In contrast, aggressive operative interventions may decrease the morbidity and mortality in such patients. These operative treatments include craniotomy for evacuation of the hematoma, stereotactic positioning, and neuronavigational-guided hemorrhage puncture and drainage. Here, we report a novel and relatively simple procedure to achieve satisfactory outcomes in a patient with a brainstem pontine hemorrhage.<strong> Case Presentation:</strong> A 53-year-old man who was diagnosed with brainstem pontine hemorrhage. On hospital day 6, he underwent CT-guided, virtual stereotactic puncture and catheter drainage of this brainstem pontine hemorrhage. Medical treatments were continued after this procedure. On postoperative day 16 (hospital day 22), the patient was discharged from the hospital, awake and able to answer questions appropriately. Muscle strengths were grades V and IV for the left and right extremities, respectively. The patient was continued with active rehabilitation and achieved a Barthel index of 85 points at one month after the percutaneous drainage procedure. <strong>Conclusion:</strong> CT-guided, virtual stereotactic percutaneous transcranial puncture and catheter drainage for brainstem pontine hemorrhages has obvious potential advantages and offers a possible alternative to achieve the best outcomes with minimal operative trauma compared to open microcraniotomy.展开更多

Pancreatic TB is more frequently associated with miliary TB or widely disseminated disease. Pancreatic TB may present as cystic or solid pancreatic masses, pancreatic abscess or acute or chronic pancreatitis. Majority of the cases are diagnosed after surgical exploration for presumed pancreatic malignancy and preoperative diagnosis is quite difficult. However, improvement in imaging techniques and the resulting imageguided interventions gradually can obviate the need for more invasive diagnostic surgical procedures and expedite the planning of therapy. Herein, we report a rare case of isolated pancreatic TB which presented with pancreatic mass lesion in an immunocompetent host. Diagnosis was made by contrast enhanced computed tomography and guided fine needle aspiration of the pancreatic mass which revealed acid-fast bacillion Ziehl-Neelsen stain. The case was treated successfully with antituberculous drugs. Pancreatic tuberculosis should be considered in the differential diagnosis of a pancreatic mass when the patient is young, residing in the endemic zone of tuberculosis. Every attempt should be made to diagnose the cases to prevent unnecessary operation.展开更多

However, in some of the metastatic lymph nodes in the middle mediastinum, the percutaneous approach cannot be used safely due to possible damage to surrounding anatomical structures. We established an animal model (group of 12 pigs) to assess the safety and feasibility of computed tomography (CT)-guided vena cava puncture. Methods: Under CT guidance, an 18G needle was used to puncture the anterior wall of the anterior vena cava (AVC) in 12 pigs. The 18G needle was chosen as it is similar in size to the needles employed for clinical application in brachytherapy. The incidence of complications and vital signs was monitored during the procedure. Thoracotomy was performed to remove AVC specimens, which were analyzed for histological evidence of vessel wall damage and repair. Results: Following postoperative enhanced CT, two animals were found to have a small pneumothorax (one being hemopneumothorax). The intraoperative oxygen saturation of both animals was not significantly decreased and was maintained at 93-100%. No animals developed mediastinal hematoma. Preoperative, intraoperative, and postoperative changes in blood pressure, heart rate, hemoglobin, and blood oxygen saturation were not significant. Histological evaluation of AVC specimens showed that by 7 days following the procedure, the endothelial layer was smooth with notable scar repair in the muscularis layer. Conclusions: CT performed after the procedure and histological preparations confirmed the safety of the procedure. This indicates that percutaneous brachytherapy for metastatic middle mediastinal lymph nodes can be carried out via the superior vena cava.展开更多
