Reconstruction Of Femoral Artery Research Articles

Covered Endovascular Reconstruction of the Iliac Artery Bifurcation (CERIB).

The aim of this study was to present the covered endovascular reconstruction of the iliac artery bifurcation (CERIB) technique as a revascularization option for aorto-iliac occlusive disease (AIOD) involving the iliac artery bifurcation. This was a retrospective single-center study including all patients undergoing a CERIB procedure from January 2021 until December 2022. Covered endovascular reconstruction of the iliac artery bifurcation procedures were performed percutaneously with bilateral femoral access, excepting cases where simultaneous open femoral artery reconstruction was required due to the extension of peripheral arterial occlusive disease. Standard patient, procedural, and follow-up (FU) data including survival and arterial reinterventions were gathered and analyzed. A total of 13 patients were included (11/13 male, median age=70 [60-76] years). Additional open and/or endovascular procedures included endarterectomy of the femoral bifurcation (n=6), rotational atherectomy (n=2), and 1 axillary artery cutdown for upper limb access (n=1). Median operating time was 2.9 hours (1.5-4.9 hours); median radiation duration and dose were 28.4 (14.3-63.3 minutes) and 4090.6 (384.4-9430.1 cGray/cm2), respectively. The stent grafts used for CERIB were BeGraft peripheral n=31, BeGraft Aortic n=4 and BeGraft peripheral plus n=1 (Bentley InnoMed GmbH, Hechingen, Germany). In 2 patients with prior stenting of the common iliac artery (CIA), only the internal and external iliac arteries (IIA and EIA) were treated in this study, and in 2 cases, additional uncovered stents were required for relining. Technical success was 100%. During a midterm FU (median 18 [4-31] months), 2 patients died from cardiovascular reasons and 1 patient with prior iliac stenting required reinterventions for recurring occlusion. Covered endovascular reconstruction of the iliac artery bifurcation is a straightforward option for treating AIOD involving the iliac artery bifurcation that allows preservation of internal iliac artery perfusion and shows good early and midterm results. Prior iliac artery stenting may be a risk factor for early occlusion after CERIB. Aorto-iliac occlusive disease with involvement of the internal iliac artery is encountered regularly in vascular surgical practice, but the internal iliac artery is often not included in the revascularization strategy. The present article will increase the awareness for the relevance of including the internal iliac artery in revascularization strategies and presents CERIB as another method to be added to the armamentarium of (endo-)vascular surgeons and interventionalists.

Choice of hybrid interventions for iliac-femoral arterial lesions

To compare the short-term and long-term outcomes of hybrid interventions after various infrainguinal reconstructions (restoration of blood flow through superficial femoral artery and pulsatile blood flow through deep femoral artery) in patients with iliac-femoral arterial disease. A retrospective analysis included patients after hybrid iliac-femoral interventions between 2014 and 2018. These interventions included stenting of iliac arteries and various open infrainguinal reconstructions. The first group (n=41) consisted of patients who underwent reconstruction of superficial femoral artery, the second group (n=88) - restoration of pulsatile blood flow in deep femoral artery. We analyzed the Rutherford score, perioperative complications, primary patency rates and limb salvage rates after 12 months in both groups. Significant improvement (Rutherford score +3) was achieved in 28 (70%) and 14 (15.9%) patients, respectively (p<0.05). There were no significant between-group differences in the number of postoperative complications. Surgery time was longer in the first group (median 160 and 130 min, respectively, p<0.05). However, intraoperative blood loss was similar. Primary patency rates after 12 months were 82.4% and 95.1%, respectively (p=0.054). Limb salvage rates after 12 months were 94.7% and 100%, respectively (p<0.05). This study highlights the potential advantages of restoring pulsatile blood flow through the deep femoral artery in hybrid interventions. Higher primary patency and limb salvage rates in the second group indicate better long-term outcomes after restoration of blood flow through the deep femoral artery. Further prospective studies are needed to confirm these results and determine the underlying mechanisms of differences.

Management of large post-crossover inguinal lymphocele

A 73-year-old man with a history of peripheral arterial disease and previous bilateral common femoral artery reconstruction presented with left foot critical limb-threatening ischaemia and underwent right to left femoro-profunda crossover grafting. Postoperatively, he developed a left groin lymph leak that initially dried up but later re-presented as a very large lymphocele. Initial attempts with aspiration on three occasions and then surgical drainage with sac excision and ligation of long saphenous lymphatics did not lead to resolution. Subsequently, a hybrid approach using percutaneous lymphangiography and drainage, sclerotherapy (bleomycin, then absolute alcohol) and eventual identification and ligation of the afferent lymphatic channel resulted in resolution of the lymphocele without untoward side effects, sepsis or compromise of the revascularisation.

Surgical Approach of an Infected Saphenofemoral Looped PTFE Graft Arteriovenous Fistula and Arterial Reconstruction with Cryopreserved Allograft

Introduction: Autologous arteriovenous fistula is still the most popular vascular access for hemodialysis [1]. There have been few reports of saphenofemoral arteriovenous fistulas over the last 10 to 20 years because of suggestions of high morbidity, poor patencies and needling difficulties [2]. Some disadvantages of using this access are the necessity for a more extensive and deeper dissection using larger vessels and greater susceptibility to infection and steal syndrome [3, 4]. Attention should be paid to the patient's vasculature before surgery, through the "maturation" phase and chronic use [5]. Case report: A 72-year-old female with a history of arterial hypertension, diabetes mellitus and chronic renal failure requiring three-weekly hemodialysis, with a 4-day history of a painful and hot mass in the right thigh, fever, and hemoglobin decline. Physical examination: hematoma at the right inguinal region, presence of a tourniquet, femoral pulse 2/2 and not assessable distal pulses due to edema; coldness, and increased capillary refill. Aortoiliac and lower limb angiotomography showed: ruptured pseudoaneurysm of the right common femoral artery, ipsilateral superficial femoral artery injury and prosthetic femoral arteriovenous fistula infection. Open emergency approach through an infra-inguinal longitudinal incision was performed, draining a large hematoma and pus, finding an infected prosthetic PTFE graft from a saphenofemoral loop fistula with injury of the right superficial femoral artery and active bleeding at the site, plus dehiscence of saphenous anastomosis. Thrombectomy of the superficial and common femoral artery, en bloc arteriotomy of the right superficial femoral artery and arterial reconstruction with a cryopreserved arterial allograft with end-to-end anastomosis was performed. A Vacuum Assisted Therapy (VAC® ) system was created to cover the surgical site. Patient deceased from hypovolemic shock. Conclusions Unusual site AVFs (i.e., saphenofemoral loop graft AVFs) should be carefully followed-up to reduce the risk of complications and raise the awareness to diminish associated morbidity and mortality. An arterial cryopreserved allograft may be used for arterial reconstruction in the setting of an infected wound. The goal must be to spread more knowledge in this critical area of medicine that is importantly affecting medical costs of renal replacement therapies and patients' quality of life and survival rates.

Repair of Femoral and Popliteal Artery Aneurysms

Femoral and popliteal artery aneurysms constitute most peripheral aneurysms. In general, with both femoral and popliteal artery aneurysms, elective repair and reconstruction tend to be associated with significantly better postoperative outcomes than emergency repair undertaken after a limb-threatening complication. Specific treatment decisions may be influenced by the presence or absence of symptoms of aneurysmal disease. For femoral artery aneurysms, this chapter presents the preoperative evaluation, operative planning, operative technique (endovascular repair, ultrasound-guided compression, and open surgical repair), and outcome evaluation. For popliteal aneurysms, this chapter discusses the preoperative evaluation, operative planning (indications for repair and preoperative arterial thrombolysis), operative technique (open vs. endovascular repair), and outcome evaluation (dependent on whether surgical or endovascular). This review contains 15 figures, 9 tables, and 41 references.

Outcomes of Selective Strategies for Distal Entry Tears After Thoracic Endovascular Aortic Repair in Type B Aortic Dissection

Distal entry tears have undesirable influence in type B aortic dissection (TBAD) after thoracic endovascular aortic repair (TEVAR), including inhibition of aortic remolding and increase of late aortic events. Therefore, distal entry tears should be managed. Nowadays, main strategies for managing distal entry tears included total and selective strategies. However, which strategy is better still remains controversial. The objective of the study is to investigate the outcomes of selective strategy for distal entry tears after TEVAR in TBAD. A total of 43 consecutive patients with TBAD with distal entry tears after TEVAR were administered with selective strategy for distal entry tears, including occlusion of the tear in the thoracic aortic segment, thrombosis of the reverse blood flow channel in the false lumen, and selective occlusion of distal entry tears. Mortality, complications, and aortic remolding in early follow-up (12months after operation) were analyzed. All 43 patients survived during the follow-up period. Operation was performed again for femoral artery reconstruction in 1 patient who had occlusion of the approach vessel during the follow-up period, and the remaining 42 patients had no uncomfortable symptoms and operation-related complications. The maximum diameter of the aorta was 32.03±6.35 mm and 27.36±4.92 mm, respectively, for before and after reintervention, and the difference was significant (t=5.899, P<0.001). The unthrombotic range of the false lumen after reintervention was significantly shrunken in all patients, compared with the range before reintervention. Selective strategy was safe and effective, at least in early follow-up. Its effectiveness should be further verified by more clinical observation results and long-term follow-up results.

The rectus femoris muscle flap is an underused tool in the vascular surgeon's armamentarium

Mrs Havercamp aFictitious.aFictitious. presents to clinic at 4:00 pm today for an unscheduled appointment. She is a 67-year-old obese diabetic woman who is 10 days status post right common femoral endarterectomy with Dacron patch angioplasty and retrograde iliac stenting for rest pain. Today, she reports increasing pain and drainage from the groin wound. On examination, there is erythema and dehiscence of the skin edges. Cloudy fluid emanates from the wound. I sigh. “Mrs Havercamp, when was the last time you had anything to eat or drink?” Groin wound complications—alarmingly common, occasionally lethal. Amputation may result, but regardless of the outcome, a significant commitment of time, effort, and cost ensues for the patient and the surgeon. That muscle flaps are a valuable adjunct in the treatment of groin wound complications is incontrovertible. Virtually every vascular surgeon has rotated a sartorius flap, usually with success. But what if the sartorius flap fails? or is unavailable? Most of us will have exhausted our toolbox and require the assistance of a plastic surgeon colleague. Indeed, there are myriad reports of other types of muscle flaps used in the management of groin wounds—tensor fascia lata, gracilis, anterolateral thigh myocutaneous, rectus femoris, rectus abdominis, and others. Common among these reports is that they are performed by plastic surgeons in the majority of cases. This study by Ryer and colleagues1Ryer E.J. Garvin R.P. Kapadia R.N. Jorgensen B.D. Green J.O. Fluck M. et al.Outcome of rectus femoris muscle flaps performed by vascular surgeons for the management of complex groin wounds after femoral artery reconstructions.J Vasc Surg. 2020; 71: 905-911Abstract Full Text Full Text PDF PubMed Scopus (3) Google Scholar describes 24 rectus femoris flaps performed exclusively by vascular surgeons for treatment of complex groin wounds after femoral artery reconstruction. As expected, obesity, diabetes, and chronic real disease were common in this cohort of patients, and more than half of the surgical procedures were performed in fields previously operated on. Outcomes were largely favorable and comparable to other publications for patient survival and limb salvage. There were no instances of flap necrosis, nor were any complications related to flap rotation identified. The technique for creation of these flaps is described and is straightforward. The authors acknowledge a potential disadvantage of the rectus femoris flap: a decrement in knee extension strength. The authors did not attempt to quantify it, and they appear to dismiss its importance among chronically ill patients who engage in little strenuous activity. On the contrary, maintaining all residual strength among these patients whose reserve is marginal may be critically important to maintaining mobility. This study sheds no light on this issue. In addition, harvesting and rotating this flap almost certainly take more time than creating a sartorius flap and do involve a fairly generous counterincision in the thigh. Nevertheless, I suspect that these potential downsides practically have little impact. Will I abandon the sartorius flap? Certainly not, and I suspect the authors will not either. There is clearly a role for this simple flap under the right circumstances. Will I add the rectus femoris flap into my own armamentarium? Absolutely.

Hybrid Common Femoral Artery Surgical Revascularization Associated to Endovascular Femoropopliteal Recanalization in High-Risk (ASA 3 - 4) Patients: A Seven-Year Period Institutional Experience

Objective: The present study was conceived to analyze the clinical benefit of hybrid interventions with surgical common femoral artery (CFA) reconstruction coupled to superficial femoral/popliteal endovascular recanalization for severe infrainguinal multilevel occlusive disease in high-risk ASA Class 3 - 4 patients. Material and Methods: From August 2008 until May 2015, a series of 143 hybrid infrainguinal interventions in 124 ASA Class 3 - 4 patients were performed in our department for Rutherford category 2 - 6 ischemic presentations. Patient demographics, specific risk factors, technical characteristics and patency results were retrospectively examined during a mean 36.8 months of follow-up. In a majority of 94 limbs (65%), the endovascular stage of interventions focused on long (>15 cm) femoropopliteal occlusions in parallel to regular CFA surgical revascularization. Two or three runoff tibial trunks were evinced in 84% cases, while one or none permeable vessel was found in 23 (16%) limbs. Results: Inasmuch surgical approach was successful in all cases, the endovascular stage was technically profitable in 134 (93%) cases. The ABI posto-peratively improved (>1.5) in 73% of cases, while clinical presentation gained at least one Rutherford category in 89% limbs. The mean hospital stay was 6.1 days (3 - 12 days) whereas the 30-day mortality rate in this homogeneous “high-risk” group of patients was 3.2%. Global risk factors alike age (>70 years/p = 0.0005), smoking ((p = 0.0170) and female gender (p = 0.0111), together with CTOs length (>15 cm/(p = 0.0470), severe calcifications (p = 0.0001), poor tibial runoff (p = 0.0001), TASC “C” and “D” lesions (p = 0.360 and (p = 0.0394), the stent number ((n = 3) and length (>6 cm) ((p = 0.0039 and (p = 0.0003) and the initial ABI scoring ((p = 0.0051) showed statistical negative influence on primary patency. Conclusion: Hybrid infrainguinal revascularization may afford useful results in selected ASA “high risk” patients, owning low invasiveness, reproducibility and acceptable patency in return to punctual postoperative surveillance.

Midterm Outcomes After Prearteriotomy Guidewire Access (PAGA) With Antegrade Recanalization in Patients With Extensive Aortoiliofemoral Occlusive Disease Without the Use of a Re-entry Device

A prearteriotomy guidewire access (PAGA) was described to treat bulky iliofemoral occlusive disease. A wire is passed first from the groin into the aorta, before the arteriotomy, to increase technical success. Achieving retrograde intraluminal access in extensive aortoiliofemoral occlusive disease (AIFOD) can be a challenge. We modified the PAGA technique to successfully recanalize extensive aortoiliofemoral occlusion performed with adjunctive femoral artery reconstruction as an alternative to extra-anatomic bypass in high-risk patients for aortobifemoral bypass. We approach these cases via a left brachial approach and groin cutdown. Once brachial access is obtained, the patient is systematically heparinized. Then, a 90-cm destination sheath is placed in the distal aorta. A stiff glidewire and a guide catheter are used to recanalize the chronic AIFOD. The wire is passed in an antegrade fashion across the AIFOD all the way toward the femoral head. A femoral arteriotomy is done to capture the wire, thus establishing access from the groin into the patent aorta. External iliac artery and femoral artery endarterectomy is performed around the wire. The wire is passed through the patch before the patch angioplasty is completed. Once femoral revascularization is done, a sheath is placed over the wire, and retrograde iliac stenting is performed to the level above the patch to avoid crossing the inguinal ligament. This procedure has been performed in 18 patients (13 with critical limb ischemia, 5 with claudication) with 94.4% technical success, without the use of a re-entry device. Four patients required an interposition graft, and 14 (77.8%) required femoral endarterectomy with patch angioplasty. The procedures in 10 patients (55.5%) were done under spinal anesthesia. All patients had significant cardiopulmonary comorbidities, and five had had multiple abdominal surgeries. One patient (5.5%) required oral antibiotics to treat a superficial wound infection. One patient (5.5%) died ≤30 days (massive myocardial infarction), and one patient required an axillobifemoral bypass at 6 months for acute stent occlusion. The remaining 17 patients were symptom free, with patent stents, at a mean of 16.5 months (range, 12-22 months). Modified PAGA can be used to safely revascularize high-risk patients with extensive AIFOD, with acceptable complication rate and patency. This procedure is currently offered to patients with aortoiliofemoral disease, not candidates for aortobifemoral bypass, instead of an extra-anatomic bypass.

Surgical Management of a Deep Femoral Artery Aneurysm

Standard surgical methods for managing true aneurysms of the deep femoral artery have not been established because these aneurysms are rare. An 85-year-old man, who had a ruptured aneurysm of the deep femoral artery, underwent aneurysmectomy and distal reconstruction with a contralateral autologous vein graft. Three-dimensional computed tomography is a valuable diagnostic modality to evaluate synchronous aneurysms and peripheral arterial circulation for treatment planning. Because of their etiology, aneurysms of the deep femoral artery should be treated with revascularization when technically feasible, even if the superficial femoral artery is patent. A contralateral saphenous vein may be the preferred conduit because ipsilateral venous stasis is likely.

Spiral saphenous vein grafts in the femoral artery and vein reconstruction

Autogenous vein grafts have become the first choice with their positive outcomes in vascular injuries and are quite widely used today. Particularly in the case of size mismatch, spiral saphenous vein grafts prepared from the saphenous veins have had encouraging results. Two cases in which the patients had vascular reconstructions with spiral saphenous vein grafts for a stab wound and gunshot injury are presented in this paper.

Chronic ischaemic leg ulcer as a late complication of post-traumatic arteriovenous fistula

Chronic post-traumatic arteriovenous fistula (AVF) is a late complication of vascular injury and can be presented with symptoms of congestive heart failure, venous hypertension and distal ischaemia. We present an unusual case of chronic ischaemic leg ulcer in young adult caused by post-traumatic AVF. Case report A 29-year-old male patient was admitted to our hospital with symptoms of chronic ulcer located on the lateral side of the lower left leg. Arterial pulses distally from the groin were absent. His medical history revealed him to have sustained gunshot injury of the left thigh in the war conflict 18 years before. Angiography showed a large AVF between superficial femoral artery and femoral vein. The patient underwent surgical repair of AVF with reconstruction of superficial femoral artery by saphenous vein interposition under spinal anaesthesia. Completion angiography confirmed AVF exclusion. Leg ulcer healed within a month. Chronic leg ulcer may be the only symptom of large post-traumatic AVF in young adults.

Congenital-idiopathic superficial femoral artery aneurysm in a 7-year-old child

Superficial femoral artery aneurysm in children is distinctly uncommon, and usually results from infection, vasculitis, connective tissue disorder, or trauma. We report a 7-year-old girl who had multiple fusiform aneurysms of the right superficial femoral artery, with no evidence of related disorders. The patient successfully underwent aneurysm resection and femoral artery reconstruction with autogenous saphenous vein. Histologic examination revealed intimal thickening with fibroplasia without severe inflammatory infiltrates or cystic medial necrosis, suggesting a congenital-idiopathic arterial aneurysm. Three years after the procedure, the saphenous vein graft is fully patent and the patient is in good condition.

Incidence and Survival Outcome Following Femoral Artery Reconstruction During Endovascular Abdominal Aortic Aneurysm Repair

Planned or unplanned reconstruction of the common femoral artery (femoro-femoral crossover and/or patch closure) may be required following endovascular abdominal aortic aneurysm repair (EVAR) stent graft deployment for arterial closure or maintenance of limb perfusion. The aim of this study was to examine the incidence of common femoral artery reconstruction (FAR) following EVAR and examine the effect on patient survival. A total of 178 patients undergoing EVAR were studied retrospectively. In all, 31 patients (17.4%) underwent FAR; 16 (51.6%) femoro-femoral crossover, and 15 (48.4%) endarterectomy and patch closure. All cause survival in patients undergoing FAR was significantly poorer than those undergoing direct closure (P = .010).A total of 3 factors: the need for FAR (hazard ratio [HR] = 0.435, P = .006), chronic obstructive pulmonary disease ([COPD] HR = 0.424, P = .002), and abdominal aortic aneurysm (AAA) size (HR = 1.414, P = .005) were significantly and independently associated with survival on forward conditional analysis. Femoral artery reconstruction was performed in almost 1 in 5 patients undergoing EVAR and associated with decreased survival. Multidisciplinary teams should be aware of these findings when planning EVAR, especially in borderline candidates.

Limb ischemia after common femoral artery cannulation for venoarterial extracorporeal membrane oxygenation: an unresolved problem

Purpose Extracorporeal Life Support Organization Registry data confirm that the number of pediatric patients being supported by extracorporeal membrane oxygenation (ECMO) is increasing. To minimize the potential neurologic effects of carotid artery ligation, the common femoral artery (CFA) is frequently being used for arterial cannulation. The cannula has the potential for obstructing flow to the lower limb, thus increasing ischemia and possible limb loss. We present a single institution's experience with CFA cannulation for venoarterial (VA) ECMO and ask whether any precannulation variables correlate with the development of significant limb ischemia. Methods We reviewed all pediatric patients who were supported by VA ECMO via CFA cannulation from January 2000 to February 2010. Limb ischemia was the primary variable. The ischemia group was defined as the patients requiring an intervention because of the development of lower extremity ischemia. The patients in the no-ischemia group did not develop significant ischemia. Continuous variables were reported as medians with interquartile ranges and compared using Mann-Whitney U tests. Differences in categorical variables were assessed using χ 2 testing (Fisher's Exact). Statistical significance was assumed at P < .05. Results Twenty-one patients (age, 2-22 years) were cannulated via the CFA for VA ECMO. Significant ischemia requiring intervention (ischemia group) occurred in 11 (52%) of 21. In comparing the 2 groups (ischemia vs no ischemia), no clinical variables predicted the development of ischemia ( Table 1). In the ischemia group, 9 (81%) of 11 had a distal perfusion catheter (DPC) placed. Complications of DPC placement included one case of compartment syndrome requiring a fasciotomy and one patient requiring interval toe amputation. Of the 2 patients in the ischemia group who did not have a DPC placed, 1 required a vascular reconstruction of an injured superficial femoral artery and 1 underwent a below-the-knee amputation. Mortality was lower in the ischemia group (27% vs 60%). Conclusions Limb ischemia remains a significant problem, as more than half of our patients developed it. The true incidence may not be known as a 60% mortality in the no-ischemia group could mask subsequent ischemia. Although children are at risk for developing limb ischemia/loss, no variable was predictive of the development of significant limb ischemia in our series. Because of the inability to predict who will develop limb ischemia, early routine placement of a DPC at the time of cannulation may be warranted. However, DPCs do not completely resolve issues around tissue loss and morbidity. Prevention of limb ischemia/loss because of CFA cannulation for VA ECMO continues to be a problem that could benefit from new strategies.

Reconstruction of the Common Femoral Vein and Artery after Resection of a Leiomyosarcoma of the CFV

An innovative reconstruction of the common femoral vein (CFV) concomitant to reconstruction of the femoral arteries in case of a vascular leiomyosarcoma of the CFV is presented here. Preserving venous outflow in the CFV could prevent a post-thrombotic syndrome. A venous reconstruction with a venous spiral graft in combination with a stent prevents postoperative occlusion. Both the venous and arterial grafts remain patent at 1 year of follow-up.

Superficial femoral artery autograft reconstruction in the treatment of popliteal artery aneurysm: Long-term outcome

This prospective, observational study evaluated the safety and efficacy of superficial femoral artery autograft reconstruction in the treatment of popliteal artery aneurysms in the absence of a suitable saphenous vein. From March 1997 to April 2007, data from patients with popliteal artery aneurysms treated by superficial femoral artery reconstruction were prospectively collected in two centers. The procedure was performed through a medial approach. The superficial femoral artery was harvested in the upper third of the thigh and used as the conduit for reconstruction, and the harvested segment was replaced by a polytetrafluoroethylene graft. The patients were observed for survival, limb salvage, and reconstruction patency. The results were calculated by the Kaplan-Meier method. During the 10-year study period, 37 popliteal artery aneurysms in 32 patients (all men; median age, 71 years) were treated by reconstruction using the superficial femoral artery. Indications for surgical treatment were symptomatic or complicated aneurysms in 11 (30%). Four (11%) of the 37 popliteal artery aneurysms were thrombosed, and 33 (89%) were patent. At surgery, 35% had a single vessel runoff. Because of acute ischemia, reconstruction was performed as an emergency procedure in three patients (8%). There were no perioperative deaths, early amputations, or early thrombosis. The mean follow-up period was 36 months (range, 7-103 months). Two grafts thrombosed during follow-up. At 3 years, the primary and secondary patency rates were 86% and 96%, and overall limb salvage was 100%. Follow-up duplex ultrasonography did not detect any aneurysmal dilatation of the autograft. Our experience shows that superficial femoral arterial reconstruction is a safe and useful treatment option in patients with popliteal artery aneurysms who lack suitable saphenous veins. This reconstruction seems to be a good alternative to prosthetic bypass crossing the knee joint, and our results suggest that this study should be continued.

Endovascular management of iliac artery occlusions: extending treatment to TransAtlantic Inter-Society Consensus class C and D patients

The preferential use of endovascular techniques to treat complex aortoiliac disease has increased in recent years. The purpose of this study was to review the outcomes and durability of recanalization, percutaneous transluminal angioplasty, and stenting for iliac occlusions based on the patient's TransAtlantic Inter-Society Consensus (TASC) stratification. Between 1998 and 2004, more than 628 patients with a clinical diagnosis of aortoiliac atherosclerotic disease underwent arteriography. The endovascular treatment of 89 consecutive patients (mean age, 66 years; 58% male) with symptomatic iliac occlusions (TASC-B, -C, and -D) was the basis for this study. Original angiographic imaging was evaluated for lesion grade and runoff. Electronic and hard copy medical records were reviewed for demographic data, clinical variables, and noninvasive vascular laboratory testing. Kaplan-Meier estimators were used to determine patency rates according to Society for Vascular Surgery criteria. Univariate and multivariate analyses were performed. P values of <.05 were considered significant. Recanalization and percutaneous transluminal angioplasty/stenting (total, 178 stents) of occluded iliac arteries was technically successful in 84 (91%) of 92 procedures. Patients in the TASC-C and -D groups often required multiple access sites (50%) and femoral artery endarterectomy/patch angioplasty for diffuse disease (24%). The mean ankle-brachial index increased from 0.45 to 0.83. Distal embolization led to major amputation and eventual death in one patient. Two other deaths occurred in the perioperative period secondary to cardiorespiratory causes. Three-year primary patency, secondary patency, and limb salvage rates were 76%, 90%, and 97%, respectively, and progression of infrainguinal disease led to late limb loss in two patients. Diabetes as a risk factor was significantly associated with decreased primary patency (57% vs 83%; P = .049). Critical ischemia at presentation was associated with decreased patency rates as well (P = .002), but TASC classification did not significantly alter patency rates. Complex long-segment and bilateral iliac occlusions can be safely treated via endovascular means with high rates of symptom resolution. Initial technical success, low morbidity, and mid-term durability are comparable to results with open reconstruction. A liberal posture to open femoral artery reconstruction extends the ability to treat diffuse TASC-C and -D lesions via endovascular means.
