Autogenous Reconstruction of Infected Arterial Prosthetic Grafts Utilizing the Superficial Femoral Vein1

2001

BACKGROUND Prosthetic infection after reconstructive vascular surgery is a most serious complication, associated with high mortality and amputation rates. Following excision of the infected graft, several methods of reconstruction are available. We present here our experience with autogenous reconstruction of infected prosthetic arterial grafts using the superficial femoral vein (SFV). METHODS From November 1995 to December 1999, we used the SFV in seven patients (mean age 70 years) for reconstruction of an infected aortobifemoral (n = 2), aortoiliac (n = 1), femorofemoral bypass (n = 1), femorotibial (n = 2) and carotid crossover bypass (n = 1). Treatment encompassed complete prosthetic ex…

The effects of optimizing blood inflow in the pedicle on perforator flap survival: A pilot study in a rat model

2020

Background Perforator flaps have led to a revolution in reconstructive surgery by reducing donor site morbidity. However, many surgeons have witnessed partial flap necrosis. Experimental methods to increase inflow have relied on adding a separate pedicle to the flap. The aim of our study was to experimentally determine whether increasing blood flow in the perforator pedicle itself could benefit flap survival. Methods In 30 male Lewis rats, an extended posterior thigh perforator flap was elevated and the pedicle was dissected to its origin from the femoral vessels. The rats were assigned to three groups: control (group I), acute inflow (group II) and arterial preconditioning (group III) dep…

Long-term results after operative treatment of femoral neck fractures with ceramic head prostheses.

2001

ABSTRACT From 1 985-1 990, a total of 277 elderly patients underwent hemiarthroplasty using a ceramic head prosthesis. Average patient age was 81.7 years. Of these, 77 patients were available for follow-up examination in 1993. A standardized score was calculated assessing activity, gait, and hip pain; the average score was 58 out of 78 possible points. Three patients had hip pain, and in 4 patients, radiographic examination revealed protrusio acetabuli. Two of 4 patients underwent revision surgery for replacement of the cup, leaving the stem in situ. Because of the small number of prosthetic-related complications, hemiarthroplasty using a ceramic head prosthesis is the recommended surgical …

Does velocity of dilatation influence the result of dilatation? A postmortem study.

1988

We evaluated the influence of velocity of dilatation on the success of and the vascular damage produced by dilatation. Nonatheroslerotic segments of distal superficial femoral arteries were dilated "fast" (n = 69) or "slow" (n = 45) under standard conditions with balloon catheters. The arterial wall was overstretched between 1% and more than 60%. The success of dilatation rose continuously with increasing overstretching during dilatation. The damage to the arterial wall by dilatation increased discontinuously with increasing overstretching. Dilatation success and damage patterns did not differ in the "slow" and "fast" groups.

Bisphosphonate-associated femoral fracture: implication for management

2008

Studies carried out on individuals being treated long term with bisphosphonates have provoked considerable interest and perplexity about the effect that these drugs have on bone turnover in the long run. In fact the experiences reported by numerous researchers tend to highlight how treatment with high doses of bisphosphonates over many years, of individuals with osteoporosis complicated by or secondary to neoplastic pathologies, causes a suppression of bone turnover that over time predisposes the bone to the accumulation of micro damage that can then result in complicated fractures, as in the case described here.

Supracondylar femoral fracture with an incidental enchondroma of the tibial plateau

2019

The enchondroma is a benign tumor of the endosteal cartilage and it is common in young-adult patients. These tumors are usually diagnosed when a pathologic fracture occurs at the site of the lesion or when they are accidentally discovered during investigations performed for other reasons. This report describes the case of a patient with an enchondroma of the external tibial plateau. Diagnosis was made treating an ipsilateral supracondylar femoral fracture caused by a traffic accident

Intravascular ultrasound imaging of arterial wall architecture.

1992

Intravascular ultrasound (IVUS) is a promising new technique for assessing vascular morphology and structure. Controversy exists whether the three-layer appearance of the arterial wall correctly reflects the histologic structures of the intima, media, and adventitia. We performed an experimental study to clarify the three-layer appearance. The vessel wall architecture was analyzed by IVUS on eight different kinds of plastic cylinders, 24 normal blood vessels from pigs, and 59 human arterial segments. A distinct three-layer appearance was observed on all the plastic cylinders when the ultrasound beam was perpendicular to the wall. A three-layer appearance was also seen in the arterial wall, …
