Intraoperative Transit-Time Flow as a Predictor of Failure after Infrainguinal Revascularization with Heparin-Bonded Expanded Polytetrafluoroethylene Graft.

BACKGROUND: The heparin-bonded expanded polytetrafluoroethylene (He-ePTFE) conduit is an option for patients requiring infrainguinal revascularization (iIR), but the risk of failure may be unpredictable, especially in cases with poor run-off. Intraoperative transit-time flow (TTF) provides an automated and quantitative analysis of flow and may serve as an adjunct evaluation during surgical revascularization. The aim of this study was to assess TTF in patients undergoing iIR with He-PTFE at 3 referral hospitals and to establish a predictive flow threshold for graft occlusion. METHODS: A prospective registry initiated in 2020 enrolled patients undergoing iIR using He-PTFE for critical limb ischemia or severe claudication, and TTF measurement was analyzed. Preoperative assessments of anatomical and clinical characteristics were available for all patients. The HT353 Optima Meter (Transonic Systems Inc., Ithaca, NY, USA) was used in all procedures according to a standardized protocol. The institutional ethics committee approved the study. A predictive model using receiver operating characteristic curve analysis was utilized to establish the threshold of flow, and variables were compared. Anatomical and clinical evaluation were reported according to Rutherford grade, Global Limb Anatomic System and Wound, Ischemia, and foot Infection classification. The main outcome considered was the correlation between TTF and graft occlusion. Secondary outcomes included survival, other predictors of graft occlusion, freedom from major adverse cardiovascular events, and freedom from major amputation. RESULTS: Among 68 patients, 55.8% had Rutherford 5-6, 45.6% had Global Limb Anatomic System 3 and 73.5% had Wound, Ischemia, and foot Infection 3-4. Distal anastomosis was at tibial level in 23.5% and mean diameter of conduit was 6.4 mm. Basal and postoperative TTF were 27.8 ± 15.6 ml/min and 109.0 ± 53.0 ml/min, respectively. After a mean follow-up of 18 ± 13 months, 7 (10.9%) patients presented graft occlusion and 5 (7.8%) required major amputation. TTF threshold = 80 ml/min revealed a sensitivity and specificity of 81.8% (95% confidence interval 48.2-97.7) and 80.7% (95% confidence interval 68.1-90.0) respectively, and it was selected as cut-off for graft occlusion. Freedom from graft occlusion in patients with TTF >80 ml/min vs. TTF ≤80 ml/min at 6, 12, and 24 months was 95.7% (standard error (SE) = 0.030) vs. 65.5% (SE = 0.115), 95.7% (SE = 0.030) vs. 58.9% (SE = 0.120) and 90.9% (SE = 0.054) vs. 51.6% (SE = 0.126), P = 0.0003. No statistical difference in primary patency, secondary patency and limb salvage was observed. At multivariate analysis, distal anastomosis at tibial vessel (odds ratio 8.50) and TTF ≤80 ml/min (odds ratio 9.39) were independent predictors of graft occlusion. CONCLUSIONS: These results suggest that TTF may serve as a valuable tool in the management of iIR. A TTF measurement of ≤80 ml/min should be regarded as a predictor of graft occlusion, prompting consideration of additional intraoperative maneuvers to enhance arterial flow. Caution should be exercised in patients requiring direct tibial artery revascularization, as it represents a predictor of failure independent of TTF levels. Larger cohorts of patients and longer follow-up periods are necessary to confirm these findings.

Major vascular traumas to the neck, upper limbs, and chest: Clinical presentation, diagnostic approach, and management strategies.

Major vascular traumas to the neck, upper limbs, and chest may arise from penetrating and/or blunt mechanisms, resulting in a range of clinical scenarios. Lesions to the carotid arteries may also lead to neurologic complications, such as stroke. The increasing use of invasive arterial access for diagnostic and/or interventional purposes has increased the rate of iatrogenic injuries, which usually occur in older and hospitalized patients. Bleeding control and restoration of perfusion represent the two main goals of treatment for vascular traumatic lesions. Open surgery still represents the gold standard for most lesions, although endovascular approaches have increasingly emerged as feasible and effective options, particularly for management of subclavian and aortic injuries. In addition to advanced imaging (including ultrasound, contrast-enhanced cross-sectional imaging, and arteriography) and life support measures, multidisciplinary care is required, particularly in the setting of concomitant injuries to the bones, soft tissues, or other vital organs. Modern vascular surgeons should be familiar with the whole armamentarium of open and endovascular techniques needed to manage major vascular traumas safely and promptly.

Association Between the Lockdown for SARS-CoV-2 (COVID-19) and Reduced Surgical Site Infections after Vascular Exposure in the Groin at Two Italian Academic Hospitals.

BACKGROUND: The aim of this study was to evaluate whether the scrupulous hygiene rules and the restriction of contacts during the lockdown owing to the COVID-19 pandemic affected the rate and severity of surgical site infections (SSI) after vascular exposure in the groin at two Italian University Hospitals. METHODS: Starting from March 2020, strict hygiene measures for protection of health care workers (HCW) and patients from COVID-19 infection were implemented, and partly lifted in July 2020. The main exposure for analysis purposes was the period in which patients were operated. Accordingly, study subjects were divided into two groups for subsequent comparisons (preCOVID-19 era: March-June 2018-2019 versus COVID-19 era: March-June 2020). The primary endpoint was the occurrence of superficial and/or deep SSI within 30 days after surgery. The Centers for Disease Control and Prevention definitions were used to classify superficial and deep SSI. RESULTS: A total of 194 consecutive patients who underwent vascular exposure in the groin were retrospectively analyzed. Of those, 60 underwent surgery from April 1, 2018 to June 30 of the same year; 83 from April 1, 2019 to June 30 of the same year; and 51 from April 1, 2020 to June 30 of the same year. The mean age of the study cohort was 75 years and 140 (72%) were males. Patients who were operated in the COVID-19 era were less likely to develop SSI (10% vs. 28%; P = 0.008), including both deep SSI (4% vs. 13%; P = 0.04) and superficial SSI (6% vs. 15%; P = 0.05). After multivariate adjustments, being operated in the COVID-19 era was found to be a negative predictor for development of an SSI (odds ratio [OR] = 0.31; 95% confidence interval [CI] = 0.09-0.76; P < 0.001) or deep SSI (OR = 0.21; 95% CI = 0.03-0.98; P < 0.001). Operative time was also found as independent predictor for the development of deep SSI (OR = 1.21; 95%CI = 1.21-1.52; P = 0.02). Using binary logistic regression, there were no independent predictors of superficial SSI that could be identified. CONCLUSIONS: Vascular exposure in the groin carries a non-negligible risk of SSI. In this study, we provided important insights that are simple and easily viable precautions (such as the universal use of surgical masks both for patients and health care professionals during wound care, the widespread diffusion of hand sanitizers, and the reduction of the number of visitors in the surgical wards) could be promising and safe tools for SSI risk reduction.

Association Between Psoas Muscle Sarcopenia and Long-Term Survival Following Elective Endovascular Aortic Repair.

INTRODUCTION: The aims of this study were as follows: i) to identify the prevalence of sarcopenia in patients undergoing elective endovascular aortic repair (EVAR) for intact abdominal aortic aneurysm; ii) to assess its association with perioperative morbidity and long-term survival; and iii) to estimate its diagnostic accuracy for prediction of 5-year mortality following the intervention. METHODS: We performed a retrospective review of all patients who underwent elective EVAR from January 1, 2010 through December 31, 2019. The lean psoas muscle area (LPMA; cm2 × HU) was calculated on computed tomography angiography by multiplying psoas muscle area and psoas muscle density. The main exposure variable for this study was the presence of preoperative sarcopenia (LPMA value < 350), and the study cohort was divided in two groups for all subsequent analyses. The primary endpoint was all-cause mortality. RESULTS: The study cohort eventually comprised 338 patients who underwent elective EVAR for intact abdominal aortic aneurysm. In the overall population, 154 patients (45.5%) were classified as sarcopenic. At baseline, patients with sarcopenia were older (mean age: 78 ± 5 versus 75 ± 7 y, P < 0.001) and had lower proportion of males (73.5% versus 93.5%, P < 0.001). At 5 y, the estimated survival rates were 52% versus 74% in sarcopenic and nonsarcopenic patients, respectively (P < 0.001). Using multivariate Cox proportional hazard regression, an independent association was identified between sarcopenia and all-cause mortality in the whole cohort (hazard ratio: 2.63, 95% confidence interval: 1.43-3.36, P = 0.009). CONCLUSIONS: Sarcopenia, defined as LPMA <350 as measured on preoperative computed tomography angiography, can be highly prevalent in patients undergoing elective EVAR. Although the intervention remains safe in the short term, presence of sarcopenia was significantly associated to lower long-term survival irrespective of patients' age or gender.

Peri-Operative Management of Patients Undergoing Fenestrated-Branched Endovascular Repair for Juxtarenal, Pararenal and Thoracoabdominal Aortic Aneurysms: Preventing, Recognizing and Treating Complications to Improve Clinical Outcomes.

The advent and refinement of complex endovascular techniques in the last two decades has revolutionized the field of vascular surgery. This has allowed an effective minimally invasive treatment of extensive disease involving the pararenal and the thoracoabdominal aorta. Fenestrated-branched EVAR (F/BEVAR) now represents a feasible technical solution to address these complex diseases, moving the proximal sealing zone above the renal-visceral vessels take-off and preserving their patency. The aim of this paper was to provide a narrative review on the peri-operative management of patients undergoing F/BEVAR procedures for juxtarenal abdominal aortic aneurysm (JAAA), pararenal abdominal aortic aneurysm (PRAA) or thoracoabdominal aortic aneurism (TAAA). It will focus on how to prevent, diagnose, and manage the complications ensuing from these complex interventions, in order to improve clinical outcomes. Indeed, F/BEVAR remains a technically, physiologically, and mentally demanding procedure. Intraoperative adverse events often require prolonged or additional procedures and complications may significantly impact a patient's quality of life, health status, and overall cost of care. The presence of standardized preoperative, perioperative, and postoperative pathways of care, together with surgeons and teams with significant experience in aortic surgery, should be considered as crucial points to improve clinical outcomes. Aggressive prevention, prompt diagnosis and timely rescue of any major adverse events following the procedure remain paramount clinical needs.

Secondary Relining With Focal Flaring of Novel-Generation Balloon-Expandable Covered Stents for Endovascular Treatment of Significant Diameter Mismatch in the Aorto-Iliac Territory.

OBJECTIVES: The aim of this study was to report on the safety and feasibility of secondary relining with focal flaring of novel-generation balloon-expandable covered stents for endovascular treatment of significant diameter mismatch in the aorto-iliac territory. Significant diameter mismatch was defined as >20% difference in the nominal diameter between the intended proximal and distal landing zones. METHODS: Patient A was an 84-year-old man with prior abdominal aortic aneurysm open repair with a straight 20 mm Dacron tube. He presented with a right common iliac artery aneurysm (Ø88 mm) with contained rupture. The Gore Viabahn endoprosthesis (9 mm × 5 cm) was inserted proximally about 15 mm above the occluded ostium of the internal iliac artery. Subsequently, the BeGraft Aortic® (16 mm × 48 mm) was inserted proximally up to the common iliac artery origin; its proximal portion was flared to 22 mm. Patient B was a 77-year-old man with prior endovascular abdominal aortic aneurysm repair with a Medtronic Endurant stent-graft. He presented with occlusion of the right limb of the aortic endoprosthesis and thrombosis that extended down to the level of the superficial femoral artery. After mechanical thrombectomy, two Gore Viabahn endoprosthesis (first one, 8 mm × 10 cm; second one, 10 mm × 15 cm) were inserted into the right iliac limb. Subsequently, the BeGraft Aortic® (12mm × 39mm) was inserted proximally up to the gate of the aortic stent-graft; its proximal portion was flared to 16 mm. RESULTS: Technical success and clinical success were achieved in both patients. Imaging follow-up (6 months for Patient A, 12 months for Patient B) showed correct placement of all stent-grafts without any graft-related adverse event. The patients remained free from new reinterventions or recurrent symptoms. Patient A died 8 months after the index procedure from acute respiratory failure after community acquired pneumonia. CONCLUSION: Secondary relining with focal flaring of novel-generation balloon-expandable covered stents for endovascular treatment of significant diameter mismatch in the aorto-iliac territory is safe and feasible. Although mid-term results seem to be effective, longer follow-up is warranted to establish durability of the technique.

Novel Application of Custom-Made Stent Grafts with Inner Branches for Secondary Treatment After Stent Graft Migration of Previous Infrarenal Endovascular Aortic Repair.

PURPOSE: We present a novel application of custom-made stent grafts (CMSGs) with inner branches to incorporate target vessels (TVs) as an alternative to fenestrations or directional branches for secondary treatment after stent graft migration of previous infrarenal endovascular aortic repair (EVAR). CASE REPORT: Two consecutive patients with stent graft migration of previous EVAR were electively treated at our institution from January 1, 2018 through December 31, 2018. Stent graft migration was defined as radiologic evidence of stent graft displacement >10 mm. In both cases, a proximal type I endoleak was noted, and the residual infrarenal aorta above the previous endograft was unsuitable as the proximal landing zone for a nonfenestrated cuff. Repair was planned by means of a CMSG with 4 inner branches. The procedures were conducted in two-stage fashion to minimize the risk of spinal cord ischemia. The procedures were technically successful with a total of 8 TVs stented. Both patients did not suffer from any early (i.e., up to 30 days) major adverse events, and no access-site complications were noted. At one-year follow-up, computed tomography angiography showed regular placement of the CMSGs, widely patent TVs, absence of any type I or III endoleak, and stable sac size. No late reinterventions were recorded. CONCLUSIONS: Secondary treatment of stent graft migration after previous EVAR is safe and feasible using CSMGs with 4 inner branches. This technique is effective as showed by stable sac size and 100% freedom from TVI at mid-term imaging follow-up. Larger cohorts and longer follow-up are needed to confirm the preliminary results.

Secondary Endovascular Repair of Recurring Lesions and Perioperative Complications after Open Aortic Repair: The Complementary Role of Different Technical Solutions.

BACKGROUND: The aim of our article was to describe the complementary role of different technical solutions for secondary endovascular repair of recurring lesions and perioperative complications after open aortic repair (OAR). METHODS: We describe our clinical experience of secondary endovascular repair after OAR. We included in the analysis all consecutive patients who presented recurring lesions and perioperative complications after OAR and underwent secondary endovascular repair between January 1, 2015 and June 31, 2018. Both elective and nonelective cases were captured. Early end points were technical success, 30-day mortality, 30-day major adverse events, and 30-day vascular access complications. Late end points were survival and freedom from secondary interventions. RESULTS: Three different techniques were used in 6 patients: 2 cases of fenestrated-branched endovascular aortic repair (F-BEVAR), 2 cases of parallel-graft EVAR (pg-EVAR), and 2 cases of off-label use of standard devices. Technical success was 100%. One patient died within 30 days from acute pulmonary embolism. One patient developed acute kidney injury not requiring renal replacement therapy, whereas the remaining 4 patients were free from 30-day major adverse events. The cumulative rate of 30-day vascular access complications was 0%. All the 5 patients who survived the index hospitalization had ≥12 months of clinical and imaging follow-up. At the longest individual follow-up, they all were alive and free from secondary interventions. Computed tomography angiography showed in all cases sustained clinical success. CONCLUSIONS: Secondary endovascular repair of recurring lesions and perioperative complications after OAR is safe and feasible and offers a minimally invasive effective treatment option when a redo surgical operation would be associated with a considerable risk to the patient. Different solutions are available (including F-BEVAR, pg-EVAR, and off-label use of standard devices) and are complementary rather than competitive. Careful preoperative assessment and familiarity with advanced techniques are essential to achieve satisfactory outcomes.

Custom-Made Unibody Conical Endografts for Elective Endovascular Repair of Saccular Infrarenal Abdominal Aortic Aneurysms with Narrow Aortic Bifurcations-Novel Implementation of the Aortoaortic Concept.

The aortoaortic concept for endovascular repair (EVAR) of infrarenal abdominal aortic aneurysms (AAAs) is nearly forgotten but may constitute a valuable option for focal pathologies. Herein, we describe our experience using custom-made (CM) unibody conical endografts for saccular AAAs with narrow (≤20 mm wide) aortic bifurcation (AB) in three patients. Given the narrow AB, the option for a bifurcated stent graft was reputed not optimal. Therefore, we decided to further suggest the construction of a CM unibody conical stent graft with respect to unique anatomical characteristics of the patients. Technical success rate was 100%, and computed tomography angiography at first-month follow-up showed complete sealing proximally and distally with excellent conformability of the endografts in all the cases. All the patients were free from any-type endoleak (EL) and had no evidence of any endograft-related complication (i.e., fracture, thrombosis, or migration) or required any reintervention at their longest follow-up. We conclude that in the proper anatomic setting, the use of CM unibody conical endografts for elective EVAR of saccular AAAs with narrow AB is technically feasible with excellent short-term safety regarding ELs or migration.

Successful Off-Label Use of an Iliac Branch Device to Rescue an Occluded Aortofemoral Bypass Graft.

PURPOSE: To report an alternative approach for rescue of an occluded aortofemoral bypass using the Gore Excluder Iliac Branch Endoprosthesis (IBE). CASE REPORT: A 52-year-old man presented with acute right limb ischemia because of displaced and occluded iliac stents and was treated with aortofemoral bypass. On the third postoperative day, there was early bypass failure due to distal embolization from aortic thrombus. After fluoroscopy-guided balloon thrombectomy of the bypass, an endovascular bailout strategy was used. The Gore Excluder IBE was deployed below the renal arteries (with the external iliac limb opening in the surgical prosthesis and the gate opening within the aortic lumen). After antegrade catheterization of the gate, a Gore Viabahn endoprosthesis was inserted as the bridging endograft and deployed so that it landed just above the preimplanted aortoiliac kissing stents without overlapping them. Completion angiography showed technical success without complications; results were sustained at 1-year follow-up. CONCLUSION: The Gore Excluder IBE may represent a versatile solution for the rescue of complex cases when open surgery would be associated with a considerable risk. This off-label application of a well-recognized endovascular device is safe and feasible and may prove useful as a valuable alternative in properly selected patients.

Hybrid Treatment of a True Right Subclavian Artery Aneurysm Involving the Vertebral Artery using a Covered Stent.

Subclavian artery aneurysms (SAAs) are rare but potentially life- and limb-threatening. We present the case of a 69-year-old man with a true right SAA; the vertebral artery branched off the aneurysm and was the dominant one. A hybrid (combined open surgical and endovascular) repair was performed; the vertebral artery was anastomosed end to side to the common carotid artery through a right supraclavicular incision, then using a percutaneous high brachial artery access, a covered stent was deployed to exclude the SSA. The procedure was technically successful, and computed tomography angiography at 24 months showed regular placement of the endograft with blood flow within it and absence of any endograft-related complication (i.e., stent fracture/thrombosis/displacement or any-type detectable endoleak). This hybrid treatment is safe and feasible with good midterm results and may represent a valuable, less invasive alternative to conventional open surgical approaches.

Urgent Use of Gore Excluder Iliac Branch Endoprosthesis with Left Transaxillary Approach for Preservation of the Residual Hypogastric Artery: A Case Series.

BACKGROUND: Preservation of the residual hypogastric artery (HGA) in patients with previous endovascular aortic aneurysm repair (EVAR) may require complex operative strategies. We report an alternative technique to preserve the residual HGA with the Gore Excluder Iliac Branch endoprosthesis (IBE) in urgent situations. METHODS: We report the case of 2 high-risk patients (unfit for open surgery), with previous EVAR and exclusion of 1 HGA, treated in emergency setting. Both patients met the anatomical requirements for Gore IBE use. Due to lack of the native aortic bifurcation, we used a transaxillary approach to deploy a covered stent (Gore Viabahn) in the target HGA. RESULTS: Technical success was 100%. Computed tomography angiography at 30 days, 6 months, and 1 year showed regular placement of all endografts and patency of all residual HGAs without evidence of any endograft-related complication (i.e., stent fracture, stent thrombosis or stent displacement). There was not any detectable type 1, 2, or 3 endoleak at longest follow-up. CONCLUSIONS: Our case series shows the technical feasibility and the good results of this approach, which may prove useful when the native aortoiliac carrefour is no longer available. The procedure seems to be safe and effective, with optimal primary patency of the stent grafts, freedom from type 1, 2, and 3 endoleaks, and absence of pelvic ischemic complications.

Endovascular Exclusion of Hypogastric Aneurysms Using Distal Branches of the Internal Iliac Artery as Landing Zone: A Case Series.

BACKGROUND: The purpose of the study was to report an alternative endovascular technique to exclude aneurysms of the internal iliac artery in the setting of abdominal aortic aneurysm (AAA) disease using the anterior division of the hypogastric artery (HGA) or the superior gluteal artery (SGA) as distal landing zone for the stent graft. METHODS: Three patients with HGA aneurysms in the setting of AAA that were excluded with placement of a self-expandable covered stent. In 2 patients, the AAA had been already treated with resulting exclusion of 1 HGA, while in the remaining we treated the hypogastric aneurysm before the AAA. We used as distal landing zone the anterior division of the HGA or the SGA. We adopted a "stent-within-a-stent" or "telescope" technique to manage diameter discrepancy between proximal and distal landing zone. RESULTS: Computed tomography angiography (CTA) at 6 and 12 months showed regular placement and patency of the stent grafts placed and absence of detectable endoleaks (EL). None of the patients developed pelvic ischemic complication at longest follow-up. CONCLUSIONS: The procedure seems to be safe and effective, with optimal primary patency of the stent grafts, freedom from type 1 and 2 endoleaks, and absence of pelvic ischemic complications in the short-term and mid-term.

Endovascular Management of Infected Femoral Artery Pseudoaneurysms in High-Risk Patients: A Case Series.

We report our experience with the urgent treatment of two high-risk patients with infected femoral artery pseudoaneurysms (IFAPs) with the placement of a self-expandable covered stent (SECS). In both cases, there was no perioperative mortality and the aneurysm exclusion was successful without early or late stent thrombosis/stent fracture nor acute or chronic limb ischemia or limb loss. There was no recurrence of local or systemic infection during the follow-up period. Endovascular therapy represents a feasible treatment option for IFAPs in those patients for whom the risk of open surgical repair would be prohibitive, especially under urgent circumstances.

Management of an Iatrogenic Pseudoaneurysm of the Superior Gluteal Artery by Percutaneous Ultrasound-Guided Thrombin Injection: A Case Report.

We report the unusual case of a pseudoaneurysm of the superior gluteal artery (SGA) as a complication of a bone marrow biopsy. A 75-year-old man presented with pain and swelling of the left buttock 1 month after a bone marrow biopsy of the left iliac crest. The patient was treated by percutaneous ultrasound-guided thrombin injection (UGTI). The procedure was successful without any complication and the patient was discharged at home the same day. Follow-up at 3 months after the procedure confirmed the complete thrombosis of the pseudoaneurysm sac. At the best of our knowledge, UGTI of a pseudoaneurysm of the SGA has never been reported since now in the English literature.

Early and mid-term results of totally laparoscopic surgery for aortoiliac disease: lessons learned.

The present article is the first in the literature reporting short- and medium-term results using a totally laparoscopic technique for aortoiliac disease.Forty-nine patients, 6 having an associated small aneurysm, were scheduled for totally laparoscopic surgery (TLS) for aortoiliac occlusive disease and 2 for treatment of aortic aneurysmal disease (AAA). Patients' characteristics, intraoperative, postoperative data and mid-term data were recorded.TLS was successfully completed in 45 patients. Of those patients, 41 received an aortobifemoral bypass; three, an iliofemoral bypass; and one, an aortoaortic bypass. Five patients were converted from TLS to video-assisted laparoscopic surgery using incisions varying in size from 7 cm to 11 cm. One patient underwent conversion to standard open surgery. One death occurred unrelated to the technique. Major perioperative complications related to the technique were few and presented in the early phase of the study: One intraoperative embolization to the lower limbs that needed embolectomy, and one acute aortic false aneurysm. Midterm results were favorable, demonstrating two limb graft thromboses. Hernias at trocar sites occurred in only 3.9%. The patients benefited from this procedure, which is considered definitive like its standard open counterpart. The conversion rate is lower than that reported for acute cholecystitis. Selection of patients has been less stringent during the second half of the study in term of inclusion of patients with AAA and of more TASC IV patients. Surgeons willing to learn this technique should attend dedicated courses. In the future, as this surgical innovation matures, controlled randomized studies should be initiated.

Endovascular treatment of external iliac artery injuries after hip arthroplasty.

PURPOSE: To report endovascular repair of injuries to the external iliac artery during hip surgery. CASE REPORTS: Two elderly women with histories of chronically infected hip prostheses were found to have iatrogenic leaking pseudoaneurysms of the external iliac artery due to hip surgery trauma in the past. Both were treated successfully with a Jostent Peripheral Stent-Graft. The first patient died 17 months after treatment, and the second was well, with an excluded false aneurysm, at the 6-month follow-up. CONCLUSIONS: Stent-graft repair may be an appropriate and effective treatment for some traumatic arterial lesions.
