Infectious pseudoaneurysm (IPA) is a rare but devastating complication following renal transplantation that typically leads to graft loss and occasionally patient death. IPAs following kidney transplantation are most often mycotic in etiology, but have been sporadically reported to result from Pseudomonas aeruginosa infection. These IPAs occur at various anatomic sites, most commonly at the vascular anastomosis or iliac artery, and very rarely in the transplanted renal artery or hilum. Here we report the occurrence of single donor-derived P aeruginosa IPAs in two kidney transplant recipients with divergent allograft outcomes...

Primary aortoduodenal fistula (ADF) is a direct communication between the abdominal aorta and the gastrointestinal tract without any previous vascular intervention and represents a rare but critical cause of repeated and massive gastrointestinal bleeding. Primary ADF often occurs as a result of atherosclerotic aneurysm and infection, but ADF involving a normal-size aorta is rare; furthermore, ADF related to radiation therapy is extremely rare. We present the case of a 56-year-old man with a history of bowel obstruction due to radiation enteritis who was admitted with severe hematemesis and hemorrhagic shock...

A tailored therapy to patient requirements by combining endovascular and surgical steps can be necessary to prolong the life of a vascular access. Stent grafts play a growing role for the therapy of dialytic access complications. Randomized multi-center trials, however, support the on-label use of stent grafts in the treatment of graft venous outflow and in-stent restenosis. The main contraindication to their use is an ongoing infection. We report two cases of new off-label application of Viabahn (Gore, flagstaff, USA) stent graft...

BACKGROUND: The endovascular management of arterial injuries has resulted in reduced operating time, blood loss, hospital mortality, lower incidence of sepsis, and decrease in mortality rates. For penetrating trauma, however, the benefits of endovascular therapy are questionable. PATIENTS AND METHODS: Data were obtained by retrospective analysis of electronic medical records. All patients with vascular trauma seeking care at our institution from January 2010 to December 2015 were reviewed...

OBJECTIVES: Vascular injury is a rare complication of spinal instrumentation. Presentation can vary from immediate hemorrhage to pseudoaneurysm formation. In the literature, surgical approach to repair has varied based on anatomy, acuity of diagnosis, infection, and available technology. In this manuscript, we aim to describe our institutional experience with vascular injuries in thoraco-lumbar spine surgery. PATIENTS AND METHODS: We report our institutional experience of three cases of vascular injury secondary to pedicle screw misplacement and their management, as well as a review of the literature...

BACKGROUND: Endovascular repair for mycotic aortic aneurysm (MAA) is a less invasive alternative to open surgery, although the placement of a stent graft in an infected environment remains controversial. In this study, we developed hybrid biodegradable, vancomycin-eluting, nanofiber-loaded endovascular prostheses and evaluated antibiotic release from the endovascular prostheses both in vitro and in vivo. METHODS: Poly(D,L)-lactide-co-glycolide and vancomycin were dissolved in 1,1,1,3,3,3-hexafluoro-2-propanol...

Infection of a vascular prosthesis or endovascular stent-graft is probably the most serious complication that may occur after implantation and dramatically affects the patient's outcome. The most common etiology of graft and/or prosthetic valve infection is usually wound-related infection, followed by seeding from distant infection sites (lung, urinary tract). Surgical treatment is almost always required but even after surgery, morbidity can be significant. Operative procedure must be tailored according to the individual patient and to the experience of the surgical team...

INTRODUCTION: A 75-year-old male patient with significant cardiopulmonary comorbidity presented with a 70-mm left femoral pseudoaneurysm 6 years after aortobifemoral bypass (and prior femoral endarterectomy). REPORT: As the left superficial femoral artery was occluded, an ilioprofunda endobypass was undertaken following extraperitoneal exposure of the left limb of the bypass graft with subsequent deployment of four Viabahn endoprostheses via the left limb into the proximal left deep femoral artery with successful exclusion of the pseudoaneurysm...

The arteriovenous graft (AVG) is one of the major types of permanent vascular access used to provide hemodialysis. Complications encountered with AVG use include stenosis, infection, thrombosis, and pseudoaneurysm formation. Venous outflow stenosis along with frequent needle cannulation at the same site can lead to breakdown of the graft material, resulting in pseudoaneurysm formation. In the following case, we illustrate common management principles used to treat pseudoaneurysms. While stent-grafts have been utilized for pseudoaneurysm repair, stent-graft usage is not always optimal...

BACKGROUND: Subclavian and axillary artery injuries are uncommon. In addition to many open vascular repairs, endovascular techniques are used for definitive repair or vascular control of these anatomically challenging injuries. The aim of this study was to determine the relative roles of endovascular and open techniques in the management of subclavian and axillary artery injuries comparing hospital outcomes, and long-term limb viability. METHODS: A multicenter, retrospective review of patients with subclavian or axillary artery injuries from 1/1/2004-12/31/2014 was completed at 11 participating Western Trauma Association institutions...

OBJECTIVE: Central vein occlusion is a common complication related to central vein catheter insertion for haemodialysis which can be unmasked by an ipsilateral fistula creation, leading to a dysfunctional arteriovenous fistula (AVF). We describe an extra-anatomical venous bypass surgical procedure performed to maintain vascular access and reduce the symptoms of swelling of the ipsilateral upper limb, neck and face. MATERIALS AND METHODS: We report 20 consecutive patients with end-stage renal failure (ESRF) who had central vein occlusion and were not amenable to endovascular intervention...

We report a patient who developed ileus caused by vascular stent migration into the duodenum with periprosthetic retroperitoneal abscess. The patient previously underwent removal of an infected abdominal aortic aneurysm with concomitant axillobifemoral arterial reconstruction. An occlusion of the graft leg was treated by a unilateral aortoiliac bypass where endovascular surgery with a metallic stent was later needed. The abscess and ileus were vigorously drained. Following the spontaneous evacuation of the metallic stent via the digestive tract, the abscess was completely drained and fistula closure was achieved without surgical intervention...

False aneurysms are formed as a result of bleeding causing a hematoma to compress the surrounding tissue. The majority of false aneurysms presenting to the vascular surgeon are caused by iatrogenic injury to an artery. Although anastomotic failure occurs, a much higher number is caused by bleeding from puncture sites after percutaneous intervention. Anticoagulative medication, low patelet counts and severely calcified vessels increase the risk of forming a false aneurysm. Experienced specialists may make the diagnosis from physical examination, but ultrasound imaging is almost always needed in order to decide for a treatment strategy...

BACKGROUND: No reliable comparative data exist between open repair (OR) and endovascular aneurysm repair (EVAR) for mycotic abdominal aortic aneurysms (MAAAs). This nationwide study assessed outcomes after OR and EVAR for MAAA in a population-based cohort. METHODS: All patients treated for MAAAs in Sweden between 1994 and 2014 were identified in the Swedish vascular registry. The primary aim was to assess survival after MAAA with OR and EVAR. Secondary aims were analyses of the rate of recurrent infections and reoperations, and time trends in surgical treatment...

OBJECTIVE/BACKGROUND: The management of aortic graft infection (AGI) is highly complex and in the absence of a universally accepted case definition and evidence-based guidelines, clinical approaches and outcomes vary widely. The objective was to define precise criteria for diagnosing AGI. METHODS: A process of expert review and consensus, involving formal collaboration between vascular surgeons, infection specialists, and radiologists from several English National Health Service hospital Trusts with large vascular services (Management of Aortic Graft Infection Collaboration [MAGIC]), produced the definition...

Peripheral vascular injuries carry significant risk for permanent functional impairment, limb loss, and death. Definitive correction of these injuries requires significant operative time and has traditionally been resource and skill set intensive. In the initial surgical treatment of the physiologically depleted trauma patient, faster techniques may prove more appropriate. Damage control techniques, including vascular shunting, rapidly restore distal flow but require additional vascular intervention and risk shunt thrombosis with prolonged use...
