Scapulothoracic dissociation is a rare injury involving separation of scapula from the thorax along with the upper extremity. Majority of the patients have concomitant neurovascular injury and the prognosis is uniformly poor in such cases. We present a case of scapulothoracic dissociation with comminuted fracture of scapula and acromioclavicular joint disruption without neurovascular deficit. There were associated avulsion fractures of the spinous processes of vertebrae (T3-T5). Such presentation is rare in an already rare scapulothoracic dissociation injury. A discussion regarding the probable mechanism of injury, management and prognosis is presented

Conventional surgery for lower lumbar disc herniation is a common practice and its vascular complications have been reported rarely. If the hypotension is severe or prolonged postoperatively, one should suspect vascular injury and perform urgent laparotomy. We experienced two cases of major vascular injuries following hemi-laminectomy and discectomy.

Tension-free vaginal tape (TVT) has been accepted for a therapeutic modality of stress incontinence and presented as easy, safe, effective, and time-saving procedure with cure rate of more than 86% and another 11% significantly improved with no serious complication. However, there is not always safe without severe complications, because the TVT needle has to pass blindly through the pelvic cavity. Furthermore, it may be very serious once it happened. We, herein, present a case who bled to shock following TVT procedure but was controlled conservatively, and review its complications in the literatures.

Surgical correction of a cervicothoracic deformity is difficult with a potential risk of vascular injury. Comprehensive preoperative vascular evaluation is important for safe and successful surgery. The use of multi-detector computed tomography angiography (MDCTA) allows a combined display of vascular and osseous structures of the musculoskeletal system. However, no clinical reports have described the use of MDCTA for surgical planning of anterior cervicothoracic surgery in patients with vascular malformation. The case of a 7-year-old girl with congenital cervicothoracic kyphoscoliosis who underwent preoperative MDCTA evaluation and successful correction is presented in this report.

PURPOSE: To evaluated the effectiveness of abdominal ultrasonography as the initial diagnostic method in blunt renal trauma. MATERIALS AND METHODS: This study was undertaken to compare computerized tomography with abdominal ultrasonography in radiographic staging of blunt renal trauma(Renal Injury scale grade I-V by Moor) except vascular injury. During 3-years period(May 1994 to March 1997), emergency computerized tomography was performed in 66 patients with blunt renal trauma, simultaneously 34 patients among 66 patient were scanned by abdominal ultrasonography. RESULTS: Gross hematuria were present 48% of renal trauma cases. The degree of hematuria showed not correlation with the severity of renal injury(p-value=0.213, by Chi-square test). In diagnostic agreement of abdominal ultrasonography compared to computerized tomography, the diagnostic agreement of minor renal injury(x=0.544, by k2 statistics) was higher than that of major renal injury(r=0.375, by k2 statistics). The overall diagnostic agreement of abdominal ultrasonography in detecting adjacent organ injury was 0.321 (k value). CONCLUSIONS: In ultrasonography imaging, we concluded that minor blunt rectal trauma is not necessary other radiologic evaluation, but major blunt renal trauma should be evaluated by computerized tomography for proper diagnosis of combined injury and diagnostic staging of renal trauma. Renal trauma associated Intraabdominal injury should undergo with ultrasonography-guided paracentesis. Based under result of our study, we suggest the use of abdominal ultrasonography as the initial diagnostic method in blunt renal trauma compatible for prompt diagnosis and treatment.

A case of traumatic internal carotid artery injury associated with skull base fracture, Le Fort II fracture and mandible fracture after maxillofacial blunt trauma which resulted in delayed blindness is presented. This condition would appear to be a rare consquence of maxillofacial trauma. Internal carotid artery injury including dissection is an important consequence of blunt craniomaxillofacial trauma with potentially devastating consquences. It should be emphasized that skull base fracture involving the course of the internal carotid artery provides an important clue to significant vascular injury and, when present, provides the impetus for vascular imaging study.

Because of extensive vascular injury, reconstruction of ring avulsion injury is classically believed to be challenging for a hand surgeon. We report a case of ring avulsion injury treated by debridement of the damaged artery and interpositioning vessel graft with a healthy proper palmar digital artery, which lead to successful functional recovery.

Platelets play an essential role in hemostasis through aggregation and adhesion to vascular injury sites but their unnecessary activation can often lead to thrombotic diseases. Upon exposure to physical or biochemical stimuli, remarkable platelet shape changes precede aggregation or adhesion. Platelets shape changes facilitate the formation and adhesion of platelet aggregates, but are readily reversible in contrast to the irrevocable characteristics of aggregation and adhesion. In this dynamic phenomenon, complex molecular signaling pathways and a host of diverse cytoskeleton proteins are involved. Platelet shape change is easily primed by diverse pro-thrombotic xenobiotics and stimuli, and its inhibition can modulate thrombosis, which can ultimately contribute to the development or prevention of thrombotic diseases. In this review, we discussed the current knowledge on the mechanisms of platelet shape change and also pathological implications and therapeutic opportunities for regulating the related cytoskeleton dynamics.
