The anomaly which the right pulmonary artery originates from the ascending aorta is a rare and usually fatal form of congenital heart disease. This lesion is often associated with a patent ductus arteriosus. Death frequently occurs in early infancy. Anomalous origin of the right pulmonary artery is much more common than anomalous origin of the left pulmonary artery. The anomalous right pulmonary artery usually arise from the posterior aspect of the ascending aorta close to the aortic valve. We report a 1 month-old infant with right pulmonary artery arising from the ascending aorta, which was corrected successfully by direct anastomosis to the main pul onary artery.

The common carotid artery generally bifurcates into the internal and external carotid arteries at the level of C3-4. Injury to the common carotid artery during anterior cervical discectomy is a complication that is very much feared but encountered rarely. Knowing the anatomic variations of the common carotid artery and using an operating microscope during the anterior cervical approach for cases with low-lying bifurcation of the common carotid artery would prevent injuries to this artery. We present a 42-year-old female who has successfully undergone anterior cervical discectomy at the level of C5-6 and C6-7. She had a low-lying bifurcation of the common carotid artery.

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.

Vertebral artery loop formation causing encroachment on cervical neural foramen and canal is a rare cause of cervical radiculopathy. We report a case of 61-year-old woman with vertebral artery loop formation who presented with right shoulder pain radiating to her arm for 2 years. Plain radiograph and computed tomography scan revealed widening of the right intervertebral foramen at the C5-6 level. Magnetic resonance imaging and angiogram confirmed the vertebral artery loop formation compressing the right C6 nerve root. We had considered microdecompressive surgery, but the patient's symptoms resolved after conservative management. Clinician should keep in mind that vertebral artery loop formation is one of important causes of cervical radiculopathy. Vertebral artery should be visualized using magnetic resonance angiography in suspected case.

Bilateral coronary artery to pulmonary artery fistulas are very rare anomaly. Echocardiography, cardiac catheterization and coronary angiography of two patients having chest pain and dyspnea showed bilateral coronary to pulmonary artery fistulas. One patient had left anterior descending coronary artery stenosis and the other patient had cystic tumor. We report the good results of the surgical treatment of two patients with bilateral coronary to pulmonary artery fistulas.

While popliteal artery aneurysm is the most common form of peripheral artery aneurysm, it is a rare condition in the general population. Furthermore, a giant popliteal artery aneurysm has not previously been reported in Korea. A 67-year-old male presented with left thigh pain that had begun 4 months earlier and was aggravated when in a sitting position. We found a giant aneurysm on the left popliteal artery and performed a bypass from the common femoral artery to the distal popliteal artery below the knee, using the autologous greater saphenous vein, and excluded the aneurysm at the sites of anastomoses.

In the 1970s, the radial artery was proposed as a coronary artery bypass graft but then was abandoned due to graft occlusion secondary to spasm during harvesting. Development of new pharmacologic antispasmodic agents and minimal traumatic harvesting techniques has led to the revival of the use of the radial artery in coronary artery bypass procedures. Harmonic Scalpel(Ultracision Inc, Smithfield, Rl) offers the surgeon the ability to perform less traumatic, spasm free, and rapid radial artery harvesting.

Prior knowledge of arterial supply to the head and neck is of substantial importance for well-planned surgeries involving the concerned region. We are reporting an unusual and rare variation in the branching pattern of external carotid artery in a 60-year-old female cadaver. A common trunk known as thyrolinguofacial trunk, originating from the anterior surface of the external carotid artery (right and left) giving of superior thyroid artery and a linguofacial trunk during a routine neck dissection. The linguofacial trunk then divided into a lingual and a facial artery. Vascular abnormalities are usually detected either on the dissection table or by the radiologists during imaging or accidently during surgeries leading to serious consequences.

A persistent proatlantal artery (PA) is rare. We report a type 1 persistent PA originating from the right external carotid artery (ECA). A 78-year-old woman presented with dizziness. Computed tomographic (CT) angiography showed a persistent PA originating from the right ECA. This persistent PA did not pass through the atlas transverse foramen. The extracranial segment of this artery in the atlas transverse process level had a more lateral position than a normal left vertebral artery. CT angiography well demonstrated the relationship with bony structures and the course of this persistent PA. This anomalous artery in our patient presented as an incidental finding. Surgeon should recognize a persistent PA when performing carotid endarterectomy or ligation of the ECA for avoidance of complication.

Anomalous origin of the coronary artery from the pulmonary artery is a rare and potentially fatal congenital heart defect. Up to 90% of infants with an anomaly involving the left coronary artery die within the first year of life if left untreated. Patients who survive beyond infancy are at risk of sudden cardiac death. Cardiac CT and MRI are increasingly being used for the accurate diagnosis of this anomaly for prompt surgical restoration of the dual coronary artery system. Moreover, life-long imaging surveillance after surgery is necessary for these patients. In this pictorial review, multimodal cardiac imaging findings of this rare and potentially fatal coronary artery anomaly are comprehensively discussed, and representative images are provided to facilitate the understanding of this anomaly.
