We report a case of pseudo-pseudoaneurysm, which is a very rare complication of myocardial infarction. A 69-year-old man was admitted to our clinic with chest tightness and dyspnea. He had undergone aortic valve replacement with a pericardial bioprosthetic valve, ring mitral annuloplasty, and reconstruction of an aortic annular defect due to infective endocarditis with bovine pericardium 4 years prior. Echocardiography and computed tomography showed pericardial effusion and a 16-mm cavity at the anterolateral wall of the left ventricle. Magnetic resonance imaging suggested either pseudo-pseudoaneurysm or myocardial abscess. We successfully repaired the myocardial defect using a patch made from a vascular graft with pledgeted horizontal mattress sutures under cardiopulmonary bypass.

Pulmonary artery aneurysm usually carries an ominous prognosis due to the associated pulmonary hypertension. In July 1981, a patient with a huge aneurysm of main pulmonary artery secondary to pulmonary hypertension and bacterial endocarditis due to a patent ductus arteriosus was treated by resection of the aneurysm and Dacron patch graft replacement and closure of the patent ductus arteriosus. The immediate postoperative result was excellent. We now report the surgical treatment, clinical course, and one and half years follow up of the patient.

좌주관상동맥 협착증은 관상동맥 협착증 환자의 약 7%에서 발생될 정도로 관상동맥 협착증 중에서는 드문 질환이며, 특히 좌주관상동맥 협착증이 독립적으로 나타나는 경우는 1% 미만으로 매우 드물다. 그러나 독립된 좌주관상동맥 협착증이 있는 경우에 보편적인 관상동맥 우회로조성술로는 완전한 재관류를 기대할 수 없다. 따라서 이를 극복하기 위해 좌주관상동맥 혈관성형술이 새로이 시도되고 있다. 연세대학교 심장혈관센터에서는 1994년 5월부터 1996년 2월까지 독립된 좌주관상동맥 협착증을 가진 11명에게 혈관성형술을 시행하여 얻은 결과를 평가하고자 한다. 대상환자의 연령은 34세에서 62세 사이로 평균 44.1 $\pm$ 9.3세였다. 이중 남자가 3명, 여자가 8명 (73%)으로 대부분이 여자였다. 수술전 관상동맥 협착증의 위험요소는 당뇨가 1례, 고혈압이 3례, 흡연이 2례, 과체중이 3례 및 가족력이 1례 있었다. 평균 콜레스테롤 치는 196.5 $\pm$ 33.6 mg/dL였으며, 이중 4례에서 200 mg/dL가 넘었다. 수술전 흉통의 정도는 Class II가 6명, Class III가 5명이었으며, 심전도상에서 T inversion이나, ST elevation이 있으면서 심초음파검사에서 좌심실 운동장애를 보인 예가 4례 있었으나 심근경색증을 보인 예는 없었다. 수술전 좌심실 박출계수는 61.1 $\pm$ 5.9%였다. 수술후 좌심실 박출계수는 65.2 $\pm$ 9.1이었고, 좌심실 운동장애를 보인 예는 없었다. 진단은 좌주관상동맥 입구의 협착증이 8명, 근위부 협착이 3명이었으며, 협착정도는 전례에서 60% 이상이었고 이중 5례는 80% 이상이었다. 수술시 접근방법은 모든 예에서 좌주관상동맥의 전방접근을 시도하였으며, 혈관성형술에 사용한 첨포는 소심낭 (bovine pericardium) 을 사용하였다. 동반수술은 전례에서 좌전하행지에 우회로조성술을 시행하였다 (10례 : 좌내유동맥, 1례 : 대복재정맥). 수술시 측정한 협착부위의 직경은 1례가 1 mm, 나머지 10례는 2 mm였으며, 혈관성형술 후에 측정한 직경은 9례가 4 mm, 2례가 5 mm 였다. 수술후 합병증은 하지의 창상감염이 1례 있었으며, 수술사망은 없었다. 추적조사는 100%가 가능하였으며, 추적조사 기간은 평균 15.5$\pm$5.8 개월이었다. 이 기간 중 흉통이 발생한 예는 없었으며, 심전도상 이상소견을 보인 예도 없었다. 수술후 평균 14.4$\pm$3.3 개월에 관상동맥 조영술을 5례에서 시행하였으며, 5례 모두 좌주관상동맥 혈관성형술 부위는 광범위한 개통이 있었으나, 좌전하행지에 이식한 이식편 중 2례에서 중등도의 협착이 있었으며, 나머지 3례도 혈류량이 상당히 줄어든 소견을 보였다. 이상과 같은 결과로 미루어 독립된 좌주관상동맥 협착증이 있는 경우에 비적응증이 되지 않는다면 혈관성형술이 완전한 재관류를 위하여 이상적인 방법으로 생각되며, 단지 좌전하행지에 시행하는 우회로술은 의미가 없을 것으로 생각된다.

The increasing frequency of post-tracheostomy stenosis parallels the increase in the incidence of tracheostomy. The development of stenosis of trachea following the operation of tracheal tumor or tracheostomy is a very serious complication. The continuing need for an adequate tracheal substitute has not been answered, despite the necessities of excision and reconstruction of the trachea to keep for effective ventilation. Experimental tracheal reconstuction, with a prosthesis of heavy Marlex mesh and pericardium, _ vas performed in twelve dogs. Five to six tracheal ring circumferential defects were created and were bridged with heavy Marlex mesh fashioned into a tube of suitable diameter. Group A: A prepared cylinder of Marlex mesh was anastomosed outside the cut ends of the trachea. Group B: The external surface of the prepared cylinder of Marlex mesh was completely covered with suitably sized patch of pericardium and overlapped all margin of the Marlex mesh by 2 to 3 mm in each direction. Group C: The internal surface of the prepared cylinder of Marlex mesh was covered with suitably sized patch of pericardium and overlapped all margin of the Marlex mesh by 2 to 3 mm in each direction. The results of this exepriment were as follow: 1. In group A and B, the graft was well bridged with new granulation and fibrous tissue, and the lumen of trachea kept good patency for effective ventilation.. The interstices of Marlex became uniformly infiltrated with young well vasculated connective tissue. Epithelization has not yet occurred at 4 weeks in each group, but there were evidences of new growing mucosa at grafted site in 6 weeks. The remainder of the prosthesis was completely covered with glistening epithelium and the underlying fibrous tissue became more matured with little inflammation. These findings were more striking in group B than group A. 2. In group C, the covered pericardium was necrotized with stenosis of the lumen of grafted site due to poor blood supply.

Purpose: Hidroacanthoma simplex (HAS) is a rare benign neoplasm of the skin and known as intraepidermal poroma. Malignant transformation of HAS has been reported in the literature, but it is very rare. We experienced a case of malignant hidroacanthoma simplex (MHA) and performed the surgery of the neoplasm. Methods: A 73-year-old patient visited our department for evaluation and treatment of the skin lesion ($3.2{\times}3.0\;cm^2$) that occurred two years before on the right ankle area. The lesion was characterized by dark-brown, hyperkeratotic and protruding patch. The patient had no symptom, and any palpable lymph node was not found on physical examination. The result of laboratory was also nonspecific. The lesion was excised completely with a resection margin of 5 mm including subcutaneous tissue partially, followed by full-thickness skin graft for reconstruction. Results: The result of biopsy was reported as malignant hidroacanthoma simplex. Histologically, the epidermis showed discrete aggregates of tumor cells which had round, hyperchromatic nuclei and pale or clear abundant cytoplasm. Cystic spaces were found within the tumor and mitosis were seen, frequently. No recurrence was found one month after surgery. Conclusion: The case of malignant hidroacanthoma simplex was treated with full-thickness skin graft following wide excision of the tumor.

This is one case report of surgically treated ventricular septal defect [VSD] with aortic insufficiency [AI] at department of thoracic and cardiovascular surgery, Hanyang university hospital. He had had progressive dyspnea on exertion and palpitation for 3 years prior to admission to our hospital. On examination, the blood pressure was 120/0 mmHg and the pulse rate 88 times/min. Bobbing motion of the head, Water hammer pulse, Corringan`s pulse, Quincke`s pulse and to and fro murmur were present. The heart murmur was consistent with .VSD and AI. Cardiomegaly was seen in chest X-ray. EKG, echocardiogram, aortogram and right heart catheterization was performed. On Sep. 9, 1980, open heart surgery was performed under the impression of VSD with AI. Infracrystal type VSD measuring 2 x 1.5 cm in diameter was closed with Teflon patch graft through the transverse ventriculotomy. AI was due to prolapsed, elongated right coronary and noncoronary cusp, especially noncoronary cusp. The prolapsed, elongated aortic leaflets were plicated by placing three 8-figure sutures between the free edge and the base of the leaflet [Frater`s method] through a transverse aortotomy. Postoperatively, he made an uneventful recovery, his blood pressure was 120/70 mmHg and showed no signs AI or residual shunt at discharge.

Congenital aneurysm of sinus of Valsalva is one of the rare congenital heart disease, which is usually asymptomatic until rupture. The aneurysm usually ruptures into a cardiac chamber and produces an aorto-intracardiac fistula. Ruptured aneurysm is a grave lesion in that it causes heart failure and subsequent death. If, however, it is discovered in its early stages and operated on properly, it can be corrected with considerable success. Form January 1975 through December 1984, 18 consecutive patients with congenital aneurysm of sinus of Valsalva underwent corrective surgery using total cardiopulmonary bypass in our department of Thoracic Surgery. 1. The incidence was about 0.9% of surgical cases of congenital heart disease during that period. 2. 13 were males and 5 females, with ages ranging 12 years to 52 years. 3. Associated anomalies were VSD in 14, infundibular PS in 1, aberrant muscle band in RVOT in 1, and secondary aortic insufficiency in 9. 4. 17 were suggested to arise from right coronary sinus and 1 from noncoronary sinus; Among 17, 12 ruptured into right ventricle, and one from noncoronary sinus into right atrium. 5. Surgical correction was performed by means of direct suture closure with combined pledget or patch graft after aneurysm resection, and associated lesions were also corrected simultaneously. 6. There was only one case of operative mortality, and all the other patients were relatively uneventful in their follow-up studies.

The experience with operative treatment for total correction of Fallot at the department of Thoracic and Cardiovascular Surgery, Keimyung University Dong San Medical Center from July 1980 to July 1984 was reviewed. There were 37 males and 12 females and their ages ranged from 3 years to 30 years, with the average age of 12.2 years. Sixty nine point four percent of patients were younger than 15 years of age. The most frequent type of right ventricular outflow stenosis was the combined type [pulmonary valvular and infundibular stenosis] containing 41 patients [83.7%] and there were 9 deaths in this group. The major associated lesions included Patent foramen ovale in 20 patients [40.8%], Atrial septal defect in 7 patients [14.3%], Left superior vena cava in 4 patients [8.2%], Right sided aortic arch in 2 patients [4.1%] and Patent ductus arteriosus in 11 patient [2.0%]. The pulmonary valvotomy was performed in 41 patients and patch graft reconstruction of the right ventricular outflow tract was performed in 23 patients. In 11 patients the monocusp patches were used. Thirty-five patients [71.4%] had the right bundle branch block postoperatively. There were 11 postoperative deaths with hospital mortality rate of 22.4% and the leading causes of death were low output syndrome, bleeding, and cerebral embolism.
