METHODS: The clinical data from 28 patients, who underwent hepatic resection requiring intraoperative autologous transfusion with the cell-saver apparatus, were analyzed retrospectively. The tumors in the 28 patients involved the proximal hepatic veins and inferior vena cava. The diameters of these hemangiomas ranged from 12x15 cm to 18-40 cm. All patients had varying degrees of THVE. ' RESULTS: The 28 patients with hemangioma received integrated resection and recovered. One patient had rupture of tumors resulting in massive hemorrhage of 6000 ml during liver resection; 4 patients had blood transfusions of 400-800 ml; the other 23 patients had no blood transfusion. Only 6 patients underwent the Pringle maneuver with resection. The other 22 patients underwent THVE during the liver resection. The interval of THVE was 5-30 minutes (mean 16 minutes). CONCLUSIONS: Intraoperative autologous transfusion during modified, normal-temperature THVE for extracapsular resection of huge hepatic cavernous hemangioma is feasible.展开更多

METHODS: To observe the relation of cavernous hemangioma of the liver to the hepatic artery and portal vein, we performed serial selective hepatic arteriography in 22 patients. Five patients after ligation of the right hepatic arteries underwent portography and liver staining by in jection of methylene blue into the portal veins and 2 patients had hepatic specimens resected, which were made into a model cast by filling the hepatic veins (yellow) and portal venous branches (blue) with methyl methacrylate after vascular lavage. RESULTS: Serial selective hepatic arteriography showed that hepatic arteries and hemangioma were displayed simultaneously, and that hemangioma was supplied by one to numerous arterial branches. In the portal phase of portography, contrast medium failed to enter the tumor and the intrahepatic branches of the portal vein were pushed aside by the tumor; in the liver parenchymal phase, however, the tumor appeared to be a low-density area. Hepatic arteriography and portography revealed that the fistula between the artery and portal vein may not be existed. The liver stained with methylene blue showed that the normal hepatic parenchyma could be stained with deep blue; in contrast, the tumor was not stained at all. The casting specimens showed that the eroded tumor left a round vacant area because of its total shedding, and no blue stained branches of the portal vein extended into the tumor. CONCLUSION: Blood supply of CHL may originate from the hepatic artery.展开更多

The patient had a history of a giant hepatic cavernous hemangioma. Emergency exploratory laparotomy was performed for suspected intra-abdominal bleeding with abdominal compartment syndrome, and more than 4 liters of blood and blood clots were removed. An active bleeding laceration (5 cm) of a hepatic cavernous hemangioma was detected in segment III of the liver. The bleeding was controlled by sutures, Teflon patches and tamponade. The abdomen was closed temporarily using the vacuum-assisted method. Because of the presence of persistent fresh blood through abdominal drainage at a rate of 〉1 L/h, splenectomy was performed to control the bleeding again by sutures and Teflon patches. Finally, the abdomen was closed using a biologic mesh. The patient was discharged home 30 days after trauma. Bleeding of trauma-caused hepatic hemangioma is rare, but splenic injury due to blunt abdominal trauma is common. An in-depth investigation is necessary to avoid second intervention.展开更多

METHODS: A total of 97 patients with pathologically confirmed CH in the orbit were examined with axial and coronal CT scan, and axial, coronal, sagittal, and enhanced fat suppression MRI scan. CT and MRI findings and intraoperative adhesion degrees were retrospectively analyzed. RESULTS: There were 47 patients with slight adhesion, for whom CT and MRI showed round masses with well defined margins in the extraocular muscles; 14 patients with mild adhesion, for whom CT and MRI revealed irregular masses with unclear boundary between CH and the optic nerve in coronal images, and emissary veins in the posterior region of masses in contrast-enhanced images; 36 patients with severe adhesion, for whom CT and MRI exhibited an irregular or ovoid mass filling the orbital apex, or showed distorted and even spiky margins in the posterior region of masses in contrast enhanced images at the presence of a transparent triangle between the mass and the orbital apex. CONCLUSION: Preoperative CT and MRI aid in accurate diagnosis, selection of the surgical approach, and assessment of the adhesion degree and surgical risks for CH.展开更多

Methods Six cases of spinal cord cavernous heman-gioma diagnosed by MRI and confirmed by pathology were reviewed. The characteristics of MRI were analyzed and correlated with pathological characteristics of spinal cord cavernous hemangioma. Results In 4 cases, the tumors were located in thoracic segment of the spinal cord and 2 in cervical cord. All lesions were solitary and the spinal cords were normal or a little thicker. The MRI showed that the images of focus were ball-like popcorn or mulberry with mixed signal,with short T2 signal around the focus. Under microscope, the hemangioma was composed of highly expanded blood sinusoids and its wall was thin and consisted of flat epithelial cells. There were some red blood cells in the cavity of the sinusoid and a little fibrous tissue in the diazoma between blood sinusoids. And also some fresh and old hemorrhages could be seen in the specimen. Conclusion MRI has high sensitivity and specificity in the diagnosis of spinal cavernous hemangioma.展开更多

The term “giant cerebral cavernous malformations” still does not have a clear definition in the literature, with a wide variety of results. It is known, however, that there is an association between the size of the cavernoma and postoperative sequelae, especially in those with a size greater than 3 cm in its largest diameter. We present a case report of resection of a giant brain cavernoma measuring approximately 8 cm in its largest diameter, emphasizing on clinical presentation, diagnoses and postoperative evolution. Additionally, we performed a comprehensive review of the existing literature on the subject, addressing the epidemiology, pathophysiology, diagnostic methods, treatment options, and prognosis associated with this condition.展开更多

The present review aims to clarify the appropriateness of the size category "giant" for liver heman- gioma. DATA SOURCES: We reviewed the reports on the categoriza- tion of hemangioma published between 1970 and 2014. The number of hemangiomas, size criteria, mean and range of hemangioma sizes, and number of asymptomatic and symp- tomatic patients were investigated in patients aged over 18 years. Liver hemangiomas were divided into four groups: 〈5.0 cm, 5.0-9.9 cm, 10.0-14.9 cm and 〉15.0 cm in diameter. Inclu- sion criteria were noted in 34 articles involving 1972 (43.0%) hemangiomas (〉4.0 cm). RESULTS: The patients were divided into the following groups: 154 patients (30.0%) with hemangiomas less than 5.0 cm in diameter (small), 182 (35.5%) between 5.0 cm and 9.9 cm (large), 75 (14.6%) between 10.0 and 14.9 cm (giant), and 102 (19.9%) more than 15.0 cm (enormous). There were 786 (39.9%) asymptomatic patients and 791 (40.1%) symptomatic patients. Indications for surgery related to symptoms were reported in only 75 (3.8%) patients. Operations including 137 non-anatomical resection (12.9%) and 469 enudeation (44.1%) were undearly related to size and symptoms.CONCLUSIONS: The term "giant" seems to be justified for liver hemangiomas with a diameter of 10 cm. Hemangiomas categorized as "giant" are not indicated for surgery. Surgery should be performed only when other symptoms are apparent.展开更多

There have been a few case reports about small bowel autotransplantation combined with pancreatoduodenectomy for enormous mesenteric cavernous hemangioma of small intestine. The present surgical methods for enormous cavernous bemangioma of the small intestine mesentery mainly included tumor excision and/or small bowel resection. However, these therapies are not effective for those patients in whom the angiocavemoma has infiltrated the mesenteric artery or pancreas, and these patients often give up therapy. It is recognized that enormous cavernous hemangioma of the small intestine mesentery is a benign lesion, and patients may have an excellent prognosis after complete resection of the lesion.展开更多

文摘BACKGROUND: This paper was to review the effects of intraoperative autologous transfusion during modified, normal-temperature, total hepatic vascular exclusion (THVE) for extracapsular resection of giant hepatic cavernous hemangioma. METHODS: The clinical data from 28 patients, who underwent hepatic resection requiring intraoperative autologous transfusion with the cell-saver apparatus, were analyzed retrospectively. The tumors in the 28 patients involved the proximal hepatic veins and inferior vena cava. The diameters of these hemangiomas ranged from 12x15 cm to 18-40 cm. All patients had varying degrees of THVE. ' RESULTS: The 28 patients with hemangioma received integrated resection and recovered. One patient had rupture of tumors resulting in massive hemorrhage of 6000 ml during liver resection; 4 patients had blood transfusions of 400-800 ml; the other 23 patients had no blood transfusion. Only 6 patients underwent the Pringle maneuver with resection. The other 22 patients underwent THVE during the liver resection. The interval of THVE was 5-30 minutes (mean 16 minutes). CONCLUSIONS: Intraoperative autologous transfusion during modified, normal-temperature THVE for extracapsular resection of huge hepatic cavernous hemangioma is feasible.

文摘Cerebral cavernous malformations are a rare and congenital vascular malformation that can present as a challenge in neurosurgical management. The term “giant cerebral cavernous malformations” still does not have a clear definition in the literature, with a wide variety of results. It is known, however, that there is an association between the size of the cavernoma and postoperative sequelae, especially in those with a size greater than 3 cm in its largest diameter. We present a case report of resection of a giant brain cavernoma measuring approximately 8 cm in its largest diameter, emphasizing on clinical presentation, diagnoses and postoperative evolution. Additionally, we performed a comprehensive review of the existing literature on the subject, addressing the epidemiology, pathophysiology, diagnostic methods, treatment options, and prognosis associated with this condition.
文摘BACKGROUND: Four different sizes (4, 5, 8 and 10 cm in diameter) can be found in the literature to categorize a liver hemangioma as giant. The present review aims to clarify the appropriateness of the size category "giant" for liver heman- gioma. DATA SOURCES: We reviewed the reports on the categoriza- tion of hemangioma published between 1970 and 2014. The number of hemangiomas, size criteria, mean and range of hemangioma sizes, and number of asymptomatic and symp- tomatic patients were investigated in patients aged over 18 years. Liver hemangiomas were divided into four groups: 〈5.0 cm, 5.0-9.9 cm, 10.0-14.9 cm and 〉15.0 cm in diameter. Inclu- sion criteria were noted in 34 articles involving 1972 (43.0%) hemangiomas (〉4.0 cm). RESULTS: The patients were divided into the following groups: 154 patients (30.0%) with hemangiomas less than 5.0 cm in diameter (small), 182 (35.5%) between 5.0 cm and 9.9 cm (large), 75 (14.6%) between 10.0 and 14.9 cm (giant), and 102 (19.9%) more than 15.0 cm (enormous). There were 786 (39.9%) asymptomatic patients and 791 (40.1%) symptomatic patients. Indications for surgery related to symptoms were reported in only 75 (3.8%) patients. Operations including 137 non-anatomical resection (12.9%) and 469 enudeation (44.1%) were undearly related to size and symptoms.CONCLUSIONS: The term "giant" seems to be justified for liver hemangiomas with a diameter of 10 cm. Hemangiomas categorized as "giant" are not indicated for surgery. Surgery should be performed only when other symptoms are apparent.
文摘Recent advances in transplantation techniques have allowed pancreatoduodenectomy, distal gastrectomy,hemicolectomy and small bowel autotransplantation to be the therapy of choice for enormous cavernous hemangioma of the small intestine mesentery. There have been a few case reports about small bowel autotransplantation combined with pancreatoduodenectomy for enormous mesenteric cavernous hemangioma of small intestine. The present surgical methods for enormous cavernous bemangioma of the small intestine mesentery mainly included tumor excision and/or small bowel resection. However, these therapies are not effective for those patients in whom the angiocavemoma has infiltrated the mesenteric artery or pancreas, and these patients often give up therapy. It is recognized that enormous cavernous hemangioma of the small intestine mesentery is a benign lesion, and patients may have an excellent prognosis after complete resection of the lesion.
文摘Severe diffuse cavernous hemangioma of the lower limb is rarely seen among young people and sometimes can be a fatal challenge for operation.We reported a case of diffuse cavernous hemangioma invol-ving both skin and muscles of the left lower limb and perineal region in an adolescent patient.The patient who had previously undergone a local hemangioma resection of the foot ultimately ended in superficial femoral artery ligation and supergenual thigh amputation of the left upper leg because of uncontrollable massive bleeding of anastomotic stoma.
文摘Dear editor:Cavernous hemangioma is an extremely rare disease in female genital tract,most of which diffusely involves the myometrium.Localized cavernous hemangioma of the uterus is even more uncommon.We hereby report a new bona file case of endometrial cavernous hemangiomatous polyp in a 34-yr-old woman.The diagnosis of this patient was confirmed by histopathologic examination.This case is of interest because it indicates that this condition could be found in the vagina,mimicking cervical polyp.Based on previous research articles,1,2 this is the third report of endometrial cavernous hemangiomatous polyp,and it is also the first reported one that presenting as a cervical polyp.Clinicians should keep in mind that a cervical lesion may not only originate from the cervix,rather,the differential diagnosis should be broadened to include cavernous hemangioma,especially when bleeding occurs.
