1/143. 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) |
2/143. spleen localization of light chain deposition disease associated with sea blue histiocytosis, revealed by spontaneous rupture.Splenic involvement by a light chain deposition disease (LCDD) associated with sea-blue histiocytosis occurred in a 55-year-old man presenting with LCDD of the kidney without myeloma. Lambda light chain deposits were demonstrated by immunohistochemistry in vessel walls and along the ring fibres of the red pulp sinuses. Accumulation of sea blue histiocytes in the cords was also present. Stiffness of the walls of the red pulp sinuses resulting from light chain deposits may have induced accumulation and destruction of circulating blood cells. Lipid catabolism with production of ceroids may have resulted in lipidic histiocytosis with a sea blue histiocyte pattern.- - - - - - - - - - ranking = 0.38924350901406keywords = vessel (Clic here for more details about this article) |
3/143. Combination of transileocolic vein obliteration and balloon-occluded retrograde transvenous obliteration is effective for ruptured duodenal varices.Duodenal varices are a rare site of hemorrhage in patients with portal hypertension, but their rupture is a serious and often fatal event. We report a 65-year-old woman who presented with hematemesis and melena. She was admitted to our department because of prolonged shock, despite having received transfusion of a large volume of blood. Upper gastrointestinal endoscopy revealed nodular varices with active bleeding in the second portion of the duodenum. Endoscopic injection sclerotherapy (EIS) was performed using a tissue adhesive agent, alpha-cyanoacrylate monomer, with only temporary benefit. However, anemia continued to progress after the procedure. Therefore, we combined transileocolic vein obliteration (TIO) with balloon-occluded retrograde transvenous obliteration (B-RIO), using 5% ethanolamine oleate with iopamidol to obliterate the varices. Complete hemostasis was achieved without complications. Neither recurrence of varices nor further bleeding has occurred for over 3 years. We conclude that combined TIO and B-RTO, which can obstruct both the feeding and the draining vessels of duodenal varices to retain the sclerosing agent completely in the varices, is a safe and effective hemostatic measure for ruptured duodenal varices, when EIS has failed to accomplish complete hemostasis.- - - - - - - - - - ranking = 0.38924350901406keywords = vessel (Clic here for more details about this article) |
4/143. Ruptured iliac aneurysms.Iliac aneurysms are uncommon as compared with aneurysms of the abdominal aorta. rupture is the most serious complication of aneurysms of both vessels. Considerable attention has been focused on the management of ruptured abdomonal aortic aneurysms, but ruptured iliac aneurysms have received little notice. The problems in the management of ten ruptured iliac aneurysms, seen over the last five years, together with the rarity of other reports of this condition, have stimulated this review.- - - - - - - - - - ranking = 0.38924350901406keywords = vessel (Clic here for more details about this article) |
5/143. Using transcranial Doppler sonography to augment the neurological examination after aneurysmal subarachnoid hemorrhage.Vasospasm is the leading cause of death in patients who survive initial subarachnoid hemorrhage (SAH). Evidence of blood in the subarachnoid space on computed tomography (CT) scan can often predict the occurrence of vasospasm. Clinically, the onset of new or worsening neurological symptoms is the most reliable indicator of vasospasm. Transcranial Doppler (TCD) sonography studies can further aid the neuroscience nurse's assessment for vasospasm by measuring cerebral blood flow velocities. Physiological changes that occur during vasospasm cause the lumen of the blood vessel to decrease, increasing blood flow velocity through the affected area. Although vasospasm can only be definitively diagnosed by cerebral angiogram, TCD sonography provides a noninvasive, low-risk assessment tool that can be done at the beside. By coupling a patient's vital neurological data with blood flow velocity trends, the neuroscience nurse can anticipate the onset or worsening of vasospasm. This advanced nursing assessment allows for collaboration with the medical team to initiate and adjust appropriate therapies to improve patient outcomes.- - - - - - - - - - ranking = 1keywords = blood vessel, vessel (Clic here for more details about this article) |
6/143. hemoperitoneum following rupture of ectopic varix along splenorenal ligament in extrahepatic portal vein obstruction.A 29-year-old man with extrahepatic portal vein obstruction who underwent variceal eradication by sclerotherapy six years ago, was admitted with hypotension and abdominal pain. Abdominal paracentesis yielded frank blood. laparotomy showed bleeding from a large ectopic vessel along the splenorenal ligament. The vessel was ligated and the patient recovered.- - - - - - - - - - ranking = 0.77848701802812keywords = vessel (Clic here for more details about this article) |
7/143. Remote vascular catastrophes after neurovascular interventional therapy for type 4 ehlers-danlos syndrome.Type 4 ehlers-danlos syndrome (EDS 4) is the most malignant form of ehlers-danlos syndrome, often accompanied by neurovasacular complications secondary to vessel dissection or aneurysms. The fragile nature of connective tissue in these patients makes exovascular and endovascular treatment hazardous. We have treated four patients with EDS 4 over the last 8 years by using neuroendovascular procedures. Two of these individuals suffered remote vascular injuries around the time of their procedures and ultimately died. The circumstances surrounding their deaths will make up the body of this report.- - - - - - - - - - ranking = 0.38924350901406keywords = vessel (Clic here for more details about this article) |
8/143. Acute mitral regurgitation from ruptured chordae tendineae in systemic lupus erythematosus.A patient with systemic lupus erythematosus developed acute mitral regurgitation due to ruptured chordae tendineae, requiring mitral valve replacement. Typical changes of Libman-Sacks endocarditis were observed in the excised mitral valve. Immunofluorescent studies revealed antinuclear antibody and deposits of immunoglobulins and complement within small vessels.- - - - - - - - - - ranking = 0.38924350901406keywords = vessel (Clic here for more details about this article) |
9/143. Stress-related primary intracerebral hemorrhage: autopsy clues to underlying mechanism.BACKGROUND: research into the causes of small-vessel stroke has been hindered by technical constraints. Cases of intracerebral hemorrhage occurring in unusual clinical contexts suggest a causal role for sudden increases in blood pressure and/or cerebral blood flow. CASE DESCRIPTION: We describe a fatal primary thalamic/brain stem hemorrhage occurring in the context of sudden emotional upset. At autopsy, the brain harbored several perforating artery fibrinoid lesions adjacent to and remote from the hematoma as well as old lacunar infarcts and healed destructive small-vessel lesions. CONCLUSIONS: We postulate that the emotional upset caused a sudden rise in blood pressure/cerebral blood flow, mediating small-vessel fibrinoid necrosis and rupture. This or a related mechanism may underlie many small-vessel strokes.- - - - - - - - - - ranking = 1.5569740360562keywords = vessel (Clic here for more details about this article) |
10/143. rupture of pseudointima in an implanted vascular prosthesis: immunohistological study of plasminogen activators and matrix metalloproteinases.We investigated late-onset anastomotic stenosis in an implanted prosthetic graft. rupture of the pseudointima and hemorrhaging from the vasa vasorum were observed at the border of the collagenous tissue and fibrin layer. An immunohistological study showed that the fibrin layer was positive for tPA, but weakly positive for PAI-1. Some neutrophils and monocyte/macrophages in the fibrin layer were immunostained for tPA, uPA, uPAR, and MMP-1, -2 and -3. Some spindle-shaped cells surrounding the graft were immunostained for uPA, uPAR, MMP-1, -2, -3, -7 and -9, and TIMP-1 and -2. The endothelial cells of some microvessels were positive for MMP-1 and -2, and tPA. Some multi-nucleated giant cells were immunostained for MMP-7 and-9, tPA, PAI-1, uPA, and uPAR. Overexpressed MMPs and PAs possibly caused instability of the pseudointima.- - - - - - - - - - ranking = 0.38924350901406keywords = vessel (Clic here for more details about this article) |
