[Posterior scala duralis arterio-venosus malformation ]


[The authors describe a case of dural arteriovenous malformation localized to the posterior scala. In doing so, they discuss the aetiology, clinical and radiographic features of the atheromaly. An interesting feature of their case is that, in addition to the shunt discovered on angiography, a similar abnormality was found in the pons at autopsy. ]

[Neuroendocrine study of the dopaminergic system in acute schizophrenia]

ARATÓ Mihály, ALFÖLDI Antal, MÓD László, PAPP Zsuzsa, BAGDY György, BROWN M. Gregory

[The authors investigated putative indicators of central dopaminergic mechanisms - serum prolactin, growth hormone and dopamine B-hydroxylase and their changes induced by 0.25 mg sc, apomorphine - in 12 young male, never treated with medication, acute schizophrenics. The schizophrenics showed significantly lower prolactin levels than healthy control subjects. No consistent change in DBH activity was observed in the schizophrenic group following apomorphine administration, compared with the healthy group, where a small but significant increase in DBH activity was observed. Five schizophrenic patients showed the 5 highest growth hormone responses to apomorphine, but the difference between the two groups was not significant. ]

The applications of transcranial Doppler in ischemic stroke


Background: This overview provides a summary of the applications of transcranial Doppler (TCD) in ischemic stroke. Results: A fast-track neurovascular ultrasound protocol has been developed for detecting occlusion or stenosis. The technique is more reliable in the carotid area than in the posterior circulation. By monitoring the pulsatility index the in­crea­sed intracranial pressure can be diagnosed. TIBI score was developed for grading residual flow. TCD has been shown to accurately predict complete or any recanalization. Regarding recanalization, TCD has a sensitivity of 92%, a specificity of 88%, a positive predictive value of 96%, a negative predictive value of 78% and an overall accuracy of 91%, respectively. Sonothrombolysis seemed to be a promising application but randomized controlled trials have shown that it does not improve clinical outcome. TCD examination can detect microembolic signals (MES) which are associated with an increased risk of stroke. Micro­em­boli were detected in symptomatic and asymptomatic carotid artery stenosis and during carotid endarterectomy. The number of microemboli can be decreased by antithrombotic therapy. Contrast en­chan­ced examination and Valsalva maneuver with continuous TCD monitoring can accurately screen for right-to-left shunt.

[A case of destructive cervical spondylarthropathy related to chronic dialysis]

[A case of a 61-year-old male patient suffered chronic renal failure and dialysed for 23 years with destructive cervical spondylarthropathy is presented. The patient presented with sudden onset of cervical pain radiating into his shoulders without neurological deficits. CT and MRI of the cervical and thoracic spine revealed severe destructive changes and compressive fractures of C6 and C7 vertebrae which caused the narrowing of the nerve root canals at these levels. A 360-degree fixation was performed to treat the unstable fracture and the patient’s pain (C6 and C7 corpectomy, autolog bone graft replacement of the two vertebral bodies, anterior plate fixation and posterior instrumentation with screws and rods). Postoperatively the patient had no significant pain, no neurological deficit and he was able to manage independent life himself. During the immediate follow-up CT of the neck showed the satisfactory position of the bone graft and the metal implantations. The 6 months follow-up CT revealed the anterior migration of the two screws from the Th1 vertebral body and 2 mm ventral elevation of the caudal end of the plate from the anterior surface of the Th1 vertebral body. The 1-year follow-up could not be performed because the patient died due to cardio-pulmonary insufficiency. This is the second Hungarian report of a chronic dialysis related severe spondylarthropathy which may cause pathologic fractures of the vertebral bodies. The typical radiological and histological findings are discussed. This disease affect patients’ quality of life and the conservative treatment alone seems to be ineffective in most cases. Based on the literature and personal experiences, the authors suggest 360-degree fixation of the spine to provide sufficient stability for the vertebrae of ”bad bone quality”, and early mobilisation of the patient can be achieved.]

[Treatment options for enormous carotid thrombus as a complication of SARS-CoV-2 infection]

KONCZ Júlia, OROSZ Viktor, SULYOK Zoltán, ANDRÁS Emőke, KÁDÁR Balázs, OLÁH Csaba

[In SARS-CoV-2 positive patients with corresponding neurological symptoms the presence of carotid bifurcation macrothrombus should always be considered. Hypercoagulopathy caused by viral endotheliitis, systemic inflammation and cytokine storm play an important role in its development. Here we present two patients treated with different treatment strategies because of carotid bifurcation macrothrombus as a complication of SARS-CoV-2 infection. In both cases, the soft macrothrombus was eliminated and the patients’ neurological condition were improved. Intravenous thrombolysis, acute carotid stenting with embolic filter protection device and mechanical thrombectomy with aspiration are effective treatments.]

Simultaneous subdural, subarachnoideal and intracerebral haemorrhage after rupture of a peripheral middle cerebral artery aneurysm


The cause of intracerebral, subarachnoid and subdural haemorrhage is different, and the simultaneous appearance in the same case is extremely rare. We describe the case of a patient with a ruptured aneurysm on the distal segment of the middle cerebral artery, with a concomitant subdural and intracerebral haemorrhage, and a subsequent secondary brainstem (Duret) haemorrhage. The 59-year-old woman had hypertension and diabetes in her medical history. She experienced anomic aphasia and left-sided headache starting one day before admission. She had no trauma. A few minutes after admission she suddenly became comatose, her breathing became superficial. Non-contrast CT revealed left sided fronto-parietal subdural and subarachnoid and intracerebral haemorrhage, and bleeding was also observed in the right pontine region. The patient had leucocytosis and hyperglycemia but normal hemostasis. After the subdural haemorrhage had been evacuated, the patient was transferred to intensive care unit. Sepsis developed. Echocardiography did not detect endocarditis. Neurological status, vigilance gradually improved. The rehabilitation process was interrupted by epileptic status. Control CT and CT angiography proved an aneurysm in the peripheral part of the left middle cerebral artery, which was later clipped. Histolo­gical examination excluded mycotic etiology of the aneu­rysm and “normal aneurysm wall” was described. The brain stem haemorrhage – Duret bleeding – was presumably caused by a sudden increase in intracranial pressure due to the supratentorial space occupying process and consequential trans-tentorial herniation. This case is a rarity, as the patient not only survived, but lives an active life with some residual symptoms.

In this study, we wanted to investigate the effect of antiplatelet and anticoagulant use on the success of mechanical thrombectomy in acute ischemic stroke cases. 174 patients who were brought to the Stroke Center of Gaziantep University Şahinbey Research and Practice Hospital between January 2018 and February 2019 due to acute ischemic stroke and who underwent mechanical thrombectomy were retrospectively analyzed. The demographic characteristics, antiplatelet/anticoagulant use before the stroke and mTICI (modified-Throm­bolysis-In-Cerebral-Infarction) scores used for reperfusion in mechanical thrombectomy were evaluated. The findings were analyzed statistically (p<0.05). The mean age was 63.3 ± 13.5 in 174 patients who underwent mechanical thrombectomy. 23/174 (13.2%) patients were using anticoagulant therapy (warfarin-OAC or new generation oral anticoagulant-NOAC) and 28/174 (16.1%) were using antiplatelet therapy. A history of atrial fibrillation (AF) was significantly higher in patients receiving anticoagulant therapy before acute ischemic stroke (p=0.001). Patients with a history of hyper tension (HT), diabetes mellitus (DM) and coronary artery disease (CAD) before acute ischemic stroke were receiving antiplatelet therapy in higher rates (respectively; p=0.003, p=0.037, p=0.005). Successful recanalization (mTICI ≥ 2b) was higher in patients with a history of anticoagulant use and who underwent mechanical thrombectomy (p=0.025). Our study showed that the use of anti­platelet or anticoagulants before mechanical thrombec­tomy may have an indirect positive effect on the success of the procedure.
