Injury to the subclavian and axillary arteries is uncommon. Standard surgical techniques require wide exposure and dissection in traumatised areas which is often challenging and associated with significant morbidity, and mortality ranges from 5 to 30%. We report our experience with the endovascular treatment of these injuries. ⋯ Endovascular stent-grafts offer an effective, less invasive alternative to standard techniques in treating traumatic arterial lesions, resulting in shorter procedure time and less blood loss than previously reported.

Incidence, case-fatality rate and clinical pattern of firearm injuries in two cities where arm owning is forbidden.
To review firearm injuries in five hospitals of Douala and Yaounde, both towns of Cameroon, a Sub-Saharan African country where ownership of firearm is forbidden. ⋯ The incidence of firearm injuries in the two largest cities of Cameroon is five to fifty times lower than in many other towns, especially in Western countries. This may be due at least partially, to the current legislation on the ownership of firearm which is very restrictive in this country. Some efforts are however needed to reduce illegal access to weapons and to educate hunters on the safe handling of their gun.

Immediate and early trauma deaths are determined by primary brain injuries, or significant blood loss (haemorrhagic shock), while late mortality is caused by secondary brain injuries and host defence failure. First hits (hypoxia, hypotension, organ and soft tissue injuries, fractures), as well as second hits (e.g. ischaemia/reperfusion injuries, compartment syndromes, operative interventions, infections), induce a host defence response. This is characterized by local and systemic release of pro-inflammatory cytokines, arachidonic acid metabolites, proteins of the contact phase and coagulation systems, complement factors and acute phase proteins, as well as hormonal mediators: it is defined as systemic inflammatory response syndrome (SIRS), according to clinical parameters. ⋯ Endothelial cell damage, accumulation of leukocytes, disseminated intravascular coagulation (DIC) and microcirculatory disturbances lead finally to apoptosis and necrosis of parenchymal cells, with the development of multiple organ dysfunction syndrome (MODS), or multiple organ failure (MOF). Whereas most clinical trials with anti-inflammatory, anti-coagulant, or antioxidant strategies failed, the implementation of pre- and in-hospital trauma protocols and the principle of damage control procedures have reduced post-traumatic complications. However, the development of immunomonitoring will help in the selection of patients at risk of post-traumatic complications and, thereby, the choice of the most appropriate treatment protocols for severely injured patients.

The objective of this study was to assess the utility of emergency ultrasonography in the detection of blunt urological injury. A retrospective review was conducted of all consecutive emergency blunt trauma ultrasonograms (US) obtained at a level I trauma centre from January 1995 to January 2001. Among the 4320 emergency ultrasonograms performed, 596 patients (14%) had intraabdominal injury and, of these, 99 patients (17%) had urological injuries. ⋯ Isolated urological injury was significantly associated with an ultrasonographic pattern of free fluid in the left upper quadrant and the left pericolic gutter (odds ratio=55.1; P<0.001), followed by isolated fluid in the left pericolic gutter (odds ratio=8.6; P=0.04). Although emergency ultrasonography is useful in the triage of patients with blunt urological trauma, it may miss significant urological injury requiring further intervention. As most renal injuries may be managed non-operatively, further studies such as contrast-enhanced CT or angiography should be obtained in the stable patient with suspected blunt urological injury.
