| 설명 | 선천심장병중의 하나. 태아가 뱃속에 있을 때는 혈액의 흐름이 출생후의 혈액순환과는 다르다. 태아는 호흡을 할 수 없으므로 산소가 있는 혈액을 단지 산모의 혈액에서만 구할 수 있다. 산모의 자궁동맥을 통해 태아의 배꼽정맥으로 넘어간 산화혈액은 간에서 정맥관(ductus venosus)을 거친뒤 심장에 이르게 된다. 심장에 이르른 혈액은 일부는 오른심방에서 곧바로 왼심방으로 가서 다시 좌심실을 거친뒤 대동맥으로 통하게 되지만, 일부는 우심방에서 우심실, 그리고 우심실에서 폐동맥으로 가는 정상출산아와 비슷한 혈액의 경로를 밟는다. 이때 폐는 자궁내에서는 호흡을 할 수 없으므로 폐의 작용이 없게 되고, 따라서 폐동맥으로 건너간 혈액은 폐를 거치지 않고 동맥관(ductus arteriosus)을 통해 곧바로 동맥에 이른다. 이런 태아의 순환은 출생후 호흡이 시작되면, 정상적인 출생 후의 순환으로 바뀌게 된다. 이 경우 태아순환에서만 존재하는 정맥관과 동맥관은 자연히 막히게 되고, 우심방에서 좌심방으로 흐르던 혈액의 순환은 없어진다. 그러나, 경우에 따라 태아순환에서만 유지되는 동맥관이 막히지 않는 병적인 상태가 발생하는데, 주로 미숙아, 혹은 선천성 바이러스 감염 등이 원인으로 추정된다. 이런 경우를 동맥관개존증이라 부르고, 심장은 불필요한 혈액의 흐름을 부담해야 하므로 일찍 심장기능상실(cardiac failure)에 빠지기 쉽다. 열려있는 동맥관의 크기가 작으면, 증상이 가벼워 늦게 치료해도 되지만, 큰 동맥관개존증은 빠른 수술적 치료를 하여야 한다. 일부에서는 저절로 막히기도 한다. |

| ductus thoracicus dexter | One of the two terminal lymph vessels, a short trunk, about 2 cm in length, formed by the union of the right jugular lymphatic vessel and vessels from the lymph nodes of the right superior limb, thoracic wall, and both lungs; it lies on the right side of the root of the neck and empties into the right brachiocephalic vein. Synonym: ductus lymphaticus dexter, ductus thoracicus dexter. (05 Mar 2000) |

| ductus thoracicus | <anatomy> The major efferent lymph duct into which lymph from most of the peripheral lymph nodes drains. Recirculating lymphocytes that have left the circulation in the lymph node return to the blood through the thoracic duct. (18 Nov 1997) |
|---|---|
| ductus hepaticus dexter | The duct that transmits bile to the common hepatic duct from the right half of the liver and the right part of the caudate lobe. Synonym: ductus hepaticus dexter. (05 Mar 2000) |
| ductus lobi caudati dexter | The bile duct from the right half of the caudate lobe, a tributary to the right hepatic duct. Synonym: ductus lobi caudati dexter. (05 Mar 2000) |
| ductus lymphaticus dexter | One of the two terminal lymph vessels, a short trunk, about 2 cm in length, formed by the union of the right jugular lymphatic vessel and vessels from the lymph nodes of the right superior limb, thoracic wall, and both lungs; it lies on the right side of the root of the neck and empties into the right brachiocephalic vein. Synonym: ductus lymphaticus dexter, ductus thoracicus dexter. (05 Mar 2000) |
| plexus aorticus thoracicus | Areolar venous plexus, a venous plexus in the areola surrounding the nipple, formed by the mammary veins, and sending its blood to the lateral thoracic vein. Synonym: plexus venosus areolaris, circulus venosus halleri, Haller's circle, vascular circle, venous circle of mammary gland, thoracic aortic plexus. (05 Mar 2000) |
| skeleton thoracicus | An alternate term for thoracic cage. (05 Mar 2000) |
| nervus thoracicus longus | <anatomy, nerve> Arises from the fifth, sixth, and seventh cervical nerves (roots of brachial plexus), descends the neck behind the brachial plexus, and is distributed to the serratus anterior muscle; it is somewhat unusual in that it courses on the superficial aspect of the muscle is supplies; its paralysis results in "winged scapula". Synonym: nervus thoracicus longus, Bell's respiratory nerve, external respiratory nerve of Bell, posterior thoracic nerve. (05 Mar 2000) |
| nucleus thoracicus | A column of large neurons located in the base of the posterior gray column of the spinal cord, extending from the first thoracic through the second lumbar segment; it gives rise to the dorsal spinocerebellar tract of the same side. Synonym: nucleus thoracicus, Clarke's column, Clarke's nucleus, dorsal nucleus, nucleus dorsalis, Stilling's column, Stilling's nucleus. (05 Mar 2000) |
| bronchus principalis dexter | It arises at the bifurcation of the trachea and enters the hilum of the right lung, giving off the superior lobe bronchus and continuing downward to give off the middle and inferior lobe bronchi. It is shorter, of greater caliber, and more nearly-vertical than the left main bronchus, thus, aspirated objects more frequently lodge on the right side. Synonym: bronchus principalis dexter. (05 Mar 2000) |
| ramus dexter | Of a pair of branches, the branch passing to the right side of the body, to the right member of a bilateral pair of structures, or to the right portion of an unpaired structure; the other member of the pair being a left branch. Synonym: ramus dexter. (05 Mar 2000) |
| ramus dexter arteriae hepaticae propriae | <anatomy, artery> Right branch of proper hepatic artery; terminal branch of proper hepatic artery supplying right lobe of liver; branch: cystic artery. Synonym: ramus dexter arteriae hepaticae propriae, right branch of proper hepatic artery. (05 Mar 2000) |
| ramus dexter venae portae hepatis | <anatomy, vein> Terminal branch of hepatic portal vein distributed to right lobe of liver tributary: cystic vein. Synonym: ramus dexter venae portae hepatis. (05 Mar 2000) |
| ventriculus dexter | The muscular chamber of the heart which accepts blood from the right atrium and pumps it through the pulmonary artery into the lungs. (27 Sep 1997) |
| margo dexter cordis | The border between the sternocostal and diaphragmatic surfaces of the heart; it is fairly well defined in fixed hearts but is rounded and indefinite in the living heart. Synonym: margo dexter cordis, right margin of heart. (05 Mar 2000) |
| pars lateralis rami lobi medii venae pulmonalis dexter superior | lateral part of middle lobar branch of right superior pulmonary vein |
