Can a small blood vessel prosthesis be derived from heterologous foreign body reactive tissue?

Journal of Biomedical Materials Research, 1979
AbstractThis study investigated as a small diameter vascular replacement the tissue formed adjacent to an implanted cylindrical foreign body, heterologously transplanted. Grafts of 4 mm i.d. were grown in rabbits and transplanted to dogs as segmental carotid and femoral artery replacements. These maintained 50% patency after 3 weeks.

[Urologic complications after implantation of aortofemoral blood vessel prosthesis].

Der Urologe. Ausg. A, 1997
After implantation of aorto-femoral grafts, primary ureteral lesions and secondary ureteral obstructions are the most important urological complications. Surgical repair carried out as quickly as possible, including reanastomosis without tension and covering with a peritoneal patch or omentum interposition, seems the best means of preventing secondary ...

[Injury of the inguinal blood vessels in implantation of hip joint prosthesis].

Der Unfallchirurg, 1992
Vascular injuries during or after total hip replacements have often been reported. In 2257 artificial hip joint replacements, we observed 8 cases of vascular injuries requiring reconstruction (3 cases), suturing (2 cases), end-to-end anastomosis (1 case), or ligature (2 cases) performed by a vascular surgeon.

[Morphology of abdominal aortic aneurysms with reference to endovascular blood vessel prosthesis].

Swiss surgery = Schweizer Chirurgie = Chirurgie suisse = Chirurgia svizzera, 1996
The purpose of this report was to describe the frequency and morphology of infrarenal aortic aneurysms suitable for endovascular tube graft repair. Preoperative abdominal CT scans of 89 patients undergoing open tube graft repair were analyzed retrospectively by measurements of lengths and diameters of the aneurysms.

A hybrid electrospun PU/PCL scaffold satisfied the requirements of blood vessel prosthesis in terms of mechanical properties, pore size, and biocompatibility

Journal of Biomaterials Science, Polymer Edition, 2013
In this study, a novel hybrid polyurethane/polycaprolactone (PU/PCL) tubular scaffold was fabricated using the electrospinning process for blood vessel prosthesis applications. The detailed microstructure and material properties such as porosity, tensile and bust strength, contact angle, and biocompatibility were investigated and compared with those of

[Treatment of pyogenic complications after reconstructive surgery on blood vessels with use of synthetic prosthesis].

Khirurgiia, 1998
Factors influencing result of surgical treatment of patients with festered postoperative wounds have been studied. Algorythm of determination of tactics for examination and treatment of this category of patients was established. The results obtained are based on the analysis of personal surgical treatment autcomes in 1526 patients with decompensated ...

[In vitro evaluation of blood vessel prosthesis dilatation--Dacron and PTFE--a new measuring technique].

Zentralblatt fur Chirurgie, 1998
Dilatation is the most significant complication of prosthetic vascular grafts. It is suspected to be a nidus of other graft complications. There have been a few studies on in-vitro-dilatation of the prosthetic vascular grafts. This is due to the lack of an effective and simple method to measure the transverse dilatation of the graft. We developed a new

[Diagnosis and surgical management of carotid body tumor as well as blood vessel prosthesis' role].

Zhonghua er bi yan hou tou jing wai ke za zhi = Chinese journal of otorhinolaryngology head and neck surgery, 2011
To analyse the diagnostic and therapeutic aspects of carotid body tumor (CBT).Seven patients with CBT had been hospitalized between 2003 and 2006. The clinical data was analyzed retrospectively. The preoperative evaluation included angiography in 7 patients. Most of them had an asymptomatic cervical lateral mass. Only one patient had the hoarseness and
