Blue rubber bleb nevus syndrome as a cause of lower digestive bleeding

Blue rubber bleb nevus syndrome with massive gastrointestinal hemorrhage and pulmonary embolism: A case report

BACKGROUND

Blue rubber bleb nevus syndrome is a rare disease. The main cause of death in these patients is massive hemorr-hage of the digestive tract. When the hemorrhage is combined with pulmonary embolism, greater treatment challenges are posed.

CASE SUMMARY

A man was admitted to the hospital because of repeated black stools for more than 20 years and aggravation for 10 d. A diagnosis of sigmoid colon and rectal blue rubber bleb nevus syndrome with massive hemorrhage due to nevus rupture was made. Conservative treatment including medical hemostasis and blood transfusion had a poor effect. Hemorrhagic shock occurred. The sigmoid colon and rectum were totally resected in the emergency setting. After operation, acute pulmonary embolism developed. Low molecular weight heparin anticoagulation and subsequent oral warfarin anticoagulation were given. The patient's bleeding stopped, and pulmonary thrombosis disappeared. He has recovered well and is now alive.

CONCLUSION

In patients with preoperative massive hemorrhage due to blue rubber bleb nevus syndrome, acute pulmonary embolism may occur after operation, and the risk of intravenous thrombolytic hemorrhage is very high. In such cases, low-molecular-weight heparin + warfarin oral bridging treatment can be chosen. During the treatment, the coagulation function should be closely monitored to avoid massive hemorrhage. The dosage should be adjusted according to the prothrombin time and international normalized ratio (INR) to maintain the INR between 2-3, and the patients should be subject to whole process management. D-dimer and INR should be reviewed regularly to monitor the complications of bleeding, and patients can benefit when they are treated properly.

Blue rubber bleb nevus syndrome complicated with disseminated intravascular coagulation and intestinal obstruction: A case report

BACKGROUND

Blue rubber bleb nevus syndrome is a rare vascular malformation syndrome with unclear etiopathogenesis and noncurative treatments. It is characterized by multiple vascular malformations of the skin, gastrointestinal tract, and other visceral organs. The most common symptoms are intermittent gastrointestinal bleeding and secondary iron deficiency anemia, thus requiring repeated blood transfusions and hospitalizations. It is easily missed and misdiagnosed, and there is no specific treatment.

CASE SUMMARY

We report a case of blue rubber bleb nevus syndrome combined with disseminated intravascular coagulation and efficacy of treatment with argon plasma coagulation under enteroscopy and sirolimus. A 56-year-old female patient was admitted to the hospital with 3-year history of fatigue and dizziness that had aggravated over the past 10 d with melena. The patient had a history of repeated melena and multiple venous hemangiomas from childhood. After treatment with argon plasma coagulation combined with sirolimus for nearly 8 wk, the patient’s serum hemoglobin increased to 100 g/L. At the 12-mo follow-up, the patient was well with stable hemoglobin (102 g/L) and no recurrent intestinal bleeding.

CONCLUSION

Argon plasma coagulation and sirolimus may be an efficacious and safe treatment for blue rubber bleb nevus syndrome, which currently has no recommended treatments.

Blue rubber bleb nevus syndrome: a single-center case series in 12 years

BACKGROUND

Blue rubber bleb nevus syndrome is a rare congenital disease characterized by multiple venous malformations in skin and gastrointestinal tract, not all patients have typical cutaneous lesions, refractory anemia may be the only clinical symptom, it is easy to miss diagnosis.

METHODS

A retrospective single center study was conducted on 8 patients with blue rubber bleb nevus syndrome from 2009 to 2021. Data were analyzed including clinical feature, diagnostic workup and results, gene detection, treatment and follow-up.

RESULTS

Five children (62.5%) developed the disease in infancy, which initial symptoms were all cutaneous venous malformations. All children had chronic refractory anemia and gastrointestinal bleeding. Cutaneous lesions were observed in 87.5%, 1 child had multiorgan involvement. Gastrointestinal venous malformations were observed in 100%, lesions were more common in small intestine than in stomach or colon. No somatic mutation in TEK was found in our children. Diagnostic interval was on average 4.7 years. Eighty-seven-point-five percent children received at least one endoscopic or surgical intervention, however, those methods could not eradicate all the lesions and prevent relapse. Two children treated with sirolimus for more than 8 years, only 1 have satisfactory therapeutic effect. Besides, I child has growth retardation and emotional problems during follow-up.

CONCLUSIONS

Blue rubber bleb nevus syndrome needs to be considered when find bluish nodular cutaneous lesions, chronic anemia or gastrointestinal bleeding of unknown origin. Capsule endoscopy is the most sensitive in diagnosing of this disease. Oral sirolimus at a relatively low dosage is effective, further comprehensively studies are required to evaluation of its efficacy, safety and the optimal dosage about the children.

Blue Rubber Bleb Nevus Syndrome because of 12 Years of Iron Deficiency Anemia in a Patient by Double Balloon Enteroscopy; A Case Report and Review of Literature

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder comprised of venous malformation mostly involving the skin and gastrointestinal (GI) tract but can also involve other visceral organs. The most predominant site of GI tract involvement is the small bowel. In patients with GI lesions, treatment depends on the severity of bleeding, and extent of involvement. Conservative therapy with iron supplementation and blood transfusion is appropriate in cases with mild bleeding but in severe cases endoscopic and surgical interventions would be beneficial. Also, medical therapy with sirolimus significantly reduces bleeding. A 20-year-old woman was referred to our hospital after transfusion of six units of packed cell because of several episodes of lower GI bleeding within the past three months in the form of melena and a single episode of hematochezia. Her last hemoglobin level before admission was 10mg/dl. She underwent various unsuccessful investigations since she was eight years old to find the origin of refractory iron deficiency anemia. In upper endoscopy, five bleeding polypoid lesions were discovered in the jejunum. Lesions were excised by snare polypectomy. Over a six-month follow-up period, no signs of lower GI bleeding were noted and the patient had a normal hemoglobin level.

Atypical Blue Rubber Bleb Nevus in an African-American Male

Blue Rubber Bleb Nevus Syndrome (BRBNS), also known as Bean Syndrome, is a rare condition characterized by vascular ectasias that typically present systemically. Most diagnoses are made in early childhood due to cutaneous lesions in Caucasians with familial inheritance. Treatment is usually patient centered due to the wide variance in clinical presentation of the disease. Here, we present a case of BRBNS in a 65-year-old African-American patient with episodic gastrointestinal (GI) bleeding with no previous history. This case emphasizes the need for a higher clinical suspicion of the disease in patients with recurrent GI bleeding.

[Clinical effect of sirolimus in treatment of blue rubber bleb nevus syndrome in children: a report of 2 cases and literature review]

To study the clinical effect of oral sirolimus in the treatment of children with blue rubber bleb nevus syndrome (BRBNS) in the gastrointestinal tract, a retrospective analysis was performed on the clinical data and follow-up results of two children with BRBNS treated by sirolimus. The two children with BRBNS had gastrointestinal bleeding and anemia and were treated with sirolimus at a dose of 1 mg/day as part of treatment. The plasma concentration of the drug was maintained between 2.5-12.0 ng/mL. The children showed disappearance of gastrointestinal bleeding and improvements in anemia and coagulation function, and blood transfusion could be stopped during treatment, with no obvious adverse drug reactions. PubMed, Wanfang Data, and CNKI were searched for related articles on sirolimus in the treatment of BRBNS. A total of 26 cases of children with BRBNS, aged 0-18 years, were obtained. With the addition of the 2 cases in this study, sirolimus treatment achieved a satisfactory clinical effect in all 28 cases. Sirolimus may be effective and safe in the treatment of children with BRBNS, and further prospective studies are needed to evaluate the long-term efficacy of this drug.

Syndromе associated with multiple venous malformations (Bean syndrome)

Blue rubber bleb nevus syndrome (BRBNS) also called Bean's syndrome is a rare disorder characterized by mucocutaneous angiomatose multiple cutaneous venous malformations. Pathogenesis of the BRBNS is caused by the somatic mutations in angiopoietin receptor gene TEK. These mutations cause ligand-independent activation of the tyrosine kinase receptor and the PI3K / AKT pathway and involve the mTOR in the pathological process in a specific way. There are no universally effective methods for treating systemic forms of vascular malformations currently. However, recent numerous reports have shown the advantages of rapamycin, an mTOR inhibitor, as a well-tolerated and effective therapy in patients with vascular abnormalities, in particular with diffuse angiomatose. This article presents a clinical case of a 5-years old patient with a diagnosis of iron deficiency anemia, who has been treated for a long time and received iron supplements therapy without achieving any effect. The diagnosis of Bean's syndrome was established after 5 years from the first clinical manifestation and based on clinical, laboratory and instrumental methods. The cause of iron deficiency anemia was established. It was repeated chronic bleedings from multiple sites of the gastrointestinal mucosa vessels. Prescribed rapamycin therapy allowed to contain gastrointestinal bleeding, to reduce the size of vascular lesions and to prevent the formation of new ones. Parents gave their consent to use information about the child in the article.

Blue Rubber Bleb Nevus Syndrome with Long-Term Follow-Up: A Case Report and Review of the Literature

Blue rubber bleb nevus syndrome (BRBNS) is a rare disease in which venous malformations (VMs) involve any body organ, most commonly the skin and the gastrointestinal (GI) tract. Treatment of BRBNS aims at preserving the GI tract as much as possible. Although there are several dozen case reports about BRBNS that describe short-term clinical courses, a few provide an account of long-term clinical course. Here, we report a case of BRBNS in a girl that required multiple abdominal surgeries due to the GI VMs and a recurrence at an interval of 14 years. The preferred approach for gastrointestinal VMs involves the complete resection of all lesions without residual VMs. It is important to bear in mind the possibility of delayed recurrence of GI VMs after surgical or endoscopic treatment.

A 10-year delayed diagnosis of blue rubber bleb nevus syndrome characterized by refractory iron-deficiency anemia: A case report and literature review

RATIONALE

Blue rubber bleb nevus syndrome (BRBNS) is a rare vascular disorder consisting of multifocal venous malformations. Delayed diagnosis or misdiagnosis frequently occurs in patients without typical cutaneous lesions or gastrointestinal bleeding symptoms. This article reports a 10-year case of delayed diagnosis of BRBNS detected by capsule endoscopy.

PATIENT CONCERNS AND DIAGNOSIS

A 15-year-old girl presented with refractory iron-deficiency anemia (IDA) for 10 years, without any hemorrhagic signs or noticeable cutaneous lesions, which led to her obvious physical growth retardation. Capsule endoscopic examination revealed dozens of vascular blebs distributed from the jejunum to the ileum and a site of active bleeding. Hence, she was diagnosed with BRBNS.

INTERVENTIONS

Laparotomy was performed with resection of the small bowel lesions, and iron supplementation was prescribed for 3 months. Postoperatively, the patient had an uncomplicated course.

OUTCOMES

On follow-up after 3 years, IDA in this patient was cured and she did not require further blood transfusion and showed excellent vigor.

LESSONS

A high index of suspicion for BRBNS and adequate endoscopy examination will help to identify the origin of refractory IDA in older children, particularly in patients with vascular lesions of the skin.

Blue rubber bleb nevus syndrome: our experience and new endoscopic management

The aim of our study is to enhance the awareness of blue rubber bleb nevus syndrome (BRBNS) through the patients in our hospital and introduced a new measure of endoscopic intervention.A retrospective review of 5 patients, who were diagnosed as BRBNS in our hospital from January 2013 to January 2017, was conducted. Data were collected with regard to demographics, clinical presentation, endoscopic and imaging findings, management, and follow-up data.In total of 5 patients, the mean age was 28.8 years, range 16 to 44 years (male/female, 1/4) with the average initial age of onset 15.4 years. No family history was identified in our group. Physical examination showed multiple cutaneous lesions in 2 patients (40%, 2/5). All the 5 patients had gastrointestinal tract vascular malformations; stomach involved in 2 cases, large intestine in 2 cases, and small intestine involved in 3 cases. Lesions in the visceral organs and tissue were found in 1 patient. Gastrointestinal bleeding was its main symptom (3/5, 60%). Laboratory investigations revealed anemia in 4 patients and abnormality of coagulopathy in 2 patients with severe anemia. Conservative approach was recommended in 3 cases that included iron supplementation, drug hemostasis, and/or blood transfusion. An innovatively therapeutic approach with endoscopic submucosal dissection (ESD) procedure was used successfully in 1 patient with 2 polypoid BRBNS lesions in rectum.BRBNS is a very rare vascular malformation syndrome with unclear etiopathogenesis and noncurative treatments. ESD procedure was a feasible approach to remove the partial gastrointestinal lesions.

Postoperative disseminated intravascular coagulation in a pregnant patient with Blue Rubber Bleb Nevus Syndrome presenting with acute intestinal obstruction: Case report and literature review

BACKGROUND

Blue Rubber Bleb Nevus Syndrome (BRBNS) is a rare condition which usually manifests as multiple hemangioma-like skin and gastrointestinal lesions. The latter often present with chronic bleeding. There is no consensus regarding the optimal management of such patients. Although rare, complications such as intestinal intussusception might occur, demanding surgical treatment. Postoperative complications such as coagulation disorders can increase morbidity and should be timely addressed. This is the first report of a life-threatening postoperative disseminated intravascular coagulation in such patients. The main objectives of this case report are to present diagnostic and treatment features of this condition and, more importantly, address the optimal management of postoperative disseminated intravascular coagulation.

CASE PRESENTATION

Twenty-five year-old female pregnant patient presents to the emergency department with colicky pain and oligohydramnios. After C-section, persistent symptoms and further investigation led to the diagnosis of intestinal intussusception. After surgical management she showed clinical and laboratory signs of disseminated intravascular coagulation (DIVC), which was corrected with transfusional therapy and intraperitoneal clot evacuation. After optimal management, she was discharged home. Sirolimus was initiated further improving her condition.

CONCLUSION

This rare presentation of acute intestinal intussusception in a patient with Blue Rubber Bleb Nevus Syndrome was further complicated with postoperative coagulation disorder. Prompt surgical evaluation is essential especially when complications are suspected. Operative treatment might be necessary in the emergent setting. Close monitoring of infectious and coagulation parameters is essential in the postoperative period, and aggressive treatment should be timely initiated when disseminated intravascular coagulation is suspected.

Blue rubber bleb naevus syndrome: a rare cause of chronic occult blood loss and iron deficiency anaemia

Blue rubber bleb naevus syndrome (BRBNS) is a rare vascular disorder with malformed veins, or blebs, appearing in the skin or internal organs. Gastrointestinal tract involvement is the most common feature and often subject to bleeding, potentially resulting in chronic occult blood loss and iron deficiency anaemia. We present the case of a 10-year-old boy with venous malformations on the feet and severe anaemia. Although massive sudden haemorrhage rarely occurs, awareness of the illness is necessary to prevent complications.
