Abstract
OBJECTIVE To evaluate the efficacy and safety of evacuation of spontaneous supratentorial hemorrhage with double targets-single channel and multiaxial stereotaxis. METHODS Thirty-four patients with supratentorial intracerebral hemorrhage, who underwent hematoma evacuation with the method of double targets-single channel between January 2014 and November 2014 in the Second Affiliated Hospital, Zhejiang University School of Medicine, were included in the study. We classified the hematoma into four types based on the principle of double targets-single channel calculation method (DTSC). And the appropriate stereotactic surgery path and operation opportunity were designed individually according to the hematoma volume and mass effect. Twenty-seven patients with supratentorial hemorrhage who underwent hematoma evacuation with the method of single targets-single channel between January 2013 and November 2014 were selected as single target group. RESULTS Volumes of initial hematoma in DTSC and single target groups were(38.6 ± 19.2)mL and(40.1 ± 18.1)mL, respectively. Initial Glasgow Coma Scale were 9.6 ± 3.2 (3~15) and 9.1 ± 2.9(3~13) (all P >0.05). Residual volume of hematoma and clearance ratio were (11.1 ± 4.2) mL and(73.1 ± 5.4)% in DTSC group and (18.5 ± 5.3) mL and(55.1 ± 5.1)% in single target group by CT scan 24 h after operation(all P <0.05). There was no significant difference in Glasgow Outcome Scale between two groups in one-month follow-up. Average length of postoperative stay of two groups were(12.6 ± 9.8)d and (14.2 ± 7.1)d, respectively. CONCLUSION Evacuation of spontaneous supratentorial intracerebral hematoma with DTSC and multi-axial stereotaxis can increase clearance ratio remarkably and decrease average length of stay.

Abstract
The progress in noninvasive imaging techniques for aortic pathology, such as computed tomography (CT), magnetic resonance (MRI) and transesophageal echocardiography (TEE) have facilitated the diagnosis and management of patients with aortic intramural hematoma (IMH). Despite incomplete understanding of their natural history, it is known there is no significant difference between the IMH and classic aortic dissection (AD) on the incidence of major complication or death. In this article, we present images of patient with type B aortic hematoma and different outcomes in their natural evolution.

Abstract
BACKGROUND AND PURPOSE In patients with intracerebral haematoma (ICH) secondary to ruptured aneurysm or arteriovenous malformation (AVM), conservative therapy and follow-up without angiographic evaluation is associated with a risk of recurrent bleeding. It is necessary for a clinician to identify a subgroup of patients with spontaneous supratentorial ICH who are likely to harbour high-flow vascular malformations that require specific treatment - neurosurgical or neuroradiological. A new CT-based classification for supratentorial ICH aimed at a close correlation between ICH localization and occurrence of high-flow vascular malformations diagnosed on angiography is presented. MATERIAL AND METHODS According to the proposed classification, supratentorial ICHs are divided into deep and cortico-subcortical. The deep group is further subdivided into striatocapsular, lobar ICH and isolated intraventricular haemorrhage and the cortico-subcortical group into paracisternal and convexity ICH. A new classification was used in a consecutive series of 108 patients with spontaneous supratentorial ICH subjected to angiographic evaluation. RESULTS Deep ICH in non-hypertensive patients was secondary to AVM rupture in 57.1% (8/14). High-flow vascular malformation was a source of bleeding in 93.6% of patients with paracisternal ICH - aneurysm in most cases (41/47). Convexity ICH was found to be AVM-related in 35.7% of patients (5/14). CONCLUSIONS Our clinical experience shows that the proposed classification appears to be closely associated with angiographic findings. Its clinical application with consideration of other factors such as age and arterial hypertension may help clinicians to identify high-risk ICH patients for angiographic evaluation and further specific treatment to prevent rebleeding.

Abstract
BACKGROUND/AIMS Post discharge prescriptions and follow-up protocols after non-operative treatment of blunt liver injuries are still controversial. The aim of this study was to detail the evolution of the hepatic injuries considering their different patterns and severity grades, stated by the Liver Injury Scale. METHODOLOGY Analysis of a database concerning 79 consecutive patients submitted to ultrasound follow-up until complete recovery of liver injury. RESULTS All patients had an uncomplicated course and the liver restoration was demonstrated between 3 and 300 days after the trauma. The median healing time of hematomas increased with the grading (p<0.001): 6 days (IQR=6.75), 45.5 days (IQR=91) and 108 days (IQR=89) for I, II and III grade lesions, respectively. Similarly behaved the lacerations and 29 days (IQR=14.25), 34 days (IQR=43.5) and 77.5 days (IQR=83.5) was the median healing time of II, III and IV grade lesions, statistical significance emerging only comparing II to IV grade lacerations (p<0.035). Considering the different lesion patterns within the same severity grade, the liver restoration was more prompt after lacerations (p<0.001). CONCLUSIONS These data suggest that medical prescriptions and follow-up protocols can be tailored considering the lesion characteristics.

Abstract
While calcified cephalohematoma is eminently correctable, a clear description of indications for surgery and surgical techniques are currently lacking in the literature. In this paper we propose a simple classification and an algorithm for the management of cephalohematomas. Three patients were treated for large calcified parietal cephalohematomas. Craniectomy and cranioplasty were performed with excellent outcome. Cranioplasty was performed with the cap radial craniectomy technique in two patients and the flip-over bull's-eye technique in one patient. The literature was reviewed on this entity and an algorithm based on the timing of presentation, extent of calcification and type of calcified cephalohematoma is proposed. Aspiration and compressive dressings can be used for early, incompletely calcified cephalohematomas. Calcified cephalohematoma causing significant distortion of the calvarium requires surgical correction and is classified as Types 1 or 2 depending on the contour of the inner lamella. Type 1, with a normal contoured inner lamella, can be corrected by ostectomy of the outer lamella. Type 2 calcified cephalohematoma has a depressed inner lamella. Elevation of the inner lamella is necessary and the cap radial craniectomy technique can be used. We describe a novel technique, the flip-over bull's-eye techniques as an alternative technique for Type 2 lesions in selected patients. In conclusion, calcified cephalohematomas can safely be treated surgically with excellent outcome. It is hoped that this algorithm will serve as a useful and logical guide in decision making for the management of this condition.

Abstract
BACKGROUND The purpose of this study was to reevaluate extension of traumatic retroperitoneal hematoma (RH) and related management strategies in light of the new concept of retroperitoneal fascias as interfascial planes communicating with three compartments. METHODS Diagnostic computed tomographic images of 169 patients with traumatic RH treated between 1997 and 2003 were retrospectively reviewed. The extension of RH was measured in relation to 10 components: 3 compartments and 7 parts of the interfascial planes. On the basis of careful horizontal and vertical assessment of computed tomographic images, distribution, extent, and volume in each component of RH were assessed. RESULTS In 88.8% of patients, RH was detected in interfascial planes. Interfascial planes absorbed a large amount of hematoma (mean, 223 +/- 309 mL; range, 0-1,519 mL), whereas the anterior and posterior pararenal spaces absorbed only 5 +/- 16 mL and 21 +/- 30 mL, respectively. The volume of RH in interfascial planes accounted for 78.1% of the total volume. In all cases, RH spread within interfascial planes with regularity: transversely by means of retromesenteric planes and vertically by means of combined interfascial planes. Regular extension patterns allowed RH to be classified by bleeding source. RH originating from retrorenal or combined interfascial plane had a poor prognosis; 51.7% of such patients died as a result of uncontrollable hemorrhage. CONCLUSION RH was based in the interfascial planes, not the three compartments. Our findings that RH extends and is largely confined within interfascial planes, regardless of cause or volume, could be useful in estimating the extent of RH and developing breakthrough strategies for RH.

Abstract
UNLABELLED 99mTc-methoxyisobutylisonitrile (MIBI) SPECT has been reported to be 100% sensitive and specific in the early differential diagnosis between neoplastic and nonneoplastic intraparenchymal cerebral hemorrhage (ICH), because nonneoplastic ICH does not show 99mTc-MIBI accumulation on SPECT examinations performed within 48 h from the onset of clinical symptoms. The aims of this study were to investigate the behavior of nonneoplastic ICH on more delayed 99mTc-MIBI SPECT examinations and to determine how the timing of examination affects the reliability of 99mTc-MIBI SPECT in differentiating neoplastic from nonneoplastic ICH. METHODS We prospectively enrolled 32 patients with acute neurologic deterioration caused by nontraumatic ICH. Patients were randomly allocated to 4 groups of 8 patients each. Patients in the first, second, third, and fourth groups underwent 99mTc-MIBI SPECT 2, 5, 10, and 30 d, respectively, after the onset of clinical deterioration. Furthermore, patients in the first group underwent a second (99m)Tc-MIBI SPECT examination at 30 d. 99mTc-MIBI SPECT studies were visually and semiquantitatively evaluated. Patients were followed up to confirm the nonneoplastic etiology of the ICH. RESULTS Two of the 32 studied patients, 1 in the second and 1 in the fourth group, were excluded because the ICH turned out to be related to a neoplastic lesion. Visual analysis showed no 99mTc-MIBI uptake in any patient studied at 2 d, whereas increased radiotracer uptake was found in 1 (14%) of 7, 5 (62.5%) of 8, and 5 (71%) of 7 patients studied 5, 10, and 30 d, respectively, after clinical deterioration. Moreover, with the semiquantitative analysis, a statistically significant difference was found among 99mTc-MIBI indices in the 4 groups (P = 0.0011). All patients in group 1 showed a significant 99mTc-MIBI accumulation when studied at 30 d. CONCLUSION Nonneoplastic ICH, showing no 99mTc-MIBI uptake within 2 d, can show 99mTc-MIBI accumulation on more delayed imaging. 99mTc-MIBI SPECT can clearly differentiate between neoplastic and nonneoplastic ICH only during the acute phase. Our findings suggest that examination be performed early after the onset of symptoms and certainly within 5 d.

Abstract
OBJECTIVE To evaluate the clinical usefulness of the classification for renal injury, proposed by Japanese Association for the Surgery of Trauma (JAST). METHOD JAST classification for renal injuries consists of categories as: Type I (subcapsular injury); Type II (superficial injury); type III (deep injury); type IV (pedicle injury). Type III injuries are subclassified into: IIIa (deep laceration); IIIb (transection); IIIc (fragmentation). Type IV are subclassified as: IVa (M), IVa (S) (the occlusion of main or segmental renal artery); IVb (renal vessels laceration). Each of the degrees of severity in hemorrhage (H factor) and extravasation of urine (U factor) should be appended as: H0, U0 (not recognized); H1, U1 (remaining within perinephric space); H2, U2 (extending through Gerota's fascia); H3, U3 (extending to contralateral side). We examined the initial management and overall outcome of blunt renal injuries recorded at our institute. All patients were classified according to the JAST criteria. Statistical analyses were applied to find the correlations between type and H factor, and between type and U factor. We also determined which parameter (type, H or U) is the most significant factor responsible for the outcome of treatment in the injured kidney. RESULT One hundred and fifteen consecutive cases of blunt renal injuries from 1982 to 1999 were investigated. Significant correlations were observed between type (I-IIIc) and H factor, and also between type (IIIa-IIIc) and U factor. Twenty-nine patients (25%) underwent immediate surgical exploration; 1 (2%) in type I or II or IVa (S), 5 (18%) in IIIa, 4 (50%) in IIIb, 7 (100%) in IIIc and 12 (100%) in IVa (M) or IVb. Among the 86 conservatively-managed patients, TAE or surgical intervention was required later in six patients. Nineteen (17%) patients were nephrectomized. The renal loss rates were 0% in type I or II or IVa (S), 7% in IIIa, 25% in IIIb, 57% in IIIc and 92% in IVa (M) or IVb, respectively. The differences of severities of the type and the H factor are statistically significant between the groups of injured kidney preserved and lost. Logistic regression analysis suggested that the type was an independent factor predicting outcomes of injured kidneys. CONCLUSION It seemed that the type category is most useful when managing patients with renal injuries and also evaluating outcomes of them.

Abstract
Traumatic retroperitoneal hematoma (RPH) may arise from injury to bony structures, major blood vessels, and intestinal or retroperitoneal viscera. To categorize the management of RPH, the retroperitoneum may be divided into three zones. Zone 1 (central) extends from the esophageal hiatus to the sacral promontory. Zone 2 (lateral) extends from the lateral diaphragm to the iliac crest. Zone 3 (pelvic) is confined to the retroperitoneal space of the pelvic bowl. For the traumatized patient with RPH, laparotomy is mandated by persistent hemodynamic instability despite intensive volume replacement. The judgment of whether and when to explore the retroperitoneal hematoma is guided by the mechanism of injury (blunt or penetrating) and the location of the RPH. RPH localized to the upper central area (Zone 1) after penetrating trauma implies injury to the great vessels and always requires urgent surgical exploration. RPH in other zones should be evaluated by CT and/or angiography; ongoing hemorrhage may respond to therapeutic embolization.

Abstract
UNLABELLED Distinguishing neoplastic from nonneoplastic intracerebral hematoma has great clinical relevance for the appropriate management of patients. Imaging is not always able to clearly identify a tumor-related intraparenchymal cerebral hemorrhage (ICH), especially in the acute phase, the diagnosis being frequently based on evolution patterns. The aim of this study was to test the value of (99m)Tc-methoxyisobutylisonitrile ((99m)Tc-MIBI) SPECT as a noninvasive diagnostic tool in early diagnosis of hemorrhagic brain neoplasm. METHODS We prospectively studied 29 patients harboring a nontraumatic acute onset of clinical deterioration caused by ICH with atypical clinical or neuroradiologic features. All patients underwent (99m)Tc-MIBI SPECT within 48 h from the clinical onset. Early and delayed images were obtained. Both visual and semiquantitative analyses were performed. The (99m)Tc-MIBI index was obtained from both early and delayed images and the retention index was calculated. RESULTS In 19 patients (65.5%), a nonneoplastic hemorrhage (15 vascular degenerative diseases, 2 cavernous angiomas, 1 thrombosed middle cerebral artery giant aneurysm, and 1 sinus rectus thrombosis) was diagnosed by clinical and neuroradiologic follow-up or open surgery. In 10 patients (34.5%), a neoplastic hemorrhage (6 metastases, 2 glioblastomas multiforme, 1 ependymoma, and 1 intracranial angioblastic meningioma) was diagnosed by direct histologic typing (open surgery or stereotactic biopsy). In all neoplasm-related hemorrhages, a focal increased tracer uptake was observed in the area of the lesion, whereas no focal increased tracer uptake was noted in all nonneoplastic hematomas. A wide cutoff in the early ratio between neoplastic and nonneoplastic hemorrhages was found. Moreover, a statistically significant difference was found in the delayed ratio (P < 0.01) and the retention index (P < 0.05) between the 2 groups. CONCLUSION Our data suggest that (99m)Tc-MIBI SPECT could play a role in the early noninvasive diagnostic work-up of hemorrhagic brain lesions, allowing a clear differentiation between neoplastic and nonneoplastic ICHs. The high availability and low cost of this nuclear medicine technique can be considered additional advantages.

Abstract
OBJECTIVE To identify easily applicable guidelines for the surgical and conservative management of spontaneous cerebellar hematomas. METHODS A treatment protocol was developed and prospectively applied for the management of 50 consecutive cases of cerebellar hematomas. The appearance of the fourth ventricle, adjacent to the hematoma, on computed tomographic scans was divided into three grades (normal, compressed, or completely effaced). The degree of fourth ventricular compression was correlated with the size and volume of the hematoma and the presenting Glasgow Coma Scale (GCS) score. The hematoma was surgically evacuated for all patients with Grade III compression and for patients with Grade II compression when the GCS score deteriorated in the absence of untreated hydrocephalus. Patients with Grade I or II compression were initially treated with only ventricular drainage in the presence of hydrocephalus and clinical deterioration. RESULTS The degree of fourth ventricular compression was classified as Grade I in 6 cases, Grade II in 26, and Grade III in 18. The degree of fourth ventricular compression was significantly correlated with the volume of the hematoma (r(s) = 0.67, P < 0.0001), hydrocephalus (r(s) = 0.44, P = 0.001), the preoperative GCS score (r(s) = 0.43, P = 0.001), the maximal diameter of the hematoma (r(s) = 0.43, P = 0.001), and a midline location of the hematoma (chi(2) = 6.84, P < 0.009). Acute deterioration in GCS scores occurred for 6 (43%) of 14 patients with Grade III ventricular compression who were conscious at presentation. Thirteen patients with Grade I or II ventricular compression and stable GCS scores of more than 13 were treated conservatively. Nine patients were treated with ventricular drainage only, and 28 underwent posterior fossa craniectomy and evacuation of the hematoma with ventricular drainage. The mortality rate at 3 months was 40%. None of the patients with Grade III fourth ventricular compression and GCS scores of less than 8 at the time of treatment experienced good outcomes. Overall, 15 (60%) of 25 patients with hematomas with maximal diameters of more than 3 cm and Grade I or II compression did not require clot evacuation. CONCLUSION Conscious patients with Grade III fourth ventricular compression should undergo urgent clot evacuation before deterioration. Surgical evacuation of the clot may not be required for large hematomas (>3 cm) if the fourth ventricle is not totally obliterated at the level of the clot.

Abstract
BACKGROUND AND PURPOSE The term symptomatic hemorrhage secondary to ischemic stroke implies a clear causal relationship between clinical deterioration and hemorrhagic transformation (HT) regardless of the type of HT. The aim of this study was to assess which type of HT independently affects clinical outcome. METHODS We used the data set of the European Cooperative Acute Stroke Study (ECASS) II for a post hoc analysis. All patients had a control CT scan after 24 to 96 hours or earlier in case of rapid and severe clinical deterioration. HT was categorized according to radiological criteria: hemorrhagic infarction type 1 and type 2 and parenchymal hematoma type 1 and type 2. The clinical course was prospectively documented with the National Institutes of Health Stroke Scale and the modified Rankin Scale: The independent risk of each type of HT was calculated for clinical deterioration at 24 hours and disability and death at 3 months after stroke onset and adjusted for possible confounding factors such as age, severity of stroke syndrome at baseline, and extent of the ischemic lesion on the initial CT. RESULTS Compared with absence of HT, only parenchymal hematoma type 2 was associated with an increased risk for deterioration at 24 hours after stroke onset (adjusted odds ratio, 18; 95% CI, 6 to 56) and for death at 3 months (adjusted odds ratio, 11; 95% CI, 3.7 to 36). All other types of HT did not independently increase the risk of late deterioration. CONCLUSIONS Only parenchymal hematoma type 2 independently causes clinical deterioration and impairs prognosis. It has a distinct radiological feature: it is a dense homogeneous hematoma >30% of the ischemic lesion volume with significant space-occupying effect.

Abstract
BACKGROUND AND PURPOSE Rebleeding is a major cause of death and disability in aneurysmal subarachnoid hemorrhage (SAH); however, there has been no report focusing on rebleeding before hospitalization in neurosurgical or neurological institutions. The aim of this study was to clarify the incidence of prehospitalization rebleeding, its impact on the clinical course and prognosis in patients with aneurysmal SAH, and the possible factors inducing it. METHODS In 273 patients who were admitted to our institution within 24 hours after the initial SAH bleeding and whose clinical course before admission could be fully evaluated, the patients' clinical conditions and CT findings on admission, operability, prognosis, and possible factors inducing rebleeding were comparatively evaluated between the patients with and without an episode of prehospitalization rebleeding. RESULTS Of the 273 patients, 37 (13.6%) patients suffered from 39 episodes of rebleeding in the ambulance or at the referring hospital before admission to our hospital. The peak time of rebleeding was within 2 hours (77%), in which the incidence was statistically significant compared with that occurring 2 to 8 hours after the initial SAH bleeding (P<0.01). The group experiencing rebleeding showed more severe Hunt and Hess grades on admission, higher rates of intracerebral hematoma, of intraventricular hematoma, and of subdural hematoma on CT scan on admission, less operability, and poorer prognoses with statistically significant differences compared with the group that did not experience rebleeding. Systolic arterial pressure >160 mm Hg was a possible risk factor of rebleeding (odds ratio 3.1, 95% CI 1.5 to 6.8). CONCLUSIONS Rebleeding during transfer and at the referring hospital is not rare. To improve overall outcome of aneurysmal SAH, the results obtained in this study should be made available to general practitioners and the doctors devoted to emergency medicine.

Abstract
OBJECTIVES 1) To identify clinical features indicating a high risk of skull fracture (SF) and associated intracranial injury (ICI) in asymptomatic head-injured infants. 2) To develop a clinical decision rule to determine which asymptomatic head-injured infants require head imaging. METHODS We performed a prospective cohort study of all asymptomatic head-injured infants 0-24 months of age presenting to the emergency department of an urban children's hospital. Infants were considered asymptomatic if they had no clinical signs of brain injury, or of basilar or depressed SF. Among subjects who had head imaging, we assessed the utility of age, scalp hematoma size, and scalp hematoma location for predicting SF and ICI. RESULTS Of 422 study patients, 45 (11 %) were diagnosed with SF and 13 (3%) with ICI. In the 172 subjects who had head imaging, there was a stepwise relationship between hematoma size and likelihood of SF. Parietal and temporal hematomas were highly associated with SF; frontal hematomas were not. There was a trend toward higher rates of SF in younger patients. Both large scalp hematoma and parietal hematoma were associated with ICI. Using these data, we developed a clinical decision rule to determine which asymptomatic infants need head imaging. In our study population, this rule has a sensitivity of 0.98 and specificity of 0.49 for SF, and it detects all 13 cases of ICI. The clinical rule calls for imaging in 146/422 (35%) study subjects. CONCLUSIONS Among asymptomatic head-injured infants, the risk of SF and associated ICI is correlated with scalp hematoma size, hematoma location, and weakly with patient age. We propose a clinical decision rule that could identify most cases of SF and ICI while not requiring head imaging for most patients. This decision rule should be validated in other study populations.

Abstract
BACKGROUND Extrapleural hematoma has been found mostly in single case reports as diagnoses with different names. Although huge extrapleural hematoma can cause ventilatory and circulatory disturbances and even death, it has received almost no attention in the literature. Certain basic and modern facts need to be clarified regarding the definition, classification, and significance of extrapleural hematoma in the practice of chest trauma. METHODS A 10-year retrospective study was undertaken to analyze the incidence, diagnosis, management, morbidity, and mortality of patients with chest trauma and a documented extrapleural hematoma. RESULTS The incidence of traumatic extrapleural hematoma was 34 of 477, 7.1%. The incidence of thoracic lesions was 86 of 34 = 2.5 lesions per patient, whereas the incidence of extrathoracic lesions was 30 of 34 = 0.9 lesions per patient. Associated rib fractures were found in 30 of 34, 88.2%. More than half of the patients had an associated hemothorax. A thoracotomy was used successfully to remove a huge hematoma in one patient. CONCLUSION Extrapleural hematoma has been found to be more common than previously reported. Nomenclature and classification are suggested. One of the common injuries to the chest, particularly rib fracture, hemothorax, lung contusion, or pneumothorax might provide the surgeon with a reliable clinical clue that the patient is at inordinate risk to have associated extrapleural hematoma. A formal or mini-thoracotomy is the recommended procedure in cases of huge hematomas.

Abstract
Hematoma development following procedures involving femoral arterial puncture is a potentially serious complication, estimated to occur in 0.6% to 17% of the population undergoing these procedures. (Karfonta, 1994). A review of the current literature indicates there is a lack of consistent recording mechanisms and a lack of descriptors to document femoral site observations. Our purpose is to demonstrate the utility of a Hematoma Classification Tool (developed and piloted at the University of Ottawa Heart Institute) for post operative care management of patients following femoral arterial puncture.

Abstract
Minutes can make the difference between life and death when patients with severe head injuries require surgery. Subdural, epidural, and intracerebral hematomas and cerebral contusions and gunshot wounds are the pathologic entities encountered most frequently during emergency surgery in patients with severe head injuries. Neurosurgical team members frequently use hyperventilation, mannitol and barbiturates, and sophisticated monitoring modalities to manage patients with severe head injuries during and after surgery. Although monitoring a patient's intracranial pressure (ICP) through a ventriculostomy catheter remains the most widely used gauge of cerebral metabolism, neurosurgical teams also are using fiber-optic ICP monitoring catheters, cerebral blood flow measurement probes, microdialysis catheters, jugular venous oxygen saturation catheters, and brain oxygen content measurement electrodes. Coordinated teamwork by perioperative nurses, neurosurgeons, anesthesia care providers, and emergency department staff members helps ensure the best possible outcomes for patients who require surgery for management of severe head injuries.

Abstract
A method of classification for hematomas of the rectus abdominis sheath (RSH) is proposed based on findings observed in CT in the 13 cases of RSH in the present study. Type I hematomas (five cases) are slight and do not require hospitalization. Type II (three cases) and type III (five cases) are moderate and severe hematomas, respectively, and do require hospitalization. The patients with type III hematomas were all undergoing anticoagulant therapy and presented with a picture of acute abdomen, and in all five cases blood transfusion was carried out. Ultrasonography and, in particular, CT permitted a correct diagnosis of RSH. RSH should be considered (anticoagulant therapy induced) in females with sudden abdominal pain to avoid unnecessary surgical intervention.

Abstract
It is not easy to predict functional outcome in patients with acute-stage thalamic hemorrhage. We analysed 100 cases of hypertensive thalamic hemorrhage less than 4 cm in diameter, and devised a practical CT classification for predicting the patients' prognoses. On an axial CT scan at the level of the pineal body, four lines were drawn as follows: line (a) between the lateral edge of the anterior horn and the midpoint of the third ventricle; line (b) vertical line to the sagittal line from the midpoint of the third ventricle; line (c) between the lateral edge of the trigone and the midpoint of the third ventricle; line (d) between the lateral edge of the anterior horn and the lateral edge of the trigone. The location of hematoma was divided into three types according to lateral extension as follows: type A (anterior type), center of hematoma located between line (a) and line (b); type P (posterior type), center of hematoma located between line (b) and line (c), and external margin of hematoma localized medial to line (d); type PL (postero-lateral type), center of hematoma located between line (b) and line (c), and showing lateral extension beyond line (d). Then, the correlation between hematoma location and severity of motor paresis at onset and its prognosis was investigated. Severe hemiparesis (MMT: 0-2) was observed in 15.3% of patients with type A, 21.8% with type P, and 59.3% with type PL hematoma in the acute stage.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Authors perform a retrospective review of all hepatic injuries operated on between 1974 and 1990 at Clinica Chirurgica II (ex Patologia Chirurgica II, ex Semeiotica Chirurgica) of Policlinico San Matteo (IRCCS) of Pavia. Thirteen patients were treated, 9 men and 4 women, with age ranged from 13 to 68 years and a mean age of 38 years. They were 21% of all patients operated on for abdominal trauma. Penetrating wounds were present in only two cases (15%), the other patients (85%) were affected by blunt trauma. The mechanisms of injuries were: road accidents (77%), fall at work (8%), gun shot wound (8%), stab wound (8%). All patients had associated injuries. The mortality was 31%: one patient died for haemorrhagic shock and the other three for craniocerebral injuries. After reviewing the several haemostatic techniques advocated for the various types of hepatic injuries, the authors stress that, although most lesions are minor and can be managed by simple technique of haemostasis, often the prognosis is severe for the associated injuries.

Abstract
The article deals with the analysis of the clinical and computed tomography data, treatment, and outcomes in 94 patients with traumatic intracerebral hematomas (TICH). The indications for nonoperative treatment of TICH are a level of consciousness of the patient of no lower than 10 marks of the Glasgow coma scale, hematoma diameter of less than 4 cm, and the absence of clinical and computed tomography signs of brain stem compression. Osteoplastic trephination and encephalotomy is the principal surgical method. Puncture evacuation of the TICH may be resorted to if more than three fourths of its volume can be aspirated. The stereotaxic method is recommended for removal of TICH situated in the region of the basal ganglia.

Abstract
The medical examination of presumed victims of sexual assault can be important evidence in criminal cases, hence, its documentation has to be conducted very carefully. A thorough physical examination must always include a search for the marks of brute force or strangulation. The correct preservation of body fluids and swabs is essential, especially since new DNA "finger-printing" techniques ("genetic fingerprinting") may accomplish identification of the offender.

Abstract
Clinical and intraoperative evidences of closed scrotal and testicular injuries were correlated in 119 out of 171 treated patients. On the basis of clinical and anatomical signs the authors developed the classification of the aforementioned injuries distinguishing between the isolated scrotal and testicular ones. In 80.9 per cent of the patients operated on for the testicular injuries the patterns of the trauma were identified as the ruptures, contusions, or intratesticular hematomas. With regard to the clinical signs the classification permitted one to diagnose isolated injuries of the scrotum, the ruptures of the testis or intratesticular hematomas. Regardless of the extent of the trauma (testicular ruptures or intratesticular hematomas) histological studies revealed hemorrhagic infiltrations, vascular thromboses and dystrophic changes of the tubular epithelium only in the hours immediately after the accident. The authors documented the early development of suppuration and sclerosis of the compromised organ. The conservative treatment was found to be advisable only for the patients with isolated scrotal injuries and small hematomas in tunica dartos. Large hematomas in tunica dartos, testicular ruptures or intratesticular hematomas necessitated the performance of emergency organ-sparing surgeries with the use of anticoagulants, antibiotics and anti-inflammatory drugs. The above treatment policy was a success in 65 per cent of these treated.

Abstract
A retrospective analysis of our series of 355 cases of putaminal hemorrhage revealed some interesting aspects of its pathogenesis. All the cases were studied in detail with special attention to clinical presentation, diagnostic findings and the long-term clinical outcome. Role of surgery in management of putaminal hemorrhage is still controversial. Inability to form proper useful classification has been one of the reasons responsible for this controversy. A new classification is formulated which divides putaminal hemorrhage into four types. Mild type has hematoma localized to external capsule while moderate type shows hematoma extension to corona radiata from external capsule. In severe type, hematoma extends to internal capsule also while in very severe type it further extends to midbrain. These four types could be very well correlated to long-term clinical outcome. Accessory hematoma is discussed in detail. It is found to be more common in severe and very severe types. Its presence in mild or moderate types results in worse clinical outcome. Hypertension (BP greater than 200 mm of Hg) may play an important role in further extension of hematoma.

Abstract
We determined the profile of behavioral disturbance in relation to closed head injury of graded severity. Patients with severe injuries, as defined by duration of coma and the presence of neurological deficit, were differentiated from a group of mildly injured patients by behavioral ratings that reflected cognitive disorganization, emotional withdrawal, and motor retardation. Neurologic measurements of injury related to the severity of behavioral disturbance included hemiparesis, aphasia, and abnormalities on computerized axial tomography. Agitation during the acute phase of injury was also predictive of residual behavioral disturbance. Hemispheric lateralization of the site of greatest injury had no discernible effect on behavioral sequelae.
