What is   Left Ventricular Assist Device ?
What is Left Ventricular Assist Device ? samer kareem 2,588 Views • 3 years ago

A ventricular assist device (VAD) — also known as a mechanical circulatory support device — is an implantable mechanical pump that helps pump blood from the lower chambers of your heart (the ventricles) to the rest of your body. A VAD is used in people who have weakened hearts or heart failure. Although a VAD can be placed in the left, right or both ventricles of your heart, it is most frequently used in the left ventricle. When placed in the left ventricle it is called a left ventricular assist device (LVAD). You may have a VAD implanted while you wait for a heart transplant or for your heart to become strong enough to effectively pump blood on its own. Your doctor may also recommend having a VAD implanted as a long-term treatment if you have heart failure and you're not a good candidate for a heart transplant.

Mammogram Don’t Always Detect A Breast Implant Rupture
Mammogram Don’t Always Detect A Breast Implant Rupture Stuart Linder 5,038 Views • 3 years ago

As you can see I access the left implant from the periareolar incisions which I made at the lower portion of the areola. As I entered the capsule and begin to remove the implant I noticed a lot of fluid surrounding the implant. Right away I know this is a rupture and that the mammogram was incorrect. Mammograms are very helpful in detecting cancer but often not ruptures. When implants rupture, it is important to have them replaced as soon as possible to avoid excessive scarring in the breasts. If too much scar tissue has accumulated around the deflated implant, it becomes difficult to create a normal breast shape in the future. Therefor know the signs of a ruptured implant such as, painful to touch, visible asymmetry or loss of integrity to the bag. For more information please visit: www.drlinder.com

Removing a Breast Implant from Augmentation
Removing a Breast Implant from Augmentation Stuart Linder 2,202 Views • 3 years ago

Dr. Linder is removing a patients breast implants after having five breast augmentations from three previous surgeons. She has baker 4 capsular contracture and is look forward to having them removed. The most common reasons for removing a breast implant include; heath reasons such as back pain, reoccurring complications and the desire for a different shape or size. For implant removal surgery, Dr. Linder makes an inframammary incision (along the breast crease). The implant can be removed intact, or it may need to be punctured before removal. An antibiotic solution is used to irrigate the breast pocket after implant removal. For more information about breast implant removal go to www.implantremoval.net or call Dr. Linder's office at 310-275-4513

Complex cataract and glaucoma surgery
Complex cataract and glaucoma surgery Scott 7,080 Views • 3 years ago

Phacolytic glaucoma usually is associated with a mature or hypermature cataract and typically occurs in elderly patients. Today, phacolytic glaucoma is rare in the United States, found primarily in areas where access to care is poor. Will the increase in the number of under- and uninsured patients lead to an increase in this condition? Evaluation and Diagnosis Signs and symptoms. Patients typically report acute-onset pain, decreased vision, tearing and photophobia. Examination will reveal injection, corneal edema, elevated IOP, anterior chamber reaction with or without pseudohypopyon, particles on the lens capsule and anterior capsule wrinkling. Patient history. The duration of symptoms should be elicited; a delayed presentation of more than five days since onset can result in glaucomatous disc damage and poorer prognosis.¹ The ocular history may reveal that the patient decided against removal of an advanced cataract. Prior intraocular surgery or trauma may have left residual lens material that could cause phacoanaphylactic glaucoma or exacerbate infectious endophthalmitis. Visual acuity and visual potential should be assessed. Exam essentials. A complete ophthalmologic examination should be done. The eye should be inflamed, and the cornea may be edematous due to the high IOP. The anterior chamber will demonstrate massive inflammation and/ or pseudohypopyon. Gonioscopy is essential; it will help rule out angle closure due to phacomorphic glaucoma or neovascularization of the angle. Assess ment of the posterior pole should be performed to rule out vitreous hemorrhage (which can result in ghost-cell glaucoma) or vitritis (which may be associated with infectious endophthalmitis or panuveitis). If the view to the fundus is obstructed, B-scan ultrasonography also should be performed. Differential diagnosis. The differential diagnosis includes infectious endophthalmitis, phacoanaphylactic glaucoma, inflammatory glaucoma, glaucoma secondary to intraocular tumor, phacomorphic glaucoma, acute-angle closure glaucoma and neovascular glaucoma. Management Medication. Medical management is used to temporarily control the glaucoma and inflammation. Initial treatment consists of hyperosmotic agents, aqueous suppressants, anti-inflammatory drugs and cycloplegics. Surgery. Definitive treatment is removal of the lens via extracapsular cataract extraction with or without an IOL. Some ophthalmologists defer placement of an IOL until after the inflammation subsides; however, there is no significant difference in final visual acuity between those patients who did receive an IOL and those who did not.¹ If the phacolytic glaucoma is of long duration (more than seven days), a combined trabeculectomy may be needed to prevent postoperative IOP spikes.² In eyes with hypermature Morgagnian cataracts, one must be especially careful, as the capsule is fragile, the zonules are weak and the view is difficult due to the white, milky cortex. Vision limited to light perception on presentation is not a contraindication to performing cataract extraction. Surgical Tips For a planned extracapsular cataract extraction with a posterior chamber IOL, fashion a superior fornix-based conjunctival flap.³ Make a partial-thickness incision along the sclerolimbal junction superiorly for 120 degrees with a No. 69 blade. Forty-five degrees away, a paracentesis should be done to decompress the eye. The anterior chamber fluid can be withdrawn for analysis, to look for macrophages and high molecular-weight proteins. Inject balanced salt solution in a cannula to wash out any residual particulate matter, then inject Healon or viscoelastic into the anterior chamber. Make an incision entering the anterior chamber at the 12 o’clock position with a keratome. A 26-gauge cystotome mounted on a syringe is then introduced through the 12 o’clock incision and used to puncture the capsular bag. The milky cortex should be aspirated as much as possible, until the nucleus is visible. Withdraw the needle through the keratome incision, then inject Healon through the 12 o’clock incision into the capsular bag. Next, enlarge the corneoscleral keratome incision with curved Westcott scissors to 120 degrees. Perform a partial V-shaped capsulotomy; this can be done either with the cystotome or with an angled Vannas scissors. Place viscoelastic under the nucleus to float the nucleus and sever any adhesions between the nucleus and the capsule. The nuclear portion of the lens can then be removed with an irrigating vectis (lens loop) with or without gentle pressure at the inferior limbus (6 o’clock). Irrigate and aspirate the residual cortex with the Simcoe cannula. Inspect the capsular bag; if it is intact, place a posterior chamber IOL into the bag. Close the incision with several interrupted 10-0 monofilament nylon sutures and reattach the conjunctival flap. Potential Sequelae and Prognosis Postoperatively, the patient should be managed with topical steroids and/or aqueous suppressants and hyperosmotics if necessary. Vitreous opacification behind the posterior capsule occurs in a small percentage of eyes. These vitreous opacities are typically absorbed by one to two weeks postoperatively. IOP usually is controlled without antiglaucoma medications after the cataract removal. A detailed glaucoma evaluation (including repeat gonioscopy to assess for peripheral anterior synechiae, visual field and optic nerve status) should be done to assess the extent of glaucomatous damage. The prognosis is dependent on the duration of elevated IOP, PAS and optic nerve damage. In one study, patients who were older than 60 and whose glaucoma was present for more than five days did significantly worse than a comparison group of younger individuals with shorter disease duration.

If you are a healthy, non-smoking women who are at or near their ideal weight, with enough of their own breast tissue to cover and support an implant adequately, then you are a good candidate for breast augmentation surgery.
