infrarenal abdominal aorta occlusion

Objective: To examine the efficacy and experience of staged and segmented two hybrid surgeries for total repair of Debakey type Ⅰ aortic dissection (TIAD). Methods: This study was a retrospective case series. The clinic data of 10 patients with acute TIAD who were admitted to the Department of Cardiac Surgery, Second Hospital of Lanzhou University or the First People's Hospital of Lanzhou, between January 2016 and August 2022, were retrospectively studied. Ten patients underwent hybrid surgeries in two hospitalizations (stages), including 7 males and 3 females with an age of (60±7) years (range: 49 to 71 years)...

BACKGROUND: Juxtarenal aortic occlusion (JRAO), in which the occlusion of the aorta extends to just below the renal artery, is often treated by bypass surgery because of concerns about the risk of procedural failure and fatal embolization to abdominal organs when treated with endovascular treatment (EVT). This study assessed the outcome of EVT for JRAO compared with aorto-biiliac /aorto-bifemoral (AOB) or axillo-bifemoral (AXB) bypass. METHODS: A retrospective review of an international database created by 30 centers in Asia (CHronic Abdominal Aortic Occlusion, ASian Multicenter registry) was performed for patients who underwent revascularization for chronic total occlusion of the infrarenal aorta from 2007 to 2017...

BACKGROUND: Chronic mesenteric ischemia (CMI) is a debilitating disease with a heavy burden on quality of life. Stenting of the superior mesenteric artery (SMA) is the first option for treatment, but there is a lack of consensus defining precise indications for open revascularization (OR). OBJECTIVES: To describe a series of 4 patients with CMI treated with OR and to present an algorithm for the management of this condition. METHODS: Three patients presented with typical intestinal angina and weight loss...

The incidence of esophagogastric junction cancer has been increasing, leading to growing interest in surgical treatment. Leriche syndrome, characterized by occlusion limited to the infrarenal aorta, has not been reported to be associated with ischemic enteritis, and there are no previous reports on the surgical approaches for esophagogastric junction cancer in this disease.We describe the case of a male patient in his fifties with lower abdominal pain and melena who was diagnosed with esophagogastric junction cancer, Leriche syndrome, and ischemic enteritis...

INTRODUCTION AND IMPORTANCE: Mesenteric artery stenosis leads to inadequate blood flow toward various parts of the gastrointestinal tract. Revascularization is the primary aim of treatment regardless of its approach. During the last decades, open revascularization has been replaced by endovascular-first approach. Mesenteric artery in-stent restenosis occurs in a considerable number of patients that need reintervention in up to half of them using redo endovascular revascularization or open surgery...

OBJECTIVE: Chronic abdominal aortic occlusive disease (CAAOD) is an uncommon manifestation of antiphospholipid syndrome (APS), impacting cardiovascular health and peripheral arterial circulation. We investigated CAAOD in antiphospholipid antibodies (aPL)-positive patients, aimed to offer comprehensive clinical and radiological insights. METHODS: aPL-positive patients with arterial thrombotic events were categorised into CAAOD and non-CAAOD. Extensive data, including clinical features, radiological images and outcomes, were analysed...

BACKGROUND: Abdominal aortic occlusion (AAO) occurs frequently and causes ischemia/reperfusion (I/R) injury to distant organs. In this study, we aimed to investigate whether AAO induced I/R injury and subsequent damage in cardiac and neurologic tissue. We also aimed to investigate the how length of ischemic time in AAO influences reactive oxygen species (ROS) production and inflammatory marker levels in the heart, brain, and serum. METHODS: Sixty male C57BL/6 mice were used in this study...

Aortoiliac occlusive disease (AIOD), also known as Leriche syndrome, is a form of peripheral artery disease (PAD) that involves narrowing, and in severe cases, complete occlusion, of infrarenal abdominal aorta and/or iliac and femoropopliteal arteries. It classically presents as a triad of symptoms, i.e., leg pain, erectile dysfunction, and abnormally weak or absent femoral pulses. If untreated, it can progress to ischemia and gangrene of the affected regions of pelvis and lower extremities. Like any other PAD, AIOD is most commonly caused by atherosclerosis and usually occurs in strong association with severe cardiovascular diseases...

Leriche syndrome is an aortoiliac occlusive arterial disease comprising decreased peripheral pulses, claudication, and erectile dysfunction. We present a case of a 60-year-old male with abdominal pain and hematochezia who was diagnosed with hemorrhoids. The patient also had associated leg cramps on both sides and lower limb weakness. Further evaluation of the patient with imaging revealed occlusion of the distal descending abdominal aorta below the level of renal arteries and the iliac arteries. An incidental finding of Leriche syndrome was evident...

Purpose  The aim of this study was to evaluate the effectiveness of the proposed method of preventive embolization of the internal iliac arteries using a liquid tantalum-containing ethylene vinyl alcohol copolymer. Methods  In this nonrandomized clinical study with a retrospective control group, 55 patients with aneurysmal lesions of the infrarenal abdominal aorta participated. In the course of this study, we developed and implemented a method of preventive embolization of the ostia of the internal iliac artery using a liquid tantalum containing ethylene-vinyl alcohol copolymer having viscosity of 34 centipoise...

A 67-year-old male patient required surgical management of an abdominal aortic aneurysm. Contrast-enhanced computed tomography showed a saccular infrarenal abdominal aortic aneurysm and occlusion of the origins of the celiac artery, superior mesenteric artery, and inferior mesenteric artery. Aortography revealed large amounts of blood flow from capillaries around the abdominal aorta to the inferior mesenteric artery and retrograde blood flow to a meandering mesenteric artery through the superior rectal artery...

Immune thrombocytopenia (ITP) is an autoimmune blood disorder characterised by isolated severe thrombocytopenia. Arterial thrombotic events, such as acute ischaemic stroke (AIS), are rare complications. A 56-year-old woman with chronic ITP on eltrombopag and dexamethasone therapy presented to the emergency department due to AIS in the vertebrobasilar territory, and lower abdominal pain. The computed tomography (CT) scan of the head was unremarkable, whereas CT angiography revealed left vertebral artery occlusion...

INTRODUCTION: Noncompressible torso hemorrhage (NCTH) accounts for most potentially survivable deaths on the battlefield. Treatment of NCTH is challenging, especially in far-forward environments with limited capabilities. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has shown promise in the care of patients with NCTH. REBOA involves introducing a balloon catheter into the descending aorta in a specific occlusion region (zones 1, 2, or 3) and acts as a hemorrhage control adjunct with resuscitative support...

Acute aortic dissection in the immediate postoperative period after endovascular abdominal aortic aneurysm repair (EVAR) has been linked to technical factors such as excessive endograft oversizing or aortic wall injuries during the procedure. In contrast, dissections that occur later are more likely to be de novo. Regardless of their etiology, aortic dissection can extend into the abdominal aorta, causing collapse and occlusion of the endograft with devastating complications. To the best of our knowledge, no studies have reported on aortic dissection in EVAR patients in whom EndoAnchors (Medtronic, Minneapolis, MN) had been used...

BACKGROUND: Abdominal aortic aneurysms (AAAs) and peripheral artery disease significantly increase the risk of perioperative complications. AIM: To determine the incidence, association with 30-day mortality and predictors of myocardial injury after noncardiac surgery (MINS), postoperative acute kidney injury (pAKI) and bleeding independently associated with mortality (BIMS) in patients undergoing open vascular surgeries involving abdominal aorta. METHODS: We performed a retrospective cohort study using a sample of consecutive patients who underwent open abdominal aortic surgery due to infrarenal AAA and/or aortoiliac occlusive disease in a single tertiary center...

Leriche syndrome, a rare and critical complication of peripheral arterial disease (PAD), affects the distal abdominal aorta (infrarenal) and, similar to PAD, is a result of plaque buildup in the arterial lumen. The Leriche syndrome triad includes claudication in the proximal lower extremity, decreased or absent femoral pulses, and, in some cases, impotence. This article presents a patient with an atypical presentation of foot pain who was subsequently found to have Leriche syndrome. The patient was a 59-year-old female, a former smoker, who presented to the emergency department (ED) with atraumatic, acute right foot pain...

Distal aortic occlusion is rare; and because many cases are left undetected due to an asymptomatic early stage, its prevalence is currently unknown. In this report, we present a case of a 53-year-old man with history of hypertension and tobacco usage who was referred to our ambulatory imaging center for advanced computerized tomography (CT) urography evaluation after presenting abdominal pain consistent with renal calculi. The CT urography showed left kidney stones - confirming the initial clinical suspicion of the referring physician...

UNLABELLED: Primary aortic occlusion (PAO) is defined as acute occlusion in the absence of aortic atherosclerosis or aneurysm. PAO is a rare disease with acute onset and can determine massive parenchymal ischemia and distal arterial embolization. The aim of our study was to focus on the assessment of clinical characteristic, CT signs, medical and surgical treatment, complication rates and the overall survival of PAO. MATERIALS AND METHODS: We retrospectively analyzed the data of all patients with acute lower limb ischemia and a final surgical or discharge diagnosis of PAO who underwent aortic CT angiography in ER settings in our hospital from January 2019 to November 2022...

Placenta accreta spectrum (PAS) disorder is one of the most dangerous conditions that can affect pregnancy and its incidence is increasing secondary to rising cesarean section rates worldwide. The standard treatment is frequently elective hysterectomy at the time of cesarean delivery; however, uterine and fertility preserving surgery is becoming more common. In the pursuit of a reduction in blood loss and associated maternal morbidity, occlusive vascular balloons are increasingly used at the time of surgery, usually placed with fluoroscopic guidance...

BACKGROUND: The purpose of this study was to investigate if the duration of bilateral acute limb ischaemia (BALI) caused by acute aortic occlusion (AAO) affected amputation-free survival. MATERIALS AND METHODS: A retrospective analysis of patients treated between 1 January 2010 and 1 January 2019 for primary occlusion of the infrarenal aorta and BALI was performed. Univariate analysis was used to determine the risk factors for adverse outcomes and compare the duration of BALI between the amputation-free survival and non-amputation-free survival groups...
