1/11. Pulmonary capillary hemangiomatosis: report of a case and review of the literature.We describe a case of pulmonary capillary hemangiomatosis in a 60-year-old woman with a 1-year history of progressive exertional dyspnea. Four years before admission a diagnosis of breast cancer was made, and she underwent mastectomy plus radiation therapy and treatment with oral antiestrogens. The chest X-ray showed bilateral interstitial infiltrates. Pulmonary function studies revealed a severe restrictive pattern. Abundant red blood cells were found in the bronchoalveolar lavage fluid. On the basis of open lung biopsy, interstitial fibrosis was diagnosed. cardiac catheterization revealed pulmonary hypertension. steroids were prescribed, but the patient's condition continued to deteriorate and she died approximately 3 years after presentation. The identification of proliferating and invasive capillaries, which are unique to pulmonary capillary hemangiomatosis, led to the correct diagnosis at autopsy.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
2/11. hemangioma of the right ventricle causing outflow tract obstruction.A 3 1/2-year-old child had a murmur of pulmonary stenosis. echocardiography and cardiac catheterization revealed a pulmonary infundibular obstruction. magnetic resonance imaging of the heart demonstrated a mass in the interventricular septum. The mass was successfully resected and a pathologic diagnosis of capillary hemangioma was made. Only two previous cases of hemangioma causing right ventricular outflow obstruction have been reported; both of these cases involved adults. This case represents the first report of a hemangioma causing right ventricular outflow tract obstruction in a child. An exploratory operation with resection is the treatment of choice.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
3/11. Superselective angiography with digital subtraction and embolization of a maxillary hemangioma in a patient with Eisenmenger's syndrome.Central maxillofacial hemangiomas can represent diagnostic and therapeutic problems. The concurrent existence of Eisenmenger's complex in the presented case added an anesthetic challenge. The development of superselective arterial catheterization and digital subtraction angiography has been instrumental in improving the ability of clinicians to diagnose and effectively manage vascular lesions, especially in the maxillofacial region. Embolization remains an excellent adjunctive therapy for vascular processes.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
4/11. Pulmonary capillary hemangiomatosis.We report a case of pulmonary capillary hemangiomatosis affecting a 35-yr-old Caucasian woman. Progressive pulmonary hypertension was documented by serial cardiac catheterizations, and pulmonary function studies showed changes suggestive of chronic pulmonary congestion. Although a difficult condition to diagnose during life as it may mimic veno-occlusive disease, capillary hemangiomatosis has a distinct histopathologic picture.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
5/11. angiography in vascular malformations of the face.While angiography has been established as a useful procedure in evaluating vascular malformations of the face, the role of selective catheterization has not been stressed. Five patients with either capillary-cavernous hemangiomas or arteriovenous racemose hemangiomas were selected to illustrate the angiographic features of vascular malformations of the face as well as problems in angiographic evaluation and therapeutic techniques. Angiographic studies were valuable in establishing the extent and type of hemangioma, its blood supply and drainage, and associated intraorbital or intracranial extensions. We believe that selective catheterization is essential in preoperative evaluation of facial hemoangiomas, particularly in detecting unsuspected intracranial involvement.- - - - - - - - - - ranking = 2keywords = catheterization (Clic here for more details about this article) |
6/11. Experiences in the endovascular treatment of cerebral arteriovenous angiomas.Percutaneous superselective balloon catheterization for the treatment of large cerebral arteriovenous malformations, for which direct operation is infeasible, is described. Both a detachable balloon technique and a "calibrated leak" free embolization have been applied, based on a new hardening silicone material elaborated by the authors. The experiences of operations performed since 1978 are represented by four selected case studies.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
7/11. Management of vascular soft tissue neoplasms using transcatheter embolization and surgical excision.Preoperative embolization of highly vascular soft tissue tumors was performed in four patients. Selective catheterization of branch vessels supplying the tumors successfully avoided inadvertent embolization of adjacent normal tissue. Operative blood loss was significantly less than anticipated, permitting an easier, more precise, and quicker operation. Two of the lesions were benign intramuscular hemangiomas; one was a fibrosarcoma, and one, a malignant schwannoma. Three tumors were resected completely. A small portion of one hemangioma could not be removed. All patients were free of recurrence during follow-up periods of 6 to 14 months.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
8/11. Aorto-atrial fistula following internal jugular vein catheterization.A 48-year-old woman with giant haemangioma of the liver underwent percutaneous transjugular placement of a stent in the left hepatic vein for relief of an obstruction due to the compression of the benign liver tumour. Following the procedure, paroxysmal atrial fibrillation occurred and right-sided heart failure gradually appeared. echocardiography and cardiac catheterization demonstrated a fistula between the aortic root and the right atrium, that was confirmed on surgery.- - - - - - - - - - ranking = 5keywords = catheterization (Clic here for more details about this article) |
9/11. Mesothelial/monocytic incidental cardiac excrescences: cardiac mice.We have identified four new cases of the cardiac lesion resembling a histiocytoid (epithelioid) hemangioma from the consultation and surgical pathology files of the Mayo Clinic from 1979 to 1992. The lesions occurred in two men and two women, mean age 60 yr (range, 55 to 63), three of whom had undergone previous cardiac catheterization. All were found incidentally, two as separate tissue fragments obtained by right ventricular endomyocardial biopsy during investigations for dilated cardiomyopathy, and two during mitral valve replacement (one free floating in the left atrium and the other attached to the mitral valve). The latter two lesions measured 1.0 and 0.8 cm. All were composed of histiocytes (macrophages) focally admixed with cuboidal cells which formed strips and tubular arrays in three cases. immunohistochemistry (two cases) confirmed their biphasic nature with cytokeratin positivity of the cuboidal cells and CD68 (KP-1) positivity (macrophage-myeloid lineage) of the histiocytes. carcinoembryonic antigen and Leu-M1 were negative for both cell types. Transmission electron microscopy (two cases) showed macrophage-like cells and cuboidal cells with intracytoplasmic intermediate filaments, desmosome-like cellular junctions, and rough endoplasmic reticulum consistent with mesothelial cells. All four patients had a benign clinical course (range, 2 mo to 13 yr). This mesothelial and monocytic (histiocytic) process is postulated to relate to previous cardiac catheterization (applicable in three of our patients). The importance of these nodules, which are likely reactive, is their potential confusion with metastatic adenocarcinoma. We propose the name mesothelial/monocytic incidental cardiac excresences (cardiac mice) for these lesions.- - - - - - - - - - ranking = 2keywords = catheterization (Clic here for more details about this article) |
10/11. Cellular hemangioma of the posterior mediastinum: unusual presentation of a rare vascular neoplasm.Cellular hemangiomas arising in the posterior mediastinum (or paravertebral sulcus) are rare tumors even in childhood. We report one such tumor which arose within a sympathetic ganglion in an infant with associated congenital heart disease (ventricular septal defect) and severe congestive heart failure. The tumor was discovered incidentally at cardiac catheterization when tumor blush was observed in the apex of the left chest. This benign mass was completely resected prior to repair of the cardiac defect. We speculate that it may have contributed to the congestive heart failure.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
