Abstract
Background Iliac artery stenosis or occlusion is a critical condition that can severely impact a patient's quality of life. The effectiveness of balloon angioplasty and intraluminal stenting for the treatment of iliac artery lesions classified as TASC II A and B was evaluated in this single-center prospective study. Methods Conducted between October 2016 and September 2020 at Cho Ray Hospital's Vascular Surgery Department, this prospective study involved PAD patients categorized by TASC II A and B classifications who underwent endovascular intervention. Intervention outcomes were assessed peri-procedure and during short-term and mid-term follow-ups. Results Of the total of 133 patients, 34.6% underwent balloon angioplasty, while 65.4% received stenting. The immediate technical success rate was 97.7%, while the clinical success rate was 62.4%. Complications were minimal, with major limb amputation reported in 1.5% of the cases. There was a significant improvement in Rutherford classification and ABI at short-term follow-up, with a patency rate of 90.2%. The mid-term post-intervention follow-up yielded similar results with an 86.1% patency rate. The mortality rates associated with arterial occlusion were 2.3% during short-term follow-up and 1.7% during mid-term follow-up. Conclusion Balloon angioplasty and stent placement are effective and safe interventions for TASC II A and B iliac artery occlusions with favorable short and mid-term outcomes. Further, multi-center studies with larger sample sizes are recommended for more comprehensive conclusions, including long-term follow-up assessment.

Lee K, Cho S, Kim H, Joh JH. Incidence and Risk Factors of Iliac Artery Rupture during Aortoiliac Stenting. Vasc Specialist Int 2024; 40:5. [PMID: 38389133 PMCID: PMC10884543 DOI: 10.5758/vsi.230114] [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: 11/17/2023] [Revised: 01/23/2024] [Accepted: 02/05/2024] [Indexed: 02/24/2024] Open
Abstract
Purpose Aortoiliac occlusive disease (AIOD) is widely prevalent and leads to severe claudication or chronic limb-threatening ischemia. Stent placement for AIOD demonstrated excellent outcomes in terms of long-term patency. However, iliac artery rupture is the most fearful complication during the aortoiliac stenting (AIS). This study aimed to evaluate the incidence and risk factors of iliac artery rupture during AIS. Materials and Methods A retrospective review of consecutive patients with AIOD treated with AIS from 2009 to 2021 was completed. We excluded patients with instent restenosis. All types of stents, including self-expanding stent (SES), balloon-expandable stent (BES), or balloon-expandable covered stent (CS), were used. Angiographic characteristics and procedural outcomes were analyzed. Procedural success was defined as the residual stenosis <30%. Results A total of 242 patients (86.8% male; mean age 68.8±10.0 years) with de novo AIOD were treated with AIS. The procedural success rate was 100%. Rupture occurred in six patients (2.5%) and all ruptures were occurred in the external iliac artery (EIA). Stenting of the EIA and less calcified lesion were risk factors for iliac rupture (P=0.028). All cases of iliac artery rupture were successfully treated with the CSs. Overall primary patency rates were 98.0% and 93.4% at 12 and 36 months, respectively. Primary patency rates of SES, BES, and CS were 87.7%, 88.4%, and 100% at 36 months, respectively. Conclusion The incidence of iliac artery rupture during AIS was 2.5%. Stent placement in the less calcified lesion and EIA was a risk factor for rupture during AIS. Placement of the CS can be the straightforward solution in case of iliac artery rupture during AIS.

Outcomes of Hypogastric Coverage and Occlusion during Endovascular Treatment of Aortoiliac Occlusive Disease. Ann Vasc Surg 2021; 77:116-126. [PMID: 34411668 DOI: 10.1016/j.avsg.2021.05.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Revised: 04/01/2021] [Accepted: 05/06/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND The risk of hypogastric occlusion (HO) following bare-metal stent (BMS) coverage of the hypogastric origin during endovascular treatment of aortoiliac occlusive disease (AIOD) is unclear. This study sought to determine the rate and clinical significance of HO following BMS coverage during iliac stenting for complex AIOD. METHODS Consecutive patients undergoing elective iliac stenting for AIOD from 2010-2018 at Cleveland Clinic were reviewed. Patients with BMS coverage of a patent hypogastric origin were included. Rate of HO were determined by review of intraoperative angiography and follow up imaging. Predictors of HO were identified by univariable and multivariable logistic regression. Outcomes were compared between those who did and did not develop HO. RESULTS There were 251 patients (338 limbs) with BMS coverage of the hypogastric origin during treatment of AIOD. Lesion severity was classified as TASC C/D in 249/338 (73.7%) of cases. Bilateral hypogastric coverage occurred in 93/251 (37.1%) patients. Hypogastric patency was 78.1% at 24-months following coverage. Recanalization of an ipsilateral external iliac artery (EIA) occlusion was predictive of HO (HR 3.12, 95% CI: 1.33, 7.34; P= 0.009). Increased luminal diameter of the hypogastric origin protected against HO (HR 0.64; 95% CI: 0.47, 0.88; P= 0.006). Perioperative outcomes were no different between patients with and without HO. There were no cases of gluteal necrosis, spinal cord ischemia, or pelvic organ ischemia. Four-year mortality and limb salvage were not affected by HO. HO was associated with decreased primary patency of ipsilateral iliac stents and increased risk of ipsilateral reintervention (HR 5.49; 95% CI: 1.82, 16.58; P= 0.002). CONCLUSIONS HO is relatively infrequent following BMS coverage during treatment of AIOD. Luminal diameter of the hypogastric origin and ipsilateral EIA occlusion are associated with occlusion. HO is well tolerated in AIOD, though it is potentially associated with increased risk iliac stent occlusion and reintervention.

Abstract
Retroperitoneal hemorrhage from iliac artery injury is a potentially serious complication of vascular interventional procedures leading to hemorrhagic shock and death if not diagnosed early and treated promptly. We report a 70-year-old male admitted to our facility with non-ST-elevation myocardial infarction, whose heart catheterization revealed left anterior descending artery (LAD) with 80% proximal, 95% mid and 100% distal disease. The left circumflex and right coronary arteries were 100% occluded proximally and received collaterals from the LAD. The patient declined coronary artery bypass surgery; therefore, the decision was made to perform high-risk percutaneous coronary intervention (PCI) of the LAD with Impella left ventricular assist device support. Left femoral artery angiogram revealed severely tortuous and calcified aorta, left external iliac and left common iliac arteries, and was accessed with 14-inch Impella sheath. He developed groin pain with mild hypotension thought to be due to sedation, which responded to intravenous fluids and dopamine. He underwent successful rotational atherectomy of the proximal and mid LAD with deployment of drug-eluting stents. Following PCI, he suffered acute profound hypotension necessitating intravenous fluids and vasopressor support with epinephrine. Emergency transthoracic echocardiogram did not reveal any pericardial effusion, and showed normal left ventricle and right ventricle systolic function. The Impella device was removed and selective left common iliac angiogram from the right femoral access revealed a vascular injury site with shift of the bladder to the right indicative of retroperitoneal hematoma. A digital subtraction angiogram revealed extravasation of blood at the vascular injury site. An 8.0 × 59 mm iCAST covered stent was deployed to the left external iliac artery with successful sealing of the perforation. The Impella device site was closed with two Perclose devices. The patient required 4 units of packed red blood cell transfusion. His hospital course was complicated by transient acute kidney injury, with return of his renal function to baseline at discharge 10 days later. This case underscores the importance of prompt recognition and treatment of vascular complications associated with interventional procedures, and highlights some of the risk predictors of such complications, which should be anticipated and planned for prior to intervention.

Abstract
Purpose: To evaluate the safety and effectiveness of primary stenting of the common (CIA) or external iliac artery (EIA) using the Visi-Pro Balloon-Expandable Peripheral Stent System for treatment of stenotic, restenotic, or occluded lesions. Methods: Between 2011 and 2012, 75 patients (mean age 64.2±8.9 years; 46 men) with Rutherford category 2–4 ischemia and atherosclerotic lesions ≤10 cm in length underwent iliac artery stenting at 17 centers in the United States and Europe. The primary outcome of the study was the major adverse event (MAE) rate at 9 months postprocedure [composite of periprocedural death, in-hospital myocardial infarction, clinically driven target lesion revascularization (CD-TLR), and amputation of the treated limb]. Secondary outcomes included 30-day MAE rate, 9-month primary patency, changes in ankle-brachial index (ABI) and the Walking Impairment Questionnaire at 30 days and 9 months postprocedure, device success, and clinically driven target vessel revascularization (CD-TVR) at 30 days and 9 months. Outcomes in specific patient cohorts (ie, gender, stent location, calcification severity, and lesion grade) were analyzed. Results: Eighty-one stents were implanted in 61 CIA and 15 EIA lesions (41 with moderate/severe calcification). The mean lesion treated length was 29.3±13.9 mm. All devices were successfully deployed. MAE occurred in 3 (4.0%) of 75 subjects at 9 months. Primary patency and freedom from CD-TVR at 9 months were both 95.8%. ABI improved from 0.67±0.14 at baseline to 0.94±0.14 and 0.96±0.16 at 30 days and 9-month follow-up, respectively (p<0.001 for both). There were no differences with respect to any of the analyzed patient characteristics, including gender. Conclusion: Nine-month results of the VISIBILITY Iliac stent study (ClinicalTrials.gov identifier NCT01402700) demonstrated safety and effectiveness for the treatment of atherosclerotic CIA and EIA lesions with the Visi-Pro stent across all treated cohorts.

Abstract
Exercise rehabilitation is a proven, yet poorly available, treatment for intermittent claudication, the primary symptom of peripheral arterial disease (PAD). Exercise rehabilitation is effective, non-invasive, and associated with minimal cardiovascular risk in appropriate patients. Percutaneous transluminal angioplasty (PTA), especially of the iliac segment, is an alternative effective treatment for claudication. There are, however, minimal data currently available to compare the cost-effectiveness of these two interventions. We compared the cost-effectiveness of 3- and 6-month exercise programs with that of iliac PTA without stenting, using the incremental cost-effectiveness ratio [ICER 1/4 (Cost2 Cost1)=(Effectiveness2 Effectiveness1)]. The ICER represented the price of an additional meter walked derived from each treatment based on conservative models of success of each procedure and specific care assumptions. PTA and exercise efficacy data were derived from a literature review and exercise costs were modeled per the current CPT code 93668. Effectiveness was defined as absolute claudication distance (ACD) at 3 and 6 months. Three treatment alternatives were assessed: (1) no treatment, (2) PTA, and (3) exercise rehabilitation. At 3 months, PTA was more effective than exercise therapy and resulted in an additional 38 meters at an additional cost of $6719, for an ICER of $177=meter. At 6 months, however, exercise was more effective than PTA, resulting in an additional 137 meters walked, and costs less ($61 less per meter gained). In conclusion, exercise rehabilitation at 6 months is more effective and costs less than PTA, and is therefore cost-saving. The cost-effectiveness and availability of claudication treatments has national implications for future PAD care; however, data to inform these care choices can best be obtained in prospective clinical trials.

Abstract
Lower extremity wounds resulting from ischemia are increasingly becoming a common indication for surgical revascularization. Techniques in minimally invasive vascular surgery for the treatment of lower extremity chronic ischemia have expanded rapidly in recent years. The current standard of care with which all new modalities should be compared is the restoration of arterial flow via direct arterial revascularization using the autogenous reversed saphenous vein that can yield limb salvage rates of approximately 95%. Percutaneous transluminal angioplasty and stenting (PTA/S), cryoplasty, catheter-directed atherectomy, laser-assisted PTA/S, drug-eluting stents, and subintimal angioplasty are emerging minimally invasive modalities used for the treatment of lower extremity ischemia. Early success rates using many of these techniques have been promising. The outcomes of randomized controlled trials with long-term follow-ups are needed to make confident remarks about the effectiveness of these techniques.

Abstract
Purpose: Penetrating subclavian arterial injuries are often difficult to treat. Standard surgical techniques require wide exposure and dissection in traumatized areas, which is often challenging. This report summarizes the early results of endovascularly placed stented grafts for the treatment of penetrating subclavian arterial trauma. Methods: Six patients with penetrating injuries of the subclavian artery had stented grafts inserted to repair five pseudoaneurysms and one arteriovenous fistula. The stented grafts consisted of a polytetrafluoroethylene graft sutured over a balloon-expandable Palmaz stent. The devices were inserted from an ipsilateral brachial arteriotomy and deployed using fluoroscopic guidance in the operating room. Results: Immediate success was obtained in all procedures (100%). All patients continue to have patent grafts with a follow-up ranging from 7 to 30 months (mean 19 months). The only procedure-related complication was the need for a brachial artery patch angioplasty at the site of device insertion in the first patient. There was one other patient who developed a stent fracture at 8 months; a second stent was inserted. Duplex studies up to 24 months later show no recurrence in this patient. Conclusions: Endovascular stented grafts offer an effective, less invasive alternative to standard techniques in treating traumatic arterial lesions. Early results are encouraging, but long-term follow-up will be necessary to fully delineate the effectiveness of this technique.

Abstract
Purpose: The standard endpoint for lower limb revascularization is long-term patency; however, in high-risk patients with end-stage ischemia, healing of chronic ulcerations has been proposed as an acceptable endpoint. To evaluate if today's minimally invasive interventions, in combination with comprehensive wound healing procedures, can resolve nonhealing wounds, we performed a retrospective review of chronic ulceration patients treated at the San Francisco Wound Care Center. Methods: Eight-five patients with 96 limbs at risk due to nonhealing ulcers were treated with a variety of endovacular procedures: 7 patients (group 1) received PalmazR stents for unilateral iliac occlusions; 42 limbs (group II) in 39 patients were treated with balloon angioplasty for superficial femoral and popliteal lesions; and 47 extremities in 39 patients (group III) underwent rotational atherectomy for tibioperoneal lesions. Comprehensive wound management techniques, including the application of growth factors, were used. Results: All group I wounds healed, although 6 of 7 patients required additional procedures to address outflow lesions. In groups II and III, primary patencies were similar (64% and 70%, respectively), and nine treated sites reoccluded in each group. Restenotic lesions were retreated in both groups (three in group II and four in group III); secondary patencies were 71% and 78%, respectively. There were more amputations in group III patients (five) compared to group II (one). In both groups after 5 months, 90% of wounds had healed in group II and 72% in group III. Conclusion: The use of endovascular procedures appears to play an important role in the healing of chronic lower extremity ulcerations in high-risk patients with end-stage ischemia.

Abstract
Purpose: Endovascular exclusion of arterial injuries associated with arteriovenous fistulas and pseudoaneurysms has only recently been described using various stent-graft prostheses. This report details a transbrachial technique used to exclude an axillary artery pseudoaneurysm developing at the axillary anastomosis of an axillofemoral graft. Methods and Results: Thin-walled polytetrafluoroethylene was expanded with an angioplasty balloon catheter and used to cover standard Palmaz stents. Two covered stents were delivered under fluoroscopic guidance via open brachial artery access to the site, resulting in complete exclusion of the pseudoaneurysm. Follow-up duplex scanning confirmed aneurysm exclusion 3 months postprocedure. Conclusions: This technique can be applied in arteries of different sizes and lengths, using currently available materials. However, the long-term behavior of these devices in the arterial tree must be determined before their widespread use can be recommended for most indications.

Abstract
Purpose: To retrospectively evaluate the performance of a new self-expanding nitinol stent in the treatment of lower limb arterial occlusive lesions. Methods: The Sinus stent is a flexible, laser-cut device with good radiopacity and radial strength, allowing precise placement via a 7-F introducer, even in tortuous arteries. Over a 3.5-year period, 315 patients (254 men; mean age 64.9±10.8 years, range 39–93) had 403 lower limb lesions treated: 172 iliac (132 stenoses, 40 occlusions), 204 femoral (131 stenoses, 73 occlusions), and 27 popliteal (19 stenoses, 8 occlusions). The majority of patients (272, 86%) were in stage IIb of Fontaine's classification, 31 (10%) in stage III, and 12 (4%) in stage IV. Mean lesion lengths were iliac: 51.9±32.1 mm, femoral: 66.3±51.5 mm, and popliteal: 44.3±27.2 mm. Indications for stenting were 222 postdilation residual stenoses, 125 dissections, and 35 restenoses; 21 lesions were directly stented. Results: Immediate technical success was 100%. Clinical success was 98%. The anklebrachial index increased from 0.62±0.12 to 0.91 ±0.14. In 64 lesions, there were 3 early thromboses. Mean follow-up was 16.1 ±9.7 months (range to 40). There were 79 restenotic episodes: 14 iliac, 56 femoral, and 9 popliteal. Primary and secondary patencies for all lesions at 3 years were 72.5%±6.6% and 81.8%±5.9%, respectively. Stenoses demonstrated better patency than occlusions (primary: 78.0%±7.3% versus 60.2%±7.1%, p<0.001; secondary: 86.8%±6.1% versus 71.3%±6.7%, p<0.001). Men had better secondary patency at 3 years (83.7% versus 73.4%, p<0.05). For femoral lesions >8 cm, the results were acceptable for stenoses (66.7% primary and secondary patency at 3 years), but for lengthy occlusions, the restenosis rate was high (50.0% for occlusions versus 25.0% for stenoses, p<0.05). Conclusions: Angioplasty with the Sinus stent seems safe and effective in the treatment of peripheral arterial occlusive diseases, giving excellent results at the iliac and common femoral artery levels. Treatment results are better for stenoses than for occlusions. An occlusion length ≤8 cm seems to be the limit for stenting.

Abstract
For more than 10 years, endoluminal therapy has been marked by an explosion in the number and variety of devices designed to enhance or supplant its first and still most commonly used technique, balloon angioplasty. Among all these innovative catheter-based technologies, only stents have emerged as a truly effective device capable of achieving results comparable or superior to balloon angioplasty. In combination with thrombolysis and balloon dilation, they form the triadic foundation of endovascular surgery today. The prudent and judicious use of these tools, and a few other “niche” devices, such as atherectomy, in conjunction with classical vascular surgical techniques is the special and unique purview of the vascular surgeon. His development of a therapeutic plan, whose components include patient selection, lesion assessment, device decisions, procedure monitoring, completion evaluation, and follow-up, is incumbent upon an appreciation of the capabilities of each available intraluminal device in the various arterial segments and lesion pathologies. The strategies that facilitate optimum matching of endoluminal tools and techniques to each patient situation form the basis of this report. They offer today's vascular surgeon a guide to the use of intraluminal therapies in daily practice. On the horizon is the new and exciting technique of endoluminal grafting, which, if it proves efficacious, will bring about profound changes in our specialty.

Abstract
Purpose: Femoral stenting has demonstrated inconsistent and often disappointing long-term results. To compare our experience, we retrospectively analyzed a series of patients who had Palmaz balloon-expandable stents placed exclusively for superficial femoral artery (SFA) lesions. Methods: From January 1990 to November 1993, 39 patients were evaluated for claudication (79%) or critical ischemia in 42 limbs. The culprit lesions were confined to the SFA: 24 (57%) occlusions and 18 (43%) stenoses, including 3 restenotic lesions. Stenting was elective in 12 (29%) cases: the 3 restenoses and 9 chronic, calcified occlusions. The remaining stents were applied for postangioplasty residual stenosis or angioscopic findings of thrombogenic luminal irregularities. A total of 55 prostheses were successfully implanted. All patients were maintained on ticlopidine and followed by routine duplex scanning. Follow-up angiography was performed in 28 (72%) patients between 4 and 45 months. Results: In the postprocedural period, two acute thromboses (4.8%) occurred within 48 hours in patients who had long occlusions and poor runoff; no other major complications were encountered, for a clinical success rate of 95%. Follow-up evaluation ranged from 4 months to 4 years with a mean of 25 months. The restenosis rate was 19% (34% in occlusions; 10% in stenotic lesions, p = NS). At 24 months, cumulative primary patency was 77% and secondary patency 89%. Conclusions: Palmaz stents performed well in the SFA, demonstrating a low acute thrombosis rate and good long-term patency. The incidence of restenosis is likely to be greater in occlusions than in stenoses.

Abstract
Management of iliac artery disease has evolved over the years, from a surgical-only approach to a primarily endovascular-only approach as the first line treatment option. This has been continuously improved upon with the advent of new devices and applied technologies. Most recently in particular, the literature has shown good, reliable outcomes with the use of self-expandable stents in iliac artery atherosclerotic lesions. Nevertheless, no device is without its limitations, and the Absolute Pro® Vascular Self-Expanding Stent System was designed with the intent of overcoming some of the shortcomings of other available stents while maintaining acceptable postprocedural outcomes. Based on preliminary industry-acquired data, it has achieved these goals and appears to be an emergent competitor for the treatment of both focal and complex iliac artery lesions.

Abstract
PURPOSE To determine the clinical and technical outcomes following endovascular therapy for aortoiliac occlusive disease, including complex reconstruction of the aortic bifurcation. METHODS A retrospective database search identified 1184 consecutive patients (864 men; mean age 64±10 years) who underwent 1712 procedures to treat target lesions in the distal aorta and iliac arteries from September 1996 to December 2006. The intended strategy was to open only one femoral access site primarily, so a second puncture was needed only for the kissing balloon technique at the aortic bifurcation. The primary endpoint was a 1-year duplex-based primary patency; secondary endpoints included acute technical success (residual stenosis <30%), secondary patency, and target lesion revascularization (TLR). Results were stratified by lesion morphology, which was classified according to the TransAtlantic Inter-Society Consensus (TASC II) document. RESULTS Most of the interventions were done in the iliac arteries (n=1337); 292 cases involved the aortic bifurcation, and 83 cases were in the distal aorta/aortic bifurcation. The mean follow-up was 3.24 years (range 0-12.7). In the entire study cohort, the 12- and 24-month restenosis, TLR, and primary/secondary patency rates did not differ among TASC II A-D subgroups. The symptom-driven TLR in the entire cohort was 8% and 9% at the 12- and 24-month follow-up, leading to secondary patency rates of 96% and 91% in the entire cohort. Outcomes for complex interventions in the distal aorta or aortic bifurcation did not differ significantly compared to the total cohort. The overall survival without restenosis, amputation, or surgery in TASC II subgroups A+B was higher (69.6%±1.5%) compared to TASC II C+D lesions (62.8%±1.9%, p=0.001). CONCLUSION The indication for percutaneous intervention in aortoiliac occlusive disease can be extended to complex TASC C and D lesions in experienced endovascular centers, even if complex reconstruction of the distal aorta or the aortic bifurcation is indicated.

Abstract
OBJECTIVES We sought to evaluate the procedural characteristics and clinical outcomes of endovascular repair for iliac artery (IA) in-stent restenosis (ISR). BACKGROUND An increasing percentage of patients with complex IA occlusive disease are treated with an endovascular approach, but the outcomes of IA-ISR have not been well described. METHODS We analyzed all endovascular procedures for treatment of IA-ISR performed at our institution between July 2006-December 2010. The primary outcome was primary patency, defined as <50% stenosis as assessed by clinical examination and duplex ultrasonography (DUS). RESULTS Forty-one lesions in 24 patients who underwent repeated endovascular intervention for treatment of IA-ISR. Most lesions were unilateral and involved the common IA (66%). The mean length of ISR was 30.1 ± 14.1 mm with type I (focal) and II (diffuse) ISR occurring with the greatest frequency (34% and 39%, respectively). All patients underwent balloon angioplasty; adjunctive stenting zwas performed in 27 (66%) of the lesions. Type II ISR lesions more frequently required stenting (13/16 lesions, P = 0.02 compared with other patterns of ISR). Procedural success was 100% with a mean gain of 0.13 in the ankle-brachial index (P = 0.001). The 6- and 12-month primary patency rates were 96% and 82%, respectively. The 12-month primary-assisted patency rate was 90% with clinically driven target lesion revascularization (TLR) in three patients. CONCLUSIONS Endovascular treatment of IA-ISR using an approach of balloon angioplasty followed by selective stenting is associated with high-patency rates and low rates of TLR at 1 year.

Abstract
The treatment options for infra-renal arteriosclerotic occlusive (ASO) vascular disease have never been more varied. The history of open revascularization procedures now exceeds 60 years. This represents three generations of vascular surgeons, the most recent of whom have witnessed more than 30 years of endovascular surgery development and dissemination. Both open and endovascular treatments should be considered mature; moreover, we are improving our understanding of the strategies and tactics that lead to the clinical application of one approach instead of the other. There are other important factors in the choice of a treatment modality to be used for a specific patient. Prime among these is evolving patterns of occlusive disease and the increasing severity of arterial calcification.

Abstract
The management of aortoiliac insufficiency has been improved considerably since the introduction of balloon-expandable stents in 1991. Although numerous studies have shown the safety and efficacy of balloon-expandable iliac artery stent placement, the procedure is not without potential complication. We report here a very unusual case of iliac artery stenting being complicated by deformation and elongation of the stent following balloon rupture at initial deployment with retention of the distal balloon marker and our successful approach to subsequent management with combined acetylsalicylic acid and clopidogrel. In conclusion, this conservative approach may be an alternative treatment of a partially deployed aortoiliac stent with a retained foreign body when further intervention is considered to be of high risk.

Abstract
OBJECTIVE This trial was conducted to determine if covered stents offer a patency advantage over bare-metal stents in the treatment of aortoiliac arterial occlusive disease. METHODS The Covered Versus Balloon Expandable Stent Trial (COBEST), a prospective, multicenter, randomized controlled trial, was performed involving 168 iliac arteries in 125 patients with severe aortoiliac occlusive disease who were randomly assigned to receive a covered balloon-expandable stent or bare-metal stent. Patient demographic data, clinical signs and symptoms, TransAtlantic Inter-Society Consensus (TASC) classification, and preprocedure and postprocedure ankle-brachial index measurements were recorded. The primary end points included freedom from binary restenosis and stent occlusion of the treated area, as determined by ultrasound imaging or quantitative visual angiography, or both. Postprocedural follow-up was at 1, 6, 12, and 18 months. RESULTS Aortoiliac lesions treated with a covered stent were significantly more likely to remain free from binary restenosis than those that were treated with a bare-metal stent (hazard ratio [HR], 0.35; 95% confidence interval (CI), 0.15-0.82; P = .02). Freedom from occlusion was also higher in lesions treated with covered stents than in those treated with a bare-metal stent (HR, 0.28; 95% CI, 0.07-1.09); however, this did not reach statistical significance (P = .07). Subgroup analyses demonstrated a significant difference in freedom from binary restenosis for covered stents in TASC C and D lesions compared with a bare stent (HR, 0.136; 95% CI, 0.042-0.442). This difference was not demonstrated for TASC B lesions (HR, 0.748; 95% CI, 0.235-2.386). CONCLUSIONS COBEST demonstrates covered and bare-metal stents produce similar and acceptable results for TASC B lesions. However, covered stents perform better for TASC C and D lesions than bare stents in longer-term patency and clinical outcome.

Abstract
INTRODUCTION Femoro-femoral crossover bypass is an extraanatomic reconstruction used for revascularization of lower limb with contralatateral femoral artery as an inflow vessel, and the graft placed in the suprapubic region. We perform this procedure when anatomic reconstruction is not possible or is contraindicated. OBJECTIVE To analyze the influence of different risk factors on early patency of femoro-femoral crossover bypass. METHODS This retrospective study analyzed the results of 88 femoro-femoral bypass grafting during an 11-year period. There were 66 (75%) males and 22 (25%) females of average age 64.93 years (42-79 years). In 76 patients the operations were performed due to critical limb ischemia. Revascularization was urgent in 12 patients, while 76 patients were elective. Dacron prosthesis was used in 81 patients, while PTFE was used in 7 patients. Statistical analysis was made by logistic regression. RESULTS During hospitalisation the graft remained patent in 82 patients, and graft thrombosis occurred in 6 patients. Limb salvage rate was 90.91%. Early morbidity rate (within the first postoperative month) was 13.64%, while early mortality rate was 4.55%. Using logistic regression we established that early graft patency was statistically more significant in males (p < 0.05). Age (p = 0.07) and hypertension (p = 0.08) appeared to be predicting influence of the graft patency on the border of the accepted statistical significance level. CONCLUSION Femoro-femoral crossover bypass is a good alternative for revascularization in high risk patients for standard anatomic reconstructions due to comorbid conditions or local problems.

Abstract
BACKGROUND Endovascular stents have been suggested as a means to improve the patency of arteries after angioplasty in patients with intermittent claudication. This is an update of a Cochrane review published in 2002. OBJECTIVES The null hypothesis to be tested by this review is that for individuals with claudication the use of an endovascular stent, in addition to percutaneous transluminal angioplasty, does not improve symptoms of life-style limiting claudication when compared to percutaneous angioplasty alone. SEARCH STRATEGY For this update the Cochrane Peripheral Vascular Diseases Group searched their Specialised Register (last searched August 2009) and the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (last searched 2009, Issue 3). SELECTION CRITERIA Randomised trials comparing angioplasty alone versus angioplasty with endovascular stents in patients with intermittent claudication. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted the data. Only published trial data were used but unpublished data were sought for the update. Effectiveness was measured by the pre-defined primary outcome measures restenosis or reocclusion rates and maximum walking distance. MAIN RESULTS Two studies were included involving a total of 104 participants. Both studies included only individuals with femoro-popliteal disease. They compared angioplasty and stenting with the Palmaz stent against angioplasty alone. Although one study showed a slight statistical advantage in arterial patency after angioplasty alone, this was not found when the two studies were combined. No differences in the secondary outcomes were detected in either study. AUTHORS' CONCLUSIONS The small number of relevant studies identified together with the small sample sizes and methodological weaknesses severely limit the usefulness of this review in guiding practice. The results from larger multicentre trials are needed.

Abstract
Peripheral arterial disease (PAD) affects about 27 million people in North America and Europe, accounting for up to 413,000 hospitalizations per year with 88,000 hospitalizations involving the lower extremities and 28,000 involving embolectomy or thrombectomy of lower limb arteries. Many patients are asymptomatic and, among symptomatic patients, atypical symptoms are more common than classic claudication. Peripheral arterial disease also correlates strongly with risk of major cardiovascular events, and patients with PAD have a high prevalence of coexistent coronary and cerebrovascular disease. Because the prevalence of PAD increases progressively with age, PAD is a growing clinical problem due to the increasingly aged population in the United States and other developed countries. Until recently, vascular surgical procedures were the only alternative to medical therapy in such patients. Today, endovascular practice, percutaneous transluminal angioplasty with or without stenting, is used far more frequently for all types of lower extremity occlusive lesions, reflecting the continuing advances in imaging techniques, angioplasty equipment, and endovascular expertise. The role of endovascular intervention in the treatment of limb-threatening ischemia is also expanding, and its promise of limb salvage and symptom relief with reduced morbidity and mortality makes percutaneous transluminal angioplasty/stenting an attractive alternative to surgery and, as most endovascular interventions are performed on an outpatient basis, hospital costs are cut considerably. In this monograph we discuss current endovascular intervention for treatment of occlusive PAD, aneurysmal arterial disease, and venous occlusive disease.

Abstract
BACKGROUND The success of a biomaterial implant may be affected by the surface chemistry's impact on protein adsorption. We have developed a series of poly(ethylene glycol) (PEG) containing, tyrosine-derived polycarbonates, which have been rendered radio-opaque by the iodination of tyrosine units in the copolymer backbone for use in resorbable biomedical implants including vascular stents and grafts. We tested the hypothesis that protein adsorption along with seeding, growth, and migration of human aortic smooth muscle cells (SMC) and human aortic endothelial cells (EC) will be modified by the presence of iodine and PEG within the polymer composition. METHODS Thin films of these polymers were prepared for the protein-material and cell-material interaction studies. Dot blot, SDS-PAGE, and XPS were used to evaluate relative protein adsorption. Cell adhesion and growth studies were performed using an MTS assay. Cell migration was evaluated using an injury model. RESULTS The presence of PEG attenuated protein adsorption, cell adhesion, and growth. With the subsequent incorporation of iodine, protein adsorption markedly increased while the antiadhesive effect of PEG was counteracted by iodine for EC and SMC adhesion and SMC growth. CONCLUSION Iodine incorporation into the polymer resulted in increased protein adsorption thus counteracting the effect of PEG.

METHODS Based on a prospectively maintained database, a retrospective analysis was conducted of 375 symptomatic patients (335 men; mean age 63+/-8 years) who underwent 438 interventions for aortoiliac arterial obstructions. Lesions were stratified according to the TASC II classification: 259 (59%) procedures involved TASC A/B lesions, while 113 (26%) were for TASC C and 66 (15%) for TASC D lesions. RESULTS The baseline characteristics of patients with TASC A/B lesions differed significantly in the ankle-brachial index (ABI), occurrence of renal insufficiency, and lesion characteristics from those with TASC C or D lesions. Acute treatment success, defined as residual stenosis <30%, was 100%, 96%, 93%, and 100% for TASC A, B, C, and D lesions, respectively. The primary 1-year patency rate, which was 86% for the entire study cohort, was similar for all TASC classifications (89%, 86%, 86%, 85% for TASC A to D lesions, respectively). In the TASC A/B cohort, the 5-year event-free survival (70%) was not significantly better than in the C/D cohort (57%, p=0.124). The clinical outcome, as measured by Rutherford stage and ABI, improved significantly in all TASC subgroups after successful intervention and was maintained up to 1 year. Stenting was an independent predictor for lower restenosis rates (HR 0.517, 95% CI 0.317 to 0.842; p=0.008). CONCLUSION In experienced hands, endovascular therapy of aortoiliac lesions can be successfully performed with sustained long-term outcome independent of the TASC II classification, even in class D lesions.

Abstract
We evaluated the long-term results of recanalization with primary stenting for patients with long and complex iliac artery occlusions. This was a retrospective nonrandomised study. Between 1995 and 1999, 138 patients underwent recanalization of an occluded iliac artery with subsequent stenting. Patency results were calculated using Kaplan-Meier analysis. The mean length of follow-up was 108 months. Variables affecting primary stent patency such as patient age; stent type and diameter; lesion site, shape, and length; Society of Cardiovascular and Interventional Radiology classification; total runoff score; Fontaine classification; and cardiovascular risk factors were analysed using Breslow test. These variables were then evaluated for their relation to stent patency using Cox proportional hazards test. Technical success was 99%. Primary patency rates were 90% (SE .024), 85% (SE .029), 80% (SE .034), and 68% (SE .052) at 3, 5, 7, and 10 years, respectively. Lesion site (p = 0.022) and stent diameter (p = 0.028) were shown to have a statistically significant influence on primary stent patency. Long-term results of iliac recanalization and stent placement were excellent, without major complications, even in highly complex vascular obstructions. A primary endovascular approach appears to be justified in the majority of patients as a less invasive alternative treatment to surgery. In any case, a first-line interventional approach should be considered in elderly patients or in patients with severe comorbidities.

Abstract
Endovascular therapy is the treatment of choice for type A and the preferred treatment for type B lesions. In selective patients, this type of treatment can be applied in type C and even type D lesions. Ipsilateral femoral, contralateral femoral, and brachial approach and both the intraluminal and subintimal space can be used for successful recanalization. The application of stents has improved the immediate hemodynamic and probably long-term clinical results of iliac percutaneous transluminal angioplasty. However, the superiority of primary or direct stenting over selective stenting has not been proven yet. The choice of stent type depends on lesion morphology and location but otherwise there is insufficient evidence to support the use of a particular stent design. There is insufficient evidence to justify routine use of covered stents. All patients should receive antiaggregant therapy following endovascular recanalization of iliac arteries. There is no consensus regarding prophylaxis with antibiotics in iliac recanalization procedures.

Abstract
The purpose of this study was to evaluate the long-term results of iliac artery stent placement with use of the symphony stent for the treatment of patients with intermittent claudication. In a prospective study, 31 cases of iliac occlusive arterial disease were treated in 26 patients. Stenoses (n = 27) were treated after failed angioplasty, and occlusions (n = 4) were treated with primary stent placement. Clinical history, clinical stage and the ankle brachial-index (ABI) examination measurement were assessed. The patients were followed up with clinical examination, ABI examination measurement and intravenous angiography. The follow-up period ranged between 9.5 months and 7.5 years (median = 5.9 yr). Data were analyzed using the univariate analysis (Kaplan-Meier method). The mean+/-SD ABI pre-, post-procedure and in the last control was 0.70+/-0.17, 0.97+/-0.15, and 0.96+/-0.20, respectively. Primary patency rates (%) +/- SE were 83+/-7 after 3 years, 75+/-8 after five years, and 67+/-9 after seven years, and secondary patency rates were 93+/-5 after three years, 86+/-7 after five years, and 86+/-7 after seven years. During the first 24 hours, one patient presented occlusion of the treated segment. During follow-up, 9 (29%) patients were admitted to our hospital because of worsening of the symptoms. In this study, the symphony stent has been proven to be a good device to treat lesions in the iliac region but more experience is needed to optimize endovascular treatment in this area. In our experience the treatment of iliac artery occlusive disease with symphony stents can be considered a good option with acceptable patency rates and low morbidity and mortality.

Abstract
Vessel rupture and perforation are important complications of percutaneous treatment of coronary and peripheral arterial disease. These complications can result in abrupt vessel closure, distal organ injury, bleeding into the surrounding tissue, and death. Prompt management of such complications is therefore critically important. This paper reviews the management of vessel rupture and perforation, including the use of different types of covered stents (balloon-expandable and self-expanding), as well as the various types of embolization coils. Particular focus will be placed on percutaneous coronary artery and peripheral arterial interventions.

Abstract
Infection of bare metal stents in the vasculature is rare, but associated with significant morbidity and mortality. We report two cases of bare metal stent infections and review the literature regarding infected bare metal stents with respect to risk factors, pathophysiology, diagnosis, treatment, and prevention. Overall, this article highlights the need to have a high index of suspicion of bare metal stent infection, since prompt diagnosis and treatment can ultimately decrease the morbidity and mortality associated with this devastating problem.

Abstract
BACKGROUND The preferential use of primary iliac stenting vs selective stenting is controversial. This study compares the early and late clinical outcomes of primary vs selective iliac stenting at our institution. METHODS A total of 110 consecutive patients with iliac stenosis (149 lesions) underwent primary stenting over a recent 5-year period (primary stent group). The early technical and clinical success and late clinical outcomes were compared with 41 patients (41 iliac lesions) who had percutaneous transluminal angioplasty (PTA) followed by selective stenting for suboptimal PTA (selective stent group). All patients were evaluated clinically and by duplex scanning with ankle-brachial indexes at 1, 6, and 12 months and every 12 months thereafter. RESULTS The perioperative complication rate for the primary stent group was 2.7% (three minor hematomas) vs 24% for the selective stent group (P < .0001). The overall early clinical success rate was 97% for the primary stent group vs 83% for the selective stent group (P = .002), however, the rate was 100% for short stenosis (A and B lesions <5 cm TASC classification) in both groups; in contrast to 93% for the primary stent group vs 46% for the selective stent group for longer stenoses (TASC - C and D lesions, P = .0003). The overall late clinical success was comparable for both groups: 88% for the primary stent group vs 80% for the selective stent group, however, this rate was superior for the longer lesions in the primary stent group, 84% vs 46% (P = .007). The primary patency rates at 1, 2, 3, and 5 years were 98%, 94%, 87%, and 77% for the primary stent group vs 83%, 78%, 69%, and 69% for the selective stent group (P = .030). These rates were comparable in both groups for shorter lesions: 100%, 98%, 98%, and 87% for the primary stent group vs 100%, 93%, 85%, and 85% for the selective stent group (P = .637). However, they were superior for the primary stent group in longer lesions: 96%, 90%, and 72% vs 46%, 46%, and 28% for the selective stent group at 1, 2, and 3 years (P < .0001). CONCLUSIONS The overall early clinical success rate was superior for the primary stent group. However, the initial (early) and late clinical success rates were comparable for short lesions (TASC - A and B lesions), but were inferior in selective stenting for longer lesions (TASC - C and D). Therefore, primary stenting should be offered to all TASC - C and D lesions.

Abstract
Percutaneous transluminal angioplasty and endovascular stent placement are becoming common techniques for iliac artery stenosis and obstruction that are intended to reduce the need for surgical bypass procedures. The usual complications include acute or subacute thrombosis, distal embolization, dissection, and extravasation. Although stent infection is very rare after stent replacement, it is reportedly associated with a high risk of morbidity and mortality, and the use of prophylactic antibiotics should be considered. We present a case of rupture of an infected pseudoaneurysm at the site of the external iliac artery that occurred 4 months after an uneventful percutaneous transluminal angioplasty and stent placement.

Abstract
OBJECTIVE This study describes the long-term results of endoluminal therapy for iliac in-stent obstructions. DESIGN This is a retrospective study. MATERIALS AND METHODS From 1992 to 2005, 68 patients (22 women), with a mean age of 61+/- 13 years and 16 bi-iliac in-stent obstructions, underwent 84 endovascular interventions for focal iliac in-stent stenoses (n = 61) or occlusions (n = 23). Primarily, only uncovered stents were placed. All patients were symptomatic: 70% had disabling intermittent claudication, 23% had resting pain, and 7% had trophic changes. All had in-stent diameter reduction exceeding 50% that was confirmed by duplex scanning and angiography. Procedures were performed under local anesthesia via the femoral route. RESULTS All interventions were initially technically successful, with a minor complication of pneumonia in one patient (2%). Initial clinical success was achieved in 86% of patients. PTA alone was used to treat 72 (86%) in-stent obstructions, the other 12 (14%) had PTA and renewed stent placement. The 30-day mortality rate was 0%. Mean follow-up was 35 months (range, 3 months to 10 years) and included duplex scanning. Primary clinical patency was 88% at 1 year, 62% at 3 years, and 38% at 5 years follow-up. During follow-up, 28 (33%) of 84 extremities required secondary reinterventions because of symptomatic renewed in-stent stenosis, and 11 were treated successfully with repeated endovascular interventions. Secondary patency at 1 year was 94%, 78% at 3 years, and 63% at 5 years. Surgical intervention was eventually needed in 17 (20%) of the 84 extremities. CONCLUSIONS Endoluminal therapy for iliac focal in-stent obstructive disease seems to be a safe technique with acceptable long-term outcome and therefore a true alternative to primary surgical reconstruction.

Abstract
An estimated 10 million people in the U.S. have symptomatic peripheral arterial disease (PAD); 20 to 30 million have asymptomatic PAD. The prevalence of intermittent claudication increases with age, affecting >5% of patients over 70. The incidence of claudication doubles or triples in patients with diabetes. As people grow older, symptoms from peripheral vascular disease increasingly limit daily activity. Until recently, vascular surgical procedures were the only alternative to medical therapy in such patients. Today, advances in minimally invasive percutaneous interventions have made endovascular procedures the primary modality for revascularization in most patients. Compared with open surgical procedures, endovascular interventions offer comparable or superior long-term rates of success with very low rates for morbidity and mortality. Furthermore, most of these interventions are performed on an outpatient basis, reducing hospital stays considerably. In this monograph we discuss current endovascular interventions for treating occlusive PAD, aneurysmal arterial disease, and increasingly common venous occlusive diseases.

Abstract
Our objective was to evaluate the impact of the ipsilateral superficial femoral artery (SFA) on percutaneous transluminal angioplasty (PTA) of the iliac arteries. From 1993 to 2005, 183 iliac lesions (179 stenoses, 4 occlusions; 37 common, 35 external, and 111 both iliac arteries) in 127 patients with disabling claudication [94 (52%)], rest pain [43 (23%)], and ulcer/gangrene [46 (25%)] were treated by PTA. TransAtlantic Inter-Society Consensus (TASC) iliac lesion types were A in 48 limbs (26%), B in 92 (50%), C in 38 (21%), and D in 5 (3%). Stents were placed selectively for primary angioplasty failure [residual stenosis (>30%) or pressure gradient (>5 mm Hg)]. Seventy-seven limbs (42%) had patent SFAs (66 intact/<50% stenosis and 11 previously bypassed, pSFA group), 28 (15%) had stenotic SFAs (50-99%, sSFA group), 51 (28%) had occluded SFAs (oSFA group), and 27 (15%) had concomitant SFA angioplasty (aSFA group). The Society for Vascular Surgery and the International Society for Cardiovascular Surgery reporting standards were followed to define outcomes. There were no perioperative deaths. Total complication rate was 1.1% (2/183, groin hematomas). The mean follow-up was 20 months (range 1-115). One hundred twenty-five limbs (68%) had PTA alone for iliac lesions, and 58 (32%) had iliac stenting (a total of 91 stents). TASC iliac lesion types and the status of the ipsilateral profunda femoris artery were not significantly different among the four groups. Seventeen limbs (9%) had subsequent infrainguinal bypass: three in the pSFA, seven in the oSFA, four in the sSFA, and three in the aSFA groups (p = 0.19). The primary patency rate was significantly decreased in the sSFA group (29% at 3 years, Kaplan-Meier log-rank, p < 0.0001) compared with the other three groups; however, there were no significant differences among the pSFA, oSFA, and aSFA groups (67%, 67%, and 86% at 3 years, respectively; p = 0.92). The continued clinical improvement rates were significantly decreased in the sSFA group (36% at 3 years, p = 0.0043) compared with the other three groups; however, there was no significant difference between the pSFA, oSFA, and aSFA groups (81%, 84%, and 75% at 3 years, respectively; p = 0.088). The assisted primary and secondary patency and limb salvage rates were not significantly different among the four groups (p > 0.40). Stratified analysis in patients with TASC type B/type C, critical limb ischemia, or claudicants revealed similar results. The primary patency and continued clinical improvement were significantly decreased in patients with stenotic SFAs, suggesting that concomitant SFA angioplasty might improve iliac patency after iliac PTA for patients with stenotic SFAs. The presence of an occluded SFA did not adversely affect the outcomes of iliac PTA. During iliac PTA, a stenotic SFA should be considered for revascularization via endovascular means but an occluded SFA can be observed.

Abstract
Objective We wanted to retrospectively evaluate the long-term therapeutic results of iliac arterial stent placement that was done in a single institution for 10 years. Materials and Methods From May 1994 to April 2004, 206 patients who underwent iliac arterial stent placement (mean age; 64±8.8) were followed up for evaluating the long term stent patency. Combined or subsequent bypass surgery was performed in 72 patients. The follow up period ranged from one month to 120 months (mean; 31±25.2 months). The factors that were analyzed for their effect on the patency of stents were age, the stent type and diameter, the lesion site, lesion shape, lesion length, the Society of Cardiovascular and Interventinal Radiology criteria, the total run off scores, the Fontaine stage and the cardiovascular risk factors (diabetes mellitus, hypertension and smoking). Follow-up included angiography and/or CT angiography, color Doppler sonography and clinical evaluation with the ankle-brachial index. Results Two hundred and eighty-four stents were placed in 249 limbs of 203 patients. The technical success rate was 98% (203/206). The primary patency rates of the stents at 3, 5, 7 and 10 year were 87%, 83%, 61% and 49%, respectively. One hundred seventy-seven patients maintained the primary stent patency until the final follow up and 26 patients showed stenosis or obstruction during the follow up. Secondary intervention was performed in thirteen patients. Lesions in the external iliac artery (EIA) or lesions in both the common iliac artery (CIA) and EIA were a poor prognostic factor for stent patency. The run off score and stent diameter also showed statistically significant influence on stent patency. The overall complication rate was 6%. Conclusion Iliac arterial stent placement is a safe treatment with favorable long term patency. Lesions in the EIA or lesions in both the EIA and CIA, poor run off vessels and a stent having the same or a larger diameter than 10 mm were the poor prognostic factors for long term stent patency.
