Abdominal Aneurism RepairAn aortic aneurysm is a bulging, dilation or ballooning in the wall of a blood vessel, usually an artery, that is due to weakness or degeneration that develops in a portion of the avenue wall. Merely like a balloon, the aneurysm enlarges, stretching the walls of the avenue thinner which compromises the artery wall's ability to stretch any further. At this indicate, an aneurysm is at gamble of rupturing and causing  potentially fatal bleeding, merely as a airship will popular when blown up too much.

UCSF has a world-renowned program in endovascular surgery, ane of the largest and oldest in existence. Vascular surgeons at UCSF have all-encompassing experience in performing technically challenging surgeries for complex aortic aneurysms, such equally those involving arteries running to the kidneys and intestines, and accept pioneered many endovascular procedures for treating aneurysms in use today.

UCSF Medical Centre earned a "high performance" rating – the highest rating possible – for abdominal aortic aneurysm repair in theU.South. News & Earth Written report 2018-2019 All-time Hospitals survey, which evaluated data from more than 4,500 hospitals nationwide.

Abdominal Endovascular Aneurysm Repair (EVAR)

The best method to repair an aneurysm depends upon several factors, including the location and shape of the aneurysm as well as the physical condition of the patient. Endovascular grafting is a minimally invasive method to treat an aortic aneurysm. Instead of an open aneurysm repair in which your chest and abdomen are surgically opened, your surgeon may consider a procedure chosen an endovascular aneurysm repair (EVAR).

Intestinal aortic aneurysm repair is a procedure used to treat an aneurysm (abnormal enlargement) of the abdominal aorta. Repair of an abdominal aortic aneurysm may be performed surgically through an open incision or in a minimally-invasive procedure chosen endovascular aneurysm repair (EVAR). In the EVAR procedure, a stent graft (a fabric tube supported by metal wire stents that reinforces the weak spot in the aorta) is inserted into the aneurysm through small incisions in the groin. Endovascular repair of aneurysms does not crave a large incision and has a substantially shorter recovery than the conventional open surgical approach. Even so, not all aneurysms are suitable for endovascular repair.

And then, using an x-ray to run into the artery, the surgeon threads the graft (likewise chosen a stent graft) into the aorta to the aneurysm. The graft is then expanded inside the aorta and fastened in place to form a stable aqueduct for blood flow. The graft reinforces the weakened section of the aorta to preclude the aneurysm from rupturing.

The illustration to the right shows the placement of an endovascular stent graft in an aortic aneurysm. In figure A, a catheter is inserted into an avenue in the groin (upper thigh). The catheter is threaded to the intestinal aorta, and the stent graft is released from the catheter. In figure B, the stent graft allows blood to flow through the aneurysm.

Endovascular repair reduces recovery time to a few days and greatly reduces fourth dimension in the hospital. All the same, surgeons tin't repair all aortic aneurysms with this process. The location or size of the aneurysm may prevent a stent graft from beingness safely or reliably placed inside the aneurysm.

Branched Arch Aneurysm Repair

Aneurysms forth the aortic arch are rare and are the most complex to care for, largely because the arterial branches that supply blood to the brain and upper extremities are fastened along the aortic curvation. A customized branched endograft has graft limbs that branch off of the master portion of the device to directly provide claret menstruation to the kidneys, liver, stomach, intestines, and the visceral arteries.

This device is not approved for widespread utilise in the United states. Information technology tin can but be used under the support of an investigational device exemption from the FDA –this trial is referred to equally the "TAAA trial". The electric current phase of this study began in 2005, using an industry-made version of the multi-branched stent-graft to treat over 100 patients and so far.

Thoracic Endovascular Aneurysm Repair (TEVAR)

Thoracic aortic aneurysms are those that occur along the aorta above the diaphragm, the partition between the breast and abdomen, including the ascending aorta, the aortic arch, and the descending thoracic aorta. A thoracic aortic aneurysm is a burl in the aorta which tin cause the aorta's diameter to airship to several times its normal size. Such an aneurysm may rupture, leading to extensive internal bleeding that is oft fatal. TEVAR was initially developed to treat patients who were considered to not exist surgical candidates only is now considered a suitable alternative to open surgery in most cases.

When handling becomes necessary for a TAA, medical management is oftentimes the starting time choice - including reducing blood pressure, quitting smoking and lowering cholesterol in the patient's diet. All the same, medical management is not considered a "set up" for TAA - information technology just reduces the stresses on the aneurysm.

Vascular surgeons at UCSF have been pioneers in the field of endovascular aneurysm repair for the intestinal and thoracic aorta. Our main investigators are likewise leadingclinical trials seeking to develop state-of-the-art endovascular devices to advance the treatment of aortic aneurysms.
