1/44. Embolization of iatrogenic venous pseudoaneurysm.

    A case is described where a patient on long-term anticoagulation developed a venous pseudoaneurysm in the antecubital fossa following venepuncture. This venous pseudoaneurysm was successfully treated with coil embolization.

2/44. Pitfall: a pseudo tumor within the left liver lobe presenting with abdominal pain, jaundice and severe weight loss.

    A 51 year old male patient with a history of chronic alcohol consumption and recurrent pancreatitis was referred to our hospital with jaundice, epigastric pain, severe diarrhoea and weight loss of 28 kg within the last 12 months. A CT scan of the abdomen 4 months before admission had shown a pancreatitis with free fluid around the corpus and tail of the pancreas as well as dilated intrahepatic bile ducts and a cavernous transformation of the portal vein. Moreover, a tumor (3.5 x 3.0 x 3.6 cm) with irregular contrast enhancement was seen within the left liver lobe. The patient was referred to us for further evaluation and treatment. The initial B-Mode sonogram revealed a bull's eye like well defined lesion (8.1 x 7.5 x 7.0 cm) within the left liver lobe, consistent with a tumour or abscess. Prior to a diagnostic needle biopsy a PTCD was performed in this case presenting with dilated intrahepatic bile ducts and having a history of Billroth II operation. An additional colour coded Duplex Doppler ultrasonography demonstrated a visceral artery aneurysm and prevented us from performing the diagnostic puncture. The aneurysm was assumed to originate from a variant or a branch of the left hepatic artery. angiography revealed a pseudoaneurysm of the pancreaticoduodenal artery and coil embolization was performed because of the increasing size and the risk of a bleeding complication. Postinterventional colour duplex ultrasound measurement showed no blood flow within the aneurysm. Retrospectively, the pseudoaneurysm must have led to a compression of the common bile duct, since the patient did not develop cholestasis after embolization and removal of the PTCD. Thus, a pseudoaneurysm of the pancreaticoduodenal artery must be included in the differential diagnosis of liver tumours in patients with chronic pancreatitis, despite its unusual localization near the liver. Therefore, we suggest that colour coded ultrasonography should be applied to any unclear, bull's eye like lesion, even though this method alone cannot exactly determine the origin of the pseudoaneurysm. Interventional angiography remains the gold standard for the diagnosis and therapy of visceral artery aneurysm.

3/44. Transverse cervical artery pseudoaneurysm: a rare complication of internal jugular vein cannulation.

    Internal jugular vein cannulation has become the preferred approach for temporary hemodialysis catheter placement following reports of an increased incidence of subclavian vein stenosis due to subclavian vein catheterization. Internal jugular vein catheterization is associated with a high rate of successful catheter placement. However, significant complications such as internal carotid artery (ICA) puncture, pneumothorax, vessel erosion, thrombosis, airway obstruction and infection can occur. The most common complication is ICA puncture. More recently a few cases of thyrocervical trunk pseudoaneurysm and fistula following internal jugular vein and subclavian vein catheterization attempts have been reported. patients with renal failure who are on hemodialysis may have to undergo multiple catheter placements and vascular access interventions. This, along with their comorbid conditions, increases the risk of such complications. Here we report a patient on hemodialysis who developed transverse cervical artery pseudoaneurysm following an attempted right internal jugular vein catheterization. We report this case because of its rarity, to raise awareness of such a complication and to discuss different treatment options, in particular endovascular coil occlusion. A review of relevant literature is also presented.

4/44. Treatment of a false aneurysm of an intercostal artery using a covered intracoronary stent-graft and a radial artery puncture.

    This case report documents the successful treatment of a false aneurysm of the left internal mammary artery with a covered coronary artery stent. The advantages and disadvantages of this novel method of treatment are discussed, together with a review of alternative methods of treatment of false aneurysms.

5/44. Percutaneous thrombin injection of carotid artery pseudoaneurysm.

    PURPOSE: To report the successful treatment of a carotid artery pseudoaneurysm by percutaneous thrombin injection. CASE REPORT: A 71-year-old man with end-stage renal failure presented with acute left ventricular failure. The right common carotid artery (CCA) was punctured during attempted jugular line insertion, and he developed a large pseudoaneurysm connected to the CCA by a long, narrow neck. Ultrasound-guided compression was unsuccessful, so another technique was attempted. An occlusion balloon was inflated in the CCA at the neck of the aneurysm to avoid distal embolization, and 250 units of human thrombin were injected into the sac percutaneously; thrombosis was instantaneous. There were no procedural complications, and repeat ultrasound at 3 months showed resolution of the hematoma and no residual pseudoaneurysm. There were no neurological complications. CONCLUSIONS: Percutaneous thrombin injection may be a new and successful method of treating carotid artery pseudoaneurysms.

6/44. Pseudoaneurysm of the popliteal artery: a rare sequela of acupuncture.

    Acupuncture is an ancient Chinese treatment that has proved effective in relieving pain of various origins. Pseudoaneurysm resulting from acupuncture is an extremely rare event. Only 4 patients treated surgically for such a condition have previously been reported in the world medical literature. We present the case of a patient who had a pseudoaneurysm of the popliteal artery that resulted from acupuncture therapy for osteoarthritis of the knee. The patient was successfully treated by direct repair of the pseudoaneurysm.

7/44. Pseudoaneurysm of the abdominal aorta caused by acupuncture therapy.

    Acupuncture is a major treatment modality used in Oriental medicine to control chronic pain. However, several complications have been reported, including spinal cord injury, pneumothorax, and subcutaneous pseudoaneurysm, according to the puncture sites. We report the case of a pseudoaneurysm of the abdominal aorta caused by acupuncture.

8/44. hepatic artery pseudoaneurysm following laparoscopic cholecystectomy.

    The authors describe a hepatic pseudoaneurysm following laparoscopic cholecystectomy in a child. It arose from a hepatic artery that was ligated during surgery and was supplied by collaterals from the superior right branch. Because of the risk of hepatic infarction and recanalization of the pseudoaneurysm by new collaterals, the authors decided not to occlude the superior right branch, but to embolize the aneurysm itself with cyanoacrylate. Since the intra-arterial approach was not feasible, a transhepatic puncture was successfully performed.

9/44. Direct percutaneous puncture of a cervical internal carotid artery aneurysm for coil placement after previous incomplete stent-assisted endovascular treatment.

    Direct percutaneous puncture for coil placement has been described for visceral aneurysms, but the procedure has not been previously reported for aneurysms of the head and neck. We report a case in which stent-assisted endovascular treatment was successfully combined with direct puncture for additional coil placement to treat a symptomatic giant aneurysm of the cervical internal carotid artery.

10/44. Percutaneous puncture and pre-operative cyanoacrylate obliteration of a traumatic false aneurysm of an angular artery branch.

    We report a case of traumatic false aneurysm developed in the right glabella in a 5-year-old boy 3 weeks after an innocuous fall. Ultrasound, CT and facial arteriography did not reveal the feeding artery. After direct puncture of the glabellar bulge and rapid aspiration of blood, percutaneous contrast agent infusion revealed that the false aneurysm was supplied by the contralateral angular artery. Intralesional obliteration with cyanoacrylate was subsequently performed smoothly. Succeeding excision was easy and the cosmetic outcome was excellent.
