The determination of the normal position of angiographic sylvian triangle was carried out in the 100 Korean subjects over the age of 12 in accordance with Vlahovitch's method for the clinical purpose of evaluating distorsion and displacement of the sylvian triangle in the pathological condition. And each measurement of the anterior and posterior extremities and inferior point of sylvian triangle was compared with the determination by Vlahovitch. The following results were obtained: 1. The anterior extremity of sylvian triangle was close to or on the line MM in the great majority, showing the mean location at 0.89+/-2.69 mm in front of the line. The posterior extremity of sylvian triangle revealed more variable position, at 9.60+/-7.94 mm posterior to the line AA The inferior point of sylvian triangle lies at the junction of one-fourth of AA and one-third of AO with variation of 2.21+/-2.43 mm above the line of one-fourth of AA and 2.28+/-2.04 mm posterior to the line of one-third of AO. 2. Angles of sylvian triangle: Anterosuperior angle:76.28((P-95(12.77(). Posterior angle:27.91((P-95(6.81(). Inferior angle:73.73((P-95(12.49(). 3. Height of sylvian triangle: One-fourth the hemispheric height. 4. Length of superior insular line: One-third the hemispheric height. 5. Distance of superior insular line from external meatus along the hemispheric height: One-half the hemispheric height.

A seven years retrospective study was performed in 45 consecutive vascular injuries in the extremities to investigate the pattern of injuries, managements and outcomes. Motor-vehicle accidents were the leading cause of injuries (80%), followed by industrial injuries (11.1%) and iatrogenic injuries (4.4%). Popliteal and brachial artery injuries were commonly involved (20%). Fifteen (33.3%) patients had fractures, dislocation or fracture dislocation around the knee joint and 6 (13.3%) patients had soft tissue injuries without fracture. Traumatic arterial transection accounted for 34 (75.6%) cases, followed by laceration in 7 (15.6%) and 9 (6.7%) contusions. Associated nerve injuries were seen in 8 (17.8 %) patients using intra-operative findings as the gold standard, both conventional angiogram (CA) and computerized tomography angiogram (CTA) had 100% specificity and 100% sensitivity in determining the site of arterial injuries. The mean ischemic time was 25.31 hours (4 - 278 hours). Thirty-three (73.3 %) patients were treated more than 6 hours after injury and 6 patients underwent revascularization after 24 hours; all had good collateral circulation without distal pulses or evidence of ischemic neurological deficit. The mean ischemic time in 39 patients who underwent revascularization within 24 hours was 13.2 hours. Delayed amputation was performed in 5 patients (11.1%). Of the 6 patients who underwent delayed revascularization, one patient had early amputation, one -had delayed amputation following infection and multiple flap procedures while the rest of the patients’ limbs survived. Joint stiffness was noted in 10 patients (22.2%) involving the knee joint, elbow and shoulder in two patients each. Infection was also noted in 5 patients (11.1%) with two of them were due to infected implants. Other complications encountered included nonunion (2 patients, 4.4%), delayed union (1 patient, 2.2%),limb length discrepancy (1 patient, 2.2%), hematoma (1 patient, 2.2%) and leaking anastomosis in one patient (2.2%). Volkmann’s ischemic contracture occurred in 3 (6.7%) patients. There was no complication noted in 8 (17.8%) patients Three patients (6.7%) died of whom two were not due to vascular causes. We conclude that early detection and revascularization of traumatic vascular injuries is important but delayed revascularization also produced acceptable results
