The Combination of Vacuum-Assisted Thromboaspiration and Covered Stent Graft for Acute Limb Ischemia due to Thromboembolic Complications of Popliteal Aneurysm. Ann Vasc Surg 2023; 89:232-240. [PMID: 36174918 DOI: 10.1016/j.avsg.2022.08.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2022] [Revised: 08/10/2022] [Accepted: 08/25/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND We present a standardized protocol of endovascular revascularization for patients with acute limb ischemia due to popliteal artery aneurysm (PAA) thromboembolic complication, based on the combination of vacuum-assisted thromboaspiration to improve tibiopedal outflow and covered stent graft to exclude the PAA. METHODS All patients with a diagnosis of PAA complicated by thromboembolic events undergoing total endovascular rescue were prospectively enrolled in a dedicated database from November 2018 to November 2021. To assess vessel patency, the TIPI (Thromboaspiration In Peripheral Ischemia) classification was used. The primary end point was the primary technical success (at least one tibial vessel with a TIPI flow of 2 or 3). The 30-day overall mortality and amputation rates were considered as secondary end points. Patients' overall survival, limb salvage, freedom from reocclusion and reinterventions were reported as secondary late outcomes using Kaplan-Meier method. RESULTS Seventeen male patients were enrolled with a mean age of 75.7 ± 9 years. Rutherford grading score was IIa in 52.9% (9/17) and IIb in 47.1% (8/17). PAA mean diameter was 37.4 ± 11.2 mm. All patients had tibial arteries involvement, and in 9 cases (52.9%) there was also the occlusion of the PAA. Mechanical thrombectomy with Indigo/Penumbra thromboaspiration system was used in all patients. PAAs were excluded using one or more VIABAHN covered endografts (range 1-3 pieces). Technical success was achieved in 94.1%. Fasciotomy was performed in 1 case (5.9%). Mortality and amputation rates at 30-day follow-up were respectively 0% and 5.9%. Survival rates at 6, 12, and 24 months were respectively 94.1%, 86.3%, and 67.9%. Secondary patency was achieved in all cases (100%). Freedom from reintervention was 80.4%, 65.8%, and 54.8% at 6-, 12-, and 24-month follow-up. Limb salvage was 88.2% at 6-, 12-, and 24-month follow-up, respectively. CONCLUSIONS Although preliminary, our experience of total endovascular rescue for complicated PAA with thromboembolic events highlighted promising rates of limb salvage at 30 days after intervention. The total endovascular approach seems able to maximize tibiopedal outflow offering an interesting strategy in limb salvage.

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
The Society for Vascular Surgery clinical practice guidelines on popliteal artery aneurysms (PAAs) leverage the work of a panel of experts chosen by the Society for Vascular Surgery to review the current world literature as it applies to PAAs to extract the most salient, evidence-based recommendations for the treatment of these patients. These guidelines focus on PAA screening, indications for intervention, choice of repair strategy, management of asymptomatic and symptomatic PAAs (including those presenting with acute limb ischemia), and follow-up of both untreated and treated PAAs. They offer long-awaited evidence-based recommendations for physicians taking care of these patients.

Abstract
Purpose We sought to evaluate the incidence of popliteal artery aneurysms (PAAs) in patients who have a diagnosis of abdominal aortic aneurysm (AAA). Methods It has been previously documented that patients with AAA have a greater incidence of PAA. During the past 11 years, 163 patients presented to the Vascular Laboratory at Harborview Medical Center with an AAA. Seventy-one (44%) of these patients had popliteal arteries evaluated using duplex ultrasound (Advanced Technology Laboratory 3000, 5000, 9000). The popliteal artery was measured in the anteroposterior and transverse diameters. A PAA was defined as an artery larger than 1.5 cm and/or an ectatic artery with thrombus present. Results Fourteen patients had a PAA; six patients (43%) had PAA bilaterally, for a total of 20 aneurysms. Nineteen (95%) aneurysms had thrombus present. Various interventional treatments were used: five limbs (25%) received an arterial bypass graft, two (10%) underwent amputation, and two (10%) received thrombolytic therapy Conclusions There is a high incidence of PAA in patients with AAA (19.7% in this series). Patients with a diagnosis of AAA should be screened for PAA and considered for elective repair to prevent the high rate of complications associated with these lesions.

Abstract
Uncommon diseases of the popliteal artery include cystic adventitial disease, popliteal artery entrapment syndrome (PAES) and popliteal artery aneurysm (PAA). Because all of these conditions may present with pain or intermittent claudication, imaging is crucial for differentiating them and directing management. Delayed diagnosis can lead to major complications, including acute limb ischemia. Our aim is to provide an illustrative overview of these conditions in order to make radiologists aware of them and avoid misdiagnosis for timely appropriate management. Teaching Points • Cystic adventitial disease diagnosis is based on evidence of cysts within artery walls. • A variety of anatomic variations may result in PAES. • PAES may be bilateral. • PAA is most commonly encountered in men. • Acute complications of PAA include acute thrombosis and distal embolization.

Abstract
OBJECTIVES This study was conducted to compare the early and mid-term results of the medial and posterior approaches in the surgical treatment of popliteal artery aneurysms (PAAs). METHODS From 1992 to 2006 in three hospitals, 110 popliteal aneurysms needed surgical repair by a posterior or a medial approach. Of 36 aneurysms repaired by the posterior approach, 33 could be case-matched to a medially excluded PAA according to the criteria of (1) patient age, (2) cardiovascular comorbidity, (3) indication for PAA repair, (4) diameter of PAA at time of surgical repair, (5) number of distal outflow vessels at time of surgical repair, and (6) type of bypass or interposition graft (venous or polytetrafluoroethylene). RESULTS During the 30-day postoperative period, seven complications (21%) occurred in each group, no patients died, and no amputations were necessary. Two patients in the posterior group vs none in the medial group (P < .05) needed thrombectomy because of occlusion of the reconstruction. The mean follow-up was 47 months (range, 2 to 176). In this period, 13 deaths occurred, but none were related to the previous interventions. The primary patency rates at 6 months and at 1, 3, and 4 years were 84%, 79%, 66%, and 66% in the posterior group and 96% (P < .05), 93% (P < .05), 76% (P = NS), and 69 % (P = NS) for the medial group, respectively. The secondary patency rates at 6 months, and at 1, 3, and 4 years were 100%, 100%, 100%, and 90% in the posterior group and 96%, 96%, 96%, and 90% in the medial group, respectively (P = NS). Limb salvage rates were 97% for the posterior group and 100% for the medial group (P = NS). No neurologic complications or venous damage was seen in either group. Irrespective of approach, venous reconstructions resulted in significantly higher patency rates compared with prosthetic reconstructions at the 3-year follow-up (84% vs 67%, P < .01). During follow-up, which included duplex scanning, two patients in the medial group needed renewed surgical intervention and posterior exclusion because of persistent flow and growth of the native aneurysm. CONCLUSION Early (<1 year) primary patency rates of the medial approach were significantly better than the posterior approach, possibly because of the limited posterior exposure. However, in the absence of a significant difference in long-term primary and secondary patency rates between the posterior and medial approach, and considering the substantial risk of aneurysm growth after medial approach (up to 22%), the posterior approach might be the surgical method of preference for PAA repair in the long run.

Abstract
OBJECTIVES The aim of this study was to assess the national management and outcome of popliteal artery aneurysm (PAA). METHODS In the Swedish National Registry 717 primary operations for PAA on 571 patients were registered prospectively between 1987 and 2002. 235 legs [corrected] presented with acute ischemia. RESULTS Median age was 70 for men and 75 for women. Immediate surgery was performed in 135 legs, including intraoperative thrombolysis in 32 cases (Immediate Surgery Group, ISG). Pre-operative thrombolysis was performed in 100 legs, followed by acute (<or=24 hours, 41 legs) or elective (59 legs) surgery (Delayed Surgery Group, DSG). DSG had smaller PAA (27 versus 37 mm, p<0.0001) and were younger (67 versus 72 years, p<0.001). Run-off was worse in DSG than in ISG (p<0.001) and improved in 87% after thrombolysis. Amputation-rate was 27% in the ISG and 7% in the DSG, P<0.0001. The ISG required fasciotomy in 30% compared to 11% of the DSG, p=0.0001. CONCLUSION Patients in the ISG and DSG differed in their pre-operative characteristics and were selected to the treatment modalities in a complex manner. Preoperative thrombolysis improves run-off.

Abstract
BACKGROUND Popliteal artery aneurysms (PAAs) are rare, but thromboembolic complications may result in limb loss. To define complications and outcomes after open surgical repairs, we reviewed our experience. METHODS Clinical data of patients with PAA seen between 1985 and 2004 at Mayo Clinic, Rochester, Minnesota, were reviewed and outcomes in 289 patients with open revascularization were analyzed. Kaplan-Meier method with log-rank tests, chi(2), and Wilcoxon rank sum tests were used for analysis. RESULTS A total of 358 PAAs were treated in 289 patients, consisting of 281 (97%) men and eight (3%) women. There were 133 (46%) unilateral and 156 (54%) bilateral PAAs with a mean diameter of 2.9 cm (range, 1.5 to 9 cm). Abdominal aortic aneurysm (AAA) was more frequent with bilateral than unilateral PAAs (65% [101/156] vs 42% [56/133] P = .001). There were 144 (40%) asymptomatic limbs (group 1), 140 (39%) had chronic symptoms (group 2), and 74 (21%) had acute ischemia (group 3). Great saphenous vein (GSV) was used in 242 limbs (68%), polytetrafluoroethylene (PTFE) in 94 (26%), and other types of graft in 22 (6%). Early mortality was 1% (3/358), all in group 3 (4% [3/74]). Six of seven patients with perioperative myocardial infarctions belonged to group 3 (8%). The 30-day graft thrombosis rate was 4%, with 1% in group 1 (1/144), 4% in group 2 (5/140), and 9% in group 3 (7/74). All six early amputations (8%) were in group 3, five with failed bypass (4 PTFE, 1 GSV). Mean follow-up was 4.2 years (range, 1 month to 20.7 years). The 5-year primary and secondary patency rates were 76% and 87%, respectively, higher with GSVs (85% and 94%) than PTFE (50% and 63%, P < .05). Seven recurrent PAAs (2%) required reintervention. The 5-year freedom from reintervention was 100% after endoaneurysmorrhaphy vs 97% after ligations (P = .03). Five-year limb salvage rate was 97% (85% in group 3). There was no limb loss in group 1 and none in group 2 with GSV. In group 3, preoperative thrombolysis reduced the amputation rate in class II patients with marginally threatened limbs (96% vs 69%, P = .02). CONCLUSION Acute presentation of PAA continues to carry high mortality and cardiac morbidity; although preoperative thrombolysis appears to improve results, the 8% early and 15% late amputation rates remain ominous. Early elective repair is recommended because these patients had no surgical mortality, a low rate of complications, and asymptomatic patients had no limb loss at 5 years. GSV and endoaneurysmorrhaphy continues to be the gold standard for open repair of PAA.

Abstract
Popliteal artery aneurysms account for 85% of all peripheral aneurysms and are frequently associated with abdominal aortic aneurysms. Up to 75% of all popliteal artery aneurysms are discovered in symptomatic patients who present with arterial insufficiency, leg swelling, or pain. Popliteal artery aneurysms can be diagnosed with duplex ultrasonography. Aneurysm repair should be considered for all symptomatic patients with rest pain or limb-threatening symptoms. Asymptomatic aneurysms larger than 2 cm should also be treated to prevent the development of limb-threatening ischemia and assure better surgical bypass graft patency and longer freedom from amputation. Conventional aneurysm repair consists of either opening the aneurysm sac and interposing a bypass graft or aneurysm ligation combined with bypass grafting. If the aneurysm sac is left intact, side branch perfusion may persist and the aneurysm may continue to enlarge and can rupture. Endovascular popliteal aneurysm repair has not demonstrated clinical equipoise to standard surgery but may be advantageous in select high-risk patients.

Abstract
BACKGROUND Popliteal artery aneurysms (PAA) are the most common peripheral aneurysm and are recognized as 'the silent killer of the leg circulation'. The timing and type of interventions used in their treatment is still controversial. This review examines the published data on the natural history, epidemiology, clinical presentation and management options available. The aim of this study is to try and reach a consensus with regards to the best management of PAA. METHOD A systematic review of data in the English published works since 1980. RESULTS The authors include 53 studies containing 2854 patients with 4291 PAA. Most published data involves retrospective studies and personal experience, with one multicentre study. No randomized controlled studies exist regarding the management of PAA. CONCLUSIONS 1. Although most PAA are of atherosclerotic origin in old patients, trauma, infection and family history are the main causes in young patients. 2. Great vigilance is needed for diagnosis as only approximately five patients are seen each year by a major vascular centre. There is no place for screening programmes to detect PAA. 3. Approximately 45% of patients are asymptomatic at the time of initial diagnosis. Aortic aneurysms are found in 40% and bilateral PAA in 50% of patients. More than 95% of patients are men with a mean age of 65 years and 45% have hypertension. 4. Surgical reconstruction is recommended for all symptomatic and asymptomatic aneurysms larger than 2 cm. Five-year graft patency rates after surgical repair range from 30 to 97%, with 5-year limb salvage ranging from 70 to 98%. Patient survival rates at 5 and 10 years are 75 and 46%, respectively. 5. If carried out carefully, intra-arterial thrombolysis can safely prepare patients presenting with acute ischaemia from occluded PAA, for surgical revascularization to restore distal run-off. 6. Endovascular repair of a PAA is a feasible option, although little evidence is yet available. 7. Lifelong, careful patient surveillance is essential to detect and treat new aneurysms at other sites.

Abstract
OBJECTIVE Popliteal artery aneurysm (PAA) is uncommon. The clinical presentation of PAA includes rupture, embolism, and thrombosis. In this article, we evaluate the results of our 20-year experience with surgical management of PAAs, analyzing the role of anatomic, clinical, and surgical factors that potentially affect early and long-term results. METHODS From January 1984 to December 2004, 159 PAAs in 137 patients were operated on at our department. Data from all the patients were retrospectively collected in a database. PAAs were asymptomatic in 67 cases (42%); 5 (3%) PAAs were ruptured. In 51 cases (32%), PAA caused intermittent claudication. The remaining 36 limbs (23%) had threatening ischemia due in 30 cases to acute PAA thrombosis, in 4 cases to chronic PAA thrombosis, and in 2 cases to distal embolization. In selected patients with acute ischemia, preoperative intra-arterial thrombolysis with urokinase was performed. Early results in terms of mortality, graft thrombosis, and limb salvage were assessed. Follow-up consisted of clinical and ultrasonographic examinations at 1, 6, and 12 months and yearly thereafter. Long-term survival, patency, and limb salvage rates were analyzed. RESULTS Forty cases were treated with aneurysmectomy and prosthetic graft interposition; in 39 cases, the aneurysm was opened, and a graft was placed inside the aneurysm. Four patients had aneurysmectomy with end-to-end anastomosis. In 73 cases, ligation of the aneurysm with bypass grafting (39 with a prosthetic graft and 34 with an autologous vein) was performed. The remaining three patients underwent endovascular exclusion of their PAAs. A medial approach was used in 97 patients (61%), and a posterior approach was used in 59 patients (37.1%). The outflow vessel was in most cases (93.7%) the below-knee popliteal artery. Thirty-day amputation and death rates were 4.4% (7/159 limbs) and 2.1% (3/137 patients), respectively. The amputation rate was significantly higher in symptomatic limbs than in asymptomatic ones (6.5% and 1.4%, respectively; P = .05). Eight limbs (5%) had an early graft thrombosis that required a reintervention. Follow-up was available in 116 patients (84.7%) and 138 limbs (86%) with a mean follow-up time of 40 months (range, 1-205 months). The cumulative estimated 60-month survival, limb salvage, and primary and secondary patency rates were 84.2%, 86.7%, 66.3%, and 83.6%, respectively. Asymptomatic limbs had significantly better results than symptomatic ones in terms of limb salvage (93.4% and 80.4%, respectively; P = .03; log-rank, 4.2) and primary patency (86.5% and 51.6%, respectively; P = .001; log-rank, 10.3). Among symptomatic patients, results were better in claudicant limbs than in acutely ischemic ones in terms of limb salvage (90.5% and 58.7%, respectively; P = .001; log-rank, 17.5). Univariate analysis showed the absence of symptoms, the presence of two or three tibial vessels, the use of a posterior approach, the kind of intervention, and the site of distal anastomosis to significantly affect long-term patency. Cox regression for factors affecting 60-month primary patency showed that clinical presentation, runoff status, and the site of distal anastomosis significantly influenced long-term results. CONCLUSIONS Results of surgery on asymptomatic PAAs are good-significantly better than those for symptomatic ones. Elective surgical intervention should be performed in patients with a low surgical risk and a long life expectancy when the correct indication exists. In thrombosed aneurysms, intra-arterial thrombolysis may represent an alternative to emergent surgical management. Our data demonstrated that results are similarly good in claudicants, and this fact confirms that only acute ischemia due to PAA thrombosis represents a real surgical challenge. In selected patients with focal lesions, a posterior approach seems to offer better long-term results. The runoff status and the site of distal anastomosis affect long-term patency as well.

Abstract
Popliteal artery aneurysms are the most common peripheral aneurysm. They are associated with concomitant contralateral popliteal aneurysms and abdominal aortic aneurysms. Patients with unrecognized aneurysms may present with acute limb ischemia and potential for limb loss. Use of preoperative lytic therapy to improve distal runoff prior to exclusion and bypass has significantly improved the outcome from acute thrombosis. Long-term follow-up has shown that both proximal and distal ligation of the aneurysm are important because a thrombosed aneurysm may begin to enlarge after a long period of quiescence. Popliteal aneurysms are now being treated with covered stents. This article delineates the current evaluation, preoperative planning, and surgical and endovascular approaches to this disease. With proper diagnosis and repair, excellent limb salvage and postoperative function has become the norm.

Abstract
OBJECTIVE The objective of this study was to determine the clinical value of vascular laboratory surveillance after open or endovascular repair of popliteal aneurysm by analysis of the frequency and nature of secondary interventions performed. METHODS Over an 8-year period, 55 popliteal artery aneurysms were repaired in 46 men (mean age, 72 years) by aneurysm ligation and bypass grafting (vein, 37; prosthetic, 7), endoaneurysmorrhaphy and interposition grafting (prosthetic, 3; vein, 1), or endograft exclusion (n = 7). Indications for intervention included aneurysm thrombosis with critical limb ischemia (n = 8), symptomatic (n = 10) or asymptomatic (n = 37), >1.75 cm popliteal aneurysm with mural thrombus. Catheter-directed thrombolysis was used in three limbs to restore aneurysm and tibial artery patency before open repair. Duplex ultrasound surveillance was performed after repair to identify residual and acquired lesions. Life-table analysis was used to estimate repair site intervention-free (primary) and assisted-primary patency. RESULTS During a mean 20-month follow-up interval, 20 secondary procedures were performed in 18 (31%) limbs to repair duplex-detected graft stenosis (n = 10), repair site thrombosis (n = 5), vein graft aneurysm (n = 3), graft entrapment (n = 1), or type 1 endoleak (n = 1). Primary patency was 76% and 68% at 1 and 3 years, and was uninfluenced by tibial artery runoff status or type of bypass conduit. Open (n = 12) or endovascular (n = 8) secondary procedures were performed on 15 (12 vein, 3 prosthetic) bypass grafts, 2 endografts, and 1 interposition graft. Mean time to repair graft stenosis (11 months) was shorter than to repair of vein graft aneurysm (37 months). Assisted-primary patency was 93% and 88% at 1 and 3 years; redo bypass grafting was required and successful in five limbs. Limb salvage was 100%. CONCLUSIONS One third of popliteal artery aneurysms repaired by open or endovascular procedures required a secondary intervention within 2 years of repair. Repair-site surveillance using duplex ultrasound was able to identify lesions that threaten patency, which resulted in excellent assisted patency and limb preservation rates when corrected.

Abstract
Thrombolytic therapy has been around for close to 30 years now,but its exact role in the treatment of acute and chronic arterial occlusive disease continues to be debated. Studies have produced varying and contradictory results. We are still not sure if thrombolysis has any true advantages over surgical thromboembolectomy,or which lytic agent is the best. Nonetheless, the technique still plays an important role in the treatment of arterial occlusions.

Abstract
The popliteal artery is a relatively short vascular segment but is affected by a unique set of pathologic conditions. These conditions, which may be common throughout the arterial system or exclusive to the popliteal artery, include atherosclerosis, popliteal artery aneurysm, arterial embolus, trauma, popliteal artery entrapment syndrome, and cystic adventitial disease. The clinical manifestations, imaging appearances, and treatment options associated with these pathologic conditions differ significantly. Consequently, the radiologist should be familiar with these conditions to direct imaging for accurate diagnosis and treatment and to prevent loss of limb.

Abstract
The objective of this study was to compare patency rates following the repair of popliteal aneurysms according to the site of inflow, material of bypass graft and quality of distal runoff. Seventy bypasses were performed over an 11-year period. Autogenous saphenous vein was used in 53 procedures (75.7%) and prosthetic material was used in 17 (24.3%). Early mortality was 2.8%. Early primary and secondary patency rates were 95.7% and 97.1%, respectively. Autogenous vein showed better 10-year patency than prosthetic material (86% vs. 57%; p = 0.02). No significant differences in patency were observed according to the inflow site (87.8% groin vs. 74.7% supragenicular). Bypasses that originated in the groin showed improved patency when a saphenous vein was used (84.8% vs. 43.7%; p = 0.01). However, no influence of the graft material was noted in supragenicular bypasses (90.4% vs. 84.8%; p = 0.6). Bypasses in extremities with good runoff showed better patency than those in limbs showing poor runoff (86% vs. 55%; p = 0.003). The use of saphenous vein for the repair of popliteal aneurysms showed better results than those with prosthetic material, although in bypasses originating from the distal superficial femoral or above-knee popliteal artery, no significant differences in patency were observed. Good distal runoff was associated with improved overall outcome.

Abstract
BACKGROUND Management of asymptomatic popliteal aneurysm is controversial, and the prognosis for acutely thrombosed aneurysm is notoriously poor. We evaluated the management and outcome for popliteal aneurysm. PATIENTS AND METHODS A retrospective review of all patients with popliteal aneurysm between 1988 and 2000 was carried out. Fifty-two limbs were operated on in 41 patients. Data collected included findings at presentation, operative details, graft patency, limb salvage, complications, and 30-day mortality. RESULTS Initial findings included acute ischemia (n = 14), no symptoms (n = 29), acute rupture (n = 2), chronic ischemia (n = 5), and symptoms of nerve or vein compressive (n = 2). All patients with symptomatic aneurysms and 22 patients with asymptomatic aneurysms (21 larger than 2 cm in diameter, 1 with thrombus at duplex ultrasound scanning) underwent surgery as first-line treatment. Of the 7 patients with asymptomatic aneurysm managed with surveillance with duplex ultrasound scanning, acute ischemia developed in three, 1 aneurysm ruptured, compressive symptoms developed in 1, and 2 remained asymptomatic but required surgery because of aneurysm enlargement (>2 cm). Of the 17 patients with acute ischemia, 13 had neurologic signs and underwent immediate thromboembolectomy (trifurcation alone in 8, ankle-level arteriotomy in 4) and bypass grafting (n = 12) or inlay grafting (n = 1), and the other 4 underwent intra-arterial thrombolysis initially. Of these 4 procedures, 2 were successful and had elective surgery; the other 2 required urgent surgery because of secondary distal embolism and failure of recanalization. Thirteen of the 17 grafts were to the crural vessels. Bypass grafting (medial approach) was used in 16 of the 17 patients with acute ischemia, all 5 patients with chronic ischemia, and the 8 patients with no symptoms. An inlay technique (posterior approach) was used in 16 patients with no symptoms, the 3 patients with symptoms of nerve or vein compression, and 1 patient with acute ischemia. The distal anastomoses were to the below-knee popliteal artery in 35 patients and the crural arteries in 15 patients, using autologous vein. Two of the patients with rupture underwent ligation alone, the other undergoing bypass grafting in addition. The overall 5-year primary patency rate was 69%, secondary patency rate was 87%, and limb salvage rate was 87%. Limb salvage was achieved in 14 of the 17 patients with acute ischemia. Patients with asymptomatic aneurysms had better secondary graft patency (100%) compared with symptomatic aneurysms (74%; P <.01). Acute ischemia, technique used, and crural artery grafts were not predictors of graft failure with either univariate or multivariate analysis. Symptomatic aneurysms were associated with more postoperative complications and greater 30-day mortality (4 of 28 vs 0 of 24). CONCLUSION Thromboembolectomy followed by crural bypass grafting is an effective treatment for popliteal aneurysm with severe acute limb ischemia. Outcome is better with surgical management of asymptomatic popliteal aneurysm compared with symptomatic aneurysm.
