Bronchial artery perfusion scintigraphy to assess bronchial artery blood flow after lung transplantation. (1/114)

The bronchial arterial system is inevitably interrupted in transplanted lungs when removing the organs from the donor, but it can be reestablished by direct bronchial artery revascularization (BAR) during implantation. The purpose of this study was to visualize and quantify the distribution of bronchial artery perfusion after en bloc double lung transplantation with BAR, by injecting radiolabeled macroaggregated albumin directly into the bronchial artery system. METHODS: BAR was performed using the internal mammary artery as conduit. Patients were imaged 1 mo (n = 13) or 2 y (n = 9) after en bloc double lung transplantation with BAR. Immediately after bronchial arteriography, 100 MBq macroaggregated albumin (45,000 particles) were injected through the arteriographic catheter. Gamma camera studies were then acquired in the anterior position. At the end of imaging, with the patient remaining in exactly the same position, 81mKr-ventilation scintigraphy or conventional intravenous pulmonary perfusion scintigraphy or both were performed. Images were evaluated by visual analysis, and a semiquantitative assessment of the bronchial arterial supply to the peripheral parts of the lungs was obtained with conventional pulmonary scintigraphy. RESULTS: The bronchial artery scintigraphic images showed that the major part of the bronchial arterial flow supplied central thoracic structures, but bronchial artery perfusion could also be demonstrated in the peripheral parts of the lungs when compared with conventional pulmonary scintigraphy. There were no differences between scintigrams obtained from patients studied 1 mo and 2 y post-transplantation. CONCLUSION: Total distribution of bronchial artery supply to the human lung has been visualized in lung transplant patients. This study demonstrates that this nutritive flow reaches even the most peripheral parts of the lungs and is present 1 mo as well as 2 y after lung transplantation. The results suggest that bronchial artery revascularization may be of significance for the long-term status of the lung transplant.  (+info)

Audit of bronchial artery embolisation in a specialist respiratory centre. (2/114)

OBJECTIVE: To audit the use of bronchial arteriography and embolisation for controlling haemoptysis. DESIGN: Retrospective review of radiological and clinical data. SETTING: Brompton and National Heart Hospitals. PATIENTS: 35 patients with severe pulmonary disease in whom 58 bronchial arteriograms were obtained between 1 January 1984 and 31 December 1989 with the intention of bronchial artery embolisation for controlling haemoptysis. MAIN MEASURES: Rate of technical success and cessation of haemoptysis; detailed evaluation of patients, particularly those with major haemoptysis (> 100 ml expectorated blood); and retrospective assessment of the appropriateness of the procedure in each. RESULTS: 58 procedures were performed, nine of which were unsuitable for detailed analysis. Nine procedures were for minor haemoptysis, which subsequently recurred, and 40 for recent major haemoptysis in 26 patients with cystic fibrosis (16) aspergilloma (six), bronchiectasis (three), and an unknown diagnosis (one). The median total volume of haemoptysis in the episode before the procedure was 680 ml (range 270-2200 ml). Embolisation was technically successful in 33/40 procedures, in 17 of which, however, major haemoptysis recurred within 10 days of the procedure, leaving 16 clinically and technically successful procedures in 15 patients. Five patients (three with aspergilloma, two with cystic fibrosis) died of haemoptysis despite attempted embolisation. CONCLUSION: Success rate of bronchial artery embolisation was 40%(16/40). IMPLICATIONS: Bronchial artery embolisation is probably not justified for minor haemoptysis or when performed more than one week after a major haemoptysis. Repeat arteriograms during a single period of haemoptysis are seldom useful. With these criteria 43% fewer procedures would have been performed with no loss of clinical benefit.  (+info)

The functional anatomy of the bronchial circulation of the domestic fowl. (3/114)

The bronchial circulation was studied in 25 adult domestic fowls. The right and left bronchial arteries originated caudal to the syrinx from a bronchoesophageal artery which is a branch of the right common carotid artery. Each bronchial artery ramified on the wall of the extrapulmonary part of the corresponding primary bronchus and finally anastomosed directly with a branch of the pulmonary artery at the hilus of the lung. Thr bronchial artery did not accompany the intrapulmonary part of the primary bronchus. The branches of each bronchial artery formed an anastomosing network on the wall of the extrapulmonary part of the primary bronchus. The calibre of the bronchial artery at its anastomosis with the branch of the pulmonary artery was greater than at its origin from the bronchoesophageal artery. Intravenous injections of Lycopodium spores indicated that the blood flows from the pulmonary artery into the bronchial artery. Small bronchial veins drained the extrapulmonary part of the primary bronchus into the pulmonary vein and the oesophageal veins. The intrapulmonary part of the primary bronchus was supplied by branches of the pulmonary artery and drained by tributaries of the pulmonary vein. The blood supply to the primary bronchus could constitute a shunt capable of passing blood from the pulmonary artery into the pulmonary vein without going through the exchange tissue. The parabronchial (atrial) muscles received a blood supply directly from the exchange tissue via septal venules which formed a network underneath the muscle bundles, without actually penetrating between the muscle cells. These venules drained into atrial veins which were tributaries of the pulmonary vein. The atrial muscles probably also received oxygen by direct diffusion from the parabronchial lumen. The pleura was supplied by the oesophageal branches of the bronchoesophageal artery, and by small twigs from the internal thoracic and intercostal arteries.  (+info)

Altered contractile sensitivity of isolated bronchial artery to phenylephrine in ovalbumin-sensitized rabbits. (4/114)

We tested the hypothesis that atopy and/or allergic lung inflammation enhances alpha1-adrenoceptor-mediated contractions of the bronchial artery. Bronchial arterial resistance vessels were isolated from rabbits that had undergone either systemic ovalbumin (OVA) sensitization followed by saline aerosol challenge (OVA/saline rabbits), or OVA sensitization followed by OVA aerosol challenge (OVA/OVA rabbits), or no sensitization followed by saline aerosol challenge (control rabbits). In OVA/OVA rabbits, bronchoalveolar lavage and lung histology revealed lymphocytic and eosinophilic inflammation. Arterial rings were contracted with phenylephrine (PE). In endothelium-intact arteries isolated from OVA/saline and OVA/OVA rabbits, PE responsiveness was enhanced compared with that of arteries isolated from controls. The nitric oxide synthase (NOS) inhibitor NG-nitro-L-arginine methyl ester increased the contractile response to PE in all three experimental groups to a similar degree, suggesting that depressed NOS activity was not involved in the enhanced PE responsiveness in OVA/saline and OVA/OVA rabbits. After endothelium removal, arteries from OVA/saline and control rabbits showed similar PE responsiveness, indicating that the enhancement of PE responsiveness was endothelium dependent, possibly due to an endothelial constricting factor. In OVA/OVA rabbits, endothelium-denuded arteries showed decreased PE responsiveness compared with the other two groups; this difference was abolished by NG-nitro-L-arginine methyl ester. We conclude that systemic sensitization with OVA per se enhances PE-induced contractions of isolated bronchial arteries in rabbits by an endothelium-dependent mechanism and that allergic lung inflammation attenuates this effect by increased nonendothelial NOS activity.  (+info)

The porcine bronchial artery: surgical and angiographic anatomy. (5/114)

The pig is often used in experimental studies on the significance of bronchial artery circulation, but the anatomy of this artery is only poorly described. The purpose of this study was to improve the anatomical basis for experimental studies on the porcine bronchial artery circulation. The origin of the artery from the aorta is described in 32 pigs. Heart-lung blocks were perfused with saline and removed in 16 pigs, and the broncho-oesophageal orifice was identified and cannulated. In these 16 specimens the intrapulmonary ramification was studied by angiography, and the extrapulmonary distribution and supply area by injection of Evans Blue. The broncho-oesophageal artery originated from the aorta as a single trunk in 91%. Angiography showed that each principal bronchus was accompanied by 2 bronchial artery branches far into the lung parenchyma. The central branching pattern of the artery between the aorta and the principal bronchi was divided into 3 subtypes. Evans Blue showed communication with the whole mediastinum. The anatomical relations are described. It is concluded that the broncho-oesophageal artery divides to follow each bronchus with 2 bronchial branches. A nomenclature for these branches is suggested. The pig anatomy is suited for experimental investigations on the bronchial circulation.  (+info)

The porcine bronchial artery. Anastomoses with oesophageal, coronary and intercostal arteries. (6/114)

Information about the existence and anatomy of arterial anastomoses with the porcine bronchial artery is lacking in the literature. Prior to basic physiological investigations in a porcine model related to lung transplantation with bronchial artery revascularisation, this study was designed to examine the anatomy of systemic arterial anastomoses with the bronchial artery system. Twenty pigs were studied in 3 groups. In 2 groups the heart-lung block was removed with all mediastinal structures. One group served for investigation of coronary-bronchial artery anastomoses and one for investigation of oesophageal-bronchial artery anastomoses. The systemic arteries to be examined were cannulated. The inflated heart-lung block was examined macroscopically with Evans blue, and radiographically after contrast injection. In the 3rd group intercostobronchial artery anastomoses were studied radiographically with the heart-lung block in situ. Coronary-bronchial artery anastomoses were demonstrated in 3 of the 5 pigs with an aortic 'pouch' technique, but contrast was very limited in 2 of these 3. Oesophageal arterial anastomoses with bronchial arterial branches and/or the pulmonary veins were demonstrated in 6 of the 7 pigs and more markedly than the coronary-bronchial anastomoses. Intercostobronchial artery anastomoses could not be demonstrated angiographically. It was concluded that the existence of coronary-bronchial and oesophageal-bronchial artery anastomoses in the pig appear to establish an arterial net between the base of the heart and the distal oesophagus. The resemblance to human oesophageal-bronchial artery anastomoses supports use of a porcine model for experimental studies.  (+info)

Human bronchial artery blood flow after lung Tx with direct bronchial artery revascularization. (7/114)

The inaccuracy of measuring human bronchial artery blood flow has previously been considerable. En bloc double-lung transplantation with bronchial artery revascularization (BAR) using a single conduit offers the unique opportunity of direct measurement of the total bronchial artery blood flow. In eight en bloc double-lung-transplanted patients with complete BAR, the basal blood flow was measured by using a 0.014-in. Doppler guide wire and arteriography. The average peak velocity in the conduit was 12-73 cm/s [+/-2.1 (SD) cm/s], and the conduit diameter was 1.7-3.1 mm [+/-0.10 (SD) mm], giving individual basal flow values between 19 and 67 ml/min [+/-5 (SD) ml/min], or 0.2-1.9% of estimated cardiac output. In three patients basal measurements were followed by injection of nitroglycerin and verapamil into the conduit. This increased the bronchial artery flow to 121-262% of basal values (31-89 ml/min). The measured values appear more physiologically plausible than previous bronchial artery blood flow measurements in humans.  (+info)

Bronchial vasodilation evoked by increased lower airway osmolarity in dogs. (8/114)

Hyperosmotic saline solutions stimulate lower airway sensory nerves. To determine whether airway hyperosmolarity evokes neurally mediated changes in bronchial artery blood flow (Qbr), we measured the effect of injection of small volumes (1 ml) of hyperosmotic saline into a right lobar bronchus on Qbr of anesthetized, artificially ventilated dogs. In 14 dogs, hyperosmotic saline (1,200 and 2,400 mmol/l) increased Qbr by 58 +/- 12 (SE) and 118 +/- 12%, respectively, from a baseline of 8 +/- 2 ml/min. Qbr increased within 6-8 s of the injections, peaked at 20 s, and returned to control over 2-3 min. Isosmotic saline had minimal effects. In contrast, hyperosmotic saline decreased flow in an intercostal artery that did not supply the airways. The bronchial vasodilation was decreased by 72 +/- 11% after combined blockade of alpha-adrenoceptors and muscarinic cholinergic receptors and by 66 +/- 6% when the cervical vagus nerves were cooled to 0 degrees C. Blockade of H(1) and H(2) histamine receptors did not reduce the nonvagal response. We conclude that hyperosmolarity of the lower airways evokes bronchial vasodilation by both a centrally mediated reflex that includes cholinergic and adrenergic efferent pathways and by unidentified local mechanisms.  (+info)

The bronchial arteries are a pair of arteries that originate from the descending thoracic aorta and supply oxygenated blood to the bronchi, bronchioles, and connected tissues within the lungs. They play a crucial role in providing nutrients and maintaining the health of the airways in the respiratory system. The bronchial arteries also help in the defense mechanism of the lungs by delivering immune cells and participating in the process of angiogenesis (the formation of new blood vessels) during lung injury or repair.

Hemoptysis is the medical term for coughing up blood that originates from the lungs or lower respiratory tract. It can range in severity from streaks of blood mixed with mucus to large amounts of pure blood. Hemoptysis may be a sign of various underlying conditions, such as bronchitis, pneumonia, tuberculosis, cancer, or blood disorders. Immediate medical attention is required when hemoptysis occurs, especially if it's in significant quantities, to determine the cause and provide appropriate treatment.

Therapeutic embolization is a medical procedure that involves intentionally blocking or obstructing blood vessels to stop excessive bleeding or block the flow of blood to a tumor or abnormal tissue. This is typically accomplished by injecting small particles, such as microspheres or coils, into the targeted blood vessel through a catheter, which is inserted into a larger blood vessel and guided to the desired location using imaging techniques like X-ray or CT scanning. The goal of therapeutic embolization is to reduce the size of a tumor, control bleeding, or block off abnormal blood vessels that are causing problems.

An arteriovenous (AV) anastomosis is a connection or short channel between an artery and a vein that bypasses the capillary bed. In a normal physiological condition, blood flows from the arteries to the capillaries, where oxygen and nutrients are exchanged with the surrounding tissues, and then drains into veins. However, in an AV anastomosis, blood flows directly from the artery to the vein without passing through the capillary network.

AV anastomoses can occur naturally or be created surgically for various medical purposes. For example, they may be created during bypass surgery to reroute blood flow around a blocked or damaged vessel. In some cases, AV anastomoses may also develop as a result of certain medical conditions, such as cirrhosis or arteriovenous malformations (AVMs). AVMs are abnormal connections between arteries and veins that can lead to the formation of an AV anastomosis.

It is important to note that while AV anastomoses can be beneficial in certain medical situations, they can also have negative consequences if they occur inappropriately or become too large. For example, excessive AV anastomoses can lead to high-flow shunts, which can cause tissue damage and other complications.

Smoke inhalation injury is a type of damage that occurs to the respiratory system when an individual breathes in smoke, most commonly during a fire. This injury can affect both the upper and lower airways and can cause a range of symptoms, including coughing, wheezing, shortness of breath, and chest pain.

Smoke inhalation injury can also lead to more severe complications, such as chemical irritation of the airways, swelling of the throat and lungs, and respiratory failure. In some cases, it can even be fatal. The severity of the injury depends on several factors, including the duration and intensity of the exposure, the individual's underlying health status, and the presence of any pre-existing lung conditions.

Smoke inhalation injury is caused by a combination of thermal injury (heat damage) and chemical injury (damage from toxic substances present in the smoke). The heat from the smoke can cause direct damage to the airways, leading to inflammation and swelling. At the same time, the chemicals in the smoke can irritate and corrode the lining of the airways, causing further damage.

Some of the toxic substances found in smoke include carbon monoxide, cyanide, and various other chemicals released by burning materials. These substances can interfere with the body's ability to transport oxygen and can cause metabolic acidosis, a condition characterized by an excessively acidic environment in the body.

Treatment for smoke inhalation injury typically involves providing supportive care to help the individual breathe more easily, such as administering oxygen or using mechanical ventilation. In some cases, medications may be used to reduce inflammation and swelling in the airways. Severe cases of smoke inhalation injury may require hospitalization and intensive care.

Arteries are blood vessels that carry oxygenated blood away from the heart to the rest of the body. They have thick, muscular walls that can withstand the high pressure of blood being pumped out of the heart. Arteries branch off into smaller vessels called arterioles, which further divide into a vast network of tiny capillaries where the exchange of oxygen, nutrients, and waste occurs between the blood and the body's cells. After passing through the capillary network, deoxygenated blood collects in venules, then merges into veins, which return the blood back to the heart.

The pulmonary artery is a large blood vessel that carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation. It divides into two main branches, the right and left pulmonary arteries, which further divide into smaller vessels called arterioles, and then into a vast network of capillaries in the lungs where gas exchange occurs. The thin walls of these capillaries allow oxygen to diffuse into the blood and carbon dioxide to diffuse out, making the blood oxygen-rich before it is pumped back to the left side of the heart through the pulmonary veins. This process is crucial for maintaining proper oxygenation of the body's tissues and organs.

Angiography is a medical procedure in which an x-ray image is taken to visualize the internal structure of blood vessels, arteries, or veins. This is done by injecting a radiopaque contrast agent (dye) into the blood vessel using a thin, flexible catheter. The dye makes the blood vessels visible on an x-ray image, allowing doctors to diagnose and treat various medical conditions such as blockages, narrowing, or malformations of the blood vessels.

There are several types of angiography, including:

* Cardiac angiography (also called coronary angiography) - used to examine the blood vessels of the heart
* Cerebral angiography - used to examine the blood vessels of the brain
* Peripheral angiography - used to examine the blood vessels in the limbs or other parts of the body.

Angiography is typically performed by a radiologist, cardiologist, or vascular surgeon in a hospital setting. It can help diagnose conditions such as coronary artery disease, aneurysms, and peripheral arterial disease, among others.

An arterio-arterial fistula is an abnormal connection or passage between two arteries. Arteries are blood vessels that carry oxygen-rich blood from the heart to the rest of the body. Under normal circumstances, arteries do not directly communicate with each other; instead, they supply blood to capillaries, which then deliver the blood to veins.

An arterio-arterial fistula can result from various causes, including congenital defects, trauma, or as a complication of medical procedures such as arterial catheterization or surgical interventions. The presence of an arterio-arterial fistula may lead to several hemodynamic consequences, depending on the size, location, and chronicity of the communication. These can include altered blood flow patterns, increased pressure in the affected arteries, and potential cardiac complications due to volume overload.

Symptoms of an arterio-arterial fistula may vary widely, from being asymptomatic to experiencing palpitations, shortness of breath, fatigue, or even congestive heart failure in severe cases. The diagnosis typically involves imaging studies such as ultrasound, CT angiography, or MRI angiography to visualize the abnormal communication and assess its hemodynamic impact. Treatment options may include observation, endovascular interventions, or surgical repair, depending on the individual case.

Pulmonary circulation refers to the process of blood flow through the lungs, where blood picks up oxygen and releases carbon dioxide. This is a vital part of the overall circulatory system, which delivers nutrients and oxygen to the body's cells while removing waste products like carbon dioxide.

In pulmonary circulation, deoxygenated blood from the systemic circulation returns to the right atrium of the heart via the superior and inferior vena cava. The blood then moves into the right ventricle through the tricuspid valve and gets pumped into the pulmonary artery when the right ventricle contracts.

The pulmonary artery divides into smaller vessels called arterioles, which further branch into a vast network of tiny capillaries in the lungs. Here, oxygen from the alveoli diffuses into the blood, binding to hemoglobin in red blood cells, while carbon dioxide leaves the blood and is exhaled through the nose or mouth.

The now oxygenated blood collects in venules, which merge to form pulmonary veins. These veins transport the oxygen-rich blood back to the left atrium of the heart, where it enters the systemic circulation once again. This continuous cycle enables the body's cells to receive the necessary oxygen and nutrients for proper functioning while disposing of waste products.

"Bronchi" are a pair of airways in the respiratory system that branch off from the trachea (windpipe) and lead to the lungs. They are responsible for delivering oxygen-rich air to the lungs and removing carbon dioxide during exhalation. The right bronchus is slightly larger and more vertical than the left, and they further divide into smaller branches called bronchioles within the lungs. Any abnormalities or diseases affecting the bronchi can impact lung function and overall respiratory health.

I'm sorry for any confusion, but "Polyvinyl Alcohol" is not a medical term. It is a chemical compound used in various industrial and commercial applications, including the production of adhesives, paints, and medical devices. Polyvinyl Alcohol is a type of synthetic polymer made from the polymerization of vinyl acetate monomer, followed by alcoholysis to replace the acetate groups with hydroxyl groups.

In a medical context, Polyvinyl Alcohol might be used in certain medical devices or applications, such as contact lenses, eye drops, and drug delivery systems, due to its biocompatibility and resistance to protein absorption. However, it is not a term commonly used to describe a medical condition or treatment.

Splenic infarction is the death of splenic tissue due to blockage of its arterial supply or, less commonly, its venous drainage. This results in ischemia and necrosis of the affected portion of the spleen. The most common cause is embolism from a distant source such as atrial fibrillation, infective endocarditis, or malignancy. Other causes include splenic artery thrombosis, sickle cell disease, hematologic disorders, and trauma. Clinical presentation can vary widely, ranging from being asymptomatic to acute abdominal pain, nausea, vomiting, and fever. Diagnosis is often made with imaging studies such as ultrasound or CT scan. Treatment depends on the underlying cause and severity of symptoms, but may include anticoagulation, antibiotics, or surgical intervention in severe cases.

The mammary arteries are a set of blood vessels that supply oxygenated blood to the mammary glands, which are the structures in female breasts responsible for milk production during lactation. The largest mammary artery, also known as the internal thoracic or internal mammary artery, originates from the subclavian artery and descends along the inner side of the chest wall. It then branches into several smaller arteries that supply blood to the breast tissue. These include the anterior and posterior intercostal arteries, lateral thoracic artery, and pectoral branches. The mammary arteries are crucial in maintaining the health and function of the breast tissue, and any damage or blockage to these vessels can lead to various breast-related conditions or diseases.

A domestic sheep (Ovis aries) is not a medical term, but it is an animal species that humans keep and breed for a variety of purposes, including meat, wool, and milk production. While the term "sheep" may appear in medical contexts, such as in discussions of zoonotic diseases (diseases transmissible between animals and humans), the specific definition you are looking for is not medical in nature. Domestic sheep are social herbivores that prefer to eat short grasses and can be found in various parts of the world. They have been domesticated for thousands of years, making them one of the earliest animals to be domesticated by humans.

Bronchial neoplasms refer to abnormal growths or tumors in the bronchi, which are the large airways that lead into the lungs. These neoplasms can be benign (non-cancerous) or malignant (cancerous). Malignant bronchial neoplasms are often referred to as lung cancer and can be further classified into small cell lung cancer and non-small cell lung cancer, depending on the type of cells involved.

Benign bronchial neoplasms are less common than malignant ones and may include growths such as papillomas, hamartomas, or chondromas. While benign neoplasms are not cancerous, they can still cause symptoms and complications if they grow large enough to obstruct the airways or if they become infected.

Treatment for bronchial neoplasms depends on several factors, including the type, size, location, and stage of the tumor, as well as the patient's overall health and medical history. Treatment options may include surgery, radiation therapy, chemotherapy, or a combination of these approaches.

Hemothorax is a medical condition characterized by the presence of blood in the pleural space, which is the area between the lungs and the chest wall. This accumulation of blood can occur due to various reasons such as trauma, rupture of a blood vessel, or complications from lung or heart surgery.

The buildup of blood in the pleural space can cause the affected lung to collapse, leading to symptoms such as shortness of breath, chest pain, and cough. In severe cases, hemothorax can be life-threatening if not promptly diagnosed and treated. Treatment options may include chest tube drainage, blood transfusion, or surgery, depending on the severity and underlying cause of the condition.

Lung transplantation is a surgical procedure where one or both diseased lungs are removed and replaced with healthy lungs from a deceased donor. It is typically considered as a treatment option for patients with end-stage lung diseases, such as chronic obstructive pulmonary disease (COPD), cystic fibrosis, idiopathic pulmonary fibrosis, and alpha-1 antitrypsin deficiency, who have exhausted all other medical treatments and continue to suffer from severe respiratory failure.

The procedure involves several steps, including evaluating the patient's eligibility for transplantation, matching the donor's lung size and blood type with the recipient, and performing the surgery under general anesthesia. After the surgery, patients require close monitoring and lifelong immunosuppressive therapy to prevent rejection of the new lungs.

Lung transplantation can significantly improve the quality of life and survival rates for some patients with end-stage lung disease, but it is not without risks, including infection, bleeding, and rejection. Therefore, careful consideration and thorough evaluation are necessary before pursuing this treatment option.

An aneurysm is a localized, balloon-like bulge in the wall of a blood vessel. It occurs when the pressure inside the vessel causes a weakened area to swell and become enlarged. Aneurysms can develop in any blood vessel, but they are most common in arteries at the base of the brain (cerebral aneurysm) and the main artery carrying blood from the heart to the rest of the body (aortic aneurysm).

Aneurysms can be classified as saccular or fusiform, depending on their shape. A saccular aneurysm is a round or oval bulge that projects from the side of a blood vessel, while a fusiform aneurysm is a dilated segment of a blood vessel that is uniform in width and involves all three layers of the arterial wall.

The size and location of an aneurysm can affect its risk of rupture. Generally, larger aneurysms are more likely to rupture than smaller ones. Aneurysms located in areas with high blood pressure or where the vessel branches are also at higher risk of rupture.

Ruptured aneurysms can cause life-threatening bleeding and require immediate medical attention. Symptoms of a ruptured aneurysm may include sudden severe headache, neck stiffness, nausea, vomiting, blurred vision, or loss of consciousness. Unruptured aneurysms may not cause any symptoms and are often discovered during routine imaging tests for other conditions.

Treatment options for aneurysms depend on their size, location, and risk of rupture. Small, unruptured aneurysms may be monitored with regular imaging tests to check for growth or changes. Larger or symptomatic aneurysms may require surgical intervention, such as clipping or coiling, to prevent rupture and reduce the risk of complications.

Bronchiectasis is a medical condition characterized by permanent, abnormal widening and thickening of the walls of the bronchi (the airways leading to the lungs). This can lead to recurrent respiratory infections, coughing, and the production of large amounts of sputum. The damage to the airways is usually irreversible and can be caused by various factors such as bacterial or viral infections, genetic disorders, immune deficiencies, or exposure to environmental pollutants. In some cases, the cause may remain unknown. Treatment typically includes chest physiotherapy, bronchodilators, antibiotics, and sometimes surgery.
