1/47. The acute diagnosis of Takayasu's arteritis based on helical CT angiography of the chest and neck in the emergency room.Recently, a young woman presented acutely with a left hemispheric stroke and differing blood pressures in the arms as her initial manifestation of Takayasu's arteritis. Helical CT angiography, performed to rule out aortic dissection, revealed a thickened wall of the aortic arch with stenoses and occlusions of the great vessels, suggesting the diagnosis. The sequence of imaging studies and findings in this unusually catastrophic presentation of a typically insidious disease are highlighted.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/47. Successful cricothyrotomy after thrombolytic therapy for acute myocardial infarction: a report of two cases.Cricothyrotomy is an emergency airway procedure that is generally performed after failure of primary methods for securing the airway. Coagulopathy has traditionally been considered a relative contraindication to cricothyrotomy, but there is little evidence in the literature to support this. There have been no reports of successful cricothyrotomy in a patient who had received systemic thrombolytic therapy. This report, from the National Emergency Airway Registry, is the first to describe successful cricothyrotomy in this context. We describe 2 patients who received thrombolytic therapy and then had cricothyrotomy performed after failure of other airway measures. The first patient was a 67-year-old man who developed severe pulmonary edema and respiratory failure less than 30 minutes after administration of tissue plasminogen activator using an accelerated regimen. Both intubation and attempts at ventilation using an esophageal/tracheal double-lumen airway (Combitube, Kendall-Sheridan, Argyle, NY) were unsuccessful, and the emergency physician then performed an uneventful cricothyrotomy using a vertical midline incision. There were no complications, and bleeding was minimal. The second patient was a 45-year-old man who developed severe angioedema with respiratory compromise after receiving streptokinase for acute myocardial infarction. intubation was impossible, and a cricothyrotomy was performed. Significant bleeding was controlled initially with packing and was semielectively explored later in the ICU with ligation of several small bleeding vessels. Prior administration of thrombolytic therapy does not preclude successful cricothyrotomy.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/47. Urgency of operation in infracardiac total anomalous pulmonary venous connection.BACKGROUND: Because the tendency for pulmonary venous obstruction in the infracardiac type of total anomalous pulmonary venous connection may be partially dependent on the connection of the descending vein to the portal vein, the inferior vena cava, or one of their tributary vessels, we reviewed our surgical experience with various subtypes of infracardiac total anomalous pulmonary venous connection. methods: The urgency of operation in 4 neonates with infracardiac total anomalous pulmonary venous connection was reviewed. RESULTS: Two patients with pulmonary venous obstruction in whom the descending vein connected to the portal vein were operated on immediately with successful outcome. One patient who had become critically ill after the ductus venosus had closed died before operation could be undertaken. One patient in whom the descending vein connected to the left hepatic vein was operated on electively with successful outcome. CONCLUSIONS: In hemodynamically stable patients with no clinical or echocardiographic signs of pulmonary venous obstruction, some form of differentiation with regard to urgency of operation may be appropriate. When the descending vein connects to the inferior vena cava or a hepatic vein, the operation may be performed on a semi-elective basis. In contrast, when the descending vein connects to the portal vein or the ductus venosus, operation should generally not be delayed because of the high likelihood of obstruction.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/47. Gastric amyloidosis with massive bleeding requiring emergency surgery.We report a 66-year-old woman who had massive bleeding from a gastric ulcer complicating primary systemic amyloidosis, in whom emergency surgery proved lifesaving. physical examination revealed anemia and macroglossia. gastroscopy was performed, and an extensive, irregular, hemorrhagic ulcer was found in the gastric body. biopsy resulted in a diagnosis of amyloidosis. On the 11th hospital day the patient went into shock as a result of a massive hemorrhage. Emergency surgery was performed, but the extent of the submucosal lesion in the stomach could not be identified, and total gastrectomy was unavoidable. Histological examination of the surgical specimen and biopsy tissue collected from other organs revealed amyloid deposition extending from the submucosa to the muscularis propria of the stomach. There was also deposition of large amounts of amyloid around the small blood vessels in the liver and under the mucosa of the small intestine. The amyloid was AA-antibody-negative and resistant to treatment with K2MO4, and a diagnosis of AL-type systemic amyloidosis was made. The patient's general condition recovered after the operation, but on the 103rd hospital day, she experienced sudden onset of arrhythmia and died. patients with amyloidosis in whom gastrointestinal surgery is performed are rare; only 41 cases, including our own, have been reported in the Japanese literature since 1972.- - - - - - - - - - ranking = 3.5473783800978keywords = blood vessel, vessel (Clic here for more details about this article) |
5/47. Emergency management of spontaneous coronary artery dissection.Six cases of spontaneous coronary arteries dissection are reported. In one patient, triple vessel spontaneous coronary artery dissection was identified. Another patient presented spontaneous left main coronary artery dissection. In one case we found the spontaneous dissection of the left anterior descending artery associated with distal aortic arch dissection. These conditions are very rare and may present a surgical dilemma. Causative factors and underlying pathology are clarified. Prompt diagnosis and surgical intervention is safe and effective. Early recognition of left main coronary artery dissection or three-vessel dissection is essential because urgent coronary artery bypass grafting may be life saving.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
6/47. coronary artery disease obscuring giant cell myocarditis--a case report.A case in which the diagnosis of idiopathic giant cell myocarditis was obscured by the presence of severe coronary artery disease is described. A 47-year-old man presented with recurrent inferior myocardial infarction and complete heart block. cardiac catheterization confirmed severe 2-vessel disease and left ventricular dysfunction. Incessant ventricular arrhythmia rapidly ensued, which did not respond to anti-arrhythmic therapy and overdrive pacing despite complete surgical revascularization. He eventually died. autopsy revealed giant cell myocarditis superimposed on coronary artery disease. Acute myocarditis masquerading as myocardial infarction has been well known, but virtually all reported cases had normal coronary arteries. This case illustrated the fact that even in the presence of obvious coronary artery disease the remote possibility of myocarditis should not be entirely disregarded. Although giant cell myocarditis is a rare and frequently fatal disorder, recent studies suggest that combined immunosuppressive therapy may improve the prognosis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/47. Emergency endovascular treatment of traumatic aortic arch rupture with multiple arch vessel involvement.PURPOSE: To report successful endovascular stent-graft placement for emergency treatment of a complex traumatic injury involving the aortic arch and multiple arch vessels. CASE REPORT: An 81-year-old man underwent stent-graft placement for a complex traumatic vascular injury. Computed tomography on admission documented a dissection along the course of the aortic arch, intramural hematoma along the ascending aorta, dissection of the innominate artery, and a right subclavian artery pseudoaneurysm. The dissection of the aortic arch and the pseudoaneurysm of the right subclavian artery were treated immediately, the dissection of the innominate artery 7 days later. The patient did not develop any complications. follow-up studies performed prior to discharge and at 6 and 12 months after the interventions showed successful repair of the complex vascular injuries. CONCLUSIONS: Traumatic injury of the aortic arch with multiple arch vessel involvement can be treated effectively by means of stent-graft placement.- - - - - - - - - - ranking = 6keywords = vessel (Clic here for more details about this article) |
8/47. Colonoscopically placed hemoclips as treatment for massive appendiceal stump bleeding.Massive bleeding from an appendiceal stump is a rare but occasionally seen severe complication. The bleeding may drain into the abdominal cavity, the retroperitoneum, or the digestive tract. gastrointestinal hemorrhage may occur early or even years after appendectomy. The typical management includes ligation of the bleeding vessel or cecal resection done by either emergency laparotomy or laparoscopy. An alternative treatment option would be an angiographic embolization of the bleeding vessel. We report on a 33-year-old woman with severe lower gastrointestinal hemorrhage 1 day after an apparently uncomplicated appendectomy for acute phlegmonous appendicitis with ligation and invagination of the appendiceal stump. Hemoglobin level dropped to 6.3 g/dl and made blood transfusion necessary. The cause of bleeding was a small intramural branch of the appendiceal artery at the appendiceal stump, which was diagnosed by emergency colonoscopy. The hemorrhage could be controlled endoscopically by placing hemoclips on the distinct vessel in combination with a biological tissue adhesive. The patient recovered thereafter without further intervention. Endoscopic clipping for the treatment of appendiceal stump bleeding is a novel, effective, and safe procedure. Thereby, conventional emergency laparotomy or laparoscopy or angiographic embolization can be avoided.- - - - - - - - - - ranking = 3keywords = vessel (Clic here for more details about this article) |
9/47. Embolization of transected vertebral arteries in unstable trauma patients.The aim of this paper is to report our experience with coil embolization for the treatment of vertebral artery transection in unstable trauma patients. The course of four patients admitted to our units between 1998 and 2003 with traumatic injuries of the upper thorax or neck is described. All had unstable hemodynamic parameters at presentation. Emergent arteriogram revealed vertebral artery transection, which was managed by immediate coil embolization proximal to the injury site. Initial technical success was achieved in all four patients, with hemodynamic improvement. No further treatment or surgery to control the vessel injury was needed. There were no immediate or late complications of the procedure and no neurological sequelae. Emergency coil embolization is an effective endovascular technique for use in unstable patients with angiography findings of a transected vertebral artery.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/47. rupture of an isolated true superficial femoral artery aneurysm: case report.True isolated atherosclerotic aneurysm of the superficial femoral artery is a rare pathology. We report a case of ruptured superficial femoral artery aneurysms (SFAA) not associated with aortic, common femoral or popliteal artery aneurysms. An emergency surgical procedure was performed and, after endoaneurysmal branches ligation, a ePTFE graft interposition was performed. The literature review shows a prevalence of rupture as compared with ischemic complications and the need for surgical repair in case of SFAA with diameter twice the normal vessel size. early diagnosis and management are recommended because of the lower morbility and mortality rates associated with elective surgery by comparison with emergency procedures.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
