RESUMEN
Peripheral artery disease (PAD) is estimated to affect approximately 8.5 million individuals in the US above the age of 40, and is associated with significant morbidity, mortality, and impairment. Despite the significant adverse limb and cardiovascular (CV) outcomes seen in patients with PAD, there is typically less attention paid to risk factor modification relative to other atherosclerotic diseases such as coronary artery disease (CAD) or stroke. In the current literature, statins have been shown to reduce mortality, major adverse CV events, major adverse limb events, and improve symptomatic outcomes in patients with PAD. In addition, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are emerging as an additional lipid-lowering therapy for patients with PAD. However, despite current guideline recommendations based on growing evidence, patients with PAD are consistently undertreated with lipid-lowering therapies. We provide an extensive literature review and evidence-based recommendations for the use of statins and PCSK9 inhibitors in patients with PAD.

BACKGROUND: Current recommendations suggest lifetime follow-up for endovascular aortic aneurysm repair (EVAR) patients to avoid consequences associated with endoleak and aneurysm enlargement. Follow-up compliance has been reported between 43% and 92%, with most single-center studies citing successful follow-up surveillance at less than 60%. We investigated follow-up completeness with a defined surveillance program and subsequent secondary intervention prevalence from a single center. METHODS: Our surveillance program notified patients of the need for follow-up imaging and surgeon review. Data were obtained from retrospective review of a prospective database, including operative and follow-up details, follow-up imaging completeness, endoleak incidence, and secondary intervention prevalence. RESULTS: Five hundred seventeen patients received elective EVAR from 2005 to 2015. Surveillance was achieved in 425 (82.3%). Mean number of follow-up studies was 4.2 ± 2.9 and median time to first follow-up was 36 days. Four hundred forty-eight patients (86.7%) had freedom from intervention. Sixty-nine unique patients (13.3%) had 107 secondary interventions. Median time to first secondary intervention in 69 patients was 476 days. Mean number of imaging studies for secondary intervention patients was 6.1 ± 3.9, compared with mean 3.4 ± 2.3 for patients without (P < 0.001). Overall mortality was 24.6% (n = 127), including 32 deaths of unknown cause (6.2% overall) and 95 of non-EVAR-related causes (18.3%). No aneurysm-related deaths were reported. CONCLUSIONS: Regular post-EVAR surveillance through a dedicated program resulted in a high rate of follow-up compliance, 13.3% rate of secondary intervention, and low aneurysm-related mortality. Careful lifetime surveillance remains important in long-term care following elective EVAR.

Takayasu arteritis is a rare, chronic large vessel vasculitis of unknown etiology which predominantly affects women younger than 40 years of age. Symptoms are highly variable based on the location and extent of the stenosis, arterial occlusion, aneurysm, and thrombosis. Diagnosis is based on clinical presentation, relevant laboratory work-up, and imaging findings of wall thickening and stenosis of medium and large vessels. Management includes glucocorticoid therapy, frequently paired with adjunctive immunosuppressants, and sometimes surgical intervention in severe cases. Here, we present a unique case of Takayasu arteritis with critical distal aortic stenosis with very severe wall thickening involving the bilateral common iliac artery and leading to left iliac artery thrombosis. Based on our literature review, our article represents a very rare presentation of Takayasu arteritis with severe iliac artery thrombosis.

BACKGROUND: Hyperbaric oxygen (HBO) is used as an adjunctive therapy for a variety of indications. However, there is a lack of high-quality research evaluating HBO treatment outcomes for different indications available in the current literature. METHODS: We retrospectively reviewed all patients who underwent HBO therapy at a single hyperbaric center from January 2010 to December 2013 using predetermined criteria to analyze successful, improved, or failed treatment outcomes for the following indications: chronic refractory osteomyelitis, diabetic foot ulcer, failed flap or skin graft, osteoradionecrosis, soft tissue radiation necrosis, and multiple coexisting indications. RESULTS: Among the included 181 patients treated with adjunctive HBO at our center, 81.8% had either successful or improved treatment outcomes. A successful or improved outcome was observed in 82.6% of patients treated for chronic refractory osteomyelitis (n = 23), 74.1% for diabetic foot ulcer (n = 27), 75.7% for failed flap or skin graft (n = 33), 95.7% for osteoradionecrosis (n = 23), 88.1% for soft tissue radiation necrosis (n = 42), and 72.4% for multiple coexisting indications (n = 29). Among 4 patients treated for other indications, 100% of the cases were either successful or improved. CONCLUSIONS: This study has provided a comprehensive outcome survey of using HBO for the previously mentioned indications at our center. It supplements the literature with more evidence to support the consideration of HBO in different indications.

BACKGROUND: Chronic venous ulcer (CVU) is common and is responsible for significant health care expenditures worldwide. Compression is the mainstay of treatment, but long-term compliance with this therapy is often inconsistent, particularly in the elderly and infirm. Surgical ablation of axial and perforator reflux has been used as an adjunct to compression to reduce recurrence rates and assist healing. These surgical techniques are being replaced by minimally invasive procedures, such as thermal ablation and foam sclerotherapy, in the treatment of uncomplicated venous disease. The role for these techniques in the treatment of CVU is just beginning to be defined. METHODS: Eighty-six patients with CVU with 95 active ulcers (Clinical, Etiology, Anatomy, Physiology-CEAP clinical class 6) presenting to a multispecialty wound clinic were retrospectively reviewed and analyzed by leg. All patients underwent duplex scanning for venous insufficiency. Ulcer dimensions at each visit were recorded and used to calculate healing rates. Presence or absence of ulcer recurrence at 1-year follow-up was recorded. Ulcers treated with compression alone ("compression group") were compared with those treated with compression and minimally invasive interventions, such as thermal ablation of superficial axial reflux and ultrasound-guided foam sclerotherapy (UGFS) of incompetent perforating veins and varicosities ("intervention group"). RESULTS: The average age in the intervention and compression groups was 67 and 71 years, respectively (P = not significant [NS]). Body mass index was 32.4 ± 9.5 and 33.6 ± 11.8 kg/m(2), in the compression and intervention groups, respectively (P = not significant [NS]). Ulcers were recurrent in 42% of the intervention group and 26% of the compression group (P = NS). In the intervention group, 33% had radiofrequency ablation of axial reflux, 31% had UGFS of perforators, and 29% had both treatments. The only complication of intervention was a single case of cellulitis requiring hospitalization. Compared with the compression group, the ulcers in the intervention group healed faster (9.7% vs. 4.2% per week; P = 0.001) and showed fewer recurrences at 1-year follow-up (27.1% vs. 48.9 %; P < 0.015). Multivariate analysis showed use of intervention was the strongest determinant of healing with a coefficient of variation of 7.432, SE 2.406, P = 0.003. Analysis of just the intervention group before and after intervention using matched pairs showed acceleration of healing after intervention from ranging from a median of 1.2% (interquartile range [IQR], 14.3) to 9.7% (IQR, 11.3) per week (P ≤ 0.001). CONCLUSIONS: Minimally invasive ablation of superficial axial and perforator vein reflux in patients with active CVU is safe and leads to faster healing and decreased ulcer recurrence when combined with compression alone in the treatment of CVU.

Traditional methods for revascularization of an occluded aortoiliac system have necessitated either in-line aortic reconstruction through an aortobifemoral bypass or extra-anatomic bypass. However, both these approaches require artificial material to be placed in the groin. The consequence of groin infection can be devastating leading to high rates of both limb loss and mortality. One of the most feared patient populations presenting with groin complications is that of the intravenous drug abuser. We present the case of a patient with a long history of intravenous drug abuse with severe aortoiliac disease. Instead of resorting to a more traditional open surgical approach necessitating artificial reconstruction in the groin, we chose to proceed with a hybrid open and endovascular procedure through a direct open surgical access to the aortic bifurcation. This allowed for revascularization without the placement of artificial material in the groin.

An aneurysm of the inferior mesenteric artery is a rarely described clinical presentation. We have presented the case of a ruptured aneurysm originating from a branch of the inferior mesenteric artery that might represent an aneurysm of the left colic artery or the arc of Riolan. Aneurysms of this anatomic location can develop secondary to mesenteric occlusive disease, alterations in mesenteric blood flow from previous operations, or connective tissue disease. In the present case, a patient with a ruptured inferior mesenteric artery branch aneurysm had presented with intra-abdominal hemorrhage, which was successfully treated with endovascular embolization.
RESUMEN
Postoperative immobility can exacerbate the physical and psychologic effects of limb loss. This case report presents a 37-year-old mother of two children who required a transtibial amputation. She received an early ambulation device called the bent knee temporary prosthesis (BKTP), which aids in early postoperative ambulation. Several early ambulation devices have been utilized in the past but have not found widespread favor. Although there is a paucity of research on this topic, available data suggest patient tolerance and benefit of early ambulation. A customizable, temporary below knee prosthesis such as the BKTP is valuable to study the safety and efficacy of early postoperative ambulation for improving outcomes for transtibial amputees.

BACKGROUND: Aortitis is a rare condition with inflammatory or infectious etiology that can be difficult to diagnose due to the highly variable clinical presentation and nonspecific symptoms. However, current literature on the diagnosis, management, and prognosis of aortitis is extremely scarce. METHODS: We retrospectively reviewed all patients' charts who were diagnosed with giant cell arteritis, Takayasu arteritis, or noninfectious aortitis presenting at a single center between January 1, 2009, and April 17, 2015. Data collected included demographics, medical history, comorbidities, laboratory and imaging data, management, and outcome. RESULTS: Among the included 15 patients presenting with aortitis at our center, 53% were diagnosed with Takayasu arteritis, 33% with idiopathic inflammatory aortitis, and 13% with giant cell arteritis. All patients received steroid treatment, 67% received adjunctive immunosuppressants or immunomodulators, and 33% underwent interventional procedures. Based on clinical presentation and laboratory and imaging findings at the last follow-up visit for each patient, 67% showed improvement, 27% had no change in disease activity, and 7% had a progression of the disease. CONCLUSIONS: Takayasu arteritis was found to be more common than idiopathic inflammatory aortitis and giant cell arteritis among our 15 cases diagnosed with aortitis. All patients received medical therapy and 33% received interventional procedures, leading to 67% improvement of disease activity or related complications. This article also offers a comprehensive review of the diagnosis, management, and outcome of aortitis, supplementing the very limited literature on this disease.

Popliteal artery entrapment syndrome (PAES) is an uncommon condition resulting from an abnormal anatomic relationship between the popliteal artery and the surrounding musculature. The compression created by this variance in anatomy can lead to ischemia and vascular claudication. The diagnosis of PAES requires a thorough patient history and physical exam, a high index of suspicion, and dedicated imaging techniques. Several treatment options are available, including surgical intervention, thrombolysis, or a combination of these depending on the clinical indication. We present a case of PAES in a 34-year-old man who presented with typical symptoms illustrative of the complicated decision making related to this disorder.
RESUMEN
OBJECTIVE: Upper extremity ischemia (UEI) is an uncommon condition that can lead to permanent disability. There is a limited understanding of the etiology, management, and outcomes of the disease. METHODS: We retrospectively reviewed the charts of all patients who were diagnosed with "embolism and/or thrombosis of arteries of upper extremity" at our institution from January 2005 to December 2013. RESULTS: Patients diagnosed with embolisms were older (P < .001), more likely to undergo thromboembolectomy (P < .001), had higher rates of hypertension (P = .001), and had longer lengths of hospital stay (P = .002). There were no significant differences in complications or mortality at 30 days and up to 1 year. CONCLUSION: At our center, embolism was found to be the most common etiology for UEI followed by thrombosis and stenosis. Patients presented with embolism were older, were more likely to undergo thromboembolectomy, and had higher rates of hypertension and longer hospital stays.

HYPOTHESIS: Percutaneous angioplasty would provide a durable alternative to surgical revision in the treatment of infrainguinal vein graft stenosis. DESIGN: Outcome analysis of the results of percutaneous angioplasty of infrainguinal vein graft stenosis. SETTING: Academic vascular surgical practice in a university-affiliated community hospital. PARTICIPANTS: All patients undergoing percutaneous intervention for infrainguinal vein graft stenosis from January 1, 1995, to May 31, 2002, were enrolled in the study. INTERVENTIONS: Lower extremity arterial reconstruction was performed by one of us. Proximal and distal sites of graft placement were identified, as well as the conduit used. Percutaneous angioplasty was performed on grafts by 1 of 4 interventional radiologists. Criteria for intervention and the anatomic location of intervention were noted. Morbidity from percutaneous intervention was also determined. MAIN OUTCOME MEASURES: Success and durability of percutaneous angioplasty were determined by clinical follow-up, duplex surveillance, and arteriography. Failure was defined as duplex ultrasonographic or arteriographic documentation of stenosis of 75% or greater. Kaplan-Meier life table analysis was applied to all grafts in the study. RESULTS: Ninety-four patients with 101 grafts were included in the study. Nearly 35% of angioplasties had failed at 6 months, 53.6% had failed at 12 months, 60.6% had failed at 24 months, and 75.1% had failed at 36 months. Comorbid disease, use of anticoagulant medications, criteria for intervention, or anatomic location of percutaneous intervention did not affect patency. Eight angioplasties (7.9%) were associated with significant complications. CONCLUSIONS: Percutaneous angioplasty does not provide a durable solution to the problem of infrainguinal vein graft stenosis. Because of the high rate of complications, its routine use cannot be advocated.

New developments in the management of both acute and chronic iliac vein occlusive disease offer exciting options for the treatment of this often debilitating condition. Percutaneous clot removal using thrombolysis, mechanical thrombectomy, or a combination of the two is fast becoming the treatment of choice for patients presenting with acute iliofemoral deep vein thrombosis. Recanalization of chronic iliac vein occlusions with balloon angioplasty and stenting relieves symptoms of extremity swelling and pain in the majority of treated patients. Existing data provide convincing proof of the efficacy of endovascular recanalization procedures, and upcoming prospective, controlled trials will further clarify the role of these techniques in the therapeutic armamentarium.

The purpose of this study was to determine whether duplex ultrasonography can be used as an effective modality for the preoperative evaluation of lower-extremity arterial occlusive disease. The records of all patients undergoing both color flow duplex scanning and contrast arteriography of the lower extremities during a 13-month period were reviewed. Comparisons between the two modalities were made at the femoral, popliteal, and tibial artery levels. Sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy were calculated for duplex scanning using angiography as the gold standard. Three hundred fifteen arterial segments were evaluated. Color flow imaging overestimated the degree of stenosis in seven vessels and underestimated the degree of stenosis in four vessels. Overall duplex ultrasonography accurately determined lower-extremity arterial anatomy as defined by contrast arteriography with a sensitivity of 96.9 per cent, a specificity of 96.2 per cent, a positive predictive value of 94.6 per cent, a negative predictive value of 97.8 per cent, and an overall accuracy of 96 per cent. The accuracy of duplex ultrasonography must be determined in each individual vascular laboratory. Once this is satisfactorily accomplished color flow scanning may be used as the single imaging modality for lower-extremity arterial occlusive disease in selected patients deemed to be at high risk for contrast angiography.

Arterial embolism is frequently the product of a cardiac source. Arterial-arterial embolization and paradoxical embolization also occur. Failure to identify the point of origin may subject the patient to an important incidence of preventable events. Conventional echocardiography is insensitive in identifying a cardiac origin of emboli and is of little use in identifying sources of arterial-arterial emboli. Aortography is invasive and not as sensitive in detecting mobile aortic thrombus, which is a recently reported embolic source. Herein we describe seven cases in which transesophageal echocardiography was uniquely valuable in identifying the source or mechanism of arterial embolization. We performed chart reviews of patients with arterial emboli definitively diagnosed after utilizing transesophageal echocardiography. Four females and three males with a mean age of 68 years were included in the study. Peripheral embolization occurred in four patients, visceral embolization occurred in one patient, and two patients experienced cerebrovascular events. Six patients had transthoracic echocardiography and six patients had aortography. None of these studies identified the source of embolization. All patients were diagnosed with transesophageal echocardiography. Mobile aortic thrombus was the primary embolic source in three patients, paradoxical embolization occurred in two patients, and two patients had a combination of findings including one patient with atrial thrombus. Two patients received operative repair of the aorta and five underwent nonoperative management. There was one mortality in the operative group. The source of arterial emboli remains obscure in some patients. Transesophageal ultrasound can be valuable in identifying the source or mechanism of embolization even when angiography and conventional echocardiography are negative.

We report our staged multimodal treatment of a female infant with a very large complex venolymphatic malformation of the axilla and chest wall. We successfully managed the patient's severely restricted arm mobility and consumptive coagulopathy with surgical debulking followed by medical therapy with the mammalian target of rapamycin inhibitor sirolimus. The diseased burden reduced in size throughout therapy, and hematologic parameters reached and maintained normal levels. Normal health and limb functionality were restored with no observed adverse side effects of medical therapy. This case presents a previously unreported and potentially promising method to treat severe vascular malformations.
RESUMEN
OBJECTIVES: Retrospective case-control study to determine the failure and endovenous heat-induced thrombosis (EHIT) rates of endovenous ablation (EVA) in patients with a history of superficial venous thrombosis (SVT). METHODS: Study and control groups each consisted of 73 patients with or without the history of SVT, who underwent EVA between June 2010 and July 2012. All patients were followed with venous duplex ultrasound. Procedural failure and EHIT rates were considered primary outcomes. RESULTS: There was no difference in EHIT or failure rates between study and control groups (P = 1.00). There was no difference in EHIT or failure rates between patients with and without the history of venous thromboembolism (VTE), with and without the history of VTE and/or SVT, with and without the history of thrombophilia, and on and off anticoagulation for either group or the combined study population. For the combined study population, failure rate was higher in patients with a history of VTE. CONCLUSIONS: Although EVA seems to be safe and effective in patients with a history of SVT, vein access in this patient group might require multiple attempts.
