Purpose: Glomus tumors are uncommon benign neoplasms arising from the neuromyoarterial apparatus, usually seen in the nail bed of fingers. Most of this mass presents typical symptoms such as severe pain, point tenderness and hypersensitivity to cold like neuroma, gout or causalgia. Concerning about the origin, there were few written reports about extra-digit glomus tumor, especially that occurred in the skeletal muscule. Methods: A 48-year-old female complained of painful tender mass in her right calf aggravated several months ago. Her MRI and femoral angiogram showed a well defined hypervascular tumor such as hemagioma or hemagioendothelioma in the right calf. Surgical treatment was performed, and it proved glomus tumor in soleus muscle histologically. Results: After the operation, patient didn't complain of her symptoms any more and there was no evidence of recurrence during 1 year follow-up period. Conclusion: Authors have found only eight cases of intramuscular glomus tumor reported in the literature and present here the ninth case of an intramuscular glomus tumor and first case of soleus muscle.

Preoperative angiography is frequently used in the planning of microsurgical reconstruction for identification of vascular abnormality that influence the planning of operation. But, recently 3D CT angiography is considered as new technique that can provide detailed information about vascular anatomy as well as soft and bony tissue without the risks of invasive angiography. 3D CT angiograms were performed in 19 patients before microsurgical reconstruction for the lower extremity and hand between May of 2003 and Oct of 2004. Sixteen of the studies were of the donor site and all of 19 studies were of the recipient site. No complications were found from the 3D CT angiograms. In one case of the bone exposed open wound, the injury of anterior tibial artery was identified and the zone of injury was adequately demonstrated. With the improvement in quality of CT imaging, 3D CT angiograms may provide a favorable alternative to invasive angiography. It is capable of providing high-resolution, three dimensional vascular imaging without the need for arterial puncture and prolonged post-procedure observation. The relation among blood vessels, bones, and soft tissue is well demonstrated in 3D CT angiogram. Also The acquisition time and examination cost were considerably lower in comparison with invasive angiography. In conclusion, this study demonstrates that 3D CT angiography may provide accurate, safe, and cost-effective preoperative imaging. The 3D CT angiography with relatively low morbidity, low cost, ease of image acquisition can have an broader role in microsurgical reconstructive surgery.

Background: We analyzed the long-term results of ascending aortic replacement and arch aortic replacement in acute DeBakey type I aortic dissections to measure the differences in the distal aortic changes with extension of the aortic replacement. Methods: We reviewed 142 cases of acute DeBakey type I aortic dissections (1996-2015). Seventy percent of the cases were ascending aortic replacements, and 3 0% of the cases underwent total arch aortic replacement, which includes the aorta from the root to the beginning of the descending aorta with the 3 arch branches. Fourteen percent (20 cases) resulted in surgical mortality and 86% of cases that survived had a mean follow-up period of $6.6{\pm}4.6years$. Among these cases, 64% of the patients were followed up with computed tomography (CT) angiograms with the duration of the final CT check period of $4.9{\pm}2.9years$. Results: There were 15 cases of reoperation in 13 patients. Of these 15 cases, 13 cases were in the ascending aortic replacement group and 2 cases were in the total arch aortic replacement group. Late mortality occurred in 13 cases; 10 cases were in the ascending aortic replacement group and 3 cases were in the total arch aortic replacement group. Eight patients died of a distal aortic problem in the ascending aortic replacement group, and 1 patient died of distal aortic rupture in the total arch aortic replacement group. The follow-up CT angiogram showed that 69.8% of the ascending aortic replacement group and 35.7% of the total arch aortic replacement group developed distal aortic dilatation (p=0.0022). Conclusion: The total arch aortic replacement procedure developed fewer distal remnant aortic problems from dilatation than the ascending aortic replacement procedure in acute type I aortic dissections.

Congenital abnormalities of the coronary arteries are found in 0.6% to 1.3% of patients in coronary angiography. Dual left anterior descending coronary artery (LAD) is a rare coronary anomaly and is incidentally detected during coronary angiography. We report a case of a 65-year-old female with a rare coronary anomaly who was diagnosed with dual LAD via coronary computed tomography and coronary angiography. The imaging studies revealed dual LAD originating from the left main stem and right coronary sinus. These angiographic findings were considered to be consistent with the type IV variety of dual LAD by Spindola-Franco classification. Recognition of dual LAD is important to prevent errors of interpretation of the coronary angiogram and for optimal surgery.

Blau syndrome (BS) is a rare autosomal dominant, inflammatory syndrome that is characterized by the clinical triad of granulomatous dermatitis, symmetric arthritis, and recurrent uveitis. Mutations in the nucleotide oligomerization domain 2 (NOD2 ) gene are responsible for causing BS. To date, up to 30 Blau-associated genetic mutations have been identified within this gene. We report a novel NOD2 genetic mutation that causes BS. A girl, aged 8 years, and her brother, aged 10 years, developed erythematous skin rashes and uveitis. The computed tomography angiogram of the younger sister showed features of midaortic dysplastic syndrome. The brother had more prominent joint involvement than the sister. Their father (38 years) was also affected by uveitis; however, only minimal skin involvement was observed in his case. The paternal aunt (39 years) and her daughter (13 years) were previously diagnosed with sarcoidosis. Mutational analysis revealed a novel c.1439 A>G mutation in the NOD2 gene in both siblings. The novel c.1439 A>G mutation in the NOD2 gene was found in a familial case of BS. Although BS is rare, it should always be considered in patients presenting with sarcoidosis-like features at a young age. Early diagnosis of BS and prompt multisystem workup including the eyes and joints can improve the patient's outcome.

Objective : We reviewed the feasibility, safety and efficacy as well as the clinical outcome and long-term angiographic results of endovascular treatment (EVT) of the anterior communicating artery (ACoA) aneurysms. Methods : A total of 429 ACoA aneurysms in 426 patients were treated using coil embolization between March 1996 and October 2010 in a single institution. Pretreatment aneurysmal features were checked using angiogram. We had usually used tailored steam shaped microcatheter according to individual angiographic architectures. Immediate postembolization outcomes were evaluated using an angiographic outcome scale and clinical evaluation was performed using the Glasgow Outcome Scale (GOS). Results : Postembolization angiograms demonstrated total occlusion of aneurysm in 290 of 429 (67.6%) aneurysms, neck remnant in 80 (18.6%) and body filling in 59 (13.8%). Dome direction and aneurysm angle was not associated with initial angiographic outcomes. The procedure-related morbidity rate was 0.9% (4 of 429). Clinical and imaging follow-up more than 6 months were available in 382 (89.0%) patients with a mean of 26.2 months. Overall rate of major recanalization was 7.9% (30 of 382) and all of them were retreated without complications. At the last follow-up, 233 (99.2%) of 235 patients had GOS of 5 in unruptured group, and 152 (79.5%) of 191 patients showed good clinical outcomes (GOS of 4 or 5) in ruptured group. Conclusion : Tailored steam shaping of the microcatheter is vital to achieve good angiographic outcomes regardless of aneurysmal direction. EVT is feasible and safe for most ACoA aneurysms with acceptable immediate and long-term outcomes.

The vascular surgery is the field that has developed in early 20 century and is progressing nowadays. Recent advance in surgical technique accompanying with excellent medical diagnosis and treatment, prompt angiographic usage, development of variable prosthetic material, and concomitant use of anti-coagulant have made remarkable results of vascular surgery. 83 cases of vascular surgery have been performed at Thoracic and Cardiovascular Surgery Department of Pusan National Unversity Hosaital since 1971 till 1990, for 20 years and their results are followed. Patient ductus arteriosus and Buerger`s disease were omited in this study. 1. The age distribution shows that the fifth and sixth decades are most frequently affected and mean age was 56.1 years old. Male to female ratio is 1: 2.32. 2. Among the 83 cases of all, number of occlusive vascular disease is 46 and that of aneurysmal disease is 33. 3. In clinical manifestation, most common symptom of occlusive disease is pulselessness and pain was next. Mass sensation is most commonly complained by patients of aneurysmal disease. 4. CT scan was more important in diagnosis of aneurysmal diseases and angiogram was more commonly used in occlusive diseases. 5. The common site of arterial occlusion was common iliac artery, femoral artery, aortic bifurcation, and external iliac artery, as its frequency rate. The most commonly affecting portion of aortic aneurysm was abdminal aorta, and descending thoracic aorta and femoral artery were next 6. Preoperative associated diseases were atherosclerosis[41 cases], hypertension[21 cases], valvular heart disease[11 cases], and diabetes mellitus[9 cases], etc, 7. Operative methods in ocllusive diseases were thrombectomy[36.9%], endarterectomy [10.9%], and bypass graft insertion[52.7%]. Among the bypass graft, Y-graft was used in 7 case, straight graft was used in 17 cases, and saphenous venous graft was used in 2 cases. 8. Postoperative complications were developed in 17 cases, and morbidity rate was 36. 9. Eleven patient were died within 1 month after operation, so operative mortality rate was 13.3%. 10. Duration of patency was beteween 7 and 58 months[average 27.5 months] in occlusive diseases and their 5-year patency rate was 56.3%. Duration of patency of aneurysmal disease was 20 months in aveage and their 5-year patency rate was 51.3%. 11. Patients of eleven cases of occlusive disease and two cases of aneurysmal disease required reoperation for variable reason. 12. 35 cases of patient have used anticoagulants: coumadin, ticlid, and persanthin-ASA combination.

Background: Coronary artery bypases grafting in the old aged is associated with high mortality and morbidity, and it is difficult to perform if the coronary artery is diffusely disease. Recently it has been known that platelet derived growth factor(PDGF), especially PDGF-BB, stimulates angiogenesis. Material and Method: New Zealand white rabbit were used. In an attempt to achieve effevtive cardiac revasculatrization without vascular anastmosis, we divided into three groups(group I : Left anterior descending artery(LAD) was occluded by ligature, group II : Bilateral internal mammary vascular pedicles were dissected and implanted into myocardium, group III : The vascular pedicles were implanted into myocardium and PDGF-BB was injected into the myocardial tissue). Two weeks after IMA implantation, the proximal region of implanted LAD was ligated. Four days after LAD ligation angiogram, triphenyl tetrazolium chloride(TTD) staining and hematoxylin eosin staining were performed. Result: 1. Survival rate in group II was significantly higher than that in group I (P<0.05), and survival rate in group III was signficantly higher than that in group II(53% vs 93%, P<0.01). 2. There were significant differences in the ratio of area of necrosis to area at risk between group I and group II, and between group II and group III (P<0.01). 3. Microangiogram for angiogenic response revealed wide area of extensive revascularization with patent vessels in group III. 4. Histologic findings of three groups showed that polymorphonuclear leukocyte infiltration was minimal in group II and none in group III. Conclusion: PDGF-BB can establish functinal cardiac revasculatization through systemic vessels implanted directly into the myocardium.
