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)

OBJECTIVE: To study the long-term outcome, safety, and complications of bronchial artery embolization (BAE) in the treatment of patients with massive hemoptysis.. METHODS: A retrospective analysis of 232 cases of massive hemoptysis treated with BAE from February 2000 to February 2009 in our hospital was carried out. All cases were followed by repeated X-ray or CT examination, telephone calls, or questionnaires, with the longest period up to 9 years.. RESULTS: There were 627 blood vessels which were totally embolized by 741 coils for the 232 cases. The hemoptysis was stopped instantly in 100% of the patients. 91.8% (213/232) of the cases were cured and 19 cases (19/232, 8.18%) were improved. The overall effective rate was 100% (232/232). No serious or delayed complications occurred. None of the patients died.. CONCLUSION: Bronchial artery embolization is effective in cases with massive hemoptysis for its immediate effect and safety. ...

Bronchial blood flow markedly increases immediately after inhalational injury. This study examines whether the ablation of the bronchial artery attenuates pathophysiological changes and improves survival after burn and smoke-inhalational injury in an ovine model. Acute lung injury was induced by 40% total body surface-area third-degree cutaneous burn and cotton smoke inhalation (48 breaths of cotton smoke, ,40 °C) under deep anaesthesia. Twelve adult female sheep were divided into two groups: (1) sham (injured, non-ablated bronchial artery, n = 6); (2) ablation (injured, ablated bronchial ...

Figure 3d: DSA image shows hypertrophied right bronchial artery with pulmonary arterial shunting. Embolization of this artery was achieved with PVA.. CTPA that was done at the same time as the CXR showed mediastinal lymphadenopathy encasing the right pulmonary artery and resultant narrowing. No systemic collaterals could be seen on this study (Figs. 3b and 3c). However, flush aortic angiogram did reveal hypertrophied right bronchial artery with pulmonary arterial shunting (Fig. 3d). Embolization of the artery was achieved with PVA particles 500 µ. The patient had a temporary relief for two months; but she later suffered a massive bout of hemoptysis to which she succumbed.. Discussion. Chronic pulmonary artery narrowing may result from diverse causes like congenital, infectious, inflammatory and chronic thromboembolism.1 Infectious causes account for the majority of cases in our setting. This is due to a high prevalence of tuberculosis in India. Narrowing of pulmonary artery in the setting of ...

The effects of bronchial arterial administration of vasoactive substances on the pulmonary circulation were studied by a new technique for selective catheterization of a bronchial artery in intact dogs. In most experiments, this technique permitted pressor agents to be distributed mainly to one lung with smaller amounts to the other lung. The intercostal arteries were avoided, and in all but 2 of 23 experiments only microscopic quantities of injected India ink could be identified in the distribution of the esophageal and mediastinal branches. These studies indicate that serotonin, angiotensin, histamine, and norepinephrine injected selectively into a bronchial artery increase lobar arterial pressure. Since blood flow was constant and left atrial pressure did not change, the increase in pressure suggests active pulmonary vasoconstriction. Additionally, the responses to bronchial and lobar arterial injections of pressor agents were similar. The contribution of bronchopulmonary shunt flow to ...

The contrast enhancement of the heart and lung after intravenous injection follows certain anatomical rules. First the right atrium (video 1, RA), right ventricle (video 1, RV), pulmonary artery, lung parenchyma (video 2, LUNG) and pulmonary veins are enhancing followed by the left atrium (video 1, LA), left ventricle (video 1, LV), coronary arteries & myocardium (video 1, MYO), aorta (video 2, AORTA), bronchial arteries (BA) and the systemic vessels (video 2 including hepatic arteries, portal venous system and liver parenchyma). In other words the venous blood from the heart to the lung parenchyma is featured, which is mandatory for the gaseous exchange. Thereafter, the systemic arterial vascular system is enhancing. In the lung the analysis of the dual blood supply allows the differentiation of lung emboli (pulmonary artery vascular supply followed by pulmonary vein washout) and neoplasia (bronchial artery vascular supply followed by bronchial vein washout). In the liver the dual blood supply ...

Optimal lung preservation via flush of the pulmonary vasculature minimizes early graft failure post-lung transplantation. We hypothesized that the route of pulmonary flush has differential effects on thermal gradients in the lung and expression of inflammatory mediators. Swine underwent antegrade flush (AG) via pulmonary artery; AG/RG: antegrade + retrograde flush via pulmonary veins or AG/BA: antegrade + bronchial artery flush via bronchial artery. Temperatures were recorded in bronchial mucosa and peribronchial lymph nodes. RT-PCR was utilized to detect cytokine gene expression in the nodes. AG/BA flush resulted in greatest cooling of bronchial mucosa and lymph nodes (p < 0.001). The route of flush did not affect expression of RANTES, MCP-1, IL-8, IL-1, TNF-α or IL-6. However, expression of Gro was reduced 4-h post-preservation in all groups. Only AG/BA resulted in decreased IFN- transcripts. These data show that, compared to AG or AG/RG, AG/BA flush results in the greatest cooling of ...

The unpredictable and potentially lethal course of massive haemoptysis requires prompt resuscitation, airway protection, and correction of coagulopathy. Early investigation with bronchoscopy is recommended for localisation and control of bleeding by the application of topical adrenaline, balloon tamponade, or selective lung intubation. There is increasing acceptance of bronchial artery embolisation as the treatment of choice for acute massive haemoptysis not controlled by conservative treatment, when a bronchial artery can be identified as the source of bleeding. Surgical resection remains the treatment of choice for particular conditions where the bleeding site is localised and the patient is fit for lung resection.. ...
Massive haemoptysis is a medical emergency. If you think someone is experiencing massive haemoptysis, then call 999 for an ambulance.. A person with massive haemoptysis needs to be admitted to hospital and a tube may need to be placed into their throat to assist them with their breathing.. A procedure called a bronchial artery embolisation (BAE), carried out by specialist radiology doctors, will then be required to stop the bleeding. During a BAE, a special dye is injected into your arteries so they show up clearly on X-rays.. Then, using X-ray scans as a guide, the source of the bleeding is located and injected with tiny particles, around the size of a grain of sand, that will help clog the vessel up and stop the bleeding. ...
Robert Hyland, MD, FRCPC, Division of Respirology, Department of Medicine, St. Michaels Hospital, University of Toronto, Toronto, ON. Hemoptysis is an important clinical problem that is especially ominous when seen in older patients. The main causes of hemoptysis in first world nations are bronchogenic carcinoma, bronchitis, and bronchiectasis. In older patients cancer remains the main concern, especially if there is a smoking history. The diagnostic approach to nonmassive hemoptysis starts with a chest x-ray, followed by a CT scan and then fibre optic bronchoscopy, which is well tolerated by older adults. In massive hemoptysis, chest x-ray is usually followed immediately by fibre optic or rigid bronchoscopy. Older patients require closer monitoring due to poor cardiopulmonary reserve; management options include endoscopic interventions, bronchial artery embolization ...

TY - JOUR. T1 - Role of the bronchial circulation in ischemia-reperfusion lung injury. AU - Pearse, D. B.. AU - Wagner, E. M.. PY - 1994/1/1. Y1 - 1994/1/1. N2 - Bronchial arterial (BA) perfusion could modify pulmonary arterial (PA) ischemia-reperfusion (IR) injury by promoting clearance of peribronchial edema or limiting edema formation through maintenance of pulmonary vessel integrity via bronchopulmonary anastomotic or pulmonary vasa vasorum flow. The purpose of this study was to determine the effect of BA perfusion on IR injury in isolated sheep lungs. In 12 lungs (BA++) the BA was perfused throughout 30 min of PA ischemia and 180 min of reperfusion. In 12 lungs (BA- +) BA perfusion was begun with PA reperfusion, and in 15 lungs (BA--) the BA was never perfused. After 180 min, extravascular lung water was less (P , 0.05) in BA++ and BA-+ lungs [4.70 ± 0.16 and 4.57 ± 0.18 g/g blood-free dry lung (bfdl)] than in BA-- lungs (5.23 ± 0.19 g/g bfdl). The reflection coefficient for albumin was ...
The root of the lung is located at the hilum of each lung, just above the middle of the mediastinal surface and behind the cardiac impression of the lung. It is nearer to the back (posterior border) than the front (anterior border). The root of the lung is connected by the structures that form it to the heart and the trachea. The rib cage is separated from the lung by a two-layered membranous coating, the pleura. The hilum is the large triangular depression where the connection between the parietal pleura (covering the rib cage) and the visceral pleura (covering the lung) is made, and this marks the meeting point between the mediastinum and the pleural cavities. The root is formed by the bronchus, the pulmonary artery, the pulmonary veins, the bronchial arteries and veins, the pulmonary plexuses of nerves, lymphatic vessels, bronchial lymph nodes, and areolar tissue, all of which are enclosed by a reflection of the pleura. The root of the right lung lies behind the superior vena cava and part of ...
A more severe hemoptysis can be seen with the expectoration of clots after a vigorous coughing episode. It is surprising how many patients will continue to downplay the significance of more severe episodes of hemoptysis or fail to seek urgent medical attention. The expectoration of clots is not considered pathognomonic for lung cancer. Massive hemoptysis (by definition, >200 mL per day), although less common with lung cancer, can occur in up to 20% of patients in whom lung cancer is the cause.4 Furthermore, it has been reported to be fatal in up to 50% of patients with lung cancer and demands serious and immediate attention in a hospital setting.5 ...
Bronchiectasis is subdivided into specific types based on the pathologic or radiographic appearance of the airways (Fig. 94-1). Cylindrical or tubular bronchiectasis is defined by dilated, slightly tapered airways and often is seen in patients with tuberculosis infections. Varicose bronchiectasis resembles the chronic venous state of the same name, with areas of dilatation and narrowing. Saccular or cystic bronchiectasis is characterized by progressive dilatation of the airways which end in sac-like cystic structures that resemble a cluster of grapes. This subtype is more common after obstruction or bacterial infection. Regardless of the subtype, thick mucoid secretions often are seen pooled in the dilated airways causing a chronic, transmural inflammatory state involving the wall of the airway. Lung parenchyma distal to the dilated, ectatic airways is often damaged as well, with fibrosis and emphysematous changes present. The accompanying bronchial circulation and lymph nodes may be engorged ...
Hemoptysis is the coughing up of blood from the respiratory tract. The blood can come from the nose, mouth, throat, the airway passages leading to the lungs, or the lungs. In a healthy nonsmoker, it usually indicates a mild infection and is generally no cause for concern. In patients at risk for lung disease, however, hemoptysis is often a sign of serious illness, including tuberculosis, bronchitis or lung cancer.

Since lung can obtain its oxygen from from the alveolar gas and has a second blood supply through the bronchial arteries, occlusion of a pulmonary artery does not usually produce tissue necrosis.. Due to dual blood supply and free anastomosis between the pulmonary capillaries, small emboli fail to cause any infarction in a healthy lung.. Tissue distal to the obstructed artery may be normal or merely show congestion, hemorrhage, and intra-alveolar fibrin with intact alveolar walls. However, inspite of the dual blood supply, from bronchial and pulmonary vessels, pulmonary infarction is very common.. Embolus arising in any part of systemic circulation has to pass through the lungs.. Infarction is common when the circulation of the lung is slowed down associated with increased pulmonary circulatory pressure - Example: In chronic passive venous congestion, hypostatic congestion as seen in post-operative and post-natal period. Under such condition, when branch of pulmonary artery is blocked , force of ...
A young woman presented with recurrent hemoptysis temporally associated with menstruation.

The use of progesterone suppressed menstruation and hemoptysis during four months of treatment. Chest x-ray was normal.
OBJECTIVE: Occult pulmonary foreign bodies are infrequently seen in adults. Patients present with cough, dyspnea and recurrent hemoptysis mimicking asthma, chronic bronchitis and lung cancer and usually reach the thoracic surgeon for diagnosis.. MATERIAL: During the last 10 years 6 patients, 5 male and one female, ranging in age from 36 to 74 years, were admitted to our departments with the suspicion of lung cancer. None of our patients had a history of aspiration or psychiatric disease. All patients had recurrent pneumonitis for more than 4 years, additionally, 3 of them presented with hemoptysis and chronic cough. All of them were submitted to repeated bronchoscopies that did not turn out to be diagnostic. Also FNA under CT guidance did not solve the problem of preoperative diagnosis.. RESULTS: All patients after a detailed staging were led to the operating room and were submitted to thoracotomy. The intraoperative histological diagnosis revealed fibrotic and necrotic tissue in the majority of ...

This project seeks to evaluate the effectiveness of a new post-operative pain relief program for women who have undergone uterine artery embolisation (UAE).. UAE is performed by an interventional radiologist as a treatment of uterine fibroids (non-cancerous growths of the uterus.) UAE can be associated with a high level of post-procedural pain and it is the purpose of this study to evaluate a new relief regimen for dealing with this acute pain.. There will be two treatment groups into which patients will be randomly assigned. One will receive the current post-operative therapy (dose-on-demand) and the other will receive the new therapy (pre-emptive dosing). Otherwise patients will receive standard management protocol for this procedure. Only patients that are scheduled for UAE will be enrolled (up to 40 patients).. The new treatment involves giving the patient their morphine dose orally and sixty minutes before the procedure begins (pre-emptive dosing) as opposed to current standard treatment ...
All patients with massive haemoptysis should be monitored in an intensive care unit (ICU) or high dependency unit (HDU) and the patients fitness for surgery established. Attempts should be made to determine the side of bleeding and the patient positioned with the bleeding side down to prevent aspiration into the unaffected lung. Blood loss should be treated with volume resuscitation, blood transfusion, and correction of coagulopathy. If large volume bleeding continues or the airway is compromised, the patients trachea should be intubated with as large an endotracheal tube as is possible to allow adequate suctioning and access for bronchoscopy.2 If the bleeding can only be localised to the right or left lung, unilateral lung intubation may protect the non-bleeding lung.23 For right sided bleeding a bronchoscope may be directed into the left main bronchus which can then be selectively intubated over the bronchoscope with the patient lying in the right lateral position (fig 4). The left lung is ...

Massive hemoptysis is described in many disease processes. However, a mediastinal teratoma is rarely considered in a patient presenting with massive hemoptysis. Since a mediastinal teratoma has no specific symptoms, its definitive diagnosis is difficult before surgical intervention. Flexible bronchoscopy can be diagnostic in cases of a mediastinal teratoma with involvement of the bronchial tree. We report 2 cases of hemoptysis caused by mediastinal teratoma with bronchial communication. ...

Young-soo Bae is a pitcher with the Samsung Lions. He is a former Korea Baseball Organization MVP and represented South Korea in the 2006 World Baseball Classic. Bae made his debut in the KBO with the Samsung Lions on April 9, 2000 against the LG Twins. He went 0-2 with a 6.75 ERA that season. In 2001, Young-soo was 13-8 with a 3.77 ERA at age 20. One sore spot was control as he walked 89 in 169 2/3 innings. The control issue really flared up when he plunked KBO OPS leader Felix Jose, who charged the mound, leading to a season-ending suspension. In 2002, the young right-hander had a 6-7, 5.53 mark with 43 BB in 81 1/3 innings. His control improved slightly in 2003 (77 BB in 163 2/3 IP) and he went 13-5 with a 4.51 ERA. He allowed over a hit per inning as well but did finish 7th in the Korea Baseball Organization in strikeouts (99). Bae became a star in 2004 with a 17-2, 2.61 campaign. He still walked 74 in 189 2/3 innings but struck out 144 and allowed 163 hits and only 6 home runs. He led the ...
