Knowledge of cytogenetic analysis for synovial sarcoma in sarcomatoid variant renal cell carcinoma.

Sarcomatoid change in a renal tumor should undergo cytogenetic analysis of t(x;18) to prevent a missed diagnosis of synovial sarcoma. Surgeons should be vigilant regarding pathological correlation.

Virtual histology intravascular ultrasound in carotid interventions.

Purpose: To report early clinical experience with virtual histology intravascular ultrasound (VH IVUS) in carotid endoluminal repair.

Technique: A 2.9-F, 20-MHz catheter that utilizes computer software to demonstrate the histological components of arteriosclerotic plaque was evaluated during carotid angioplasty and stenting.

Virtual histology and color flow intravascular ultrasound in peripheral interventions.

The quality and interpretation of intravascular ultrasound (IVUS) imaging has been revolutionized in recent years by two new and major advances: virtual histology and color flow IVUS. Virtual histology intravascular ultrasound (VHIVUS) is a catheter-based technology where IVUS is generated from the transducer on the catheter tip and the reflected signals from the artery wall produce a color-coded map of the arterial disease. Different histological constituents of the plaque produce different reflected signals and these are assigned different colors (dark green, fibrous; yellow/green, fibrofatty; white, calcified; red, necrotic lipid core plaque).

Endovascular significance of the external carotid artery in the treatment of cerebrovascular insufficiency.

Purpose: To present illustrative cases that demonstrate the feasibility and clinical benefits of endovascular treatment of external carotid artery (ECA) stenoses in patients with occluded internal carotid arteries (ICA).

Case Reports: Three patients with symptoms of cerebrovascular insufficiency and a stenosis of the ECA in the presence of occluded ICAs and diseased vertebral arteries were treated successfully by percutaneous stent or stent-graft implantation with and without cerebral protection.

Conclusions: The ECAs play an important role in providing collateral blood supply to the brain through the many connections between branches of the ECA and cranial branches of the ICA and vertebral arteries.

Frequency and risk factor of abdominal wound dehiscence.

Objective: To find out the frequency of abdominal wound dehiscence (AWD) in a tertiary care hospital and the assessment of associated risk factors.

Design: a cross sectional analytical study.

Place And Duration Of Study: This study was carried out at Nishter Hospital Multan between May 1998 to May 2000.
