Value of the deep femoral artery as alternative inflow source in infrainguinal bypass surgery.
2013
Background The purpose of this study was to analyze the long-term results of infrainguinal bypass surgery using the deep femoral artery (DFA) as the inflow source. Methods Between 1998 and 2011, 88 bypasses of the lower limb were placed in 86 patients (mean age 71 years) using the deep femoral artery as inflow. Patients' records were retrieved from a computerized database and analyzed retrospectively. Results Critical limb ischemia (rest pain/tissue loss) was the indication in the majority (87.5%) of cases. The distal anastomosis of the bypass grafts was located at the popliteal level in 32 cases and the tibial (pedal) level in 52 cases, respectively, with the autologous vein as conduit in …
Use and durability of femoral vein for autologous reconstruction with infection of the aortoiliofemoral axis.
2014
Objective To analyze early and late mortality, venous morbidity, reinfection, and freedom from reintervention after using the femoral vein (FV) for vascular reconstruction with infection of the aortoiliofemoral axis. Methods By reviewing our database, 86 patients could be identified with implantation of FV grafts in infected fields between November 1995 and July 2012. The patient records were retrospectively analyzed and follow-up information obtained from patients or their general physician. Seventy-one patients presented with prosthetic graft infection and 15 with an infected aneurysm. For data analysis, patients were divided into an aortoiliac (n = 67) and a femoral group (n = 19). Study…
Strategies for endovascular aortic repair in aortobronchial and aortoesophageal fistulas.
2013
Objective To report our experience of thoracic endovascular aortic repair (TEVAR) for acute bleeding originating from the thoracic aorta in patients with aortobronchial fistula (ABF) or aortoesophageal fistula (AEF). Patients and Methods A total of nine patients (three woman) were treated from September 1995 to March 2012 by TEVAR for ABF (n = 5) and AEF (n = 4). The implants (N = 14) were introduced with fluoroscopic guidance via the aorta (n = 1), the iliac (n = 2), or femoral (n = 11) artery, respectively. Results All aortic lesions could be sealed successfully. Perioperative morbidity was 0% in the ABF group and 50% (2 of 4) in the AEF group and no procedure-related morbidity was noted …
Malignant and Unclear Histological Findings in Incidentalomas
2007
<i>Background:</i> The management of incidentalomas with tumor size 3 cm and larger is still under controversial discussion. <i>Study Design:</i> Clinical charts of 65 patients who underwent adrenalectomy for an incidentaloma were reviewed. <i>Results:</i> Sixty-five patients were operated. There were 28 men and 37 women with a median age of 56.9 years. Median size of all resected lesions was 4.1 cm. Indications for surgery were tumor size equal and larger than 3 cm, recurrent pain, hormone status and patients’ fear of malignancy. In 45 patients, the adenomas did not meet the defined criteria of malignancy. There were 9 cases of adrenal hyperplasia, and t…
Co-expression of receptor tyrosine kinases in esophageal adenocarcinoma and squamous cell cancer.
2008
This study aimed to define the co-expression pattern of target receptor tyrosine kinases (RTKs) in human esophageal adenocarcinoma and squamous cell cancer. The co-expression pattern of vascular endothelial growth factor receptor (VEGFR)1-3, platelet-derived growth factor receptor (PDGFR)alpha/beta and epidermal growth factor receptor 1 (EGFR1) was analyzed by RT-PCR in 50 human esophageal cancers (35 adenocarcinomas and 15 squamous cell cancers). In addition, IHC staining was applied for the confirmation of the expression and analysis of RTK localisation. The adenocarcinoma samples revealed VEGFR1 (97%), VEGFR2 (94%), VEGFR3 (77%), PDGFRalpha (91%), PDGFRbeta (85%) and EGFR1 (97%) expressi…
