Functional Intracardiac Paraganglioma
정용우,최재웅,김경환 대한흉부외과학회 2020 Journal of Chest Surgery (J Chest Surg) Vol.53 No.2
A 39-year-old man presented to the department of emergency medicine in Seoul National University Hospital complaining of chest pain, heart palpitation, and headache. Upon arrival, a computed tomography scan showed a 7.0 cm×6.2 cm lesion with the typical features of a paraganglioma. The patient was treated with an alpha-blocker and a beta-blocker prior to surgical intervention. We removed the tumor successfully, and histopathologic findings indicated that the tumor was indeed a paraganglioma. Since intracardiac paraganglioma is a rare disease, we present this case together with a literature review.

Colonic varix, which is a rare cause of lower gastrointestinal bleeding, can be developed by various diseases. Colonic variceal bleeding is more fatal than esophageal variceal bleeding. Klippel-Trenaunay-Weber syndrome is a rare congenital vascular malformation characterized by the clinical triad of bony or soft tissue hypertrophy, hemangioma and varicosities or vascular malformations. We report a 42-year-old female patient with fatal sigmoid variceal bleeding. She had dilated vessels over her body and face, and both superior and inferior vena cava were obstructed. She underwent an emergent operation due to uncontrolled massive bleeding from sigmoid varices. We report a case of Klippel-Trenaunay-Weber syndrome with literature review. (Korean J Gastrointest Endosc 2003;27:21-25) 결장 정맥류는 하부 위장관 출혈을 유발하는 매우 드문 질환으로 다양한 원인에 의해 발생한다. 일단 출혈이 발생하면 식도 정맥류 출혈보다 매우 치명적이다. Klippel-Trenaunay-Weber 증후군은 모세혈관기형, 심부 정맥류, 사지의 기형 등이 특징인 드문 질환이다. 저자는 전신과 안면에 혈관 확장, 대장 내시경검사에서 S자결장 정맥류가 있고, 상대 정맥과 하대 정맥이 동시에 폐쇄되었으며 신체 기형이 있는 Klippel-Trenaunay- Weber 증후군 환자에서 심한 정맥류 출혈로 S자결장 부분절제술을 시행한 예를 경험하였기에 문헌 고찰과 함께 보고한다.

It is important to know the degree of disturbance when evaluating the soil strength parameters from laboratory test. In this study, suction tests and unconfined compression strength tests were carried out to investigate the degree of disturbance of sample with soft marine clay of Kwangyang. Based on the test results, suction test is a good quantitative analysis for the degree of disturbance and shows a similar tendency with the results of unconfined compression strength test.
