Current guidelines are based on a paucity of literature and registry data are lacking. This study reports on medium term outcomes of patients with diagnosed DCTD compared to those without DCTD who were included in the W.L. Gore Global Registry for Endovascular Aortic Treatment (GREAT). METHODS: Patients included in the GREAT registry who underwent treatment for any thoracic or abdominal aortic pathology were included and grouped according to the presence or absence of a DCTD. Baseline demographic and procedural data were collected as well as data relating to key outcomes within 5 years follow-up, including all-cause mortality, aortic-related mortality, reinterventions and serious adverse events (SAE). Multivariable Cox proportional hazards models were built to determine if any association existed between the presence of DCTD and any key outcomes. RESULTS: The analysis included 92 (1.9%) with DCTD and 4741 (98.1%) without DCTD. Patients with DCTD were more likely to be female (34.8% vs. 18.5%, P < .0001) and younger (66.8 [15.1] vs. 71.7 [10.3] years, P = .013) than those without DCTD. They were also more likely to have had prior aortic intervention (22.8% vs. 13.9%, P = .015) and an associated branch vessel procedure with the index operation (30.3% vs. 18.6%, P = .005). The majority of reinterventions in both groups occurred within the first 2 years and multivariable models demonstrated that the presence of DCTD was not predictive of all-cause mortality, aortic-related mortality, reinterventions or SAE within 5 years. CONCLUSIONS: Within the limitations of registry data, this work demonstrates the medium term safety and durability of endovascular stent-grafts across a spectrum of aortic pathology in some patients with DCTD. More work is required to determine the applicability of these findings to specific sub-types of DCTD and aortic pathology.

Endovascular aortic repair (EVAR) has become standard treatment for abdominal aortic aneurysms and implementation of an early recovery program is warranted. Postoperative urinary retention (POUR) remains a problem lending to longer hospital stays and patient discomfort. We aim to demonstrate the utility of monitored anesthetic care (MAC) plus local anesthesia as a modality to minimize urinary retention following EVAR. METHODS: Single-center retrospective review from January 2017 to March 2020 of all patients undergoing standard elective EVAR under general anesthesia or MAC anesthesia. Local anesthetic at vessel access sites was used in all patients under MAC. Ruptured pathology and female sex were excluded from analysis. Patient characteristics, operative details, prostate measurements, and outcomes were abstracted from the electronic medical record. Urinary retention was defined as any requirement of straight catheterization, urinary catheter replacement, or discharge with urinary catheter. Chi square tests and logistic regression were used to determine predictors associated with POUR and increased hospital length of stay. RESULTS: Among 138 patients who underwent EVAR, eight (5.8%) were excluded due to ruptured pathology. Of the cohort, 113 (86.9%) were male with mean age of 73 years. Excluding female patients, 63 (55.8%) male patients underwent general anesthesia and 50 (44.3%) underwent MAC. Male patients under general anesthesia were more likely to have intra-operative urinary catheter placement when compared to MAC (82.5% vs. 36%, respectively; P < 0.001). POUR was identified in 17 patients (13.1%) of the entire study population with 15 events (88.2%) occurring in males. Excluding patients who were admitted to the ICU, twenty-two (19.5%) male patients stayed past postoperative day (POD) one, of which those who developed POUR were more likely to experience compared to those without POUR (45.6% vs. 9.7%, respectively; P = 0.001). On multivariable analysis, male patients who received MAC had a lower risk of developing POUR (OR 0.09, 95% CI 0.02-0.50). POUR was not associated with elective urinary catheter placement nor with pre-existing conditions such as diabetes, urinary retention, benign prostatic hypertrophy (BPH), or use of BPH medications. Additionally, neither prostate size nor volume was associated with developing POUR among male patients. CONCLUSION: MAC plus local anesthesia is associated with decreased rates of POUR after elective EVAR in male patients. ERAS pathways during elective EVAR interventions should implement MAC plus local anesthesia as an acceptable anesthetic option, where appropriate, in order to reduce urinary retention rates and subsequently decrease hospital length of stay in this patient cohort.

    查看更多>>摘要：Introduction: Aortic neck dilation post endovascular aneurysm repair (EVAR) has been implicated in the long-term development of endoleak and the subsequent re-intervention. Optimal endograft sizing is a vital aspect to successful repair. This study looked at percentage of graft oversizing as well as type of fixation on aortic neck dilation. Methods: We retrospectively evaluated all EVARs completed at Loyola's University from 2006 to 2015 after IRB approval. Patients without follow-up scans within a year were excluded. We collected demographics, comorbidities, graft type, size, aortic neck diameter, maximum sac size diameters from the pre-operative and follow-up scans. We reviewed and collected data on 432 patients but analyzed 154. We measured the largest aortic diameter on axial images 1 cm above and 1 cm below the lowest renal artery. Change in supra and infrarenal aortic measurements were evaluated by calculating the mm difference from each scan compared to the pre-operative scan. Linear mixed effects models were used to estimate patients' mean differences over time. Results: We compared three groups of neck fixation grafts. Those with active suprarenal fixation had a significant change in suprarenal aortic diameter at four-year follow-up (1.86 mm, CI:0.65-3.06), compared to those with active infrarenal (0.22 mm, CI: -0.67 to -1.11) or passive suprarenal fixation (1.52 mm, CI: -0.11 to -3.15) (Fig. 1). Those with active suprarenal fixation were the only ones to have significant increase in suprarenal aortic diameter (P = 0.0026). Degree of oversizing was also divided into three groups. Oversizing by <10% had less impact on the suprarenal aorta than >15% oversizing at 4 years (0.41 mm, CI: -0.31 to -1.14 vs. 3.26 mm, CI: 1.63-4.88, P < 0.001) (Fig. 2). Oversizing had a more pronounced effect on the infrarenal aorta: 3.01 mm, CI: 2.18-3.83; 5.95 mm, CI: 3.26-8.64; and 5.05 mm, CI: 3.41-6.69 for <10%, 10-15%, and >15% oversizing at four years, respectively. Conclusion: Stent-grafts with active fixation below the renal arteries as well as oversizing by <10% seem to have the least effect on aortic neck dilation over time. These factors should be considered when performing EVARs, as aortic neck dilation could lead to endoleak and need for further intervention. Further research defining the optimal stent-graft type, self-expanding versus balloon expandable, type of fixation and degree of oversizing.

    查看更多>>摘要：Background: Thoraco-abdominal endovascular aortic repair (TA-EVAR) can be associated with platelet depletion (PD); the present study aims to evaluate PD incidence after TA-EVAR and to investigate its possible predictors and its influence on hemorrhagic complications and mortality. Methods: A retrospective analysis of all TA-EVAR from 2010 to 2021 was performed to identify patients with PD, (reduction > 60%). Spontaneous hemorrhages considered were: intracranial or any hemorrhages requiring surgery. Risk factors for PD, correlation with hemorrhagic complications and 30-day mortality were investigated by uni/multivariate analysis. Results: A total of 158 TA-EVAR were considered, 35(22%) female, 86(54%) extended thoracourgent treatment (symptomatic/ruptured). PD was identified in 42 (27%) patients and correlated transfusion > 3 units and staged procedure at the univariate analysis. The multivariate analysis confirmed a significant correlation between PD and thrombus-free aortic lumen > 50mm, urgent treatment, blood transfusion > 3 units and staged procedure (odds ratio [OR]: 2.5 (95% confidence interval [CI] 1.03-7.0), P = 0.04, OR 3.2 (95% CI 1.01-8.6), P = 0.03, OR 3.16 (95% CI 1.23-7.7), P = 0.03 and OR 2.71 (95% CI 1.2-6.2), P = 0.04, respectively). Overall, 13 hemorrhagic complications occurred (8 intracranial and 5 peripheral); PD was associated with higher risk of hemorrhagic complications (9/42 - 21% vs. 4/116 - 3%, OR: 7.6 [95% CI: 2.2- 26.3], P = 0.001) and a higher risk of 30-day mortality in elective cases 4/25 - 16% vs. 3/101 - 3%, OR: 6.2 (95% CI: 1.3-29.8), P = 0.03. Conclusions: PD is a relatively common event after TA-EVAR and is associated with thrombusfree aortic lumen > 50mm, urgent treatment, blood transfusion > 3 units and staged procedure. Hemorrhagic complications and mortality are increased under these circumstances.

    查看更多>>摘要：Coronavirus disease 2019 (COVID-19) has been widely reported to be associated with increased risk of Venous Thromboembolism, both deep vein thrombosis (DVT) and pulmonary embolism. A rare and extreme manifestation of DVT is Phlegmasia cerulea dolens, characterized by poor tissue perfusion due to marked limb swelling which can progress to limb and life-threatening venous gangrene. We report the case of a 53-year-old man with severe SARS-CoV2 pneumonia who developed acute iliofemoral DVT leading to acute limb ischemia due to Phlegmasia cerulea dolens. The patient underwent successful emergent fasciotomy and mechanical thrombectomy with removal of extensive thrombus burden and restoration of normal venous circulation. Our case highlights the importance of clinical vigilance and early implementation of therapeutic interventions to avoid adverse outcomes in patients who develop SARS-CoV2 induced Venous Thromboembolism complications.

    查看更多>>摘要：Background: At our institution, we adopted routinely ultrasound guided approach for all percutaneous procedures. The objective of this study was to describe the predictors of access site failures (ASFs) in patients undergoing percutaneous aorto iliac revascularization and to also evaluate whether other factors such as time period or different vascular devices may influence outcomes in terms of ASFs. Methods: We reviewed all consecutive percutaneous revascularizations performed for aortoiliac occlusion or stenosis at our institution from 2011 to 2020. All procedure were performed using an ultrasound (US) guided common femoral access. The primary outcome was ASFs, defined as bleeding or groin hematomas that required transfusions; pseduoaneurysm (diagnosed by US); retroperitoneal hematoma; artery laceration or ruptured (diagnosed intraoperatively); and thrombosis. Multivariable logistic regression was used to determine predictors of ASFs. Results: A total of 502 femoral arteries were accessed under DUS guidance with no failure in sheath placement. Technical success was achieved in 498 of 502 procedures (99.2%). ASFs occurred in 21 patients (7%); but year of procedure appear to be associated with an excess of ASFs as rates were different between the first and second period of the study (10.9% vs. 4.8%, P = 0.04). Results of multivariable logistic regression model indicated that independent predictors of ASFs were common femoral artery (CFA) calcification peripheral artery calcium scoring system (PACCS) grade (odds ratio [OR], 8.7; 95% confidence interval [CI], 5.5-13.7), and CFA diameter (OR, 0.46; 95% CI, 0.25-0.85). Compared to patients with successful percutaneous access, ASFs resulted in longer post-op lengths of stay ( P = < 0.001). Conclusion: Percutaneous US guided access can be safely performed in patients undergoing endovascular procedures for aorto iliac revascularization with TASC C and D lesions. CFA calcification PACCS grade greater than 3 and smaller femoral vessel diameter are independent risk factors for ASFs.

    查看更多>>摘要：Objective: Peripheral artery disease (PAD) is often caused by atherosclerosis. However, causes other than atherosclerosis is often overlooked. Popliteal artery entrapment syndrome (PAES) and popliteal artery adventitial cystic disease (PACD) are two common nonatheromatous causes of claudication and critical limb ischemia. The purpose of this study is to present early results of treatment of PAES and PACD involving the lower limbs. Methods: From December 2019 to February 2021, 10 patients with PAES underwent surgeries, and 1 patient with PAES received conservative treatment. 2 patients with PACD underwent surgery. Patient data including age, gender, etiology of vascular pathology, diseased vessel, surgical method, and hemodynamic status were collected retrospectively. Results: The mean follow-up duration was 5.64 +/- 3.72 months (range, 1-12 months). All patients had their symptoms improved or resolved. The success rate of surgery was 100%, the rate of freedom from reintervention for any reason was 100%. There were no death, bleeding, embolism, or skin ulcers during late follow-up. Conclusions: PAES and PACD require early diagnosis and intervention, and early surgery may lead to good early- and mid-term results.

    查看更多>>摘要：Introduction: Current practice patterns favor endovascular treatment, resulting in fewer open procedures. When needed, greater saphenous vein and/or prosthetic conduits are considered the first choice for open vascular bypass. However, there is a cohort of patients in which these conduits are either not available or not suitable to address the surgical requirements. One alternative is to use femoropopliteal vein (FPV), an often-overlooked conduit. We report on the contemporary use of FPV in a tertiary vascular institution. Methods: All patients who underwent FPV harvest, as defined by CPT code 35572, between 2005 and 2019 were identified. Patient demographics (sex, age, baseline laboratory values, medical co-morbidities), indication for use of FPV, complications specific to vein harvest, operative details, post-operative course, and outcomes were recorded. Results: Ninety patients had harvest of FPV for creation of 123 conduits. In this study, a conduit was defined as a segment of vein used to perfuse a distinctly separate vascular bed. We identified four cohorts in which FPV was used: aorto-iliac reconstruction in 38 patients for infected graft (19), occlusive disease (8), aortitis (5), mycotic aneurysm (5), and malignancy (1); peripheral artery revascularization in 26 patients for ilio-femoral reconstruction (15), femoropopliteal reconstruction (4), upper extremity/cerebrovascular reconstruction (6), and coronary bypass (1); mesenteric revascularization in 20 patients for acute or acute on chronic ischemia (12), chronic ischemia (7) or aneurysm (1); and dialysis access in 6 patients. There was a high incidence of preexisting comorbid conditions in all groups, but most notably those patients who underwent aortoiliac reconstruction. Harvest-related or conduit-related complications included compartment syndrome, graft-associated hemorrhage, surgical site infection, and lymphatic complications. Primary graft patency at 3 years was 83% +/- 4% (aorto-iliac), 83% +/- 6% (peripheral), 100% (mesenteric), and 23% +/- 19% (dialysis access, P < 0.001). Conclusions: While use of FPV has potential significant harvest-related, conduit-related, or systemic complications, FPV is useful for a variety of needs, almost universally available, and durable. In the current era where endovascular approach is the focus, FPV should not be forgotten as a potential conduit that can be used for a variety of vascular reconstruction indications.
