Three-dimensional CT imaging of aneurysm of aberrant right subclavian artery

We report a case of an aneurysm originating from an aberrant right subclavian artery, which was incidentally found as a compression deformity of the upper esophagus on a barium study in a 46-year-old man. Computed tomography (CT) clearly demonstrated the aneurysm of the aberrant right subclavian artery. In particular, reconstructed three-dimensional CT (3D-CT) was valuable in evaluating the positional relationships between the anomalous vessel with aneurysm and other structures.     

MR imaging of aneurysm of an aberrant right subclavian artery

Magnetic resonance (MR) imaging was performed for evaluation of a right paramediastinal mass in an asymptomatic 84-year-old woman. An aneurysm of an aberrant right subclavian artery was diagnosed. This rare complication of a common congenital anomaly and the use of MR in evaluation is discussed.     

Treatment of aberrant right subclavian artery aneurysm with endovascular exclusion and adjunctive surgical bypass

Aberrant right subclavian arteries occur in as much as 2% of the population. Aneurysms in this vessel are rare but exhibit a marked propensity toward rupture; therefore, early elective treatment is indicated. Transluminally placed stent-grafts offer an alternative approach to the standard surgical treatment. This type of procedure is less invasive, with less attendant risk than operative repair. Because there was no proximal neck between the aneurysm and Kommerell diverticulum in the case described herein, it was decided to perform endovascular exclusion of the aneurysm by inserting an endoprosthesis to occlude the aortic exit of the aneurysm, combined with distal ligation. A bilateral carotid/subclavian bypass was also created to preserve the function of both subclavian arteries.     

Non-invasive imaging of aberrant right subclavian artery pathologies and aberrant right vertebral artery

Here, we review the CT and MR angiography findings of aberrant right subclavian and right vertebral arteries, with emphasis on the differences between these structures. In addition, non-invasive imaging findings of aberrant right subclavian artery pathologies, including arteritis, aneurysm and dissection, are discussed.     

经导管闭合房间隔缺损的疗效观察

目的　评价经导管置入Amplatzer封堵器治疗继发孔型心房间隔缺损 (ASD)的疗效。方法　 11例患者中男 3例 ,女 8例 ,年龄 4～ 46岁 (平均 2 5岁 )。术前经多普勒超声心动图检查房间隔缺损直径为 12～ 2 8mm ,平均 (18.5± 6 .1)mm。在透视及经超声心动图引导下经导管置入Amplatzer封堵器闭合ASD。结果　 11例ASD直径的球囊测量值为 (2 5 .2± 8.3)mm(15～ 36mm) ,选择的封堵器直径为 (2 5 .4± 7.7)mm(15～ 36mm)。 11例封堵器置入均获得成功 ,术中无并发症。 2例术后即刻超声检查显示微量残余分流。术后 1周复查均无分流。结论　经导管置入Amplatzer封堵器治疗ASD是一种有效的非手术方法。     

Inferior thyroid artery arising from common carotid artery with aberrant right subclavian artery

We describe an unusual variant in the blood supply to the inferior portion of the right thyroid gland encountered during parathyroid localization studies. A brief review of other possible variants is given.     

合并迷走右锁骨下动脉的主动脉夹层4例报告并文献复习

目的 分析合并迷走右锁骨下动脉(ARSA)主动脉夹层的临床和影像学特点,总结腔内治疗该病的成功经验.方法 回顾性分析4例合并ARSA的主动脉夹层动脉瘤患者的临床、影像和手术资料.结果 4例合并ARSA的主动脉夹层患者均有后背部撕裂样剧痛,其中1例伴有上腹部疼痛.CT检查发现4例主动脉夹层第一裂口与右迷走右锁骨下动脉关系均较近或位于后者之内,主动脉真腔变窄.根据第一裂口解剖位置的不同分别采取了4种腔内修复治疗方案,手术均获得成功.结论 合并迷走右锁骨下动脉的主动脉夹层临床罕见,其腔内治疗应根据第一裂口的解剖位置进行个性化设计,采用不同的血管腔内治疗方案可提高手术成功率.     

锁骨下动脉瘤的外科治疗

总结5例锁骨下动脉瘤外科治疗经验。认为锁骨下动脉瘤手术方式的选择应以保证生命安全,尽可能恢复正常的血液循环和减少术后并发症为原则,手术在体外循环技术支持下,更安全、更有利于脑组织以及瘤体远端肢体功能的保护。     

MR angiography of left-sided cervical aortic arch with aberrant right subclavian artery

Cervical aortic arch is a rare anomaly. We report the contrast-enhanced MR angiography features of left-sided cervical aortic arch with contralateral descending aorta and aberrant right subclavian artery in a 16-year-old girl.     

Aneurysm of an aberrant right subclavian artery—Computed tomography

An aneurysm of an aberrant right subclavian artery was diagnosed with computed tomography (CT) in a 77-year-old man with an asymptomatic mediastinal mass at admission. Although CT clearly demonstrated this rare congenital anomaly, further radiologic study or surgery was not attempted because of the patient's advanced age and lack of symptoms.     

MDCT evaluation after closure of atrial septal defect with an Amplatzer septal occluder

OBJECTIVE: The essay describes the protocol for and interpretation of MDCT scans in the evaluation of patients after insertion of an Amplatzer septal occluder. CONCLUSION: In anatomic regions that cannot be confidently evaluated with transthoracic echocardiography, MDCT is useful for evaluating Amplatzer septal occluders for protrusion, migration, and residual shunt. Radiologists should be familiar with the imaging protocol and interpretation.
