Successful video-assisted thoracoscopic surgery in prone position in patients with esophageal cancer and aberrant right subclavian artery: report of three cases.

ABSTRACT: An aberrant right subclavian artery (ARSA) with an associated nonrecurrent right inferior laryngeal nerve (NRILN) is a relatively rare anomaly that occurs at a frequency of 0.3 to 2.0% of the general population. NRILN has been mainly documented in the head and neck region; it has been rarely described in patients with esophageal cancer, especially those undergoing thoracoscopic surgery. Video-assisted thoracoscopic surgery for esophageal cancer (VATS-E) is becoming more widespread as a reliable minimally invasive surgical procedure associated with reduced perioperative complications.Herein, we report three cases of esophageal cancer with ARSA and NRILN which underwent successful VATS-E. Case 1, a 53-year-old male who had early stage esophageal cancer was performed VATS-E. Upper gastrointestinal (GI) series showed "Bayonet sign" (T1aN0M0, pStageIA in UICC). Case 2, a 75-year-old male who had advanced esophageal cancer was performed neoadjuvant chemotherapy and following VATS-E. This case had right thoracic duct and "Bayonet sign" on upper GI series (T1bN2M0, pStage IIIA in UICC). Case3, a 72-year-old male who had advanced esophageal cancer was performed neoadjuvant chemotherapy and following VATS-E (T3N2M0, pStageIIIB in UICC). All of these three cases were performed VATS-E and discharged without any complication.VATS-E in the prone position is a feasible procedure that can reduce the risk of complications with an enlarged and clear view, and knowledge of this type of anomaly is very important for surgeons who perform esophagectomy.

Thoracoscopic esophagectomy in the prone position for esophageal cancer patients with pectus excavatum: a report of two cases.

Project description:BackgroundPectus excavatum is a common thoracic deformity that can be encountered during thoracoscopic esophagectomy. Here, we report two cases of esophageal cancer complicated by pectus excavatum that were treated with thoracoscopic esophagectomy with the patients in the prone position.Case presentationThe first patient was a 64-year-old male diagnosed with esophageal cancer (cT3N0M0, Haller index 8.5) and underwent radical thoracoscopic esophagectomy in the prone position following neoadjuvant chemotherapy. The second patient was a 67-year-old male diagnosed with esophageal cancer (cT1bN0M0, Haller index 4.3), and the same procedure was performed in this patient. In cases of patients with a high Haller index, where securing the surgical field is difficult, preoperative computed tomography in the prone position can help surgeons to understand the mediastinal field of view and is safe.ConclusionsRadical thoracoscopic esophagectomy in the prone position may be a surgical option in patients with pectus excavatum.

Down syndrome and aberrant right subclavian artery.

Project description:Down syndrome (DS) may be associated with various organ system disorders. Feeding problems are frequent in children with DS and may be caused by associated defects, including congenital heart defects, gastrointestinal defects, or endocrine disorders. In the absence of these associated conditions, feeding problems are often attributed to general hypotonia. However, an aberrant right subclavian artery (ARSA), a rare vascular anomaly and an unusual cause of problems with the passage of solid food through the esophagus, has recently been suggested to occur more frequently in patients with DS. This knowledge is of importance when evaluating feeding difficulties in patients with DS. Additional investigation for identifying an ARSA may be indicated in selected patients. Diagnostic techniques, such as transthoracic echocardiography, barium contrast esophagram, angiography, or computed tomography-angiography (CT) can be used in a diagnostic flow chart. The presence of ARSA is not synonymous to the cause of feeding problems in patients with DS and corrective surgery of this vascular anomaly should be restricted to selected cases.

Successful thoracoscopic management of iatrogenic left subclavian arterial injury: a case report.

Project description:The subclavian artery at the thoracic outlet is in the deepest position of the thoracic cavity and is difficult to repair in this narrow space once injured, even if the surgery is converted to a thoracotomy. This article presents a successful left subclavian artery repair procedure at the thoracic outlet using a thoracoscopic approach, with a video demonstration, and describes its technical characteristics. The patient was planned for a left upper lobectomy through three-port thoracoscopic approach. Severe adhesions were found intraoperatively and an accidental left subclavian arterial injury occurred when dissecting the adhesions. We first clamped the proximal portion of the subclavian artery and then directly clamped the rupture site. Our first suture failed due to the limited suture angle and the mutual restriction between the needle holder and atraumatic vascular clamp. To freely control the needle holder, another assistant port was made in the seventh intercostal space (ICS). The arterial injury was finally successfully repaired using pledgetted suture. The operation time was 235 minutes and intraoperative blood loss was 800 mL. The pulsation of the left radial artery was normal postoperatively, and the patient was discharged on postoperative day 6. Appropriate strategies allow attempts to manage intraoperative hyperbaric arterial bleeding from the systemic circulation, such as bleeding caused by subclavian arterial injuries, by means of a thoracoscopic approach without conversion to thoracotomy.

Successful treatment of patent ductus arteriosus accompanying right-sided aortic arch and aberrant left subclavian artery: a case report.

Project description:BackgroundThe coexistence of a right-sided aortic arch (RAA), an aberrant left subclavian artery (ALSA), and a patent ductus arteriosus (PDA) is a rarely seen vascular ring anomaly. There is currently no general guideline consensus on the management and follow-up of this congenital defect, posing a challenge to the clinicians. At this point, the heart team plays a critical role in the management of the disease.Case summaryIn the present case, a 25-year-old male patient was presented to the outpatient clinic with dyspnoea and fatigue. A transthoracic echocardiography revealed PDA with a left-to-right shunt. To evaluate the anatomy thoroughly, a thoracic computed tomographic angiography was performed and showed PDA accompanying ALSA and RAA. The patient was evaluated by the Heart Team, and a percutaneous closure of PDA was recommended due to signs of left ventricular volume overload. The closure was successfully performed with Amplatzer vascular plug II. At follow-up, the patient was free of symptoms.DiscussionClinicians should be aware of the potential concomitant lesions during the diagnostic work-up. In selected patients, percutaneous closure of PDA may be the first-line therapy in experienced centres.

Anatomic Investigation of Two Cases of Aberrant Right Subclavian Artery Syndrome, Including the Effects on External Vascular Dimensions.

Project description:The retroesophageal aberrant right subclavian artery (ARSA) is a variation of the aortic arch that occurs asymptomatically in most patients. However, when symptomatic, it is most commonly associated with dysphagia. ARSA has also been noted as a location of potentially severe aneurysms in some patients, as well as posing a risk during surgical interventions in the esophageal region. This case study analyzes two individuals with ARSA morphology in comparison to a normal sample in order to gain a better anatomical understanding of this anomaly, potentially leading to better risk assessment of ARSA patients going forward. The diameter of the ARSA vessel was found to be substantially larger than both the right subclavian artery and brachiocephalic trunk of the subjects with classic aortic arch anatomy. As many ARSA individuals are asymptomatic, we hypothesize that the relative size of the ARSA may dictate its contribution to the presence and/or severity of associated symptomatology.

Technical considerations in robotic aberrant right subclavian artery resection for dysphagia lusoria.

Project description:Dysphagia lusoria occurs due to compression of the esophagus as an aberrant right subclavian artery (ARSA) crosses the mediastinum. Surgical management includes open, hybrid, and endovascular techniques, with no consensus gold standard. There are few reports of robotic-assisted ARSA resection. We describe the innovative technique and outcomes for two patients who successfully underwent robotic-assisted transthoracic resection of an ARSA after right carotid-subclavian bypass for dysphagia lusoria. Both patients experienced improvement or resolution of their dysphagia and no major complications. In select patients with a noncalcified origin of the ARSA without aneurysmal degeneration, the robotic-assisted approach represents a viable option.

Hypertrophic Osteopathy Concurrent with an Aberrant Right Subclavian Artery in a Dog.

Project description:A 13-year-old spayed female cocker spaniel was presented with a 2-month history of swelling in several digits and intermittent hindlimb lameness. Radiographs revealed marked soft-tissue swelling and periosteal new bone formation without cortical bone destruction, characteristic of hypertrophic osteopathy (HO), in the distal parts of all extremities except for the right forelimb. However, no notable findings were detected in thoracic radiographs. An ultrasonography indicated cranial bladder wall thickening, which resolved following antibiotic therapy. Computed tomographic angiography identified a potential underlying cause as an aberrant right subclavian artery (ARSA) originating from the aortic arch, compressing the esophagus and causing mild esophageal cranial dilation to the aberrant vessel. No other intrathoracic or neoplastic lesions were observed. Gastrointestinal symptoms, such as regurgitation, were absent. Although an ARSA was likely the cause of HO, surgical correction was declined by the owner. To the best of our knowledge, this is the first reported case of HO concurrent with ARSA in dogs.

Right Aortic Arch and Kommerell's Diverticulum Repaired without Reconstruction of Aberrant Left Subclavian Artery.

Project description:Right aortic arch with Kommerell's diverticulum is a very rare situation. Surgical treatment is recommended for symptomatic patients or asymptomatic patients with a large diverticulum. However planning the strategy of operation is difficult without a 3D imaging. We report a case of a 57-year-old man with right aortic arch, Kommerell's diverticulum, and aberrant left subclavian artery. After a 3D-CT imaging, the patient underwent descending aortic replacement without reconstruction of aberrant left subclavian artery. After operation, there was no signs or symptoms of ischemia of the left arm. If the reconstruction of the aberrant subclavian artery was too difficult, closing its orifice is an acceptable decision. It has been found advantageous because of a decrease blood loss and a shorter cardiopulmonary bypass duration. If an ischemia of the arm is noticed, additional reconstruction will have to be considered. 3D-CT imaging was very useful to have a proper orientation and plan for the operative strategy.

The "No ARSA" Sign: A Novel Method of Prenatal Screening for Aberrant Right Subclavian Artery.

Project description:An aberrant right subclavian artery (ARSA) can be overlooked by the conventional method as described by Chaoui et al., due to acoustic shadowing. The aim of this study was to evaluate the feasibility and accuracy of a novel screening method for ARSA by demonstrating the brachiocephalic artery bifurcation, referred to as the "No ARSA" sign. A prospective study conducted at a tertiary care center between 2018 and 2019 included unselected pregnant patients at a median gestational age of 15.1 (14.2-22.1; IQR (inter-quartile range)) weeks, who had been referred for a routine or targeted anomaly scan. All participants were scanned for the presence or absence of ARSA using both the conventional and the novel "No ARSA" methods for validation purposes. A total of 226 unselected patients were enrolled in the study. The "No ARSA" sign was visualized in 218 fetuses (96.5%). In the remaining 8 cases (3.5%), the "No ARSA" sign was not demonstrated. In these fetuses, an ARSA was visualized by the conventional method. The new method exhibited 100% feasibility and was in complete agreement with the conventional method. Intra- and inter-observer agreement was excellent (? = 1). The results of the study suggest that the "No ARSA" sign is an efficient and reliable screening tool for ARSA.

Non-recurrent laryngeal nerve injury associated with an aberrant right subclavian artery: a case report.

Project description:BackgroundInjury to the recurrent laryngeal nerve (RLN) is a recognised complication of surgery in the neck. The presence of a non-recurrent laryngeal nerve (NRLN) significantly increases the risks of a nerve injury. Given that NRLNs are strongly associated with vascular abnormalities that can be visualised on preoperative imaging, we describe a case to raise awareness of this association with the aim of reducing the risk of iatrogenic nerve injury.Case descriptionA 61-year-old gentleman was referred by his family doctor with a history of radiating left arm pain and paraesthesia consistent with C6 +/- C7 radiculopathy. The patient failed conservative management, and elected to undergo an anterior cervical discectomy and fusion procedure. Preoperative magnetic resonance imaging (MRI) showed an incidental finding of an aberrant right subclavian artery (ARSA) following a retro-oesophageal path. Surgery was performed with a right sided cervical approach without intraoperative complications; however, the patient had marked dysphonia post-operatively. Assessment by otorhinolaryngology (ORL) concluded that this was most likely secondary to a right NRLN palsy. The patient underwent a vocal fold injection laryngoplasty for temporary vocal fold augmentation, and the voice subsequently recovered and remained asymptomatic at 1-year post-procedure.ConclusionsThis case demonstrated that identification of vascular anomalies associated with NRLNs on preoperative imaging should prompt a left sided cervical approach to avoid a nerve injury during surgery.
