From Jan/2001 to Nov/2001 at the Cardio–vascular ward Cho Ray Hospital there were 20 patients who were popliteal artery injured. The causes are that motorbike accident: 18 cases; block ferrous compressed: 01 case; jumping: 01 case. The treatment is that cutting the arterial damaged and transplantation by saphenous vein: 06 cases; amputation 1/3 inferior femoral: 04 cases (two cases for premarie amputation, two cases for 24 hours after operating). Result: 16 patients were checked after operating (ECHO Doppler: 12 cases, DSA: 04 cases). All them have good results: the anastomosis is not stenosis or obstruction.

OBJECTIVETo evaluate the clinical application of the medial approach for repairing popliteal artery injuries.

METHODSFrom 2002 to 2008, 11 cases of popliteal artery injuries had been repaired via the medial approach. Of these cases, 8 had limb fractures, 1 had knee dislocation, and 2 had visceral injuries. Ten popliteal arteries were anastomosed directly while one was repaired with a great saphenous vein graft.

RESULTSThe operation time ranged from 3 to 4 hours (averaging 3.6 hours). All the injured limbs survived. At the follow up, 8 legs recovered the full function, 2 had minor contracture, and 1 serious Volkmann's contracture without amputation.

CONCLUSIONThe medial approach for repair of the popliteal artery is effective, applicable, and more advantageous to the management of multi-injures.

BACKGROUNDPeripheral artery disease accounts for more than 400 000 hospitalizations in the USA and results in symptoms ranging from claudication to gangrene. Recent advances in endovascular techniques have led to a more aggressive approach for treating peripheral artery disease. The aim of this retrospective study was to evaluate the outcomes of endovascular interventions on TransAtlantic InterSociety Consensus (TASC) II C and D femoropopliteal occlusive disease.

METHODSData for all patients undergoing endovascular interventions for femoropopliteal occlusive disease from December 2007 through December 2010 were reviewed. Demographic data, risk factor data, preprocedural and postprocedural ankle-brachial indices, technical success rates, and complication rates were obtained. Primary, assisted primary, and secondary patency were determined by Kaplan-Meier survival analysis. Univariate and multivariate analyses were performed to identify factors adversely affecting primary patency.

RESULTSThe study group included 52 TASC II C and 106 TASC II D limbs in 126 patients (mean age, (68.0 ± 18.0) years). The technical success rate was 91.1%. Complications occurred in 19 limbs (12.0%), including 8 (5.1%) major complications. The mean follow-up period was (17.6 ± 5.1) months (range, 12.0 - 48.0 months). Primary patency rates at 1, 2, 3, and 4 years were 95%, 78%, 74%, and 74% in TASC II C lesions and 89%, 62%, 52%, and 52% in TASC II D lesions, respectively. Secondary patency rates at 1, 2, 3, and 4 years were 97%, 94%, 94%, and 94% in TASC II C lesions and 97%, 95%, 83%, and 83% in TASC II D lesions, respectively. It is significantly different between primary patency rates (P < 0.05) but not secondary patency rates of TASC II C and D groups (P > 0.05). Predictors of restenosis/occlusion included hyperlipidemia, lesion length, and popliteal artery involvement.

CONCLUSIONSEndovascular treatment of TASC II C and D femoropopliteal artery occlusion has a high technical success rate with favorable mid-term secondary patency rate. Hyperlipidemia, lesion length, and popliteal artery involvement were independent risk factors for in-stent restenosis.

OBJECTIVETo assess the clinical efficacy of retrograde puncture subintimal angioplasty (SIA) for treatment of occlusive diseases in the long segment of the infrapopliteal artery.

METHODSThe clinical data of 50 patients with occlusive diseases in the long segment of the infrapopliteal artery were retrospectively analyzed. The patients were divided into control group (n=25) and study group (n=25) and received antegrade SIA and retrograde puncture SIA with long balloon after the failed antegrade SIA, respectively. The ankle brachial index (ABI) and the temperature of the infrapopliteal skin before and after the operation were compared between the two groups.

RESULTSThe technical success rate was 100% in the 50 patients, who showed obviously improved ischemic symptoms without serious complications. The ABI of the study group increased from 0.31 ± 0.12 before the treatment to 0.47 ± 0.09 at 24 h, 0.56 ± 0.06 at 1 week, 0.63 ± 0.07 at 3 months, 0.58 ± 0.06 at 6 months, and 0.49 ± 0.03 at 12 months after the treatment, and the skin temperature increased from 28.13 ± 2.45 before the operation to 33.87 ± 1.24, 34.16 ± 0.44, 34.19 ± 0.25, 32.45 ± 0.25, and 31.05 ± 0.21 at the corresponding time points after the treatment, respectively, showing significant improvements after the operation (P<0.05). ABI, skin temperature and the patency rate were similar between the two groups at each of the postoperative time points (P>0.05).

CONCLUSIONRetrograde puncture SIA is safe and effective for treatment of arteriosclerosis obliterans in the infrapopliteal arteries with a high clinical success rate and a low complication rate after the failure of antegrade SIA.

BACKGROUNDDiabetic lower limb ischemia is a serious complication of diabetes mellitus. This study was conducted to investigate the effectiveness of distal arterial bypass treatment in diabetic patients with lower limb ischemia.

METHODSFrom July 2000 to July 2004, 96 lower limbs of 82 diabetic patients (type 2) with severe lower limb ischemia were treated in Xuan Wu Hospital. Arterial bypass with femoro-popliteal polytetrafluoroethylene (PTFE) and graft-tibial autologous grafts was performed on 31 limbs (32.3%). Popliteal-tibial artery bypass alone was performed on 22 limbs (22.9%). Combined iliac artery stenting, femoro-popliteal artery PTFE graft bypass, and graft-tibial artery autologous graft bypass was performed on 12 limbs (12.5%), and femoro-tibial artery graft bypass was performed on 10 limbs (10.4%). Popliteal-tibial-pedal artery graft bypass was performed on 7 limbs (7.3%).

RESULTSArterial grafts in 92 limbs of 79 patients were patent on discharge. Three patients with 4 ischemic limbs (3.7%) died of respiratory failure 12 hours, 3 days and 7 days after operation respectively. Early operation success rate was 96.3% (79/82). Graft patency rate of patients on discharge was 95.8% (92/96). The short-term total effectiveness rate was 83.3% (80/96). Foot ulcer healing rate was 35.7% (10/28). 97.4% (75/77) patients were followed up for a mean of 13.5 months. The long-term total effective rate was 80.7% (71/88). The total amputation rate was 4.5% (4/88). Mortality was 4.5%. The total graft patency rate was 90.9% (80/88).

CONCLUSIONIn the treatment of diabetic foot, distal lower limb arterial bypass can help to avoid amputation or lower the amputation level, and may promote foot ulcer healing and improve patient's quality of life.

Failure to recognize popliteal artery injury and restore vessel continuity of flow after blunt trauma is a major cause of lower extremity amputation and morbidity. A high index of suspicion and early recognition of the injury are paramount for limb salvage. We experienced a rare case of poplitial artery occlusion with the presence of arterial pulses due to collateral circulation after blunt trauma. Expeditious revascularization was achieved by using posterior approach, allowing two surgical teams to work simultaneously. This case illustrates that, even in the absence of knee dislocation, surgeons must always consider the possibility of a popliteal artery damage whenever a blunt trauma near the knee.

OBJECTIVETo investigate the early diagnosis and treatment for trauma around the knee with popliteal vascular injury.

METHODSA retrospective analysis was employed to analyze the clinical data from 15 patients (9 males and 6 females were with a mean age of 39.2 years old,ranging from 26 to 62 years old) with fracture or dislocation around the knee with popliteal vascular injury from January 2007 to January 2013. Combined with clinical symptoms and signs, oxygen saturation monitors, color ultrasound, DSA angiography and interventional surgery were used to determine the vascular injury. The knee fracture and dislocation were fixed with hybrid external fixation and plate-screw fixation, respectively. Then, the blood circulation was reconstructed by thrombectomy, repair and autologous vein graft for individual injured vascular. The average total operation time, average hospitalization days, predictive salvage index (PSI), average blood transfusion amount, average medical expenses and infection cases were recorded to determine the effect of early diagnosis and treatment.

RESULTSThere was one patient with death, 8 patients with amputation, and 6 patients with successful repair surgery for popliteal artery, anterior tibial and posterior tibial arteries. These six patients with surviving limbs were followed up for an average of 28.3 months (ranged, 12 to 60 months). Among the 6 successful patients, the joint function of 4 patients was good and excellent.

CONCLUSIONThe trauma around the knee with popliteal vascular injury is characterized by complex and serious injury, easy misdiagnosis and loss diagnosis, poor prognosis and high risk of amputation. The early diagnosis of trauma around the knee with popliteal vascular injury should depend on the mechanism of trauma, local anatomical characteristics of injury site, clinical presentations and appropriate auxiliary examinations. The appropriate indications for limb salvage and amputation should be used to achieve more effective clinical results.
