1/14. Active contrast extravasation in spontaneous rupture of hepatocellular carcinoma: a rare CT finding.Spontaneous rupture of hepatocellular carcinomas are uncommon but constitute a critical and life threatening condition. diagnosis is important so that either surgery or emergency arterial embolisation can be considered for hepatic haemostasis. We describe active extravasation of intravenous contrast medium on CT in a patient who presented with intraperitoneal haemorrhage secondary to spontaneous rupture of hepatocellular carcinoma.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
2/14. Subdural block complicating spinal anesthesia?IMPLICATIONS:Features suggestive of subdural block appeared after an apparently normal subarachnoid block. The long bevel of the reusable Quincke-type spinal needle may have contributed to the development of this complication. We propose that spinal needles should have a smaller bevel to minimize the possibility of such a complication.- - - - - - - - - - ranking = 7.7396768919545keywords = subdural (Clic here for more details about this article) |
3/14. rupture of an internal carotid artery aneurysm during angiography with leakage of contrast medium via an external ventricular drain.With a ruptured intracranial aneurysm producing subarachnoid haemorrhage (SAH) cerebral angiography is currently used for identification of the affected vessel. Aneurysm rerupturing is one of the more serious complications of cerebral angiography and has been frequently described. We report a 61-year-old man who presented with SAH who had rerupture of a large aneurysm of the internal carotid artery during angiography. A substantial amount of contrast medium escaped via a ventricular drain. The three main risk factors for rerupture of an aneurysm are: angiography performed within 6 h of the primary SAH, an aneurysm on the internal carotid artery and an unfavourable Glasgow coma score.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
4/14. Extravasation of contrast medium into the subdural space during cavernous sinus venography: a rare complication.We recently observed subdural extravasation of contrast medium during transfemoral catheter venography of the cavernous sinus, performed to elucidate the relationship between a parasellar mass and the sinus. The precise mechanism is unknown but a dural tear during manipulation of the guide wire or catheter was thought to be the most likely cause.- - - - - - - - - - ranking = 38.698384459772keywords = subdural (Clic here for more details about this article) |
5/14. Efficacy of endovascular surgery for the treatment of acute epidural hematomas.BACKGROUND AND PURPOSE: Recent advances in the equipment and technology for endovascular surgery have led to an increasing number of patients undergoing this procedure to treat various lesions. The purpose of this study was to investigate the efficacy of early-stage endovascular surgery to treat growing acute epidural hematomas (AEDHs). methods: Over a period of 2.5 years, endovascular intervention was performed in nine patients with AEDHs, as shown by the extravasation of contrast medium and the recognition of growing hematomas on CT scans. Embolization was performed by using catheters superselectively advanced with a microguidewire until it reached the area just before the bleeding point. RESULTS: In all nine cases, bleeding from the middle meningeal artery ceased immediately after treatment, and further surgical intervention was avoided. In three of five patients with additional lesions, surgical intervention was also conducted to treat an acute subdural hematoma (two patients) or a contusion hematoma (one patient); in two cases, these lesions were located on the contralateral side. CONCLUSION: In patients with thin AEDHs in the early stage, angiography followed by endovascular intervention allows for conservative treatment. Notable clinical benefits can be achieved in patients with complicated, multiple lesions.- - - - - - - - - - ranking = 7.7396768919545keywords = subdural (Clic here for more details about this article) |
6/14. Acute haemorrhage in patients with advanced head and neck cancer: value of endovascular therapy as palliative treatment option.AIMS: Acute or subacute haemorrhage is one of the most frightening complications in patients suffering from advanced head and neck cancer. Few articles report experience with superselective endovascular therapy for this purpose. Is endovascular therapy underestimated in the field of palliative head and neck cancer therapy? This study set out to investigate this question. patients AND methods: A review was undertaken of the clinical courses of seven patients (six men, one woman) suffering from incurable, advanced head and neck cancer (four pharyngeal, two laryngeal, one neck) and treated with superselective endovascular strategies as an emergency procedure for acute bleeding. RESULTS: All patients were successfully treated without evidence of neurological complication. patients reached a median survival of 20 weeks (range eight-168 weeks). Following endovascular treatment all patients were discharged from the hospital within several days. Three patients survived almost free of symptoms for several weeks and were able to stay at home with their families until their death. CONCLUSION: We conclude that in the field of palliative care, superselective endovascular therapy deserves to be considered alongside standard treatment options for the management of acute haemorrhage from advanced head and neck cancer.- - - - - - - - - - ranking = 6keywords = haemorrhage (Clic here for more details about this article) |
7/14. Retropharyngeal haemorrhage from a vertebral artery branch treated with distal flow arrest and particle embolisation.Retropharyngeal haematoma is a rare cause of rapid neck swelling that may result in fatal upper respiratory airway obstruction. Reported causes include trauma, surgery, retropharyngeal inflammation, carotid aneurysm, aberrant artery at the thoracic inlet and bleeding diathesis. We report a 90-year-old man who developed rapid and progressive neck swelling following a minor traumatic episode. Computed tomography showed a large low-density retropharyngeal haematoma extending from the skull base to the mediastinum, with suspected extravasation. The right vertebral artery angiogram confirmed contrast agent extravasation arising from a small branch artery. This was treated with temporary distal flow arrest and particle embolisation.- - - - - - - - - - ranking = 8.8828608507819keywords = haematoma, haemorrhage (Clic here for more details about this article) |
8/14. Subdural collection of intravenous fat emulsion in a neonate. Complication of central venous catheterization for total parenteral nutrition.An infected subdural collection of intravenous fat emulsion (Intralipid) was diagnosed in a 5-week-old premature infant who was receiving total parental nutrition (TPN) through a facial vein cutdown. This fluid was successfully drained and the infection, due to staphylococcus epidermidis, was treated with vancomycin. We postulate that the subdural collection occurred as a result of septic thrombosis of the internal jugular vein with subsequent retrograde flow and infiltration of Intralipid from the bridging veins into the subdural space. This complication of central TPN has not been reported previously.- - - - - - - - - - ranking = 23.219030675863keywords = subdural (Clic here for more details about this article) |
9/14. rupture of intracranial aneurysms and ventricular opacification during carotid angiography.Two cases of rupture of intracranial aneurysms and opacification of the lateral ventricles occurring during carotid angiography are reported and x-rays of the haemorrhage from the aneurysms are presented. Though the possibility of this complications remains a real one, the early use of this valuable procedure should not be precluded.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
10/14. rupture of an intracranial aneurysm of the carotid artery with ventricular visualization during angiography.rupture of an aneurysm during angiography, with extravasation of blood and contrast medium into the ventricular system occurs rarely. We wish to add one personal observation to those few cases already published. Haemorrhage from an aneurysm of the internal carotid artery recurred during angiography in a 52-year-old comatose man. Through extravasation of blood and contrast medium into the ventricles these became fully visible on the X-ray screen. The question of a direct causal relationship between angiography and rupture of an aneurysm, the frequency and risk of this coincidence and mortality are discussed. Since computerised tomography now precedes angiography in cases of subarachnoid haemorrhage, complications arising from angiography could be reduced by proper timing.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
