We experienced thymolipoma which is a rare benign mediastinal tumor, an admixture of atrophic thymic tissue and matured adipose tissue. The patient was, 13 years old boy, admitted due to anterior mediastinal mass on routine chest X-ray and complained of mild exertional dyspnea. The physical examination revealed percussion dullness, decreased breathing sound at right anterior hemithorax. The chest PA and lateral views showed both paracardiac mass density and obliteration of retrosternal clear space. The chest CT Scan showed tubular structure containing of thymic tissue and enhanced fatty tissue, suggested thymolipoma. Operation was performed under the impression of thymolipoma. Through median sternotomy, the huge mass was resected. Grossly, the mass was yellowish fatty colored, measured 15X12X10cm, weighed 600gm. Light microscopic examination showed that thymic tissue containing of Hassal`s corpuscles were surrounded by matured adipose tissue, as the characteristic finding of thymolipoma. The postoperative course was uneventful.

A 61-year-old woman who presented with claudication and dyspnea on exertion was found to have severe calcified narrowing of the descending aorta and severe insufficiency of the aortic valve. These findings were compatible with Takayasu arteritis. To treat these hemodynamic abnormalities, extra-aortic bypass surgery combined with replacement of the aortic valve and ascending aorta-to-hemiarch replacement was performed through a separated upper hemi-sternotomy and limited median laparotomy. We present our successful surgical experience with this case.

Mediastinal paragangliomas are rare tumors that have only been reported in individual cases or limited case series. Surgical resection of these tumors can be challenging, as they are highly vascular and intimately related to the great vessels. Surgery is usually performed via median sternotomy with or without cardiopulmonary bypass. We present the case of a mediastinal paraganglioma that was resected via a left-sided posterolateral thoracotomy. Histopathology revealed a completely resected 38-mm paraganglioma with a positive station 5 lymph node, indicative of locally aggressive disease. Hereditary paragangliomas are associated with malignant transformation; therefore, genetic testing is important. These tumors do not respond well to chemoradiotherapy, and consequently lifelong surveillance for early detection of recurrence is recommended.

The innominate artery is an uncommon site for an aneurysm, and tracheal compression caused by an innominate artery aneurysm is a very rare occurrence. An innominate artery aneurysm can cause catastrophic complications, such as rupture or thromboembolism. The most common surgical approach for open repair is median sternotomy with cardiopulmonary bypass, but cerebral ischemic injury and thromboembolism can occur during surgery. We present the case of a male patient who had an isolated giant innominate artery aneurysm causing tracheal compression, which was successfully managed by surgical repair.

Torso stab injuries near the cardiac box may present unique challenges due to difficulties in hemorrhage control. For a stab injury to the heart, the repair is straightforwardly performed via median sternotomy. In contrast, injuries to the inferior vena cava are challenging to repair, especially when they are close to the diaphragm, and the bleeding can be torrential. Herein, we describe a case of a self-inflicted stab wound within the "cardiac box." The trajectory of the stab injuries went below the diaphragm and injured the infradiaphragmatic inferior vena cava. Successful emergent repair via the thoraco-laparotomy approach revived the young man. In this report, we revisit and discuss previous large series of patients with this rare vena cava injury.

배경: 개심술에서 신속하고 안전한 접근과 미관상 나은 상처를 얻기 위해, 우전외측개흉으로 성인의 심방중 격결손증과 판막질환의 수술을 시행하였다. 방법: 본원에서는 1989년부터 1998년 6월까지 우전외측 개흉술 을 통하여 44예의 개심술을 시행하였고, 수술시간, 심폐우회시간, 대동맥 차단시간, 술 후 출혈량, 중환자실 재실기간, 술 후 퇴원일 등을 정중흉골절개로 수술한 경우와 비교하였다. 결과: 두 군간의 유의한 차이는 없 었고, 전예에서 사망이나 이 접근법과 관련된 이환의 증감은 찾을 수 없었다. 우전외측 개흉술로 안전하고 만족스러운 미용상의 결과를 얻었다. 결론: 우전외측개흉술은 좋은 수술시야를 제공하고 미용상 우수하고 수술의 위험을 증가시키지 않는 부분적으로 정중흉골절개를 대신할 수 있는 안전한 접근법이다.

Background: Median sternotomy can weaken the upper abdominal wall and result in subxiphoid incisional hernia. We evaluated risk factors associated with the development of subxiphoid incisional hernias after coronary artery bypass grafting (CABG). Materials and Methods: Of 1,656 isolated CABGs performed between January 2001 and July 2010, 1,599 patients who were completely followed up were analyzed. The mean follow-up duration was $49.5{\pm}34.3$ months. Subxiphoid incisional hernia requiring surgical repair developed in 13 patients (0.8%). The hernia was diagnosed $16.3{\pm}10.3$ months postoperatively, and hernia repair was performed $25.0{\pm}26.1$ months after the initial operation. Risk factors associated with the development of subxiphoid incisional hernia were analyzed with the Cox proportional hazard model. Results: Five-year freedom from the hernia was 99.0%. Univariate analysis revealed that female sex (p=0.019), height (p=0.019), body surface area (p=0.046), redo operation (p=0.012), off-pump CABG (p=0.049), a postoperative wound problem (p=0.041), postoperative bleeding (p=0.046), and low cardiac output syndrome (p<0.001) were risk factors for the development of the hernia. Multivariable analysis showed that female sex (p=0.01) and low cardiac output syndrome (p<0.001) were associated with subxiphoid hernia formation. Conclusion: Female sex and postoperative low cardiac output syndrome were risk factors of subxiphoid hernia. Therefore, special attention is needed for patients with high-risk factors.

배경: 최소 침습성 심장수술은 기존의 정중 흉골절개술보다 우수한 미용효과, 흉곽 개폐에 있어서의 용이함, 작은 외상에 따른 통증, 감염, 출혈 등의 감소, 빠른 회복 및 재원일수의 감소 등이 장점으로 제시되면서 점차 널리 시행되고 있다. 대상 및 방법: 저자들은 1997년 3월부터 12월 까지 36명의 환자를 대상으로 우측 방정중 절개법, 흉골횡 절개법, 최소흉골절개법 등의 3가지 접근방법으로 대동맥 판막 및 승모판 판막질환, 선천성 심기형의 환자 등에 대해 최소 침습성 심장수술을 시행하였다. 결과: 사망례는 없었다. 합병증으로는 술후 부정맥 4례, 출혈로 인한 재수술 1례, 창상 지연유합 1례가 있었다. 사용된 창상의 평균 길이는 9.1$\pm$0.9cm이었고 중환자실 체류기간은 평균 48$\pm$29시간, 술후 재원기간은 평균 10$\pm$7일 이었다. 결론: 술중 제세동, 탈기, 심장감압 등의 과정에 있어서 어려운 점이 있고 아직까지는 선별된 예에 한해 시행되고 있으나 경험의 축적에 따라 점차 그 적용례가 늘어날 것이라 전망된다.

Purpose: Thoracic traumas represent 10-15% of all traumas and are responsible for 25% of all trauma mortalities. Traumatic cardiac injury (TCI) is one of the major causes of death in trauma patients, rarely present in living patients who are transferred to the hospital. TCI is a challenge for trauma surgeons as it provides a short therapeutic window and the management is often dictated by the underlying mechanism and hemodynamic status. This study is to describe our experiences about emergency cardiac surgery in TCI. Methods: This is a retrospective clinical analysis of patients who had undergone emergency cardiac surgery in our trauma center from January 2014 to December 2016. Demographics, physiologic data, mechanism of injuries, the timing of surgical interventions, surgical approaches and outcomes were reviewed. Results: The number of trauma patients who arrived at our hospital during the study period was 9,501. Among them, 884 had chest injuries, 434 patients were evaluated to have over 3 abbreviated injury scale (AIS) about the chest. Cardiac surgeries were performed in 18 patients, and 13 (72.2%) of them were male. The median age was 47.0 years (quartiles 35.0, 55.3). Eleven patients (61.1%) had penetrating traumas. Prehospital cardiopulmonary resuscitations (CPR) were performed in 4 patients (22.2%). All of them had undergone emergency department thoracotomy (EDT), and they were transferred to the operating room for definitive repair of the cardiac injury, but all of them expired in the intensive care unit. Most commonly performed surgical incision was median sternotomy (n=13, 72.2%). The majority site of injury was right ventricle (n=11, 61.1%). The mortality rate was 22.2% (n=4). Conclusions: This study suggests that penetrating cardiac injuries are more often than blunt cardiac injury in TCI, and the majority site of injury is right ventricle. Also, it suggests prehospital CPR and EDT are significantly responsible for high mortality in TCI.
