Vascular Injuries Of Extremities Research Articles

Treatment of vascular non-iatrogenic injuries of upper and lower extremities in tertiary vascular center.

The purpose of this study was to examine demographic and baseline characteristics of patients with vascular injuries of extremities and to define the most relevant factors which influenced an early outcome, as well as limb salvage after the management of vascular trauma. This study used the database that included 395 patients with peripheral arterial injuries, who were treated in the tertiary vascular university center in the period between 2005-2020. Exclusion criteria were isolated thoracic, abdominal and neck injuries as well as iatrogenic injuries and injuries of intravenous addicts. Univariate binary logistic regression analysis and multiple logistic regression were used to determine risk factors for lomb loss (after vascular reconstruction) or mortality. Decision to perform primary amputation (without vascular reconstruction) was based on surgeons' preference and experience. Out of 395 vascular injuries treated in the period 2005-2020, 210 (53.2%) presented with non-iatrogenic vascular injuries of upper and lower extremities were analyzed. According to the univariate regression analysis, hemorrhage as the main clinical manifestation on admission (P=0.035) and early reintervention (P=0.048) increased, while an early patency of repaired artery (0.010) significantly decreased a 30-day amputation rate. Multivariate logistic regression analysis of these three variables showed that only early patency of repaired artery significantly decreased the early amputation rate (P=0.009). Based on presented experience, the patency of vascular reconstruction plays a crucial role in limb salvage in patients with non-iatrogenic peripheral vascular injuries. All factors that might influence the patency should be in focus of improvement.

Revisiting Management Strategies for Popliteal Artery Injuries.

Popliteal artery injuries (PAIs) were reported to own the highest rates of limb loss in vascular injuries of extremities. The complex nature of PAIs makes the treatment more difficult. We aimed to present our cases using our proposed algorithm and revisit the strategies for management. A retrospective study of 45 cases with PAIs managed at the Kaohsiung Chang Gung Memorial Hospital over a 10-year period was conducted. The proposed algorithm for decision making was applied, which contains variables including the interval before surgery, the revascularization being delayed or not, the presence of fasciotomy, the acquisition of preoperative angiography, and the existence of collateral circulation. Whether the injured limbs were salvaged successfully avoiding amputation was recorded. Of all the included 45 patients, the rate of a successful salvage of the injured limb from amputation was 71.1%. Six patients did not receive revascularization because of their poor conditions of the injured limbs. In terms of limb salvage in PAIs, the interval before surgery, the revascularization being delayed or not, the presence of fasciotomy, or the acquisition of preoperative angiography did not make a significant difference (P > 0.05). Instead, an existence of collateral circulation at the distal injured limb was correlated to a significant higher rate of salvage, regardless of having revascularization or not (P = 0.001 and < 0.001, respectively). Seven patients had the injured vessels repaired directly and all were prevented from amputation. In other patients who underwent vascular repair using a graft, vein graft (n = 20) showed a higher successful rate in salvage significantly than Gore-Tex graft (n = 9, P < 0.001). Collateral circulation determines much of the fate of limb salvage in PAIs. As a result, a delayed revascularization could be accepted as long as there is existence of collateral circulation at the distal injured limb. An autologous vein graft is favored when a direct repair is not able to be performed for revascularization. Although fasciotomy was not found to be associated with a successful salvage in this study, its importance could not be neglected and it should be performed when there is an observed or impending compartment syndrome.

Microsurgical treatment of infected extremities after blood vessel prosthesis

Objective To report the clinical effects of microsurgery in treatment of infected extremities after blood vessel prosthesis were transplanted.Methods From Jan.1998 to Dec.2008,8 cases of major vascular injuries in extremities were blood-supplied by cross bridge vascular anastomosis from uninjured extremities,including 4 cases of femoral artery and vein,2 cases of popliteal artery and vein,and 2 cases of brachial artery and vein. Results After 3 years of follow-up,blood circulation of infected extremities were reestablished in each of 8 cases,as well as function and appearance recovered.Conclusion The procedure of cross bridge vascular anastomosis from uninjured extremities may efficiently restitute the blood supply of the infected extremities after blood vessel prosthesis were transplanted,and decrease the rate of amputation.

Blunt vascular trauma in the extremity: diagnosis, management, and outcome.

Blunt vascular trauma in an extremity is an uncommon diagnosis. Considering the complexity of these injuries, it is worthwhile to determine how select factors affect the outcome of the limb and the patient. The objectives of this study were to review the diagnosis, management, and outcomes of patients who sustained blunt vascular injuries in the extremities and relate factors in their treatment to the outcome of the injured extremity. A retrospective review of data on adult and pediatric patients who had a diagnosis of blunt vascular injury in an extremity and underwent some attempt at restoration of vascular flow was conducted. From January 1995 to December 2002, 62 patients (80.3% male; mean age, 33.2 +/- 15.8 years) sustained blunt trauma (mean Injury Severity Score, 14.6 +/- 8.4), with 93 vascular injuries in 65 extremities (16 upper and 49 lower). Hard signs of vascular injury occurred in 41 (66%) patients. An associated fracture and/or dislocation was present in 59 patients (95%). Preoperative arteriograms were obtained in 20 patients (17 occlusions, 2 embolizations, and 1 untreated). Vessel injuries were as follows: 16 upper (brachial artery, 50%) and 63 lower (tibial/peroneal/popliteal, 84%), with ligation being the most common treatment in the latter. Intravascular shunts were used to restore blood flow in 18 vessels (13 arteries and 5 veins) in 13 patients. Delays in diagnosis or treatment occurred in six patients, mostly because of errors in management/judgment. Delayed or late fasciotomies were performed in six patients, and five developed rhabdomyolysis. Six patients died. The age (p = 0.0006), Injury Severity Score (p = 0.0007), and Mangled Extremity Severity Score (p = 0.0009) were significantly different for the survivors compared with the nonsurvivors. Blunt vascular injuries in the lower extremities occur most commonly in the anteroposterior tibial arteries; injured arteries in the proximal upper and lower extremity require resection with interposition grafting, whereas those in the forearm or calf are usually ligated; the amputation rate in 65 injured extremities with blunt vascular trauma was 18.%, which is at least three times that for those who sustain penetrating injury; and delays in diagnosis and treatment are uncommon in these patients with multiple injuries.

A Clinical Study of Vascular Injuries in Extremities

A Clinical Study of Vascular Injuries in Extremities

The effect of acute popliteal venous interruption.

Popliteal vascular trauma continues to be associated with a relatively high morbidity rate when compared to other major vascular injuries in extremities. There is continuing controversy regarding the management of popliteal venous injuries. The advocates of ligation of injured veins have postulated that there is an increased incidence in thrombophlebitis and pulmonary embolism associated with attempted venous repair. There is a paucity of valid statistics supporting either side of this controversy. Clinical experience documented in the Vietnam Vascular Registry and experimental work at Walter Reed Army Institute of Research have supported our more aggressive approach for venous repair. This study evaluates the management of 110 injured popliteal veins without associated popliteal arterial trauma. Nearly an equal number were ligated and repaired. Thrombophlebitis and pulmonary embolism were not significant complications in this series. The only pulmonary embolus occurred after ligation of an injured popliteal vein. However, there was a significant increase in edema of the involved extremity following ligation, 50.9% compared to 13.2% after repair.
