Objective To report our surgical experience in treating 19 cases of solitary iliac aneurysms (SIA). Methods The clinical data of 19 consecutive patients with SIA between January 1985 and January 2008 were retrospectively reviewed. There were 18 men and 1 woman, aging from 39 to 77 years ( mean 62 ± 7 years). Results There were 30 SIAs in the 19 patients, including 25 ( 83.3% ) common iliac aneurysms, 4 (13.3%) internal ihac aneurysms and 1 (3. 3% ) external iliac aneurysm. Eleven patients ( 57.9% ) had multiple ancurysms, with 9 patients ( 47.4% ) having bilateral SIA. Two patients had coexistent peripheral vascular occlusive disease. There were 2 patients suffering form ruptured SIA, one was saved by emergency operation and one died before an surgery could be attempted. Seventeen patients underwent successful open aneurysmectomy and artificial graft implantation leaving no ischemic complications of the pelvic organs. One patient with right common iliac aneurysm underwent endovascular repair without endoleak. There was no operative death during porioperative period. The surviving patients remained stable and had good patency of grafts during the follow-up period. Conclusions Early management of SIA is important, CT angiogarphy (CTA) is necessary not only to evaluate the SIAs, but also to detect multiple aneurysms or arterial occlusive disease. Close and long-term follow-up is mandatory for the early detection of the formation of new anearysms.

Chinese Journal of Neuromedicine 2012;11(4):383-386
Objective To explore the predictive value of combined ABCD2 scores and tracheal constriction resulted from internal carotid atherosclerosis (ICAS) in cerebral infarction within 7 d of onset of a transient ischemic attack (TIA). Methods The clinical data of 171 patients with TIA,admitted to our hospital from September 2008 to March 2011, were retrospectively analyzed. All patients were evaluated with ABCD2 scale and degrees of tracheal constriction resulted from ICAS were examined by Color Doppler ultrasound.And 7-d follow-up of patients was performed to select those patients appearing cerebral infarction; and then, the relationships between risk of post-TIA cerebral infarction and both ABCD2 scores and degrees of tracheal constriction were analyzed using chi-square test. Results Among 171 TIA patients,39 (22.8%) suffered cerebral infarction within 7 d of onset of TIA.Significant difference of risk of post-TIA cerebral infarction was noted in patients with different ABCD2 scores and degree of tracheal constriction (P<0.05): the higher the ABCD2 scores/ the degrees of tracheal constriction, the higher incidence of cerebral infarction in TIA patients. Conclusion A rather high accuracy may be achieved with ABCD2 scale in the prediction of short-term risk of cerebral infarction after onset of TIA,and a higher accuracy may be expected by combination of ABCD2 scale with carotid atherosclerosis findings.

BACKGROUNDTakayasu's arteritis (TA) is a chronic idiopathic inflammatory disease that affects large and medium size arteries. The brachiocephalic trunk is the most frequently involved site in TA, and multi-vessel lesions are common. Surgical treatment includes vessel reconstruction surgery and percutaneous transluminal angioplasty (PTA). Herein, we report our preliminary experience with surgical treatment of cerebral ischemia caused by cervical arterial lesions due to TA.
METHODSFrom January 2000 to December 2007, 38 patients with cerebral ischemia caused by cervical arterial occlusive lesions due to TA were treated surgically. There were three males and 35 females, with an age range of 15 - 42 years (mean 26.5 years). All patients had operative repairs undertaken. Twenty eight patients received bypass operation and 10 patients received percutaneous transluminal angioplasty. One case with coronary stenosis received coronary artery bypass simultaneously. Patients were followed up for 11 months to eight years.
RESULTSThere were no peri-operative deaths in cerebrovascular reconstruction patients. Symptoms of cerebral ischemia were improved or cured in 25 of 38 patients. There was a low incidence of cerebral reperfusion syndrome. Two patients died at five and seven years after surgery due to heart failure. Another 8 patients (20%) required further surgery for stenosis (5 patients) or anastomotic aneurysms (3 patients). Percutaneous transluminal angioplasty was performed successfully for treatment of aortic and renal lesions. Repeated angioplasty for revascularization was performed in six PTA cases with restenosis after 5 - 24 months.
CONCLUSIONSWhen cerebral perfusion has potential to be affected by TA, a definitive corrective procedure is advised when the patient is relatively stable. Although the recurrence rate is very high, percutaneous transluminal angioplasty is the first choice procedure. Bypass operation is optimal for brachiocephalic-vessel involvement in TA. Cerebral reperfusion syndrome can be avoided by careful selection of the operation method and improved post-operative treatment.

OBJECTIVETo investigate the efficacy of anticoagulation and thrombolysis for deep venous thrombosis via local vein approach and peripheral vein approach to guide clinical treatment.
METHODSThere were 225 patients with deep venous thrombosis admitted from January 2001 to May 2008. The cases were divided into two groups by therapy procedures. The patients in group A were treated by deep femoral vein catheter-directed anticoagulation and thrombolysis, including a total number of 71 patients, with right lower extremity in 20 patients, left lower extremity in 47 patients and bilateral lower extremities in 4 patients. One hundred and fifty-four patients were included in group B with anticoagulation and thrombolysis through peripheral vein, among them right lower extremity in 27 patients, left lower extremity in 121 patients and bilateral lower extremities in 6 patients. The efficacy was evaluated and compared by observing clinical symptoms and measuring of changes in limb circumference.
RESULTSSymptoms were alleviated in all patients in 3 d after the treatment, but the efficacy of group A was better than group B (94.4% vs.69.5%, P < 0.01). The efficacy of group A was also better than group B in 7 days after treatment, but with no significant difference (85.9% vs. 75.3%, P > 0.05). A mean follow-up period was (43 ± 18) months. There was no significant difference in incidence of complication and recurrence between two groups.
CONCLUSIONSThe earlier efficacy of anticoagulation and thrombolysis via femoral vein approach is better than via peripheral vein approach in earlier period of deep venous thrombosis. While peripheral intravenous therapy has also good results after long-term treatment.

OBJECTIVETo determine the serotype and genotype of a sample with ABO blood group discrepancies.
METHODSSerotype was determined with serological method. Sequence specific primer polymerase chain reaction (SSP-PCR) was carried out based on the serotype. Sequences of exons 6 and 7 of ABO gene was analyzed by sequence-based testing (SBT).
RESULTSCompletely agglutinated A antigen, half agglutinated B antigen and weak agglutinated anti-B antibody were detected in both erythrocytes and serum, which suggested presence of a ABw serotype. An A/Bw12 genotype was revealed by B subgroup detection. Sequences of exons 6 and 7 were 278CT, 297GA and 467CT, 526CG, 657CT, 703GA, 796CA, 803GC, 930GA, respectively. The genotype fit with A102/B101 except for a nt278 C>T mutation. Blood group antigen gene mutation database (BGMUT) search has confirmed the mutant allele to be Bw12.
CONCLUSIONAn A102/Bw12 genotype has been found in the Chinese population.
