OBJECTIVE: Short neck length, and angulated infrarenal aortic necks, are historically associated with sac expansion following endovascular abdominal aortic aneurysm repair. Aorfix (Lombard Medical, Inc, Irvine, Calif), a conformable stent graft US Food and Drug Administration approved for highly angulated necks, was investigated in the US Pythagoras Trial. We investigated the incidence of, and factors related to, sac regression and expansion following implantation of the Aorfix device...

OBJECTIVE: Early and midterm outcomes of the Prospective Aneurysm Trial: High Angle Aorfix Bifurcated Stent Graft (PYTHAGORAS) trial in patients with highly angulated aortic necks (≥60 degrees) have already been published and shown comparable outcomes to other endografts in normal anatomy. Herein, we present the long-term outcomes of the PYTHAGORAS trial of Aorfix (Lombard Medical, Irvine, Calif) for patients with highly angulated aortic neck anatomy. METHODS: The Aorfix endograft is a highly conformable nitinol/polyester device designed for transrenal fixation...

OBJECTIVE: Extended-field chemoradiation is typically used for the management of patients with locally advanced cervical cancer. Given the low rate of skipped metastases above the inferior mesenteric artery, ilioinframesenteric dissection seems to be an acceptable pattern of paraaortic lymph node dissection (LND). Our objective is to compare the surgical morbidity of inframesenteric LND (IM-LND) with infrarenal LND (IR-LND). METHODS: In our center, all of the patients with locally advanced cervical cancer and negative magnetic resonance imaging and positron emission tomography-computed tomography imaging at the paraaortic level were offered laparoscopic staging including a diagnostic laparoscopy followed, if negative, by an extraperitoneal paraaortic lymphadenectomy...

Inferior vena cava (IVC) thrombosis is a rare complication of abdominal aortic aneurysm (AAA). A 70-year-old male patient of Italian origin presented with a 9.3 x 8.4 cm infrarenal AAA, which was treated by endovascular aortic repair (EVAR). He reported a history of ulcerative colitis and was on prednisolone 80 mg daily. Seven weeks postoperatively the patient was readmitted with a deep vein thrombosis including both iliac veins and IVC, and bilateral pulmonary embolism. Venous thrombectomy and decompression of the IVC was performed by partial resection of the aneurysm sac...

Arterial manifestation of Behçet disease represents a challenging clinical scenario with a potential for fatal complications. This case depicts the surgical management of a 4.5-cm infrarenal aortic aneurysm and a 6-cm left renal artery aneurysm in a patient with known Behçet disease. The presence of a contralateral living donor kidney transplant added to the complexity of the case. Open surgical repair was performed on both aneurysms with the use of axillofemoral bypass to protect the transplanted kidney...

BACKGROUND: Many patients with complex abdominal aortic aneurysms are unfit for open repair. New endovascular technologies and bailout techniques are being used for managing those complex anatomies. The purpose of this study is to compare the results obtained with advanced endovascular aneurysm repair techniques (fenestrated and chimney endografts) to those obtained with open repair for the treatment of complex abdominal aortic aneurysms not anatomically suitable for standard endovascular exclusion (infrarenal neck <10 mm, juxtarenal, suprarenal and Crawford's type IV thoracoabdominal aneurysms)...

Abdominal aortic aneurysms (AAAs) represent a potentially life-threatening condition that predominantly affects the infrarenal aorta. Several preclinical murine models that mimic the human condition have been developed and are now widely used to investigate AAA pathogenesis. Cell- or pharmaceutical-based therapeutics designed to prevent AAA expansion are currently being evaluated with these animal models, but more minimally invasive strategies for delivery could improve their clinical translation. The purpose of this study was to investigate the use of self-assembling type I collagen oligomers as an injectable therapeutic delivery vehicle in mice...

Type B aortic dissection (TBAD) can be complicated due to visceral and limb malperfusion. We present the case of a patient with a TBAD 5 months after endovascular aneurysm repair (EVAR) for an infrarenal aortic aneurysm, which resulted in a right leg acute limb ischemia due to impingement of the EVAR from to the dissection. In the following discussion, we will review the literature and describe our technique for the treatment of this infrequent problem.

The duplication of the inferior vena cava (IVC) is a rare congenital anomaly, which also has some variations regarding the complex embryological development of the IVC. In the typical form, infrarenal IVC segments are duplicated and the left IVC joins the left renal vein, which crosses anterior to the aorta in the normal fashion to join the right IVC. In variant forms, the interruption of the intrahepatic segment of the IVC, azygos or hemiazygos continuation, or retroaortic course of the renal vein may be seen...

A 50-year-old male smoker presented with a perforated colon cancer and underwent an extended right colectomy. Feculent peritonitis was treated with empiric antibiotics. Postoperatively he developed severe back pain and rising leukocytosis. Serial computed tomography revealed a rapidly expanding infrarenal aortic aneurysm. He was urgently treated with extra-anatomic bypasses and aortic resection. No organisms grew from the resected aortic wall. He was discharged in stable condition, and the ileostomy was reversed 9 months later...

OBJECTIVE: Endovascular aneurysm repair (EVAR) has progressively expanded to treat more challenging anatomies. Although EVAR in patients with wide infrarenal necks has been reported with acceptable results, there is still controversy regarding the longer-term outcomes. Our aim is to determine the impact of infrarenal neck diameter on midterm outcome following EVAR with a single endograft with suprarenal fixation. METHODS: A retrospective case-control study was designed using data from a prospective multicenter database...

OBJECTIVE/BACKGROUND: Neointimal hyperplasia (NIH) remains one of the leading causes of graft failure after vascular anastomoses. Cytotoxic drugs, such as rapamycin and tacrolimus, have been shown to inhibit the development of NIH. In this study, the aim was to test the impact of a sustained releasing tacrolimus-chitosan-eluting suture on the development of NIH in a rat model. METHODS: After tacrolimus-chitosan coating of a 7/0 polyvinylidene difluoride (PVDF) Trofilen(®) suture, the tacrolimus concentration on the coated suture and in vitro release trials were performed spectrophotometrically...

AIMS: Inflammation drives atherosclerosis complications and is a promising therapeutic target for plaque stabilization. At present, it is unknown whether local stenting approaches can stabilize plaque inflammation in vivo. Here, we investigate whether everolimus-eluting stents (EES) can locally suppress plaque inflammatory protease activity in vivo using intravascular near-infrared fluorescence (NIRF) molecular imaging. METHODS AND RESULTS: Balloon-injured, hyperlipidaemic rabbits with atherosclerosis received non-overlapping EES and bare metal stents (BMS) placement into the infrarenal aorta (n = 7 EES, n = 7 BMS, 3...

PURPOSE: To investigate safety and efficacy of hybrid treatment for infected aortic and iliac aneurysms. MATERIALS AND METHODS: Between July 2007 and May 2011, hybrid treatment was performed in 6 male patients (mean age, 67.7 y; range, 57-76 y). Hybrid treatment consisted of extraanatomic bypass (EAB) and isolation of infected aneurysm with vascular plugs. Aneurysms were divided into primary and secondary infected aneurysms. Primary infected aneurysm refers to an aneurysm arising from bacterial infection of the native arterial wall; secondary infected aneurysm refers to infection involving an aneurysm that was previously treated with graft placement...
