The experience in diagnosis and treatment of bleeding complications in severe acute pancreatitis (SAP) by transcatheter arterial embolization was summarized. The clinical data of 19 SAP patients complicated with intra-abdominal bleeding in our hospital from Jan. 2000 to Jan. 2003 were analyzed retrospectively and the therapeutic outcome of TAE was evaluated statistically. The results showed that the short-term successful rate of hemostasis by TAE was 89.5% (17/19), the incidence of re-bleeding after TAE was 36.8% (7/19) and the successful rate of hemostatis by second TAE was 71.4% (5/7). It was concluded that the intra-abdominal bleeding in SAP was mainly caused by the rupture of erosive/infected pseudoaneurysm. Mostly, the broken vessels were splenic artery and gastroduodenal artery; In terms of emergence hemostatis, TAE is the most effective method. Surgical hemostasis is necessary if hemostasis by TAE is failed or re-bleeding occurs after TAE.

OBJECTIVETo evaluate the therapeutic effect of embolization combined with endovascular stenting in the for treatment of intracranial pseudoaneurysms.

METHODSSeventeen patients with intracranial pseudoaneurysms received endovascular treatment with coil placement, NBCA glue embolization and endovascular stenting, and the therapeutic effect was evaluated according to the findings in immediate postoperative and follow-up angiography.

RESULTSFatal aneurysm rupture occurred in 1 case during embolization, and the surgical procedures were carried out smoothly in the remaining 16 cases. The aneurysm cavity dense coil packing ratio was 50% in coil embolization group and 42.9% in stent-assisted coil embolization group. In the follow-up for 3 months to 2 years, 2 patients in coil embolization group experienced pseudoaneurysm recurrence and were managed successfully with additional embolization with coils and stent. Aneurysms were not found postoperatively in stent-assisted coil embolization group.

CONCLUSIONEmbolization combined with endovascular stenting is a safe and effective treatment of intracranial pseudoaneurysms with minimized risk of recurrence.

BACKGROUNDPseudoaneurysms (PAs) are common vascular abnormalities predominantly arising from a disruption in the integrity of the arterial wall. The potential complications of PAs are usually unpredictable and carry high rates of morbidity and mortality. This paper presents our experience with various treatment strategies for PAs.

METHODSFifty-four patients with 55 PAs were diagnosed by non-invasive imaging examination. The etiology of PAs included trauma (33/55), infection (5/55), iatrogenic (6/55), and idiopathic (11/55). Different procedures including ultrasound (US)-guided compression, endovascular treatment, and surgery were performed depending on the location of PAs, size of the sac and neck, and characteristics of the donor artery. The methods of endovascular treatment included embolization of parent artery, the PA sac, or implantation of a stent-graft. Follow-up was performed using US or CT and ranged from 1 day to 24 months (average 16.7 months).

RESULTSIn all 54 patients, 3 patients with superficial PAs were treated by US-guided compression, while 44 patients with 45 PAs located in the head and neck (n = 20), viscera (n = 10) or extremities (n = 15) were treated by endovascular treatment. Nine patients with PAs located in the head and neck (n = 2) or extremities (n = 7) were treated by surgery. Among them, one patient underwent endovascular treatment combined with surgery and 1 was treated by surgery after unsuccessful US-guided compression. In the 3 patients treated with US-guided compression, 2 were successfully treated while the remaining patient required additional surgery. Primary technical success of endovascular management was 97.7% (43/44) and the cure rate was 95.5% (42/44). In the surgery group, 4 patients recovered well, 1 patient was cured by endovascular treatment combined with surgery, 2 cases underwent amputation, 1 patient died of multi-organ failure and 1 patient was paralysed.

CONCLUSIONSMinimally invasive interventional techniques are established treatment methods for PA with favorable success rates and minimal morbidity. The therapeutic options should be tailored to the location, size and rupture risk of PA, condition of the donor artery and existing comorbidity.
