Purpose: To present the first case of colonic ischemia (CI) after endovascular exclusion of an aortoiliac aneurysm using an iliac branch device (IBD). Case report: A 69-year-old male patient with an abdominal aortic and right common iliac artery aneurysm underwent endovascular repair with an IBD. Completion angiography demonstrated good patency in 2 of the 3 main branches of the right internal iliac artery (IIA) whereas the left IIA patency was preserved. Preoperatively, the inferior mesenteric artery (IMA) was patent. Postoperatively, the patient presented moderate CI. He was treated conservatively and discharged 15 days later with recession of the symptoms. Conclusion: Although preservation of bilateral iliac artery patency is considered to diminish the incidence of pelvic ischemia, in case of an exclusion of a patent IMA, collaterals may not be adequate to ensure blood supply to the left colon ...

Objectives To quantify the deformation of the common iliac artery caused by stiff guide wires and delivery systems during abdominal endovascular aortic repair (EVAR). Methods Twenty-two patients treated with abdominal EVAR were included. The following three image data-sets were acquired for each patient: (1) a preoperative computed tomography angiography (CTA), (2) an intraoperative contrast-enhanced cone beam CT (CBCT) obtained after the main trunk of the bifurcated stent graft was released and both iliac limbs were engaged with stiff guide wires, and (3) the first postoperative CTA. These data-sets were merged and compared in an image analysis work station. The length and the tortuosity index of the common iliac artery, the Euclidian displacement of the aortic and the iliac bifurcations, and the optimal C-arm angulation for projection of the iliac bifurcation were computed. Results The common iliac artery was on average 6.4 mm shorter (p < 0.001) and tortuosity index was lower (p = 0.003) in ...

The common iliac arteries are two large arteries that originate from the aortic bifurcation at the level of the fourth lumbar vertebra. They end in front of the sacroiliac joint, one on either side, and each bifurcates into the external and internal iliac arteries. They are about 4 cm long in adults and more than a centimeter in diameter. The arteries run inferolaterally, along the medial border of the psoas muscles to their bifurcation at the pelvic brim, in front of the sacroiliac joints. The common iliac artery, and all of its branches, exist as paired structures (that is to say, there is one on the left side and one on the right). The distribution of the common iliac artery is basically the pelvis and lower limb (as the femoral artery) on the corresponding side. Both common iliac arteries are accompanied along their course by the two common iliac veins which lie posteriorly and to the right. Their terminal bifurcation is crossed anteriorly by the ureters. Deep and superficial dissection of ...
A 54-year-old man with remote large cell non-Hodgkins lymphoma in remission following R-CHOP and severe atopic dermatitis was transferred from another hospital with a non-ST elevation myocardial infarction. Over the preceding year, the patient had suffered recurrent admissions for acutely decompensated heart failure with a newly depressed left ventricular ejection fraction (LVEF) of 20% by echocardiography and rapidly progressive end-stage renal disease of unclear etiology requiring the initiation of hemodialysis. Prior workup had demonstrated an infrarenal abdominal aortic aneurysm and bilateral common iliac artery aneurysms with subsequent computed tomography (CT) additionally demonstrating a superior mesenteric artery aneurysm. The patient was taken for immediate coronary arteriography, which demonstrated giant aneurysms in the left main and right coronary arteries, as well as multivessel severe stenoses. CT coronary angiogram demonstrated significant circumferential wall thickening ...

The characterization of blood flow is important to establish links between the hemodynamics and the occurrence of cardiovascular diseases. This study describes the development of a 3-D computational model able to predict the blood flow along the abdominal aorta, including the renal and iliac branches. Upstream branches in the abdominal aorta lead to more complex flow patterns downstream, intensifying reverse and asymmetric flow patterns. The focus is on the occurrence of reverse flow and the perturbations in blood flow patterns originated by the branches. Results show regions of recirculation in the walls of the abdominal aorta, renal and iliac branches. It is concluded that, the renal branches induces perturbations in blood flow and result in asymmetric velocity profiles.. Copyright © 2008 by ASME ...
The external iliac artery provides the main blood supply to the legs. It passes down along the brim of the pelvis and divides into two large branches - the inferior epigastric artery and a deep circumflex artery. These vessels supply blood to the muscles and skin in the lower abdominal wall. The external iliac artery passes beneath the inguinal ligament in the lower part of the abdomen and becomes Continue Scrolling To Read More Below... ...

A 72-year-old man suffering from congestive heart failure, swelling of the lower limbs and hematuria was transferred from another hospital with a diagnosis of large aneurysms of the abdominal aorta and the left common iliac artery. Iliac arteriovenous fistula (AVF) was definitively diagnosed preoperatively by contrast-enhanced CT and angiogaphy. At operation, an infrarenal abdominal aortic aneurysm of 8cm and left iliac arterial aneurysm of 12cm were identified. After proximal and distal aortic clamping, the aneurysm was entered and an AVF orifice of 1cm communicating with the left common iliac vein was disclosed at the right posterior wall of the left common iliac artery. Venous blood reflux was controlled by inserting an occlusive balloon catheter to the fistula and intraoperative shed blood was aspirated and returned by an autotransfusion system. The AVF was closed from inside the iliac aneurysm by three interrupted 3-0 monofilament mattress sutures with pledgets. The aneurysms were resected ...
An EVAR often requires multiple wires and catheters be transferred into the vessel via an introducer sheath, which can lead to blood loss through the sheath valve. The sheaths exclusive DrySeal valve is designed to minimise blood loss, enabling the introduction of multiple devices with haemostasis control.. "Nearly a third of patients being considered for EVAR have an aneurysm that extends to the iliac artery. The Excluder device is a trusted solution in such cases, but previously no introducer sheaths designed for use with this device existed," said Marcus Brooks, consultant vascular surgeon, North Bristol NHS Trust, UK. "With the Gore DrySeal Flex introducer sheath, I now have a sheath specifically designed for use with the iliac branch endoprosthesis and flexible enough for easy access to the iliac branch vessels.". The new sheath leverages technology from Gores DrySeal Sheath, which features a hydrophilic coating for improved access into vessels. In addition, the DrySeal sheath offers an ...
A 67-year-old man with critical limb ischemia due to left common iliac artery (CIA) occlusion underwent endovascular treatment and stent deployment (Express LD, 8.0 × 37 mm and 8.0 × 17 mm, Boston Scientific, Natick, Massachusetts) (Figure 1). The symptoms of ischemia resolved after stent implantation; however, the patient felt pain while at rest in the left leg 3 years later. Angiography indicated a totally occluded left CIA at the stent site. Computed tomography angiography (CTA) revealed that the stent in the left CIA was compressed by a spinal spur (Figure 2). We speculate that the following occurred. The spinal spur gradually compressed the balloon-expandable stent as the patient performed normal daily activities; eventually, it caused the stent to fracture, causing CIA reocclusion. We performed bypass surgery between the femoral arteries to obtain sufficient blood flow to the left leg, and the patients pain was relieved. Stent implantation for stenosis of the iliac arteries is an ...

PURPOSE To present a novel technique for endovascular repair of abdominal aortic aneurysms (AAA) in patients with an occluded iliac artery on one side. TECHNIQUE In patients with an occluded iliac artery, the main body of a bifurcated modular endoprosthesis is deployed in standard fashion. Another stent-graft of a similar diameter is placed inside the deployed device so that the proximal end of the second endograft is a few millimeters caudal to the leading edge of the first device, which positions the second contralateral gate caudal to the flow divider of the first device. The second stent-graft is also rotated so that its contralateral gate is 180 degrees opposite to the contralateral gate of the first device. This stent-graft sandwich effectively mimics an aortomonoiliac device. After deployment of the second device, the attachment sites are dilated with appropriately sized balloons according to standard practice for the particular endoprostheses. CONCLUSIONS Endovascular AAA repair utilizing
Introduction: Iliac artery dissection without aortic involvement is a rare entity, with most cases associated with predisposing factors such as trauma, atherosclerosis, connective tissue disorders or vigorous exercise. The best treatment is not unanimous, and depends on the acuteness and severity of symptoms. Criteria for intervention include prevention of aneurysmatic degeneration, acute limb ischemia, inguinal pain and aneurysm rupture. Recent results using endovascular technique showed comparability with open repair, but there is paucity of data concerning long term results.. Methods: Relevant medical data were collected from hospital database.. Results: The patient is a 65 years old male, referred to the emergency department for abdominal pain in the left lower quadrant with inguinal irradiation. No signs or symptoms of acute limb ischemia were present. He had no previous history of connective tissue disease, cardiovascular risk factors, trauma or vigorous exercise. A CTA was performed, ...
A flexible low profile delivery system for delivery of an expandable intracorporeal device, specifically, an endovascular graft, which has at least one belt circumferentially disposed about the device in a constraining configuration. The belt is released by a release member, such as a release wire, by retracting the wire from looped ends of the belt. Multiple belts can be used and can be released sequentially so as to control the order of release and placement of the endovascular graft. An outer protective sheath may be disposed about the endovascular graft while in a constrained state which must first be retracted or otherwise removed prior to release of the graft from a constrained state. The delivery system can be configured for delivery over a guiding device such as a guidewire. The delivery system can also be configured for delivery of bifurcated intracorporeal devices.
