Methods: Retrospective study of all patients treated for INAA at a single academic hospital in Santiago, Chile, between 2002 and 2022.

Stenting of innominate vein compression syndrome.

We report the case of a 60-year-old woman who sought medical attention for left cervical and supraclavicular pain and swelling. Previous computed tomography, intravascular ultrasound, and venography studies were reviewed, confirming extrinsic compression of the left innominate vein by the left common carotid artery against the left clavicle head. Stenting of the lesion was performed, with good mid-term symptom relief and patency.

Endovascular treatment of a right pulmonary sequestration supplied by an aneurysmal aberrant artery originating from the abdominal aorta.

Endovascular embolization of arteries feeding pulmonary sequestrations is a growing therapeutic option. A 51-year-old woman with chest pain and hemoptysis was admitted. During hospitalization she presented 150 mL hemoptysis, hypotension, and hematocrit fell to 23.

[Concentrating ruptured abdominal aortic aneurysm surgery in specialized centers].

Ruptured abdominal aortic aneurysm (RAAA) is an arterial emergency with an overall mortality of 80%-90% secondary to massive hemorrhage. If a patient with RAAA presents in a primary hospital without resolution capacity, survival will depend on early transfer to a center with adequately trained specialists. This article reviews the evidence supporting the centralization of AAAR treatment in qualified centers, specifying the criteria used for the selection of referral centers and the role of a coordinating unit.

Acute Symptomatic Free-Floating Thrombus in the Innominate Artery, a Case Series.

Background: Innominate artery embolism may result in upper extremity ischemia or stroke. A free-floating thrombus originating from the IA is an unusual and dangerous disorder with embolic potential. Only isolated cases have been described showing different treatment modalities.

True Idiopathic Brachial Artery Aneurysm Treated With a Saphenous Vein Graft.

The objective of this study is to report a case of a 65-year-old woman who presented with pallor and pain of her left arm secondary to a true arterial brachial aneurysm, which was successfully treated with saphenous vein bypass and embolization of the aneurysm sac. A review of the literature is also presented. A 65-year-old woman presented with an acute onset of pallor and pain of her left forearm, and hand.

Extrinsic venous compression secondary to spine osteophytes.

Objective: This study aims to report two cases of symptomatic extrinsic compression of the inferior vena cava and left iliac vein caused by vertebral osteophytes.

[Rupture of abdominal aortic aneurysm into the duodenum: uncommon cause of massive gastrointestinal bleeding].

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.

Two New Adenosine Derivatives and their Antiproliferative Properties: An Evaluation.

Background: Adenosine is a natural nucleoside present in a variety of organs and tissues, where it acts as a modulator of diverse physiological and pathophysiological processes. These actions are mediated by at least four G protein-coupled receptors, which are widely and differentially expressed in tissues. Interestingly, high concentrations of adenosine have been reported in a variety of tumors.

[Endovascular management of chronic limb ischemia. Experience in 48 procedures].

Background: Chronic limb ischemia can lead to high rates of limb loss and mortality. Open surgery is the gold standard for treatment of distal disease. Endovascular surgery should have less complications with similar outcomes.

A Beginner's Guide to Osmoprotection by Biostimulants.

Water is indispensable for the life of any organism on Earth. Consequently, osmotic stress due to salinity and drought is the greatest threat to crop productivity. Ongoing climate change includes rising temperatures and less precipitation over large areas of the planet.

Endovascular Management of a Ruptured Iliac Aneurysm With an Inferior Vena Cava Fistula.

Aortocaval fistula is uncommon and often associated with a ruptured iliac or abdominal aortic aneurysm. It has a high mortality secondary to the aneurysmal rupture but also to a high output heart failure. Open surgery has been the standard; however, endovascular management has emerged with lower mortality.
