Manunga J, Mirza A, Skeik N, Stanberry L, Jayarajan S, Sullivan TM. Comparative Long-term Outcomes of Patients with Aortoiliac Occlusive Disease Limited to Common Iliac Arteries Who Underwent Endarterectomy versus Bypass Grafting. Ann Vasc Surg 2020; 68:1-7. [PMID: 32474143 DOI: 10.1016/j.avsg.2020.05.043] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 05/07/2020] [Accepted: 05/08/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND The objective of this study was to compared outcomes of patients with aortoiliac occlusive disease (AIOD), limited to the common iliac artery, who underwent either aortoiliac thromboendarterectomy (AIE) or aortobiiliac bypass grafting (ABIB). METHODS A single-center, retrospective analysis of consecutive patients with AIOD who underwent either AIE or ABIB between 2010 and 2019 from a prospective database. Patients with disease extending to the external iliac or common femoral arteries were excluded. Data collected included demographics, cardiovascular risk factors, indication for surgery, preoperative and postoperative ankle brachial indexes (ABIs), estimated blood loss, major adverse events (MAEs), and long-term patency. The study end point was clinical success, defined as improvement in ABIs with resolution of symptoms. MAEs included return to the operating room for any reason, postoperative myocardial infarction, stroke, pneumonia, or venous thromboembolism. RESULTS Thirty-three patients, who met inclusion criteria, underwent repair for AIOD (AIE: 13; ABIB: 20) at our institution during this time. In both groups, there were more women than men (AIE: 11, ABIB: 10) with a mean age of 55 ± 7 years and 58 ± 6 years in the AIE and ABIB group, respectively. Indication for surgery included disabling claudication in 19 patients, ischemic rest pain in 13 patients, and tissue loss in one patient. No difference in cardiovascular risk factors or AIOD severity was noted between groups. Patients in the AIE group had slightly higher body mass index (30 ± 5 vs. 26 ± 6, P = 0.06). Two patients in each group required concomitant renal/mesenteric artery endarterectomy. One patient in the AIE group required bilateral femoral artery exposure and external iliac thrombectomy. MAEs (4 vs. 0) were higher in the ABIB group including, pneumonia in one patient, myocardial infarction in another, return to the operating room for evacuation of hematoma in the third and bypass graft thrombectomy with lower extremity angiography in the fourth patient. There were no differences in the intensive care unit or hospital length of stay between groups. Patients in both groups achieved return of normal ABI and complete resolution of their symptoms. At mean follow-up time of 43.4 ± 25.2 and 52.9 ± 35.4 months in the AIE and ABIB group, respectively, there was no symptomatic recurrence or need for reintervention while two patients in the ABIB group died of non-aortic-related issues. CONCLUSIONS Both procedures were safe, effective, and conferred high long-term primary patency with no need for reintervention in patients with AIOD limited to the common iliac arteries.

Abstract
OBJECTIVE The purpose of this study was to report our results of patients' characteristics, procedural complications, and long-term patency in treatment of isolated infrarenal aortic stenosis (IIAS). METHODS Forty symptomatic patients (28 female, 12 male; median age, 60 years [54.8-68 years]) with IIAS who underwent endovascular intervention between 2001 and 2017 were retrospectively analyzed. Patient, lesion, procedure, and balloon/stent characteristics were assessed. Follow-up included clinical status evaluation and color Doppler ultrasound examination. RESULTS The cause of IIAS was atherosclerosis in all patients. Twenty percent of the patients were younger than 50 years; 85% had hypertension, 80% were smokers, 38% had hyperlipidemia, 23% had diabetes mellitus, 15% were obese (body mass index ≥30 kg/m2), and 8% had chronic kidney disease. The median stenosis grade was 80% (70%-80%), and the median lesion length was 19.9 mm (13-29.4 mm). Severe calcification was present in 8% of the patients. Percutaneous transluminal angioplasty was performed in four cases (10%), whereas stenting was performed in 36 (90%). One complication, an aortic rupture requiring surgical repair, occurred. The median follow-up was 61 months (17-101 months). The primary patency rate was 100% at 6 months, 97% at 12 and 24 months, and 88% at 60 and 96 months. Restenosis developed in three patients (8%); reintervention was carried out in two cases (5%). CONCLUSIONS Endovascular therapy for IIAS provides a safe and effective long-term treatment strategy.

Abstract
Objective: The aim of this study was to evaluate the long-term results of aortic stent placement in patients with infrarenal aortic occlusive disease. Methods: Between April 1996 and May 2014, 34 patients with symptomatic infrarenal atherosclerotic aortic stenosis or subtotal aortic occlusion underwent percutaneous angioplasty with primary aortic stent implantation. There were 21 patients with Fontaine stage of the peripheral arterial disease (PAD) II, 5 patients with stage III, and 8 patients with stage IV. One patient withdrew informed consent and was excluded from further analysis. Results: Patients (n = 34, mean age: 62 ± 12 years) were followed for a mean period of 81 months. There were 2 procedure-related access-related complications. Six patients died during follow-up from non-procedure-related causes. Eight patients had late recurrence of symptoms during follow-up. Only in 2 cases, symptomatic recurrences were due to aortic in-stent stenosis (77 and 132 months after the primary stent implantation). Additionally, these 2 patients required therapy for PAD progression distal to the aorta. Five patients required further surgical or endovascular reconstruction for PAD progression distal to the aorta. In another case, clinical treatment failure was due to the progression of atherosclerotic lesion in the perirenal, nonstented part of the abdominal aorta. The mean estimated primary patency rate was 185.6 months (95% confidence interval: 161.3-209.8). Conclusion: Endovascular stent implantation is a safe and long-term effective strategy for the treatment of infrarenal aortic occlusive disease. In our study, the recurrence of symptoms was observed mainly due to atherosclerosis progression by multilevel disease with associated infrainguinal occlusive lesions but not to aortic in-stent restenosis. The prognostic advantage for this relatively young cohort of patients can be the possibility to repeat a percutaneous procedure with less technical difficulties when compared to surgical revision.

Abstract
Peripheral arterial disease (PAD) continues to grow in global prevalence and consumes an increasing amount of resources in the United States health care system. Overall rates of intervention for PAD have been rising steadily in recent years. Changing demographics, evolution of technologies, and an expanding database of outcomes studies are primary forces influencing clinical decision making in PAD. The management of PAD is multidisciplinary, involving primary care physicians and vascular specialists with varying expertise in diagnostic and treatment modalities. PAD represents a broad spectrum of disease from asymptomatic through severe limb ischemia. The Society for Vascular Surgery Lower Extremity Practice Guidelines committee reviewed the evidence supporting clinical care in the treatment of asymptomatic PAD and intermittent claudication (IC). The committee made specific practice recommendations using the GRADE (Grades of Recommendation Assessment, Development and Evaluation) system. There are limited Level I data available for many of the critical questions in the field, demonstrating the urgent need for comparative effectiveness research in PAD. Emphasis is placed on risk factor modification, medical therapies, and broader use of exercise programs to improve cardiovascular health and functional performance. Screening for PAD appears of unproven benefit at present. Revascularization for IC is an appropriate therapy for selected patients with disabling symptoms, after a careful risk-benefit analysis. Treatment should be individualized based on comorbid conditions, degree of functional impairment, and anatomic factors. Invasive treatments for IC should provide predictable functional improvements with reasonable durability. A minimum threshold of a >50% likelihood of sustained efficacy for at least 2 years is suggested as a benchmark. Anatomic patency (freedom from restenosis) is considered a prerequisite for sustained efficacy of revascularization in IC. Endovascular approaches are favored for most candidates with aortoiliac disease and for selected patients with femoropopliteal disease in whom anatomic durability is expected to meet this minimum threshold. Conversely, caution is warranted in the use of interventions for IC in anatomic settings where durability is limited (extensive calcification, small-caliber arteries, diffuse infrainguinal disease, poor runoff). Surgical bypass may be a preferred strategy in good-risk patients with these disease patterns or in those with prior endovascular failures. Common femoral artery disease should be treated surgically, and saphenous vein is the preferred conduit for infrainguinal bypass grafting. Patients who undergo invasive treatments for IC should be monitored regularly in a surveillance program to record subjective improvements, assess risk factors, optimize compliance with cardioprotective medications, and monitor hemodynamic and patency status.

Abstract
PURPOSE To report long-term outcomes of endovascular therapy (EVT) for aortoiliac bifurcation lesions. METHODS Patients enrolled in the multicenter REtrospective AnaLysis of Aorto-Iliac stenting (REAL-AI) registry in Japan were pooled. Of 2096 patients who underwent EVT for de novo aortoiliac disease between January 2005 and December 2009, 190 patients (148 men; mean age 70±9 years) had aortoiliac bifurcation lesions that were treated with stents, whose configuration (single, V, or kissing) and type (balloon-expandable or self-expanding) were subjected to regression analysis to determine any impact on primary patency along with other demographic, clinical, and lesion characteristics, including Trans-Atlantic Inter-Society Consensus II C/D classification. The primary endpoints were restenosis and target lesion revascularization (TLR). Secondary endpoints were all-cause death, major cardiovascular events, and major cardiovascular + limb events. RESULTS The overall complication rate was 6.3%, and 1- and 5-year primary patency rates were 87% and 73%, respectively. Over a mean follow-up of 31±15 months, there were 36 (19.0%) restenoses, 22 (11.6%) TLRs, and 4 (2.1%) reocclusions; stent fracture (2, 1.1%) and major amputation (2, 1.1%) were rare. Only female gender [adjusted hazard ratio (AHR) 4.26, 95% CI 1.89 to 9.71, p<0.001] and residual diameter stenosis (AHR 1.04, 96% CI 1.01 to 1.06, p=0.01) were independent predictors of primary patency. CONCLUSION Stenting for aortoiliac bifurcation lesions was found to be safe and effective. Neither stent configuration nor type appeared to affect vessel patency in true bifurcation lesions.

Abstract
Aortic rupture during endovascular procedures is a devastating complication that mandates expedient intervention. The present report describes a case in which endovascular treatment was used to successfully manage an aortic rupture following placement of a covered stent graft for severe infrarenal aortic stenosis. Successful management of this case was the result of the procedure being performed in an operating room under appropriate anesthesia and close hemodynamic monitoring. Bilateral common femoral arterial access and use of covered aortic stent grafts also contributed to a favourable outcome.

Abstract
We report a case of a 54-year-old woman presenting a symptomatic focal atherosclerotic abdominal aortic stenosis. Computed tomographic angiography allowed to study the lesion, the abdominal aorta and its main branches. The patient was treated via an endovascular approach using a covered stent. The postoperative course was uneventful and the patient was asymptomatic with a patent reconstruction after 18 months. Improvement in endovascular technology has totally modified the treatment of focal atherosclerotic abdominal aortic stenosis. However, many technical points remain to be determined including the necessity of systematic stenting, the type of stent to use, and the steps of the procedure.

Abstract
The management of coral reef lesions reported in this case study demonstrates the complementary and non-competing character of the open and endovascular treatment. The minimally invasive procedure of stent-optimized angioplasty seems to be advantageous as the primary therapy in selected cases. In the case of clinical deterioration the endovascular technique allows surgical reconstruction without significantly diminishing the result. Catheter-based techniques therefore remain an additional instrument for treatment in the hands of vascular surgeons which substantially broadens the range of therapy options for this disease entity.

Abstract
We report two cases of heavily calcified infrarenal aortic stenosis that were successfully treated by intravascular ultrasound- (IVUS)-guided stenting. Two middle-aged women visited our hospital due to intermittent claudication. Diagnostic arteriography revealed possible infrarenal aortic stenosis even though the findings were equivocal. IVUS demonstrated heavily calcified atherosclerotic lesions and allowed the accurate assessment of the types and extents of the lesions to be treated in both cases. The patients successfully underwent stent implantation according to the findings of IVUS. IVUS significantly contributed to the interventional successes.

Abstract
In this article, current evidence-based treatment recommendations for acute and chronic lower limb ischemia will be presented considering the varied possibilities of endovascular techniques and open surgical vascular strategies. Beside presentation of the different therapeutic possibilities, advantages of the combination of both techniques will be described. Despite the BASIL trial, there are no prospective randomised controlled trials comparing endovascular and open surgical interventions. Different therapeutic rules along the different vascular segments will be discussed for both acute and chronic peripheral arterial disease. Generally it can be stated that aortoiliac revascularization for chronic obstructions is increasingly being carried out by endovascular means or hybrid procedures using a minimally invasive femoral approach, whereas acute occlusions in this vascular segment are still treated with open surgical techniques (Fogarty balloon thrombectomy). In the infrainguinal region, endovascular therapeutic strategies are gaining favor. However, multilevel occlusions and long-segment obstructions in the femoral and popliteal segment are still treated by bypass procedures. Acute ischemia in the infrainguinal segment is increasingly treated with endovascular methods (local thrombolysis and percutaneous thrombectomy).

Abstract
Published in 2000, the TransAtlantic Inter-Societal Consensus (TASC) guidelines contained a new classification system for treatment of peripheral arterial disease. The classification was based upon response to intervention and was independent of technology and techniques. The goal of this system was to indicate the best form of treatment, endovascular (TASC A) or surgical (TASC D), for patients with lower-extremity arterial occlusive disease based upon highest levels of evidence in published reports. Those lesions without strongly supportive evidence, but with a greater likelihood of good response to endovascular (TASC B) or surgery (TASC C), were noted as critical issues requiring additional assessment. It was the intent of the TASC Working Group that this classification be periodically updated. Lesion location, length, calcification, and occlusion have each posed significant challenges to the successful and enduring endovascular treatment of peripheral arterial disease. Since 2000, vascular specialists have systematically addressed these variables with new technology and techniques to improve results. These improvements have been reflected in changes to lesions included in each category of the initial TASC classification system as listed in TASC II. This review provides an evidence-based rationale for these changes.

Abstract
OBJECTIVE To determine the safety and the long-term results of primary stent placement for localized distal aortic occlusive disease. DESIGN Retrospective observational study. PATIENTS AND METHODS From July 1998 to July 2005 17 patients (14 female and 3 men, mean age 57 years (39-80)) were treated for intermittent claudication. Five of these patients underwent additional endovascular treatment of focal iliac lesions. RESULTS Technical success defined as residual stenosis of less than 50% or a trans-stenotic systolic pressure gradient <10% was achieved in 14 of 17 (82%) patients. Major complications included dissection at the puncture site in one patient and thrombosis of additional iliac stents in another patient. Both of these complications were successfully treated. During a mean follow-up of 27 months (range 1-86), four patients had recurrence of symptoms due to in-stent restenoses (n=2), femoral (n=1) or iliac occlusion (n=1), respectively. By Kaplan-Meier analysis, primary aortic hemodynamic patency was 83% at 3 years. Secondary aortic hemodynamic patency was 100%. The primary clinical patency was 68% at 3 years. CONCLUSION Primary stent placement for distal aortic stenoses is an alternative to surgical treatment because of its high patency and relatively low complication rates.

MATERIALS AND METHODS A total of eight atherosclerotic stenoses and one occlusion of the infrarenal aorta (ie, midaortic syndrome) were treated with endoluminal stent placement after balloon angioplasty. Aortoiliac lesions were excluded. Technical success and patency were assessed. RESULTS Primary technical success in percutaneous transluminal angioplasty and subsequent stent placement was achieved in all patients. No complications occurred, and no morbidity was encountered. Primary clinical patency rates were 100% on all follow-up examinations. Long-term results with a mean follow-up of 110 months (range, 99-117 months) were recorded in seven patients; one patient had died and one was lost to follow-up. CONCLUSIONS In view of the excellent initial results and promising long-term follow-up data in a small series, stent placement after predilation in properly selected patients with isolated infrarenal aortic stenosis appears to be a promising, durable treatment. It should be considered as a primary method of treatment.

Abstract
PURPOSE To review the long-term results of primary stent placement in the distal aorta above the bifurcation. METHODS Fourteen patients (8 men; mean age 62 years, range 46-82) underwent primary stent implantation performed by an interdisciplinary radiosurgical team. In 10 patients, a long-term follow-up examination consisting of patient history, clinical examination, and duplex sonography was performed. The ankle-brachial index (ABI) for the posterior tibial artery was calculated on the basis of Doppler pressure measurements. RESULTS The clinical success rate at the first follow-up examination (mean 2.9 months, range 2.1-4.4) was 100% (n = 14). The mean baseline ABI of 0.64 +/- 0.12 had risen to 1.02 +/- 0.10 (p < 0.0001). At midterm follow-up (mean 22.8 months, range 14-42) in 12 patients, the ABI was 0.96 +/- 0.12 (p < 0.0001 versus baseline). At a mean 86 months (range 51-119) after stent treatment, the ABI in 10 patients was 0.90 +/- 0.20 (p < 0.0001 versus baseline). Over the long term, the clinical success rate was 70%. Deterioration was due to the progression of atherosclerosis distal to the aorta; duplex sonography showed no aortic restenosis or occlusion. CONCLUSION In view of the excellent long-term results in our small series, primary stent placement in focal abdominal aortic stenosis in properly selected patients is a durable treatment. In addition, the mortality and morbidity risks are markedly reduced compared with open surgery.

Abstract
OBJECTIVE To examine the safety and efficacy of endovascular management of isolated infrarenal aortic occlusive disease within our centre. DESIGN AND METHODS Retrospective analysis of all patients who underwent endovascular treatment of occlusive disease that is confined to the infrarenal aorta between September 1993 and November 2004. RESULTS Primary aortic stenting was carried out in 16 women and five men using self-expanding (12 patients) and balloon expanding stents to treat both occlusions (six) and stenoses (15). Indications included intermittent claudication (13), critical limb ischaemia (six), and distal embolisation (three). Significant postoperative complications within 30 days were noted in three, including one death. Fifteen patients completed 1-year follow-up with primary patency in 14 and secondary patency in the remaining patient. Clinical improvement was documented in all patients. CONCLUSION Primary stenting for occlusive disease isolated in the infrarenal aorta is relatively safe in selected patients with encouraging early follow-up results.

Abstract
PURPOSE To study the results including long-term follow-up obtained with endovascular treatment of patients with intermittent claudication who did not experience clinical improvement with conservative treatment. METHODS From January 1992 to January 2002, 62 of 1380 patients (4.5%) with intermittent claudication underwent endovascular treatment and were followed up for up to 120 months (mean 76 months). The variables analyzed were the functioning of the arterial segment undergoing the endovascular procedure, the evolution of the maximum walking distance, and incidence of related morbidity and mortality. RESULTS Fifty-two patients (84%) experienced no walking limitation after the procedure, and 6 patients (10%) improved but still exhibited some degree of limitation, for a total improved outcome of 94%. The patency rate was 82%. There was no intraoperative mortality. One primary failure and one immediate thrombosis occurred, and both were surgically corrected. Thrombosis of the treated artery occurred in 6 patients 12, 16, 25, 29, 62, and 66 months after the procedure. These patients started to experience intermittent claudication with a walking distance to onset that was similar to their presurgical distance to onset. During follow-up, a mortality rate of 12.9% (8 patients) was observed, 6 due to myocardial infarctions and 2 due cerebral infarction. Three patients underwent coronary bypasses 22, 36, and 55 months after the endovascular surgery, and 2 patients underwent coronary angioplasty after 6 and 26 months. The mean follow up period was 76 months (range 0-120 months). CONCLUSION This study shows that endovascular treatment of intermittent claudication brought about a lasting regression of the ischemic conditions in a significant number of patients, with excellent patency rates. It was concluded that this is a good alternative for selected patients, with low rates of complications and positive long-term results.

Abstract
From an initially simple concept, vascular stents have evolved into highly specialized instruments, and are poised to develop into sophisticated drug-delivery systems. Although primary research has mostly targeted the coronary circulation, newer generation stents, deliverable almost anywhere, retarding neointimal hyperplasia and thrombosis, and promoting endothelial overgrowth, will offer the next approximation of true vascular healing. This, in turn,promises to promote less invasive, safer, and finally durable endovascular solutions to current surgical problems.
