Vascular injuries of the extremities are associated with a high mortality rate. Conventionally, open surgery is the treatment of choice for peripheral vascular injuries. However, rapid development of devices and techniques in recent years has significantly increased the utilization and clinical application of endovascular treatment. Endovascular options for peripheral vascular injuries include stent-graft placement and embolization. The surgical approach is difficult in cases of axillo-subclavian or iliac artery injuries, and stent-graft placement is a widely accepted alternative to open surgery. Embolization can be considered for arterial injuries associated with active bleeding, pseudoaneurysms, and arteriovenous fistula and in patients in whom embolization can be safely performed without a risk of ischemic complications in the extremities. Endovascular treatment is a minimally invasive procedure and is useful as a simultaneous diagnostic and therapeutic approach, which serve as advantages of this technique that is widely utilized for vascular injuries of the extremities.

Isolated injury to the extrahepatic biliary tract following blunt abdominal trauma is rare, and there is little information especially in children regarding the endoscopic diagnosis and management of occult injury to the biliary tract. We experienced a 5-year-old boy who presented with jaundice 16 days after blunt abdominal trauma and was diagnosed as isolated distal common bile duct stricture by ultrasonography of abdomen. We could get more detailed information about the injury by endoscopic retrograde cholangiopancreatography. We could also manage this isolated common bile duct stricture successfully with endoscopic nasobiliary drainage and plastic stent insertion instead of surgical correction. There appeared to be no recurrence of stricture as evidenced by biochemical test and ultrasonography during 2 years of follow up.

Tracheoinnominate artery fistula is a rare, fatal complication of tracheostomy, and prompt diagnosis and management are imperative. We report the case of tracheoinnominate artery fistula after tracheostomy in a 14-year-old boy with a history of severe periventricular leukomalacia, hydrocephalus, cerebral palsy, and epilepsy. The tracheoinnominate artery fistula was successfully treated with a stent graft insertion via the right common femoral artery. Endovascular repair of the tracheoinnominate artery fistula via stent grafting is a safe, effective, and minimally invasive treatment for patients in poor clinical conditions and is an alternative to traditional open surgical treatment.

We report a case of concurrent saccular aneurysms caused by a penetrating atherosclerotic ulcer of the thoracic and abdominal aorta that were successfully treated by staged endovascular repair. Even though surgical open repair or endovascular repair is the treatment option, use of endovascular repair is now accepted as an alternative treatment to surgery in selected patients. To prevent contrast medium-induced nephropathy and spinal cord ischemia caused by a simultaneous endovascular procedure, a saccular aneurysm of the descending thoracic aorta was excluded by stent graft, followed by the placement of a bifurcated stent graft in the infrarenal abdominal aorta one month later.

A 1-year-old Goffin cockatoo (Cacatua goffini) presented a soft non-painful and balloon-like mass around the cervical area. Subcutaneous emphysema due to cervicocephalic air sac trauma was diagnosed based on history and physical examination, and was confirmed by radiographic examination. Because the cutaneous tab was unsuccessful, a modified syringe stent was carried out. The bird showed no adverse signs for two weeks after implantation. After surgical removal of the stent, the bird did not reveal subcutaneous emphysema.

Common carotid artery (CCA) rupture during parathyroid cancer surgery is extremely rare and is generally life-threatening. We present a case of successful management of a ruptured CCA following the emergency placement of stent-graft in a 59-year-old male diagnosed with recurrent parathyroid cancer. During recurrent parathyroid cancer surgery, his right CCA ruptured unexpectedly, and his vital signs deteriorated rapidly despite surgical management. After stent replacement, his unstable vital signs improved and, thereafter, he was discharged without any complications.

The development of cone beam computerized tomography (CBCT) allows three-dimensional analysis of the patient's anatomy. The surgical guide is a combination of CBCT, computer-aided design/computer-aided manufacturing (CAD/CAM) and implant diagnostics software, which allows well planned prostheses design and ideal implant placement. Guided surgery minimizes possible anatomical damage and allows for more reproducible treatment planning. In this case, the operation time was shortened by using a surgical guide for multiple implants placement in a fully edentulous patient. Immediate loading were performed more easily using preliminary preparation of provisional prosthesis. The patient was satisfied with improved esthetics and chewing function.

Purpose: The appropriate management of traumatic truncal arterial injury is often difficult to determine, particularly if the injury is associated with severe additional truncal lesions. The timing of repair is controversial when patients arrive alive at the hospital. Also, there is an argument about surgery versus stent-graft repair. This study's objective was to evaluate the appropriate method and the timing for treatment in cases of truncal abdominal injury associated with other abdominal lesions. Methods: The medical records at Ajou University Medical Center were reviewed for an 8-year period from January 1, 2001, to December 31, 2008. Twelve consecutive patients, who were diagnosed as having had a traumatic truncal arterial injury, were enrolled in our study. Patients who were dead before arriving at the hospital or were not associated with abdominal organ injury, were excluded. All patients involved were managed by using the ATLS (Advanced Trauma Life Support) guideline. Data on injury site, the timing and treatment method of repair, the overall complications, and the survival rate were collected and analyzed. Results: Every case showed a severe injury of more than 15 point on the ISS (injury severity score) scale. The male-to-female ratio was 9:3, and patients were 41 years old on the average. Sites of associated organ injury were the lung, spleen, bowel, liver, pelvic bone, kidney, heart, vertebra, pancreas, and diaphragm ordered from high frequency to lower frequency. There were 11 cases of surgery, and one case of conservative treatment. Two of the patients died after surgery for truncal organ injury: one from excessive bleeding after surgery and the other from multiple organ failure. Arterial injuries were diagnosed by using computed tomography in every case and 9 patients were treated by using an angiographic stent-graft repair. There were 3 patients whose vessels were normal on admission. Several weeks later, they were diagnosed as having a truncal arterial injury. Conclusion: In stable rupture of the truncal artery, initial conservative management is safe and allows management of the major associated lesions. Stent grafting of the truncal artery is a valuable therapeutic alternative to surgical repair, especially in patients considered to be a high risk for a conventional thoracotomy.

Objective : Surgical experiences of pseudoaneurysms such as traumatic, mycotic and ill-defined unknown causes of aneurysms are rare. The authors have studied the results of surgical management from such cases in our series. Patients and Method : In the last 17 years, 1320 patients with cerebrovascular aneurysms were managed surgically. Among these, 16 patients showed the pseudoaneurysms. The authors analyzed retrospectively the clinical characteristics, treatment methods, management outcomes and problems in the managements. Results : There were 6 patients with traumatic aneurysm, 4 mycotic aneurysms and 6 ill-defined unknown causes of aneurysm. The sites of traumatic aneurysms were cavernous portion of the internal carotid artery(n=3), distal portion of the anterior cerebral artery (n=2) and vertebral artery(VA : n=1). Good outcomes in 5 cases could be obtained by extracranial - intracranial bypass followed by parent vessel occlusion or resection of aneurysm followed by re-anastomosis of parent vessel. The sites of mycotic aneurysm were peripheral portions of middle cerebral artery(MCA : n=3) and posterior cerebral artery(PCA : n=1). The outcomes of the patients with a mycotic aneurysm were relatively poor. It was partially due to the development of new aneurysm after treatment in one. The sites of ill-defined unknown causes of aneurysm were extracranial carotid artery(n=3), V2 portion of the VA(n=1), peripheral portion of the PCA (n=1) and MCA(n=1). Good outcome in all cases could be obtained by resection of aneurysm with or without saphenous vein graft. Conclusion : For the treatments of cerebrovascular pseudoaneurysm, combinations of aggressive medical, endovascular and surgical managements seem mandatory. Insertion of stent for a extracranial carotid artery aneurysm and coiling for a peripheral mycotic aneurysm can be option in future.

The use of IVUS provides information about the lumen and arterial wall, the location and extent of atherosclerotic plaque and the state of the arterial wall after PCi. The use of IVUS after insertion of an intracoronary stent has currently increased, while conflicting evidence exists concerning the long-term benefits of IVUS. We report here on a case of surgical removal of an entrapped and fractured IVUS catheter during insertion of intracoronary stents, and we include a review of the relevant literature.
