Aberrant right subclavian arteries were experienced in two young children. This is a rare aortic arch anomaly that usually does not produce symptoms. Symtomatic patients require surgical interventions.We describe two young children who had aberrant right subclavian artery with symptoms of difficulty in swallowing and respiratory problems. Diagnosis was made by esophagography, aortography and 3-Dimension chest CT. Operation had been advocated through right thoracotomy without difficulty for ligation, division and anastomosis to the ascending aorta. Dysphagia lusoria was immediately relieved and postoperative course was uneventful. We consider that the right thoracotomy is the choice of operative approach and noninvasive diagnosis by 3-Dimension chest CT is easily made for infant with aberrant right subclavian artery.

We performed a hybrid procedure for a 58-year-old man with coronary artery disease and a left subclavian artery stenosis. He underwent left subclavian artery stenting and off-pump coronary artery bypass surgery, including grafting the in situ left internal mammary artery to the left anterior descending coronary artery. The post-operative coronary angiogram and computed tomography showed good patency of the graft and stent. He discharged at postoperative 8 days and he has been followed up for six month with an excellent clinical condition.

Central venous catheterization through a subclavian approach is indicated for some special purposes but it may cause many complications such as infection, bleeding, pneumothorax, thrombosis, air embolization, arrhythmia, myocardial perforation, and nerve injury. A case involving a mistaken central venous catheterization into the right vertebral artery through the subclavian artery is presented. A 33-year-old man who had deteriorated mentality after head injury underwent an emergency craniotomy for acute epidural hematomas on the right frontal and temporal convexities. His mentality improved rapidly, but he complained of continuous severe pain in the right posterior neck even though he had no previous symptom or past medical history of such pain. Three-dimensional cervical spine computed tomography (3D-CT) was performed first to rule out unconfirmed cervical injuries and it revealed a linear radiopaque material intrathoracically from the level of the 1st rib up to the level of C6 in the right vertebral foramen. An additional neck CT was performed, and the subclavian catheter was indwelling in the right vertebral artery through right subclavian artery. For the purpose of proper fluid infusion and central venous pressure monitoring, the subclavian vein catheterization had been performed in the operation room after general anesthesia induction before the craniotomy. Sufficient anatomical consideration and prudence is essential because inadvertent arterial cannulation at a non-compressible site is a highly risky iatrogenic complication of central venous line placement.

Subclavian artery aneurysms are quite rare and they are known to be as only 1% of all peripheral aneurysms. Atherosclerotic disease is the most common cause of subclavian artery aneurysms. These aneurysms can cause rupture, thrombosis, embolisms or symptoms by local compression. Surgical operations are generally performed as treatment. We report here on a case of successful surgical treatment for a right proximal subcalvian artery aneurysm, and the surgery was peformed via the medical exclusion method.

A 30-year-old male with a symptomatic aberrant right subclavian artery underwent surgical intervention on January 17, 1990. An aberrant right subclavian artery is a rare congenital anomaly, but it is the most common one of the aortic arch anomalies. This anomalous vessel usually does not produce symptoms, but occasionally symptomatic patients require surgical intervention. Although ligation and division of the aberrant right subclavian artery through left thoracotomy has been advocated by many surgeons, the ischemic symptoms of the upper extremity or the brain can occur. In the procedure described here, ligation and division of the aberrant artery and its anastomosis to the ascending aorta with Gore \ulcornerTex vascular graft was performed simultaneously through midsternotomy. With this procedure, we relieved the esophageal obstruction and established normal blood flow to the right arm. Hoarseness developed postoperatively. We consider that above symptom has been attributed to the injury of the left recurrent laryngeal nerve during dissection.

This case report concerns a young patient with an extremely rare combination of d-transposition of the great arteries (d-TGA) and anomalous origin of the right subclavian artery. In our patient, the right subclavian artery originated from the pulmonary artery, which is why he did not show reversed differential cyanosis. We conclude that the presence of an aortic arch anomaly should be considered in patients with d-TGA who do not present with reversed differential cyanosis. A further imaging work-up, including computed tomography or magnetic resonance imaging, might be helpful.

Subclavian steal syndrome is a type of obstructive artery disease caused by severe stenosis and occlusion of a left proximal subclavian artery or brachiocephalic trunk. The resulting vertebro-basilar insufficiency symptoms are due to retrograde blood flow from the contralateral vertebral and basilar arteries into the low-pressure ipsilateral upper extremity vessels. For that reason, patients usually experience dizziness or arm ischemic symptoms. Neurointervention is an effective treatment for ischemic stroke, including the subclavian artery stenosis. This paper reports a patient with subclavian steal syndrome who had a vertebral artery Doppler waveform change in duplex sonography and a 12 mmHg difference in interarm systolic blood pressure. A stenotic lesion of the subclavian artery was treated effectively by inserting a precise stent. The follow up examination showed that the vertebral artery Doppler waveform change disappeared and recovered and that the 12 mmHg difference in interarm systolic blood pressure decreased to 5 mmHg after treatment.

Recently we experienced a case of Takayasu`s arteritis involving the major aortic branches. A 30 year-old female patient admitted with the complaints of dizziness, visual disturbance, headache and tingling sensation of upper extremities. Aortogram revealed nearly complete obstruction of the origin site of both common carotid arteries and right vertebral artery, and irregular luminal narrowing of the origin site of innominate artery and left subclavian artery, but opacification of right subclavian artery and left vertebral artery. Successful surgical treatment was accomplished with a bypass from the ascending aorta to the left common carotid artery using a tube graft. The left subclavian artery and right axillary artery were revascularized distal to the stenosis with tube grafts that extended from the aortic graft. Postoperative complications were atelectasis, lymph leakage and left phrenic nerve palsy. She discharged uneventually at postoperative 22 days and most of symptoms were relieved.

The case of a 40-year-old male with symptom related to a anomalous right subclavian artery [dysphagia lusorium] combined with thymoma is described. He was treated by removal of the thymoma and resection of the retroesophageal right subclavian artery with anastomosis of its distal end to the ascending aortic arch by Gore-Tex. This procedure relieved the dysphagia and provided the right arm with normal arterial circulation.

To demonstrate the 3D usefulness of MDCT, a 73-year-old male patient with subclavian thrombosis was obtained 3D images of maximum intensity projection (MIP), volume rendering, and multiplanar reformation (MPR) to clearly detect and locate the subclavian artery. The data will be provided to the patient for diagnosis and treatment. The scan data were acquired as 3D CT images MIP, volume rendering, curved MPR, and virtual endoscopy images. In the 3D program, the ascending aorta was measured as 364.28 HU, the left carotid artery was 413.77 HU, and the left subclavian artery was 15.72 HU. MIP coronal image shows the closure of the subclavian artery in the left side. Three-dimensional volume images were obtained with 100% permeability and 87-1265 HU. The coronal curved MPR and sagittal curved MPR images show the closure of the subclavian artery due to thrombus using 3D image processing. In the case of subclavian arterial occlusion due to thrombosis, the patient is scanned with MDCT and 3D image processing can be used to confirm occlusion of subclavian artery.
