OBJECTIVETo evaluate the novel method of combinedly use of occluder and bare stent in the treatment of aortic dissection with distal tear at visceral branches.

METHODSFrom April 2010 to September 2012, 6 patients (5 male and 1 female patients, aged from 29 to 62 years, mean 47.2 years) were diagnosed as Stanford type B aortic dissection that been revealed by CT angiography. The main tears were sealed with stent-grafts firstly, and then the tears at the visceral branch area were evaluated that impossible to close spontaneously. Atrium septal defect occluder and ventricular septal defect were implanted at the tears with the anterior disc in false lumen, while the posterior disc in the true lumen. After that, the bare stents were implanted in the true lumen to pull the occluders on the aortic wall.

RESULTSAmong the 6 procedures, occluders were successfully implanted in 5 cases, and 1 failed anchoring at the tear, and the alternative method of coils embolization was applicated. After all the procedures, the immediate aortogrophy revealed that the false lumen disappeared in the 5 cases that occluders were used, and the visceral branches were all patent. No paraplegia, lesion of visceral organs or other complications occurred. All the cases were followed at least 5 months. There was one endoleak due to a non-sealed tear at the descending aorta, one new-occurred small tear in the descending aorta but with no communication to the false lumen.

CONCLUSIONSThe combinedly use of occluder and bare stent in the treatment of aortic dissection with tears at the visceral branch area is a sum of two simple technique plus each other. It is easily to master. The lesions at the aortic that ordinary stent-grafting incapable to seal are successfully solved then. The huge trauma of open or hybrid procedures are avoided.

Peripheral artery aneurysms,with low incidence and complex anatomic structure,often involve important branches.This paper introduces a new surgical technique-sleeve shaping on the basis of two cases.The basic data,including characteristics,imaging,operation and follow-up data of the cases,were collected.The data were then combined with the previous literature for explaining in detail that this technique can be used as a supplementary method of reconstruction following resection or endovascular repair.

OBJECTIVETo evaluate the effect of aneurysm clipping and partial blood clot removal in the subarachnoid space on hemorrhage volume in the subarachnoid space and cerebral vasospasm in patients with different Fisher grades.

METHODSPatients with subarachnoid space hemorrhage (SAH) of Fisher Grades I, II, and III were subdivided into control and treatment groups for comparative studies. The patients with unruptured intracranial aneurysms (UIAs) undergoing aneurysm clipping were also compared with Fisher grade I control subgroup. OxyHb levels in the cerebrospinal fluid and cerebral blood flow volume (CBFV) of the middle cerebral artery (MCA) were measured on days 3, 7, and 13 day after SAH.

RESULTSThe patients with UIAs and Fisher Grade I control subgroup showed significant differences in OxyHb levels on day 3 in CBFV of the MCA on days 3 and 7 (P<0.05). In the SAH groups, OxyHb levels increased significantly on day 3 day in the treatment subgroups of Fisher Grades I and II, but declined significantly on days 7 and 13 in Fisher Grade III treatment subgroup as compared with the corresponding control subgroups (P<0.05); in Fisher Grade I group on days 3 and 7 and in Fisher Grade II group on day 7, CBFV of the MCA increased significantly in the treatment subgroups, but in Fisher Grade III group, CBFV decreased significantly on days 7 and 13 compared with the control subgroup (P<0.05). A positive correlation was found between OxyHb levels in the cerebrospinal fluid and CBFV of the MCA (P<0.05).

CONCLUSIONFor patients with Fisher Grades I and II aneurysms, craniotomy may increase hemorrhage volume in the subarachnoid space and exacerbate cerebral vasospasm, but for Grade III patients, aneurysm clipping and blood clot removal shows beneficial effects in terms of reducing hemorrhage volume and relieving cerebral vasospasm.

OBJECTIVETo evaluate the efficacy of the surgery with lateral supraorbital approach for clipping anterior circulation aneurysms.

METHODSThe clinical data of 99 patients with anterior circulation aneurysms who underwent a clipping via lateral supraorbital approach from October 2012 to September 2014 and 75 patients, who underwent a clipping via pterional approach from January 2010 to December 2011 in the second Affiliated Hospital, Zhejiang University School of Medicine were reviewed. The operative duration, prognosis, residual rate and rupture rate during surgery were compared between two groups.

RESULTSThe patients by lateral supraorbital approach had a shorter operative duration, namely 37~61 min less than that in the patients by pterional approach. No difference were found in residual rate and rupture rate between two groups. The Glasgow Outcome Scale (GOS) at 3 months after surgery showed no significant difference between two groups.

CONCLUSIONThe lateral supraorbital approach can be used safely and effectively with shorter operative duration and less tissue damage for treatment of patients with anterior circulation aneurysms.

OBJECTIVETo review the surgical modality with pterional keyhole approach in treatment of anterior circulation aneurysm.

METHODSThree hundred and thirteen patients with ruptured anterior circulation intracranial aneurysm treated surgically with pterional keyhole approach between January 2009 and June 2014 in Department of Neurosurgery, the Second Affiliated Hospital of Zhejiang University School of Medicine, were included in the analysis. Complete occlusion rate of aneurysms and incidence of major complications including delayed cerebral ischemia and chronic hydrocephalus were documented. Surgical outcomes at 6-month follow up were assessed by modified Rankin Scale.

RESULTSTotally 348 aneurysms were treated with pterional keyhole approach, 326 aneurysms were completely clipped, 16 aneurysms were partly clipped, and 6 aneurysms were wrapped with gauze material. Among 313 patients, 15 patients (4.79%) suffered from delayed cerebral ischemia, and 10 patients (3.19%) suffered from hydrocephalus. At the 6-month follow up, the rate of good outcome was 66.77% (209/313).

CONCLUSIONSThe pterional keyhole approach can be used to clip most of anterior circulation aneurysms, and it seems to have advantages over the traditional approaches with lower incidence of complications and similar outcomes.
