Purpose To analyze the success and complication rates and factors associated with technical failure of the ultrasound (US)-guided percutaneous thrombin injection of femoral artery pseudoaneurysms caused by vascular access. Materials and Methods Records of 30 patients with post-catheterization femoral artery pseudoaneurysms who had been treated with US-guided percutaneous thrombin injections in the department of radiology between March 2009 and June 2019 were retrospectively analyzed. The lesion was diagnosed based on US or contrast-enhanced CT. The characteristics of the patients and their lesions were analyzed. Results The mean patient age was 67.8 years. The mean diameter of the pseudoaneurysmal sac was 20.88 mm (5-40 mm). Twenty patients (66.6%) obtained complete thrombosis after the primary injection, while 10 patients (33.3%) obtained partial thrombosis. The number of patients with a low platelet count (< 130 k/µL) was significantly higher in the partial thrombosis group than in the complete thrombosis group (p = 0.02). No substantial procedure-related complications were found in any patient. Conclusion The US-guided percutaneous thrombin injection is considered an initial treatment option for pseudoaneurysms caused by vascular access because of its safety and efficacy.

This patient was an 53-year-old man who had undergone Sengstaken-Blackmore tube insertion for esophageal varix bleeding. Two days after Sengstaken-Blackmore tube insertion, he developed severe left hemothorax and was transferred to our hospital. The esophagoscopic findings revealed a large perforation lengthening 8-cm in the intrathoracic esophagus. A left thoracotomy was performed 33 days after the injury due to repeated varix bleedings and poor conditions. An 8-cm longitudinal perforation of the intrathoracic esophagus with gross suppurative empyema was found. Primary repair and esophageal exclusion was performed 2cm proximal and distal to the perforation, using rows of nonabsorbable staplers(TA stapler 60 $\times$ 4.8) and large bore thoracostomy tubes were placed for local drainage. Six days after intrathoracic esophageal exclusion, an esophagogram revealed a leakage at just above the proximal stapling site. A cervical esophageal exclusion was performed using the same method. One hundred thirty seven days after exclusion operation for the intra-thoracic esophageal perforation, the patient was able to eat per orally without any secondary esophageal reconstructive surgery.

The perforation of the intrathoracic internal jugular vein during the placement of an implantable central venous chemoport is a rare complication that is manifested by hemothorax or hemorrhagic shock. Furthermore, inappropriate instillation of a chemotherapeutic agent in the chemoport can cause chemical pleuritis, and the diagnosis of these complications prior to the instillation of chemotherapeutic agents and open thoracic surgery is mandatory. We report a patient with chemical pleuritis and hemothorax following an inappropriate instillation of a chemotherapeutic agent, through the perforated right internal jugular vein after placement of an implantable central venous chemoport. Treatment by embolization using coils and N-butyl cyanoacrylate, after percutaneous drainage, was successful.

Esophageal perforation is uncommon, however, due to the lack of serosa layer inflammation spread is rapid and common to neighboring structures, leading to significant mortality and morbidity. With an advancement of endoscopic diagnosis there is an increase of esophageal injury and perforation due to esophageal endoscopic procedure. The authors have recently experienced three cases of iatrogenic esophageal perforation following diagnostic endoscopic procedure of the esophagus. We summarize the pervention, diagnostic and therapeutic strategies for iatrogenic perforation.

Foreign bodies in the paranasal sinuses are not commonly observed. Recently, we have observed an interesting case of metalic foreign body (a fragment of bullet) which remained in the posterior part of the left ethmoid sinus for about 30 years, and report here now with a review of literature.

The role of angioembolization has increased because of increases in nonoperative treatment for traumatic splenic injury. We report here a case of successful treatment of iatrogenic pseudoaneurysm of the femoral artery by thrombin injection with coil embolization. A 55-year-old female was admitted to our hospital because of blunt trauma. Computed tomography (CT) revealed a grade V splenic injury with contrast extravasation; therefore, angioembolization was performed. Three days after admission, follow-up CT scan revealed rebleeding from the spleen, and repeat angioembolization was performed. Seven days after admission, an approximately $7.0cm{\times}4.0cm-sized$ pseudoaneurysm was found on follow-up CT scan and there was no bleeding from the spleen. Although thrombin was injected into the aneurysmal sac, there was still inflow of blood, as observed on color-doppler ultrasound. Therefore, coil embolization to the neck of the aneurysm was performed. On angiography, there was no contrast filling into the sac. The size of the pseudoaneurysmal sac had decreased on follow-up CT scan, and the patient was discharged to home without complications. We successfully treated a giant pseudoaneurysm of the femoral artery using thrombin and coil embolization.

Coccidioidomycosis is caused by a dimorphous fungus, Coccidioides, which consists of two species, C. immitis and C. posadasii. Although these organisms are genetically distinct and do not exchange DNA, they appear identical phenotypically and the disease or immune response to the organisms is also identical. Coccidioides grows as a mycelium in the soil and is mainly found in Southwestern United States, northwestern Mexico, and Argentina. An infection usually results from inhaling the spores of the fungus in an endemic area. Patients with a localized infection and no risk factors for complications often require only a periodic reassessment to demonstrate the resolution of the self-limited process. However, patients with extensive spread of infection or high risk of complications as a result of immunosuppression or other preexisting factors require a variety of treatment strategies such as antifungal therapy, surgical debridement, or both. Korea is not endemic area of a coccidioidomycosis. We report a case of disseminated coccidioidomycosis involving the lung and skin, which was detected incidentally after sunburn in a 69 year-old Korean male with diabetes mellitus and iatrogenic Cushings syndrome, with a review of the relevant literature.

A spayed female, 1-year-old, Himalayan, weighing 1.89 kg, was referred. The clinical signs included anorexia, depression, vomiting, urinary incontinence and vaginal discharge for 7 days after elective ovariohysterectomy. In laboratory examination, there was moderate azotemia. Abdominal radiographic findings included heterogeneous serosal detail loss and right renomegaly. Abdominal ultrasonography showed hyperechoic ascites, bilateral polycystic kidneys, right hydronephrosis, and right hydroureter. Excretory urography demonstrated an ureterovaginal fistula. Exploratory laparotomy confirmed this diagnosis and explained that the right ureter had been included in a ligature around the cranial vagina.

Between 1994 to 1998, 7 patients had taken emergency operations by iatrogenic esophageal perforation. To evaluate patterns of injury, clinical presentation, and treatment options for patients, we reviewed all the 7 patients who had gotten transmural injury to the esophagus during dilatations or stenting procedures at our hospital. The primary diagnosis of the patients were as followings , two were achalagia and remaining five were corrosive esophageal strictures. Chest pain, fever, tachycardia were the early signs after esophageal perforation. The sites of perforation were thoracic esophagus in all cases and all of them underwent operation within 8 hours of initial injury. There were no postoperative mortality. Complications were developed three cases： stricture of anastomotic site, mediastinitis due to graft failure of colon and pleural empyema.
