esophagus or the bronchial tree is a common mechanism of secondary TEI, and it represents a dramatic event requiring a multidisciplinary management. Risk factors assessment and prevention have a key role in avoiding the development of new TEIs. When a TEI is established, treatment is demanding, and includes several medical therapies associated with various surgical options. Patients are usually severely compromised by sepsis, and in most cases they are considered unfit for surgery for general clinical conditions or local concerns. Thus, results of different therapeutic strategies for TEI are still burdened with very high morbidity and mortality. In this paper, we reviewed the English literature regarding the main strategies proposed for operative management of TEI, we reported and analyzed our personal series of 7 patients treated at our institution for TEI from 1999 to 2009, and we summarized results from the data collected during a recent Italian multicenter national survey, performed to investigate aortoesophageal and aortobronchial fistulae treated with TEVAR or developed following TEVAR.

RESUMO

The search for less invasive therapeutic approaches to thoracoabdominal aortic aneurysms (TAAAs) brought endovascular procedures to establish themselves as alternatives to open surgery in high-risk patients. Aim of this study is to illustrate the hybrid - open and endovascular - treatment of dissecting and non-dissecting TAAAs, and to analyze short and midterm results at our Center. We analyzed 41 high-risk patients who underwent hybrid TAAA repair (dissecting TAAA in 17% of cases) with a variety of visceral rerouting configuration and of commercially available thoracic endografts. Thirty-one simultaneous (76%) and 10 staged procedures (24%) were performed with a four-vessel revascularization in 13 cases (32%), a three-vessel in 9 (22%) and a two-vessel in 19 (46%). No intraoperative deaths were observed in our series, with a technical success in endovascular TAAA repair of 100%. Two patients died in the intersurgical time. A perioperative mortality of 13% and a perioperative morbidity of 32% were recorded, including one case (2.4%) of permanent paraplegia. At a median follow-up of 23.3 months, we observed a visceral graft occlusion rate of 6%, three type II endoleak and one endograft migration. Six patients died for unrelated events. Typical complications of conventional TAAA open surgery have been not eliminated by hybrid repair and still significant mortality and morbidity have been reported. Dissecting etiology did not negatively affect the outcome of hybrid repair in our experience. Fate of visceral bypasses and incidence of endoleak and other endograft-related complications need to be carefully assessed. Hybrid TAAA repair should nowadays be limited as alternative to simple observation in patients unfit for the conventional open repair.

RESUMO

OBJECTIVES: To assess self-management of chronic venous disorders (CVDs) in a selected Italian population and the pattern of prescription by selected Italian phlebologists. DESIGN: Cross-sectional study carried out between 2003 and 2005. MATERIALS: Non-random, transverse sample of men and women recruited by advertising. METHODS: Assessment of therapeutic habits of respondents, treatment advice given by phlebologists related to socio-demographic variables and severity of the disease. Multivariate odds ratios for sex, age, class, region, family history and severity of the disease. RESULTS: Women undergo CVD therapy more than men (odds ratio (OR): 2.37 for medical treatment; 1.29 for surgical treatment and 5.72 for sclerotherapy). Young people prefer drug treatment to compression stockings. Drug therapy for CVD is 1.5 times more likely in southern Italian respondents, as is compression stockings (OR: 1.91). Surgical therapy is more frequent in Northern Italy (OR for Central Italy: 0.79; Southern Italy and Islands: 0.76). Family history of CVD leads people to early treatment of symptoms. CONCLUSIONS: This study provides insight into self-medication of CVD in Italy and the prescribing patterns of Italian phlebologists in the treatment of CVD. It shows that the population interviewed is able to practise responsible self-medication of their CVD problems.

RESUMO

Surgical treatment of pararenal aortic aneurysms, if compared to open repair of infrarenal aneurysms, is characterized by more technical difficulties and haemodynamic problems. Since endovascular repair has become feasible in most cases of infrarenal aneurysms, surgical treatment of pararenal aneurysms is a matter of great interest for vascular surgery. Detection of pararenal aneurysms needs a careful preoperative diagnosis, assessment of cardiac, renal and pulmonary status of the patient and planning of the surgical intervention. The surgeon needs to face an extended proximal aorta exposure, to manage the left renal vein and to choose an appropriate clamping site. Then a skilled and quick reconstruction of the visceral arteries is fundamental to minimize organ disfunction. Coupled intraoperative selective perfusion of visceral arteries and systemic administration of nephroprotective drugs optimizes organ protection during ischemia. To better define challenges, risks and results, we reviewed our experience with the treatment of pararenal aortic aneurysms. In the period between January 1993 and May 2003, 98 consecutive patients underwent surgery for pararenal aneurysms at our Institution. We treated 98 pararenal aneurysms, divided in 68 juxtarenal and 30 pararenal ones. In the juxtarenal aneurysms group, the 30 days mortality rate was 5.8% (4/68); 3 of these patients underwent urgent operation for ruptured aneurysm. In the suprarenal aneurysms group, the 30 days mortality rate was 3.3% (1/30). In conclusion pararenal aneurysm repair is a safe procedure, especially if performed electively, and represents an interesting field of research to improve surgical and anesthesiologic techniques.

RESUMO

The INCRAFT® AAA Stent Graft System is the advanced endovascular aneurysm repair (EVAR) technology for the treatment of infrarenal abdominal aneurysms. This new system is designed to address the unmet needs of current endografts by combining unique features and adding new refinements compared to existing endografts delivered through a flexible 14-Fr ultra-low system. The INCRAFT® AAA Stent Graft System introduces innovative features without deviating from proven stent-graft design principles. It is a three-piece modular system, made of low porosity polyester and segmented nitinol stents. However, the introduction of cap-free delivery and partial proximal repositioning enhances the ability of the device to better match individual aortoiliac anatomy with a high deliverability and placement accuracy in a easy to use system. Moreover, the INCRAFT® System allows a "customization" of the implant during the procedure with bilateral in-situ length adjustment features. The present data from the ongoing clinical trials confirm excellent results with this system, but postmarket studies will be necessary to verify the effectiveness of this system in the real-world setting.

RESUMO

AIM: In the last two decades, results of endovascular aortic repair (EVAR) for the treatment of infrarenal abdominal aortic aneurysms (AAAs) have significantly improved thanks to the evolution of stent-grafts and endovascular delivery systems. However, further development is still needed to reduce the incidence of complications and secondary reinterventions. We present our initial experience with the Treovance abdominal aortic stent-graft (Bolton Medical, Barcelona, Spain), a new-generation trimodular endovascular device, developed to increase flexibility, lower profile, improve deployment and sealing mechanisms. METHODS: We treated 8 patients with anatomically suitable non-ruptured AAA. RESULTS: Primary technical success was obtained in all patients, and no 30-day device-related complications nor deaths were reported. One patient experienced graft limb occlusion at 3 months, and underwent surgical conversion. At 1-year follow-up (completed in 6 patients), no device-related complications nor type I or III endoleak were observed. CONCLUSION: Initial personal experience with the Treovance abdominal stent-graft was satisfactory with regard to technical success and short-term clinical results. This new-generation endovascular device performed well even in angulated or heavily calcified anatomies.

RESUMO

AIM: Endovascular repair of the thoracic aorta (TEVAR) has been recently considered an appealing alternative to open treatment of traumatic aortic injuries. However, the use of this technique in emergency is often limited by hemodynamic instability, severe associated lesions and unavailability of adequate materials. Dedicated stent-grafts are not currently available. We report our results in treating blunt traumas of the thoracic aorta using three different commercially available stent-grafts. METHODS Between 2003 and 2010, 28 patients (22 males, mean age 38.9±12.1 years) underwent TEVAR for a traumatic aortic lesion. A total-body computed tomography angiography (CTA) was performed in all cases to establish the diagnosis of aortic rupture and evaluate associated injuries. After TEVAR, patients were followed-up with CTA of the chest before discharge from the hospital, at 6 months and yearly thereafter. RESULTS: Fifteen patients (54%) were hemodynamically unstable at presentation, and 20 patients (71%) presented severe associated lesions. The mean injury severity score (ISS) was 36.2. Twenty-four patients were treated emergently, whereas four patients underwent prior clinical stabilization of severe associated injuries. Primary technical success rate was 100%. No patient required conversion to open thoracic surgical repair. No paraplegia or stroke was observed. Procedure-related complications included an external iliac artery lesion during introducer sheath removal. The left subclavian artery was intentionally covered in 7 cases (25%), and revascularized in two hemodynamically stable patients prior to stent-graft deployment. Two patients died perioperatively due to multiorgan failure, for a total in-hospital mortality of 7%. Twenty-four patients (92% of survivors) adhered to the follow-up protocol (mean 37.3±17.5 months), and they are all alive without instances of reintervention. CONCLUSION: In our experience, endovascular treatment of acute traumatic thoracic aortic injuries using different commercially available stent-grafts allows to obtain satisfactory short term results.

RESUMO

Occlusion of the infrarenal aorta (IAO) represents from 3% to 8.5% of aortoiliac occlusive diseases, and is a variant of TransAtlantic Inter-Society Consensus (TASC) Type D lesions. Two different patterns of IAO can be identified: Distal and proximal, or iuxtarenal. The former typically spares the origin of the inferior mesenteric artery, and is associated with the classic Leriche clinical triad. The latter extends cephalad approaching the level of the renal arteries, and may also cause acute renal failure, intestinal infarction, and even paraplegia due to the proximal propagation of aortic thrombosis. Endovascular treatment for TASC Type C and D lesions as a whole provides impressive results in terms of periprocedural morbidity, secondary patency rates, and of course less invasivity in comparison to open surgery. However, when complete aortic occlusions, and particularly juxtarenal occlusion, are specifically addressed, the reported results are in fact sobering, both in terms of technical success rates, and perioperative complications. Surgery repair of juxtarenal aortic occlusion, namely aortic endarterectomy and bypass grafting, is a challenging procedure that requires almost invariably aortic cross-clamping above the level of the renal arteries, and may be associated with significant morbidity and mortality. Nevertheless, it currently provides unmatched perioperative and long-term results, and should be regarded as the treatment of choice.

RESUMO

The aim of this study was to describe the technique and report our single center experience of abdominal aortic aneurysm (AAA) open surgical repair over the last 17 years. From 1993 to 2010, a total of 4347 open surgical procedures for repair of AAA were performed in our center. The details of 3857 (88.7%) patients undergoing infrarenal AAA open repair were analyzed; mean age at the time of surgery was 71.8 years ranging from 58 to 89 years. Among all repairs, 23.7% (914) were performed in women and 24.3% (937) in octogenarians; 3587 (93.0%) procedures were performed for degenerative aneurysms, 146 (3.8%) for inflammatory aneurysms, 100 (2.6%) for dissecting aneurysms, and 19 (0.5%) for other pattern of disease. In 162 cases (4.2%) surgery was performed for ruptured aneurysm. In most cases (N.=2596; 67.3%) infrarenal AAA open repair was performed by means of aorto-aortic bypass using a tube graft. A total of 1261 patients were treated using a bifurcated graft: 417 (33.1%) aorto-iliac bypasses, 530 (42.0%) aorto-femoral bypasses and 314 (24.9%) aorto-iliac-femoral bypasses were performed. In elective aorto-aortic bypass, mean aortic clamping time was 21.3+6.7 minutes. The average duration of the procedure was 126+84 minutes (range, 42-410 minutes). Mean intraoperative bleeding was 803.4+422.7 mL (range 250-3,100). Overall intraoperative mortality was 0.2%. Intraoperative mesenteric ischemia was observed in 3% of cases, all treated with inferior mesenteric artery reimplantation. The rate of intraoperative lower limbs ischemia was 2.2%. One intraoperative acute type A aortic dissection occurred. The overall 30-day mortality was 0.6%. Permanent renal function impairment occurred in 4.3% of cases. The rate of pulmonary complications was 9.8%. Other complications were myocardial infarction, congestive heart failure, late ischemic colitis, late leg ischemia, wound infection, urinary tract infection, and sepsis. Although endovascular techniques have emerged as a less invasive alternative to open repair, short- and long-term outcomes associated to the surgery of infrarenal AAAs remain satisfactory for a large range of patients.

RESUMO

Endovascular aortic repair (EVAR) has emerged as a promising, less invasive alternative to conventional open surgery for the treatment of infrarenal abdominal aortic aneurysms (AAAs). In the last 20 years, the application rate of EVAR and its clinical results have significantly improved thanks to the evolution of stent-grafts and endovascular delivery systems. However, further development is still needed to reduce the incidence of complications and secondary re-interventions. The Treovance abdominal aortic stent-graft (Bolton Medical, Barcelona, Spain) is a new-generation endovascular device, developed to increase flexibility, lower profile, improve deployment and sealing mechanisms. In particular, it is provided with some innovative features as a double layer of proximal barbs (suprarenal and infrarenal) for supplemental fixation, dull barbs between modules to avoid potential leg disconnections, detachable outer sheath provided with a new-design hemostatic valve, and a double improved mechanism (slow motion and "pin and pull") for precise stent-graft deployment. A European prospective, non-randomized, multi-institutional, "first-in-human" trial (the ADVANCE trial) was conducted from March to December 2011 to assess the safety and performance of the Treovance stent-graft system before commercialization. Thirty patients with anatomically suitable non-ruptured AAAs were enrolled at five clinical sites in Italy, Spain, and Germany. EVAR was completed successfully in all patients. The stent-graft was delivered and deployed safely even in heavily angulated or calcified anatomies. No 30-day device-related complications nor deaths were observed. Preliminary experience with the Treovance abdominal stent-graft within the ADVANCE trial was satisfactory with regard to technical success and perioperative clinical results. Follow-up data are needed to assess mid- and long-term clinical outcomes, along with durability of this new-generation endovascular device.

RESUMO

Optimal treatment for synchronous aortic aneurysms is still debated. Staged repair is advocated as the standard of care. Its disadvantage however is the consistent risk of rupture of the untreated aortic segment during recovery; moreover a considerable percentage of patients either refuse the second stage or is lost to follow-up. We present the case of a patient with a ruptured aortic arch aneurysm after open-surgery for a type III thoracoabdominal aortic aneurysm. Our therapeutic decision is described and discussed, with all the related advantages and disadvantages.

RESUMO

Carotid endarterectomy plays an important role in the prevention of ischemic stroke; patching could reduce the risk of intra- and postoperative complications and late restenosis among primary closure. Materials actually available for the patch tailoring are synthetic or biological: which is the best is still debated. We present the case of a polyurethane (PU) carotid patch rejection three years after its implant, with no evident arterial discontinuity and no sign of infection. Histopathological analysis on hematoxylin-eosin stained sections of the regenerated arterial wall tissue removed revealed plasma cell infiltration and clusters of foreign body giant cells. PU patch rejection has been seldom described in literature. This is an unusual late complication that should be considered at long-term follow-up evaluation of these patients.

RESUMO

INTRODUCTION: Current strategies for repair of descending thoracic aortic aneurysms consist of open repair with surgical graft replacement or thoracic endovascular aortic repair. We review and update our overall experience in aortic thoracic diseases and specifically analyzed our outcomes with thoracic endovascular aortic repair in patients with descending thoracic aortic aneurysms. METHODS: From 1993 to present a total of 1144 patients were treated in our Center for pathology involving the thoracic aorta. Since 1998, 322 patients underwent thoracic endovascular aortic repair, and among this group, in 188 cases the descending aorta was involved. In 74% of patients treated for a descending thoracic aortic lesion, a degenerative aneurysm was observed. RESULTS: In patients with descending thoracic aortic aneurysms receiving thoracic endovascular aortic repair, our technical success rate, i.e. deployment of endograft with complete exclusion of the lesion/minimal endoleak, was 99.5% (one case required emergent open conversion) with a perioperative mortality of 2.6% (five patients). The rate of spinal cord ischemia, manifesting either as paraplegia or paraparesis, was 4.7%. Delayed onset spinal cord ischemia ameliorated with adequate arterial pressure and cerebrospinal fluid drainage. CONCLUSIONS: Our experience of selected patients undergoing thoracic endovascular aortic repair of descending thoracic aorta aneurysms is satisfactory with very low mortality and morbidity. A large use of thoracic endovascular aortic repair is foreseen in the next future.
