Clinical effects of neuroendoscopic infratentorial supracerebellar approach surgical technique for resecting pineal tumors: a retrospective study

ObjectivePineal tumors are relatively rare central nervous system lesions with a predilection for the pediatric population. This article aims to explore the clinical effects of neuroendoscopic infratentorial supracerebellar approach for resecting tumors in the pineal area. MethodsThis is a retrospective study that included patients who underwent neuroendoscopic infratentorial supracerebellar approach to resect nine tumors in the pineal area at the Department of Neurosurgery of the Second Hospital of Lanzhou University from December 2017 to October 2023. ResultsThe results of postoperative MRI revealed that all tumors were resected. Five patients received postoperative radiotherapy, three patients received radiotherapy along with chemotherapy, and one patient received neither radiotherapy nor chemotherapy. The pathological results showed that four patients were diagnosed with germinoma, two patients with teratoma, two patients with mixed germ cell tumors, and one patient with central neurocytoma. After surgery, one patient developed psychiatric symptoms, two patients developed binocular upward vision and diplopia, and one patient developed unstable walking and diplopia. With a follow-up of 1.7–4.8 years, all nine patients lived normally. Furthermore, none of them had tumor recurrence or death. ConclusionThe simple neuroendoscopic infratentorial supracerebellar approach has some safety and efficacy. It is suitable for tumors in the pineal region where the disease is mainly located below the Galen vein complex.

Primary intraventricular hemorrhage caused by Galen vein thrombosis in an elderly patient: A case report

AbstractA 79‐year‐old man with a history of hypertension, type 2 diabetes, vasospastic angina, and an abdominal aortic aneurysm was transferred to our hospital with headache and anorexia 3 days prior to presentation. Brain computed tomography (CT) revealed left‐dominant intraventricular hemorrhage (IVH). T2*‐weighted magnetic resonance imaging and magnetic resonance venography revealed a low‐intensity lesion and a deficit, respectively, inside the vein of Galen, leading to the diagnosis of Galen vein thrombosis. Anticoagulants were administered. Consequently, his symptoms resolved, and brain CT revealed improvement in the IVH. Magnetic resonance venography confirmed the recanalization of the vein of Galen. Cerebral venous thrombosis (CVT), including Galen vein thrombosis, can cause primary IVH. In cases of primary IVH of unknown etiology, even in elderly patients, clinicians should suspect CVT and magnetic resonance imaging should be performed.

BackgroundDural arteriovenous fistulas (dAVFs) draining into the vein of Galen (VoG) are complex lesions that often necessitate treatment to minimize the risk of rupture and relieve symptoms. These lesions can...

De novo formation of a giant dural arteriovenous fistula after cerebral venous sinus thrombosis

A 45-year-old male patient with past medical history of obesity and diabetes presented with complaints of pulsatile, frontal headache evolving in the past two days. His vital signs were normal and he had no meningeal signs or neurologic deficits. Magnetic resonance angiography (MRA) revealed cerebral venous sinus thrombosis (CVST) with intraluminal thrombus in galen's vein, and right rectum and transverse sinuses

Unexpected CT Scan Discovery of a Giant Galen Vein Aneurysm in An Infant: A Rare Case Report

Aneurysmal malformation of the Galen vein is an uncommon abnormality, comprising less than 1% of all congenital cerebral vascular malformations. However, it accounts for approximately 30% of such malformations in the pediatric population. This condition represents a cerebral arteriovenous malformation that develops prenatally, initiating prior to ten weeks of gestation. It arises from the formation of arteriovenous fistulas connecting the choroidal circulation and the median prosencephalic vein, an embryonic precursor of the Galen vein, which subsequently undergoes dilation. Here, we present an exceptional case of this malformation that was incidentally detected during a Brain CT scan.

Aural Arteriovenous Fistulas Presenting as Symmetric Lesions in the Internal Capsule on Imaging Studies: A Case Report and Literature Review.

Dural arteriovenous fistulas (DAVFs) leading to oedema, primarily in the internal capsule, are extremely rare and, to our knowledge, have never been reported. We reported a case of DAVFs with oedema in bilateral internal capsule oedema and reviewed the literature. The report describes a unique imaging presentation of cases of DAVFs as symmetric lesions, mainly in the bilateral internal capsule. It also reviews the literature for symmetric lesions in the internal capsule and central grey matter caused by DAVFs to further characterize this rare entity and differential diagnosis through imaging features. In cases of symmetric oedema caused by DAVFs, the most common artery involved in arterial supply was the middle meningeal artery (13/24; 54%). The main vein involved in the drainage was the Galen vein (18/29; 62%). Most cases were treated with transarterial embolization (23/29; 79%), and the probability of effective treatment or complete cure is 100%. On imaging, the vasogenic oedema signal caused by DAVFs is a symmetrical lesion of the bilateral internal capsule, that is, DWI MRI shows a high signal in the unrestricted diffusion area on the apparent diffusion coefficient map. MR has good diagnostic value in abnormal basal ganglia symmetric signals caused by DAVFs, and can quickly identify DAVFs early.

A VEIN OF GALEN MALFORMATION - A RARE CAUSE OF CONGESTIVE CARDIAC FAILURE IN NEONATE

Vein of Galen aneurysmal malformation (VGAM) is a rare congenital vascular malformation caused by the maldevelopment of its embryonic precursor, the median prosencephalic vein of Markowski. Vein of Galen aneurysmal malformation (VGAM) is a rare cause of congestive heart failure in the neonatal period and carries a high mortality rate. It is a difcult diagnosis because the clinical picture often presents with symptoms suggesting that the patient has a congenital cardiac malformation.1,2 Patients are subjected to high-risk procedures such as cardiac catheterization to establish a diagnosis. These investigations often have negative ndings and can delay correct diagnosis. Here we report a case of Four days old neonate with c/o Increased respiratory activity since 2 days with tachycardia, tachypnea and oliguria. Continuous murmur was noted with features suggestive of Congestive cardiac failure i.e. Tachycardia, tachypnoea, hepatomegaly. Bruit + over Anterior Fontanelle. USG skull revealed the presence of Vein of Gallen Aneurysmal Malformation. 2D ECHO was done which suggestive of Congenital Heart Disease; moderate OS ASD with left to right shunt Dilated cardiac chambers; No PAH; Normal biventricular function .CECT Brain showed the presence of Aneurysmal deep venous structure measuring 20 x 25 mm noted in the supratentorial region of posterior fossa (in quadrigeminal cistern) which drained to vein of galen (VGAM) and the vessel feeding the aneurysm was arising from basilar artery.Hence diagnosis was made.Child initially treated symptomatically for cardiac failure then Endovascular treatment i.e. embolization was performed on 30th day of life.The VGAM was partially occluded.Then symptoms got relieved after Embolization

Galen's Ampulla Aneurysm: A Case Report

Introduction: Galen's vein aneurysm is a rare complex intracranial arteriovenous malformation, associating pseudo-aneurysmal dilation of Galen's ampulla with one or more arteriovenous fistulas. The prognosis is often poor, with high mortality and a risk of neurological sequelae. Objective: To support the role of imaging in the diagnosis, with illustration by two observations collected within our Radiopediatrics department of the CHU Mohammed VI of Marrakech, having benefited from a cerebral angio-scanner. Case Report: 1st case:is an 18-month-old infant with no particular history presenting macrocrania with generalized seizures.2nd case:is also a 2-year-old infant, with the appearance of a vein in the suborbital groove for 6 months, with no other associated signs.3rd patientis a 1-year-old infant with macrocrania with signs of HTIC. 4th case6-month-old boy, presents with HTIC syndrome. Objective cerebral CT in the first three patients: a rounded median mass, in the pineal region behind the 3rd ventricle, slightly hyperdense in spontaneous contrast; CT angiography proves the vascular nature of the lesion by showing intense and homogeneous enhancement after injection of PDC, associated with dilation of the venous sinuses, and moderate passive triventricular hydrocephalus by compression of the aqueduct of Sylvius. The fourth patient benefited from a transfontanellar ultrasound which objectified an anechoic interhemispheric fusiform structure presenting a vascular flow to the color Doppler. Conclusion: The aneurysmal malformation of the Vein of Galen (AVGM) is a rare vascular malformation, specific to children, discovered ante or post natally, in fact only corresponds to a venous dilation draining an arterio-venous malformation, whose system afferent arterial comes from the carotid system or the vertebro-basilar axis; it results from the absence of differentiation in the mature arterio-venous system, between 7 and 12 SA, of a primitive, median embryonic vein which ......

Abstract Number ‐ 114: Deep Cerebral Venous Thrombosis requiring Venous Thrombectomy and Intra‐arterial Thrombolysis in Young Pregnant Female

Introduction Cerebral venous sinus thrombosis (CVST) is a rare cause of stroke and mortality especially in young women and children (1). Even though, first‐line treatment remains anticoagulation, some patients deteriorate and endovascular treatment is needed. Currently there are no randomized controlled trials comparing the efficacy and safety of intracranial thrombolysis and mechanical thrombectomy to standard‐of‐care anticoagulation therapy (2). We present a case of a pregnant lady with CVST with successful clinical outcomes with venous thrombectomy and intraarterial thrombolysis. Methods Case Report Results 30 year old lady with no past medical history, 7 weeks and 4 days pregnant presented with acute progressive encephalopathy associated with nausea, vomiting and headaches. On admission, she was stuporous, had dysarthria, severe hemiparesis, and hemineglect on the right side. She had COVID‐19 infection and her fetus had subchorionic hematoma by ultrasound. Initial CT brain showed extensive cerebral venous sinus thrombosis (CVST). She was intubated and MRI showed venous infarcts. MR venography revealed acute extensive CVST of superior sagittal sinus, vein of galen, right transverse sinus, right sigmoid sinus, and right jugular vein. IV Heparin drip was initiated. Her follow‐up neurological exam deteriorated despite maximal medical therapy. The decision was made for endovascular recanalization. The cerebral angiogram confirmed the occlusion of deep venous system. Thrombectomy of bilateral internal jugular vein and sigmoid sinus was performed with retrieval of thrombi. Post‐thrombectomy runs demonstrated persistent extensive CVST and decision was made for intra‐arterial thrombolysis. A diagnostic catheter was secured in the right internal carotid artery catheter (ICA). Thombolysis was performed with 4 mg/hr recombinant tissue‐plasminogen activator (rt‐PA). Heparin drip IV was continued. Subsequently, the repeat CT brain showed significant improvement in the CVST and interval development of intraparenchymal hemorrhages and subarachnoid hemorrhages. Heparin and rt‐PA were held. The patient was found to have Factor V Leiden mutation and she was started on Enoxaparin 1mg/kg throughout her pregnancy and 6 weeks postpartum. Clinically she demonstrated significant neurologic improvement and was discharged to home from rehabilitation center. Currently, she is thirty‐ four weeks pregnant and neurologically intact without any deficits. Conclusions Pharmacological and mechanical endovascular interventions can have significantly successful clinical outcomes in deep cerebral venous thrombosis. Controlled studies are required to assess the safety and efficacy of these interventions when compared to standard systemic anticoagulation.

Non-contrast assessment of blood-brain barrier permeability to water in mice: An arterial spin labeling study at cerebral veins

Blood-brain barrier (BBB) plays a critical role in protecting the brain from toxins and pathogens. However, in vivo tools to assess BBB permeability are scarce and often require the use of exogenous contrast agents. In this study, we aimed to develop a non-contrast arterial-spin-labeling (ASL) based MRI technique to estimate BBB permeability to water in mice. By determining the relative fraction of labeled water spins that were exchanged into the brain tissue as opposed to those that remained in the cerebral veins, we estimated indices of global BBB permeability to water including water extraction fraction (E) and permeability surface-area product (PS). First, using multiple post-labeling delay ASL experiments, we estimated the bolus arrival time (BAT) of the labeled spins to reach the great vein of Galen (VG) to be 691.2 ± 14.5 ms (N = 5). Next, we investigated the dependence of the VG ASL signal on labeling duration and identified an optimal imaging protocol with a labeling duration of 1200 ms and a PLD of 100 ms. Quantitative E and PS values in wild-type mice were found to be 59.9 ± 3.2% and 260.9 ± 18.9 ml/100 g/min, respectively. In contrast, mice with Huntington's disease (HD) revealed a significantly higher E (69.7 ± 2.4%, P = 0.026) and PS (318.1 ± 17.1 ml/100 g/min, P = 0.040), suggesting BBB breakdown in this mouse model. Reproducibility studies revealed a coefficient-of-variation (CoV) of 4.9 ± 1.7% and 6.1 ± 1.2% for E and PS, respectively. The proposed method may open new avenues for preclinical research on pathophysiological mechanisms of brain diseases and therapeutic trials in animal models.

Aneurysmal dilatation of vein of galen associated with thalamic arteriovenous malformation and straight sinus agenesis

Straight sinus agenesis is a rare congenital anatomical variation that is usually accompanied by persistent falcine sinus. Concomitance of straight sinus agenesis and absence of falcine sinus are associated with thalamic arteriovenous malformation by the disturbance of the venous flow. In this report, a very rare case of aneurysmal dilatation of the vein of Galen associated with thalamic arteriovenous malformation and straight sinus agenesis is presented.

Three underdogs among galenic veins: anatomical analysis and literature review of surgical relevant veins in the quadrigeminal cistern.

Recent studies (Alaou-Ismaili et al. 2020; Kilic et al. Eur J Radiol 56:212-219, 2005) among experienced sub-specialized neurosurgeons described divergent perceptions of surgical risk for venous sacrifice in posterior fossa surgery. Three galenic veins stood out as controversial in venous risk assessment and underexplored in the literature: the internal occipital vein (IOV), the precentral cerebellar vein (PCV), and the superior vermian vein (SVV). We have conducted a narrative review based on a systematic literature search to analyze terminology and anatomic descriptions and to suggest a coherent synthesis of published data on these veins. A systematic PubMed literature search was carried out using the keywords: "posterior fossa," "venous anatomy," and "radiology." Relevant radiological, microsurgical, and anatomical articles were selected if they described the anatomy of the three veins. Anatomical descriptions were analyzed with hermeneutic methodology alongside the articles' radiological and anatomical dissection pictures. New illustrations were created to depict the synthesized image of the venous anatomy. A total of 13 articles described the anatomy and terminology of the relevant veins. The descriptions of the IOV included smaller non-occipital vessels that confused the identification of the vessel. IOV is analyzed to be the vein draining the primary visual cortex, which drains into the vein of Galen (VG). The PCV and SVV enter the VG from below and are fused in almost half of all studied patients, creating a third vessel by the name of the superior cerebellar vein. A conscientious narrative review and hermeneutic analysis produced a synthesized, uniform picture of terminology and anatomy. Consensus on anatomical descriptions and definitions are indispensable for validation of anatomy, research into anatomical variation, for surgical planning and documentation.

Utility of indocyanine green videoangiography with FLOW 800 analysis in brain tumour resection as a venous protection technique

BackgroundIn regard to central nervous system tumour resection, preserving vital venous structures to avoid devastating consequences such as brain oedema and haemorrhage is important. However, in clinical practice, it is difficult to obtain clear and vivid intraoperative venous visualization and blood flow analyses.MethodsWe retrospectively reviewed patients who underwent brain tumour resection with the application of indocyanine green videoangiography (ICG-VA) integrated with FLOW 800 from February 2019 to December 2020 and present our clinical cases to demonstrate the process of venous preservation. Galen, sylvian and superior cerebral veins were included in these cases.ResultsClear documentation of the veins from different venous groups was obtained via ICG-VA integrated with FLOW 800, which semiquantitatively analysed the flow dynamics. ICG-VA integrated with FLOW 800 enabled us to achieve brain tumour resection without venous injury or obstruction of venous flux.ConclusionsICG-VA integrated with FLOW 800 is an available method for venous preservation, although further comparisons between ICG-VA integrated with FLOW 800 and other techniques of intraoperative blood flow monitoring is needed.

Prenatal diagnosis of Galen vein aneurysm: when to deliver?

Objective: Prenatal diagnosis of Galen vein aneurysm using color Doppler has become relatively easy. Management and timing of delivery is however challenging because of cardiac function deterioration. Ultrasound follow-up is essential to detect signs of fetal cardiac failure which must be weighed against risks of prematurity. Postnatal deterioration of the vital signs can follow a short period of improvement after birth. This report illustrates the many pitfalls that could affect the final outcome, raising the issue of the proper timing for delivery. Case(s): A 23-year-old G1P0 spontaneous pregnancy was referred at 28 WA for a Galen Vein aneurysm. The ultrasound finding included a 35 by 14 mm vascular structure with a turbulent flow, occupying the central part of the head. After 48 hours in-hospital surveillance through non-stress tests twice daily, she had a cesarean section due to a persistent non-reactive fetal heart rate, with absent variability. Unfortunately, despite a stable state for the first ten days, the baby’s cardiac function deteriorated abruptly on day 11, and the baby died of heart failure despite medical management. Conclusion: The timing of delivery in cases with Galen vein aneurysm is challenging mainly in the case of premature babies, as the prognosis is globally bad. Postnatal deterioration of the vital signs can follow a short period of improvement after delivery.

Церебральний венозний тромбоз (клінічний випадок)

Тромбоз мозкових вен і венозний тромбоз мозкових синусів зустрічається рідко (до 1 % від усіх випадків інфарктів мозку). За даними ISCVT (International Study on Cerebral Vein and Dural Sinus Thrombosis, 2004), захворюваність щорічно становить 3–4 випадки на 1 млн у дорослих. Летальність при даному захворюванні становить від 5 до 30 %. Міжнародне дослідження тромбозу мозкових вен та венозних синусів (ISCVT) визначало частоту оклюзій за локалізацією так: поперечний синус — 86 %, верхній сагітальний синус — 62 %, прямий синус — 18 %, кортикальні вени — 17 %, внутрішні яремні вени — 12 %, вена Галена і внутрішні мозкові вени — 11 %. Основними факторами ризику розвитку тромбозу мозкових вен і венозного тромбозу мозкових синусів у популяції є інфекційні запальні процеси (отити, мастоїдити, синусити, септичні стани) і неінфекційні причини: черепно-мозкова травма, пухлини, хірургічні втручання в ділянці голови та шиї, а також імплантація кардіостимулятора чи постановка центрального венозного катетера. Захворювання, що сприяють даній патології: порушення гемодинаміки (застійна серцева недостатність, зневоднення організму), захворювання крові (поліцитемія, серпоподібноклітинна анемія, тромбоцитопенія) і коагулопатії (синдром дисемінованого внутрішньосудинного згортання крові, дефіцит антитромбіну, протеїну С і S), а також тромбофілітичні стани, пов’язані з вагітністю, родами та прийомом пероральних контрацептивів, антифосфоліпідний синдром, системні васкуліти. При цьому в 15 % випадків причина розвитку синус-тромбозу залишається невстановленою. Венозний тромбоз мозкових синусів характеризується дуже різноманітним клінічним перебігом, складною діагностикою, різноманітною етіологією і прогнозом. Одним з ускладнень тромбозу синусів є інсульт, що спостерігається приблизно в 30 % хворих та часто призводить до смерті хворого. У статті подано опис клінічного випадку церебрального венозного тромбозу, що ускладнився несумісним із життям двопівкульним субарахноїдально-паренхіматозним крововиливом.

Abnormal development of cerebral arteries and veins in offspring of experimentally preeclamptic rats: Potential role in perinatal stroke

Preeclampsia, a hypertensive disorder of pregnancy, complicates up to 10 % of all pregnancies and increases the risk for perinatal stroke in offspring. The mechanism of this increase is unknown, but may involve vascular dysfunction. The goal of this study was to evaluate the effect of experimental preeclampsia (ePE) on cerebrovascular function in offspring to eludciate a possible mechanism for this association. Dams were fed a high cholesterol diet beginning on day 7 of gestation to induce experimental preeclampsia. Middle cerebral arteries (MCA) and the Vein of Galen (VoG) were isolated from pups from ePE dams and compared to pups from normal pregnant (NP) dams at postnatal days 16, 23, and 30 and studied pressurized in an arteriograph chamber. Markers of inflammation and oxidative stress were measured in serum. Our results suggest altered structure and function in both MCA and VoG of ePE pups. We also found evidence of systemic inflammation and oxidative stress in ePE pups. These findings provide a potential link between preeclampsia and the occurrence or severity of perinatal stroke.

CT angiographic study of the cerebral deep veins around the vein of Galen.

Research on the anatomy of cerebral deep veins (CDVs) around the vein of Galen (VG) is very important and has fundamental clinical significance. Large-scale anatomical studies of CDVs using computed tomography angiography (CTA) are rarely reported. A retrospective study of the CDVs around the VG was conducted in Chinese patients of Han nationality. One hundred cases were included in the final analysis. The patients were aged from 17 to 78 years (mean: 42.3 years). Also, 46% of the patients were female. The diameter of the internal cerebral vein (ICV) at its beginning and termination points ranged from 0.4 to 2.8 mm (1.49 ± 0.39 mm) and 0.4 to 3.5 mm (2.05 ± 0.47 mm), respectively. There was statistical significance regarding the diameter of the ICV at its beginning and termination points (P <0.01). The ICV length ranged from 28.5 to 47.9 mm (36.86 ± 3.74 mm). The length of the straight sinus (SS) ranged from 30.2 to 57.8 mm (43.6 ± 6.37 mm). The length of the VG ranged from 1.5 to 41.8 mm (9.30 ± 4.76 mm). The angle at the VG and SS transition area ranged from 25.4 to 110.6° (77.2 ± 18.0°). This study was a meaningful attempt to conduct anatomical research of CDVs using CTA. Preoperative familiarity with the normal venous structure and its variation around the VG would be helpful for endovascular treatment.

Reinvestigation of the origins of pineal meningiomas based on its related veins and arachnoid membranes

BackgroundA series of patients harboring pineal region meningiomas were respectively analyzed to explore the origin of these tumors and the true meaning of the term “velum interpositum (VI) meningiomas”.Methods21 patients with pineal meningiomas underwent operation in Nanfang Hospital of Southern Medical University from January 2005 to December 2016 were retrospectively included to analyze the clinical features, imaging findings and surgical video data of these patients. According to the method of literature, the data of this group were also divided into falcotentorial (FT) meningiomas and VI meningiomas, and the differences between the two types of tumors were compared.ResultsAmong the 21 cases of tumor, there were 12 cases of FT meningiomas, including 4 cases originating from cerebral falx, 4 cases from tentorium of cerebellum and 4 cases from straight sinus; there were 9 cases of VI meningiomas, 7 of which originated from the arachnoid sleeve of the Galen vein, 1 from the posterior part of the internal cerebral vein and 1 from the posterior surface of the pineal gland. Postoperative pathological examination showed meningiomas in all the 21 patients, including 16 cases of total resection and 5 cases of subtotal resection. Postoperatively limitation of binocular vertical motion was found in 3 cases, homotropic hemianopia in 7 cases, hemiplegia in 1 case and death in 1 case.ConclusionsThis study suggests that pineal meningiomas are more suitable to be described by FT meningioma and meningiomas of the arachnoid of the pineal region by analyzing the origin of tumors. The term “VI meningiomas” can only reflect a part of meningiomas of the arachnoid of the pineal region. Before the removal of pineal meningiomas, more attention should be paid to the effects of the two types of tumors on the Galen vein and the straight sinus, and the establishment of venous collateral circulation.

DIAGNOSTIC OPPORTUNITIES OF PARA INFRARED SPECTROSCOPY IN FULL-TERM NEWBORNS DURING THERAPEUTIC HYPOTHERMIA IN THE POST ASPHYXIAL PERIOD

Introduction. Despite the achievements of neonatology, severe birth asphyxia in full-term infants is still associated with high mortality, long-term neurological morbidity and disability. In the algorithm of managing children with hypoxic-ischemic encephalopathy, it is important to use additional testing methods for early assessment of the severity of brain tissue damage. Assessment of cerebral oxygenation by near-infrared range (near-infrared spectroscopy, NIRS) has strong correlation with MRI brain perfusion in full-term newborns with hypoxic-ischemic encephalopathy. However, recommendations for the use of NIRS monitoring data in neonates with asphyxia and hypoxic-ischemic encephalopathy may differ in routine clinical practice.The objective of the study was to determine the relationship between brain perfusion measurements using NIRS and post asphyxial period characteristics (clinical symptoms, neurosonography, and cerebral artery Doppler ultrasound) in full-term newborns during therapeutic hypothermia.Materials and methods. Full-term infants with severe birth asphyxia who underwent therapeutic hypothermia were examined: 33 infants who had no signs of destructive brain damage, and 15 with destructive hypoxic-ischemic lesions. The results of the NIRS recordings in the post asphyxial period were compared with those of the clinical manifestations and the results of neurosonography and cerebral artery dopplerography.Results. Significant differences (p &lt; 0.05) between observation groups were found regarding the registration of left frontal lobe NIRS: mean rSO2 (p=0.012; 84.01±2.64 % in children with destructive brain lesions) against 76.56±1.71 % in children without destructive lesions); the 25th percentile level of rSO2 (p=0.024, 80.47±2.89 % vs. 72.36±1.75 %, respectively), the 75th percentile of rSO2 (p=0.008, 88.20±2.66 vs. 80.88±1.78). There were no significant differences in the registration of NIRS indicators on the right side. Significant correlation relationships of average strength were recorded between the Galen vein blood flow rate (measurement on the 4th day of life) and the rSO2 average rates on the left (R=0.58), and on the right (R=0.52)Conclusions. Significant differences in the NIRS record scores of children groups with destructive hypoxic-ischemic changes in brain tissue and without destructive changes were observed (Max average rSO2 value on the left during destructive lesions formation). Max average rSO2 values were observed in both left- and right-sided monitoring and were associated with a higher rate of cerebral venous blood flow beyond hypothermia period.
