- Cystic tumors of the pancreas where a pseudocyst has not been able to be excluded has been considered potentially proliferative and pre-malignant or malignant and thus aggressive surgical approach has been advocated. Retroperitoneal cystic tumors are rare and among these bronchogenic cysts are extremely infrequent. The present paper describes a case of bronchogenic cyst in association with the pancreas in which diagnostic work-up was not able to exclude a proliferative pancreatic cystic tumor.

- Background Transarterial particle embolization is a common treatment of uterine fibroids, aiming to obtain ischemia resulting in shrinking of the fibroid with preservation of normal uterine tissue. Embolization with non-degradable microspheres is established, but causes permanent occlusion of the arteries, affecting both the uterus as well as the fibroids. Purpose To evaluate in vivo degradation, local tissue effects, and possible recanalization following intra-arterial deposition of the new, degradable starch microspheres (DSM), in a short-term experimental pilot study. Material and Methods Under general anesthesia, unilateral transarterial embolization of the uterine artery (UA) with DSM 500-700 μm was performed in five female sheep. The animals underwent renewed angiography at different intervals after embolization (19-65 h) and were subsequently sacrificed. Histological examination was performed. Results Embolization with absent flow in the UA could be completed in five of six animals. At final angiographic evaluation, recanalization of the embolized arteries was evident in three sheep. At the gross postmortem examination, edema and discoloration indicating ischemia of the uterus at the embolized side, was observed in all the sheep. At histopathological examination, different stages of DSM degradation in the arterial branches were observed in both endometrium and myometrium. Mild-to-moderate vasculitis and mild-to-extensive ischemic changes were present along with degeneration of the uterine glands. Conclusion This short-term pilot study proved efficacy of embolization with DSM causing ischemic changes in the embolized organ, but also degradation of the DSM with subsequent recanalization of the embolized arteries.

- A 92-year-old man with dysphagia secondary to squamous cell carcinoma of the esophagus was palliated repeatedly with endoscopic laser therapy and insertion of esophageal stents. During the treatment period of 32 months, the patient could be fed perorally while ingrowth of tumor, development of new stenoses at the edges of the stents, and breakage of one stent were encountered. A tracheoesophageal fistula developed at the upper edge of the first stent. The patient died from aspiration pneumonia. At autopsy, no cancer cells were found in the esophagus. Combined endoscopic laser treatment and stent therapy may keep a patient free from dysphagia during a long period of time and also may result in the complete disappearance of tumor growth in the esophagus.

- A 67-year-old woman resented with an acute type A aortic dissection, which was treated surgically with aortic valve replacement as a composite graft with reimplantation of the coronary arteries. At the end of surgery, a left-ventricular venting catheter was placed through the apex and closed with a buffered suture. Consecutive computed tomography (CT) examinations verified a growing apex pseudoaneurysm. Communication between the ventricle and the pseudoaneurysm was successfully closed with an Amplatz septal plug by the transfemoral route. Follow-up CT showed an additional pseudoaneurysm, which also was successfully closed using the same method.

Non-traumatic vascular emergencies: imaging and intervention in acute arterial conditions

- Methods of imaging and intervention in acute non-traumatic vascular arterial conditions has changed substantially during recent years. Computed tomography, MRI angiography and, more recently, intravascular ultrasonography (IVUS) have replaced to a large extent conventional diagnostic angiography. An increasing number of patients are treated by endovascular interventions and numerous new treatment methods have been evaluated. Technical development of new equipment and instruments, increasing skill of interventional radiologists and better understanding of events following interventions improve continuously results of the treatment. Radiologic diagnosis and intervention have important roles in the treatment of acute non-traumatic vascular arterial conditions.
