Abdominal aortic aneurysm with concomitant horseshoe kidney is exceedingly rare. Although open repair was previously the treatment, endovascular aortic repair has become an increasingly popular option. In the current endovascular era, complex aortic pathologies are treatable with selective use of multiple advanced techniques. We present a unique case involving complex endovascular repair of abdominal aortic aneurysm complicated by presence of horseshoe kidney with central renal artery in a patient where an open approach was prohibited., Competing Interests: None., (© 2024 The Author(s).)

Background: Thoracic aortic dissection (TAD) and aneurysm (TAA) are rare but catastrophic. Prompt recognition of TAD/TAA and differentiation from acute coronary syndrome (ACS) is difficult yet crucial. Earlier identification of TAA/TAD based upon routine emergency department screening is necessary., Methods: A retrospective analysis of patients that presented with acute thoracic complaints to the ED from January 2007 through June 2012 was performed. Cases of TAA/TAD were compared to an equal number of controls which consisted of patients with the diagnosis of ACS. Demographics, physical findings, EKG, and the results of laboratory and radiological imaging were compared. P-value of > 0.05 was considered statistically significant., Results: In total, 136 patients were identified with TAA/TAD, 0.36% of patients that presented with chest complaints. Compared to ACS patients, TAA/TAD group was older (68.9 vs. 63.2 years), less likely to be diabetic (13% vs 32%), less likely to complain of chest pain (47% vs 85%) and head and neck pain (4% vs 17%). The pain for the TAA/TAD group was less likely characterized as tight/heavy in nature (5% vs 37%). TAA/TAD patients were also less likely to experience shortness of breath (42% vs. 51%), palpitations (2% vs 9%) and dizziness (2% vs 13%) and had a greater incidence of focal lower extremity neurological deficits (6% vs 1%), bradycardia (15% vs. 5%) and tachypnea (53% vs. 22%). On multivariate analysis, increasing heart rate, chest pain, diabetes, head & neck pain, dizziness, and history of myocardial infarction were independent predictors of ACS., Conclusions: Increasing heart rate, chest pain, diabetes, head & neck pain, dizziness, and history of myocardial infarction can be used to differentiate acute coronary syndromes from thoracic aortic dissections/aneurysms.

Dysphagia lusoria occurs secondary to an aberrant right subclavian artery coursing posterior to the oesophagus. Open ligation and transposition to the right carotid artery via a right supraclavicular approach has been described as a minimally invasive method. However, approaching the origin of the aberrant right subclavian artery through this incision can be extremely challenging. A persistent aberrant right subclavian artery stump may account for postoperative residual dysphagia. This article describes a safe, effective and reproducible surgical approach to dysphagia lusoria due to a non-aneurysmal aberrant right subclavian artery.

Objective: The role of thoracic surgery in patients with acquired immunodeficiency syndrome (AIDS) continues to evolve. This review seeks to evaluate the outcome, morbidity, and mortality associated with video-assisted thoracoscopic surgery for empyema and pneumothorax in patients with AIDS., Methods: A retrospective review was conducted of patients with AIDS in whom video-assisted thoracoscopic surgery was performed for empyema (group 1) or intractable pneumothorax (group 2)., Results: Twenty patients with AIDS (95% male, mean age 37.4 years, mean CD4 count 76 cells/ml3) underwent thoracoscopy. Surgery was performed for empyema (group 1) in 11 (55%) and intractable pneumothorax (group 2) in nine (45%). Three patients (15%) died within 30 days of the operation. At mean follow-up (29 months), overall survival was 55%. For those who survived the hospitalization and died within the follow-up period (35.3%), mean survival time was 8.2 months (range 1 month to 27 months). In group 1, surgical procedures were performed after 8 days of chest tube drainage and included pleural debridement and mechanical pleurodesis (n = 11) along with lung biopsy (n = 6). Survivals at 30 days and 29 months' follow-up were 90.9% and 45.4%, respectively. In group 2, significantly depressed CD4 counts (average 33.2 cells/ml3) were noted along with a more prolonged preoperative hospitalization (18.5 days) with 14.2 days spent with a chest tube before the operation. In this group, operative procedures included mechanical pleurodesis and talc poudrage (n = 9), bleb resection (n = 7), and lung biopsy (n = 1). Two deaths (22%) occurred within 30 days of the operation and survival at 29 months' follow-up was 66%., Conclusion: Video-assisted thoracoscopic surgery performed in patients with AIDS for the treatment of empyema and intractable pneumothorax is effective, can be performed with little operative morbidity and mortality, and is associated with acceptable long-term survival. Video-assisted thoracoscopic surgery is best performed soon after the diagnosis of intractable pneumothorax or empyema has been established.
