OBJECTIVE We sought to compare LigaSure Vessel Sealing System tonsillectomy (LT), Harmonic Scalpel tonsillectomy (HST), and cold knife tonsillectomy (CKT). STUDY DESIGN We conducted a prospective study on 161 adult patients undergoing tonsillectomy. Subjects were randomized to LT, HST, or CKT groups, and intraoperative bleeding, operative time,(More)
The Ovation Abdominal Stent Graft System is a trimodular endoprosthesis recently introduced for the endovascular repair of abdominal aortic aneurysm (AAA). It uncouples the stages of stent-graft fixation and sealing with the suprarenal fixation achieved with a long, rigid anchored stent while the sealing onto the neck is accomplished via a pair of(More)
BACKGROUND The aim of this study was to compare the incidence of abdominal and incisional hernias in patients with abdominal aortic aneurysm (AAA) versus patients with aortoiliac occlusive disease (AOD). PATIENTS AND METHODS The study included retrospectively 121 patients, who underwent elective aortic surgery due to AAA (n = 63) or AOD (n = 58) in the(More)
BACKGROUND Aortoenteric fistula (AEF) is a critical clinical condition, which may present with gastrointestinal hemorrhage, with or without signs of sepsis. Conventional open surgical repair is associated with high morbidity and mortality. Endovascular stent graft repair has been attempted, but recurrent infection remains of major concern. We conducted a(More)
We investigated the prevalence of peripheral arterial disease (PAD). Primary Care Health Centers (n = 14) in Thessaly (central Greece) recruited 436 participants, mean age 71 (50-79) years. Peripheral arterial disease was considered present if the ankle-brachial index (ABI) was <0.9 or >1.4 in at least 1 leg. Asymptomatic PAD was defined as an abnormal ABI(More)
OBJECTIVES Remote endarterectomy (RE) is a relatively minimally invasive procedure as an alternative to femoropopliteal above-knee bypass for the treatment of long-segment superficial femoral artery (SFA) occlusion. The objective of this study was to report our experience and to evaluate the long-term outcome. DESIGN Single-center nonrandomized(More)
Cholesterol crystal embolization (CCE) is a possible complication of peripheral endovascular interventions. The diagnosis of CCE is suggested by the gradual onset of peripheral cutaneous manifestations (e.g., livedo reticularis, blue toe syndrome) accompanied by progressive increases in blood urea nitrogen and creatinine levels following an invasive(More)
OBJECTIVE To develop of an isoperistaltic invaginated valve for the treatment of short bowel syndrome. DESIGN Randomised experimental study SETTING University Hospital, Greece MATERIAL 8 mongrel dogs INTERVENTION 90% resection of the small bowel, followed by construction of an invaginated valve one month later. MAIN OUTCOME MEASURES weight loss,(More)
Renal cell carcinoma produces neoplasmatic thrombus that usually invades and progressively grows into the endorenal veins. The thrombus may extend into the ipsilateral renal vein or the inferior vena cava in 15-20% and 8-15% of cases, respectively. These tumors are classified into four categories (I, II, III, and IV) according to the level of cephalad(More)
PURPOSE To evaluate the outcomes of endovascular stent-graft repair of major abdominal arteriovenous fistulas. METHODS The English literature was systematically searched using the MEDLINE electronic database up to January 2009. All reports on endovascular stent-graft repair of major abdominal arteriovenous fistula were considered. Our experience of(More)
