Coarctation of the aorta (CoA[1][2] or CoAo), also called aortic narrowing, is a congenital condition whereby the aorta is narrow, usually in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts. The word “coarctation” means narrowing. Coarctations are most common in the aortic arch. The arch may be small in babies with coarctations. Other heart defects may also occur when coarctation is present, typically occurring on the left side of the heart. When a patient has a coarctation, the left ventricle has to work harder. Since the aorta is narrowed, the left ventricle must generate a much higher pressure than normal in order to force enough blood through the aorta to deliver blood to the lower part of the body. If the narrowing is severe enough, the left ventricle may not be strong enough to push blood through the coarctation, thus resulting in lack of blood to the lower half of the body. Physiologically its complete form is manifested as interrupted aortic arch
For benign colorectal diseases, totally laparoscopic left-sided colectomy was already reported on some papers. Nowadays, there is increasingly demanded minimally invasive surgerys on malignant bowel diseases including colorectal cancers and so we developed the new techniques in that specimen is del...ivered through the open rectal stump, especially, using Sani Sleeve(TM). In this operation video, you can see that an anvil was fixed to proximal colonic stump with intracorporeal purse-string suture using Endo-stitch(TM). (SETA : Specimen Extraction Through Anus)
In neonates, hypocalcemia is more likely to occur in infants born of diabetic or preeclamptic mothers. Hypocalcemia also may occur in infants born to mothers with hyperparathyroidism. Clinically evident hypocalcemia generally presents in milder forms and is usually the result of a chronic disease state. In emergency department patients, chronic or subacute complaints secondary to mild or moderate hypocalcemia are more likely to be a chief complaint than severe symptomatic hypocalcemia. Once laboratory results demonstrate hypocalcemia, the first question is whether the hypocalcemia is true—that is, whether it is representative of a decrease in ionized calcium. The presence of chronic diarrhea or intestinal disease (eg, Crohn disease, sprue, chronic pancreatitis) suggests the possibility of hypocalcemia due to malabsorption of calcium and/or vitamin D. The patient's past medical history should be explored for pancreatitis, anxiety disorders, renal or liver failure, gastrointestinal disorders, and hyperthyroidism or hyperparathyroidism. Previous neck surgery suggests hypoparathyroidism; a history of seizures suggests hypocalcemia secondary to anticonvulsants. The patient may have a recent history of thyroid, parathyroid, or bowel surgeries or recent neck trauma. The length of time that a disorder is present is an important clue. Hypoparathyroidism and pseudohypoparathyroidism are lifelong disorders. Instead, acute transient hypocalcemia may be associated with acute gastrointestinal illness, nutritional deficiency, or acute or chronic renal failure. In an elderly patient, a nutritional deficiency may be associated with a low intake of vitamin D. A history of alcoholism can help diagnose hypocalcemia due to magnesium deficiency, malabsorption, or chronic pancreatitis. Inquire about recent use of drugs associated with hypocalcemia, including the following: Radiocontrast Estrogen Loop diuretics Bisphosphonates Calcium supplements Antibiotics Antiepileptic drugs Cinacalcet Other considerations in the history include the following: Family history of hypocalcemia Low-calcium diet Lack of sun exposure
It may be reassuring to know spotting or bleeding after sex is common and can come from the vagina, cervix, or urinary tract. It occurs most commonly in women 20 to 40 years old. Cervical Cancer: A very rare cause of spotting. ... Vaginal Dryness: Often caused by inadequate foreplay or vaginal lubrication.
Microsurgical bipolar cautery tonsillectomy compares favorably with traditional techniques in terms of intraoperative bleeding, postoperative pain, otalgia, and hemorrhage. This technique combines the hemostatic advantage of cautery dissection, the excellent visualization achieved by a microscope, and, with the use of a video, greatly improves the physician's ability to teach how to perform a tonsillectomy.
This form of liver cancer is called primary liver cancer. Noncancerous, or benign, liver tumors are common. They do not spread to other areas of the body, and they usually do not pose a serious health risk. In most cases, benign liver tumors are not detected because they cause no symptoms.
Dr. Debbie Song at Gillette Children's describes in detail selective rhizotomy surgery.
A selective dorsal rhizotomy is an operation performed to treat spasticity. It is thought that high tone and spasticity arise from abnormal signals that are transmitted through sensory or dorsal nerve roots to the spinal cord. In a selective dorsal rhizotomy we identify and cut portions of the dorsal nerve roots that carry abnormal signals thereby disrupting the mechanisms that lead to spasticity. Potential patients go through a rigorous assessment that includes an in-depth gait and motion analysis as well as a physical therapy evaluation.
They are evaluated by a multidisciplinary team that includes a pediatric rehabilitation doctor, a neurosurgeon, and an orthopedist, Appropriate patient selection is vital. Ideal candidates for selective dorsal rhizotomy are children who are between four and ten years of age, have a history of being born prematurely, and have a diagnosis of diplegia cerebral palsy. These patients usually walk independently or with the assistance of crutches or a walker. They typically function at a level one, two, or three in the gross motor function classification system or gmfcs. A selective dorsal rhizotomy involves the coordinated efforts of the neurosurgery, physiatry, anesthesia and nursing teams. The operation entails making an incision in the lower back that is approximately six to eight inches long. We perform what we call a laminoplasty in which we remove the back part of the spinal elements from the lumbar one or l1 to l5 levels. At the end of the procedure the bone is put back on. We identify and open up the Dural sac that contain the spinal fluid spinal cord and nerve roots. Once the Dural sac is opened ,we expose the lumbar and upper sacral nerve roots that transmit information to and from the muscles of the lower extremities.
At each level we isolate the dorsal nerve root, which in turn is separated into as many as 30 smaller thread light fruitlets.
Each rootlet is then electrically stimulated. Specialized members of the physiatry team look for abnormal responses in the muscles of the legs as each rootless is being stimulated. If an abnormal response is observed then the rootlet is cut.
If a normal response is observed, then the rootlet is not cut. We usually end up cutting approximately 20 to 40 percent of the rootlets. The Dural sac is sutured closed and the l1 through l5 spinal elements are put back into anatomic position, thus restoring normal spinal alignment. The overlying tissues and skin are then closed and the patient is awoken from surgery. The entire operation takes between four and five hours. A crucial component to the success of our rhizotomy program is the extensive rehabilitation course following surgery. With their tone significantly reduced after a rhizotomy, patients relearn how to use their muscles to walk more efficiently through stretching, strengthening, and gait training. Approximately one to two years after a rhizotomy patients undergo repeat gait and motion analysis. The orthopedic surgeons assess the need for interventions to correct bone deformities, muscle contractures, poor motor control, impaired balance, or other problems related to cerebral palsy.
At Gillette we work closely with patients and families to ensure that our selective dorsal rhizotomy program meets their goals for enhancing their function and improving their quality of life.
