1/23. Pericardial tamponade: an unusual complication of lobectomy for lung cancer.A rare case of pericardial tamponade developed in a 69-year-old man after a right upper lobectomy for lung cancer. This unusual complication presented in the early postoperative period and was associated with what we believed to be an aberrant right bronchial artery coming off the intrapericardial portion of the aorta. This vessel retracted into the pericardial sac where it bled causing a pericardial tamponade.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/23. cardiac tamponade originating from primary gastric signet ring cell carcinoma.A 45-year-old man with dry cough and dyspnea was referred by a medical practitioner for evaluation of heart failure on February 10, 1996. Chest X-ray revealed increased cardiothoracic ratio, and ultrasonographic echocardiography disclosed massive pericardial effusion with right ventricular collapse. cardiac tamponade was diagnosed and pericardiocentesis was performed. Ten days after admission, the pleural effusion had become more pronounced, and thoracocentesis was performed. carcinoembryonic antigen level was elevated in both the pericardial and pleural effusion, and cytology implicated adenocarcinoma, which suggested malignant effusion. Endoscopic study disclosed gastric cancer in the posterior wall of the upper body, and the histopathological diagnosis was signet-ring cell carcinoma. The patient died of respiratory failure on May 2, 1996, and autopsy was performed. The final diagnosis was gastric cancer with pulmonary lymphangitis, pericarditis, and pleuritis carcinomatosa, accompanied by enlargement of mediastinal and paraaortic lymph nodes. Interestingly, the primary signet-ring cell carcinoma of the stomach was situated mostly in the mucosa. Deep in the submucosal region, there was prominent invasion of the intralymphatic vessels, without direct destruction of the mucosa muscularis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/23. Fatal pericardial tamponade after Wallstent implantation for malignant superior vena cava syndrome.PURPOSE: To report a rare, fatal complication of superior vena cava Wallstent implantation. CASE REPORT: A 59-year-old man presenting with superior vena cava syndrome caused by small-cell lung cancer underwent stent implantation of 2 kissing Wallstents >1.5 cm above the right atrium. Despite correct stent deployment, vessel perforation occurred in a section not encased by tumor, which led to fatal pericardial tamponade shortly after the procedure. autopsy revealed perforation of a stent strut through the caval wall into the pericardial space. Anatomical and methodological reasons are discussed. CONCLUSIONS: The interventionist should be aware of this rare complication. Alternative stent designs avoiding the sharp ends of Wallstents and Palmaz stents should be considered.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/23. Medicolegal diagnostic value and clinical significance of traumatic incomplete tears of the basilar artery.Ruptures of arteries of the vertebrobasilary system are relatively frequent in medicolegal practice, and their origin may be both natural and violent. tears that affects the whole thickness of the basilar artery cause subarachnoid hemorrhage (SAH), with an often rapid fatal outcome. 1-3 However, in some situations, arterial tears may be incomplete, involving the intima or both the intima and the media, but with preserved adventitia. 1, 4 Although such incomplete tears are not the source of immediate subarachnoid bleeding, their presence may be important from both a medicolegal and a clinical point of view.The aim of this article is to point out the significance of incomplete tears of basilar artery as a possible diagnostic sign of traumatic origin of SAH as well as a certain mechanism of injury, which involves forcible hyperextension and rotational movements of the head. The authors also describe their method of performing longitudinal section of the basilar artery, both at autopsy and for histologic examination, which is convenient for identifying multiple transversal incomplete tears of this blood vessel. The article is based on the analysis of three cases from the autopsy material of the Institute of forensic medicine in Belgrade.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/23. Lymphatic cardiac tamponade after open-heart surgery with liver dysfunction.A 46-year-old female with alcoholic liver dysfunction was admitted for mitral regurgitation due to infective endocarditis. She underwent mitral valvuloplasty and resection of the vegetation without complication. After removal of the chest tube, late cardiac tamponade occurred and subsequently recurred. On the 64th day after mitral valvuloplasty, we performed redo median sternotomy with small laparotomy trying to reveal and repair injured lymphatic vessels in the pericardial space and successfully cured the leakage of lymph. The post reoperative course was uneventful and the patient was discharged 20 days after reoperation. We review a rare complication of recurrent cardiac tamponade of lymphatic leakage associated with liver dysfunction.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/23. Prolonged right ventricular failure after relief of cardiac tamponade.PURPOSE: To report a case of severe and fatal cardiac complication following pericardiotomy to relieve a malignant tamponade. Right ventricular (RV) failure was responsible for major hypoxemia and for a persistent shunt through a patent foramen ovale. In the absence of pulmonary embolism and coronary occlusion, possible pathophysiologic mechanisms are discussed. CLINICAL FEATURES: This 53-yr-old patient presented with oropharyngeal carcinoma previously treated by chemotherapy. One month later, he showed clinical and echocardiographic signs of cardiac tamponade. He had a circumferential pericardial effusion with complete end-diastolic collapse of the right cavities. After an emergent pericardiotomy, he rapidly presented severe hypoxemia. Transesophageal echocardiography showed an akinetic and dilated right ventricle, paradoxical septal wall motion and a normal left ventricular function. A contrast study revealed a right-to-left shunt. No residual pericardial effusion was detectable. Pulmonary angiography excluded a pulmonary embolism and the coronary angiogram was normal. troponin Ic was elevated postoperatively and peaked on day two (3.78 micro g x L(-1)). The patient died of refractory shock with persistent intracardiac shunt and RV akinesia on day nine. CONCLUSION: Although pulmonary embolism or thrombus of a coronary vessel are the most common causes of prolonged RV failure after pericardiotomy, other mechanisms may be invoked. The possibility is raised that a rapid increase in RV tension may induce the development of muscular injury and impair coronary blood flow, despite a normal coronary angiogram. These could result in a stunned myocardium and opening of a patent foramen ovale. We hypothesize that gradual decompression of a chronic pericardial effusion might be beneficial in patients at risk.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/23. Fatal pulmonary arterial dissection and sudden death as initial manifestation of primary pulmonary hypertension: a case report.We report a rare case of sudden death due to cardiac tamponade following intrapericardial rupture of a main pulmonary artery dissecting aneurysm. On pathology examination, the pulmonary artery showed an intimal tear in an arterial wall area with reduced thickness. However, no degenerative, inflammatory or necrotic processes were evident within the vessel wall. hypertrophy of the wall of vasa vasorum in the adventitia of the pulmonary artery was found, as well as bilaterally diffuse myointimal arterial hyperplasia of the lung vasculature. According to these findings, we conclude that pulmonary artery rupture occurred in a patient with chronic unrecognized primary pulmonary hypertension.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/23. Successful surgical treatment of rupture of coronary arteriovenous fistula with unconsciousness after chest and back pain.A 65 year-old woman was admitted to our hospital, because of unconsciousness after chest and back pain. echocardiography showed pericardial effusion. She suffered from pre-shock due to cardiac tamponade. Although a cause of cardiac tamponade was unclear, we performed emergency surgical treatment without coronary angiography. In operation, we found a rupture of coronary arteriovenous fistula and repaired it. The patient recovered from the surgery uneventfully. Coronary artery fistula is an abnormal communication between a coronary artery and a cardiac chamber or major vessel. It is the most common congenital anomalies of the coronary arteries. Many patients with these anomalies remain asymptomatic, but some patients develop symptoms of congestive heart failure, infective endocarditis, myocardial ischemia, arrhythmia, or rupture of an aneurismal fistula. Usually, the dilatation of fistula is common, and although 19% of this may become aneurysmal, the rupture of the aneurysm is very rare. We report a case of ruptured coronary arteriovenous fistula who underwent successful emergent surgery.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/23. Right atrial mass presenting as cardiac tamponade.Intracavitary tumors such as angiosarcomas are prone to embolize, and occlude valves and vessels. Intramyocardial tumors cause cardiac failure and arrhythmias. Pericardial tumors cause effusions which result in tamponade. It is very rare that an intracavitary tumor presents itself with a cardiac tamponade. A 32-year old woman presented to the emergency room with palpitation and shortness of breath. Her physical examination revealed pulsus paradoxus and jugular venous distention. The transthoracic echocardiography showed normal left ventricular function, and an intracavitary right atrial mass. As the patients clinical status deteriorated an emergency operation was performed. The hemorrhagic pericardial fluid was cytologically positive for malignant cells. Histopathological findings were indicative of an angiosarcoma.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/23. cardiac tamponade following coronary arterial rupture during coronary angioplasty.We describe a patient in whom percutaneous transluminal coronary angioplasty (PTCA) was complicated by rupture of the left anterior descending coronary artery (LAD) with pericardial tamponade. The outcome was favorable with drastic intervention which included: occlusion of the bleeding vessel with the PTCA balloon, pericardiocentesis, and ligation of the vessel without the need of aortocoronary bypass graft.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
