Diagnostic performance of whole brain volume perfusion CT in intra-axial brain tumors: preoperative classification accuracy and histopathologic corre…
2012
Abstract Background To evaluate the preoperative diagnostic power and classification accuracy of perfusion parameters derived from whole brain volume perfusion CT (VPCT) in patients with cerebral tumors. Methods Sixty-three patients (31 male, 32 female; mean age 55.6 ± 13.9 years), with MRI findings suspected of cerebral lesions, underwent VPCT. Two readers independently evaluated VPCT data. Volumes of interest (VOIs) were marked circumscript around the tumor according to maximum intensity projection volumes, and then mapped automatically onto the cerebral blood volume (CBV), flow (CBF) and permeability Ktrans perfusion datasets. A second VOI was placed in the contra lateral cortex, as cont…
Outcome of radical prostatectomy for incidental carcinoma of the prostate
2009
OBJECTIVE To evaluate a contemporary series of patients with incidental prostate cancer detected by transurethral resection of the prostate (TURP) and undergoing radical prostatectomy (RP). PATIENTS AND METHODS Between 1998 and 2004, 1931 patients had TURP for obstructive voiding symptoms and suspected BPH. Incidental prostate cancer was found in 104 (5.4%); 26 of these patients had a RP. The pathological staging and treatment of these patients were reviewed retrospectively and the follow-up results obtained. RESULTS Of the 26 patients who had RP, 17 had T1a and nine had T1b carcinoma of the prostate. After RP, six (35%) in the T1a group had no residual tumour (pT0) and 11 (65%) had pT2 can…
Pathological Evaluation of Mesocolic Resection Quality and Ex Vivo Methylene Blue Injection
2012
BACKGROUND: Although the National Quality Forum has endorsed the harvest of ≥12 lymph nodes as a standard quality indicator for colon cancer surgery, this minimum quantity is not reached in many centers. OBJECTIVE: The aim of this study was to assess the impact of the implementation of a mesocolon evaluation pathological protocol and ex vivo arterial methylene blue injection on the number of nodes harvested after colon cancer resection. DESIGN: A prospective series was compared with a historical group. SETTINGS: This study was conducted by a specialized colorectal multidisciplinary team at a tertiary teaching hospital. PATIENTS: From June 2009 to December 2009, all the specimens after colon…
Detection of flap venous and arterial occlusion using interstitial glucose monitoring in a rodent model.
2010
Background: Free tissue transfer necessitates vigilant postoperative monitoring for vessel occlusion. Unfortunately, most monitoring methods require experienced personnel and are expensive to use. Furthermore, many tests have low sensitivity, low specificity, or significant delay between vessel occlusion and detection. The authors report on a novel method of tissue monitoring that avoids these limitations by tracking interstitial glucose concentration. Methods: Vertical rectus abdominis myocutaneous flaps were elevated in adult rats based on the superior epigastric vessels. Interstitial glucose within the flaps was monitored using a transcutaneous sensor. Interstitial glucose was recorded f…
Solitary fibrous tumor surrounding the carotid sheath.
2009
Solitary fibrous tumors (SFTs) are rare spindle cell neoplasms that are mostly found arising from the pleura. Although SFTs recently have been reported in other regions, they are rare in the head and neck and have often been misdiagnosed due to their rarity. SFTs are benign in most cases. Clinically, SFTs usually manifest as wellcircumscribed, slow-growing, smooth and painless masses. Symptoms are often minimal, although they may include sore throat, difficulty in swallowing, change of voice or trismus. CT-Scan and MRI are the most sensitive imaging procedures used. The treatment of choice is complete surgical excision of the lesion. Because recurrences have been noted up to 30 years after …
Subclavian Stenosis/Occlusion in Patients with Subclavian Steal and Previous Bypass of Internal Mammary Interventricular Anterior Artery: Medical or …
2004
There are only a few published studies on the association between subclavian steal syndrome and ischemic heart disease. The objective of this report is to evaluate the efficacy of subclavian stenoocclusion treatment in patients with subclavian steal syndrome (SSS) and previous cor- onary bypass. Over the last 8 years we observed 207 patients who underwent left internal mammary artery–intraventricular artery (LIMA–IVA) bypass graft. Of these, 31 patients were affected by steno-occlusion of the homolateral subclavian artery. Ten patients (group 1) showed latent vertebral-SSS and were pharmacologically treated. Seven patients (group 2) had an intermittent vertebral-SSS; four patients were trea…
A minimally invasive approach for aortobifemoral bypass procedure
2011
Surgical aortobifemoral bypass procedure for aortoiliac occlusive disease remains the gold standard treatment despite rapidly expanding range of indications for endovascular repair. Besides several disadvantages such as dysparaesthesias, hernias, and unpleasant outcome, transperitoneal exposure of the aorta is also associated with operative autonomic nerve injury. In five male patients, infrarenal aorta was exposed through a small (8 cm) supraumbilical midline incision. Incision of the posterior peritoneum above the infrarenal aorta was limited to 3 cm. A 1 cm infraumbilical incision allowed transperitoneal placement of the distal aortic clamp outside of the operative field. Four centimeter…
The DETOUR procedure: no more need for conventional bypass surgery?
2018
Background Long segment occlusive disease in the superficial femoral artery remains a treatment challenge despite advances in open surgical and endovascular approaches. We report initial clinical results of an entirely new procedure to perform percutaneous femoro-popliteal bypass using the DETOUR System. First-in-human patients were performed in New Zealand from December 2013 to June 2014. After modifications to the technique and devices had significantly refined the procedure, the Detour I Trial commenced. Methods Review of initial results in the first five patients treated at a single site enrolled in IRB-approved, prospective clinical study using the DETOUR System. All patients signed in…
Trans-popliteal hybrid retrograde technique for revascularization of chronic total occlusions of the superficial femoral artery.
2020
Objectives We present the technical description and preliminary results of a hybrid approach for the treatment of chronic total occlusions of superficial femoral artery in the setting of critical limb-threatening ischemia (CLTI). Methods A retrospective analysis of selected case series was performed. A trans-popliteal hybrid technique was carried out in seven limbs (six patients). Open exposure of above-the-knee popliteal artery was performed over its maximum calcification zone. After retrograde recanalization and graft-stenting of the entire superficial femoral artery, endarterectomy of the popliteal artery was performed for debulking and widening of the distal landing zone of the endopros…
Coincident vesical transitional cell carcinoma and prostatic carcinoma. Clinical features and treatment.
1986
Summary— Twenty-two patients with vesical urothelial carcinoma associated with prostatic carcinoma were reviewed. They represented 1.5% of the bladder and prostatic tumours treated in our department within a 12-year period from 1968 to 1979. Their management included several treatment policies, based on the separate assessment of each tumour variant. For non-infiltrating bladder tumours, transurethral tumour resection was combined with hormonal treatment, external radiotherapy or resection of the prostate depending on the stage of the prostatic tumour. Radical cystoprostatectomy was performed for two cases of infiltrating bladder tumour with well localised prostatic tumours. A conservative …
