Outcome of Open Repair of Thoracoabdominal Aortic Aneurysm in Takayasu Arteritis: A Retrospective Analysis.

Background: Takayasu Arteritis (TA) is an immune mediated arteritis causing inflammation of the aorta and its branches, which can result in aortic aneurysms. Our aim is to describe the outcome of surgical management in these patients who presented with Thoracoabdominal aortic aneurysm (TAAA).

Methods: Between 2003 and 2023, 40 TA patients with TAAA underwent operative repair.

Position statement from the Indian Society of Gastroenterology, Cardiological Society of India, Indian Academy of Neurology and Vascular Society of India on gastrointestinal bleeding and endoscopic procedures in patients on antiplatelet and/or anticoagulant therapy.

Antiplatelet and/or anticoagulant agents (collectively known as antithrombotic agents) are used to reduce the risk of thromboembolic events in patients with conditions such as atrial fibrillation, acute coronary syndrome, recurrent stroke prevention, deep vein thrombosis, hypercoagulable states and endoprostheses. Antithrombotic-associated gastrointestinal (GI) bleeding is an increasing burden due to the growing population of advanced age with multiple comorbidities and the expanding indications for the use of antiplatelet agents and anticoagulants. GI bleeding in antithrombotic users is associated with an increase in short-term and long-term mortality.

Carotid Endarterectomy for Symptomatic Carotid Stenosis: Differences in Patient Profile in a Low-Middle-Income Country.

Introduction: Carotid endarterectomy (CEA) is the standard treatment for patients with symptomatic carotid stenosis. Data from low- and middle-income countries are sparse on CEA and its outcomes. We aimed to describe the profile of our patients and factors associated with periprocedural cerebral ischemic events in patients with symptomatic carotid stenosis who underwent CEA in our institute.

Determinants of Suboptimal Outcome Following Thymectomy in Myasthenia Gravis.

Background: Response to thymectomy in myasthenia gravis (MG) is influenced by various patient-, disease-, and therapy-related factors.

Methods: Retrospective analysis of 128 patients with MG who underwent maximal thymectomy over 15 years was done to identify the determinants of suboptimal clinical outcome.

Results: Among the 128 patients, 62 (48.

Brucella-Induced Ruptured Infrarenal Dissecting Abdominal Aortic Aneurysm.

Mycotic aneurysms, often saccular, accounting for approximately 2.5% of all abdominal aortic aneurysms, possess increased risk of rupture, uncontrolled sepsis, and protracted hospital stay and are associated with high morbidity and mortality. The authors report the case of a 49-year-old female with no known comorbidities who presented with free rupture of an infrarenal dissecting mycotic aneurysm and underwent emergent open repair successfully.

Preclinical evaluation of hydrogel sealed fluropassivated indigenous vascular prosthesis.

Background & Objectives: Polyethylene terephthalate (PET) graft, designed and developed at our institute for vascular reconstruction, is porous to promote optimal incorporation and neointima formation, requiring pre-clotting or biomodification by sealing the pores before implantation. The objective of this study was to characterize, test and perform preclinical evaluation of hydrogel (alginate dialdehyde cross-linked gelatin) sealed fluoropassivated PET vascular prosthesis in pig model, so as to avoid pre-clotting, for its safety and efficacy before employing the indigenous and less expensive graft for clinical use.

Methods: Hydrogel sealed, fluoropassivated PET vascular prosthesis were tested for haemocompatibility and toxicity followed by small animal toxicology tests and in vivo experiments in pigs receiving implantation at thoracic aorta.

Criteria for Postoperative Mechanical Ventilation After Thymectomy in Patients With Myasthenia Gravis: A Retrospective Analysis.

Objective: To determine the criteria for postoperative mechanical ventilation after thymectomy in patients with Myasthenia Gravis.

Design: Retrospective study.

Setting: Teritiary care centre.

Effectiveness of ventilation of nondependent lung for a brief period in improving arterial oxygenation during one-lung ventilation: A prospective study.

Background: Hypoxemia is common during one-lung ventilation(OLV), predominantly due to transpulmonary shunt. None of the strategies tried showed consistent results. We evaluated the effectiveness of ventilating the operated, non-dependent lung (NDL) with small tidal volumes in improving the oxygenation during OLV.

The making of indigenous vascular prosthesis.

Background & Objectives: Vascular illnesses are on the rise in India, due to increase in lifestyle diseases and demographic transition, requiring intervention to save life, organ or limbs using vascular prosthesis. The aim of this study was to develop indigenous large diameter vascular graft for treatment of patients with vascular pathologies.

Methods: The South India Textile Research Association, at Coimbatore, Tamil Nadu, India, developed seamless woven polyester (Polyethylene terephthalate) graft at its research wing.

Synchronous hybrid repair for ruptured aneurysm of bovine aortic arch.

Rupture of an aortic arch aneurysm is a life-threatening emergency with the risk of mortality escalating by the hour. We describe the successful hybrid repair of a ruptured bovine aortic arch aneurysm in a 75-year-old man, which involved aortic arch debranching by ascending aorta-bicarotid bypass followed by relining of the aortic lumen with a stent-graft. The procedure was not only lifesaving but also resulted in an active gentleman at 2-year follow-up.

Hybrid Strategy for Residual Arch and Thoracic Aortic Dissection following Acute Type A Aortic Dissection Repair.

Progressive dilatation of the false lumen in the arch and descending aorta has been encountered in one-third of survivors as a late sequelae following repair of ascending aortic dissection. Conventional treatment for the same requiring cardiopulmonary bypass and deep hypothermic circulatory arrest is associated with high morbidity and mortality especially in the elderly cohort of patients. Herein we report a case of symptomatic progressive aneurysmal dilatation of residual arch and descending thoracic aortic dissection following repair of type A aortic dissection, successfully treated by total arch debranching and ascending aortic prosthesis to bicarotid and left subclavian bypass followed by staged retrograde aortic stent-graft deployment.

Chronic mesenteric ischemia and therapeutic paradigm of mesenteric revascularization.

Chronic mesenteric ischemia is a life-threatening clinical problem resulting in death from inanition and/or bowel infarction, if left untreated, albeit low disease prevalence. Typical presentation is postprandial abdominal pain, severe weight loss, and altered bowel habit. Surgical revascularization of the superior mesenteric artery provides effective long-term treatment for chronic intestinal ischemia.

Intact giant abdominal aortic aneurysm due to Takayasu arteritis.

A 35-year-old male fisherman was admitted with complaints of increasing back pain and abdominal discomfort of 1-year duration. Physical examination revealed a prominently visible, expansile, pulsatile, well-defined, nontender abdominal mass in the epigastric, umbilical and both lumbar areas. Computed tomographic (CT) angiography revealed a large juxtarenal aortic aneurysm with a maximum transverse diameter of 14.
