1/194. Pseudoaneurysm of the superficial femoral artery following accidental trauma: result of treatment by percutaneous stent-graft placement.Accidental trauma frequently involves the extremities, and can extend to involve their blood supply, causing exsanguinating hemorrhage and pseudoaneurysm in the involved blood vessel. This is traditionally managed by surgical repair. We report a case in which control of life-threatening hemorrhage and exclusion of a large, post-traumatic pseudoaneurysm in the superficial femoral artery was performed by a commercially available stent-graft, without complication. This treatment method may be a safe and effective alternative to surgery in selected patients.- - - - - - - - - - ranking = 1keywords = blood vessel, vessel (Clic here for more details about this article) |
2/194. Access to the traumatized vertebral artery: an unusual approach.Although injuries to the vertebral arteries are relatively uncommon, there are several different methods used to gain access to these vessels, and to control any bleeding arising from them. We describe a case of torrential oropharyngeal bleeding following a stab wound to the neck in which rapid access to the vertebral artery was gained using a paramedian mandibulotomy; this approach has not previously been documented. The other approaches are discussed.- - - - - - - - - - ranking = 0.40403083743002keywords = vessel (Clic here for more details about this article) |
3/194. Diffuse alveolar hemorrhage and pulmonary capillaritis due to propylthiouracil.propylthiouracil (PTU) has recently been observed to be associated with antineutrophil cytoplasmic antibody (ANCA)-positive small vessel vasculitis, resulting in crescentic glomerulonephritis and, infrequently, diffuse alveolar hemorrhage (DAH). We describe a case of a 23-year-old pregnant woman who developed a perinuclear ANCA and antimyeloperoxidase-positive small vessel vasculitis manifesting as DAH and crescentic glomerulonephritis after she began taking PTU. An open lung biopsy was consistent with pulmonary capillaritis. She responded to corticosteroid therapy and discontinuation of PTU. DAH can be caused by pulmonary capillaritis, bland hemorrhage, or diffuse alveolar damage. To our knowledge, this represents the first documentation of an underlying pulmonary capillaritis in a case of PTU-induced DAH.- - - - - - - - - - ranking = 0.80806167486005keywords = vessel (Clic here for more details about this article) |
4/194. Massive intraperitoneal bleeding from tryptic erosions of the splenic vein. Another cause of sudden deterioration during recovery from acute pancreatitis.Acute bleeding is a rare, but frequently fatal complication of pancreatitis. Bleeding into the gastrointestinal tract may occur owing to gastric or duodenal erosions, peptic ulcers, or varices in the esophagus, stomach, or colon following splenic vein thrombosis, or intraperitoneally from eroded vessels in pancreatic pseudocysts or expanding pseudoaneurysms. We report a novel case of massive intraperitoneal bleeding owing to tryptic erosions of the splenic vein in a patient recovering from acute pancreatitis. diagnosis of the bleeding was made by ultrasound and ultrasound-guided blood aspiration. The source of the bleeding was identified intraoperatively, and a left-sided pancreatectomy and a splenectomy were performed.- - - - - - - - - - ranking = 0.40403083743002keywords = vessel (Clic here for more details about this article) |
5/194. Tracheocarotid artery fistula infected with methicillin-resistant staphylococcus aureus.Massive life-threatening haemorrhage from a fistula between the trachea and a major blood vessel of the neck is a rare complication of the tracheostomy procedure, well-recognized by anaesthetists and otolaryngologists. Although the lesion is likely to be encountered at autopsy, it is not described in histopathological literature. The possible causes are discussed together with the macroscopic and microscopic appearances of the lesion. Suitable procedures for its identification and for obtaining appropriate histopathological blocks are suggested. Presence of methicillin-resistant staphylococcus aureus (MRSA) has not been documented before and might have contributed to the genesis of the fistula in this case.- - - - - - - - - - ranking = 1keywords = blood vessel, vessel (Clic here for more details about this article) |
6/194. Vascular adrenal pseudocyst: cytologic and immunohistochemical study.Adrenal vascular cysts are rare lesions that might be considered in the differential diagnosis of adrenal tumors. Their origin is not clear. We report the clinicopathological findings of a large adrenal hemorrhagic pseudocyst (AHP) in a 73-yr-old man who complained of abdominal pain. An abdominal CT showed a 9 cm tumor in the left adrenal. A fine-needle aspiration biopsy (FNAB) was hemorrhagic and inconclusive. The tumor was excised and touch imprints were taken showing groups of spindled and fusiform cells with elongated nuclei, without atypia. Histologically, the tumor was well delimited by a fibrous capsule and contained numerous cystic spaces lined by endothelial cells and filled with erythrocytes, fibrin thrombus, and necrotic debris. Immunohistochemical study showed strong positivity for factor viii-RA, CD31, and CD34. Also, the remaining adrenal showed a prominent frame of thin and medium caliber vessels, supporting a vascular origin for this entity. This case illustrates the difficulty in making a diagnosis by FNA and to keep in mind AHP when hematic aspirates are obtained from an adrenal tumor mass.- - - - - - - - - - ranking = 0.40403083743002keywords = vessel (Clic here for more details about this article) |
7/194. Rare complication of massive hemorrhage in neurofibromatosis with arteriovenous malformation.Neurofibromatosis is rare in the general population. Its clinical manifestations are systemic and variable. The clinical presentation of cutaneous lesions is even more variable. Some patients have giant tumors in the trunk or limbs (so-called "elephant neurofibromatosis"). The pathological findings are diffuse neurofibromatosis of the nerve trunk associated with overgrowth of subcutaneous tissue and skin. The associated vascular malformations make most surgeons hesitant to address them because bleeding to death is possible if the bleeding is not well controlled. According to the authors' experience in treating this complication of neurofibromatosis, they noted that there are three key points to reducing the amount of hemorrhage to a minimal level: (1) hypotensive anesthesia, (2) preliminary sutures around the lesion, (3) ligation of the limited numbers of feeding vessels in the vascular malformation of the neurofibroma. Ligating these pedicles can decrease bleeding during resection of the neurofibroma, as demonstrated in their patient.- - - - - - - - - - ranking = 0.40403083743002keywords = vessel (Clic here for more details about this article) |
8/194. trachea--innominate artery fistula following tracheostomy. Successful repair using an innominate vein graft.This report discusses the first recorded patient in whom a trachea--innominate artery fistula after tracheostomy was treated successfully by resection of the eroded segment of artery followed by graft replacement using the patient's left innominate vein. The mechanism of vessel erosion and its prevention are discussed. Also, suitable methods are presented for obtaining temporary control of the severe hemorrhage associated with a tracheoarterial fistula while simultaneously maintaining an adequate airway.- - - - - - - - - - ranking = 0.40403083743002keywords = vessel (Clic here for more details about this article) |
9/194. Sudden bilateral deafness from hyperleukocytosis in chronic myeloid leukemia.Sudden-onset bilateral deafness as a clinical manifestation of hyperleukocytosis in chronic myeloid leukemia (CML) is a rare occurrence. We found only 27 clinical descriptions in 16 published papers. In this work, the authors present a review on deafness in CML and describe a new case with prominent hyperleukocytosis, where the neurological findings suggest slowing of the circulation through small blood vessels in the brainstem as the cause of deafness. The evolution was good after treatment. To our knowledge, this is the second case documented with electrical auditory brainstem-evoked potentials and the first with magnetic resonance imaging.- - - - - - - - - - ranking = 1keywords = blood vessel, vessel (Clic here for more details about this article) |
10/194. Control of major hemorrhage from the spleno-mesenteric vein junction during pancreaticoduodenectomy: successful use of an occlusion balloon catheter.BACKGROUND/AIMS: Vascular disruption is sometimes associated with intractable hemorrhage due to either vessel fragility or increased blood flow rates in patients with chronic pancreatitis during surgical operation. This paper describes the successful use of an occlusion catheter for repairing a major laceration at the spleno-mesenteric vein junction. methods: A 14-Fr Fogarty occlusion balloon catheter was directly inserted into the splenic vein through the site of venous laceration and inflated to stop blood flow from the splenic vein. RESULTS: This procedure perfectly controlled massive hemorrhage from the spleno-mesenteric vein junction. The injured site was repaired with a continuous suture in 5 min. CONCLUSION: The direct insertion of a balloon catheter to the injured site is simple and expeditious to control major hemorrhage from the spleno-mesenteric vein junction when the situation is otherwise unmanageable.- - - - - - - - - - ranking = 0.40403083743002keywords = vessel (Clic here for more details about this article) |
