Time and Influencing Factors to Chronic Subdural Hematoma Resolution After Middle Meningeal Artery Embolization.

Objective: We sought to describe the resolution time of chronic subdural hematoma (CSDH) after middle meningeal artery embolization (MMAE) and potential variables that may affect hematoma resolution.

Methods: A retrospective analysis was performed on CSDH patients between December 2018 and December 2021. Patient characteristics, radiologic manifestations, and data of hematoma resolution were recorded.

Comparison of Micro-Clamping Stent-Retriever Thrombectomy with Conventional Stent-Retriever Thrombectomy in Intracranial Large Vessel Embolism.

Objective: To evaluate the effectiveness of micro-clamping stent-retriever thrombectomy (MSRT) in patients with acute ischemic stroke with intracranial large vessel embolism (ILVE), and compare it with that of conventional stent-retriever thrombectomy (CSRT).

Methods: We retrospectively evaluated 108 patients with ILVA treated by MSRT (n = 52) or CSRT (n = 56) from the 2 participating institutions between January 2016 and November 2017. The rates of successful (Modified Thrombolysis in Cerebral Infarction [mTICI] grade 2b or 3) and complete reperfusion (mTICI grade 3), time from guide catheter placement to reperfusion, rates of first-pass success, and the number of passes for reperfusion were compared between the MSRT and CSRT groups.

Thrombectomy Using "Clamping Embolus with Semi-Retrieval" Technique in Acute Ischemic Stroke.

Background: Embolization of thrombus fragments in new or downstream vascular territories is a potential adverse event in neurothrombectomy, requiring additional repeated thrombectomy attempts. This study aims to describe technical results of the thrombectomy with clamping embolus technique (TCET) method in acute ischemic stroke. This study also aims to evaluate the efficiency of mechanical thrombectomy by TCET, and to compare it with conventional stent retriever thrombectomy (CSRT).

Sufficient collateral blood supply from accessory middle cerebral artery in a patient with acute ischemic stroke.

We reported a case of acute embolic occlusion of the middle cerebral artery with a patent accessory middle cerebral artery. Because of the presence of sufficient collateral blood supply from the accessory middle cerebral artery, the patient only underwent transient ischemic attack and did not need endovascular treatment. There was mild infarction in the basal ganglia and temporal lobe, NIHSS score of the patient at discharge seven days after stroke onset was 0, and modified Rankin scale score at 90 days was 0.

Massive hemoptysis from pulmonary ligament artery supplying abnormal basal segments of the lower lobe.

Background: Non-bronchial systemic arteries can be a significant source of massive hemoptysis in patients with marked pleural involvement. However, in some cases without pleural involvement, the pulmonary ligament artery (PLA) can also enter the abnormal lung parenchyma and be responsible for hemoptysis.

Purpose: To discuss the factors influencing the development of a blood supply from the PLA in patients with hemoptysis.
