A co-medical director of the Southern California Center for Neuroscience and Spine, Ali Mesiwala, MD, is a reputable neurosurgeon and researcher in California. With more than 20 years of medical experience, Ali Mesiwala, MD, has written extensively on such topics as aneurysms.

Below are several types of aneurysms:

Aortic: These types of aneurysms occur in the aorta, the body’s largest blood vessel. Most aortic aneurysms occur in men over the age of 60 and are linked to high cholesterol, high blood pressure, smoking, and atherosclerosis, a hardening of the arteries. Aortic aneurysms can occur in either the chest cavity (thoracic aortic aneurysms) or the abdomen.

Cerebral: Also known as brain aneurysms, cerebral aneurysms occur in roughly 5 percent of people. They occur when the wall of a brain blood vessel bulges or becomes weakened. Cerebral aneurysms can occur in varying sizes and are associated with such symptoms as neck pain, double vision, and stiff neck.

Peripheral: Peripheral aneurysms are simply aneurysms that occur in areas of the body that aren’t the brain or aorta. For example, carotid artery aneurysms occur in the neck, visceral aneurysms happen in the arteries in the kidneys or bowel, and popliteal aneurysms occur behind the knee. Typically, peripheral aneurysms do not rupture as often as aortic aneurysms.


The Rhoton Collection – Funded by the AANS

Experienced neurosurgeon Ali Mesiwala, MD, serves as the chief of the Division of Neurological Surgery and Department of Surgery at St. Bernardine Medical Center in California. Possessing more than two decades of medical experience, Ali Mesiwala, MD, belongs to several professional organizations, including the American Association of Neurological Surgeons (AANS).

As part of its efforts to advance the specialty of neurological surgery, the AANS is funding the creation of the Rhoton Collection alongside the Neurosurgical Research & Education Foundation (NREF). Created by Albert L. Rhoton, Jr., MD, FAANS(L), this online archive was designed to help professionals increase their knowledge of neurosurgical anatomy in the most efficient way possible. It is free to AANS members who enter a username and password.

Within the Rhoton Collection, professionals will find thousands of resources from Dr. Rhoton’s teaching material. This material includes video lectures and an interactive atlas of anatomical structures. Tens of thousands of slides are being scanned for inclusion in the collection, and volunteers are creating drawings to accompany the anatomical components found in the interactive atlas.

All the material found in the Rhoton Collection can be downloaded in high resolution and used for publications, media use, or education presentations. However, credit must be given to the Rhoton Collection if any materials are used and watermarks cannot be removed from videos or images.

Three Neurological Symptoms That May Warrant a Trip to the Doctor

For more than a decade, Ali Mesiwala, MD, has been working as a neurosurgeon in California. He completed his postdoctoral training at such institutions as the University of Washington and the International Neurosciences Institute. Currently, Ali Mesiwala, MD, serves as the chief of the Department of Surgery and Division of Neurological Surgery at St. Bernardine Medical Center.

There are several neurological signs and symptoms that have simple explanations, but some may be early indications of a serious problem. Following are just a few examples of neurological problems that may warrant a trip to your physician:

1. Numbness or weakness: feeling numbness on one side of the face can be an early sign of a stroke. However, these early symptoms are often brief, so many individuals forget about them. In addition to signalling a stroke, sudden muscle weakness may indicate various disorders, including Guillain-Barre syndrome or myasthenia gravis.

2. Vision loss: unexpected loss of vision in one or both eyes can indicate various infections, multiple sclerosis, or location-specific strokes. An optic nerve stroke can cause complete blindness in one eye. Meanwhile, deteriorating vision accompanied by eye pain may suggest that the optic nerve has become inflamed.

3. Persistent dizziness: any persistent problems with coordination and balance can indicate that something is wrong. Certain inner ear conditions, such a positional vertigo, may be the cause of these problems, but they also may result from strokes in the brain stem. The brain stem connects the brain and spine and strokes can interrupt these important communications.

An Innovative Approach to SI Joint Fixation Surgery

Based in Pomona, California, neurosurgeon Ali Mesiwala, MD, serves as medical director of Chaparral Medical Group, Inc. Well-published in his field and a member of SI Bone, Inc., Ali Mesiwala, MD, coauthored the presentation “One Year Follow-up of Patients Undergoing Minimally Invasive Sacroiliac Joint Fixation” through the Southern California Center for Neuroscience and Spine.

Traditional open sacroiliac (SI) joint fixation surgeries are associated with physical restrictions and long patient recovery times. In recent years, a minimally invasive approach that employs three titanium dowels has been developed for fixating the SI joint.

A review of nearly 100 patients who had not responded to non-surgical treatment and went through unilateral or bilateral SI fixation for degenerative joint disease/instability revealed significant post-operative improvement. Among patients without previous lumbar surgery, success was achieved within six months. Those with prior lumbar surgery achieved successful results within three months. In addition to these positive results, Dr. Mesiwala and his colleagues noted that there was no evidence of permanent complications, and patients reported no physical limitations.
