Background: Kommerell’s diverticulum is a rare vascular anomaly characterized as an outpouch at the onset of an aberrant subclavian artery. In the variant of a right-sided aortic arch, the trachea and esophagus are enclosed dorsally by the arch. In the configuration of an aberrant left subclavian artery, a Kommerell’s diverticulum and persisting ductus arteriosus or ductal ligament enclose the lateral side, forming a vascular ring which may result in (symptomatic) esophageal or tracheal compression. Spontaneous rupture of an aneurysmatic Kommerell’s diverticulum has also been reported. Due to the rarity of this condition and underreporting in the literature, the clinical implications of a Kommerell’s diverticulum are not well defined. Case summary: We describe seven consecutive adult patients with a right-sided aortic arch and an aberrant course of the left subclavian artery (arteria lusoria), and a Kommerell’s diverticulum, diagnosed in our tertiary hospital. One patient had severe symptoms related to the Kommerell’s diverticulum and underwent surgical repair. In total, two of the patients experienced mild non-limiting dyspnea complaints and in four patients the Kommerell’s diverticulum was incidentally documented on a computed tomography (CT) scan acquired for a different indication. The size of the Kommerell’s diverticulum ranged from 19 × 21 mm to 30 × 29 mm. In the six patients that did not undergo surgery, a strategy of periodic follow-up with structural imaging was pursued. No significant growth of the Kommerell’s diverticulum was observed and none of the patients experienced an acute aortic syndrome to date. Discussion: Kommerell’s diverticulum in the setting of a right-sided aortic arch with an aberrant left subclavian artery is frequently associated with tracheal and esophageal compression and this may result in a varying range of symptoms. Guidelines on management of Kommerell’s diverticulum are currently lacking. This case series and literature overview suggests that serial follow-up is warranted in adult patients with a Kommerell’s diverticulum with small dimensions and no symptoms, however, that surgical intervention should be considered when patients become symptomatic or when the diameter exceeds 30 mm in the absence of symptoms.

Double aortic arch (DAA) is a rare disease requiring high index of clinical suspicion for diagnosis. If undiagnosed, it can pose a serious challenge during anesthetic induction because of dynamic nature of tracheal compression. When DAA is associated with other congenital heart diseases, anesthetic management becomes even more challenging. We report the perioperative anesthetic management of a very rare case of DAA associated with pentalogy of Fallot.

Introduction: Benign nodular goiter may be associated with swallowing difficulties, but insight into the associated pathophysiology is limited. The aim of this study was to investigate the effect of surgery on the degree of esophageal compression, and its correlation to swallowing difficulties.Methods: Esophageal compression and deviation were evaluated blindly on magnetic resonance imaging (MRI) of the neck, prior to and 6 months after thyroid surgery for symptomatic benign goiter. Goiter symptoms and swallowing difficulties were measured by the Goiter Symptom Scale of the Thyroid-Specific Patient-Reported Outcome (ThyPRO) questionnaire. Cohen's d was used for evaluating effect sizes (ES). Results: Sixty-four patients completed the study. Before surgery, median goiter volume was 57 (range 14-642) mL. The smallest cross-sectional area of the esophagus (SCAE) increased from a median of 95 (47-147) to 137 (72-286) mm 2 (ES = 1.31, p < 0.001). Median esophagus width increased from 15 (range 10-21) to 17 (range 12-24) mm (ES = 0.94, p < 0.001) after surgery, while no statistically significant change was observed for the sagittal dimension (anterior-to-posterior), thus reflecting an increasingly ellipsoid esophageal shape. Median esophageal deviation decreased moderately after surgery from 4 (0-23) to 3 (0-10) mm (ES = 0.54, p = 0.005). The goiter symptom score improved considerably from (mean ± SD) 40 ± 21 to 10 ± 10 points (ES = 1.5, p < 0.001) after surgery, and the improvements were associated with improvements in SCAE ( p = 0.03). Conclusions: In patients with goiter, thyroidectomy leads to substantial improvements in esophageal anatomy, as assessed by MRI, and this correlates with improved swallowing symptoms. This information is valuable in qualifying the dialogue with goiter patients, before deciding on the mode of therapy. Clinicaltrials.gov (NCT03072654).

Objective: Intrinsic esophageal pathologies constitute prime cause for dysphagia clinically. However, thoracic esophageal domain is prone to extrinsic compression by various vascular afflictions including aneurysms with attendant therapeutic challenges. Herein, we present a case series of dysphagia aortica with emphasis on its appropriate management option based on grade of dysphagia. Methods: Patients who presented to the vascular division of our tertiary care referral institute between January 2014 and October 2015 with dysphagia due to extrinsic esophageal compression by aneurysmal thoracic aorta form the basis for this report. Prior to referral, all patients were evaluated elsewhere to rule out intrinsic causes and computed tomography angiogram performed delineating aortic aneurysm in four patients and penetrating aortic ulcer in one. Patient cohort included one female and four male patients whose age ranged from 40 to 68 years, with a median of 62 years. Left posterolateral thoracotomy provided access to an aneurysm which was repaired using interposition polyester graft in four patients. Due to severe comorbidities which precluded open surgery, one patient who presented with mild dysphagia was managed by endovascular stent graft repair. Results: Degree of dysphagia was assessed between grades 0 and 4 as in literature. All patients, including four open conventional and one endovascular, recovered well and left hospital totally symptom free. Conclusion: Dysphagia due to vascular diseases in the thoracic domain is an uncommon clinical entity. Patients with thoracic aortic aneurysm presenting with severe dysphagia deserve open surgical repair to provide optimal symptomatic relief in addition to saving life. The state-of-the-art endovascular stent grafting may be considered in very elderly patient having severe comorbidities presenting with mild dysphagia.

No abstract available. Article truncated after 150 words. A 78-year-old gentleman presented to the hospital via EMS with altered mental status. An urgent CT of the head performed in the emergency room demonstrated a large, right intraparenchymal hemorrhage with intraventricular extension into the right lateral ventricle. His Glascow Coma Scale score was 6, and he was intubated for airway protection. A chest radiograph performed to verify placement of the endotracheal tube demonstrated prominence of the upper mediastinum in the region of the right paratracheal strip (Figure 1). A CT of the chest (Figure 2) demonstrated a double aortic arch corresponding to the upper mediastinal abnormality noted on the chest radiograph. In speaking with the patient’s family after acquiring the CT of the chest, they stated that the patient had long-term issues with dysphagia – specifically choking with solid foods. Unfortunately, the patient passed away from complications of his large intraparenchymal hemorrhage. A double aortic arch results from persistence of …

Ankylosing spondylitis (AS) is a chronic inflammatory rheumatological disease affecting the axial skeleton with various extra-articular complications. Dysphagia due to a giant anterior osteophyte of the cervical spine in AS is extremely rare. We present a 48-year-old male with AS suffering from progressive dysphagia to soft foods and liquids. Esophagography showed an anterior osteophyte at C5-C6 resulting in esophageal compression. The patient refused surgical resection of the osteophyte and received conservative therapy. However, after 6 months there was no improvement in dysphagia. This case illustrates that a large cervical osteophyte may be the cause of dysphagia in patients with AS and should be included in the diagnostic workup in early stages of the disease.

Dysphagia lusoria (lusus naturae, latin for "freak of nature") describes dysphagia because of vascular compression of the esophagus. Symptoms, when present, occur at the two extremes of life. Owing to the more flexible and compressible nature of the trachea, children usually present with respiratory symptoms, in contrast to adults, who more often present with dysphagia. Here, we report the case of a six-year-old child presenting with a history of progressive dysphagia without respiratory symptoms. A barium esophagogram showed a diagonal impression in the proximal esophagus, while at esophagogastroduodenoscopy there was an extrinsic pulsatile bulging area suggesting an extrinsic compression by an aberrant vessel. Angio-CT (computed tomography) scan confirmed the presence of an aberrant right subclavian artery. info:eu-repo/semantics/publishedVersion
