Spontaneous Haemorrhage

Introduction Sporadic renal angiomyolipomas, although benign in natural can cause life-threatening spontaneous haemorrhage. Surveillance of smaller lesions is recommended but there is no guidance on the surveillance interval or modality. Our aim was to study our sporadic angiomyolipoma population to determine the growth rate, factors that were associated with a higher growth rate and design a surveillance programme. Materials and methods All sporadic renal angiomyolipomas diagnosed between September 2009 and March 2015 were included. Patients with a diagnosis of tuberous sclerosis were excluded. Results A total of 217 sporadic renal angiomyolipomas were diagnosed. The median follow-up was 24 months (range 10–118 months). The median size at diagnosis was 9.00 mm with a mean growth rate of 0.13 mm/year (standard deviation 0.88). One hundred and fifty angiomyolipomas (69%) were shown to have negative or zero growth. In the remaining 67, 59 had a growth rate of less than 2.00 mm/year. Size of angiomyolipoma, tumour burden and age were not associated with a higher growth rate on multivariate analysis. Conclusion The majority of sporadic angiomyolipomas are small and do not grow. Our practice is to perform surveillance for those greater than 20 mm, with five-yearly ultrasound scans for 21–29 mm, and two-yearly surveillance for 30–39 mm tumours.

Abstract Background The life-threatening haemorrhagic complications of pulmonary arteriovenous malformations (PAVMs) are extremely rare, and only described in isolated cases. This study was designed to comprehensively investigate management of ruptured PAVMs. Methods We retrospectively assessed clinical and imaging data of ruptured PAVMs to summarize incidence, clinical characteristics, and outcomes following embolisation between January 2008 and January 2021. Results Eighteen of 406 (4.4%) patients with PAVMs developed haemorrhagic complications. Twelve of 18 patients were clinically diagnosed with hereditary haemorrhagic telangiectasia (HHT). Haemorrhagic complications occurred with no clear trigger in all cases. Eight of 18 patients (44.4%) were initially misdiagnosed or had undergone early ineffective treatment. 28 lesions were detected, with 89.3% of them located in peripheral lung. Computed tomography angiography (CTA) showed indirect signs to indicate ruptured PAVMs in all cases. Lower haemoglobin concentrations were associated with the diameter of afferent arteries in the ruptured lesions. Successful embolotherapy was achieved in all cases. After embolotherapy, arterial oxygen saturation improved and bleeding was controlled (P < 0.05). The mean follow-up time was 3.2 ± 2.5 years (range, 7 months to 10 years). Conclusions Life threatening haemorrhagic complications of PAVMs are rare, they usually occur without a trigger and can be easily misdiagnosed. HHT and larger size of afferent arteries are major risk factors of these complications. CTA is a useful tool for diagnosis and therapeutic guidance for ruptured PAVMs. Embolotherapy is an effective therapy for this life-threatening complication.

Abstract Background Angiomyolipomas are rare mesenchymal tumours arising from the perivascular epithelioid cells consisting of variable amounts of adipose, thick-walled blood vessels and smooth muscle cells. These benign tumours commonly occur in the kidney with only a few case reports of adrenal angiomyolipomas which have the potential to reach a large size and haemorrhage. Case presentation A 45-year-old lady presented with a 3-week history of right loin pain, nausea and vomiting. A CT scan revealed a right adrenal angiomyolipoma measuring 6.3 × 6.8 cm with associated haemorrhage. The lesion was successfully treated with right open adrenalectomy, and histology confirmed the diagnosis of adrenal angiomyolipoma. The patient remained well with no evidence of recurrence at the 36-month follow-up. Conclusion Adrenal angiomyolipomas are rare benign tumours that have the ability to reach a large size and potential to bleed. Here, we report the second case of spontaneous haemorrhage in an adrenal angiomyolipoma, which was successfully treated with open adrenalectomy.

We reported a rare case of spontaneous frank rupture of a small (4 mm) penetrating aortic ulcer in the ascending aorta resulted in catastrophic bleeding. The ulcer only created a pinhole wound in the adventitia without saccular aneurysms, intramural hematomas, or aortic dissections. Notably, the wound could be directly closed because the aortic wall was intact only 5 mm away from the bleeding site. The postoperative course was uneventful, and the patient was discharged on the 11th postoperative day. After 8 months, follow-up computed tomography showed no abnormality of the aortic wall at the repair site.

Abstract Background Pregnancy is a known risk factor for pituitary apoplexy, which is life threatening for both mother and child. However, very few clinical interventions have been proposed for managing pituitary apoplexy in pregnancy. Case presentation We describe the management of three cases of pituitary apoplexy during pregnancy and review available literature. Presenting symptoms in our case series were headache and/or visual disturbances, and the etiology in all cases was hemorrhage. Conservative therapy was followed until 34 weeks of gestation, after which babies were delivered by cesarean section with prophylactic bolus hydrocortisone supplementation. Tumor removal was only electively performed after delivery using the transsphenoidal approach. All three patients and their babies had a good clinical course, and postoperative pathological evaluation revealed that all tumors were functional and that they secreted prolactin. Conclusions Although the mechanism of pituitary apoplexy occurrence remains unknown, the most important treatment strategy for pituitary apoplexy in pregnancy remains adequate hydrocortisone supplementation and frequent hormonal investigation. Radiological follow-up should be performed only if clinical symptoms deteriorate, and optimal timing for surgical resection should be discussed by a multidisciplinary team that includes obstetricians and neonatologists.

Abstract Background While the perforation of the atrial wall and aortic sinus after closure of an atrial septal defect (ASD) is rare, it’s life-threatening, with rapid progress and high mortality. To the best of our knowledge, 21 similar cases have been reported since 1976. Case presentation We report a 16-year-old male whose atrial septal defect (ASD) was closed using a 12-mm Amplatzer septal occluder (ASO). Atrial wall and aortic sinus perforation occurred 3 months after transcatheter closure, and the patient was discharged after emergency operation. He was discharged on the 12th postoperative day in good overall condition. Conclusions With this case report, we want to illustrate that although percutaneous closure of ASD is regarded as a routine procedure, we should not forget the potentially lethal complications, especially cardiac erosion. Therefore, we should carefully evaluate the risk of erosion before surgery, and careful lifelong follow-up is needed.

Well-differentiated papillary mesothelioma (WDPM) is an uncommon mesothelial tumor. The lesions may be single or multiple and usually behave in a benign or indolent fashion, sometimes persisting for many years. In the present case, a 37-year-old woman had experienced primary infertility for 12 years, and a diagnostic laparoscopy was performed. Approximately 200 mL of dark red, free fluid in the pelvis and more than 10 yellow-white nodules on the surface of the right round ligament, sacrum ligament, right fallopian tube, and both sides of the uterus were found. A lesionectomy was performed and immunohistochemical markers indicated WDPM with adenomatoid tumor. The patient was monitored by computed tomography and serum CA125 (cancer antigen 125) levels for 49 months with no recurrence. WDPM and adenomatoid tumor are both benign tumors of mesothelial origin. Because of the lack of effective radical treatment, regular follow-up is sufficient. However, the effects of estrogen and progesterone on WDPM and adenomatoid tumors during ovulation or pregnancy remains unclear. Although WDPM is not life threatening, a strategy to fulfill the fertility requirements of women with this condition is a new challenge for infertility doctors.

Abstract Background Endoscopic cyanoacrylate (glue) injection of fundal varices may result in life-threatening embolic adverse events through spontaneous gastrorenal shunts (GRSs). Balloon-occluded retrograde transvenous occlusion (BRTOcc) of GRSs during cyanoacrylate injection may prevent serious systemic glue embolization through the shunt. This study aimed to evaluate the efficacy and safety of a combined endoscopic–interventional radiologic (BRTOcc) approach for the treatment of bleeding fundal varices. Methods We retrospectively analysed the data of patients who underwent the combined procedure for acutely bleeding fundal varices between January 2010 and April 2018. Data were extracted for patient demographics, clinical and endoscopic findings, technical details, and adverse events of the endoscopic–BRTOcc approach and patient outcomes. Results We identified 30 patients (13 [43.3%] women; median age 58 [range, 25–92] years) with gastroesophageal varices type 2 (53.3%, 16/30) and isolated gastric varices type 1 (46.7%, 14/30) per Sarin classification, and median clinical and endoscopic follow-up of 151 (range, 4–2,513) days and 98 (range, 3–2,373) days, respectively. The median volume of octyl-cyanoacrylate: Lipiodol injected was 7 (range, 4–22) mL. Procedure-related adverse events occurred in three (10.0%) patients, including transient fever, non-life-threatening pulmonary glue embolism, and an injection-site ulcer bleed. Complete gastric variceal obturation was achieved in 18 of 21 patients (85.7%) at endoscopic follow-up. Delayed variceal rebleeding was confirmed in one patient (3.3%) and suspected in two patients (6.7%). Although no procedure-related deaths occurred, the overall mortality rate was 46.7%, primarily from liver-disease progression and co-morbidities. Conclusion The combined endoscopic–BRTOcc procedure is a relatively safe and effective technique for bleeding fundal varices, with a high rate of variceal obturation and a low rate of serious adverse events.

Ultrasound guided aspiration biopsy of renal mass lesions was performed in 56 patients in whom renal cell carcinoma could not be excluded due to equivocal imaging results. Cytology showed non-malignant mesenchymal cells consistent with angiomyolipoma in 12 patients. In 5 of these patients the diagnosis was ensured by open biopsy. No nephrectomy was performed. In 6 of the 7 patients not operated upon the tumours remained unchanged with no evidence of malignancy during a 3–36 months' follow-up period. Aspiration biopsy is an easy and safe method for diagnosing renal angiomyolipoma in cases where computed tomography is not diagnostic for this disease.

Toxoplasmosis is generally asymptomatic in immunocompetent individuals, but it can be life-threatening in immunocompromised patients. We present a case of a 62-year-old man with clinical features of acute appendicitis. Histology showed a transmural infiltrate of eosinophils. In addition, there were reactive lymphoid follicles with histiocytes in the submucosa and tachyzoites in the muscularis propria. Immunohistochemistry confirmed the diagnosis of toxoplasma appendicitis. Serological evaluation yielded negative results. Retrospective review of the history revealed that the patient was on long-term immunosuppressive therapy with methotrexate. The patient was treated with sulfamethoxazole-trimethoprim and is asymptomatic at 7-month follow-up. Toxoplasma appendicitis must be considered in the differential diagnosis of appendicitis in immunosuppressed patients.
