1/183. Aortic dissection in young patients with chronic hypertension.We describe four patients aged 14 to 21 years who developed acute aortic dissection. In three of the four patients, the course was fatal, despite aggressive medical and surgical intervention. All four patients had sustained systemic hypertension related to chronic renal insufficiency. The patients had no other identifiable risk factors for aortic dissection, including congenital cardiovascular disease, advanced atherosclerosis, vasculitis, trauma, pregnancy, or family history of aortic dissection. Although aortic dissection is rare in individuals younger than 40 years of age, young patients with sustained systemic hypertension are at increased risk for this serious and often fatal condition. physicians must be aware of this rare complication of hypertension and consider aortic dissection in the differential diagnosis of unusual chest, abdominal, and back pain in hypertensive children, adolescents, and young adults.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
2/183. Renal granulomatous sarcoidosis in childhood: a report of 11 cases and a review of the literature.We analysed retrospectively 11 children with renal granulomatous sarcoidosis confirmed by renal histology in order to describe the course and prognosis of the disease. Symptomatic sarcoidosis was diagnosed at a mean age of 10.1 years. Nine children had renal involvement at the time of diagnosis. In the course of the disease, nine patients developed renal failure and mild proteinuria, seven had transient sterile leukocyturia, four showed microscopic haematuria, seven had a urinary concentrating defect, and enlarged kidneys were seen in three patients. One child had hypercalcaemia and hypercalciuria, none had hypertension. light microscopy of the kidney showed interstitial infiltration by mononuclear cells in all children, interstitial fibrosis in nine patients, epithelioid granulomas in seven, tubular involvement in eight, and mild glomerular involvement in seven patients. Renal immunofluorescence was negative. Ten children received prednisone for 1-11 years. After a mean follow up of 5.5 years, three patients had entered end-stage renal failure and one had chronic insufficiency after interruption of medical supervision and prednisone therapy. CONCLUSION: Renal failure, proteinuria, leukocyturia, haematuria, and concentration defect are the prominent features of renal granulomatous sarcoidosis in children. Steroid therapy, adjusted according to disease activity, may prevent end-stage renal failure.- - - - - - - - - - ranking = 0.14285714285714keywords = hypertension (Clic here for more details about this article) |
3/183. Visualization of functional improvement by 123I-IMP lung SPET after thromboendarterectomy for chronic pulmonary embolism.We report on six patients with chronic pulmonary embolism who underwent 123I-IMP and 99Tcm-MAA lung SPET before and after thromboendarterectomy. 123I-IMP lung SPET can assess the viability of lung parenchyma, because it is a non-particulate agent that accumulates in the endothelial membranes of pulmonary capillaries. Chronic pulmonary thromboembolism accompanied by pulmonary hypertension has a poor prognosis that may be improved only by thromboendarterectomy. We compared 123I-IMP and 99Tcm-MAA lung SPET in terms of functional improvement after such surgery. After thromboendarterectomy, all six patients were functionally improved, according to the criteria of the new york heart association. The pre- and post-surgery percentage of vascular obstruction did not differ significantly with 99Tcm-MAA lung SPET (44.8 /- 11.2% and 32.5 /- 15.6% pre- and post-surgery, respectively). In contrast, 123I-IMP lung SPET revealed a significant pre- versus post-surgery difference (15.5 /- 9.5% and 3.3 /- 5.9% pre- and post-surgery, respectively). 123I-IMP lung SPET could be useful for evaluating thromboendarterectomy because pulmonary parenchymal viability owing to arterial microvasculature can be estimated.- - - - - - - - - - ranking = 0.14285714285714keywords = hypertension (Clic here for more details about this article) |
4/183. Incomplete nondisplaced tibial osteotomy for treatment of osteoarthritic knee pain.Intraosseous venous hypertension is considered a significant factor in the production of knee pain secondary to degenerative arthrosis, thus vascular decompression by means of tibial osteotomy is a rational option for treatment of selected patients. A preliminary report is presented of six patients with symptoms of primary or secondary degenerative arthrosis who were treated by incomplete nondisplaced proximal tibial osteotomy with good or excellent results. These patients were refractory to nonoperative treatment and were not deemed suitable candidates for angulated osteotomy, arthroscopic surgery alone, or total knee arthroplasty. patients ranged in age from 36 to 61 years (mean age: 47 years). Follow-up ranged from .8 to 6.7 years (mean: 3.1 years). The subjects were studied postoperatively by interview, physical examination, radiographs, and bone scans. Results were assessed using the knee rating system of The Hospital for Special Surgery.- - - - - - - - - - ranking = 0.14285714285714keywords = hypertension (Clic here for more details about this article) |
5/183. A rare complication of renal biopsy in a child with membranoproliferative glomerulonephritis.Percutaneous renal biopsy is essential for the definitive diagnosis of chronic glomerulonephritis. Large arteriovenous fistula (AVF) which is a rare complication of native renal biopsy is generally diagnosed in the first weeks after the procedure. We present a childhood membranoproliferative glomerulonephritis case with an enormous AVF presenting with severe hypertension 15 months after the biopsy that was successfully embolized. In conclusion, AVF must be considered in children having chronic glomerulonephritides even if hypertension appears late after the renal biopsy.- - - - - - - - - - ranking = 0.28571428571429keywords = hypertension (Clic here for more details about this article) |
6/183. A successful case of pulmonary thromboendarterectomy for chronic thromboembolic pulmonary hypertension with a thrombus in the right ventricle.Chronic thromboembolism is a frequent cause of progressive hypertension and carries a poor prognosis. Medical treatment is not effective and surgery provides the only potential for a cure at present. We herein report a successful case of thromboendarterectomy treated via a median sternotomy with intermittent circulatory arrest. A 43-year-old man was admitted to our hospital complaining of progressive dyspnea, edema of the lower extremities, and a fever with an unknown origin. A subsequent definitive evaluation showed him to be suffering from surgically accessible chronic thromboembolic pulmonary hypertension with a thrombus in the right ventricle. He underwent a pulmonary thromboendarterectomy and thrombectomy via a median sternotomy with intermittent circulatory arrest on November 24, 1994. Postoperatively he showed a marked improvement in his hemodynamic status and blood gas analysis. He has also returned to work with no trouble. Deep vein thrombosis appeared to be the pathogenesis of this case, but we could not find the origin of his unknown fever. He is currently being controlled by treatment with methylprednisolone as before.- - - - - - - - - - ranking = 0.85714285714286keywords = hypertension (Clic here for more details about this article) |
7/183. Improvement of pulmonary hypertension after liver transplantation.Pulmonary hypertension at the end stage of chronic liver disease is not an uncommon situation. This association termed portopulmonary hypertension raises the question of the feasibility of performing orthotopic liver transplantation (OLT). In the case reported herein, there was a favorable outcome after OLT, even though the mean pulmonary artery pressure (MPAP) before transplantation was increased to 45 mm Hg. Before OLT, the cardiac index (CI) was considerably elevated (7.69 L/min/m2), giving evidence of a marked hyperdynamic circulatory state. The CI decreased significantly after OLT (3.38 L/min/m2), and this produced a significant decrease in the MPAP. Our observation suggests that portopulmonary hypertension due to a marked increase in the CI can be managed successfully by OLT.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
8/183. Percutaneous endoscopic gastrostomy for continuous feeding in children with chronic cholestasis.BACKGROUND: malnutrition associated with chronic cholestasis in children often requires continuous enteral feeding through a nasogastric tube, which may be poorly tolerated. METHOD: Percutaneous endoscopic gastrostomy was performed in five children (age range, 20 months to 13 years) with severe cholestasis (alagille syndrome in four; biliary atresia in one) and severe malnutrition (mean weight, -2.6 standard deviations; mean height, -2.7 standard deviations) who were awaiting liver transplantation. The pull-through technique was used in patients under general anesthesia, and the button was set within 2 months. RESULTS: Minor wound infection required antibiotic therapy in one patient. In the four children with alagille syndrome, enteral feeding by means of percutaneous endoscopic gastrostomy was used until liver transplantation for a mean period of 14 months with a mean weight gain of 350 g/mo and a mean height gain of 0.53 cm/mo. Seventeen months to 3 years, 3 months after liver transplantation, all four children were alive and in good clinical condition with normal readings in liver function tests. The technique had to be discontinued in the child with biliary atresia because of secondary occurrence of ascites, gastric intolerance, and refractory wound infection. CONCLUSION: Percutaneous endoscopic gastrostomy may be a valuable alternative to nasogastric tube for nutritional support in children with cholestasis and mild portal hypertension.- - - - - - - - - - ranking = 0.14285714285714keywords = hypertension (Clic here for more details about this article) |
9/183. The location of chronic pregnancy hypertension on the vasoconstriction-volume spectrum: working hypothesis.OBJECTIVE: The purpose of this study was to examine whether volume loading is a factor in chronic pregnancy hypertension. STUDY DESIGN: Five patients with chronic hypertension performed home self-monitoring daily with a noninvasive pressure transducer from a fingertip. Determinants of mean arterial pressure were computed from the pressure data and a concurrent electrocardiogram. For this study blood pressure and rapid ejection time, which is an empiric indicator of arterial compliance, were evaluated during antihypertensive therapy. Data were transmitted by facsimile to the hospital. RESULTS: One patient with hypertension who was admitted to the study at 10 weeks' gestation became normotensive with a diuretic (furosemide) alone. Medication was discontinued at 23 weeks' gestation. This patient remained normotensive until delivery at 41 weeks' gestation. blood pressure was controlled with furosemide combined with nifedipine and labetolol in the other 4 cases. Three patients were studied with concurrent blood pressure and rapid ejection time measurements made before and after antihypertensive medication. All 3 showed decreases in these measurements with medication. CONCLUSION: Both volume excess and vasoconstriction should be considered in the pathogenesis of chronic pregnancy hypertension.- - - - - - - - - - ranking = 1.1428571428571keywords = hypertension (Clic here for more details about this article) |
10/183. A case of renal artery stenosis secondary to chronic pancreatitis.We report a case of renal artery stenosis most probably secondary to chronic pancreatitis. The patient had a traumatic pancreatic fistula. This was followed by numerous attacks of pancreatitis in the following years. At a relatively young age, he developed hypertension. Examinations revealed a right renal artery stenosis which was successfully treated by a percutaneous angioplasty. This rare complication should be kept in mind as a possible complication of pancreatitis.- - - - - - - - - - ranking = 0.14285714285714keywords = hypertension (Clic here for more details about this article) |
