Abstract
BACKGROUND Popliteal artery aneurysms (PAAs) need urgent treatment in case of acute thrombosis, distal embolization, or rupture. Few data are available in the literature about the treatment results in these scenarios. The aim of the present study was to evaluate an 11-year multicenter experience in the urgent treatment of PAAs. METHODS All symptomatic PAAs surgically treated in two vascular centers between 2010 and 2021 were retrospectively analyzed. In the postoperative period periodical clinical and Duplex-Ultrasound evaluation were performed. The evaluated endpoint was the outcome of urgent PAAs treatment according to their clinical presentation. Statistical analysis was performed by Kaplan-Meier log-rank evaluation and multivariable Cox regression tests. RESULTS Sixty-six PAAs needed an urgent repair. Twelve (18%) patients had a PAA rupture and 54 (82%) had an acute limb ischemia (ALI) due to either distal embolization or acute thrombosis. Patients with ALI underwent bypass surgery in 51 (95%) cases, which was associated with preoperative thrombolysis in 18 (31%) cases. A primary major amputation was performed in 3 (5%) cases. The mean follow-up was 52 ± 21 months with an overall 5-year limb salvage of 83 ± 6%. Limb salvage was influenced only by the number of patent tibial arteries (pTA) [5-years limb salvage 0%, 86 ± 10%, 92 ± 8% and 100% in case of 0, 1, 2 or 3 pTA, respectively (P = .001)]. An independent association of number of pTA and limb loss was found [hazard ratio (HR): 0.14 (95% confidence interval (CI) 0.03-0.6), P = .001]. Overall 5-year survival was 71 ± 7%. Ruptured PAAs were associated with lower 5-year survival compared with the ALI group (48 ± 2% vs. 79 ± 7%, P = .001). The number of pTA (33 ± 20%, 65 ± 10%, 84 ± 10% and 80 ± 10% for 0, 1, 2 and 3 pTA, respectively, P = .001) and the thrombolysis (94 ± 6% vs. 62 ± 10%, P = .03) were associated with higher survival in patients with ALI. There was an independent association of number of pTA and long-term survival [HR 0.15 (95% CI 0.03-0.8), P = .03]. CONCLUSIONS PAA rupture is the cause of urgent PAA treatment in almost one fifth of cases, and it is associated with lower long-term survival. ALI can benefit from thrombolysis, and long-term limb salvage and survival are associated with the number of pTA.

Comparisons of outcomes of open surgery versus endovascular intervention for thrombotic popliteal artery aneurysm with acute lower limb ischemia: a systematic review. BMC Surg 2022; 22:398. [PMCID: PMC9673418 DOI: 10.1186/s12893-022-01843-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Accepted: 11/08/2022] [Indexed: 11/21/2022] Open
Abstract
Background Thrombotic popliteal artery aneurysm (PAA) with acute lower limb ischemia (ALI) is a serious disease leading to amputation. The choice of emergency procedures is not clearly defined, and the difference in therapeutic efficiency between open surgery and endovascular intervention is still unclear. Method We conducted a comprehensive search through PubMed, Wiley Online Library and ScienceDirect. According to the predefined inclusion and exclusion criteria, eligible articles were screened out, and all relevant data were extracted for further analysis. Our study was designed and developed based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guideline. We critically assessed all included articles by Joanna Briggs Institute (JBI) Critical Appraisal Checklists and the Methodological Index for Non-Randomized Studies (MINORS). Result A total of 29 articles (1338 patients/1387 limbs) were included in the study. After a 1-year follow-up, the primary patency rate of the open surgery group was significantly lower than that of the endovascular intervention group (72.65 vs. 81.46%, P = 0.004), but without significant difference in the secondary patency rate (86.19 vs. 86.86%, P = 0.825). The limb salvage rate of the open surgery group was also significantly lower (83.07 vs. 98.25%, P < 0.001). After the 2-year follow-up, the primary patency rate of the open surgery group was still significantly lower (48.57 vs. 59.90%, P = 0.021). Conclusion The outcome of endovascular intervention was better than that of open surgery especially in the 1-year limb salvage rate and primary patency rate at the 1-year and 2-year follow-ups.

Abstract
BACKGROUND Acute Compartment syndrome (ACS) with subsequent need for fasciotomy is a serious and insidious complication after revascularization for acute lower limb ischemia (ALI). The development of ACS during endovascular catheter directed thrombolysis is particularly difficult to identify. The aim was to identify the incidence, predisposing factors, wound treatment, and outcome in terms of amputation and survival for patients presenting with ALI that develop ACS during catheter directed thrombolysis. Patients who did not develop ACS after thrombolysis were analyzed as controls. METHODS Descriptive retrospective analysis of prospective databases from two large tertiary-referral vascular centers. Patients with ACS after thrombolysis for ALI between 2001-2017 were analyzed. RESULTS Seventy-eight cases and 621 controls were identified. Mean age was 72 years and 30 (38.5%) were women in the ACS group. Patients that developed ACS presented with significantly more severe preoperative ischemia. With 38.5% having Rutherford 2b classification as compared to 22.7 % in the control group (P = 0.002). Occluded popliteal artery aneurysms were also associated with a higher incidence of ACS (P = 0.041). Treatment of the fasciotomy wound was most commonly treated with regular wound dressing in 45 (58%) of cases, while wound dressing and foot pump and vacuum assisted closure were used in 14 (18%) and 19 (24%) respectively. These differing approaches did not affect the number of wound infections and amputations, which was similar regardless of treatment type. Vacuum assisted closure was associated with a higher degree of skin graft closure (P = 0.001). The median time to complete wound closure was 10 days. One year after thrombolysis, the major amputation rate in the ACS group was 31% as opposed to 17% in control group, P = 0.003. Mortality measured at 16.7% and 15.3%, respectively, P = 0.872. Amputation-free survival in the ACS group was 62% vs. 73% in the control group, P = 0.035. These differences level out, however, when applying long-term analysis of amputation-free survival in Kaplan-Meier analysis (log-rank 0.103). CONCLUSIONS Patients that developed ACS during endovascular CDT presented with a more severe pre-operative ischemia, more occluded popliteal artery aneurysms and had a higher amputation rate during the first year, compared to controls. The development of ACS during endovascular treatment of ALI with thrombolysis is not uncommon and warrants both clinical awareness and rapid treatment.

Abstract
BACKGROUND The treatment of patients with thromboembolic symptoms due to a popliteal artery aneurysm (PAA) is still controversial with poor results in terms of primary patency. The aim of our pilot study was to evaluate whether improving the outflow with an endovascular pretreatment consisting in thromboaspiration and angioplasty could positively ameliorate the primary patency of the subsequent femoropopliteal (FP) bypass in symptomatic patients with at least one below the knee (BTK) patent vessel. METHODS This is a single-center pilot case-control study that involves patients treated at the Vascular and Endovascular Surgery Unit of Udine, Italy, from January 2015 to November 2019. The inclusion criteria were the presence of thromboembolic symptoms due to PAA distal embolization, associated with the presence of a patent PAA >20 mm and a poor runoff (no more than one patent BTK artery). The case group was treated in a two-step approach: the first step consisted in thromboaspiration followed by BTK angioplasty, when appropriate, and the second one consisted in performing the surgical FP bypass. The control group moved on directly to the open surgical intervention. RESULTS The case group was composed of 11 patients, 10 males and 1 female, with a mean age of 69.3 ± 10.8 years. The mean PAA dimension was 32.6 ± 9.9 mm. Particularly, 9 patients were operated on through the medial vascular approach and 2 through the posterior one. The grafts used were 10 polytetrafluoroethylene (PTFE) and 1 great saphenous vein (GSV) in situ. The control group was composed of 11 male patients with a mean age of 75.5 ± 8.7 years, and the mean PAA dimension was 29.8 ± 13.4 mm. All the FP bypasses were approached medially, and the materials used were 10 PTFE and 1 reversed GSV. The median follow-up was 31.5 ± 12.6 months. Primary patency in the case group was 72.7% within one year; on the contrary, it was 27.3% in the control group. The amputation rate was 0% in the case group, 27.3% in the controls. By comparing the 2 groups, we found a higher and significant risk (P = 0.0261) of early FP bypass occlusion and major limb amputation in the control group. CONCLUSIONS This pilot study shows encouraging results; the endovascular approach is a safe and repeatable procedure which, improving the runoff in thromboembolic symptomatic PAA, seems to guarantee a better FP graft primary patency.

Abstract
The present study aimed to clarify the current status, therapeutic strategy, and 1-year outcome in acute limb ischemia (ALI) patients in Japan. The EnDOvascular treatment (Edo) registry database includes 324 patients from 10 institutes who were registered between November 2011 and October 2013. A total of 70 ALI patients (mean age 74.0 years) from the Edo registry database were enrolled in this study. Of the 70 included patients, 72.9% were male and 35.7% had embolism. Of patients, 38.6%, 42.9%, and 18.6% underwent EVT, surgery, and hybrid thrombectomy, respectively, in primary revascularization strategy. Limb ischemia was categorized into four classes at initial evaluation: SVS/ISCVS class I (n = 13, 18.6%), SVS/ISCVS class IIa (n = 36, 51.4%), SVS/ISCVS class IIb (n = 21, 30%), and SVS/ISCVS class III (n = 0, 0%). Three patients with SVS/ISCVS class IIb limb ischemia developed myonephropathic metabolic syndrome. No catheter-directed thrombolysis was employed as a primary revascularization strategy. The 1-year rates of all-cause death, major amputation, and a composite of perioperative death or major adverse limb event were 28.6%, 5.7%, and 40.0%, respectively. Lower age, male sex, dyslipidemia, high estimated glomerular filtration rate, high albumin level, and low C-reactive protein level were independent positive predictors of all-cause death. In this registry, SVS/ISCVS class IIa ALI was predominant. Approximately 40% of primary revascularization strategy was surgery and EVT, followed by hybrid therapy. All-cause death and major amputation rates at 1 year were less than 30% and 6%, respectively.

Abstract
OBJECTIVE Acute lower limb ischaemia (ALI) as a result of popliteal artery aneurysm (PAA) thrombosis represents a significant problem. The aim of this study was to investigate outcome of intra-operative intra-arterial thrombolysis in the treatment of acute ischaemia due to PAA thrombosis in terms of major adverse limb events (MALE), overall survival, and intrahospital complications, especially those associated with bleeding. METHODS A total of 156 patients with Rutherford grade IIa and IIb acute ischaemia resulting from PAA thrombosis were admitted between 1 January 2011 and 1 January 2017. The patients were divided into two groups, those who underwent additional treatment with intra-operative intra-arterial thrombolysis (20 patients), and those who did not (136 patients). By using covariables from baseline and angiographic characteristics, a propensity score was calculated for each patient. Each patient who underwent intra-operative thrombolysis was matched to four patients from the non-thrombolysis group. Thus, comparable patient cohorts (20 in the thrombolysis and 80 in the non-thrombolysis group) were identified for further analysis. The primary end point was MALE and the secondary endpoint all cause mortality. RESULTS After a median follow up of 55 months, the estimated MALE rate was significantly lower in the thrombolysis group (30% vs. 65%, chi square = 10.86, p < .001, log rank test). Also, patients in the thrombolysis group had a significantly lower mortality rate (20% vs. 42.65%, chi square = 3.65, p = .05, log rank test). The thrombolysis group had wound/haematoma related interventions performed more commonly (25% in thrombolysis vs 8%, in non-thrombolysis group), but the difference was not significant (p=.013). There were no cases of major (intracranial and gastrointestinal) bleeding in either group. CONCLUSION The data suggest that intra-operative thrombolysis in the treatment of selected patients with ALI due to PAA thrombosis has long term MALE and overall survival benefits, without a significant risk of major, life threatening bleeding complications.

Abstract
Popliteal artery entrapment syndrome (PAES) is a rare cause of intermittent claudication in young patients. Unlike the atherosclerotic and degenerative etiologies typically associated with arterial disease, PAES is primarily of anatomic origin. PAES is rarely associated with aneurysmal disease. We present a case and subsequent surgical management of a 47-year-old male who experienced acute limb ischemia secondary to thrombosis of a popliteal artery aneurysm (PAA), who was found to have bilateral PAES and PAAs.

Abstract
Acute limb ischemia (ALI) is a rapid decrease in lower limb blood flow due to acute occlusion of peripheral artery or bypass graft, and in ALI not only limbs but also life prognosis will be poor unless quick and appropriate treatment is given. The etiology is broadly divided into embolism and thrombosis with various comorbidities. The symptoms of ALI are abrupt with pain, numbness, and coldness of lower limb, and paresthesia, contracture, and irreversible purpura will appear with the exacerbation of ischemia. Severity and treatment strategy should be determined based on physical findings and image findings. Considering life prognosis, limb amputation should be done without hesitation when the limb was diagnosed as irreversible. ALI can be treated by means of open surgical revascularization, endovascular, or hybrid approach with rapid systemic administration of heparin. In any cases, evaluating the lesions by intraoperative angiography and appropriate additional treatment are important. ALI is a serious disease requiring urgent treatment, and it is essential to promptly perform the best initial treatment that can be performed at each facility.

Abstract
Background Consensus is lacking regarding intervention for patients with acute lower limb ischaemia (ALI). The aim was to study amputation‐free survival in patients treated for ALI by either primary open or endovascular revascularization. Methods The Swedish Vascular Registry (Swedvasc) was combined with the Population Registry and National Patient Registry to determine follow‐up on mortality and amputation rates. Revascularization techniques were compared by propensity score matching 1 : 1. Results Of 9736 patients who underwent open surgery and 6493 who had endovascular treatment between 1994 and 2014, 3365 remained in each group after propensity score matching. Results are from the matched cohort only. Mean age of the patients was 74·7 years; 47·5 per cent were women and mean follow‐up was 4·3 years. At 30‐day follow‐up, the endovascular group had better patency (83·0 versus 78·6 per cent; P < 0·001). Amputation rates were similar at 30 days (7·0 per cent in the endovascular group versus 8·2 per cent in the open group; P = 0·113) and at 1 year (13·8 versus 14·8 per cent; P = 0·320). The mortality rate was lower after endovascular treatment, at 30 days (6·7 versus 11·1 per cent; P < 0·001) and after 1 year (20·2 versus 28·6 per cent; P < 0·001). Accordingly, endovascular treatment had better amputation‐free survival at 30 days (87·5 versus 82·1 per cent; P < 0·001) and 1 year (69·9 versus 61·1 per cent; P < 0·001). The number needed to treat to prevent one death within the first year was 12 with an endovascular compared with an open approach. Five years after surgery, endovascular treatment still had improved survival (HR 0·78, 99 per cent c.i. 0·70 to 0·86) but the difference between the treatment groups occurred mainly in the first year. Conclusion Primary endovascular treatment for ALI appeared to reduce mortality compared with open surgery, without any difference in the risk of amputation. Endovascular may save lives

Abstract
BACKGROUND Popliteal artery aneurysms (PAAs) are generally complicated by thrombosis and distal embolization, whereas rupture is rare. The aim of this study was to describe the clinical characteristics and outcome in a cohort of patients who had surgery for ruptured PAA (rPAA). METHODS Operations for rPAA were identified from the Swedish Vascular Registry, Swedvasc, 1987-2012. Medical records and imaging were reviewed. Comparison was made with patients treated for PAA without rupture. RESULTS Forty-five patients with rPAA were identified. The proportion with rupture among those operated on for PAA was 2·5 per cent. Patients with rPAA were 8 years older (77·7 versus 69·7 years; P < 0·001), had more lung and heart disease (P = 0·003 and P = 0·019 respectively), and a larger mean popliteal aneurysm diameter (63·7 versus 30·9 mm; P < 0·001) than patients with PAA treated for other indications. At time of surgery, 22 of 45 patients were already receiving anticoagulants, seven for concomitant deep venous thrombosis (DVT) in the affected leg. There was extensive swelling of the whole leg in 20 patients. In 27 patients, the initial diagnosis was DVT or a Baker's cyst. All patients underwent surgery, all but three by the open method. There were four amputations, all performed within 1 week of surgery. One year after surgery, 26 of the 45 patients were alive. Among these, the reconstructions were patent in 20 of 22 patients. CONCLUSION The diagnosis of rPAA is difficult, and often delayed. The condition affects old patients, who often are on anticoagulation treatment and have large aneurysms. The immediate surgical results are acceptable, but the condition is associated with a high risk of death within the first year after surgery.

Abstract
OBJECTIVES Ninety-five per cent of those operated on for popliteal artery aneurysm (PA) are men. Thus, PAs in women are difficult to investigate. The aim was to study the disease in women. METHODS Women treated for PA in 1987-2012, prospectively registered in the Swedish vascular registry, Swedvasc, supplemented by case records, were compared with the larger male cohort. Survival was determined through cross linkage with the National Population Registry. RESULTS 1509 patients (men and women), 1872 legs, were identified; of these 74 patients (4.9%) were women, 81 legs (4.3%). The median age was 70 years in women versus 69 in men. Twenty-nine centres operated on women (range 1-7 women/centre). There were no time trends in the proportion of women operated on (p=.5). Bilateral PA occurred in 9.5% of women and 27.0% of men (p=.002). For symptomatic aneurysms, there was a larger proportion of small aneurysms (<2 cm) among women than men (24% vs. 8%, p=.005), there was no such difference in asymptomatic aneurysms. Distribution between asymptomatic and symptomatic PA was 31% versus 69%, similar to men. The prevalence of concomitant aneurysms in the aorto-iliac and femoral arteries, and the frequency of presenting symptoms were similar compared with men. Three PA were ruptured (3.7%). Thrombolysis was used in 23 of 45 legs treated for acute ischaemia (51%). Eight legs were treated with endovascular stent grafts (9.8%), compared with 7.9% in men (p=.5). Seven legs were amputated (8.6%). Crude survival was similar to men. CONCLUSIONS PA is similar in women and men, but bilateral disease was less common in women and symptomatic PA were more often <2 cm in diameter. Women had the same survival as men, despite women generally having better life expectancy. Although the largest series ever published on women with PA, the sample size is small, making it prone to type II statistical error.

Abstract
Resumo Contexto Aneurismas de artéria poplítea (AAPs) correspondem a 70,00% dos aneurismas periféricos. A indicação cirúrgica é para aneurismas com diâmetros maiores que 2,0 cm ou sintomáticos. O tratamento é feito por técnicas cirúrgicas convencionais ou endovasculares. Esta última tem ganho muitos adeptos, mas ainda não há consenso estabelecido sobre sua indicação. Objetivo Apresentar a experiência da Divisão de Cirurgia Vascular e Endovascular do Hospital das Clínicas de Ribeirão Preto da Universidade de São Paulo no tratamento dos AAPs. Método Foram revisados casos de reparo convencional e endovascular de AAPs tratados nos últimos cinco anos, avaliando dados demográficos, comorbidades, indicação cirúrgica, complicações pré e pós-operatórias precoces e tardias, tempo de internação e de perviedade em até um ano. Resultados Foram realizadas no período dez cirurgias endovasculares (CE) e 21 cirurgias abertas (CA). O grupo CE teve maior frequência de comorbidades. Houve maior frequência de pacientes sintomáticos no grupo CA (85,00%) do que no grupo CE (40,00%). O Grupo CE apresentou menor número de complicações clínicas e cirúrgicas. A idade entre os grupos e o tempo de internação de cada grupo não apresentaram diferença estatística. A perviedade primária em um ano no Grupo CE foi de 80,00%, enquanto no Grupo CA foi de 75,00%. Conclusão O tratamento endovascular para AAPs apresenta bons resultados, em termos de perviedade com taxas de complicações aceitáveis, em pacientes com risco cirúrgico elevado e anatomia favorável, justificando, assim, a necessidade de mais estudos controlados para modificar a posição da técnica endovascular como uma terapia alternativa para casos selecionados.

Abstract
Abstract
Background
The risk of developing a new aneurysm after surgery for popliteal artery aneruysm (PAA) is not well known. The aim was to study this risk in a cohort of patients.
Methods
A total of 571 patients who had primary operation for PAA (717 legs) between 1987 and 2002 were identified from the Swedish Vascular Registry (Swedvasc). Of these, 190 patients were re-examined by ultrasonography after a median of 7 (range 2·9–18·7) years.
Results
The number of patients with at least one aneurysm in addition to the PAA was 108 (56·8 per cent) at the index operation and 131 (68·0 per cent) at re-examination. The overall number of aneurysms increased by 41·8 per cent, from 244 to 346. Among the 82 patients who had an isolated PAA at the index operation, 23 developed a new aneurysm; these patients tended to be older (P = 0·004). Bilateral PAA at the index operation was associated with a later development of abdominal aortic aneurysm (P = 0·004). Age (P = 0·004) and hypertension (P = 0·012) at the time of the index operation were associated with multianeurysm disease at any time. Six (4·3 per cent) of 138 legs treated by venous bypass grafts had developed a graft aneurysm by the time of re-examination. No normal arterial segment developed an aneurysm that required surgery within 3 years.
Conclusion
The development of new aneurysms was common in patients with a PAA; lifelong surveillance may be warranted.

Abstract
Management of popliteal aneurysms remains controversial. Debate continues as to when an asymptomatic popliteal aneurysm should be treated and, with concerns regarding the fate of a bypassed popliteal aneurysm and the advent of intravascular stents, what procedure is best. This paper reviews the history of popliteal artery aneurysm management with particular emphasis on treatment and results before the modern era of arterial reconstruction. The aim of treatment then was to induce thrombosis. Now it is to prevent thrombosis.

Abstract
BACKGROUND This study investigated the importance of surgical technique on long-term outcome after treatment of popliteal artery aneurysms (PAAs). METHODS Records from 571 patients (717 legs) primarily operated on for PAAs were identified in the Swedish Vascular Registry. Surgical approach, type of graft, and anastomotic and ligation techniques were studied. After mean 7.2 years (range, 2 to 18 years) information on amputation was obtained for all patients, and 190 patients were re-examined with ultrasound imaging. RESULTS The approaches used were medial (medial approach group, MAG) in 87%, posterior (PAG) in 8.4%, endovascular in 3.6%, and other in 1.4%. Primary patency at 1 year with venous and prosthetic grafts was 85% vs 81% in the PAG (P = .719) and 90% vs 72% in the MAG (P < .001). Sixty-three legs (8.8%) were amputated <or=1 year, and 80 (11%) had been amputated at re-examination or by the end of follow-up. The median time from operation to amputation of 17 legs amputated after 1 year was 3.1 years (range, 1.1 to 9.8 years). The frequency of late amputation was 3.7% (2/54) in the PAG and 2.6% (15/571) in the MAG. In a Cox regression model, age (odds ratio [OR] 1.06/year, P < .001), emergency procedure (OR 2.67, P < .001), and prosthetic graft (OR 2.02, P = .008) were independently associated with long-term amputation rate. The risk of expansion of the excluded PAA at re-examination was 33% in the MAG and 8.3% in the PAG (P = .014). It was not affected by the ligation technique used. CONCLUSIONS The risk of late amputation was higher with prosthetic grafts. Operation with a posterior approach decreased the risk of expansion.
