Bilateral chronic subdural hematoma (bCSDH) represents a common neurosurgical entity frequently associated with elevated retreatment rates. However, the underlying mechanisms driving its high recurrence remain incompletely understood. Emerging evidence implicates the middle meningeal artery (MMA) in the pathogenesis and progression of chronic subdural hematomas. The authors present a case of bCSDH managed with combined bilateral MMA embolization and burr hole evacuation in a 79-year-old male. The patient had sustained a closed head injury 3.5 months prior, initially managed with bilateral burr hole drainage. Recurrent bCSDH was diagnosed 1 month before presentation. After bilateral MMA embolization integrated with burr hole drainage, serial head CT demonstrated progressive resolution of the bCSDH. The patient achieved uneventful recovery with no recurrence observed during follow-up. This case highlights the efficacy of combined bilateral MMA embolization and surgical evacuation for bCSDH, suggesting its potential to mitigate recurrence risk.

Veins of Head and Neck01:19

Veins of Head and Neck

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Esophageal Varices-II: Clinical Features and Management

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
