Laparoscopic liver resection or enucleation for giant hepatic hemangioma: how to choose?

BACKGROUND: Laparoscopic treatment has been increasingly adopted for giant hepatic hemangioma (HH), but the role of liver resection or enucleation remains uncertain. The aim of this study is to compare the laparoscopic resection (LR) with laparoscopic enucleation (LE) for HH, and to provide evidence on how to choose the most suitable approach for HH. METHODS: A retrospective analysis of HH patients underwent laparoscopic treatment between March 2015 and August 2022 was performed. Perioperative outcomes were compared based on the surgical approaches, and risk factors for increased blood loss was calculated by logistic regression analysis. RESULTS: A total of 127 patients in LR group and 287 patients in LE group were enrolled in this study. The median blood loss (300 vs. 200 mL, P < 0.001) was higher in LE group than that in LR group. Independent risk factors for blood loss higher than 400 mL were tumor size ≥ 10 cm, tumor adjacent to major vessels, tumor occupying right liver or caudate lobe, and the portal phase enhancement ratio (PER) ≥ 38.9%, respectively. Subgroup analysis showed that LR was associated with less blood loss (155 vs. 400 mL, P < 0.001) than LE procedure in patients with high PER value. Both LR and LE approaches exhibited similar perioperative outcomes in patients with low PER value. CONCLUSIONS: Laparoscopic treatment for HH could be feasibly and safely performed by both LE and LR. For patients with PER higher than 38.9%, the LR approach is recommended.

Clinical impact and role of major vessels involvement in laparoscopic resection for hepatic hemangioma.

BACKGROUND: Severe bleeding remains a significant concern in laparoscopic resection for hepatic hemangioma. It is rarely reported that how the degree of major vessels involvement impacts on severe bleeding. The present study primarily aimed to analyze the impacts of the number of involved major vessels (NIMV) during laparoscopic surgery for hepatic hemangioma and evaluate the risk factors associated with increased bleeding. METHODS: A database search was carried out for consecutive patients who underwent laparoscopic resection for liver hemangiomas at our department from January 2018 to December 2023. The collected data included demographics, characteristics of the hemangiomas, laboratory data, operation method, surgical and postoperative variables. RESULTS: A total of 72 patients were enrolled in the study. 42 patients were categorized into the group with NIMV < 2, while 30 patients were divided into the group with NIMV ≥ 2. The group with NIMV ≥ 2 demonstrated a significant correlation with special segments, involved multiple segments and diameter of the hemangiomas (P < 0.01). And the perioperative variables including the extent of resection, operative time, blood loss, Pringle maneuver times, postoperative stay, drainage tube duration, and postoperative liver function (ALT, AST) also showed significant differences between the two groups (P < 0.05). Notably, NIMV ≥ 2 was identified as the most important independent risk factor for intraoperative blood loss ≥ 500 ml in laparoscopic surgery for hepatic hemangioma (P = 0.011). For NIMV ≥ 2, the independent risk factor was special segments in multivariate analysis (P = 0.000). CONCLUSION: The involvement of multiple major vessels (NIMV ≥ 2) was significantly associated with special segments, resulting in increased intraoperative blood loss, operation difficulty, and delayed postoperative recovery. Moreover, it was identified as the single independent risk factor with a considerable risk for increased blood loss during laparoscopic resection for hepatic hemangioma.

Practical surgical technique using the SMISS approach for lip reduction in involuted lip infantile hemangiomas.

BACKGROUND: Lip infantile hemangiomas tend to show less volumetric regression and are more susceptible to visible sequelae in the involuted stage. Some of them still require surgical management after propranolol therapy. This study aimed to evaluate the efficacy and safety of the Stepwise, Multi-Incisional, and Single-Stage (SMISS) approach applied to lip reduction for those with involuted lip hemangiomas. METHODS: A retrospective review was performed to evaluate patients with lip hemangioma who received previous propranolol treatment and underwent the aforementioned procedure. Demographic characteristics, lesion morphology, and medical history were reviewed. The Visual Analog Scale was applied to assess the postoperative appearance. Complications within 12 months postoperatively were recorded. RESULTS: A total of 18 patients with lip hemangioma were eligible. All patients received oral propranolol therapy before surgery, with treatment duration ranging from 6.0 to 23.0 months. Their age at surgery ranged from 2.5 to 9.0 years. The median Visual Analog Scale scores were 8.0, ranging from 4.0 to 10.0. No severe complications were reported. CONCLUSIONS: This modified technique based on the SMISS approach has proven reliable and effective in improving the aesthetic outcome for involuted lip infantile hemangiomas. Practical surgical techniques still play an important part in the propranolol era.

Preoperative elastoplasty of aggressive vertebral hemangiomas in elderly patients: a new strategy for reducing intraoperative bleeding and complications.

PURPOSE: Preoperative elastoplasty could be an alternative strategy for treating aggressive vertebral hemangiomas (VHs) in frail patients needing for spinal cord decompression, combining the advantages of embolization and vertebroplasty. METHODS: Three elderly patients with spinal cord compression from thoracic aggressive VHs underwent XperCT-guided percutaneous injection of silicone (VK100), filling the whole affected vertebra, followed by a decompressive laminectomy. At 12-months follow-up no recurrences, vertebral collapse or segmental kyphosis were noted at the CT scans, with patients reporting an improvement of preoperative neurological deficits, VAS and Smiley-Webster pain scale (SWPS) parameters. RESULTS: With its elastic modulus, non-exothermic hardening, and lower viscosity than PMMA, VK100 allowed a preoperative augmentation of the affected vertebral body, pedicles, and laminae without complications, with a controlled silicone delivery even in part of VH's epidural components thanks to XperCT-guidance. CONCLUSION: When facing highly bony erosive VH encroaching the spinal canal, VK100 combines the advantages of embolization and vertebroplasty especially in elderly patients, permeating the whole VH's angioarchitecture, significantly reducing tumor.

Female Urethral Cavernous Hemangioma: Introducing Treatment and Follow-Up Course of Three Cases.

Cavernous hemangioma is a benign vascular tumor occurring in all parts of the urinary system, including the kidney, bladder, prostate, ureter, and rarely urethra. Urethral cavernous hemangiomas are mostly seen in male patients, and only a few cases of female urethral hemangiomas are reported. Herein, we present the management and follow-up course of 3 cases of female urethral cavernous hemangioma. All 3 cases were menopause women complaining of lower urinary tract symptoms. Definitive diagnosis is made by histopathologic evaluation. In case of large or pedunculated masses, initial surgical resection is highly recommended. Regular follow-up of patients in order to prevent any recurrence is suggested.

Synovial hemangioma presenting with chronic painful infrapatellar mass: a case report.

BACKGROUND: Synovial hemangiomas are rare benign vascular anomalies surrounded by a synovial lining and were first described by Bouchut in 1856. These neoplasms can develop in the intra-articular region, resulting in effusions and knee pain. However, their cause remains unknown. Prompt diagnosis and intervention are critical to prevent chondral damage. Histopathological examination is used to achieve the diagnosis, which is often delayed because of a lack of specific clinical signs. This report describes a unique case in which a painful infrapatellar mass was diagnosed as a synovial hemangioma. The absence of typical magnetic resonance imaging (MRI) findings highlights the importance of arthroscopic excision for diagnosis and symptom relief. CASE PRESENTATION: A 20-year-old woman presented with persistent anterior left knee pain that became exacerbated when she climbed stairs. Despite previous pain management and physical therapy, she developed a painful lump beneath her patella that worsened over time. She had also undergone arthrocentesis, but this did not relieve her pain. Physical examination revealed a palpable, immobile 5-cm mass along the patellar tendon with limited knee flexion and extension and normal ligament stability. T1-weighted fat-saturated MRI of the left knee with gadolinium-based contrast revealed a lobulated intra-articular mass in Hoffa's fat pad that resembled a soft tissue chondroma. A biopsy of the mass was performed to provide histopathological evidence, confirming the benign nature of the mass. The subsequent excisional arthroscopy, combined with incision enlargement for mass removal, confirmed the histopathologic diagnosis of synovial hemangioma based on the presence of numerous dilated blood vessels and venous proliferation within sections of the synovium. Recovery was complete, and no residual tumor was detected on follow-up MRI after 1 year. CONCLUSION: This case study emphasizes the importance of arthroscopic excision over open surgery for patients with synovial hemangioma. The minimally invasive nature of arthroscopy combined with the well-encapsulated nature and location of the mass facilitates complete resection.

Anastomosing hemangioma of the ovary: a rare benign tumor.

Anastomosing hemangioma (AH) is a rare benign lesion that is asymptomatic in the majority of cases. Herein, we present the case of a 26-year-old woman with acute lower abdominal pain for 5 months. The patient subsequently developed symptoms of hyperestrogenism with prolonged menstrual periods. The possibility of malignancy could not be ruled out via ultrasonography and computed tomography. The tumor was completely removed using laparoscopic surgery, and pathological examination confirmed AH of the ovary.

Pediatric intramuscular hemangioma in the submandibular triangle and other musculoskeletal presentations: A pediatric case series.

BACKGROUND: Intramuscular hemangiomas (IMH) account for 0.8 % or less of all benign soft tissue tumors in the general population. Due to their uncommon nature, especially in the head and neck, they are often misdiagnosed and not included in the differential diagnosis. METHODS: This study describes a case series of eleven pediatric patients with a diagnosis of IMH through a retrospective review of the electronic health records and archival records in the Department of Pathology at Children's Hospital of Colorado (CHCO). RESULTS: The index case had a unique presentation in the submandibular triangle, while the remaining ten cases are appendicular and thoracolumbar in nature. CONCLUSIONS: This case series contributes to the sparse scientific literature available regarding IMH, particularly in its head and neck presentation as relevant to otolaryngologists.

Giant Congenital Hemangioma of the Skull: Prenatal Diagnosis and Multimodal Endovascular and Surgical Management.

Introduction: calvarial capillary hemangiomas are vascular tumors rarely seen in newborns. Differential diagnosis may be not straightforward on imaging studies and the management depends on patient and lesion characteristics. Case report: we present the case of a large congenital intracranial extra-axial lesion detected by routine prenatal US screening, a giant calvarial congenital hemangioma, treated with a multimodal strategy. Neonatal MR showed a hemorrhagic solid lesion, causing compression of brain tissue. Conservative treatment was attempted, but a one-month follow-up MR showed growth of the lesion with increased mass effect. Pre-operative endovascular embolization and surgical resection were performed. The pathology was consistent with intraosseous capillary hemangioma. The post-operative course was uneventful. At the 8-month follow-up, the patient had no clinical deficits and MR showed complete resection of the lesion. At the 13-month follow-up, the patient was asymptomatic, showing normal neurological examination and psychophysical development. Conclusions: although wait-and-see policy is feasible for small and asymptomatic lesions, radical resection is indicated when the mass is large, thus causing severe mass effect on the brain. Hypervascularization of the tumor may be responsible for hemorrhagic complications and severe anemia. On these grounds, endovascular treatment is feasible and effective to reduce hemorrhagic complications.

Management of a rapidly enlarging supraclavicular mass of unknown aetiology.

Intramuscular haemangiomas are benign tumours showing an extremely rare occurrence and making up less than 1% of all haemangiomas. The goal of this case report is to share our experience in treating a patient with an extremely rare intramuscular haemangioma, which occurred in the supraclavicular region VB level of the neck and extended towards the infraclavicular space, localised within and inferior to the trapezius muscle. The lesion was diagnosed by using multimodal imaging and a wide excision was performed with intraoperative feeding vessel ligation and a good postoperative result. The main difficulties regarding diagnosis and treatment include a lack of evidence-based guidelines, due to limited publications on this topic, the nature of the lesion frequently showing obscure anatomic localisation deep within muscles and unclear delineation, various anatomic origin requiring an individual treatment approach, inconclusive radiologic signs as well as non-specific symptoms.

Scientific validation of clinical visual scales and Antera 3D™ consistency with derived measurements in the assessment of infantile haemangioma after laser therapy.

BACKGROUND: Laser therapy is a treatment for infantile haemangiomas. The efficacy of laser therapy for red lesions is determined by visual evaluation; however, this assessment is inaccurate and lacks objectivity. OBJECTIVE: To scientifically validate the consistency between pre- and post-treatment visual assessment grades for infantile haemangioma treated with pulsed dye laser (PDL) and the values calculated from images obtained with Antera 3D™. METHODS: This study involved 81 cases of infantile haemangiomas treated with PDL alone from 2012 to 2015 and with Antera 3D™ images of the lesions. Using images obtained before treatment and 4-6 weeks after the last treatment, the lesions were rated using a visual four-step scale. Ratings were categorised as Poor/Fair/Good/Excellent by the degree of improvement in the red colour tone. The red colour ratio was calculated using the haemoglobin distribution in the lesion and surrounding skin, and the improvement difference and improvement rate were then obtained. The correlation between the improvement difference and improvement rate, and visual evaluation was statistically analysed. RESULTS: No serious adverse effects were observed, with an average of 4.3 treatments per patient; 60.1% of the patients achieved Good/Excellent results. There were statistically significant differences in the post-treatment red colour ratio and improvement ratio in each category after visual evaluation classification. The improvement rate and the four visual grades were statistically correlated. CONCLUSION: This study confirmed the scientific validity of visual evaluation and the evaluation criteria calculated from Antera 3D™. This method could objectively determine treatment effectiveness.

Endoscopic Submucosal Dissection: A Safe and Effective Alternative to Surgical Intervention for Esophageal Hemangioma.

BACKGROUND: Hemangiomas represent 3% of all benign esophageal tumors. Conventional esophagectomy is the standard treatment with its invasive nature and possible surgical complications. Now, less invasive techniques are used with better results. Endoscopic submucosal dissection (ESD) is one of the novel noninvasive methods used for en bloc removal of tumors. No available data about the use of ESD in removing esophageal hemangioma. Here, we studied the validity and safety of ESD as a minimally invasive procedure to remove esophageal hemangioma. METHODS: Three patients were diagnosed with esophageal hemangioma and underwent ESD with en bloc resection. Endoscopic ultrasound (EUS) was performed before ESD to better evaluate the layer of origin and vascularity and guard against perforation. Patients were followed up postintervention to document possible complications. RESULTS: Among the 3 studied patients, one presented with chronic abdominal pain, the second was complaining of dysphagia, and the third patient was diagnosed accidentally. Pathology reports confirmed the diagnosis of hemangiomas in all cases with no atypia and complete removal of the lesions. No complications were reported during the procedure or over the follow-up period. CONCLUSIONS: ESD is a proper, minimally invasive method with good en bloc resection that can be used in cases of esophageal hemangiomas.

Littoral cell angioma of the spleen: case report and literature review.

Littoral cell angioma is an extremely rare splenic vascular tumor originating from the cells lining the splenic red pulp sinuses. Approximately 150 cases of littoral cell angioma have been reported since 1991. Its clinical manifestation is usually asymptomatic and is mostly diagnosed as an incidental finding through abdominal imaging. Herein, we present a case of littoral cell angioma in a 41-year-old woman with no previous comorbidities, which initially presented as a nonspecific splenic lesion diagnosed on imaging in the emergency room. The patient was treated through laparoscopic intervention.

Liver Transplantation for Benign Massive Hepatomegaly: Results From a Single Center and Contribution of the Left-to-Right Piggyback Approach.

INTRODUCTION: Polycystic liver disease and giant hepatic hemangioma may present with severe symptom burden and indicate orthotopic liver transplantation. The left-to-right piggyback approach is a useful technique for performing total hepatectomy of enlarged livers. OBJECTIVE: The purpose of this study is to analyze the results of liver transplantation in patients with benign massive hepatomegaly. METHODS: This is a single-center retrospective study involving all adult patients who underwent liver transplantation due to benign massive hepatomegaly from January 2002 to June 2023. RESULTS: A total of 22 patients underwent liver transplantation (21 cases of polycystic live disease and 1 case of giant hepatic hemangioma). During the same time, there were 2075 transplants; therefore, benign massive hepatomegaly accounted for 1.06% of cases. Most patients (59.09%) were transplanted using the left-to-right piggyback technique. Seven patients had previous attempted treatment of hepatic cysts. Another patient previously underwent bilateral nephrectomy and living-donor kidney transplantation. Among these patients, in 5 cases there were massive abdominal adhesions with increased bleeding. Four of these 8 patients died in the very early perioperative period. In comparison to patients without previous cysts manipulation, massive adhesions and perioperative death were significantly higher in those cases (62.5 vs 0%, P = .002 and 50% vs 0%, P = .004, respectively). CONCLUSION: Liver transplantation due to polycystic liver disease and giant hemangioma is a rare event. Total hepatectomy is challenging due to the enlarged native liver. The left-to-right piggyback technique is useful, because it avoids vena cava twisting and avulsion of its branches. Massive adhesions due to previous cysts manipulation may lead to increased bleeding, being a risk factor for mortality.

Aggressive vertebral hemangiomas contain no adipose tissue resulting in thoracic spine kyphosis: A case report.

RATIONALE: Aggressive vertebral hemangiomas (AVHs) destroy continuous vertebral bodies and intervertebral discs and resulting in spinal kyphosis is extremely rare. The very aggressive behavior was attributable to its significant vascular component and contained no adipose tissue. PATIENT CONCERNS: We report a case of thoracic spine kyphosis of AVHs with multiple vertebral bodies and intervertebral disc destruction in a 45-year-old woman. DIAGNOSES: Based on the imaging studies, the patient underwent surgical removal of this lesion and spinal reconstruction. Histopathology consistent with vertebral hemangioma and contained no adipose. INTERVENTIONS: The patient underwent surgical removal of the lesion and spinal reconstruction. After subperiosteal dissection of the paraspinal muscles and exposure of the laminae, the laminae of the T5-7 vertebrae were removed and exposing the lesion. The lesion was soft and showed cystic changes, completely curetted and autogenous bone was implanted. Vertebroplasty was performed through T3-T9 pedicles bilaterally. Pedicle screw fixation was performed for segmental fixation and fusion. OUTCOMES: After 9 days of operation, the incision healed cleanly and free of pain. She was discharged in good general condition. The patient remained asymptomatic after follow-up 6 months of postoperative. LESSONS: AVHs destroy multiple vertebral bodies and intervertebral discs and resulting in spinal kyphosis is extremely rare.

Percutaneous Vertebroplasty for Cervical Symptomatic Hemangiomas and Spinal Metastases: A Case Series and Literature Review.

OBJECTIVE: Percutaneous vertebroplasty (PVP) is a commonly used technique for the treatment of spinal diseases, but it is rarely employed for cervical lesions. This study presents a case series and a literature review to evaluate the efficacy of cervical PVP. METHODS: From August 2013 to January 2023, 14 patients underwent cervical PVP in the author's institution. The mean postoperative follow-up time was 20.3 ± 12.1 months (ranging from 5 to 41 months). The pain status and quality of life were assessed preoperatively, postoperatively, and during follow-up using the Visual Analog Scale and Neck Disability Index. Additionally, complications that occurred during the study period were documented. RESULTS: The series of cases included 9 cases of hemangiomas and 5 cases of spinal metastases. The common symptom was axial pain in the neck. All patients were successfully treated with PVP. Visual analog scale scores decreased from 6.6 ± 0.8 preoperatively to 1.9 ± 0.8 at 24 hours postoperatively and to 2.4 ± 1.2 at the last follow-up (P < 0.01). Neck Disability Index decreased from 22.3% ± 8.9% preoperatively to 7.6% ± 8.1% at 24 hours postoperatively and to 6.0% ± 7.2% at 12-month follow-up (P < 0.01). After the operation, a case of dysphagia occurred, but no major complications were observed during the follow-up period. CONCLUSIONS: Cervical PVP via the anterolateral approach is a safe option for the treatment of cervical symptomatic hemangiomas and spinal metastases with limited invasiveness. It is effective in relieving pain and improving quality of life.

Vertebral Hemangiomas: Yucesoy-Yilmaz Classification System with Corresponding Therapeutic Options.

OBJECTIVE: Vertebral hemangiomas (VHs) are relatively common, symptomatic benign tumors of the spine with a reported estimated incidence up to 11%. They usually appear in the body of the vertebrae; however, they can extend into pedicles, laminae, and epidural space. They may cause pain, neurologic deficits. and fractures. METHODS: In this retrospective, single-center study, we reviewed our cases with VH and we propose the novel classification system that evaluates these lesions per their views on magnetic resonance imaging and clinical findings under 4 main categories. RESULTS: Our novel classification system proposes that grade I lesions occupy less than 50% of the vertebral body, whereas grade II lesions occupy more than 50% and grade III lesions occupy the whole corpus. Grade IV lesions show an epidural and pedicular extension. We propose that grade I lesions may not be worthwhile for follow-up, whereas asymptomatic grade II (a) lesions to be worthy for a biannual imaging and symptomatic thoracolumbar grade II (b) and thoracolumbar grade III lesions to be considered for percutaneous vertebroplasty. We imply that decompression, posterior spinal instrumentation, and open vertebroplasty may be performed for thoracolumbar grade IV lesions. We further consider cervical grade IIb, III, and grade IV lesions as operable because of the disadvantages of percutaneous vertebroplasty. CONCLUSIONS: We suggest that our novel classification system may be useful for the determination of diagnostic and therapeutic procedures in the management of VH. Further multicentric trials on larger series are warranted to validate this system and popularize its utility in larger populations.

Intraosseous hemangioma with aneurysmal bone cyst-like changes of the hyoid bone: Case report and literature review.

RATIONALE: Intraosseous hemangioma is a rare benign vascular tumor of the bone that can affect any body part; however, the most common site is the vertebra, followed by calvarial bones. PATIENT CONCERNS: We present a case of intraosseous hemangioma in a 23-year-old male who presented a feeling of fullness in the throat for 3 months. The hyoid bone level had a hard mass of about 5 cm. Fine needle aspiration showed 5 mL dark bloody aspirates. Magnetic resonance image showed a 5.3 cm mixed signal intensity lesion in the hyoid body. DIAGNOSIS: Histopathologic examination showed intraosseous hemangioma with aneurysmal bone cyst (ABC)-like changes in the hyoid bone. INTERVENTIONS: The mass was completely removed without significant problems. OUTCOMES: Complete mass excision and symptomatic improvements were achieved, and no subsequent relapses were observed. LESSONS: The authors experienced a case of intraosseous hemangioma with ABC-like changes. There has been no case report of intraosseous hemangioma in the hyoid bone. This case showed a spectral pattern of the ABC-like changes developing from the underlying bone tumor as a secondary change. ABC-like changes in bone tumors can mislead the diagnosis. Careful examination of the tumor is essential for the correct diagnosis of ABC or ABC-like changes.

Surgery for a symptomatic massive liver haemangioma.

Liver haemangiomas are the most common benign hepatic tumours, but secondary portal hypertension resulting from haemangiomas is exceedingly uncommon. We present a case of a man in his 50s who presented with a progressively enlarging mass in the right upper abdomen. CT of the liver revealed a large hypodense lesion involving the right lobe, with two smaller lesions in the left lobe. The portal vein was compressed by the tumour, causing portal hypertension. The patient underwent right hepatectomy. Postoperatively, the patient had an uneventful course, and a 3-month follow-up demonstrated resolution of the oesophageal varices, portal gastropathy, with hypertrophy of the left lobe. This case report highlights the successful surgical management of a rare massive hepatic haemangioma causing portal hypertension with surgical resection, emphasising the potential benefits of surgical intervention with minimal complications.
