Fifty-four (46.6%) patients had previous ope-ration, with a maximum of 5 surgeries. The average age ofpatients was 35.9 years old,ranging from 6 to 73 years old.Forty-eight (41.4%) Patients had malignant neoplasmas, in-展开更多

The morphology, location, continuity with the parent bone, cartilage cap, perichondrium of tumors, and changes in soft and hard tissues adjacent to the lesions were investigated by two reviewers. Data were analyzed using Mc Nemar test. A P value < 0.05 was considered significant.Results Among the 33 condylar osteochondromas, 11 were of the diffuse type, 10 were of the sessile type, and 12 were of the pedunculated type. Continuity with the cortex and marrow of the host condyle was observed on both CT and MRI. Both modalities had identical detection rates of surface reconstruction of the temporal bone joint, condylar dislocation, and pseudarthrosis formation. However, MRI showed significantly higher detection rates of the cartilage cap and perichondrium than CT(P < 0.05). Furthermore, MRI showed ipsilateral and contralateral temporo-mandibular joint(TMJ) disc displacement in 4 cases and 6 cases, respectively, and ipsilateral and contralateral TMJ effusion in 20 cases and 14 cases, respectively.Conclusion CT can intuitively display the morphology and spatial location of condylar osteochondromas through three-dimensional reconstruction. MRI may be superior to CT in the detection of cartilage cap, perichondrium of the condylar osteochondroma, and changes in the TMJ and adjacent soft tissues.展开更多

Two cases of ruptured aortic aneurysms with severe complication were analyzed. Aorta reconstruction procedures were performed using bifurcated e-PTFE grafts during emergency operation. Diagnosis, preoperadve resuscitation, emergency surgical intervention, and postoperative complications of these patients were summarized and discussed.Results. Rupture of aortic aneurysm in both patients presented as a huge retroperitoneum haematoma by computed tomography scan. They were successfully saved by prompt body fluid compensation, emergency procedure, intraoperative resuscitation, and postoperative intensive care.Conclusions. Correct diagnosis, prompt surgical management, immediate intraoperative proximal aorta clamping during procedure, and effective management of postoperative complications were the key points to successful treatment of ruptured aortic aneurysm.展开更多
