“…One of our patients also had polyarteritis nodosa (PAN) and was being anticoagulated because of recent bowel ischaemia related to this condition. Retroperitoneal haemorrhage and its successful treatment with embolization has been previously reported with PAN 26,27 . Our patient showed typical angiographic signs of PAN in the renal artery and it is possible that underlying vascular abnormality contributed to his spontaneous lumbar arterial bleed.…”

Four cases of extraperitoneal haemorrhage occurring in the setting of anticoagulation or coagulopathy are presented. Treatment of this condition has traditionally consisted of reversal of anticoagulation and supportive therapy. Diagnosis was made on contrast-enhanced computed tomography. The finding of active contrast extravasation was found to be a factor predictive of failure of conservative therapy and, therefore, an indication for angiography and embolization. In all four cases presented in the present paper, the bleeding vessel(s) were identified and significant active bleeding arrested by transcatheter embolization.

“…Currently, transcatheter selective renal artery embolization is typically performed instead of nephrectomy. With this therapy, favorable outcomes have been reported, regardless of embolic material, unilateral, or bilateral hematoma [6,[12][13][14][15]. The procedure-related mortality of selective embolization is 3.6% [16].…”

Polyarteritis nodosa with perirenal hematoma due to the rupture of a renal artery aneurysm

et al. 2020

We present the case of a 67-year-old man in good health with perirenal hematoma due to a ruptured arterial aneurysm in the kidney. The patient developed weight loss, muscle weakness, multiple mononeuropathy, hypertension, anemia, renal insufficiency, and multiple lacuna infarctions about a month ago. He was admitted to the hospital due to worsening of his symptom. After admission, severe right-flank pain suddenly occurred; he was then transferred to our hospital. Renal angiography revealed bilateral multiple microaneurysms, and the patient was diagnosed with polyarteritis nodosa based on the clinical, radiographic, and histological findings. We performed selective coil embolization to the ruptured aneurysm and administered oral prednisolone along with intravenous methylprednisolone pulse therapy. Cyclophosphamide pulse therapy was also given. The treatment improved clinical and laboratory findings and achieved clinical remission. Selective coil embolization to the bleeding aneurysm of polyarteritis nodosa was minimally invasive and promptly effective. Immunosuppressants proved useful in the regulation of disease activity and the aneurysm.

“…Hepatic arterial embolization with or without selective hepatic artery infusion of chemotherapy is frequently applied as a palliative technique in patients with symptomatic hepatic metastases who are not candidates for surgical resection. The response rates associated with embolization or chemoembolization, as measured either by decrease in hormonal secretion or by radiographic regression, are generally greater than 50 percent [16]. However, the duration of response can be brief, ranging from 4 to 24 months in uncontrolled series [17, 18].…”

Introduction. Gastrinoma should be suspected when the peptic ulcer(s) is postbulbar, multiple, refractory, or recurrent, or ulcer is associated with nephrolithiasis, hypocalcaemia, or erosive esophagitis. The majority of gastrinomas are malignant. Case Presentation. The patient is a 41-year-old Iranian man who has been in good health until 36 months ago when duodenal perforation and two bouts of upper GI bleeding (GIB), each two months apart occurred. He also mentioned mild watery diarrhoea and decreased appetite. Serum gastrin level was elevated. Abdominal CT scan revealed pancreatic mass and three enhancing hepatic masses. CT-guided pancreatic biopsy revealed monotonous cells. Chemoembolization of hepatic metastases was done. New ct images 6 months later showed nearly total regressed hepatic and pancreatic lesions. Conclusion. Beside previously defined situations that take gastrinoma into account as the etiology of PUD, accumulation of PUD complications is highly suggestive of Zollinger-Ellisone syndrome (ZES). Regression of pancreatic primary after chemoembolization of hepatic metastases is unexplainable at the present time.
