The carotid artery is a major blood vessel that transports blood from the heart to the head, face, and neck, and it is also one of the primary blood - supplying vessels for the brain. The formation of plaques in the cervical blood vessels significantly elevates the risk of myocardial infarction, stroke, and peripheral vascular diseases such as lower extremity arterioscle...

Carotid Endarterectomy (CEA) is a well-established and widely performed surgical procedure used to treat patients at high risk of stroke due to carotid artery atherosclerotic stenosis. By directly removing atherosclerotic plaque from the carotid artery, the procedure restores cerebral blood flow and is considered one of the most effective interventions for preventing isc...

Interrupted aortic arch (IAA) is a rare but life-threatening congenital heart defect characterized by a complete discontinuity of the aorta at the level of the aortic arch. This interruption prevents normal blood flow from the left ventricle to the lower part of the body. Under normal conditions, the heart consists of four chambers: two atria and two ventricles. The left...

Pulmonary valve atresia is a congenital heart disease characterized by fusion of the pulmonary valve leaflets into an imperforate membranous structure, resulting in obstruction of blood flow between the right ventricle and the pulmonary artery. The condition is classified into two main types: pulmonary atresia with intact ventricular septum and pulmonary atresia with ven...

1. What is the Ductus Arteriosus? The ductus arteriosus is a normal fetal blood vessel that connects the pulmonary artery to the aorta. This vessel allows oxygen-poor blood to bypass the non-functioning fetal lungs and flow directly into the aorta, helping to distribute blood throughout the fetus via the placenta. Normally, one end of the ductus originates from the left...

Clinical presentations of CTO patients are diverse. Most CTO patients undergoing PCI have typical angina symptoms, while 11%–15% are asymptomatic. 42%–68% of CTO patients confirmed by coronary angiography have a history of myocardial infarction. CTO patients can be broadly divided into two categories based on their clinical presentation: one group presents with stable an...

The most common form of embolism is a thrombus originating from the heart (a common cause is atrial fibrillation leading to atrial thrombosis), which breaks off and blocks the arteries of the lower limbs. This causes acute ischemia in the lower limbs, resulting in symptoms. Acute arterial embolism has a rapid onset and severe symptoms. If extensive embolism occurs and su...

For old or subacute strokes, thrombectomy is neither necessary nor advisable. After an embolus blocks a blood vessel for a period, permanent infarction occurs, and the brain tissue has already lost its function. Opening the vessel will not save this brain tissue (it's useless); in fact, it may cause reperfusion injury or cerebral hemorrhage (harmful). For small vessel (n...

Vascular interventional techniques are procedures performed via blood vessels under the guidance of medical imaging equipment, using instruments such as puncture needles, guidewires, and catheters for diagnosis and treatment.

First, smoking is the most important factor. According to relevant research data, smokers are 2-8 times more likely to develop chronic bronchitis than non-smokers. This is because nicotine, tar, and hydrogen cyanide in cigarette smoke are substances that strongly damage bronchial wall cells. They can damage the ciliated cells of the bronchial wall, reducing the lung's se...

Colorectal cancer is one of the most common cancers worldwide, but with early detection, it is also one of the most preventable and treatable. One of the most effective tools for screening and diagnosis is colonoscopy—a widely used procedure that allows doctors to examine the inner lining of the colon and rectum. What is a Colonoscopy? A colonoscopy is a medical procedur...

The heart is a powerful organ that pumps blood throughout the body, delivering oxygen and nutrients to tissues and removing waste products. It has four chambers — two upper chambers called the atria and two lower chambers called the ventricles. Normally, the left and right atria are separated by a wall called the atrial septum. An Atrial Septal Defect (ASD) is a congenit...

Pulmonary Arterial Hypertension (PAH) is a rare but serious condition that affects the blood vessels in the lungs and the right side of the heart. It is a type of high blood pressure, but unlike regular high blood pressure (which affects the whole body), PAH specifically occurs in the pulmonary arteries — the vessels that carry blood from the heart to the lungs. What Hap...

Appendicitis is one of the most common surgical emergencies, and appendectomy remains the primary treatment. With advances in surgical techniques, laparoscopic appendectomy has become the preferred approach in many hospitals. However, open surgery is still necessary in complex or advanced cases.

(1) Structure of the Gastric Mucosa The gastric mucosa is the innermost layer of the stomach wall and consists of the epithelium, lamina propria, and muscularis mucosae. The epithelium is a single layer of columnar epithelial cells tightly arranged to effectively prevent autodigestion by gastric acid and pepsin. On the surface of the gastric mucosa lies a mucus–bicarbona...

Your heart has four valves that act like one-way doors, guiding blood in the correct direction. One of these valves, the aortic valve, plays a particularly important role. It opens every time your heart beats, allowing oxygen-rich blood to flow from the left ventricle into the aorta and out to the rest of your body. Aortic valve stenosis (AS) occurs when this valve becom...
