Dual left anterior descending artery (LAD) is a rare variation in the coronary artery anatomy having 4 different subtypes. We report a rare scenario of type IV dual LAD, with short LAD critical stenosis, compensated by a long LAD perfusing the same territory, which was missed on initial angiographic evaluation. Myocardial perfusion scan (MPS) of this patient showed preserved perfusion. A review of angiogram revealed this anomaly, indicating that a meticulous correlation of anatomic and functional modalities is necessary as it could change further management of patient.

Cancer and antiphospholipid syndrome (APS) independently increase thrombotic risk, and their coexistence can create a particularly hazardous prothrombotic state. This case report aims to highlight the complex challenges in managing concurrent thrombotic and hemorrhagic events in patients with a history of cancer and APS. The combination of these conditions presents a rare and difficult clinical scenario, requiring careful consideration in anticoagulation management.

Background: While acute occlusion of the subclavian artery (SCA) proximal to the vertebral artery (VA) origin is an uncommon but recognized cause of embolic stroke, an occlusion distal to the VA is rare and can be easily overlooked.
Case Description: We describe the clinical presentation and evaluation of a previously healthy 56-year-old woman who experienced four life-threatening posterior circulation strokes within 1 month, three of which led to basilar artery (BA) occlusions requiring thrombectomies. Workup revealed an occlusion of the right SCA located less than 1 cm distal to the VA origin.

In the Imbalanced Multivariate Time Series Classification (ImMTSC) task, minority-class instances typically correspond to critical events, such as system faults in power grids or abnormal health occurrences in medical monitoring. Despite being rare and random, these events are highly significant. The dynamic spatial-temporal relationships between minority-class instances and other instances make them more prone to interference from neighboring instances during classification.

Kissing aneurysms, a rare and intriguing cerebrovascular anomaly, challenge even the most advanced neurosurgical techniques. These lesions, characterized by two intimately apposed aneurysms with shared arterial walls, often masquerade as single, irregular aneurysms. This report documents a case of ruptured kissing aneurysms in the M1 segment of the right middle cerebral artery (MCA), complicated by ischemic stroke and pulmonary thromboembolism (PTE)-a convergence of severe complications rarely encountered.

: Granulomatosis with polyangiitis (GPA) represents a rare autoimmune disease with granulomatous inflammation, tissue necrosis, and systemic vasculitis of the small and medium blood vessels. Although the clinical elements vary, aortic involvement is exceptional and it represents a challenge that requires a rapid intervention with the potential of displaying a fulminant evolution. : We report a 64-year-old male with an 18-year history of GPA who presented atypical low back pain.
