Protamine reverses the effect of unfractionated heparin, but only partially binds to and reverses LMWH. A dose of 1 mg protamine / 100 IU LMWH reverses 90% of its anti-IIa and 60% of anti-Xa activity, but the clinical effect of the residual anti-Xa activity is not known. Both anti-IIa and anti-Xa activity may return up to three hours after protamine reversal, possibly due to release of additional LMWH from depot tissues.

Warfarin, heparin and LMWH do not seem to pass into breast milk, so these are not contraindicated in breastfeeding.

One approach used for treatment is embolization. A six-vessel angiogram is employed to determine the vascular supply to the fistula. Detachable coils, liquid embolic agents like NBCA, and onyx, or combinations of both are injected into the blood vessel to occlude the DAVF. Preoperative embolization can also be used to supplement surgery.

Small breast hematomas that cause no discomfort often require merely clinical observation, with ultrasound being used to monitor the resolution of the hematoma.

Large breast hematomas, or those that are not becoming smaller or that are causing discomfort, usually require drainage. Also hematomas that occur after surgery for excision of a malignant tumor are drained, because a hematoma to which irradiation is applied is unlikely to ever resolve. A recent hematoma can be drained by means of needle aspiration or (rarely) open surgical drainage.

DAVFs are also managed surgically. The operative approach varies depending on the location of the lesion.

Stereotactic radiosurgery

Stereotactic radiosurgery is used obliterating DAVFs post-embolization, and is considered an important adjunct. Use of this method, however, is limited to benign DAVFs that have failed other treatments.

Treatment can be either conservative or active. Active treatments can be divided into surgical and non-surgical treatments. Newer methods including endovenous laser treatment, radiofrequency ablation and foam sclerotherapy appear to work as well as surgery for varices of the greater saphenous vein.

Treatment usually includes antibiotics, and reducing the mobility of the affected region, either with a back brace or a plaster cast. Without treatment, the patient may form an abscess which may need to be surgically corrected. Due to the poor vascularity of the disc, drugs required for treatment often include potent agents such as Ciprofloxacin along with Vancomycin. Occasionally, oral drugs can be used to treat the infection but it may fail and IV drugs may be required.

If the patient is an adult many surgeons and doctors now recommend moving little and often and within the pain limits of the medication. Discs respond to osmotic pressure therefore movement is beneficial to increase their blood flow and fluid dynamics. This is why disc patients are no longer told to bed rest. In children whether to bed rest or move a little is decided on an individual basis, depending on the site and severity of the discitis.

The National Institute for Health and Clinical Excellence (NICE) produced clinical guidelines in July 2013 recommending that all people with symptomatic varicose veins (C2S) and worse should be referred to a vascular service for treatment. Conservative treatments such as support stockings should not be used unless treatment was not possible.

The symptoms of varicose veins can be controlled to an extent with the following:

- Elevating the legs often provides temporary symptomatic relief.

- Advice about regular exercise sounds sensible but is not supported by any evidence.

- The wearing of graduated compression stockings with variable pressure gradients (Class II or III) has been shown to correct the swelling, nutritional exchange, and improve the microcirculation in legs affected by varicose veins. They also often provide relief from the discomfort associated with this disease. Caution should be exercised in their use in patients with concurrent peripheral arterial disease.

- The wearing of intermittent pneumatic compression devices have been shown to reduce swelling and increase circulation

- Diosmin/hesperidin and other flavonoids.

- Anti-inflammatory medication such as ibuprofen or aspirin can be used as part of treatment for superficial thrombophlebitis along with graduated compression hosiery – but there is a risk of intestinal bleeding. In extensive superficial thrombophlebitis, consideration should be given to anti-coagulation, thrombectomy, or sclerotherapy of the involved vein.

- Topical gel application helps in managing symptoms related to varicose veins such as inflammation, pain, swelling, itching, and dryness.

The main goal of treatment is to remove the cause of the phlegmonous process in order to achieve effective treatment and prevention of recidives.

If the patient's condition is mild and signs of inflammatory process are present without signs of infiltrates, then conservative treatment with antibiotics is sufficient.

If the patient's condition is severe, however, immediate operation is usually necessary with application of drainage system. All of these are done under general anaesthesia. During operation, the cavity or place of phlegmonous process are washed with antiseptic, antibiotic solutions and proteolyic ferments.

In post-operative period, patients are treated with intravenous antibiotics, haemosorbtion, vitaminotherapy. Additionally, the use of i/v or i/m antistaphylococci γ-globulin or anatoxin can be taken as immunotherapy.

During operation of phlegmon dissection at any location, it is important:

1. to avoid spreading of pus during operation;

2. to take into account the cosmetic value of the operating site, especially when treating phlegmmonous process of the face; and

3. to avoid damaging nerves.

Cerebral vasospasm is the prolonged, intense vasoconstriction of the larger conducting arteries in the subarachnoid space which is initially surrounded by a clot.

Significant narrowing develops gradually over the first few days after the aneurysmal rupture. This spasm usually is maximal in about a week's time following haemorrhage.

Vasospasm is the one of the leading causes of death after the aneurysmal rupture along with the effect of the initial haemorrhage and later bleeding.

Treatment is directed at the prevention of haemorrhagic shock. Standard dose prednisolone does not increase the platelet count. High-dose methylprednisolone therapy in children with Onyalai has been shown to improve platelet count and reduce the requirement for transfusions. Vincristine sulphate may be of benefit to some patients. Splenectomy is indicated in patients with severe uncontrollable haemorrhage. High-dose intravenous gammaglobulin may help in increasing the platelet count and cessation of haemorrhage.

Fasting guidelines often restrict the intake of any oral fluid after two to six hours preoperatively. However, it has been demonstrated in a large retrospective analysis in Torbay Hospital that unrestricted clear oral fluids right up until transfer to theatre could significantly reduce the incidence of postoperative nausea and vomiting without an increased risk in the adverse outcomes for which such conservative guidance exists.

If ongoing and rapid haemorrhage is occurring then immediate delivery of the foetus may be indicated if the fetus is sufficiently developed. If the haemorrhage has already occurred and now stopped, an inutero transfusion of red cells to the foetus may be recommended.

Vascular occlusion is a blockage of a blood vessel, usually with a clot. It differs from thrombosis in that it can be used to describe any form of blockage, not just one formed by a clot. When it occurs in a major vein, it can, in some cases, cause deep vein thrombosis. The condition is also relatively common in the retina, and can cause partial or total loss of vision. An occlusion can often be diagnosed using Doppler sonography (a form of ultrasound).

Some medical procedures, such as embolisation, involve occluding a blood vessel to treat a particular condition. This can be to reduce pressure on aneurysms (weakened blood vessels) or to restrict a haemorrhage. It can also be used to reduce blood supply to tumours or growths in the body, and therefore restrict their development. Occlusion can be carried out using a ligature; by implanting small coils which stimulate the formation of clots; or, particularly in the case of cerebral aneurysms, by clipping.

Emergency exploratory laparotomy with cesarean delivery accompanied by fluid and blood transfusion are indicated for the management of uterine rupture. Depending on the nature of the rupture and the condition of the patient, the uterus may be either repaired or removed (cesarean hysterectomy). Delay in management places both mother and child at significant risk.

Because no currently available antiemetic is especially effective by itself, and successful control is often elusive, experts recommend a multimodal approach. Anaesthetic strategies to prevent vomiting include using regional anaesthesia wherever possible and avoiding medications that cause vomiting. Medications to treat and prevent postoperative nausea and vomiting is limited by both cost and the adverse effects. People with risk factors probably warrant preventative medication, whereas a "wait and see" strategy is appropriate for those without risk factors.

Percutaneous Coil Embolization of the aberrant obturator artery was performed. Arterial flow rapidly improved through the left dorsal penile artery, and brisk opacification was seen through to the glans penis. Post-procedure, the patient experienced an immediate improvement in erectile function.

Small breast hematomas often resolve on their own within several days or weeks by means of reabsorption of the blood. Larger hematomas are more likely to lead to inflammation or fibrosis.

Breast hematomas can sometimes lead to skin discoloration, inflammation, or fever. When a hematoma resolves, it may become fibrotic, leaving behind scar tissue. A resolving hematoma may liquify to form a seroma.

Post-surgical breast hematomas can also impede wound healing and therefore impact the cosmetic outcome. Hematomas are furthermore one of the risk factors for breast surgical site infections. There is preliminary evidence that, after breast implant surgery, the presence of hematoma increases the risk of developing capsular contracture.

In mammography screening, scar tissue resulting from a breast hematoma can easily be confused with tumor tissue, especially in the first years following surgery. Ultimately, fat necrosis may occur in the concerned region of the breast.

Rasmussen's aneurysm is a pulmonary artery aneurysm adjacent or within a tuberculous cavity. It occurs in up to 5% of patients with such lesions. It may lead to rupture and haemorrhage. It is named after Fritz Valdemar Rasmussen. It is quoted as the cause of hemoptysis in tuberculosis patients.

While the "classic" terminology relates the lesion to cavitary tuberculosis, the term is now used for the anatomic aneurysm associated with other destructive lung lesions. Even when the pulmonary aneurysm is present, the actual bronchial bleeding may be from the bronchial artery, rather than from the pulmonary artery.

Penile Revascularization is a specialized vascular-surgical treatment option for Erectile Dysfunction. The 2009 International Consultation on Sexual Dysfunctions recommended that revascularization be limited to nonsmoker, nondiabetic men younger than 55 years of age with isolated stenosis of the internal pudendal artery with absence of venous leak.

Patients with persistent erectile dysfunction after revascularization may benefit from repeat penile duplex ultrasound and pelvic angiography to evalauate the status of the bypass graft and to exclude the presence of a PASS as the cause. The prevalence of an aberrant obturator artery arising from the inferior epigastric artery is approximately 10.5%. If an aberrant obturator artery is visualized arising from the inferior epigastric artery prior to surgical penile revascularization, consideration should be given toward using an alternative source artery or to embolization to avoid the creation of a Penile Artery Shunt Syndrome encountered in this described case.

Treatment includes anti-inflammatory medications and immobilization of the neck in addition to treatment of the offending infectious cause (if any) with appropriate antibiotics. Early treatment is crucial to prevent long-term sequelae. Surgical fusion may be required for residual instability of the joint.

Non-displaced or minimally displaced fractures may be treated conservatively. Open reduction and internal fixation is reserved for cases that are severely angulated or comminuted. The purpose of fixation is to restore the normal appearance of the face. Specific attention is given to the position of the malar eminence and reduction of orbital volume by realigning the zygoma and sphenoid. Failure to correct can result in rotational deformity and increase the volume of the orbit, causing the eye to sink inwards.

Fractures with displacement require surgery consisting of fracture reduction with miniplates, microplates and screws. Gillie's approach is used for depressed zygomatic fractures. The prognosis of tripod fractures is generally good. In some cases there may be persistent post-surgical facial asymmetry, which can require further treatment.

Everolimus is FDA approved for the treatment of angiomyolipomas. Treatment should be considered for asymptomatic, growing AML measuring larger than 3 cm in diameter.

Angiomyolipoma do not normally require surgery unless there is life-threatening bleeding. Some centres may perform preventative selective embolisation of the angiomyolipoma if it is more than 4 cm in diameter, due to the risk of haemorrhage.

People with tuberous sclerosis are advised to have yearly renal scans, though it is possible that patients with very stable lesions could be monitored less frequently. The research in this area is lacking. Even if no angiomyolipoma is found, one can develop at any life stage. The angiomyolipoma can grow rapidly.

In tuberous sclerosis, typically many angiomyolipomas affecting each kidney. It is not uncommon for more than one intervention to be required during lifetime. Since kidney function may already be impaired (up to half the kidney may be lost before function loss is detectable), it is vital to preserve as much kidney as possible when removing any lesion. Large angiomyolipomas are treated by embolisation which reduces the risk of haemorrhage and can also shrink the lesion. A side effect of this treatment is postembolisation syndrome: severe pain and fever however this is easily managed and lasts only a few days.

A ruptured aneurysm in an angiomyolipoma leads to blood loss that must be stopped (though embolisation) and compensated for (through intravenous fluid replacement). Therefore, removal of the affected kidney (nephrectomy) is strongly discouraged though may occur if the emergency department is not knowledgeable about tuberous sclerosis.

Embolisation involves inserting a catheter along the blood vessels to the tumour. The blood vessels are then blocked, typically by injecting ethanol or inert particles. The procedure can be very painful, so analgesics are used. The destroyed kidney tissue often causes post-embolisation syndrome, which manifests as nausea, vomiting, fever and abdominal pain, and lasts a few days. Embolisation (in general) has an 8% rate of morbidity and a 2.5% rate of mortality, so is not considered lightly.

Patients with kidney loss should be monitored for hypertension (and treated for it if discovered) and avoid nephrotoxic drugs such as certain pain relievers and IV contrast agents. Such patients who are unable to communicate effectively (due to age or intellectual disability) are at risk of dehydration. Where multiple or large angiomyolipomas have caused chronic kidney disease, dialysis is required.

Robotic assisted partial nephrectomy has been proposed as a surgical treatment of a ruptured angiomyolipoma combining the advantages both of a kidney preservation procedure and the benefits of a minimal invasive procedure without compromising the safety of the patient.

Treatment is directed at correcting the underlying cause. Post-surgical atelectasis is treated by physiotherapy, focusing on deep breathing and encouraging coughing. An incentive spirometer is often used as part of the breathing exercises. Walking is also highly encouraged to improve lung inflation. People with chest deformities or neurologic conditions that cause shallow breathing for long periods may benefit from mechanical devices that assist their breathing. One method is continuous positive airway pressure, which delivers pressurized air or oxygen through a nose or face mask to help ensure that the alveoli do not collapse, even at the end of a breath. This is helpful, as partially inflated alveoli can be expanded more easily than collapsed alveoli. Sometimes additional respiratory support is needed with a mechanical ventilator.

The primary treatment for acute massive atelectasis is correction of the underlying cause. A blockage that cannot be removed by coughing or by suctioning the airways often can be removed by bronchoscopy. Antibiotics are given for an infection. Chronic atelectasis is often treated with antibiotics because infection is almost inevitable. In certain cases, the affected part of the lung may be surgically removed when recurring or chronic infections become disabling or bleeding is significant. If a tumor is blocking the airway, relieving the obstruction by surgery, radiation therapy, chemotherapy, or laser therapy may prevent atelectasis from progressing and recurrent obstructive pneumonia from developing.

Small myelolipomas generally do not produce symptoms, and do not require treatment. Ongoing surveillance of these lesions by a doctor is recommended. Surgical excision (removal) is recommended for large myelolipomas because of the risk of bleeding complications.
