Surgical Treatment of Primary True Aneurysm on the Dorsalis Pedis Vein: A case report / 대한흉부외과학회지

An aneurysm is a focal, localized dilatation of a blood vessel. This term is most commonly applied to dilatation of arteries. However, dilatation can occur in any part of the vascular system. Primary true aneurysm of the superficial venous system that contains all the vascular layers is known to be very rare. We report here on surgically treating a case of primary true aneurysm on the dorsalis pedis vein and we briefly review the related literature.

Clinical Usefulness of Chest Wall Ultrasonography for Detecting Fractures of Costal Cartilage due to Minor Blunt Chest Trauma / 대한흉부외과학회지

BACKGROUND: Rib fractures are the most common injuries that are caused by blunt chest trauma. However, fractures of the costal cartilage generally go unnoticed on chest X-rays unless they involve a calcified cartilage. For this reason, the sensitivity of conventional radiography for detecting rib fractures is low, and especially those involving the cartilaginous part of the rib. Thus, we have evaluated the usefulness of ultrasonography for detecting fractures of the costal cartilage that were overlooked on the conventional radiographs of patients who suffered minor blunt chest traumas. MATERIAL AND METHOD: A total of 45 patients who suffered minor blunt chest trauma and who had no evidence of rib fractures or other major fractures on conventional radiographs were admitted for ultrasonography between April 2008 and March 2009. There were 24 women and 21 men, and the mean age of the patients was 50.4+/-15.91 years (range: 17~76 years). They were examined for the detection of fractures of the costal cartilage by performing ultrasonography with a 7.5-MHz linear transducer. RESULT: A total of 30 patients (67%) had fractures of the costal cartilage, whereas 15 patients (33%) had no evidence of chondral rib fractures. The mean number of fracture sites of the fractured costal cartilage was 1.6+/-0.81 (range: 1~4 sites) in 30 patients. Periosteal hematoma was the most common finding associated with fractures of the costal cartilage (n=7, 17%), followed by sternum fracture (n=5, 12%). However, periosteal hematoma was noticed in 1 patient (2%) who was without fracture of the costal cartilage, and sternum fracture was noticed in 1 patient (2%) who was without fractures of the costal cartilage. CONCLUSION: The results of this study suggest that ultrasonography may be a useful imaging modality for detecting fractures of the costal cartilage that are overlooked on the conventional radiographs of patients who suffer minor blunt chest trauma.
