Gender-Related Disparities Among Vascular Surgeons in Italy: Results from a Cross-Sectional Survey.

BACKGROUND: To assess the presence, quality and impact of gender-related discrepancies in academic vascular surgery at a national level. METHODS: This was an anonymous national structured nonvalidated cross-sectional survey on gender disparity perceptions, named "I love it when you call me Señorita", distributed to 645 participants from academic Italian vascular centers. Endpoints were related to job-related characteristics, satisfaction, and sexual harassment. RESULTS: The survey yielded a 27% response rate (n = 174, 78 males and 96 females). Significant differences between male and female responders were found in terms of job satisfaction (83.3% vs. 53.1%, P < 0.001), perception of career opportunities (91.7% vs. 67.9%, P < 0.001), surgical activity in the operating theater (34.6% vs. 7.3%, P < 0.001), involvement in scientific activities (contribution in peer-reviewed articles: 37.2% vs. 9.4%, P < 0.001; scientific meeting attendance/year: 42.3% vs. 20.8%, P = 0.002), and perception of lower peer support at work (2.6% vs. 22.9%, P < 0.001). In addition, female physicians more frequently suffered sexual harassment from male peers/colleagues (10% vs. 34%, P < 0.001), male health-care workers (7% vs. 26%, P = 0.001), or patients/caregivers independently from their sex (6% vs. 38.5%, P < 0.001 for males and 5% vs. 22%, P = 0.001 for females). CONCLUSIONS: A significant number of the female vascular surgeons in Italian academic vascular centers responding to the survey have experienced workplace inequality and sexual harassment. Substantial efforts and ongoing initiatives are still required to address gender disparities, emphasizing the need for the promotion of specific guidelines within scientific societies.

Fate of target visceral vessels in fenestrated and branched complex endovascular aortic repair.

OBJECTIVE: To assess branch vessel outcomes after endovascular repair of complex aortic aneurysms analyzing possible factors influencing early and long-term results. METHODS: The Italian Multicentre Fenestrated and Branched registry enrolled 596 consecutive patients treated with fenestrated and branched endografts for complex aortic disease from January 2008 to December 2019 by four Italian academic centers. The primary end points of the study were technical success (defined as target visceral vessel [TVV] patency and absence of bridging device-related endoleak at final intraoperative control), and freedom from TVV instability (defined as the combined results of type IC/IIIC endoleaks and patency loss) during follow-up. Secondary end points were overall survival and TVV-related reinterventions. RESULTS: We excluded 591 patients (3 patients with a surgical debranching and 2 patients who died before completion from the study cohort) were treated for a total of 1991 visceral vessels targeted by either a directional branch or a fenestration. The overall technical success rate was 98.4%. Failure was related to the use of an off-the-shelf (OTS) device (custom-made device vs OTS, HR, 0.220; P = .007) and a preoperative TVV stenosis of >50% (HR, 12.460; P < .001). The mean follow-up time was 25.1 months (interquartile range, 3-39 months). The overall estimated survival rates were 87%, 77.4%, and 67.8% at 1, 3, and 5 years, respectively (standard error [SE], 0.015, 0.022, and 0.032). During follow-up, TVV branch instability was observed in 91 vessels (5%): 48 type IC/IIIC endoleaks (2.6%) and 43 stenoses-thromboses (2.4%). The extent of aneurysm disease (thoracoabdominal aortic aneurysm [TAAA] types I-III vs TAAA type IV/juxtarenal aortic aneurysm/pararenal aortic aneurysm) was the only independent predictor for developing a TVV-related type IC/IIIC endoleak (HR, 3.899; 95% confidence interval [CI]:, 1.924-7.900; P < .001). Risk of patency loss was independently associated with branch configuration (HR, 8.883; P < .001; 95% CI, 3.750-21.043) and renal arteries (HR, 2.848; P = .030; 95% CI, 1.108-7.319). Estimated rates at 1, 3, and 5 years of freedom from TVV instability and freedom from TVV-related reintervention were 96.6%, 93.8%, and 90% (SE, 0.005, 0.007, and 0.014) and 97.4%, 95.0%, and 91.6% (SE, 0.004, 0.007, and 0.013), respectively. CONCLUSIONS: Intraoperative failure to bridge a TVV was associated with a preoperative TVV stenosis of >50% and the use of OTS devices. Midterm outcomes were satisfying, with an estimated 5-year freedom from TVV instability and reintervention of 90.0% and 91.6%, respectively. During follow-up, the larger extent of aneurysm disease was associated with an increased risk of TVV-related endoleaks, whereas a branch configuration and renal arteries were more prone to patency loss.

Elective or Urgent Carotid Endarterectomy in Symptomatic Patients: Analysis Based on the Type and Timing of Neurological Symptoms.

BACKGROUND: The aim of this study was to retrospectively analyse perioperative and long-term outcomes of carotid endarterectomy (CEA) performed in symptomatic patients in a high-volume academic vascular centre, stratifying them according to the type of preoperative symptoms and the timing of surgery with respect to the indexed neurological event. METHODS: From January 2014 to December 2020, 1,369 consecutive CEAs were performed at our institution. Data concerning these interventions were prospectively collected in a dedicated database including data concerning preoperative assessment, surgical details, perioperative (<30 days) outcomes, and long-term outcomes. A retrospective analysis of the database was performed, and 213 interventions performed in symptomatic patients were found. We identified 2 subgroups of patients: patients with stable neurological symptoms (not recent transient ischemic attack (TIA) or stable major disabling stroke, stable group, and 157 patients) and patients with unstable neurological symptoms (recent TIA, crescendo TIAs, stroke in evolution, acute/recent minor stroke, unstable group, and 56 patients). Perioperative outcomes were analysed in terms of mortality, major neurological events, and local or systemic complications The results were compared using the χ2 test; these were also analysed on the basis of the presenting symptom (isolated TIA, crescendo TIA, stroke in evolution, acute/recent minor stroke, stabilized stroke) and the timing of the intervention relative to the onset of the symptom. Long term results were analysed using the life-table analysis and Kaplan-Meier curves in terms of survival, stroke-free survival, absence of neurological symptoms, and absence of significant restenosis. RESULTS: Overall, 30-day stroke and death rate were 4.2%. (3.1% vs. 7%, P = 0.2). Two deaths occurred at 30 days, both in the stable group (mortality 1.2%, P = 0.4 compared to the unstable group), but no fatal strokes were recorded in the overall sample. No differences were found in terms of new perioperative neurological events and local complications between the 2 groups. We found a trend toward poorer perioperative results in patients operated on within 48 hr from the indexed event and in patients operated on for stroke in evolution or acute/recent stroke, whereas we found a trend toward better results in favour of patients operated on between 8 and 14 days (P = 0.08). The median duration of follow-up was 24.8 months (range 1-78); at 5 years we did not find significant differences in terms of survival and stroke-free survival rates between 2 groups. CONCLUSIONS: In our experience, carotid surgery in symptomatic patients provided satisfactory results, particularly in patients with stable neurological status. Among unstable patients, the rate of complications significantly increases, mainly among treated in the very early (<48 hr) period for stroke in evolution or acute/recent stroke. Once the perioperative risk is overcome, the results in the long-term setting are similarly good, both in stable and in unstable patients.

Total Iodine Contrast-free Strategy for the Endovascular Management of Abdominal Aortic Aneurysms in Chronic Kidney Disease Patients: A Pilot Study.

BACKGROUND: To retrospectively evaluate the feasibility and effectiveness of the endovascular treatment of patients with abdominal aortic aneurysm and chronic kidney disease (CKD) without the need for using iodinated contrast media throughout the diagnostic, therapeutic, and follow-up pathway. METHODS: A retrospective review of prospectively collected data concerning 251 consecutive patients presenting an abdominal aortic or aorto-iliac aneurysm who underwent endovascular aneurysm repair (EVAR) from January 2019 to November 2022 at our academic institution was performed in order to identify patients with feasible anatomy with respect to manufacturer's instructions for use and with CKD. Patients whose preoperative workout included duplex ultrasound and plain computed tomography for preprocedural planning were extracted from a dedicated EVAR database. EVAR was performed with the use of carbon dioxide (CO2) as the contrast media of choice, whereas follow-up examinations consisted of either duplex ultrasound, plain computed tomography, or contrast-enhanced ultrasound. Primary endpoints were technical success, perioperative mortality, and early renal function variations. Secondary endpoints were all-type endoleaks and reinterventions, midterm aneurysm-related and kidney-related mortality. RESULTS: Forty-five patients had CKD and were treated electively (45/251, 17.9%). Of them, 17 patients were managed with a total iodinated contrast media-free strategy and constituted the object of the present study (17/45, 37.8%; 17/251, 6.8%). In 7 cases, an adjunctive planned procedure was performed (7/17, 41.2%). No intraoperative bail-out procedures were needed. This extracted cohort of patients presented similar mean preoperative and postoperative (at discharge) glomerular filtration rate values, 28.14 (SD 13.09; median 28.06, interquartile range (IQR) 20.25) ml/min/1.73 m2 and 29.33 (SD 14.61; median 27.35, IQR 22) ml/min/1.73 m2, respectively (P = 0.210). Mean follow-up was 16.4 months (SD 11.89; median 18, IQR 23). During follow-up, no graft-related complications occurred in terms of either thrombosis, type I or III endoleaks, aneurysm rupture, or conversion. The mean glomerular filtration rate at follow-up was 30.39 ml/min/1.73 m2 (SD 14.45; median 30.75, IQR 21.93), with no significant worsening in comparison with preoperative and postoperative values (P = 0.327 and P = 0.856 respectively). No aneurysm- or kidney-related deaths occurred during follow-up. CONCLUSIONS: Our initial experience shows that total iodine contrast-free abdominal aortic aneurysm endovascular management in patients with CKD may be feasible and safe. Such an approach seems to guarantee the preservation of residual kidney function without increasing the risks of aneurysm-related complications in the early and midterm postoperative periods, and it could be considered even in the case of complex endovascular procedures.

Endovascular Reconstruction for Total Aorto-Iliac Occlusion.

OBJECTIVES: To analyze outcomes following endovascular treatment of total occlusion of the infrarenal aorta and aorto-iliac bifurcation in a multicenter Italian registry. METHODS: It is a multicenter, retrospective, observational cohort study. From January 2015 to December 2018, 1306 endovascular interventions for aorto-iliac occlusive disease were recorded in the vascular registry. For this analysis, only patients treated for total occlusion of the infrarenal aorta and aorto-iliac bifurcation were included. Early (<30 days) primary outcomes of interest were technical success and mortality. Late major outcomes were primary and secondary patency and freedom from conversion to open aortic surgery. RESULTS: A total of 54 (4.1%) patients met the inclusion criteria. Total percutaneous revascularization was possible in 41 (75.9%) patients and hybrid (endo plus open) intervention in 13 (24.1%) patients. The kissing-stent-graft technique was used in 45 (83.3%) cases, covered endovascular reconstruction of the aortic bifurcation (CERAB) in 5 (9.2%), and a unibody endograft deployed in 4 (7.4%). Technical success was 98.1% (n = 53). There were no episodes of intraoperative or perioperative vessel rupture. Conversion to open surgery was not necessary, and there were no in-hospital deaths. The median patient follow-up time was 16 months (interquartrile range [IQR], 6-27). The estimated primary patency rate was 95.8% ± 0.03 (95% confidence interval [CI]: 85.5-98.9) at 1 year, 91.4% ± 0.05 (95% CI: 76.2-97.2) at 2 years, and 85 ± 0.08 (95% CI: 64.5-94.6) at 3 years. Cox regression analysis demonstrated that sex (hazard ratio [HR]: 0.96; 95% CI: 0.15-6.23, p = 0.963), extent of the occlusion (HR: 0.28; 95% CI: 0.05-1.46, p = 0.130), calcium score (HR: 1.88; 95% CI: 0.31-11.27, p = 0.490), or type of endovascular reconstruction (HR: 0.80; 95% CI: 0.13-5.15, p = 0.804) did not affect primary patency. Secondary patency was 95.5% ± 0.04 (95% CI: 78.4-99.2) at 3 years. No patients required late conversion to open surgical bypass. CONCLUSIONS: Endovascular reconstruction for total occlusion of the infrarenal aorta and aorto-iliac bifurcation was successful using a combination of percutaneous and hybrid revascularization techniques. Estimated patency rates at 3 years of follow-up are promising and are unaffected by the extent of occlusion or type of revascularization.

Hybrid Surgical Approach to a Giant Post-Coarctation Aortic Aneurysm.

PURPOSE: To report a rare case of giant aortic coarctation (CoA)-related descending thoracic aneurysmal degeneration, complicated by an acute aortic dissection. CASE REPORT: A 57-year-old man referred with acute chest pain to the emergency department. A computed tomography angiography (CTA) revealed a CoA with a giant post-stenotic descending thoracic aneurysm (14 cm) and a concomitant left subclavian artery (LSA) aneurysm, complicated by an acute type B aortic dissection. A single-stage hybrid procedure was planned in an urgent setting. Initially, a left common carotid-to-left subclavian artery (LCCA-LSA) bypass was performed to gain a suitable proximal landing zone, the procedure was then completed with 3 thoracic endografts and 1 aortic dissection stent through a percutaneous femoral approach. The patient was discharged in postoperative day 8th without complications; the CTA performed at 1 month demonstrated patency of supra-aortic and visceral vessels, dilation of CoA site and exclusion of the false lumen. CONCLUSIONS: CoA is a congenital malformation rarely found in adults that may represent a challenge for the surgeon, especially when combined with a complication like an acute aortic dissection. This case shows that a hybrid approach is a safe and feasible treatment option even in such complex anatomies.

Results of Iliac Branch Devices in Octogenarians Within the pELVIS Registry.

Purpose: To evaluate if the elderly could benefit from the implantation of iliac branch devices (IBDs) to preserve the patency of the internal iliac artery (IIA) in aneurysms involving the iliac bifurcation. Materials and Methods: From January 2005 to April 2017, 804 patients enrolled in the pELVIS registry underwent endovascular aneurysm repair with 910 IBDs due to aneurysmal involvement of the iliac bifurcation. Among the 804 patients, 157 (19.5%) were octogenarians (mean age 82.9±2.5 years; 157 men) with 171 target IIAs for preservation. Outcomes at 30 days included technical success, death, conversion to open surgery, and major complications. Outcomes evaluated in follow-up were patency of the IBD and target vessels, type I and type III endoleaks, aneurysm-related reinterventions, aneurysm-related death, and overall patient survival. Kaplan-Meier analyses were employed to evaluate the late outcome measures; the estimates are presented with the 95% confidence interval (CI). Results: Technical success was 99.4% with no intraoperative conversions or deaths (1 bridging stent could not be implanted, and the IIA was sacrificed). Perioperative mortality was 1.9%. The overall perioperative aneurysm-related complication rate was 8.9% (14/157), with an early reintervention rate of 5.1% (8/157). Median postoperative radiological and clinical follow-up were 21.8 months (range 1-127) and 29.3 months (range 1-127), respectively. Estimated rates of freedom from occlusion of the IBD, the IIA, and the external iliac artery at 60 months were 97.7% (95% CI 96.1% to 99.3%), 97.3% (95% CI 95.7% to 98.9%), and 98.6% (95% CI 97% to 99.9%), respectively. Estimated rates of freedom from type I and type III endoleaks and device migration at 60 months were 90.9% (95% CI 87% to 94.3%), 98.7% (95% CI 97.5% to 99.8%), and 98% (95% CI 96.4% to 99.6%), respectively. Freedom from all cause reintervention at 60 months was 87.4% (95% CI 82.6% to 92.2%). The estimated overall survival rate at 60 months was 59% (95% CI 52.4% to 65.6%). Conclusion: IBD implantation in octogenarians provided acceptable perioperative mortality and morbidity rates, with satisfying long-term freedom from IBD-related complications and should be considered a feasible repair option for selected elderly patients affected by aneurysms involving the iliac bifurcation.

A propensity score-matched comparison of two commercially available iliac branch devices in patients with similar clinical and anatomic preoperative features.

OBJECTIVE: The objective of this study was to compare the perioperative and midterm results of Zenith Bifurcated Iliac Side (ZBIS; Cook Medical, Bloomington, Ind) and Gore Iliac Branch Endoprosthesis (IBE; W. L. Gore & Associates, Flagstaff, Ariz) iliac branch devices (IBDs) in treatment of dilated iliac bifurcations in patients with similar anatomic and clinical preoperative features. METHODS: Between July 2007 and May 2018, 190 IBDs were implanted at two high-volume Italian vascular and endovascular centers. Among the series, preoperative propensity score matching based on preoperative anatomic and clinical factors was performed, and two homogeneous groups were created: group 1, 35 Cook ZBIS IBD implants; and group 2, 35 Gore IBE devices. Early results were analyzed in terms of technical success, death, conversion to open surgery, and occurrence of major local and systemic complications. Follow-up results were analyzed in terms of patency of the IBD, freedom from type I and type III endoleaks, aneurysm-related reintervention, and aneurysm-related death. RESULTS: Technical success was achieved in all implants from both groups. Perioperative IBD-related complications and major complications occurred in one case from group 1 (P = .49). No perioperative mortality was recorded in the two groups. Mean postoperative follow-up was 46.7 months in group 1 (standard deviation, ± 36.3) and 20.8 months in group 2 (standard deviation, ± 15.9; P < .0001). None of the IBDs or target hypogastric arteries occluded during follow-up in this series. Estimated 36-month freedom from type I and type III endoleaks was 97% (standard error [SE], 0.03) in group 1 and 87% (SE, 0.09) in group 2 (P = .34; log-rank, 0.9). Estimated freedom from IBD-related reintervention was 97% (SE, 0.03) in group 1 and 93% (SE, 0.06) in group 2 (P = .81; log-rank, 0.05). The estimated rates of overall survival at 36 months from the IBD implantation were 95% (SE, 0.04) in group 1 and 88% (SE, 0.08) in group 2 (P = .03; log-rank, 4.7); freedom from aneurysm-related death was 100% in group 1 and 93% (SE, 0.06) in group 2 (P = .19; log-rank, 1.7). CONCLUSIONS: The propensity score-matched comparison between the Cook ZBIS and Gore IBE devices showed similar, satisfying perioperative and midterm results in the experience of two high-volume Italian vascular centers.

Outcomes From the Multicenter Italian Registry on Primary Endovascular Treatment of Aortoiliac Occlusive Disease.

Purpose: To report the results of endovascular treatment of iliac and complex aortoiliac occlusive disease (AIOD) in a multicenter Italian registry. Materials and Methods: A retrospective, multicenter, observational cohort study analyzed 713 patients (mean age 68±10 years; 539 men) with isolated iliac and complex aortoiliac lesions treated with primary stenting between January 2015 and December 2017. Indications for treatment were claudication in 406 (57%) patients and critical limb ischemia in 307 (43%). According to the TransAtlantic Inter-Society Consensus II (TASC) classification, the lesions were categorized as type A (104, 15%), type B (171, 24%), type C (170, 24%), and type D (268, 37%). Early (<30 days) endpoints included mortality, thrombosis, and major complications. Late major outcomes were primary and secondary patency and freedom from reintervention as estimated by Kaplan-Meier analysis; estimates are given with the 95% confidence intervals (CIs). Associations between baseline variables and primary patency were sought with multivariate analysis; the results are presented as the hazard ratio (HR) and 95% CI. Results: Technical success was achieved in 708 (99%) lesions; in-hospital mortality was 0.6% (n=4). The median follow-up was 11 months (range 0-42). The estimated primary patency rate was 96% (95% CI 94% to 97%) at 1 year and 94% (95% CI 91% to 96%) at 2 years. The estimated secondary patency was 99% (95% CI 97% to 99%) at 1 year and 98% (95% CI 95% to 99%) at 2 years. The estimated freedom from reintervention was 98% (95% CI 96% to 99%) at 1 year and 97% (95% CI 94% to 98.5%) at 2 years. Cox regression analysis demonstrated that the application of a covered stent was associated with an increased need for reintervention (HR 1.4, 95% CI 1.10 to 1.74, p=0.005). Chronic obstructive pulmonary disease was associated with decreased primary patency (HR 3.7, 95% CI 1.25 to 10.8, p=0.018). Conclusion: Endovascular intervention with primary stent placement for aortoiliac occlusive disease achieved satisfactory 2-year patency regardless of the complexity of the lesion. Almost all TASC lesions should be considered for primary endovascular intervention if suitable.

The Use of Pressure Recording Analytical Method in Patients Undergoing Endovascular Repair for Abdominal Aortic Aneurysm: The Impact on Clinical Decisions for the Appropriate Postoperative Setting and Cost-effective Analysis.

OBJECTIVE: To analyze the use of the Pressure Recording Analytical Method (PRAM), an hemodynamic monitoring system, in evaluating intraoperative and postoperative hemodynamic instability in patients undergoing endovascular repair for abdominal aortic aneurysm, and to evaluate if the decision to refer patients to a ordinary ward or to a Cardiac Step-Down Unit (CSDU) after the intervention on the basis of intraoperative hemodynamic monitoring could be more cost-effective. MATERIALS AND METHODS: After preoperative clinical evaluation, 44 patients were divided in this non-randomised study into two groups according to their postoperative destination: Group 1-ward (N=22) and Group 2-CSDU (N=22). All patients underwent monitoring with PRAM during the intervention and in the 24 postoperative hours, measuring several indices of myocardial contractility and other hemodynamic variables. RESULTS: According to the variability of two parameters, Stroke Volume Variation and Pulse Pressure Variation, patients were classified as stable or unstable. Unstable patients showed a significant alteration in several hemodynamic indices, in comparison to stable ones. According to the intraoperative monitoring, eight high risk patients could have been sent to an ordinary ward due to their stability, with a reduction in the improper use of CSDU and, consequently, in costs. CONCLUSIONS: Hemodynamic monitoring with PRAM can be useful in these patients, both for intraoperative management and for the choice of the more appropriate postoperative setting, possibly reducing the improper use of CSDU for hemodynamically stable patients who are judged to be at high risk preoperatively, and re-evaluating low surgical risk patients with an unstable intraoperative pattern, with a possible reduction in costs.

Surgical therapy of aorto-iliac aneurysm in a patient with congenital solitary pelvic kidney (CSPK): case report and literature review.

We report a case of a man with an Aorto-Iliac aneurysm and a congenital solitary pelvic kidney (CSPK). The maximum diameter of the aneurysm was 58 mm and the pelvic kidney was perfused by a single renal artery originating from the aortic bifurcation. A computed tomography scan was used for pre-operative planning and the patient underwent aorto-iliac aneurysm replacement with a Dacron graft. The renal artery was reimplanted on the Dacron right limb with a 'Carrel patch'. Several strategies were adopted to prevent renal ischemia such as sequential aortic cross clamping, selective cold perfusion of renal artery and a temporary Pruitt-Inahara shunt. The post-operative course was characterized by a transient increase in serum creatinine that did not require treatments and the patient was discharged after seven days. Congenital anomalies such as CSPK represent a challenge for the surgeon; however, the adoption of different intraoperative available strategies allowed to reduce possible complications.

Diagnosis and management of acute aortic syndromes in the emergency department.

Acute aortic syndromes (AASs) are deadly cardiovascular emergencies involving the thoracic aorta. AASs are relatively rare conditions, have unspecific signs and symptoms (including truncal pain, syncope, neurologic deficit and limb ischemia) and require contrast-enhanced tomography angiography (CTA) of the chest and abdomen for conclusive diagnosis and subsequent therapeutic planning. In the Emergency Department (ED), most patients with potential signs/symptoms of AASs are finally found affected by other alternative diagnoses. Hence, misdiagnosis and delayed diagnosis of AASs are major concerns. In critically ill patients, decision to perform CTA is usually straightforward, as exam benefits largely outweigh risks. In patients with ST-tract elevation on ECG, suspected primary ischemic stroke and in stable patients (representing the most prevalent ED scenarios), proper selection of patients necessitating CTA is cumbersome, due to concurrent risks of misdiagnosis and over-testing. Available studies support an algorithm integrating clinical probability assessment, bedside echocardiography and D-dimer (if the clinical probability is not high). Therapeutic management includes medical therapy for all patients including an opioid and anti-impulse drugs (a beta-blocker and a vasodilator), targeting a heart rate of 60 bpm and systolic blood pressure of 100-120 mmHg. Patients with AASs involving the ascending aorta are likely candidate for urgent surgery, and complicated type B AASs (severe aortic dilatation, impending or frank rupture, organ malperfusion, refractory pain, severe hypertension) necessitate evaluation for urgent endovascular treatment. For uncomplicated type B AASs, optimal medical therapy is the current standard of care.

Hybrid operating room applications in the increasingly complex endovascular era: the trump card of modern vascular surgery.

Hybrid operating room represents nowadays an important tool in the management of a constantly increasing number of complex surgical procedures which necessitate appropriate settings in order to be performed safely. We herein present the peculiarities and applications of such a versatile operating environment which is capable of guaranteeing the best performances in terms of equipment and imaging tools respecting the standards of asepsis that a simple angiographic room could not offer. In particular, we focus on its relevance in the field of complex vascular pathology, and on the importance of setting an appropriate management process in order to make the most of its potentialities without sacrificing the not negligible costs connected to it.

Extravascular risk factors in the prognostic evaluation for spinal cord injury during thoraco-abdominal aortic aneurysm exclusion: a case report.

BACKGROUND: The etiology of delayed-onset spinal cord injury (SCI) following endovascular repair of thoraco-abdominal aortic aneurysms (TAAA) is still unclear and may be related to multiple factors. Extravascular factors, such as lumbar spinal stenosis (LSS), may play a significant role in the selection of patient at risk of SCI. In this report we describe a case of paraplegia following thoracic endovascular aortic repair (TEVAR) in a patient suffering from severe and symptomatic LSS and undergoing staged endovascular repair of a TAAA. CASE PRESENTATION: A 70-year-old man was admitted to our department with an asymptomatic type III TAAA in previous open repair for abdominal aortic aneurysm. The patient complained of buttock and thigh claudication in the absence of defects in the pelvic perfusion; a spinal magnetic resonance angiography (MRA) showed a severe narrowing of the lumbar canal.. After 24 h from first-step procedure (TEVAR) paraplegia was detected. A cerebrospinal fluid (CSF) drainage was then placed with incomplete recovery. CONCLUSIONS: Stenotic damage to the spinal cord is thought to be the result of direct compression of the neural elements and ischemic disruption of arterial and venous structures surrounding the spinal cord. This comorbidity may constitute an additional anatomic risk factor in those patients currently recognized as prognostically associated to the development of SCI.

Patient-perceived outcomes of different anaesthetic techniques in classical surgical treatment of varicose veins of lower limbs.

AIM OF THE STUDY: To evaluate the effects of spinal or locoregional anaesthesia versus local tumescent anesthesia during traditional surgical treatment of saphenous reflux, in terms of pain and postoperative functional recovery. MATERIALS AND METHODS: From January to December 2014, 195 consecutive interventions of stripping of the greater saphenous vein for valvular incompetence were performed. In 114 cases spinal or locoregional anaesthesia was performed (group 1), in the remaining 81 cases local anaesthesia with the tumescence technique was carried out (group 2). All patients underwent an assessment of perceived pain by means of verbal rating scale before and at the end of surgery, at discharge and after a month. The times of recovery of ambulation during hospital stay and at the discharge were recorded and use of analgesic drugs during hospitalization and at home. At the end of the study, patients were asked to express their approval rating on the type of anaesthesia. RESULTS: Patients in group 2 experienced mild to moderate intraoperative pain more frequently than patients in group 1 (p<0.001), while patients in group 1 had more mild adverse anaesthesia-related events than patients in group 2. Patients in group 2 had faster recovery of ambulation and earlier discharge than patients in group 1.Thirty-day results were similar in the two groups; however, patients in group 2 had a higher degree of satisfaction than patients in group 1 with regard to the type of anaesthesia (p<0.001) CONCLUSIONS: Both locoregional and local tumescent anaesthesia are effective and well accepted by the patients, with similar intra-hospital and 30-day results.
