RESUMO
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. RESULTS: There were 24 females and 16 males, in the age group of 19-53 years, with hypertension in 20 patients. Raised Erythrocyte sedimentation Rate was present in 13 patients. According to Crawford classification, there were 2 patients with type I, 2 with type II, 17 with type III, 12 patients with type IV and 7 with type V aneurysm. Multiple steno-occlusive lesions of aortic branches were present in 21 patients, with majority affecting the renal artery. Femoral Artery Femoral Vein Partial cardiopulmonary bypass was used for types I, II, III and V. Separate bypass to visceral branches was done in eight patients, of whom five had multiple bypasses and three patients only had renal bypass. Twelve patients underwent reimplantation of branches, out of which nine had multiple vessel reimplantation. Four patients underwent staged repair of the aneurysm, which included visceral debranching in the first day, followed by repair of the aneurysm in the next day. In the immediate postoperative period, ten patients developed acute kidney injury and two required dialysis. Other morbidities included acute respiratory distress syndrome (ARDS), spinal cord dysfunction, bleeding, and wound complications. Three patients expired in the immediate postoperative period. Mean duration of intensive care unit stay was 4.1 days and hospital stay was 12.7 days. Comparison of disease activity with morbidity and mortality was statistically insignificant. Patients were on follow-up for a range of 6 months to 14 years and median follow-up of 25 months. Over this time period four patients expired and four developed anastomotic pseudoaneurysm requiring intervention. On comparing the disease activity at the time of surgery with the long-term arteritis related complications that required intervention, the P value was 0.653 and hence statistically not significant. The 10-year survival rate is 84.4%. CONCLUSIONS: Surgical repair has good and satisfactory outcome, with low early and late mortality rates. Progression of disease can occur at any stage of the disease, hence indicating the need for long term follow-up and frequent imaging.

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. In addition, in recent decades, there has been an exponential increase in the use of diagnostic and therapeutic GI endoscopic procedures. Since endoscopic procedures hold an inherent risk of bleeding that depends on the type of endoscopy and patients' comorbidities, in patients already on antithrombotic therapies, the risk of procedure-related bleeding is further increased. Interrupting or modifying doses of these agents prior to any invasive procedures put these patients at increased risk of thromboembolic events. Although many international GI societies have published guidelines for the management of antithrombotic agents during an event of GI bleeding and during urgent and elective endoscopic procedures, no Indian guidelines exist that cater to Indian gastroenterologists and their patients. In this regard, the Indian Society of Gastroenterology (ISG), in association with the Cardiological Society of India (CSI), Indian Academy of Neurology (IAN) and Vascular Society of India (VSI), have developed a "Guidance Document" for the management of antithrombotic agents during an event of GI bleeding and during urgent and elective endoscopic procedures.

INTRODUCTION: Carotid Endarterectomy (CEA) is the standard treatment for patients with symptomatic carotid stenosis. Data from Low- and Middle-Income Countries (LMIC) is 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. METHODS: Retrospective review of patients with symptomatic carotid stenosis(50-99%) who underwent CEA between January 2011 and December 2021 was done. Clinical and imaging parameters and their influence on periprocedural cerebral ischemic events were analysed. RESULTS: Of the 319 patients (77% males) with a mean age of 64 years (SD ±8.6), 207 (65%) presented only after a stroke. Majority (85%) had high grade stenosis (ï³70%) of the symptomatic carotid. The mean time to CEA was 50 days (SD ±36), however only 26 patients (8.2%) underwent surgery within 2 weeks. Minor strokes and TIA occurred in 2.2%, while major strokes and death occurred in 4.1% patients. None of the clinical or imaging parameters predicted the periprocedural cerebral ischemic events. The presence of co-existing significant (ï³50%) tandem intracranial atherosclerosis (n=77, 24%) or contralateral occlusion (n=24, 7.5%) did not influence the periprocedural stroke risk. CONCLUSION: There is a delay in patients undergoing CEA for symptomatic carotid stenosis. Majority have high grade stenosis and present late only after a stroke reflecting a lack of awareness. CEA can be performed safely even in patients with significant intracranial tandem stenosis and contralateral carotid occlusion.
RESUMO
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. Considering the morbidity and mortality of open surgery using circulatory arrest, state-of-the-art synchronous hybrid repair seems to be an effective alternative for ruptured aortic arch aneurysms.

Sporadic reports on cardiac herniation are available in the literature; most of them had followed intrapericardial pneumonectomies for malignant pulmonary tumors. We present an uncommon event of heart herniation after a completion pneumonectomy indicated for chronic bronchiectasis. A 35-year-old male patient was operated for left completion pneumonectomy. A 6 cm x 4 cm area of adherent pericardium near the obtuse margin of heart was removed during surgery. During head-end elevation of the bed in postoperative intensive care unit, patient got accidentally tilted to the left side, which resulted in ventricular fibrillation. Chest cavity was re-opened for cardiopulmonary resuscitation. Left ventricle was found herniating through the pericardial deficiency into the left-thoracic cavity with the cardiac apex touching chest wall. During surgical re-exploration, the pericardial deficiency was closed with a synthetic Dacron patch. Hemodynamic condition remained stable in the immediate postoperative period. Patients had infection of the left thoracic cavity after 5 weeks, for which he was subjected to thoracoplasty and omentopexy. Prompt recognition with timely intervention is life saving from cardiac herniation. Strategy of closing the pericardial defect after pneumonectomy should be followed routinely, irrespective of the indication for pneumonectomy.

OBJECTIVE: Post-operative ductal aneurysm is a rare but fatal condition. We retrospectively analyzed the clinical profile of post-operative ductal aneurysm and outcome of their repair with different surgical approaches. METHODS: From January 1976 to December 2002, 13 patients underwent repair of post-operative ductal aneurysm. The case data of the patients operated were analyzed and survivors were followed-up. Three patients underwent repair through left thoracotomy, femoro-femoral bypass and 10 patients underwent patch aortoplasty through sternotomy using total circulatory arrest with minimal dissection. Among the sternotomy group, nine patients had midline sternotomy and one patient had transverse sternotomy with the patient in semi-right-lateral position. Hemoptysis (69%) was the commonest presenting symptom. Ten patients had ligation and three patients had division of ductus. Mean age at ductus interruption was 13.7+/-8.2 years; mean time interval for development of aneurysm was 3.6+/-4.2 years; mean age at aneurysm surgery was 16.9+/-8.8 years. Residual left to right shunt was detected in 6 (46%) patients. RESULTS: Three patients repaired through left thoracotomy with femoro-femoral bypass died during surgery due to rupture of aneurysm during dissection and profuse bleeding. Thirty-day survival in patients operated through sternotomy using circulatory arrest was 90% (9/10). Two patients required additional incision in second left intercostal space along with midline sternotomy, for access to descending thoracic aorta. Of these two patients, one patient had bleeding from friable aorta and died; another patient developed left hemiplegia; circulatory arrest time was prolonged in this patient. Mean follow-up period was 9.6+/-5.3 years. Persistent left vocal cord palsy was seen in one patient. One patient was lost to follow-up after 3-years. Remaining eight patients were asymptomatic at follow-up. CONCLUSION: Repair of postoperative ductal aneurysm through left thoracotomy is difficult due to extreme fragility of aneurysm and because of reoperative difficulties. The immediate and long-term outcome of the cases operated through sternotomy using total circulatory arrest with minimal dissection is good. Midline sternotomy limits approach to descending thoracic aorta that can be circumvented by using transverse sternotomy with semi-right-lateral positioning of the patient.
