Guide wire fracture during percutaneous coronary intervention (PCI) is rare. It can cause fatal complications such as thrombus formation, embolization, and perforation. Guide wire fracture could occur during intervention for severely calcified stenotic lesions, and rarely from distal small branches of stenotic lesions. There are several methods for its management depending on the material character, position, length of the remnant, and the patient's condition. If percutaneous retrieval was not achieved, the surgical procedure should be considered for prevention of potential risks, although the remnant guide wire does not usually cause complications. We experienced a patient with a guide wire fracture during PCI, and managed to prevent its complications through surgical removal of the remnant wire. We report this case here.

Objective: This article concerns evaluation of the sensitivity, specificity and accuracy of FNAB for pre-surgical diagnosis of benign and malignant lesions of major and minor salivary glands of patients treated in the Department of Head and Neck Surgery of Erasto Gartner Hospital. Methods: This retrospective study analyzed medical records from January 2006 to December 2011 from patients with salivary gland lesions who underwent preoperative FNAB and, after surgical excision of the lesion, histopathological examination. Results: The study had a cohort of 130 cases, but 34 cases (26.2%) were considered unsatisfactory regarding cytology analyses. Based on the data, sensitivity was 66.7% (6/9), specificity was 81.6% (71/87), accuracy was 80.2% (77/96), the positive predictive value was 66,7% (6/9) and the negative predictive value was 81.6% (71/87). Conclusion: Despite the high rate of inadequate samples obtained in the FNAB in this study the technique offers high specificity, accuracy and acceptable sensitivity.

Objective : Surgical obliteration of ruptured aneurysm of the proximal posterior inferior cerebellar artery (PICA) is challenging because of limited surgical accessibility. In recent years, coil embolization is the first-choice treatment for these lesions. However, coil embolization is not always easy in ruptured PICA aneurysm owing to the variable anatomical diversity of its shapes, its relationship to the parent artery, its low incidence, and accordingly, lesser neurointerventionist experience. Methods : The parent artery and microcatheter for easier navigation and the embolization technique for stable coiling were identified. Results : This study aimed to identify the more appropriate approach route, microcatheter, and strategies for an easier and safer, and more durable coil embolization in the treatment of lesions in the proximal PICA. Conclusion : Coil embolization for aneurysmal subarachnoid hemorrhage due to a ruptured proximal PICA remains a challenge, but with the appropriate coiling plan, it can be treated successfully.

From Jan. 1981 to Dec. 1991, we had treated 25 patients with congenital coronary art-eriovenous fistulas [CAVF] in Seoul National University Hospital. A retrospective review was made to delineate the course and the management of CAVF and to clarify the role of surgical treatment. Fifteen patients were male and 10 were female with The mean age of 17.4 years[from 3 months to 58 years]. The most frequent symptom was dyspnea on exertion[56%]. Other symptoms were angina and palpitation. Sixty-eight percent of the patients were symptomatic. Fifty-three percent of patients less than 20 years old were symptomatic and 100% of patients over 20 years old were symptomatic. Three patients had multiple CAVFs. The fistula drained into the right ventricle in 13, pulmonary artery in 9, left ventricle in 4, right atrium in 2, and left atrium in 1. Thirteen patients had other associated cardiac lesions. The mean pulmonary-to-systemic blood flow[Qp /Qs] in the isolate CAVF group was 2.19. All patients were operated on to correct the fistulas and other associated cardiac lesions. All patients were followed from 1 month to 11 years without late death. Postoperative complication rate was 24% -significant arrhythmia [3], recurred CAVF[1], psychosis[1], pneumonia [1]. Symptomatic improvement was evident postoperatively. Below 20 years old, 94% of patients were asymptomatic, but above 20 years old, symptoms persisted in 25%. In summary, early elective repair of CAVF is indicated in all patients because of higher complication rate and frequent persistent symptoms in older patients.

Background: Renal cell carcinoma has shown less response to systemic therapies including chemotherapy, radiation, and immunotherapy than other cancers. Surgery has therefore become an important treatment tool. The protocol for treatment is the same for pulmonary metastasis of renal cell carcinoma. We performed surgery for pulmonary metastatic renal cell carcinomas and analyzed the results. Materials and Methods: We retrospectively analyzed 15 patients who had undergone pulmonary metastasectomy from renal cell carcinoma at our hospital from January 2005 to December 2009. Results: No patients had extrathoracic metastatsis. The mean age was 60.2 years (range 35~73). There were 12 male and 3 female patients. The number of synchronous and metachronous patients were 8 and 7, respectively. The mean survival times of synchronous and metachronous patients were 32.6 and 42.9 months, respectively. 6 patients had single lesions and 9 patients had multiple (more than 3) lesions. The surgical procedures included wedge resection (10), lobectomy (2), wedge resection with segmentectomy (2), and segmentectomy (1). Median observation and survival time were 54.1 and 34.9 months. The 1-year and 3-year survival rates were 80% and 50%, respectively. Conclusion: Pulmonary resection for pulmonary metastatic renal cell carcinoma was found to be a safe and effective treatment modality when complete resection was performed.

Arteriovenous malformations (AVMs) are characterized by the presence of abnormal connections between feeding arteries and draining veins. It is generally assumed that symptomatic lesions can preferably be treated. Due to high arterial blood flow, there is a risk of bleeding with surgical excision alone, which can be massive and life threatening during the operation. According to recent advances in interventional technique, a hybrid approach using embolization of the feeding artery with subsequent immediate excision of the AVM for successful management of vascular lesions could be applied to AVMs. Herein, we describe a case of successful excision of AVM in the left soleus muscle using a hybrid approach.

Shone complex is a rare congenital disorder that involves 4 obstructive lesions of the left heart, as follows: parachute mitral valve, supravalvular mitral ring, subaortic stenosis, and coarctation of the aorta. Incomplete forms with 2 or 3 of these lesions in adult patients have been rarely reported in the literature, meaning that insufficient general data exist concerning the surgical strategy and clinical follow-up. Herein, we report the case of a 31-year-old woman with a diagnosis of incomplete form of Shone complex with parachute mitral valve and coarctation of the aorta who underwent successful single-stage surgical repair.

This study aimed to analyse the initial results of five patients with symptomatic osteochondral lesions (OCL) and femoroacetabular impingement (FAI) who were treated successfully with osteochondral autologous transfer (OAT) and femoral neck osteochondroplasty (OCP) through surgical dislocation of the hip. Five patients with FAI and OCL of the femoral head who underwent surgery between 2015-2018 were studied retrospectively. All patients had a grade IV OCL, and the median defect size was 2 cm2 (interquartile range [IQR], 2-2). At the final follow-up, the modified Harris hip score showed a median value of 94 (IQR, 91-95) (P=0.04). Pain evaluation using the visual analogue scale showed a median value of 1 (IQR, 1-2) (P=0.04). Adequate graft union and healthy formation of the chondral surface were observed by magnetic resonance imaging. Although the procedure is demanding, the combination of OAT and femoral neck OCP appears to be an effective alternative in young patients.
