Summary: Cavernous sinus dural arteriovenous fistula (CSDAVF) is a rare intracranial vascular malformation that can be easily missed or misdiagnosed. Interventional embolization therapy is an effective treatment for CSDAVF, with digital subtraction angiography (DSA) being the gold standard for diagnosis. A 42-year-old female patient with CSDAVF experienced improvement in symptoms after receiving interventional treatment.

Summary: This study aimed to investigate sinovenous outflow restriction (SOR) in lateral sinus dural arteriovenous fistulas (LSDAVFs) after Gamma Knife radiosurgery (GKRS) and its association with complete obliteration. The study found that after GKRS, the ipsilateral LS became more restrictive and patients with SOR had a lower obliteration rate. Therefore, follow-up imaging for SOR may help predict outcomes of these patients.

Summary: From 9 studies meeting the inclusion criteria, CTA has reasonable specificity but low sensitivity in diagnosing any BCVI compared to DSA. Increasing the channel to 64 slices did not improve sensitivity. Using only DSA to confirm CTA-positive cases, especially in patients with low-grade injuries, poses a risk of underdiagnosis of BCVI.

Summary: This study evaluated the potential cost reduction of forgoing postoperative DSA after microsurgical occlusion of DI-AVFs. The results showed that ICG-VA can effectively demonstrate the microsurgical cure of DI-AVFs, and confirming obliteration on ICG-VA and eliminating postoperative DSA can save substantial costs and spare patients from the risk and inconvenience of a potentially unnecessary invasive procedure.

Summary: Intracranial mass lesions have diverse etiologies, including tumors, hemorrhagic diseases, and vascular malformations. Misdiagnosis of these lesions is common due to the lack of primary disease manifestations. Comprehensive preoperative examination is crucial for accurate diagnosis and treatment, especially in cases like craniocervical junction arteriovenous fistulas (CCJAVFs), which can be initially misdiagnosed as brainstem tumors. Interventional treatment can be effective in curing CCJAVFs, avoiding the need for invasive craniotomy.

Summary: In this study, quantitative digital subtraction angiography (QDSA) was used to explore the hemorrhagic quantitative hemodynamic indicators of brain arteriovenous malformation (AVM) nidus. The results showed that a higher stasis index and slower transnidal relative velocity (TRV) were significantly correlated with AVM rupture and could be used as effective indicators to predict future hemorrhage risk.

Summary: The aim of this study was to determine the yield of routine whole-body CT following ECMO initiation and its association with prognosis. In a retrospective study of 198 patients with acute respiratory failure admitted for ECMO support, clinically significant findings were present in 74% of patients, findings requiring further workup in 41%, and benign findings in 90%. Clinically significant neurological findings were associated with an elevated risk of death at 7 days, and an increasing number of clinically significant findings were associated with greater odds of mortality at both 7 and 30 days. These findings support the use of more routine CT at the point of treatment escalation and call for further prospective studies.

Summary: Chronic thromboembolic pulmonary hypertension (CTEPH) is a condition that occurs in some patients with prior acute pulmonary embolism, characterized by shortness of breath, persistently elevated pulmonary pressures, and right heart failure. Surgical pulmonary endarterectomy (PEA) is effective for patients with proximal disease distribution, while balloon pulmonary angioplasty (BPA) and medical therapy are options for those with inoperable disease. Current evaluation of pulmonary hemodynamics does not accurately reflect patient symptoms, and further research is needed on how to manage symptomatic patients without pulmonary hypertension.

Summary: This study examined the nasal and plasma antibody responses in COVID-19 hospitalized patients one year after discharge and vaccination. The findings showed sustained elevated antibody responses in both nasal and plasma samples for at least 12 months, but the nasal antibody response was minimally influenced by vaccination. These findings highlight the importance of developing vaccines that enhance nasal immunity.

Summary: Data science systems are widely used in research and developed by people from various backgrounds, but the reproducibility of such systems is facing a crisis. Perverse incentives and a lack of software engineering skills contribute to this crisis. By analyzing the difficulties in software engineering and building complex systems, we propose applying software engineering methods to make data science systems more suitable for their purpose. We advocate for incremental growth and the use of two types of feedback loops in development - one for testing code correctness and another for evaluating code efficacy.

Summary: Pulmonary endarterectomy (PEA) may not fully resolve vascular obstructions in more distal chronic thromboembolic pulmonary hypertension (CTEPH). Balloon pulmonary angioplasty (BPA) can be used to treat these residual lesions. This study compared the outcomes of BPA treatment in patients post-PEA (PP) and inoperable CTEPH (IC) patients. The results showed that IC patients derived greater benefit from BPA in terms of hemodynamic improvement. There was a negative correlation between pre-BPA pulmonary vascular resistance (PVR) and total thrombus tail length (TTTL), which persisted post-BPA in PP patients.
