The etiology of thrombosis is multifactorial and involves the interaction of inherited and acquired risk factors. Many neonatal thromboembolic disorders are iatrogenic and their incidence is likely to increase as advancements are made in neonatal care. Among pediatric populations, neonates have the highest risk for thrombosis secondary to the unique developmental hemostatic system, inherited prothrombotic disorders, and perinatal clinical conditions. Central venous and arterial catheters present the greatest risk for developing thromboembolisms in neonates. Both venous and arterial thromboses have been reported in a variety of anatomic locations. Prompt identification and appropriate management of thromboembolisms is critical for avoiding life-threatening complications. To date, few data are currently available regarding the contribution of inherited and acquired prothrombotic disorders in the pathogenesis of neonatal thromboembolism. In particular, a lack of information about neonatal thromboembolism in Korea has inhibited the development of appropriate guidelines for diagnosing thromboembolisms in neonates. An overview of the current knowledge about the role of inherited and acquired risk factors for neonatal thromboembolism in the West and a detailed description of common neonatal thromboembolic diseases is reviewed.

Intralobar pulmonary sequestration is a rare congenital malformation characterized by a cystic portion of the lung that derives its arterial blood supply through aberrant vessel directly of systemic circulation. Two forms of pulmonary sequestration occur; intralobar sequestration is usually contained within the visceral pleura of a pulmonary lobe and its venous drainage to the pulmonary venous system. We presented on case of intralobar pulmonary sequestration with A-V fistula. The patient was 8 years old male and chief complaints are mild fever and exertional dyspnea. Aortogram revealed an aberrant artery originated from thoracic aorta just above the diaphragm and its vessel directly communicated pulmonary vein in sequestrated segment. At time of operation, sequestrated lobe measuring 6x5x5cm, well demarcated at the lower lobe was noted. Aberrant, measuring 1.0cm in diameter and 1cm in length and directly connected pulmonary vein. After division and ligation of the aberrant artery, only excision of sequestrated lobe was performed and complication is not during postoperative course.

Cor triatriatum is rare congenital heart disease which is another variant of anomalous pulmonary venous return. It has abnormal fibromuscular diaphragm between true left atrium and accessary chamber which has one or more orifice to the left atrium. In classic form, the patient dies within several months after birth due to pulmonary hypertension inevitably, so it is rarely found in adult. With priopertive echocardiogram and cineangiogram we had two impressions, left atrial cystor cortriatriatum. At operative finding, there was no visible combined anomaly except accessary chamber which received all pulmonary venous return that drained into the left atrium through small calcified orifice. The operation was performed by simple resection of the diaphragm under cardiopulmonary bypass. The postope rative course was uneventful.

We experienced a case of 49-year-old male patient with amputated two fingers preserved in Soju (Korean traditional liquor, a kind of alcoholic beverages). The amputation level of the two fingers was at the distal interphalangeal joint. The Soju was not an adequate physiologic solution for preserving the amputated tissues. Even though arterial anastomosis was successful, there was no venous drainage visible in the operative field. On the first day after the initial operation, we succeeded in the anastomosis of one vein in one of the two amputated fingers. This was 12 hours after arterial anastomosis was carried out. But no venous dranage was visible in the other finger. In spite of a salvage procedure sustained with external bleeding for 7 days, this replanted fingertip eventually fell into necrosis.

Pelvic ring and acetabular fractures are major high-energy trauma injuries and are often associated with other injuries or fractures. In particular, a venous thromboembolism is an important common complication in trauma patients with pelvic or acetabular fractures. We report a case of a fatal pulmonary thromboembolism after a pelvic fracture in a 60-year-old female patient.

Total anomalous pulmonary venous connection is relatively rare cyanotic congenital heart diaease, which represents 1-4% of all congenital cardiac defects. Generally in the majority cases, severe heart failure and cyanosis develops in the early infancy. Because of high mortality in the untreated infants and surgical risk, there are still many things to be improved. Two patients with total anomalous pulmonary venous connection are presented, which we recently experienced. The one was 10 year old female with supracardiac type drained through left innominate vein, and survived the operation and continuous to do well for 1 year. The other 5 year old female with mixed type (right pulmonary vein drained via coronary sinus and left pulmonary vein through left innominate vein) was operated successfully under hypothermia and extracorporeal circulation, and followed up for 6 months without problem. It was very rare case in the literature.

Mixed Venous oxygenation saturation[SvO2 is a variable determined in part by the externally controlled factors and in part by the patient during CPB. I monitored the SvO2 and tested it as a parameter for the regulation of pump output and as a criteria for the need of inotropics after CPB. With the help of SvO2, I increased the pump flow especially during rewarming for more optimal oxygenation of cells. After CPB, the calculated cardiac index was used as an indicator for the need of inotropic support with greater accuracy and without any clinical problems. I conclude that the SvO2 is an easily checkable variable and a good indicator for optimal oxygenation at cell level, and can be used as an objective criteria for the need of postoperative inotropic support.

Partial anomalous pulmonary venous connection is frequently found in any ASD(atrial septal defect) patients. These patients are usually symptomatic, therefore, easily diagnosed as just simple ASD. We experienced a case of a 37-year-old female patient with ASD in which the left upper pulmonary vein was connected to SVC by the left inominate vein. The patient was diagnosed as simple ASD previously. During cardiac catheterization, we found a meaningful oxygen saturation step up between the SVC and its upper portion. Angiogram confirmed PAPVC. The surgical correction of anastomosis of PAPVC with left atrial appendage and direct closure of ASD were done. The patient was discharged 15 days later.

Strategic planning is integral to any operation but complexity varies immensely and therefore the effort necessary to create the optimal plan. The previous three reports have discussed individual conduits and herein is an attempt to present approaches to common situations which the author favors. Although much has been learned over 45 years about use and subsequent behavior of venous and arterial grafts we continue to learn and, as a result, evolve new strategies or modify those now popular. Thus the reader must recognize that in spite of trying to be balanced and inclusive all surgeons have personal opinions and also prejudices which influence the approach taken and which may not be the optimal one for others or for the patient.

Despite increased utilization of microvascular anastomotic coupler (MAC) devices, the consequences have yet to be fully explored in terms of vascular regeneration. Removal of an exposed venous coupler is described herein, documenting normal circulatory flow through the remodeled site of application. A 25-year-old man who underwent open reduction and rigid fixation elsewhere for traumatic calcaneal fracture ultimately presented with a necrotic postoperative wound. The debrided defect was treated by free thigh perforator flap, incorporating a MAC device. Three months later, the flap remained viable, but the MAC itself was exposed. Structural integrity of the vessel and blood flow were sustained as the device was carefully removed, confirming true vascular remodeling in this example of MAC usage.
