ABSTRACT

We devised IMADOKO as a tool to confirm the current status of terminal cancer patients and are using it in the home care team. In this study, we retrospectively investigated the actual state of end-of-life care to clarify the impact of IMADOKO on decision-making support for terminal cancer patients and their families. The subjects were 64patients (male/female, 38/26) before IMADOKO introduction, and 140 patients (male/female, 78/62) after the introduction, with an average age of 74 years in both cases and the primary lesions were the pancreas, lung, and the gastrointestinal tract. The rate of death at home increased significantly after the introduction of IMADOKO, compared to before. In the IMADOKO introduced group, IMADOKO was used in 108 patients and all their families. The use of IMADOKO for the patient was not related to the location of death, but it significantly improved communication between the patient and family, and between patient/patient's family and medical staff. It was shown that IMADOKO may be useful for decision-making support in choosing a better place of recuperation.

ABSTRACT

OBJECTIVE: The purpose of the present study was to clarify the relationship between white matter tracts and cognitive symptoms in children with high-functioning autism spectrum disorder (ASD). METHODS: We examined the cognitive functions of 17 children with high-functioning ASD and 18 typically developing (TD) controls and performed diffusion tensor imaging (DTI) tractography. We compared the results between the groups and investigated the correlations between the cognitive scores and DTI parameters within each group. RESULTS: The Comprehension scores in the ASD group exhibited a positive correlation with mean diffusivity (MD) in the forceps minor (F minor). In the TD group, the Comprehension scores were positively correlated with fractional anisotropy (FA) in the right inferior fronto-occipital fasciculus (IFO) and left anterior thalamic radiation (ATR), and negatively correlated with MD in the left ATR, radial diffusivity (RD) in the right IFO, and RD in the left ATR. Additionally, a positive correlation was observed between the Matching Numbers scores and MD in the left uncinate fasciculus and F minor, and RD in the F minor. Furthermore, the Sentence Questions scores exhibited a positive correlation with RD in the right inferior longitudinal fasciculus. Relative to TD controls, the specific tract showing a strong correlation with the cognitive scores was reduced in the ASD group. CONCLUSION: Our findings indicate that white matter tracts connecting specific brain areas may exhibit a weaker relationship with cognitive functions in children with ASD, resulting in less efficient cognitive pathways than those observed in TD children.

ABSTRACT

A number of patients with ischemic cerebrovascular stroke suffer a progressive deterioration secondary to massive cerebral ischemia, oedema, and increased intracranial pressure [ICP]. The evolution is often fatal. Stroke is the second leading cause of death worldwide. Life-threatening, complete middle cerebral artery [MCA] infarction occurs in up to 10% of all stroke patients, and this may be characterized as massive hemispheric or malignant space-occupying supratentorial infracts[35-50] Malignant, space-occupying supratentorial ischemic stroke is characterized by mortality up to 80%, several reports indicated a beneficial effect of hemicraniectomy in this situation, converting the closed, rigid cranial vault into a semi open. The main cause of death encountered in these patients is severe postischemic brain oedema leading to raised ICP, clinical deterioration, coma, and death [20-44]. The result is dramatic decrease in ICP and a reversal of the clinical and radiological signs of hemiation. For these reasons, decompressive craniectomy has been increasingly proposed as a life-saving measure in patients with large, space-occupying hemispheric infarction. Recent successes with intra-venous [52] and intra-arterial[11] thrombolytic therapy have resulted in an increased awareness of stroke as a medical emergency[52] Thus, increasing numbers of patients are being evaluated in the early hours following the ictal event. In the process of gaining more experience in the early management of patients with acute ischemic stroke, it has become clear that in a number of these patients a progressive and often fetal deterioration secondary to mass effect from the oedematous, infarcted tissue occurs. An increasing body of experimental and clinical evidence suggests that some of these patients may benefit from undergoing a decompressive craniectomy but the timing and indications for this potential lifesaving procedure are still debated. Early hemicraniectomy based on radiographic and clinical criteria, but before signs of brainstem hemiation, has been proposed as a means of improving outcomes. The objectives of the review are to help better define the selection criteria for performing the surgery in case of supratentorial infarctions, to asses the immediate outcome in terms of time conscious recovery and survival and to assess long term outcome using standard and functional assessment scales

ABSTRACT

Aneurysm clips of different shapes, sizes, fenestrated or non fenestrated can be applied for reconstruction of the arteries in cases of wide necked aneurysms. By fashioning different clips and applying them to the aneurysmal neck in patients with wide necked aneurysms, we describe the method of approximation of the inner walls of the neck of the aneurysm extending to the parent artery leading to complete exclusion of the aneurysm from the circulation. This method also confirms the approximation of the intimae on both the sides of the neck. After exposing the aneurysm, its parent artery and the perforators, the aneurysm neck is carefully dissected; the perforating arteries are also carefully dissected away. Appropriate clip selection is made and clip is applied to the neck of the aneurysm so that the walls of aneurysm which extend into the parent artery are also approximated, thus no remnant of the aneurysm is left behind, in the part extending into the parent vessel. Repeat angiograms done after 3 months of surgery showed no regrowth, or incomplete occlusion of the aneurysm. This method of clip application avoids any recurrence or regrowth of the aneurysm. The greatest advantage of this method of the clip occlusion is that it takes care of the part of the aneurysm which extends into the parent artery, so that even the minimal possibility of any aneurysmal remnant is ruled out

ABSTRACT

Pericallosal artery aneurysms comprise about 1.5 to 9% of all intracranial aneurysms. Some of them are caused by head injury. We report a 66-year-old male patient with ruptured left pericallosal artery aneurysm, 2.6 x 3.2 mm in size. The patient fell 2 months ago. Operation was done under right interhemispheric approach. The parent artery was avulsed while the clip was adjusted. The avulsed part was sutured and postoperative CAG revealed totally obliteration of the aneurysm while the repaired artery was patent. The patient recovered well after operation

ABSTRACT

The cavum veli interpositi is not a rare ventricular anomaly, however it is usually asymptomatic. A case of primary haemorrhage in the cavum veli interpositi as the bleeding source of intraventricular haemorrhage, without vascular lesion or tumour, was diagnosed and treated by neuroendoscopic surgery. A 17-year-old woman with history of transient visual field loss 2 years ago had sudden onset of headache followed by vomiting. A head CT scan showed intraventricular haemorrhage with predominant haematoma in the cavum veli interpositi. A diagnostic angiography demonstrated no apparent vascular lesion, however remarkably delayed appearance of deep venous system and the straight sinus, with prominent collateral drainage toward the vein of Labbe was noted. An external ventricular drainage was placed immediately, followed by endoscopic removal of intraventricular haemorrhage excluding the haematoma in the cavum veli interpositi on day 3. The left internal cerebral vein was engorged and seemed to be congestive during surgery. The postoperative course showed good recovery without neurological deficit. An angiography was repeated 23 days after the onset and it demonstrated improved venous circulation. This is the first report on a primary haemorrhage in the cavum veli interpositi. The cause of bleeding was unknown however, possible abnormal vascular anatomy in this anomalous space might be associated. The vein of Galen is shifted downward by the cavum veli interpositi and this might cause venous hypertension in the deep venous system. Improvement of the venous circulation on the angiography suggested compression of the veins by haematoma can cause impairment of blood circulation and this fact supports theoretical benefit of haematoma removal. Effectiveness of endoscopic treatment for intraventricular haemorrhage is discussed

ABSTRACT

The meninges [dura mater, arachnoid, pia mater] are the site of numerous pathological lesions including inflammation and neoplasm Meningiomas are the most frequently observed lesions and the most common of primary meningeal tumours. Over the years, meningiomas has been histologically classified and some entities have been added to the cadre of meningioma variants, while others have been designated as other types of tumours. The 200 revision of the World Health Organisation [WHO] grading system provided diagnostic guidelines. Most meningiomas are biologically benign and correspond to the WHO grade. However, certain meningiomas have an increased tendency to recur or follow an aggressive clinical behavior and are assigned an WHO grade and have a substantially increased incidence of recurrence. Rhabdoid meningioma, papillary meningioma and anaplastic meningioma corresponding to WHO grade have an even higher incidence of recurrence and may be associate with systemic metastasis or brain invasion. There is some information regarding the nature of mental deficits caused by intracranial meningiomas. In this study the authors examined the mental functioning of patients with frontal meningiomas. Twenty-one patients with frontal meningiomas were examined for various neurological symptoms after surgery. Observed neurological symptoms were memory deficits [verbal and fungal], attention and executive functions. The time period between onset of the effect on mental functions of meningioma and postoperative observations ranged from 2-3 months. Postoperative findings revealed a few or no differences in memory or executive functions, although, a postoperative improvement in attentional function was observed. The results of the study indicate that the surgical removal of frontal meningiomas does not impair patients' mental functioning

ABSTRACT

Most of the aneurysms can be treated successfully with either surgery or endovascular modality alone. But, some complex aneurysms can be better managed with surgical and endovascular combined modality of treatment. This study was done to review combination options, their indications and outcome. Articles in English literature on surgical and endovascular combined modality of treatment for cerebral aneurysms were reviewed and analyzed based on Pubmed search. Followed combination options were used: Surgery followed endovascular therapy: 1. Extracranial to intracranial bypass surgery followed by endovascular parent vessel occlusion. 2. Aneurysm clipping assisted by temporary balloon occlusion with/without suction decompression. 3. Intentional partial clipping for neck reconstruction followed by endovascular aneurysm packing. 4. Clipping as the first treatment. Regrown or partially clipped aneurysm obliterated by endovascular packing. Endovascular therapy followed by surgery: 1. Partial coiling to prevent rebleed followed by delayed definitive clipping. 2. Permanent parent vessel occlusion followed by surgery for decompression in giant aneurysm. 3. Coiling as the first treatment, reanalyzed aneurysm treated with clipping. 4. Coiling and clipping of multiple remote aneurysms. In various published series; combined modality of treatment has shown better results in complex aneurysms as compared to either of the modality alone with less morbidity. Surgical and endovascular combined modality is very useful addition to the armamentarium for the management of complex aneurysms and can be applied in various combinations. When used rationally, this approach offers the best outcome with reduction of treatment morbidity

ABSTRACT

Trigeminal neuralgia, like other rhizopathies, has defied categorization, clarification in pathology and effective treatment, despite several efforts, in several disciplines. The different rhizopathies like trigeminal neuralgia, hemifacial spasm, glossopharyngeal neuralgia, tinnitus, spasmodic torticollis, etc., all share a common pathology i.e., a vascular compression of the cranial nerve at the root entry zone. A comprehensive description of the features of trigeminal neuralgia and the surgical management with microvascular decompression is detailed in this article. Microvascular decompression is a relatively safe surgery and complications are very unlikely in dexterous hands

ABSTRACT

The goals of surgical treatment of intracranial aneurysms are to occlude the lesion and maintain blood flow in parent, branching and perforating vessels. We report our experiences in 3 cases using this method for intraoperative blood flow assessment, detection of incomplete clipping of aneurysm and to assess image quality and evaluate the clinical value of this method. A special arrangement of the filters was designed to allow the passage of near-infrared light required for the excitation of the indocyanine green [ICG] fluorescence [700 - 850 nm] from a modified microscope light source into the surgical field and the passage of ICG fluorescence [780 - 950 nm] from the surgical filed back into the optical path of the surgical microscope [Carl Zeiss, Oberkochen, Germany]. Thus, the ICG angiography could be completely performed with a surgical microscope. The reported 3 cases, one female and 2 male, either with incomplete or inadvertent clipping of the branching vessels of unruptured aneurysms were performed using ICG which was excellent in detection of incomplete or inadvertent clipping of the branching vessels

ABSTRACT

To evaluate the usefulness of endoscope during anterior circulation cerebral aneurysm surgery. From June 2004 to June 2005, endoscope was applied in 83 aneurysms of anterior circulation cerebral aneurysm surgeries. There was no mortality in our series and no new neurological deficits occurred after surgery. One aneurysm ruptured during the microsurgical dissection, which was not related to endoscope manipulation. Endoscope provided new information in 28 aneurysms. The clips were re-adjusted in 10 cases after endoscopic examination. Endoscope is useful during anterior circulation cerebral aneurysm surgery. It can provide valuable information which is not available from microscope, it is useful both before and after clipping. Most importantly, it provides information regarding the completeness of neck obliteration and the preservation of important perforators

ABSTRACT

Distal anterior cerebral artery [ACA] aneurysms are rare and compose less than 5% of all intracranial aneurysms. Most of the aneurysms in this location are congenital, saccular ones, but it is also a well-known location for traumatic aneurysm. The mechanism of aneurysm development, clinical scenario and/or surgical difficulty are different between these two groups. Between March 2005 to February 2006, 6 cases of distal ACA aneurysms were treated at the Department of Neurosurgery, Fujita Health University, Aichi Prefecture, Japan. The clinical presentations, neurological findings, and treatment were analyzed. Of 6 patients, 2 were male and 4 were female, aged from 66-79 years. Of 6 cases, one was traumatic aneurysm, which occurred 2 months after a fall injury. Of the 5 congenital aneurysms, one was unruptured, the other 4 were all ruptured. One patient had multiple aneurysms. We believe that there are differences between the congenital and traumatic aneurysms in respect to the mechanism of development, aneurysm location, and treatment difficulties

ABSTRACT

Anterior petrosal approach [Kawase's approach] is an established technique for the management of basilar artery aneurysms arising near the origin of anterior inferior cerebellar artery [Ba-AICA], however the extent of petrosectomy may vary from patient to patient. Authors report their experience with Kawase's approach for the management of these aneurysms in 5 patients. During the last 10 years, anterior petrosal approach was used to clip aneurysms of Ba-AICA junction in five patients, who were not suitable for endovascular therapy. Both ruptured and unruptured aneurysms were included in this series. Successful clipping could be achieved in all but one patient. In this patient with a large aneurysm and complex morphology, residual filling was noted in the postoperative angiogram. Postoperatively one patient developed hemiparesis and transient sixth nerve palsy. There was no operative mortality in this series. For patients with small Ba-AICA shoulder aneurysms, where clipping is preferred method of treatment, sufficient exposure is achieved through Kawase approach, however minor variation may be required while resecting the petrous bone

ABSTRACT

Anterior internal carotid artery aneurysm is a rare kind of aneurysm caused by atherosclerosis. This paper summarises the authors' experience with this kind of rare aneurysm. From January 2001 to December 2004, 6 cases of anterior internal carotid artery aneurysms were treated at Fujita Health University Hospital. The patients' clinical presentation, image data, treatment and outcome are described. Through the authors' limited number of cases, we concluded that all the aneurysms were located at the supraclinoid portion of the internal carotid artery. Two of our cases did not have arteriosclerosis. We used clipping and wrapping techniques to manage these easily ruptured aneurysms

ABSTRACT

Objective To investigate the accuracy of electrocardiogram(ECG)-gated CT angiography in the detection of bleb in unruptured aneurysm. Methods In 2004,15 unruptured aneurysm patients received ECGgated CT angiography examination. Results Ten of the patients had bleb and the bleb was detected as the pulsation site in ECG-gated CT angiogram.Surgically excised specimen were stained and histological investigation revealed that there were partial or complete absence of tunica media smooth muscle and the internal elastic lamina layer in the aneurysm wall in 15 cases.A sudden reduction of collagen layer was noted in 10 cases with bleb.(Conclusion)ECG-gated CT angiography can be used in the bleb detection of unruptured aneurysms,and its accuracy can be verified by histological examination.
