OBJECTIVETo investigate the characteristics,diagnosis and therapy of post-biopsy renal artery pseudoaneurysm in children and to study the clinical value of arterial embolization for traumatic renal hemorrhage when conservative treatment failed.

METHODData were compiled from medical records of a child in whom renal artery pseudoaneurysm occurred after biopsy in the Provincial Hospital Affiliated to Shandong University , and the related literature was reviewed to analyze the diagnosis and treatment of such pseudoaneurysm.

RESULTA 13-year-old boy had gross hematuria, aggravated dysuria and decreased hemoglobin 10 days after percutaneous renal biopsy. Hb decreased from 110 g/L on the first day after admission to 92 g/L on the 4th day, 83 g/L on the 7th day and the minimum to 74 g/L at the 8th day after admission. Ultrasound showed solid echogenic mass in the right renal pelvis as well as the bladder. Color Doppler ultrasound shows the red and blue rotation of blood flow in the polar capsule under the right kidney. Contrast-enhanced CT in the arterial phase showed a 0.5 cm sized renal mass with a strongly enhanced dot in the lower pole of the right kidney, suggesting a renal artery pseudoaneurysm. Haemostatic, supplement of red blood cells and blood volume and other integrative treatment of hematuria were applied for seven days, but his gross hematuria continued to be worsened. He was diagnosed as pseudoaneurysm by digital subtraction angiography (DSA) on the 19th day after renal biopsy. Superselective renal artery embolization using micro-coils and gelatin sponge particles was performed, and the blood clots were cleaned under cystoscope. Macro-haematuria and dysuria disappeared after the interventional treatment. Retrieval of reports on post-biopsy renal artery pseudoaneurysm in children by using "pseudoaneurysm, child" as the search term showed report of one case from the Chinese CNKI database and 3 cases from the PubMed database. The underlying disease was Henoch-Schonlein purpura nephritis in 3 cases and Sneedon syndrome in 1 case; clinical manifestation of gross haematuria was present in 4 cases, lumbago or pain at the site of the puncture in 2 cases, dysuria in 1 case, and fever in 2 cases.

CONCLUSIONThe post-biopsy renal artery pseudoaneurysm in children is often manifested as gross hematuria, lumbago, pain at the site of the puncture, fever and dysuria, DSA can be used for definite diagnosis and the interventional treatment is effective.

Neurofibromatosis type 1 (NF-1) is an autosomal dominant disorder. Pseudoaneurysms formation and rupture is an unusual complication of neurofibromatosis. To date, pseudoaneurysm of the internal pudendal artery associated with NF-1 has not been reported. In this article, we present a 62-yr-old man with NF-1 suffering from spontaneous hematoma of the perinea and scrotum. A digital substraction angiography disclosed a ruptured pseudoaneurysm of the right internal pudendal artery, which was successfully managed with transcatheter embolization.

Necrotizing aortitis is a rare and life-threatening complication of local or generalized bacterial infections and most commonly affects the abdominal aorta. We described a case of a 79-year-old man with an acupuncture-induced bacterial aortitis associated with pseudoaneurysm formation causing near rupture. The patient underwent emergent explolapartomy, resection of the infected aorta, wide debridement of surrounding infected tissues, and extra-anatomic axillary to bifemoral graft bypass. The microbiologic examination revealed Escherichia coli and methicillin resistant Staphylococcus aureus (MRSA). Necrotizing aortitis is very serious and fatal disease, careful history taking as well as rapid diagnosis and urgent treatment are of critical importance.

OBJECTIVETo evaluate the long-term effect of endovascular occlusion with microcoils on traumatic pseudoaneurysms (TPAs) in the common carotid artery in rabbits.

METHODSTPAs in the right common carotid artery were surgically made in 16 rabbits. At 3-4 weeks after operation, the survived 12 models were randomly divided into a control group (n=3) with no treatment and an experimental group (n=9), in which TPAs were intraluminally embolized with microcoils and corresponding therapy was given. Three months after embolization, the TPAs were examined with digital subtraction angiography and pathology.

RESULTSThe 3 rabbits in the control group all died of rupture of TPA. Among the 9 TPAs occluded with microcoils, 4 were completely occluded, 4 were partially occluded, and 1 was excluded due to the microcoils migrating into the parent artery. Three months after embolization, the 4 TPAs which were completely occluded remained obliterated as determined by digital subtraction angiographic findings. The parent artery remained unobstructed and the structure of the TPAs were replaced by a mass of scar tissues. The 4 TPAs which were partially occluded remained unruptured and the microcoils were compressed.

CONCLUSIONSThe lumen in TPA can be completely occluded by microcoils and the parent artery is unblocked. Partial occlusion of the lumen can also prevent the rupture of TPA.

The increased use of interventional procedures and laparoscopic cholecystectomy in the management of hepatobiliary disorders is associated with an increased incidence of hemobilia and hepatic artery aneurysm. Here we report a case of hepatic artery pseudoaneurysm associated with a plastic biliary stent. Multiple factors were involved in the formation of the hepatic artery aneurysm (HAA) and it was successfully treated by embolization.
