Pulmonary arteriovenous malformations (PAVMs) can be associated with life-threatening complications such as paradoxical embolization, cerebral abscess, and hemothorax. Therefore, all adults with PAVMs should be offered treatment. Percutaneous transcatheter embolization is the first-line treatment, but 5-25% of cases require further treatment due to persistence after embolization. Recently, the role of minimally invasive thoracic surgery as a definitive treatment has been evaluated. We describe a case of a small peripheral PAVM causing hemothorax, which was safely treated with video-assisted thoracoscopic surgery (VATS). In our case, the PAVM appeared to protrude into the pleural cavity on chest computed tomography (CT), perhaps explaining why it led to a hemothorax. A 64-year-old man with a history of a brain abscess, for which he underwent surgery 6 months previously, developed a left-sided hemothorax. He had experienced recurrent epistaxis and received anticoagulation therapy for chronic atrial
In a patient undergoing regular hemodialysis through an arteriovenous fistula access, pleural effusion is a known long term complication. However, a unilateral hemothorax is relatively uncommon. Here we report a 46 year old male, end-stage renal disease patient, on maintenance hemodialysis, who presented with a giant brachiocephalic AV fistula in his left arm and progressive breathlessness. Radiological imaging revealed a left sided pleural effusion. Ultrasound guided aspiration revealed a hemorrhagic pleural fluid. A Doppler study of the fistula revealed a high velocity blood flow through the fistula, thereby establishing the cause of the unilateral hemothorax. Ligation of the fistula resulted in complete resolution of the hemothorax. The other possible causes for hemothorax in a dialysis patient are also discussed in this case report.
Hemorrhagic complications are recognized when anti-platelet agents are used during or after surgical procedures. We present a 69-year-old male patient who developed hemothorax after chest tube insertion for pneumothorax as a complication of clopidogrel and aspirin following ischemic heart disease. Hemothorax associated clopidogrel has rarely been reported and this is the first academic publication of this complication type following chest tube insertion shortly after the cessation of clopidogrel. Our case demonstrates the possibility of hemothorax when chest tube insertion is indicated under such conditions ...

Technical results, clinical efficacy and predictors of outcome of intercostal arteries embolization for hemothorax: a two-institutions experience
Rationale:. Neurofibromatosis type I (NF1) is a hereditary neurocutaneous syndrome resulted from the mutation in NF1 gene. The clinical diagnosis is comprehensively made by neurofibroma, Café-au-lait spot, osseous deformity and so on. Infrequently, aberrant neurofibromin function results in vasculopathy, which can cause fatal hemorrhage. However, it is unclear how surgical interventions should be made.. Case 1:. A 53-year-old man with NF1 was admitted for sudden chest pain. Computed tomography revealed left hemothorax and a tumorous aneurysm in the 7th intercostal artery. A thoracic drainage was performed immediately, and a thoracotomy was performed on 18 days after admission.. Case 2:. A 32-year-old man with NF1 was admitted due to chest back pain and hemodynamic instability. Computed tomography revealed left massive hemothorax and an extravasation from the 9th intercostal aneurysm. An urgent operation via left lateral thoracotomy was performed to remove hematoma and control active bleeding. ...

Primary evaluation: In primary assessment of chest trauma patients the process of diagnosis and prompt treatment should be started simultaneously, searching and managing life-threatening lesions such as airway obstruction, tension pneumothorax, open pneumothorax, massive hemothorax, flail chest and cardiac tamponade. It is mandatory to monitor ECG, blood pressure, pulse oximetry and capnography. In this primary evaluation chest X-ray, ultrasound and blood gases are taken and decide whether to intubate the trachea, needle thorachostomy, chest tube thoracotomy in the emergency room, and/or pericardiocentesis. Secondary assessment: Once the life-threatening lesions are identified and treated a more extend and meticulous evaluation must be done. The first step is to make a complete and detailed review of the case. If there are relatives or friends we must obtain complete data of the patients medical history that can be relevant for the immediate comprehensive management: diabetes, hypertension, ...
Internal jugular vein (IJV) catheterization is a frequently performed procedure. Amongst others, IJV is increasingly being used as a temporary route for hemodialysis catheter placement in patients with renal failure, as is thought to be safer than subclavian or femoral vein sites. In the vast majority of cases, IJV cannulation is successful and uncomplicated, but some times may be associated with potentially serious traumatic complications such as inadverted arterial puncture or laceration, pleural and mediastinal injuries, pneumothorax, hemothorax and hemomediastinum. Arterial injury can result in the development of hematoma, hemothorax, pseudoaneurysm or arteriovenous fistula 5678 . These complications usually occur subsequently to arterial catheterization rather than arterial puncture alone. When identified, prompt vascular surgery and radiology consultation is required.. The most common arterial injury associated with IJV cannulation is carotid artery puncture. Complications caused by ...

Background: Epicardial catheter ablation has been shown to be an effective strategy for treating ventricular arrhythmias (VA). We investigated the efficacy and safety from a tertiary referral center in Taiwan. Methods: From 2010 to 2016, patients undergoing epicardial ablation for VAs were consecutively enrolled. The clinical characteristics, disease entity, electrophysiological studies, and ablation outcome were extracted for further analysis. Results: A total of 80 patients were eligible, including 34 patients for arrhythmogenic right ventricular cardiomyopathy (ARVC), 16 for Brugada syndrome (BrS), 13 for idiopathic VAs, 11 for idiopathic dilated cardiomyopathy (IDCM), 2 for ischemic cardiomyopathy, and 4 for other nonischemic cardiomyopathies (NICM ...
A 51-years-old, male with known history of type 2 diabetes mellitus admitted with evidence of bilateral renal stone for left PCNL. IVU revealed right and left renal stone of about 3cm and 1.1cm respectively, with no evidence of hydronephrosis. Laboratory investigation exhibited hemoglobin of 12.4g/dl. Urine culture and sensitivity was negative and the patient underwent left PCNL (retrograde approach -Lawson).The patient developed left hemothorax and intercostal tube (ICT) was placed. On Post PCNL day 5, follow up CT scan (chest and abdomen) revealed about 8.6 cm3 pleural collection of blood and left lower calyceal stone around 0.9 cm. Hematological examination showed reduced hemoglobin of 9g/dl. On post PCNL day 7, we observed that ICT was still draining blood and hemoglobin further dropped to 8.5g/dl. Two units of PRBCs were transfused and IV rFVIIa was given in a dose of (60 µg/kg) once. On the next day hemoglobin raised to 10.3g/dl and subsequently improved to reach 11gm/dl on the following ...
BACKGROUND: The 25% of traumatic deaths are due to chest trauma with a mortality of 28%, and closed trauma is the most common mechanism of injury. The use of firearms increases the relative risk of death. The five more frequent specific chest injuries are lung contusion (31.8%), hemothorax/pneumothorax (19.4%), rib fractures (13.2%), and diaphragmatic injury (7.5%). CLINICAL CASE: Patient of 25 years with a single firearm projectile wound in the chest who assisted to the emergency room (ER) with significant respiratory distress and meriting surgical emergency airway, documenting double pneumothorax, aortic laceration and rupture of the trachea, which required management in the ER with bilateral chest tube placement and subsequent surgical repair ...
EPH most commonly occurs in high-energy blunt trauma, especially those involving rib fractures [1]. Diagnosis of EPH is generally difficult and often delayed and is mainly based on x-ray findings; therefore, a thoracic CT scan is usually conducted to generate a diagnosis at the shortest possible time. A typical CT finding in EPH is the "fat sign," which is the displacement of the thoracic soft-tissue band medially to the ribs due to a fluid accumulation in the extrapleural space [2]. A stable patient and a small hematoma can be managed conservatively. Evacuation of blood clots is required in large EPHs because respiratory and circulatory disturbances may occur [3].. Hemothorax may also occur in EPH cases due to coagulopathy during hemodialysis, suggesting that it arises secondary to platelet dysfunction of uremia and/or anticoagulant use. Nevertheless, the incidence of unilateral EPH is relatively rare in this situation [4]. In the present report, the patient underwent anticoagulant medication ...
This leads to the "Summary and Interpretation." The summary is inconclusive and there is no interpretation. The medical examiner explains that Reginald Daye sustained a single puncture laceration that penetrated a slew of organs in the thoracic and abdominal cavities, with hemorrhaging into them. It is evident that Daye did not die due to shock or blood loss. If there was a hemothorax, or bleeding into the chest cavity, or pneumothorax, air in the thoracic cavity, a chest tube would have been inserted. Repairs to lacerated organs should have put an end to the bleeding into the abdominal cavity. There is no mention as to why Daye was brain dead, why he went into cardiac arrest, which preceded which, and whether or not the patient was taken off life support. These questions are all the more baffling when it was reported post-operatively that he was expected to make a full recovery ...
The new H*VENT vented chest dressing treats not only pneumothorax, but also allows fluids such as blood to be released from the chest (hemothorax).
AP:No evidence of pneumothorax or hemothorax. Multiple diffuse nodules ranging from 2-4 cm in diameter found bilaterally. There is evidence of some widening of the mediastinum. There are bilateral diffuse areas of greater opacity, greater in the mid to lower fields. L heart border is not clearly seen, both costaphrenic angles are not clearly visualized. Lat: Diffuse increased opacity throughout lung fields, to include above and below the heart shadow. CPA is completely obscured, unable to visualize the spinous processes clearly.
Results. The pleura damage during the operation was registered in 4 (5,2%) patients. Non-specific complications such as hemothorax (n=1) and wound bleeding after surgery with festering it further (n=1) have been occurred. In the postoperative period the brachial plexitis manifested by pain in the arm and neck regions which was stopped with anti-inflammatory, anesthetic agents was observed in 3 patients. All above-mentioned complications were transient in 9 (11,7%) patients. The gradual regression of the neurological symptoms and arterial disturbances was noticed. In the long-term period the positive results were registered in all operated patients, the certain symptoms were recurred in some of them in winter season ...

Hemopneumothorax, or haemopneumothorax, is a medical term describing the combination of two conditions: pneumothorax, or air in the chest cavity, and hemothorax (also called hæmothorax), or blood in the chest cavity.. A hemothorax, pneumothorax or both can occur if the chest wall is punctured. To understand the ramifications of this it is important to have an understanding of the role of the pleural space. The pleural space is located anatomically between the visceral membrane, which is firmly attached to the lungs, and the parietal membrane which is firmly attached to the chest wall (aka ribcage and intercostal muscles, muscles between the ribs). The pleural space contains pleural fluid. This fluid holds the two membranes together by surface tension, as much as a drop of water between two sheets of glass prevents them from separating. Because of this, when the intercostal muscles move the ribcage outward, the lungs are pulled out as well, dropping the pressure in the lungs and pulling air into ...
Nickles x-rays and case were reviewed by a boarded radiologist, a neurologist, and a surgeon. He was sent for BOTH a CT and an MRI. From these he was found to have both a mass on his heart that extended up and around his spine. These were causing his neurologic (weakness in the back legs) signs, and the blood in his chest. He had an extensive, and expensive, work-up. I have to admit that in 10 years of practice I have never seen a case worked up this extensively, nor this completely, nor this complicated. Nickle had a surgery on the mass around his spine to provide a diagnosis of the mass in his chest. To provide a treatment to a condition it must be diagnosed. The best way to do this is with tissue. Nickles surgery was performed to try to remove the mass on his spine, to help reduce the paralysis in his back legs, and tailor a treatment plan for his specific tumor. His mass came back as a hemangiosarcoma. These are aggressive, invasive and very difficult, if not impossible, to remove. Nickles ...
TY - JOUR. T1 - Early autologous fresh whole blood transfusion leads to less allogeneic transfusions and is safe. AU - Rhee, Peter. AU - Inaba, Kenji. AU - Pandit, Viraj. AU - Khalil, Mazhar.

N2 - BACKGROUND: The practice of transfusing ones own shed whole blood has obvious benefits such as reducing the need for allogeneic transfusions and decreasing the need for other fluids that are typically used for resuscitation in trauma. It is not widely adopted in the trauma setting because of the concern of worsening coagulopathy and the inflammatory process. The aim of this study was to assess outcomes in trauma patients receiving whole blood autotransfusion (AT) from hemothorax. METHODS: This is a multi-institutional retrospective study of all trauma patients who received autologous whole blood transfusion from hemothorax ...
A 71-year-old woman presented with a 1-week history of dyspnoea, right pleuritic chest pain and bilateral ankle oedema. There was no history of cough, fever or haemoptysis. Her body mass index was ,30. Her jugular venous pressure was raised with reduced air entry over the right lung base. She was anaemic (haemoglobin 6.8 g/dl, mean corpuscular volume 67) with type II respiratory failure (pH 7.40, oxygen tension 9.30 kPa, carbon dioxide tension 9.32 kPa on 0.5 fraction of inspired oxygen). Chest radiography revealed a moderate right pleural effusion. A chest drain was inserted in the emergency room and 2 litres of bloody effusion was drained. A subsequent contrast-enhanced CT scan of the chest revealed a probable pulmonary arteriovenous malformation (PAVM) in the right lower lobe and a compressing organised haemothorax with significant mediastinal shift (fig 1A). Pulmonary angiography confirmed a massive PAVM with multiple large feeding arteries and other smaller PAVMs in the right lower lobe ...
From January 1989 to December 1992, in the Institute of Clinical Surgery of the University of Perugia, 102 patients were admitted for thoracic trauma. Two patients with an open thoracic trauma, both presenting multiple shot-wounds, underwent an explorative thoracotomy. One of them died on the operating-table from hemorrhage, while the other was saved by a wedge-resection. A 3rd explorative thoracotomy was successfully performed on a patient with internal thoracic trauma and severe hemothorax. Among the 100 patients with an internal thoracic trauma, mortality was 6%, but only one of the 6 deceased, had no lesions other than a fail chest. As a matter of fact 38 patients presented lesions in other parts of the body. Simple and complicated multiple costal fractures, found in 84 cases, were the most frequent lesions observed. Seventeen of the 38 patients with pneumothorax and/or pleural effusion had a chest tube applied. Three patients were operated for a diaphragmatic hernia with a positive outcome. ...
Rib fractures are the most common chest injury accounting for 10 to 15 percent of all traumatic injuries in the U.S. Nearly 300,000 people are seen each year for rib fractures and 7 percent of this population will require hospitalization for medical, pain, and/ or surgical management.. Rib fractures can cause serious complications including: bleeding in the chest (hemothorax), collapse of the lung (pneumothorax), or result in a fluid accumulation in the chest (pleural effusion), just to name a few. As well, rib fractures may contribute to the development of a lung infection or pneumonia. These problems are important to diagnose following chest trauma and even more importantly, when present, they need to be followed closely in the early post-traumatic period.. The most common symptom that people experience with rib fractures is..... ...
A 28-year-old man with multiple gunshot wounds to the chest and upper extremities was transported by private vehicle to a community hospital with limited trauma capabilities. On arrival he developed pulseless electrical activity and cardiopulmonary resuscitation was initiated. He was intubated, transfused with 4 units of packed red blood cells, and resuscitated with 2 L of crystalloid prior to regaining spontaneous circulation. Left-sided tube thoracostomy immediately drained 1600 mL of bright red blood. He was transiently stable for a short transport to the nearest level 1 trauma center.. On arrival the patient was normotensive with tachycardia. Chest X-ray demonstrated persistent left-sided hemothorax despite a well-positioned chest tube. Focused Assessment with Sonography for Trauma (FAST) examination was negative for pericardial fluid, but positive for intra-abdominal fluid. During the secondary examination the patient became hypotensive with systolic blood pressure (SBP) in the 70 s. A ...

This is a view of the diaphragm and Liver interface. You should notice a bright white echogenic line of the diaphragm around the liver - above which is the pleural space, and below is the Liver. You should appreciate a mirror image artifact of the liver above the diaphragm when there is no thoracic fluid. Pleural effusions (and hemothorax) will appear black above the diaphragm (without a mirror image artifact) and the spine shadows will also be seen extending beyond the diaphragm as fluid allows its visualization. Look between the diaphragm and the liver for any intraperitoneal free fluid as (although rare) fluid may only be located here depending on the location of the laceration ...
This really is scary because if you got hit that badly there is probably all kinds of internal damage to your lungs as well. The flail chest itself is not the life-threatening part of the problem -- it can be stabilized with bandages and will heal itself as any broken ribs will.

Clinical suspicion for the presence of pulmonary AVM should arise when there is the presence of nonspiculated pulmonary nodule suggestive of AVM; a family history of hereditary hemorrhagic telangiectasia; sequelae of right-to-left shunting such as hypoxemia, dyspnea, clubbing, cyanosis, and polycythemia; and systemic embolism such as cerebral stroke or cerebral abscess. Epistaxis can be reported in up to 85% of patients with hereditary hemorrhagic telangiectasia.1 A continuous bruit can be auscultated over the lesion. The triad of cyanosis, clubbing, and polycythemia is seen in 20% of patients. Approximately 90% of AVMs are unilateral, and 50% to 67% of patients have a single AVM.1,2 Rarely, patients may present with massive hemothorax under tension from acute hemorrhage secondary to rupture of the AVM. ...

Haemothorax, haemopneumothorax, and pneumothorax were the most common complications in 85 patients with penetrating stab injuries of the chest. These complications were amenable to conservative treatment by aspiration or drainage of the pleural space. Immediate operation was indicated in 30 cases. Indications for surgery were haemorrhage from a major systemic or pulmonary vessel or the heart, cardiac tamponade, diaphragmatic penetration, oesophageal and bronchial tears, and sucking chest wounds. The need for immediate operation was clinically obvious at presentation in most cases. It should have been suspected from the situation of the entry wound, the nature of the weapon used, the size of the haemothorax, and the clinical findings in the others. All 11 deaths occurred in that group in which early operation was indicated, and some could have been averted had the need for operation been suspected early. Seven patients developed an empyema; five were in the group that required immediate surgery ...

Microscopically, irregularly branched blood vessels extending into the gray matter from the meningeal surface are surrounded by a concentric arrangement of proliferating spindle-formed cells. Ultrastructurally these proliferating cells are composed of elongated heterochromatin-rich nuclei and slender cytoplasm-containing microfilaments, occasionally associated with desmosomal junctions and basal laminalike structures. Judging from these findings, together with a negative immune reaction for S-100 protein, the histogenesis of these proliferating cells is most probably meningothelial in origin.. AB - A case ...
Chest injuries are directly responsible for more than 25% of all motor vehicle fatalities that occur annually in this country. Injuries to the chest are classified as BLUNT (motor vehicle accidents) or PENETRATING (gunshot wounds or stab wounds).. Severity of PENETRATING chest injuries is based on the proximity to major blood vessels, the heart, or lungs. Many stab wounds to the chest puncture the lung, resulting in pneumothorax. In many of these cases, blood vessels can be lacerated, causing a hemothorax, or shock (low blood pressure). All potential chest penetrations must be evaluated IMMEDIATELY by a qualified Emergency Physician to exclude the possibility of a more serious injury.. BLUNT chest injuries account for the majority of chest injuries sustained in motor vehicle accidents or falls. Blunt force to the chest wall can result in a rib fracture, lung contusion, or myocardial contusion.. Many of these problems will require hospitalization for treatment.. Hope this article will provide you ...
