For the purpose of establishing laser welding condition(laser power, welding speed and beam focus) and of evaluating tailor welded blank for three kinds of thin steel sheets of SPCC, SK5M and SUS304 using in the thin plate structure such as automobile, train and so on. Their $CO_2$ laser weldability were primarily tested under various welding condition. SPCC and SUS304 thin sheets showed good weldability under some welding condition. But, high carbon steel sheet SK5M needs heat treatment after welding to obtain higher tensile strength and ductility of the welded joint. And next, laser welding condition. Butt-welded specimens were not nearly broken at weld bead. However, base material were ruptured in the direction of circumference. The forming depths by tailor weld bead. However, base material were ruptured in the direction of circumference. The forming depths by tailor welded blank were SPCC+SPCC=22~25mm, SUS304+SUS304=25~43mm and SK5M+SK5M=13~17mm.

A 12-year-old spayed female Cocker Spaniel was presented with vomiting, diarrhea, depression, and hyporexia of 3-day duration. Microscopic examination of the abdominal fluid from a dog showed basophilic, amorphous to fibrillar materials without bile pigments or crystals. Total bilirubin concentration of the fluid was 19 times higher than the serum bilirubin concentration and exploratory laparotomy revealed a ruptured gallbladder and mucoceles in the abdominal cavity. Rupture of gallbladder mucoceles may cause atypical bile peritonitis in which mucinous material is observed instead of bile pigment.

Isolated iliac artery aneurysm (IAA) is rare, but can be fatal. Emergency surgery is performed in cases of hemorrhagic shock due to a suddenly ruptured IAA, which may have a high mortality rate because of massive non-compressible torso hemorrhage (NCTH). Recently, resuscitative endovascular balloon occlusion of the aorta (REBOA) has been accepted as an alternative to aortic cross-clamping via open thoracotomy to achieve hemostasis in trauma patients with profound shock due to NCTH and is considered an emerging bridging therapy for damage control. However, there is limited information on the use of REBOA in non-trauma patients with shock. Herein, we describe a patient with impending cardiac arrest due to isolated ruptured IAA, in whom perioperative bleeding was successfully controlled by REBOA.

Turner syndrome, also described as 45, X, may present with most serious cardiovascular anomalies including risk of aortic dissection and rupture. In emergency situation, management for aortic dissection with complicated anatomy accompanying vascular anomaly is challenging. Here, we report a rare case of ruptured type B aortic dissection with aberrant subclavian artery and partial anomalous pulmonary venous connection in a Turner syndrome. Through right carotid-subclavian artery bypass and thoracic endovascular aortic repair, successful hybrid endovascular management correlated with a favorable result in this emergency situation.

Spontaneous hemothorax is rare, with limited data available on its etiology and treatment. We report a case of massive spontaneous hemothorax with a ruptured variceal phrenic vein during pregnancy, likely a complication of the Kasai procedure. Despite closed thoracostomy, the patient's symptoms and imaging findings did not improve. Emergent open thoracotomy and bleeding control were performed.

We report a case of ruptured sinus of Valsalva aneurysm in 48-year-old male, presenting the symptom of congestive heart failure. Echocardiography showing a hairpin-like sac ex tended from the left coronary sinus to the left ventricle adjacent to the anterior mitral valve leaflet, suggested ruptured sinus of Valsalva aneurysm or aorto-left ventricular tunnel. Operative findings revealed that left sinus of Valsalva aneurysm had multiple openings faced left ventricle, 7 mm in diameter, 20 mm in length. The proximal opening was closed with bovine pericardium and distal openings were closed with spaghetti pledgeted reinforced sutures. The patient was discharged on the 14th postoperative day, and follow up for 8 months uneventfully. This case was reported for its rarity and to describe the techniques of surgical repair.

Objective : The aim of this study was to determine the role of intra-arterial (IA) nimodipine injections for cerebral vasospasm secondary to ruptured subarachnoid hemorrhage (SAH) and to investigate the factors that influence vasodilation and clinical outcomes. Methods : We enrolled 29 patients who underwent aneurysm clipping for ruptured cerebral aneurysms between 2009 and 2011, and who received IA nimodipine after subsequently presenting with symptomatic vasospasm. The degree of vasodilation shown in angiography was measured, and the correlation between the degree of vasodilation and both the interval from SAH to cerebral vasospasm and the interval from clipping to cerebral vasospasm was determined. The change in blood flow rate after IA injection was assessed by transcranial Doppler ultrasound. Multiple clinical parameters were completed before and after IA nimodipine injection to evaluate any improvements in clinical symptoms. Results : For eight patients, Glasgow Coma Scale (GCS) scores increased by two or more points. The regression analysis demonstrated a positive correlation between the change in GCS scores after IA nimodipine injection and the change in blood vessel diameter (p=0.025). A positive correlation was also observed between the interval from SAH to vasospasm and the change in diameter (p=0.040); and the interval from clipping to vasospasm and the change in diameter (p=0.022). Conclusion : IA nimodipine injection for SAH-induced vasospasm led to significant vasodilation in angiography and improvement in clinical symptoms without significant complications. Our findings suggest that IA nimodipine injection should be utilized when intractable vasospasm develops despite rigorous conservative management.
