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

Abstract
The purpose of this multicenter study was to assess the long-term outcome of endovascular treatment of isolated atherosclerotic stenosis of the infrarenal abdominal aorta on the basis of clinical and ultrasound examination. Clinical, ultrasound, and angiographic findings from 36 women and 50 men (mean age, 53.2 years) treated for atherosclerotic stenosis of the infrarenal abdominal aorta were reviewed. Patients had claudication in 74 cases and rest pain in 4. Seven patients presented trophic manifestations and one had blue toe syndrome. Mean preoperative systolic index was 0.71. Mean diameter reduction was 77%. Circumferential calcification was partial in 36 cases (41%) and complete in 30 cases (35%). Percutaneous transluminal angioplasty was performed using the single-balloon technique in 60 cases and double-balloon technique in 26 cases. A stent was placed in 76 cases (88%) by necessity in 34% of cases (22 residual stenoses, 4 dissections). Completion angiographic findings were considered good in 82 cases (95%). The remaining four patients had residual stenosis with a diameter reduction >30%. One patient died during the immediate postoperative period from septicemia unrelated to treatment (early mortality, 1.2%). Aortic angioplasty was complicated by stent detachment from the angioplasty balloon in two patients, retroperitoneal hematoma in one, peripheral embolism in two, puncture-site hematoma in three, myocardial infarction in one, and thrombophlebitis of deep femoral artery in one patient (early morbidity, 9.3%). All patients underwent follow-up with clinical and hemodynamic evaluation (mean follow-up, 31 months). Actuarial survival at 3 years was 91%. Primary actuarial patency was 94% at 1 year, 89% at 3 years, and 77% at 5 years. Aortic restenosis occurred in seven patients and was treated by angioplasty in two, aortobifemoral bypass in four, and surveillance in one. Mean systolic index was 0.89. Statistical analysis of patency demonstrated no factor predictive of long-term complication. From the long-term follow-up findings in this study, we conclude that aortic angioplasty is a reliable minimally invasive technique for treatment of isolated atherosclerotic stenosis of the infrarenal abdominal aorta.

Abstract
OBJECTIVE evaluation and comparison of the endovascular treatment of isolated aortic and aortoiliac atherosclerotic lesions (stenoses and occlusions). METHODS a percutaneous endovascular procedure was performed in 52 patients (38 men and 14 women) with a mean age of 52 years (range, 25-85 years). The baseline angiogram showed 35 aortic lesions (31 stenoses, 4 occlusions) and 17 aortoiliac lesions (14 stenoses, 3 occlusions). Percutaneous techniques used in this series included variable combinations of transluminal angioplasty and stenting. All stents placements were performed over-the-wire using the transfemoral route (most often bilateral approach). Clinical examination and Duplex-scan were performed at discharge, 1 month, 6 months, 12 months, and then yearly. RESULTS technical success was 100% for aortic and aortoiliac lesions. Angiographic success rates were comparable for aortic (91%) and aortoiliac (94%) lesions. No death occurred during or early after the endovascular intervention. Duplex-scan confirmed 100% patency rate at discharge. There was no significant difference between the aortic (94%) and aortoiliac (96%) groups regarding immediate clinical improvement. Mean follow-up was 34+/-31 months (range, 0-130 months). The cumulative primary patency rate at 36 months was 85% in the aortic group and 86% in the aortoiliac group. Clinical success, defined as a symptom-free status at the end of follow-up, was also similar in both groups. CONCLUSION endovascular treatment of isolated aortic lesions of the infra-renal aorta has favorable outcomes comparable to those of aortoiliac lesions.

Abstract
PURPOSE To evaluate the long-term clinical and hemodynamic effectiveness of aortic stent placement in cases of failure of intended infrarenal percutaneous transluminal aortic angioplasty (PTAA). MATERIALS AND METHODS Fifty-three patients who underwent technically successful PTAA were compared with 24 patients who underwent aortic stent placement because of PTAA failure (19 patients) or ulcerated lesions (five patients) that otherwise would have been treated surgically because of the embolization hazard associated with PTAA alone. Clinical patency was defined as the absence or improvement of symptoms after the intervention. Hemodynamic patency was defined as a normal Doppler waveform in the common femoral arteries, an ankle-brachial index greater than 0.95, or the absence of a thigh-brachial pressure gradient. RESULTS Three-year clinical and hemodynamic patency rates, respectively, were 85% and 79% for PTAA and 69% and 43% for aortic stent placement. No morbidity was encountered. With use of the Cox proportional hazards model, two significant risk factors were retained for restenosis: unchanged smoking habit (P =.04) and small dilatation diameter (P =.001). Aortic stent placement, performed in patients with a smaller aortic diameter (10.3 vs. 12.7 mm for PTAA), appeared to be a predictive factor for restenosis by using univariate analysis. By using the Cox proportional hazards model, however, the restenosis rates after PTAA and aortic stent placement were not significantly different. CONCLUSION When aortic diameter is taken into consideration, there is no evidence that clinical outcome after secondary aortic stent placement would be poorer than technically successful PTAA.

Abstract
PURPOSE To present a rare case of chronic total occlusion of the infrarenal aorta treated with a self-expanding endoluminal stent implanted without preliminary dilation. METHODS AND RESULTS A 68-year-old woman presented with severe bilateral buttock and thigh claudication. Angiography revealed total occlusion of the infrarenal abdominal aorta and relatively normal iliac vessels. Via a right groin puncture and a 9-F sheath, a 14-mm x 5-cm self-expanding Wallstent was deployed in the abdominal aorta and expanded with an angioplasty balloon. Completion angiography showed successful recanalization of the aorta with satisfactory distal flow. Palpable distal pulses were restored, and the patient's symptoms were alleviated. She remained asymptomatic until her death from a major stroke 11 months after aortic stent implantation. CONCLUSIONS Primary stenting may be considered a viable alternative to conventional surgery in selected patients with total infrarenal aortic occlusion.

Abstract
A 55-year-old woman presented with an ulcerative stenosis of the distal abdominal aorta. She was scheduled to undergo percutaneous aortic balloon angioplasty the next day. Upon readmission, however, she complained of lower abdominal pain. A second abdominal angiogram revealed thrombosis of the infrarenal abdominal aorta and left common iliac artery. This was treated by means of simple transcatheter thrombus aspiration and thrombolysis, followed by stenting of the aorta.

Abstract
PURPOSE To evaluate the results of primary stenting in aortic occlusive disease. METHODS Thirty patients underwent primary stenting of focal concentric (n = 2) and complex aortic stenoses (n = 19), and aortic or aorto-iliac occlusions (n = 9). Sixteen patients underwent endovascular outflow procedures, three of whom also had distal open surgical reconstructions. Median follow-up was 16 months (range 1-60 months). RESULTS Guidewire crossing of two aorto-biiliac occlusions failed, resulting in a 93% (28/30) technical success. Major complications included one access hematoma, one myocardial infarction, one death (recurrent thromboembolism) in a patient with widespread malignancy, and one fatal hemorrhage during thrombolysis of distal emboli from a recanalized occluded iliac artery. One patient did not improve his symptoms, resulting in a 1-month clinical success of 83% (25/30). Following restenting the 26 stented survivors changed their clinical limb status to +3 (n = 17) and +2 (n = 9). During follow-up one symptomatic aortic restenosis occurred and was successfully restented. CONCLUSIONS Primary stenting of complex aortic stenoses and short occlusions is an attractive alternative to conventional surgery. Larger studies with longer follow-up and stratification of lesion morphology are warranted to define its role relative to balloon angioplasty. Stenting of aorto-biiliac occlusions is feasible but its role relative to bypass grafting remains to be defined.

Abstract
PURPOSE The purpose of this study was to determine the early and long-term results of percutaneous transluminal angioplasty (PTA) of atherosclerotic lower abdominal aorta stenosis. METHODS This study was performed as a retrospective study. From 1980 to 1997, 46 patients with chronic lower limb ischemia with moderate to severe claudication as the result of isolated infrarenal disease or aortoiliac disease underwent PTA. All patients underwent angiography before and after angioplasty and Doppler ultrasound scan examination with ankle-brachial index determination. No stents were used. RESULTS The technical success rate was 96% (44 of 46 cases). Thirty-eight patients (83%) immediately showed clinical, hemodynamic, and angiographic improvement. The initial success rate for patients with isolated infrarenal or bifurcation disease was 92%, whereas it was 71% for aortoiliac disease. Among the eight patients with no initial improvement, four had clinical deterioration and two required emergency surgical revascularization. There were no other complications. Fifty-six percent of the patient conditions (95% confidence interval [CI], 38% to 74%) remained clinically improved at the 5-year follow-up examination. Recurrence of symptoms was caused by femoropopliteal disease in most patients. The primary patency rate assumed with maintenance of hemodynamic improvements was 70% (95% CI, 52% to 88%) and 64% (95% CI, 44% to 84%) at 4 and 5 years of follow-up, respectively. The primary patency rate at 4 years for patients with isolated infrarenal or bifurcation disease was 83% (95% CI, 64% to 100%), whereas it was 55% for aortoiliac disease (95% CI, 30% to 80%; P =.06) The variables that were statistically predictive of patency failure were poor runoff (P =. 01) and presence of aortoiliac atherosclerotic disease (P =.04). CONCLUSION Our results suggest that PTA is an excellent treatment for chronic arterial insufficiency of the lower extremities as the result of isolated atherosclerotic lower abdominal aortic occlusive lesions because of good long-term patency. Aortic PTA for those patients with iliac involvement or with poor runoff gives acceptable results but carries lower patency and clinical success rates.

Abstract
This report describes an in-stent restenosis of the infrarenal aorta in a patient with Takayasu's arteritis in a nonactive state. A 10-mm-diameter Wallstent had been deployed 42 months previously. The stented restenosed segment was replaced by a surgical graft. Histopathological examination of the excised aortic segment showed a thin layer of fibrocellular neointima and massive organized and calcified thrombus. To our knowledge, this is the first histopathological report of a late in-stent restenosis of the abdominal aorta in Takayasu's arteritis.

Abstract
AIM To evaluate the short-term results of percutaneous stent placement in treating stenosis in the aorta caused by non-specific aortitis (Takayasu's disease). METHOD Five patients were treated by this method, all of whom had uncontrolled hypertension, haemodynamically significant stenosis in the aorta and a clinically inactive disease. Stents were placed to treat an obstructing dissection in four and recurrent stenosis in one patient. All procedures were carried out via the percutaneous transfemoral route, utilizing self-expanding stents. RESULTS The lesion was located in the thoracic aorta in three patients and in the abdominal aorta in two patients. The stenosis decreased from 81+/-2 to 7+/-3%, the pressure gradient fell from 97+/-5 to 9+/-2 mmHg, the blood pressure improved from 200+/-3/124+/-2 to 131+/-2/81+/-2 mmHg, and the drug requirement fell from 4+/-.2 to 1.3+/-.3 (P value for all <0.001). No complication was encountered. At follow-up at 13+/-4 months, all of the patients had improved clinically. Intimal hyperplasia within the stent was seen in two patients who underwent follow-up angiograms. CONCLUSION Percutaneous aortic stenting is useful in treating selected patients with non-specific aortitis. Further information about the long-term behaviour of intimal hyperplasia and the response of stented segments to the aging process needs to be understood before elective stenting in this young patient population can be advocated.

Abstract
PURPOSE To compare intravascular ultrasound (IVUS) and angiography with histology in determining the degree of stent stenosis in an in vivo experiment. METHODS In 16 sheep, a total of 64 stents were implanted into the external iliac arteries. Two stents were inserted on either side. Patency was followed by angiography and IVUS. Four types of stent were used: two Dacron-covered (Cragg Endopro and heparinized Cragg Endopro) and two noncovered (Cragg and Memotherm stents). Eight animals were killed after 1 month, eight others after 6 months. Histological sections were prepared from the stented vessels. Measurements of the patent and total stent diameters determined by IVUS, angiography, and histology were compared. RESULTS Correlation between IVUS and angiography was 0.75, between IVUS and histology 0.77, and between angiography and histology 0.85. A mean stent stenosis of 17 +/- 11% (range 0-51%) was found on angiography, of 10 +/- 11% (0-46%) on IVUS, and of 20 +/- 11% (4%-49%) on histology. In comparison with histology, IVUS underestimated the degree of stenosis by 10 +/- 8%, and angiography underestimated it by 3 +/- 6%. Resolution of IVUS was calculated to be about 0.35 mm and that of angiography to be about 0.15 mm. CONCLUSION Under experimental conditions, IVUS was not superior to angiography in determining the degree of stent stenosis in long-segment stenoses of iliac artery stents, when measurements were correlated with histology. Angiography is sufficient for following the patency of iliac artery stents.

Abstract
PURPOSE To retrospectively compare the safety and short-term efficacy of conventional percutaneous transluminal angioplasty (PTA) and PTA with the Palmaz balloon-expandable intravascular stent for the treatment of infrarenal abdominal aortic atherosclerotic stenoses. PATIENTS AND METHODS The records of 25 patients with infrarenal aortic stenoses treated by means of percutaneous techniques were retrieved from the SCVIR Transluminal Angioplasty and Revascularization (STAR) Registry and analyzed. Thirteen patients were treated with PTA alone and 12 were treated with the Palmaz intravascular stent. RESULTS Technical success was achieved in 92% of patients treated with PTA alone and in 100% of those treated with the Palmaz stent. Significant improvements in lesion morphology, hemodynamics, clinical status, and ankle arm indexes were shown in both groups. There was no statistically significant difference in percent stenosis reduction, decrease in trans-stenotic gradient, or initial clinical outcome between the group treated by means of PTA and the group treated by means of PTA with the Palmaz stent. CONCLUSIONS PTA and intravascular stent placement of atherosclerotic stenoses involving the infrarenal aorta are both safe and efficacious therapeutic modalities. At present, it does not appear that primary stent placement confers any short-term benefits over technically successful PTA in aortic stenoses.

Abstract
PURPOSE To retrospectively review and to report the results of stent placement for focal mid-abdominal aortic stenoses. MATERIALS AND METHODS During a 4-year period, 10 focal mid-abdominal aortic stenoses were treated with stent placement in nine patients (six women and three men; mean age, 61 years; range, 49-73 years). All of the stenoses were atherosclerotic in nature except for one at the proximal anastomosis of an aortobi-femoral graft, which may have been from fibrointimal hyperplasia. Seven of the 10 stenoses were treated with primary stent placement, whereas three were treated with stent placement after suboptimal angioplasty. RESULTS The technical success rate was 100%. Clinical success, defined as complete elimination or improvement of symptoms present before stent placement, was achieved in eight of the nine patients with a mean duration of follow-up of 1.6 years (range, 0.2-3.0 years). CONCLUSION In view of the excellent technical and clinical success, the authors believe that stent placement should be considered as an adjective therapy to angioplasty or as a primary method of treatment in properly selected patients with focal mid-abdominal aortic stenoses.

Abstract
The aim of this report is to review the current state of the art with respect to noncoronary vascular stenting. A review of the literature was performed, examining the historical aspects of stent design and usage, as well as the currently available designs and their respective functions. When appropriate, we note our personal experience with stent placement in each anatomic site. Currently available stents take many forms: balloon-expandable, self-expanding, and shape-memory alloy. Varied design modifications have been made to maximize the open area, to limit the surface area of the prosthesis, to increase (or decrease) flexibility, and to increase (or decrease) stent plasticity and elasticity. Modifications to minimize thrombogenicity are also underway. The clinical uses of the currently available stents in multiple anatomic locations will be discussed. Intravascular stents are an addition to the arsenal available for prolonging blood vessel patency.

Abstract
Intravascular stent placement in Pediatric Cardiology has provided one of the most interesting and effective means of catheter treatment of congenital lesions. In the 5 years since it has been performed, balloon-expandable stent placement has provided relief of many previously untreatable vascular stenoses and has resulted in improvement of blood flow, reduction of right ventricular pressure and, in many cases, dramatic improvement of symptoms. In this article, the background of balloon-expandable stent placement is discussed, and specific observations are offered regarding the technique of implantation. The generally excellent results are presented and a number of novel problems and pitfalls are outlined. Finally, a brief summary of the wide ranging applicability of stent implantation is discussed, along with some of the important and imaginative new directions for the therapy.

Abstract
Balloon rupture is a known technical problem with implantation of vascular stents. In most cases, the ruptured balloon can be retrieved with simple maneuvers. In this case report, a peripheral balloon became trapped within an undeployed peripheral vascular stent and could not be removed by application of standard maneuvers. A novel approach to balloon retrieval was devised and undertaken with success.

Abstract
From March 1990 to May 1991, arterial stents were placed in seven patients because of a tight stenosis (five patients) or a total chronic occlusion (two patients) located in the infrarenal aorta. In one case, the aortic occlusion extended to both common iliac arteries. After balloon dilatation, aortic stents were successfully positioned in all cases. Bilateral common iliac recanalization and stent placement were performed in one case. No complications occurred in any of the patients. No complications occurred in any of the patients. Follow-up data were derived from clinical assessments and angiographic results. After a 15.1-month mean follow-up period (range 12-24 months), the seven aortic stents remained patent. Three iliac artery procedures were performed in two of the patients as well. Claudication recurred in three of the seven patients which was related to a common iliac occlusion (one case) or distal progression of atherosclerosis (two cases). Aortic stents seem to be suitable for treating failed angioplasty of aortic lesions but the procedure remains technically difficult when there is associated severe atherosclerosis of the proximal common iliac arteries. Nevertheless, considering the morbidity rate (0%) and the patency rate in this series, this technique could become an alternative to surgical treatment for infrarenal aortic occlusive lesions.
