Staged endovascular treatment of aneurysmal progressive development of an intercostal arteries island reimplanted with the loop-graft technique.

Eur J Cardiothorac Surg 2021 Jun 12. Epub 2021 Jun 12.

Department of Vascular Surgery, Vita-Salute University, San Raffaele Scientific Institute, Milan, Italy.

A staged endovascular strategy was used to treat the aneurysmal evolution of the aortic island including intercostal arteries reimplanted in a loop-graft, following thoraco-abdominal aortic open repair in a young patient diagnosed with Marfan syndrome. First, selective coil embolization of patent intercostal arteries was performed in 2 separate sessions, to minimize the risk of spinal cord ischaemia. Then, the aneurysm was successfully excluded occluding the loop graft with 2 PTFE-membrane vascular plugs. Read More

Pathophysiological Aspects of the Development of Abdominal Aortic Aneurysm with a Special Focus on Mitochondrial Dysfunction and Genetic Associations.

Biomol Concepts 2021 Jun 11;12(1):55-67. Epub 2021 Jun 11.

Department of Basic Research, Institute for Atherosclerosis Research, Moscow121609, Russia.

Abdominal aortic aneurysm (AAA) is a complex degenerative vascular disease, with considerable morbidity and mortality rates among the elderly population. The mortality of AAA is related to aneurysm expansion (the enlargement of the aortic diameter up to 30 mm and above) and the subsequent rupture. The pathogenesis of AAA involves several biological processes, including aortic mural inflammation, oxidative stress, vascular smooth muscle cell apoptosis, elastin depletion, and degradation of the extracellular matrix.

Abdominal Aortic Aneurysm Segmentation Using Convolutional Neural Networks Trained with Images Generated with a Synthetic Shape Model.

Mach Learn Med Eng Cardiovasc Health Intravasc Imaging Comput Assist Stenting (2019) 2019 12;11794:167-174. Epub 2019 Oct 12.

Applied Chest Imaging Laboratory, Brigham and Women's Hospital, Harvard medical school, Boston, USA.

An abdominal aortic aneurysm (AAA) is a ballooning of the abdominal aorta, that if not treated tends to grow and rupture. Computed Tomography Angiography (CTA) is the main imaging modality for the management of AAAs, and segmenting them is essential for AAA rupture risk and disease progression assessment. Previous works have shown that Convolutional Neural Networks (CNNs) can accurately segment AAAs, but have the limitation of requiring large amounts of annotated data to train the networks. Read More

Endovascular interventions in main renal artery pathologies: an overview and update.

Acta Radiol 2021 Jun 9:2841851211019806. Epub 2021 Jun 9.

Department of Imaging Sciences and Interventional Radiology, Sree Chitra Tirunal Institute for Medical Sciences and Technology, Trivandrum, Kerala, India.

Renal arteries are involved in a wide spectrum of pathologies including atherosclerosis, fibromuscular dysplasia, Takayasu arteritis, aneurysms, and aortic type B dissections extending into main renal arteries. They manifest as renovascular hypertension, renal ischemia, and cardiovascular dysfunction. The location of the renal arteries in relation to the abdominal aortic aneurysm is a critical determinant of interventional options and long-term prognosis. Read More

Rev Med Chil 2021 Jan;149(1):132-136

Departamento de Cirugía Vascular y Endovascular, Pontificia Universidad Católica de Chile, Santiago, Chile.

Primary aortoenteric fistula is the spontaneous communication between the lumen of the aorta and a portion of the digestive tract. The most common cause is the erosion of an abdominal aortic aneurysm into the 3rd or 4th portion of the duodenum. It manifests clinically as gastrointestinal bleeding, with or without abdominal pain and a pulsatile abdominal mass on physical exam. Read More

Preemptive VAE-An Important Tool for Managing Blood Loss in MVT Candidates With PMT.

Transplant Direct 2021 Mar 11;7(3):e670. Epub 2021 Feb 11.

Department of Surgery, Duke University Hospital, Durham, NC.

Explantation of native viscera in multivisceral transplant candidates, particularly in those with extensive portomesenteric thrombosis (PMT), carries considerable morbidity due to extensive vascularized adhesions. Preemptive visceral angioembolization has been previously described as a technique to minimize excessive blood loss during mobilization of the native viscera but is not well described specifically in patients with extensive PMT.

Methods: In a series of 5 patients who underwent mutivisceral transplant for PMT from June 2015 to November 2018, we performed preoperative superior mesenteric, splenic, and hepatic artery embolization to reduce blood loss during explanation and evaluated the blood loss and blood product utilization, as well as 30-day rates of infectious complications.

Risk reduction and pharmacological strategies to prevent progression of aortic aneurysms.

Expert Rev Cardiovasc Ther 2021 Jun 9. Epub 2021 Jun 9.

Aortic Institute at Yale-New Haven Hospital, Yale University School of Medicine, New Haven, CT, USA.

Introduction: While size thresholds exist to determine when aortic aneurysms warrant surgical intervention, there is no consensus on how best to treat this disease before aneurysms reach the threshold for intervention. Since a landmark study in 1994 first suggested ß-blockers may be useful in preventing aortic aneurysm growth, there has been a surge in research investigating different pharmacologic therapies for aortic aneurysms-with very mixed results.

Areas Covered: We have reviewed the existing literature on medical therapies used for thoracic and abdominal aortic aneurysms in humans. Read More

Department of Cardiothoracic Surgery, General Hospital of Eastern Theater Command, Nanjing 210002, China.

In recent years, the endovascular procedures has considerably evolved in concepts, technologies, materials and devices on cardiovascular surgery, and influenced the development and the future direction of cardiovascular surgery technology. Endovascular aorta repair is well recognized as the optimal therapy for patients presenting with acute or chronic pathology of distal aortic arch, descending aorta and thoraco-abdominal aorta. The use of catheter-based endovascular repair in the ascending aorta pathology including aneurysms, pseudoaneurysms, penetrating aortic ulcers and acute or chronic Stanford type A aortic dissection has been concerned and reported.

An Undiagnosed Case of Chronic Pancreatitis With Multiple Visceral Arteries Pseudoaneurysm.

Cureus 2021 May 1;13(5):e14789. Epub 2021 May 1.

General Medicine, Rehman Medical Institute, Peshawar, PAK.

Visceral artery aneurysms, which could be either true or pseudo, are abnormal focal dilations of vessels supplying the abdominal organs. True aneurysms, by definition, suggest dilation of the vessel in response to increased blood flow, ultimately causing a blood-filled sac to form. Pseudoaneurysm, however, is the pooling of blood in surrounding tissues secondary to trauma or rupture. Read More

Immediate outcome of endovascular treatment of ruptured juxtarenal aneurysm with parallel stents.

J Vasc Bras 2021 Mar 15;20:e20200120. Epub 2021 Mar 15.

Fundação Bahiana de Cardiologia - FBC, Salvador, BA, Brasil.

Rupture of an abdominal aortic aneurysm is an event with a high mortality rate and treatment is a medical emergency. Endovascular treatment of these aneurysms has become established as a minimally invasive alternative to classical open surgery and is now the first-choice option. However, 20 to 50% of patients with abdominal aortic aneurysms do not have anatomy favorable for endovascular treatment because of a short aneurysm neck or because visceral branches are involved by the aneurysm.
