1/245. Spontaneously developed aneurysm of the ductus arteriosus in an adult.We report an unusual adult case of aneurysm associated with the ductus arteriosus. A 67-year-old female, who suffered recurrent nerve palsy, was diagnosed as having an aneurysm of the ductus arteriosus. The aneurysm, located in the medial aspect of the aortic ischimus and projected toward the pulmonary artery, was successfully repaired using a Dacron patch. A pathologic review of the aneurysm revealed the degeneration of the aortic media.- - - - - - - - - - ranking = 1keywords = duct (Clic here for more details about this article) |
2/245. Regression of ductus arteriosus aneurysm in a neonate demonstrated by three-dimensional computed tomography.We present a case of ductus arteriosus aneurysm in a neonate in whom the diagnosis was made by echocardiography, three-dimensional surface rendering computed tomography (CT) and was subsequently confirmed by angiography. Regression of aneurysm after indomethacin treatment was clearly demonstrated in a follow-up CT scan. To our knowledge, this is the first report of ductus arteriosus aneurysm and its regression detected by 3D surface rendering CT.- - - - - - - - - - ranking = 1keywords = duct (Clic here for more details about this article) |
3/245. Direct cervical internal carotid access for GDC treatment of an ophthalmic origin carotid aneurysm.The use of detachable coils in the treatment of intracranial aneurysms continues to evolve since its introduction in 1991 [1-5]. Although not well described in the literature, technical considerations in gaining and maintaining access to intracranial aneurysms play a pivotal role in any successful endovascular treatment. Tortuosity and looping of the cervical internal carotid artery (ICA) is one problem occasionally encountered. These unusual loops, in addition to the normal turns of the carotid siphon result in less control of the microcatheter tip. This problem culminated in this case where an ophthalmic origin carotid aneurysm could not be successfully treated from the standard femoral approach due to the presence of multiple ICA turns, with the presence of a proximal cervical ICA turn being particularly bothersome. This problem was circumvented by use of direct surgical access to the cervical ICA above the cervical ICA turn, allowing for successful endovascular aneurysm treatment with detachable coils.- - - - - - - - - - ranking = 0.16666666666667keywords = duct (Clic here for more details about this article) |
4/245. aneurysm of the pulmonary trunk with patent arterial duct.We present a 14-year-old female with a massive aneurysm of the pulmonary trunk occurring secondary to bacterial endocarditis of the patent arterial duct. Echo Doppler imaging, magnetic resonance and angiography confirmed the diagnosis. On intermediate follow-up after surgical correction, the echo studies and cardiac catheterization disclosed no residual lesions. The patient is now asymptomatic.- - - - - - - - - - ranking = 0.83333333333333keywords = duct (Clic here for more details about this article) |
5/245. An aneurysm of the petrous internal carotid artery.Internal carotid artery aneurysms are a rare cause of pulsatile tinnitus and conductive hearing loss but should be borne in mind when there is a suspected diagnosis of glomus jugulare or high-riding jugular bulb. Most cases are congenital. We present a case of otorrhagia which was initially thought to be a glomus jugulare, the diagnosis of internal carotid artery aneurysm was made at angiography and treated by balloon embolization.- - - - - - - - - - ranking = 0.16666666666667keywords = duct (Clic here for more details about this article) |
6/245. An aneurysm involving the axillary artery and its branch vessels in a major league baseball pitcher. A case report and review of the literature.baseball pitchers appear to be prone to aneurysms of the axillary artery and its branches. The cause is probably related to repetitive compression of or tension on the vessels at the level of the pectoralis minor muscle and the humeral head, which is exacerbated by the pitching motion. The incidence of aneurysms of the axillary artery and its branches among pitchers and other athletes is not known, nor is it clear whether pitchers who are at high risk of vascular injury can be identified before irreversible damage to the vessels has occurred. Perhaps patients who have documented compression or occlusion of the vessel with the arm in the abducted, externally rotated position are at higher risk. Screening pitchers to identify those with axillary artery compression, aneurysm, or thrombosis has also not been shown to be effective. Certainly, many pitchers will have some level of compression of the axillary artery with their arm in the pitching position but will never develop any clinical abnormality requiring treatment. Screening would therefore probably lead to a high false-positive rate. It is clear, however, that pitchers who complain of ischemia-type symptoms such as early fatigue or who have evidence of emboli require a complete evaluation to rule out any abnormality of the axillary artery or one of its branches. Orthopaedic surgeons who see pitchers and other athletes involved in repetitive overhead motions need to be aware of this disorder so that they order the appropriate tests and obtain a vascular consultation--and make a prompt diagnosis. Treatment will vary depending on the type of lesion and on which vessel or vessels are involved, and should be decided on by the team of surgeons treating the patient.- - - - - - - - - - ranking = 0.16666666666667keywords = duct (Clic here for more details about this article) |
7/245. pulmonary artery aneurysm.Main pulmonary artery aneurysm is an exceedingly rare entity. We present a case of main pulmonary artery aneurysm with patent ductus arteriosus in a sixty-year-old woman. The aneurysm was successfully treated with aneurysmectomy and primary anastomosis of the defect of the main pulmonary artery, and the patent ductus arteriosus was divided. The etiology, operative indication and surgical intervention of main pulmonary artery aneurysm are discussed along with a review of the literature.- - - - - - - - - - ranking = 0.33333333333333keywords = duct (Clic here for more details about this article) |
8/245. Hughes-Stovin syndrome: a case report and review of the literature.A young man presented with prolonged pyrexia, recurrent optic neuritis, thrombophlebitis and bilateral pulmonary artery aneurysms with thrombus formation. The life-threatening hemoptysis necessitated mechanical ventilatory support and emergency left lower lobectomy. Systemic corticosteroids conferred clinical improvement and reduction of the remaining right pulmonary artery aneurysm. The patient eventually succumbed to sudden massive hemoptysis. This report underscores the unpredictable nature of this syndrome and emphasises the need for aggressive surgical intervention of pulmonary artery aneurysms in Hughes-Stovin syndrome.- - - - - - - - - - ranking = 0.16666666666667keywords = duct (Clic here for more details about this article) |
9/245. Anterior tibial aneurysm following inversion injury to the ankle.Arterial injuries in nonpenetrating low-energy injuries to the extremities are rare but can occur when joint injuries put the vessels in traction against their immobile attachments to the long bones. The most common injuries are to the popliteal artery (because of its tethered nature proximal to the popliteal fossa) and the brachial artery (because it is tethered to the humerus proximal to the elbow). The second reported case of an aneurysm of the anterior tibial artery resulting from an inversion injury to the ankle is described.- - - - - - - - - - ranking = 0.054922771991847keywords = bile (Clic here for more details about this article) |
10/245. Functional, life-threatening disorders and splenectomy following liver transplantation.splenectomy (SPL) in cirrhotic patients undergoing liver transplantation (LTx) may resolve specific problems related to the procedure itself, in case of functional and life-threatening clinical situations often occurring as a result of liver cirrhosis and portal hypertension. METHOD: A single-center experience of ten splenectomies in a series of 180 consecutive adult liver transplant patients over a period of 6 yr is reported. The mean patient age was 46.8 /- 9.5 yr (range 25 57 yr). Indications for SPL were post-operative massive ascitic fluid loss (n = 3), severe thrombocytopenia (n = 3), acute intra-abdominal hemorrhage (n = 2), infarction of the spleen (n = 1), and multiple splenic artery aneurysms (n = 1). RESULTS: Extreme ascites production due to functional graft congestion disappeared post-SPL, with an improvement of the hepatic and renal functions. SPL was also effective in cases of thrombocytopenia persistence post-LTx, leading to an increase in the platelet count after about 1 wk. Bleeding episodes related to left-sided portal hypertension or trauma were also resolved. The rejection rate during hospitalization was 0%, and no other episodes were recorded in the course of the long-term follow-up. However, sepsis with a fatal outcome occurred in 4 patients, i.e. between 2 and 3 wk post-SPL in three cases and 1 yr after the procedure as a result of pneumococcal infection in the last case. Fatal traumatic cranial injury occurred 3 yr post-LTx in another case. Five patients (50%) are still alive and asymptomatic after a median follow-up period of 36 months. CONCLUSION: The lowering of the portal flow appears to resolve unexplained post-operative ascitic fluid loss as a result of functional graft congestion following LTx. However, because of the enhanced risk of SPL-related sepsis, a partial splenic embolization (PSE) or a spleno-renal shunt could be used as an alternative procedure because it allows us to preserve the immunological function of the spleen. SPL is indicated in case of post-transplant bleeding due to left-sided portal hypertension and trauma, spleen infarction, and to enable prevention of hemorrhage in liver transplant patients with multiple splenic artery aneurysms. Severe and persistent thrombocytopenia could be treated with PSE. Because the occurrence of fatal sepsis post-SPL is a major complication in LTx, functional disorders, such as ascites and thrombocytopenia, should be treated with a more conservative approach.- - - - - - - - - - ranking = 0.16666666666667keywords = duct (Clic here for more details about this article) |
