BACKGROUND: The MMP (matrix metalloproteinase) family plays diverse and critical roles in directing vascular wall remodeling in atherosclerosis. Unlike secreted-type MMPs, a member of the membrane-type MMP family, MT1-MMP (membrane-type 1 MMP; MMP14), mediates pericellular extracellular matrix degradation that is indispensable for maintaining physiological extracellular matrix homeostasis. However, given the premature mortality exhibited by MT1-MMP-null mice, the potential role of the proteinase in atherogenesis remains elusive...

John T Sigalos, Alexander W Pastuszak
Chronic orchialgia is a vexing condition defined as chronic or intermittent scrotal pain lasting at least three months that significantly interferes with daily activities. There are currently no guidelines regarding the diagnosis and management of this condition despite it being the cause of 2.5-4.8% of urologic clinic visits. Men often present with chronic orchialgia in their mid to late 30s, although the condition can present at any age. A broad differential diagnosis of chronic orchialgia includes epididymitis, testicular torsion, tumors, obstruction, varicocele, epididymal cysts, hydrocele, iatrogenic injury following vasectomy or hernia repair, and referred pain from a variety of sources including mid-ureteral stone, indirect inguinal hernia, aortic or common iliac artery aneurysms, lower back disorders, interstitial cystitis, and nerve entrapment due to perineural fibrosis; approximately 25-50% of chronic orchialgia is idiopathic in nature...

BACKGROUND: Horton's disease is a systemic inflammatory vasculitis, usually found in persons over 50years old. It affects medium and large-sized arteries stemming from the external carotid, especially the superficial temporal arteries. It can affect extracranial large vessels but only rarely the aorta. Diagnosis of aortitis is difficult and its incidence is probably underestimated. CASE PRESENTATION: A 68-year-old Caucasian woman consulted in an emergency department for febrile abdominal pain with inflammatory syndrome...

A total of 576 patients underwent endovascular aneurysm repair using main body devices for treatment of abdominal aortic aneurysms or iliac artery aneurysms. During follow-up, type IIIb endoleaks caused by fabric tear occurred in six patients (1.0% [6/576]). The device used was Zenith (Cook Medical, Bloomington, Ind) in five cases and Talent (Medtronic, Santa Rosa, Calif) in one case. All endoleaks were close to the flow divider of the main body devices. The distance between the lower renal artery and the top end of the contralateral leg was 53 ± 14 mm...

OBJECTIVE: This study evaluated the morbidity of endovascular abdominal aortic aneurysm repair (EVAR) in patients with concomitant common iliac artery aneurysm (CCIAA). METHODS: This was a retrospective review of all patients who underwent elective EVAR from June 2006 through June 2012 at a single institution. Demographics, comorbidities, preoperative presentation, intraoperative details, and postoperative complications were tabulated. Patients with CCIAA were categorized into three groups according to the distal extent of their iliac limb: iliac limb extension into the external iliac artery with internal iliac artery coil embolization (EE); flared iliac limb ≥20 mm in diameter to the iliac bifurcation (FL); and iliac limb ≤20 mm ending proximal to the CCIAA (no-FL)...

INTRODUCTION: Re-interventions are still the Achilles' heel of endovascular aneurysm repair (EVAR). Ectatic common iliac arteries (CIA) can be treated with flared iliac limbs but a dilated artery used as sealing zone could increase the risk of a late type 1b endoleak. The aim of the present analysis was to evaluate the risk of late type 1b endoleak after EVAR in patients with CIA limbs ≥20 mm compared with those <20 mm. METHODS: A retrospective analysis was performed of patients treated by EVAR at the study institution between 2006 and 2012, including patients with available information about the type of iliac stent grafts and a minimum follow-up (FU) of 3 years with contrast enhanced CT, or those that had developed a type 1b endoleak earlier...

A 69-year-old man was referred urgently for a 58-mm enlarging painful right internal iliac artery (IIA) aneurysm. Since exclusion through proximal IIA coverage and distal IIA branches embolization had been previously performed, aneurysm sac puncture through the iliac vein was decided. The ipsilateral common femoral vein was antegradely punctured, and a 16.5 G Ross modified Colapinto needle from a transjugular intrahepatic access set was used to puncture the sac and fill the aneurysm with coils. Embolization of an IIA aneurysm through the iliac vein may represent an alternative when prior IIA aneurysm exclusion has been performed...

BACKGROUND: Endovascular aneurysm repair of aortoiliac or iliac aneurysms is often performed with stent graft coverage of the origin of the hypogastric artery (HA) to ensure adequate distal seal. It is considered common practice to perform adjunctive coiling of the HA to prevent a type II endoleak. Our objective was to question the necessity of pre-emptive coiling by comparing the outcomes of HA coverage with and without prior coil embolization. METHODS: Data from the Endurant Stent Graft Natural Selection Global Postmarket Registry (ENGAGE), which prospectively enrolled 1263 endovascular aneurysm repair patients between March 2009 and April 2011 from multiple centers worldwide, were used for this study...

BACKGROUND: The cumulative amount of iodinated-contrast-medium necessary for EVAR planning, operative procedure and subsequent follow-up is a threat for the onset of end stage renal disease in patients with pre-operative impaired kidney function. Purpose of this study is to describe a mini-invasive approach aimed to minimize the exposure of these patients to iodinated-contrast-medium and the subsequent risk of renal function worsening. METHODS: From 2012 to 2015, all patients with abdominal aortic aneurysm (AAA) at high-surgical risk and fit for standard endovascular repair (simple aortic-iliac anatomy: proximal and distal neck length ≥15mm, no severe angulation), underwent EVAR through the following "near-zero contrast" approach, if their glomerular filtration rate (GFR) was <30 mL/min: pre-operative planning was performed by non-contrast enhanced computed tomography (CT) and duplex-ultrasound (DU); the origin of renal/hypogastric arteries and aortic bifurcation was evaluated and matched with vertebral bone landmarks and the endograft deployed accordingly, using < 20cc of isotonic iodinate-contrast-medium and contrast-enhancement-DU (CEUS)...

BACKGROUND: There is no international consensus regarding the optimum management of infected aortae (mycotic aneurysms, infected aortic grafts). Neoaortoiliac reconstruction has advantages over extra-anatomical bypass grafting; however, the use of autologous vein is associated with venous hypertension and compartment syndrome, alternatively cadaveric homografts are associated with high rates of perianastomotic hemorrhage, limb occlusion, and pseudoaneurysm. Arterial repair using xenoprosthetic patches is associated with lower infection rates compared to the use of prosthetic material...
