OBJECTIVETo explore the causes, prevention, and management of the complications during intracranial aneurysm embolization with controllable coils (mechanical detachable spiral, MDS; and Guglielmi detachable coil, GDC).
METHODSRetrospective review of 120 cases with 125 intracranial aneurysms embolized with controllable coils from March 1995 to July 1999 was conducted. The 20 accidents (in 18 cases) including aneurysm rupture, over-embolization, protrusion of coil end into the parent artery, and thrombosis of the parent artery were analyzed.
RESULTSAmong the 20 accidents, there were 6 aneurysm ruptures, 6 over-embolizations (in 5 cases), 6 coil protrusions, and 2 thromboses (one was secondary to coil protrusion). The embolization-related mortality was 3.33% (4/120), the permanent neurological deficit was 1.67% (2/120), and the transitory neurological deficit was 3.33% (4/120). The occurrence and outcome of the complications were related to the embolizing technique, the pattern of aneurysm and its parent artery, the imperfection of embolic materials, and the observation and management during embolization.
CONCLUSIONSkilled embolizing technique, better understanding of the angio-anatomy of an aneurysm and its parent artery, correct judgement and management during embolization, and improvement of embolic materials are beneficial to the reduction of complications and to the melioration of the outcome of complications.

In recent years, in the absence of venous component, dilated, overlapping, and tortuous arteries forming a mass of arterial loops with a coil-like appearance have been defined as pure arterial malformation (PAM). It is extremely rare, and its etiology and treatment have not yet been fully elucidated. Here, we reported 2 cases of PAM with associated aneurysmal subarachnoid hemorrhage in this paper. Both patients had severe headache as the first symptom. Subarachnoid hemorrhage was found by CT and computed tomography angiography (CTA) and PAM with associated aneurysm was found by digital subtraction angiography (DSA). In view of the distribution of blood and the location of aneurysms, the aneurysm rupture was the most likely to be considered. Based on the involvement of the lesion in the distal blood supply, only the aneurysm was clamped during the operation. It used to be consider that PAM is safety, because of the presentation and natural history of previously reported cases. Through the cases we reported, we have doubted about "the benign natural history" and discussed its treatment. PAM can promote the formation of aneurysms and should be reviewed regularly. The surgical indications for PAM patients with aneurysm formation need to be further clarified. Management of PAM patients with ruptured aneurysm is the same as that of ruptured aneurysm. Whether there are indications needed to treat simple arterial malformations remains to be further elucidated with the multicenter, randomized controlled studies on this disease.

An autopsy case of sudden death induced by alimentary tract hemorrhage was presented, which was caused by the unexpected rupture of clinically unrecognized tuberculous abdominal aortic aneurysm (TAAA). The initial diagnosis was made of the syndrome of coronary heart disease and hypertensive disease. The detailed autopsy showed that the alimentary tract hemorrhage was caused by a sudden rupture of the mass after posture changing was ascertained as the cause of death. The diagnosis of TAAA was determined by the autopsy findings. Analysis for the medical dispute of TAAA was described, and the difficulty of the diagnosis and medico-legal implications were also discussed.

Hemobilia, in patients with the diagnosis of polyarteritis nodosa, is rare at clinical presentation and has a grave prognosis. We describe a case of massive hemobilia, due to aneurysmal rupture, in a patient with polyarteritis nodosa. A 39-year-old man was admitted to the hospital with upper abdominal pain. The patient had a history of partial small bowel resection, for intestinal infarction, about 5 years prior to this presentation. Abdominal computed tomography demonstrated multiple high attenuation areas in the bile duct and gallbladder. Hemobilia with blood seepage was visualized on endoscopic retrograde cholangiopancreatography; this bleeding stopped spontaneously. The following day, the patient developed a massive gastrointestinal bleed with resultant hypovolemic shock. Emergent hepatic angiogram revealed multiple microaneurysms; a communication was identified between a branch of the left hepatic artery and the bile duct. Hepatic arterial embolization was successfully performed. The underlying disease, polyarteritis nodosa, was managed with prednisolone and cyclophosphamide.

A recurrent aneurysm at the anastomosis site or the remaining artery frequently occurs after the operative treatment of an aneurysm in Behcet's disease despite anti-inflammatory medication. Herein, a ruptured left renal artery stump aneurysm in a patient with Behcet's disease, who received a left nephrectomy, aorto-biiliac bypass and heterotopic autotransplantation of the right kidney for the treatment of an abdominal aortic aneurysm and renal hypertension one year prior to this admission, is reported. An aneurysm and rupture occurred despite the administration of anti-inflammatory medications while monitoring of the clinical findings, such as skin manifestations, erythrocyte segmentation rate (ESR) and C-reactive protein (CRP). Although there is no definite proven treatment modality to prevent recurrent aneurysms at the anastomosis site or a remote artery, close follow-up with anti-inflammatory medications, and surveillance with regular intervals are the only current methods for the prevention and/or to treatment of an arterial complication in patients with Behcet's disease.

A patient received combined spinal-epidural anesthesia for a scheduled total knee arthroplasty. After an injection of spinal anesthetic and ephedrine due to a decrease in blood pressure, the patient developed a severe headache. The patient did not respond to verbal command at the completion of the operation. A brain CT scan revealed massive subarachnoid and intraventricular hemorrhages, and a CT angiogram showed a ruptured aneurysm. Severe headaches should not be overlooked in an uncontrolled hypertensive patient during spinal anesthesia because it may imply an intracranial and intraventricular hemorrhage due to the rupture of a hidden aneurysm.

OBJECTIVETo report the experience in diagnosis and management of bleeding pseudoaneurysms associated with severe acute pancreatitis (SAP).
METHODSThe medical records of 12 patients with bleeding pseudoaneurysms associated with SAP treated between October 1990 and October 2006 were retrospectively reviewed. The etiologies of the 12 patients were gallstones in 6 patients, hyperlipidemia in 3 patients, hyperparathyroidism in 1 patient and the other 2 patients had no definitive causes.
RESULTSAbdominal computed tomography revealed bleeding pseudoaneurysms in 6 of 9 patients. Angiography determined correct diagnosis in 12 patients (12/12). The most involved vessels were peripancreatic arteries. Eight patients were managed by trans-catheter arterial embolization (TAE) as "one point" (a proximal point of the pseudo-aneurysm). Two patients were treated by TAE as "two points" (both distal and proximal to the pseudo-aneurysm). The last two cases were treated by surgery as suture and ligation. Four of the "one point" TAE patients were re-bleeding 4 to 7 days later, and 2 of them were treated with surgery, the other 2 patients were controlled with "two points" TAE. Three patients were died of infection and multiple organ dysfunction syndromes. Overall mortality rate was 25% (3/12).
CONCLUSIONSAngiography is the main diagnostic methods for bleeding pseudoaneurysms in SAP patients. "Two points" embolization and emergency surgery are an effective treatment options in these patients.

We report 2 cases of complicated spontaneous dissection of the celiac artery, which were successfully treated by a stent graft. The first patient was a 47-year-old man who presented with acute abdominal pain. CT scan showed ruptured saccular aneurysm with surrounding retroperitoneal hematoma. The second patient was a 57-year-old man with progressive dissecting aneurysm. Endovascular stent graft was placed in the celiac trunk to control bleeding, and to prevent rupture in each patient. Follow-up CT scans showed complete obliteration of a dissecting aneurysm.
