Septic cavernous sinus thrombosis (SCST) is a rare infectious thrombophlebitic disease. The infection often arises from the tissues surrounding the cavernous sinus as well as the cavernous sinus drainage. Early symptoms of SCST include fever, headache, proptosis, ptosis, bulbar conjunctival edema, and limited eye movement. The complications include venous sinus thrombosis, intracerebral abscess, and subdural empyema. Aneurysmal subarachnoid hemorrhage combined with acute cerebral infarction has not been reported. ⋯ We report a case of SCST mainly presenting as acute cerebral infarction and aneurysmal subarachnoid hemorrhage, with an acute onset and ultimately a poor prognosis. This complication is extremely rare and have not yet reported according existing literatures but can be life-threatening if not recognized and treated promptly. Early antibiotic administration and early sinus drainage may alter the patient's prognosis. By describing this unusual the case we hope to raise awareness of the need of early illness detection and treatment in order to avoid catastrophic consequences. It also exemplifies the mechanism of acute inflammatory disorders and aneurysm development.

The associations of neutrophil to lymphocyte ratio (NLR) and red cell distribution width (RDW) with the prognosis of aneurysmal subarachnoid hemorrhage (aSAH) patients were confirmed in a few studies. But NLR and RDW levels in most of these studies were on admission. Here we carried 1 retrospective study including 150 patients with aSAH who underwent surgeries in the First Affiliated Hospital of Yangtze University from January 2020 to February 2023 to explore the associations on the preoperative day, the first (1st), third (3rd), and seventh (7th) postoperative days. ⋯ Higher RDW on the 3rd postoperative day and NLR on the 7th postoperative day were possibly associated with poor prognosis of aSAH patients. We should pay attention to the RDW and NLR levels during different hospitalization periods, especially in the short postoperative period. Moreover, the cutoff values for predicting prognosis need to be validated in larger-sample studies.

Observational Study
Myocardial dysfunction assessed by speckle-tracking in good-grade subarachnoid hemorrhage patients (WFNS 1-2): a prospective observational study.
Cardiac complications due to non-traumatic subarachnoid hemorrhage (SAH) are usually described using classical echocardiographic evaluation. Strain imaging appears to have better sensitivity than standard echocardiographic markers for the diagnosis of left ventricular dysfunction. The aim of this study was to determine the prevalence of cardiac dysfunction defined as a Global Longitudinal Strain (GLS) ≥ - 20% in patients with good-grade SAH (WFNS 1 or 2). ⋯ Strain imaging showed a higher prevalence (60.6%) of left ventricular dysfunction during the acute phase of good-grade SAH (WFNS 1 or 2) than previously described.

Spinal intramedullary arteriovenous malformations (AVMs) can present with spinal hemorrhage. However, some of them occasionally can be the cause of angiographically negative intracranial subarachnoid hemorrhage, thus requiring a more comprehensive diagnostic approach to detect the possible source of bleeding. Nidal or arterial feeder aneurysms are widely considered high-risk rupture portions of the spinal AVM and recognized as a major cause of bleeding. ⋯ The case of a 25-year-old man with acute cerebral subarachnoid hemorrhage caused by intranidal aneurysm rupture of cervical glomus-type AVM is presented here. The patient was surgically treated by C3-C4 laminectomy and AVM excision by pial resection technique. Thereby, the pial resection technique helps in providing subtotal AVM nidus resection, minimizing parenchymal dissection but effectively devascularizing glomus AVMs with satisfactory long-term results.

Randomized Controlled TrialEarly stellate ganglion block for improvement of postoperative cerebral blood flow velocity after aneurysmal subarachnoid hemorrhage: results of a pilot randomized controlled trial.
Stellate ganglion block (SGB) is a commonly used sympathetic nerve block technique that may have benefits for patients with aneurysmal subarachnoid hemorrhage (aSAH) in the early stage. Cerebral vasospasm (CVS), one of the most common complications of aSAH, is accompanied by an abnormal increase in cerebral blood flow velocity (CBFV) and neurological dysfunction. In this pilot study the authors sought to determine the feasibility of early SGB for CVS in aSAH patients by observing the incidence of symptomatic CVS. ⋯ This pilot study demonstrated for the first time, to the authors' knowledge, that early SGB is feasible and has the potential to reduce the risk of CVS and improve the prognosis of aSAH. This method may be a new treatment for patients with aSAH that may have more advantages than traditional therapeutic drugs and is worth further study.
